Special Issue: Character Strengths, Well-Being, and Health in Educational and Vocational Settings

The evidence-based promotion of well-being for individuals, institutions and societies is a common goal amongst quality of life researchers. Central research concerns in psychology can be described as what qualities from Bwithin^ a person, or what aspects of an individuum’s personality, contribute to health and well-being? Are there stable, interindividual differences that enable and promote flourishing? And what are necessary requirements (context factors) to bring forth the qualities from Bwithin^ a person? About 15 years ago Peterson and Seligman published their seminal book BCharacter Strengths and Virtues. AHandbook andClassification^ (Peterson and Seligman 2004). Combining cross-cultural, philosophical and theological traditions concerning the Bgood life^ with recent psychological inquiries they developed the Values in Action (VIA) classification of strengths and virtues. They identified 24 strength presumed to contribute to the fulfillments that constitute the good life, for oneself and for others. Character strengths are personality traits that are positively valued, and represent different routes to the superordinate virtues. Short descriptions of the character strengths are provided in Table 1. To be included in the VIA classification and considered a character strength, a potential strength had to fulfill a minimum set out of ten criteria, including being morally valued in its own rights; being traitlike, manifest in thoughts, feelings, and behavior, and somewhat consistent across situations and time; and being distinct from the other character strengths in the classification (Peterson and Seligman 2004). Thereby the authors reclaimed the study of character and virtue as legitimate topics of psychological research that has been neglected for a long time, since psychology focused on studying value-neutral personality traits (see for example Allport 1921).

To be included in the VIA classification and considered a character strength, a potential strength had to fulfill a minimum set out of ten criteria, including being morally valued in its own rights; being traitlike, manifest in thoughts, feelings, and behavior, and somewhat consistent across situations and time; and being distinct from the other character strengths in the classification (Peterson and Seligman 2004).
Thereby the authors reclaimed the study of character and virtue as legitimate topics of psychological research that has been neglected for a long time, since psychology focused on studying value-neutral personality traits (see for example Allport 1921). However, when we are interested in studying positive outcomes, in particular health and well-being, positive valued characteristicssuch as character strengthscan be expected to be much more relevant than presumably neutral concepts. This international special issue of Applied Research in Quality of Life focuses on the broad area of character strengths, well-being, and health research, also including (but not limited to) research and applications of well-being and positive psychological concepts in educational and vocational settings. The studies reported in this special issue are of high quality and diverse methodology. They span from cross-sectional studies based on large panel datasets (more than 15,000 participants) over longitudinal studies with more specific samples to the development of theory and application. All papers followed the standard peer-review process of the journal; papers authored or co-authored by the editors were assigned to action editors, who independently carried out the review process.
The  (2011) suggesting five dimensions of flourishing and well-being that encompass both subjective and eudemonic aspects, Wagner et al. (2018) demonstrated in a sample of over 5000 participants the robust relationships of character strengths with these different dimensions of well-being. Further, these relationships also hold when not relying only on self-ratings but also taking informantratings into account. Baumann et al. (2018) focus on life satisfaction in later life, in particular how several transitions specific for older people (e.g., retirement or being widowed) are linked to life satisfaction and character strengths. Based on data of over 15,000 older adults the authors conclude that character strengths might offer a starting point for strengths-based intervention programs to maintain, enhance, or prevent a decrease in life satisfaction in later life. Despite character strengths being seen as stable traits, they are also considered malleable due to cultivation or deliberate interventions. Accordingly, Gander et al. (2018) explored the stability and malleability of character strengths and their relations to well-being applying a longitudinal study with more than 1700 participants. Their results provide an important basis for intervention studies addressing the promotion of character strengths and well-being of individuals. The paper of Hofmann et al. (2018) focuses on one specific aspect of a virtuous character, humor, and examines its relationships to another desirable personal characteristic, mindfulness. The authors report three empirical studies in different settings including nearly 600 participants in total. Their core hypotheses proposed that mindfulness is positively linked to Blight^forms of humor and negatively linked to darker forms. Accordingly, Study 1 and Study 2 investigated the relationship between different aspects of humor and mindfulness. Additionally, in Study 3 the effects of a mindfulness intervention on humor were examined concluding that it might be fruitful to combine humor interventions and mindfulness interventions.
Udayar and colleagues (Udayar et al. 2018) broadened the scope by investigating character strengths not directly, but focusing on the development of the basic Bbig fived imensions of personality. Based on a cross-lagged-panel design over 4 years and data from more than 1300 individuals Udayar et al. (2018) demonstrate that perceived social support has positive effects on the development of these Bbig five^personality traits in middle adulthood. Because previous research showed that big five personality traits are related to character strengths their results hint towards not only the malleability of fundamental psychological traits but also character strengths by social support.
Well-being at work and in occupational settings is an important topic in real life what is well-reflected by its increased coverage in research, but also the mainstream media (Danna and Griffin 1999). Research on character strengths might allow for broadening the perspective and providing insights about what can go Bright^at the workplace, thereby not only preventing negative consequences, but also fostering positive outcomes, such as well-being, engagement, or a positive organizational climate. Thus, understanding factors contributing to well-being and health in the work and organizational setting considering the role of character strengths is a promising field for both research and application. Based on a sample of hospital physicians the paper by Huber et al. (2018) addresses the question whether the possession of certain character strengths is enough to enhance well-being at work or if the possibility to apply one's character strengths at work is mandatory to enhance well-being. Based on crosssectional and longitudinal data also from the field of hospital physicians the studies by Strecker et al. (2018) and Höge et al. (2018), identified condition-related antecedents of the applicability of individual signature character strengths at work and their relation to work engagement and well-being. Strecker et al. (2018) focused on task related work characteristics (e.g., autonomy, social support, learning demands) whereas Höge et al. (2018) addressed a specific subset of the organizational climate, the socalled Bsocio-moral climate^as possible antecedent. Also addressing condition-related effects on strength use at work and its positive outcomes, Meyers et al. (2018) demonstrate that organizational support for strength use at work is positively related to work engagement and contextual performance, and that this association is stronger among younger employees. Heintz and Ruch (2018) focus on a different fulfillment in life, namely the satisfaction derived from with one's work. They investigate the relationship between the 24 character strengths (and five strengths factors) with components of job satisfaction and overall job satisfaction in a general working population (N = 12,499) to identify the list of strengths that facilitate being satisfied with work in general. The authors argue that knowing which strengths are more important for specific working populations can help to develop and apply more effective strength-based interventions in the workplace, thereby improving positive and reducing negative work-related outcomes.
Littman-Ovadia and Freidlin (2018) focus in their work on the overuse and underuse of character strengths and which implications this may have towards flourishing, satisfaction with life, and psychopathology such as obsessive-compulsive disorder. In relation to this, Niemiec (2018) provides theoretical thoughts on six different functions of character strengths for flourishing in times of adversity and opportunity. These six functions provide a promising new framework for future research and practice. In her literature review Lavy (2018) critically addresses the potential of teaching character strengths at schools. In particular, she identifies obstacles to integrate such activities in the school curricula. However, she also adds a strong note of caution to the notion that character strengths are only and ultimately positive.
Finally, the methodology of measuring character strengths is essential to have reliable and valid data. The paper of Höfer et al. (2018) reports the psychometric properties of a German character strengths short form measure based on data from two independent samples. This special issue critically highlights the concept of character strengths in relation to well-being and provides new scientific evidence and a conceptual theoretical framework to further develop quality of life research from the perspective of Positive Psychology.
