Abstract
Objectives
Informal carers are an integral part of any health care system. However, provision of informal care is associated with caregiver burden and decreased wellbeing. Mindfulness programs can reduce caregiving burden and improve wellbeing among informal carers, but they face challenges when participating in face-to-face programs. Studies have explored the effects of online delivery of mindfulness programs for informal carers. However, the enablers and barriers for participation are not well understood. This review aimed to synthesise the evidence and provide a comprehensive understanding of the enablers and barriers to participation in online mindfulness programs among this population.
Methods
A mixed-methods systematic review was conducted following the Joanna Briggs Institute mixed-methods systematic review approach and using eight databases. All empirical studies published in English and involving informal carers aged over 18 years were included. Critical appraisal was conducted using the Mixed Methods Appraisal Tool. Thematic analysis was conducted to integrate the data.
Results
Nine studies were included: three quantitative, two qualitative, and four mixed methods. Three subthemes for enablers and barriers were developed. Three subthemes for enablers included self-motivation, positive experience of mindfulness, and program structure and delivery. Three subthemes for barriers included lack of self-motivation, external factors preventing participation, and program structure and delivery. The enablers and barriers were interrelated within and across the identified themes.
Conclusions
A comprehensive synthesis of current evidence was provided for consideration when developing online mindfulness-based interventions for informal carers. Further investigation is recommended, particularly in relation to the enablers and barriers to engagement by informal carers.
Preregistration
The review protocol was registered with PROSPERO (CRD42023409311).

Informal carers are defined as individuals who provide care for family members, friends, or neighbours on a voluntary basis (Australian Institute of Health and Welfare, 2023). Informal carers fulfill an important role within the Australian health care system by enabling care recipients to continue living in their communities (Carers Australia, 2021). Approximately 10% of Australians are informal carers who provide care recipients with basic care, including activities of daily living, communication, and mobility (Australian Institute of Health and Welfare, 2023). Caregiving often predisposes carers to an increased risk of stress, burden, and depression (Kor et al., 2018) and decreased psychological wellbeing (Cunningham et al., 2019). Caregiving demands may also limit the ability of informal carers to engage in paid work or to participate in social and leisure activities (Australian Institute of Health and Welfare, 2023), which in turn can lead to feelings of isolation and ultimately reduced quality of life (Brown et al., 2017).
Emerging evidence suggests that quality of life within the informal carer population can be improved by engaging with mindfulness activities (Contreras et al., 2022; Juberg et al., 2023; Simpson et al., 2023). Mindfulness-based interventions (MBI) have been defined as psychological interventions that combine the mind and body to decrease stress (Kor et al., 2018). Mindfulness-based interventions have been utilised within different populations of carers including those of people with dementia (Chacko et al., 2022) and identified as a valuable psychological intervention (Kor et al., 2018), yielding positive effects on health and wellbeing in this population, reducing mental health conditions (Appleton et al., 2020), depression, cancer, and cardiovascular disease (Parkinson et al., 2019).
MBI have traditionally been delivered in face-to-face modes (Kabat-Zinn, 1982; Segal et al., 2002), but are being increasingly delivered online via pre-recorded guidance (Bailey et al., 2018), or via online courses with synchronous mindfulness practice sessions (Bogosian et al., 2021; Cavalera et al., 2019; Krusche et al., 2012). There are also many asynchronous online mindfulness applications available, with Headspace and Calm being two popular examples (Flett et al., 2019). Online mindfulness programs rapidly increased in popularity during the COVID-19 pandemic due to social distancing and enforced lock-downs (Zhang et al., 2020). Often during the pandemic, informal carers chose to self-isolate to reduce the risk of transmission to their care recipient (Bailey et al., 2022), making online interventions ideal for them. It is well recognised that this pandemic had a detrimental impact on people’s mental wellbeing (Santomauro et al., 2021; Torales et al., 2020), including that of informal carers (Allen et al., 2022; Hughes et al., 2021; Rippon et al., 2023). Online access to MBI is particularly suitable for informal carers due to the remote delivery which allows them to balance the competing demands of care duties, particularly if they need to be at home with the care recipient, negating the need to make alternative care giving plans (Bogosian et al., 2021; Price-Blackshear et al., 2020). Asynchronous online applications, in particular, enable participants to access the course at their convenience (Mrazek et al., 2019), maintain their privacy (Price-Blackshear et al., 2020), and select activities based on individual preferences (Huberty et al., 2019).
Several systematic reviews have identified that online MBI may improve the mental health outcomes of a range of populations including students, employees, and patients (Gal et al., 2021; Jayawardene et al., 2017; Sommers-Spijkerman et al., 2021; Witarto et al., 2022; Zhang et al., 2020). Despite the positive health outcomes of online MBI delivery reported in the literature, these studies have also identified poor adherence and high attrition among the participants (Linardon & Fuller-Tyszkiewicz, 2020; Torous et al., 2020; Yadav et al., 2022).
Whilst there is a paucity of systematic reviews exploring the barriers and enablers to MBI in informal carers, a recent systematic review among people with chronic conditions found adherence to the therapy can be enhanced with greater understanding of the program’s benefits, and by providing individualised support during practice (Marks et al., 2022), whereas barriers identified within previous research included time commitment, poor computer skills, health issues, and less motivation (Marks et al., 2022). To the best of our knowledge, there is no review conducted which explores the barriers and enablers of online MBI for informal carers. A preliminary search of PROSPERO, MEDLINE, the Cochrane Database of Systematic Reviews, and Joanna Briggs Institute (JBI) Evidence Synthesis was conducted, whereby no current or in-progress systematic reviews on the topic were identified. Therefore, this systematic review aimed to identify and explore the barriers and enablers of online MBI for informal carers.
Method
Review Design
This review followed the JBI methodology for mixed-methods systematic reviews (MMSR) featuring as a guide to synthesise and integrate qualitative, quantitative, and mixed-methods studies (Lizarondo et al., 2020). The protocol for the systematic review was developed via collaboration between all authors and registered with the International Prospective Register of Systematic Reviews, on 1 April 2023 before data extraction commenced (CRD42023409311).
Search Strategy
A three-step search strategy was utilised in this review, in accordance with the JBI methodology (JBI, 2020). First, an initial limited search was undertaken using MEDLINE (Ovid) and PsycINFO (EBSCO) to identify the keywords and Mesh terms used. Second, the search was replicated using the finalised keywords and Mesh terms in the other databases including CINHAL Ultimate (EBSCO host), Web of Science, Cochrane Library, JBI, Scopus, and Embase (Elsevier). The search also included sources of unpublished studies and grey literature, such as ClinicalTrials.gov and BASE. The search strategy, including all identified keywords and index terms, was adapted for each included information source, whereby a second search was undertaken on 14 March 2023 prior to data analysis. A final search was undertaken on 01 January 2024 to identify any recent publications that were eligible for inclusion. The applied full search strategies are provided in Table S1 of the Supplementary Information. Lastly, a hand search was conducted to review the reference lists of selected study for critical appraisal, and Google Scholar searched to identify any articles missed by the database search.
Eligibility Criteria
Quantitative, qualitative, and mixed-methods studies that included data relevant to the research question were considered for inclusion in the review. Mixed-methods studies that contained data from quantitative or qualitative components that could be extracted were also considered. Whilst grey literature comprising theses were included, we excluded letters to the editor, opinion pieces, systematic reviews, and editorials. The search strategy was guided by the PICo mnemonic: population, phenomena of interest, and context.
Population
This review considered studies that included informal carers aged 18 years and above. Studies that involved both informal carers and care recipients were included if findings related to informal carers could be extracted.
Phenomena of Interest
This review identified and explored the barriers and enablers that influence the delivery of online MBI, with the core component being the mindfulness-based activities. We included synchronous and asynchronous mindfulness-based stress reduction and mindfulness-based cognitive therapy, as well as any other intervention where mindfulness was the preliminary intervention. The review included studies with any data pertaining to barriers and enablers with no limits of period of intervention impacting informal carers in undertaking online MBI.
Context
This review considered literature describing the implementation of MBI within an online setting of any application. The duration of the intervention was not considered due to the scarcity of available literature in the area.
Study Selection
Following the search, all identified citations were uploaded into EndNote 20 for the removal of duplicates. The remaining studies were then exported to Covidence for title, abstract, and full-text screen (Covidence Systematic Review Software, 2023). Titles and abstracts were then screened by two independent reviewers from the study team for assessment against the inclusion criteria. The full text of selected citations was then assessed against the inclusion criteria by two independent reviewers from the study team for inclusion/exclusion. Disagreements between the reviewers at the full-text review stage accounted for 18% of the cases and were resolved through discussion with a third reviewer. The included articles were then exported back to Endnote. The results of the search and study selection are presented in a PRISMA flow diagram (Page et al., 2021) (Fig. 1).
Quality Appraisal
Critical appraisal of included studies was conducted using the Mixed Methods Appraisal Tool (MMAT), which was designed to appraise quantitative, qualitative, and mixed-methods studies (Hong et al., 2018). The MMAT comprises two screening questions to ensure selection of only empirical studies for appraisal. Each category has five criteria to rate with either “yes”, “no”, and “can’t tell” (Hong et al., 2018). Two study team members were involved in appraising the methodological quality of the included studies. Similarly, any disagreement with the appraisal was resolved via discussion with the third study team member. Due to limited studies being available, no study was excluded based on its methodological quality (Table 1).
Data Extraction and Synthesis
Data from the included studies were extracted and are presented in Table 2. These data included study design, aim of the study, study population, characteristics of participants (age, sex, relationship to care recipient), sample size and online intervention (program duration, recommended daily practice, delivery type audio/video/webinar), data collection methods, data analysis, results, and attrition rate. Empirical data concerning the barriers and enablers for online mindfulness interventions were also extracted and are presented in Table 3.
Data synthesis was conducted using the convergent integrated approach which involved combining the “qualitised” data and qualitative data (Lizarondo et al., 2020). “Qualitised data” refer to quantitative results from experimental, observational, and quantitative components of mixed-methods studies that were transformed into textual descriptions or narrative interpretation in a way that answered the review questions by repeated detailed examination (Hong et al., 2017).
Thematic synthesis was used to categorise and pool together data of similar meaning in order to form subthemes (Harden & Thomas, 2008). Following this, codes were developed for each subtheme and deductively organised under the main themes for “Enablers to practicing online mindfulness” and “Barriers to practicing online mindfulness” (Table 3). To explore relationships between subthemes and main themes, a concept map was used to illustrate the relationships within and between the descriptive subthemes and main themes (Novak & Canas, 2008) (Fig. 2). Concept mapping is a graphical tool used to organise and represent knowledge hierarchically (Eppler, 2006; Novak & Canas, 2008). Considering the aim of this review, key concepts relating to each descriptive theme were identified and ranked from the most general and comprehensive concept presented at the top to the more specific and least general concepts presented at the bottom.
Results
Search Outcome
The search resulted in 373 retrieved records from the databases, of which 236 were duplicates. Following screening of titles and abstracts, 11 studies were assessed for eligibility as full text, resulting in 4 studies being included in the review. Three studies were retrieved from the citation search, with 8 studies identified by hand searching and 6 studies identified by grey literature, of which, 5 studies met the inclusion criteria. Accordingly, a total of 9 studies were included, as illustrated in Fig. 1.
Methodological Quality of Included Studies
Both qualitative studies (Llaneza et al., 2022; Stjernsward & Hansson, 2020) had coherence between qualitative data sources, collection analysis, and interpretation with appropriate research questions for qualitative research followed by adequate data collection methods. Findings were also adequately derived from the data and results were sufficiently interpreted from data. All 4 mixed-methods studies (Atreya et al., 2018; Dragomanovich et al., 2021; Lunsky et al., 2021; Stjernsward & Hansson, 2017) had issues with interpretation of integration of qualitative and quantitative components. One study had issues with qualitative interpretation of results, and a lack of consideration for confounding factors (Dragomanovich et al., 2021). Another study had issues with sample selection, addressing divergences of quantitative and qualitative results, and the rationale for using a mixed-methods design (Stjernsward & Hansson, 2017). The other study also had issues with the rationale for a mixed-methods design, integration of findings, and interpretation of qualitative and quantitative results (Lunsky et al., 2021). Three randomised controlled trials had issues with blinded outcome assessors (Lange, 2020; Stjernsward & Hansson, 2018; Zarei et al., 2022). The methodological quality of the included studies is reported in Table 1.
Study Characteristics
Study characteristics in the included studies are summarised in Table 2. Three studies were published between 2017 and 2019 (Atreya et al., 2018; Stjernsward & Hansson, 2017, 2018), with 6 studies published since 2020 (Dragomanovich et al., 2021; Lange, 2020; Llaneza et al., 2022; Lunsky et al., 2021; Stjernsward & Hansson, 2020; Zarei et al., 2022). The studies were conducted in Canada (n = 2) (Lunsky et al., 2021; Zarei et al., 2022), the UK (n = 1) (Lange, 2020), Sweden (n = 3) (Stjernsward & Hansson, 2017, 2018, 2020), and the USA (n = 3) (Atreya et al., 2018; Dragomanovich et al., 2021; Llaneza et al., 2022). The sample sizes of studies ranged from 10 to 196 informal carers, whereby 2 studies included informal carers and care recipients with a total number of 69 participants (Dragomanovich et al., 2021) and 53 (Atreya et al., 2018), respectively. Eight studies reported the mean age of participants, ranging between 50 and 65 years of age (Atreya, 2018; Lange, 2020; Llaneza et al., 2022; Lunsky et al., 2021; Stjernsward & Hansson, 2017, 2018, 2020; Zarei et al., 2022). Three studies included over 90% female participants (Llaneza et al., 2022; Stjernsward & Hansson, 2017, 2020), whereby participant relationship to the care recipient was reported in all studies, of which 4 studies involved a majority of spouse/partner relationship (Lange, 2020; Stjernsward & Hansson, 2017, 2018, 2020). Three of the nine included studies (Stjernsward & Hansson, 2017, 2018, 2020) had the same online MBI as they were part of one larger study. One study had an audio-based intervention (Atreya et al., 2018), whereas other studies had both audio/video and web interventions. One study did not report the daily practice requirement; however, it included 14 levels of mindfulness training (Llaneza et al., 2022). Length of practice times were between 10 and 20 min daily for the remaining studies. Apart from daily practice, 3 studies provided weekly webinars for online MBI (Dragomanovich et al., 2021; Lunsky et al., 2021; Zarei et al., 2022) and 6 studies had practice dairies (Atreya et al., 2018; Lange, 2020; Stjernsward & Hansson, 2017, 2018, 2020; Zarei et al., 2022). The duration of online interventions was 8 weeks for 6 studies (Atreya et al., 2018; Dragomanovich et al., 2021; Llaneza et al., 2022; Stjernsward & Hansson, 2017, 2018, 2020), 6 weeks for one study (Lunsky et al., 2021), and 4 weeks for another study (Lange, 2020).
Enablers of Online Mindfulness Practice
Three descriptive themes derived for enablers included (1) self-motivation, (2) positive experience of meditation, and (3) program structure and delivery.
Self-motivation
Self-motivation can be defined as a complex psychological process, involving how learners’ subjective beliefs and perceptions impact on their choices, effort, and persistence in achieving their goals (Bakhtiar & Hadwin, 2022; Berliner & Calfee, 2004; Eccles & Wigfield, 2002). To provide better support for the care recipient was noted as a motivator to participate in online MBI in 3 studies (Atreya et al., 2018; Dragomanovich et al., 2021; Stjernsward & Hansson, 2017). To focus/train/organise thoughts was cited as an enabler to participate in 2 studies (Atreya et al., 2018; Dragomanovich et al., 2021). Some participants joined the program due to their curiosity, whilst others participated to learn a new skill (Atreya et al., 2018; Dragomanovich et al., 2021). In one study, participants viewed mindfulness as a fashionable trend (Stjernsward & Hansson, 2020), thus prompting their participation. Three studies described the participants’ desire to participate in the intervention being driven, in part, by a desire to support in research in carer wellbeing (Atreya et al., 2018; Stjernsward & Hansson, 2017, 2020). Some participants noted that participating in a research study with a deadline was a positive influence to continue with the interventions (Stjernsward & Hansson, 2017).
Positive Experience of Mindfulness
Previous positive experience of meditation encouraged participants to undertake online MBI in 4 studies (Atreya et al., 2018; Lange, 2020; Stjernsward & Hansson, 2017, 2020). Participants from a study carried out to determine barriers and enablers of online mindfulness for informal carers of older adults with cognitive impairment reported that skills including breathing exercises, present moment awareness, and compassion helped them to reduce stress in their daily lives and thus encouraged adherence to online MBI programs (Llaneza et al., 2022). Some participants reported learning practical and meaningful skills from online MBI to empower them with better coping in the future (Lunsky et al., 2021). In addition, participants reported that having coping strategies available on their personal mobile device was helpful as they were able to access support right after a stressful period or at a regular scheduled time (Llaneza et al., 2022). In one study, participants experienced online MBI as a coping tool for stress, which in turn enhanced their wellbeing (Stjernsward & Hansson, 2017). They noted that they managed to reflect on a situation and not to be overwhelmed by strong emotions.
Participants also observed “thoughts come and go”, recognising the consequences of their actions, and choosing to either act upon or let go of a situation in a strategic way (Stjernsward & Hansson, 2017). Similar findings were reported in another study, where participants were more aware of their feelings and re-centred themselves using mindfulness exercises (Dragomanovich et al., 2021). The study was conducted to evaluate the feasibility and acceptability and estimate the efficacy of an 8-week online MBI program among informal carers of metastatic cancer patients. Participants in one study experienced reduced physical pain resulting from long-term stress when practicing online MBI, which in turn enhanced their health and wellbeing (Stjernsward & Hansson, 2017). In the same study, participants reported reduced anxiety. This study was conducted to explore the value and usability of an 8-week online MBI for informal carers of a person with mental and somatic health problems.
Four out of nine study participants experienced improved sleep, enabling them to continue practices (Atreya et al., 2018; Dragomanovich et al., 2021; Stjernsward & Hansson, 2017, 2018), whilst giving them an opportunity to self-care (Lange, 2020; Stjernsward & Hansson, 2017, 2018, 2020). Some participants recognised the training as an opportunity to look after their own needs, considering this as a valid excuse to take time off from caring (Stjernsward & Hansson, 2020). Further, participants valued to be connected with others in similar situations (Lunsky et al., 2021; Zarei et al., 2022). Participants from a study carried out to evaluate the feasibility and effectiveness of online mindfulness among informal carer of people with dementia reported to continue using the program as it addressed their needs (Zarei et al., 2022).
Program Structure and Delivery
Seven out of nine studies reported flexible and accessible interventions as an enabler for participating in online MBI (Lange, 2020; Llaneza et al., 2022; Lunsky et al., 2021; Stjernsward & Hansson, 2017, 2018, 2020; Zarei et al., 2022). Interventions were available for the participants to access at their own convenience (Stjernsward & Hansson, 2017). Participants noted that accessibility from home was especially beneficial when home bound with care recipients. Participants from another study also noted that having the app in their personal device and being able to use it according to their personal schedule, mood, and time preferences were motivators of using the intervention (Llaneza et al., 2022). Support from the research team members was reported as an enabler in 2 studies (Stjernsward & Hansson, 2017, 2020). Weekly email reminders with contact information for researchers for enquiries and technical support were motivators to continue the interventions (Stjernsward & Hansson, 2020). In one study, parents of adolescents and adults with autism noted a closed Facebook page as an enabler as it allowed them to access missed sessions and make connection with parents who have similar challenges (Lunsky et al., 2021).
Barriers to Mindfulness Practices
Three descriptive themes derived for barriers included (1) lack of self-motivation, (2) external factors preventing participation, and (3) program structure and delivery.
Lack of Self-motivation
Lack of self-motivation was identified as a significant barrier to mindfulness practice in 6 studies (Lange, 2020; Llaneza et al., 2022; Lunsky et al., 2021; Stjernsward & Hansson, 2017, 2018, 2020). Reasons for lack of motivation included low mood, inability to focus, lack of interest in using the app (Llaneza et al., 2022), procrastination (Lange, 2020; Stjernsward & Hansson, 2017, 2020), forgetfulness, difficulty in establishing new habits (Stjernsward & Hansson, 2017, 2020), and a lack of self-discipline (Stjernsward & Hansson, 2017). Some participants also viewed the program as a stressor which hindered their participation (Lange, 2020; Stjernsward & Hansson, 2017, 2020). They reported being behind with the program schedule and struggling with daily chaos. Some participants reported MBI training as another stressful demand in their daily life, noting an inability to complete the training within the given schedule, which in turn generated stress for them (Stjernsward & Hansson, 2020). Similarly, unmet expectations from the program also negatively influenced participation in the program (Stjernsward & Hansson, 2020).
External Factors Preventing Participation
All studies identified external factors as barriers to participation (Atreya et al., 2018; Dragomanovich et al., 2021; Lange, 2020; Llaneza et al., 2022; Lunsky et al., 2021; Stjernsward & Hansson, 2017, 2018, 2020; Zarei et al., 2022). Life circumstances such as carers’ health issues (Dragomanovich et al., 2021; Lange, 2020) and advanced age were indicated as barriers to participation (Lange, 2020). All studies identified time constraints as a barrier. These time constraints included health deterioration of the care recipient (Stjernsward & Hansson, 2020), providing medical care (Dragomanovich et al., 2021), and supporting the daily activities including taking them to medical appointments (Lange, 2020; Llaneza et al., 2022). Training that generated negative feelings was another barrier to participation (Stjernsward & Hansson, 2017, 2018, 2020). Feelings such as anxiety and stress were identified as factors by one participant who was in crisis (Stjernsward & Hansson, 2020). Some participants noted that their environment was not suitable for training (Stjernsward & Hansson, 2017, 2020).
Program Structure and Delivery
Participants in 2 studies reported difficulty in understanding or following the program instructions (Atreya et al., 2018; Stjernsward & Hansson, 2020). Some participants had trouble understanding exactly what was expected of them, which induced a sense of insecurity as to whether they were doing the training properly and if they were gaining its benefits (Stjernsward & Hansson, 2020). Two carers (n = 20) from another study reported that they had trouble understanding the instructions or content (Atreya et al., 2018). The study was conducted to assess feasibility, acceptability, and preliminary efficacy of an online MBI among patients with colorectal cancer and their informal carers. Technology issues were identified as a barrier in 4 studies (Atreya et al., 2018; Dragomanovich et al., 2021; Lange, 2020; Stjernsward & Hansson, 2020). One participant experienced computer problems with website issues and inaccessible content (Lange, 2020). This study investigated the feasibility and acceptability of online MBI comprising of 15 informal carers of stroke survivors (Lange, 2020). Belonging to the control group also acted as a barrier in one study, meaning participants had to wait long periods for exposure to the online MBI (Stjernsward & Hansson, 2020).
Relationship of Enablers and Barriers
Several concepts were identified for each of the enablers and barriers. These concepts were related to each other within and between the descriptive themes. Lack of self-motivation and external factors preventing participation can be interrelated due to their dependability with each other. For instance, care recipient illness may lead to procrastination in participating in online MBI. Program structure and delivery can positively or negatively be interrelated with remaining enablers and barriers. A conceptual map related to this is presented in Fig. 2.
Discussion
This review has identified the potential enablers and barriers to participating in an online MBI for informal carers. Though earlier reviews have synthesised evidence of some of these enablers and barriers among other populations (Guay et al., 2017; Linardon & Fuller-Tyszkiewicz, 2020; Marks et al., 2022; Winter et al., 2022), this review added to the existing knowledge by applying a systematic synthesis of evidence of enablers and barriers in all studies of online MBI specific to the informal carer population. The review identifies that online delivery of MBI programs can be a suitable mode to provide support for informal carers who may not be capable of attending face-to-face MBI programs.
This review identified self-motivation as an enabler for participating in online MBI. Similarly, previous studies have identified that carer motivation can be influenced by their perceptions, meanings and experiences, cultural values, beliefs, spiritual beliefs, illness beliefs, and socialisation (Zarzycki et al., 2023). This review revealed that previous positive experiences of mindfulness were a key enabler for participation in online MBI programs (Atreya et al., 2018; Lange, 2020; Stjernsward & Hansson, 2017, 2020). This finding is in keeping with a previous study conducted by Guay et al. (2017), which reported interventions tailored for behavioural change can have a positive effect on the psychological wellbeing of informal carers.
In contrast, identified barriers related to lack of self-motivation for participating in an online MBI have also been well documented in previous studies. Issues such as individual characteristics, viewing the program as a stressor, and unmet expectations of the program were discussed. Some of these findings have been reported in a previous systematic review which investigated the engagement strategies to improve participant adherence and retention in online mindfulness programs. It was identified that participants with poorer psychological wellbeing were more likely to drop out and disengage with interventions (Winter et al., 2022). Another study also identified that rumination and worry can hinder the participant retention rate in online MBI (Banerjee et al., 2018).
Aligning with our findings, difficulty understanding the program structure has been reported as a barrier in a previous study of online MBI for cancer patients (Compen et al., 2017). Saleem et al. (2021), in their study of understanding engagement strategies in online interventions, suggested some mitigation strategies such as sending reminders to participants, including colourful pictures, visual content, large colourful icons, and easy-to-understand content. Similarly, the broader literature has also identified negative effects of the training as a barrier for MBI support (Britton et al., 2021; Taylor et al., 2022). A systematic review was conducted to identify adverse effects of meditation interventions and mind-body practices, including 61 studies divided commonly reported negative effects from meditation interventions into 2 categories: mental distress and somatic distress (Taylor et al., 2022). Britton et al. (2021) have shown that MBI practices can be associated with transient distress and negative impacts on participants, with mild to severe levels of depression and persistently high levels of negative affect. Therefore, it is recommended that facilitators are aware of this risk and identify potential areas that require monitoring and intervention to maximise the safety and efficacy of MBI (Britton et al., 2021). Thus, creation of a strategic approach and clear protocols for distress management align with goals that are essential to safe interaction of participants with online MBI (Taylor et al., 2022).
This review has identified the relationship between program structure and delivery and external factors preventing participation (Fig. 2). Similar to our findings, previous studies have also identified competing priorities, programs not meeting participant needs, and lack of technical skills, time, and motivation (Boele et al., 2018; Moscato et al., 2019; Piil et al., 2015; van der Linden et al., 2018) as barriers to online MBI. It is also important to recognise here the relationship of sample characteristics for participating in web-based interventions including socio-economic background, education, and perceived health, as they can impact the adherence (Wu et al., 2022).
It is well known that co-design and meaningful engagement of end-users at all aspects of intervention development impacts on the outcomes of a project (Slattery et al., 2020; Talevski et al., 2023). In the current review, 2 studies incorporated advisory committee input for developing online interventions (Atreya et al., 2018; Dragomanovich et al., 2021). Co-design of internet-based interventions is known to be complex, as it involves interaction between researchers, users, and software developers (Thabrew et al., 2018). However, this is a good strategy to employ when developing online MBI within the informal carer population. Carer peer groups can also be involved with online MBI development, as carers are more likely to connect with other carers to share their experiences and knowledge (Schirmer et al., 2022). Solutions created for informal carers need to be internally motivating than decided for them (Hudson, 2013). Therefore, involving informal carers in the development process of online MBI may increase commitment to complete activities as they know what works best and what to include as they have lived experience of being a carer. Incorporating stakeholders to introduce online MBI and active governmental support for alternative interventions to improve health and wellbeing of informal carers are much needed. There is an opportunity for online MBI to be designed and adapted to meet the needs of informal carers, supporting access, and enabling their participation.
The integration of theoretical frameworks has been suggested when designing interventions to enhance retention rates of participants. One such framework is the Theoretical Domain Framework (TDF) (Michie et al., 2005), which explores implementation problems, and seek to better understand behaviour-change processes in the application of evidence-based care (Francis et al., 2012). This framework is comprised of 12 key constructs relevant to changing the behaviour of consumers (Michie et al., 2005). The TDF has been widely used by health professionals and investigated for further application and key developments (Francis et al., 2012; Phillips et al., 2015; Sarmast et al., 2014). Identified self-motivation and positive experience of mindfulness are related to one of the domains from the framework which is motivation and goals. Program structure and delivery and external factors preventing participation are related to environmental contexts and the resources domain (Michie et al., 2005). We have explored the relationships of the domains and how it impacts on participant engagement through the concept map in this study. Hence, the current review has so far identified only two aspects of the TDF. This acknowledgement could lead to future studies investigating the influence of the relationship between remaining domains.
Limitation and Future Research
There are some limitations to this review. We acknowledge that there were limitations of the terms used; however, we consulted with a health librarian to ensure that the current search terms provided an exhaustive approach to our search strategy. As a result, a comprehensive search was conducted across ten databases in total: eight health databases and two comprising grey literature. A hand search of relevant literature was also conducted. Due to the dearth of literature exploring the enablers and barriers of MBI for informal carers, no study was excluded during appraisal of methodological quality. Secondly, the findings were mainly qualitative as data were mainly extracted from qualitative findings, free text answers, and recruitment. Program attrition rate was varied between studies and high attrition was noted in most studies. This was also a limitation when interpreting findings. To establish trustworthiness, the research process was reported in detail. To enable transparency and to preserve the context for the evaluation of the reader, each study was reported in detail, according to the aim, participants, online intervention, data collection, analysis, findings, and comments related to enablers and barriers.
This systematic review has explored and synthesised evidence to provide a comprehensive understanding of enablers and barriers of online MBI for informal carers. The findings provide evidence of the enablers and barriers that should be considered when developing online MBI for informal carers to promote their participation. Developing co-designed carer-focused online MBI interventions is of vital importance to reduce the carer burden and enhance carer wellbeing. The effects of the identified enablers and barriers to participation in online MBI should be further researched. This would provide further evidence about enablers and barriers by engaging stakeholders in the process, so that programs can be developed in response to the needs of informal carers and promote their engagement with these interventions.
