Abstract

This study was designed to document the development of nurses’ affective commitment to their occupation and organization during the first five years of their career, as well as the connections between these two types of commitment trajectories. We also considered the associations between these early trajectories, nurses’ levels of psychological need satisfaction, and the quality of their early socialization. We finally investigated the implications of these trajectories for nurses’ work satisfaction, psychological distress, somatization, and patient care quality. Relying on a sample of 659 newly registered nurses (Mage = 26.8; 88% females) measured four times over a two-year period, we relied on growth mixture analyses to assess the shape of their commitment trajectories defined as a function of tenure. These analyses revealed four profiles, similar across targets of commitment: High, Moderate, Low and Increasing, and Average/Low and Decreasing. For both targets, higher levels of commitment were anchored in more stable trajectories, and with better functioning across outcomes. Need fulfilment and socialization experiences helped drive more desirable trajectories and provided short-term boosts in commitment. Overall, we found more similarities than differences between both forms of commitment, and noted that nurturing one type of commitment seemed to help develop the other.

Notes

  1. We adopt the labels proposed by Houle et al. (2022) rather than those proposed by Solinger et al. (2013) as they better differentiate between initial levels and change over time, as well as to simplify comparison across studies (Meyer & Morin, 2016).

  2. We first estimated a similar sequence of models using demographic controls (i.e., sex, age, part-time vs full-time, permanent vs temporary, level of education, and organizational tenure) to check if their inclusion was needed. Results, reported in Table S8 of the online supplements, support the lack of effect of these variables.

  3. The profile indicators (the repeated measures of occupational commitment) are factor scores estimated in standardized units (M = 0, SD = 1) saved from a longitudinally invariant measurement model.

  4. Conclusions about time-specific differences across profiles came from the examination of the 95% confidence intervals around the estimated trajectories obtained using Mplus’ LOOP PLOT function (Morin et al., 2020).

Data Transparency

The dataset used in this study was initially collected as part of a study specifically focused on motivation and was utilized in three previous publications. Study 1 is a cross-sectional variable-centered study looking at the role of motivation as a mediator of the associations between need satisfaction and psychological functioning. Study 2 is a person-centered study focusing on the stability on multidimensional motivational profiles across two time points. Study 3 is a person-centered study focusing on longitudinal trajectories of a global indicator of motivation using all four time points. In contrast, the current study focused on trajectories of affective organisational and occupational commitment across all time points but, rather than estimating these trajectories as a function of the time of measurement (thus essentially ignoring the effects of tenure), we estimated them as a function of nurses’ tenure, which allowed us to directly represent their onboarding (at career start) trajectories. We also note that, although some variables are used in more than one study, very often the way these variables are operationalized differ from one study to the other.

Summary of Hypotheses and Results

 

Hypotheses

Results

Support

 

Hypotheses about the shape of trait-like commitment trajectories

H1

Individual trajectories of affective commitment to the organization should match one of the following five profiles: Low, Moderate, High, Increasing, and Decreasing

Four organizational commitment profiles followed High, Moderately High, Low and Increasing, and Average and Decreasing trajectories

Full support

H2

Individual trajectories of affective commitment to the occupation should match one of the following five profiles: Low, Moderate, High, Increasing, and Decreasing

Four occupational commitment profiles followed High, Average, Low and Increasing, and Low and Decreasing trajectories

Full support

H3

Organizational commitment levels will differ more within and less across profiles than occupational commitment levels

Initial levels of organizational commitment presented almost twice as much within-profile variability as initial levels of occupational commitment. As expected, they also displayed less variability across profiles

Full support

H4

Most nurses will belong to matching profiles of organizational and occupational commitment trajectories (especially for the profiles with the highest and lowest trajectories), while a minority of nurses will belong to profiles characterized by distinct organizational and occupational commitment trajectories

Trait-like organizational and occupational commitment levels evolved in a similar manner for most nurses. This was especially true for those with low or high levels of commitment, while average levels of commitment to one target were less frequently linked to matching levels on the other target

Full support

 

Hypothesis pertaining to state-like deviations from trait-like trajectories of commitment

H5

Profiles with higher trait-like levels of affective commitment to the organization or occupation will be characterized by smaller state-like deviations (i.e., smaller time-specific residuals) around their trait-like trajectory, and vice versa

Profiles with by higher trait-like levels were accompanied by smaller state-like deviations. Increases in occupational commitment were more stable than increases in organizational commitment

Full support

 

Predictors effects on trait-like commitment trajectories

 

H6a

Higher global levels of need fulfilment will be associated with membership into profiles characterized by higher, and increasing, levels of affective commitment to the organization and occupation

Global need fulfilment increased membership into the High profile relative to the Low and Increasing organizational and occupational commitment profiles, and to the Low and Decreasing occupational commitment profile. Effects were stronger for the occupation than the organization

Partial support

H6b

Higher global levels of need fulfilment will be associated with within-profile trajectories characterized by higher levels of affective commitment to the organization and occupation, and with more pronounced increases in these levels

Global need fulfillment was associated with higher initial levels of organizational commitment and with a slight decrease over time in these levels. No within-profile associations found for occupational commitment

Partial support

H7a

The extent to which each specific need is fulfilled beyond global levels of need fulfilment will be associated with differentiated positive effects on profile membership

Autonomy and relatedness increased membership into the High occupational commitment profile relative to all others. Autonomy and competence increased membership into the High organizational commitment profile relative to the Average and Decreasing profile. Autonomy increased membership into the Moderately High versus the Low and Increasing organizational commitment profile. Relatedness increased membership into the High organizational commitment profile relative to the Low and Increasing one

Full support

H7b

The extent to which each specific need is fulfilled beyond employee’s global levels of need fulfilment will be associated with differentiated positive effects on within-profile trajectories

Competence was associated with a slight increase in organizational commitment

Partial support

H8a

Higher global levels of socialization will be associated with membership into profiles characterized by higher, and increasing, levels of affective commitment to the organization and occupation

Global socialization increased membership into the High relative to all other occupational and organizational commitment profiles (stronger for occupational commitment). These levels increased membership into the Moderately High relative to the Average and Decreasing organizational commitment profile

Partial support

H8b

Higher global levels of socialization will be associated with within-profile trajectories characterized by higher levels of affective commitment to the organization and occupation, and with more pronounced increases in these levels

No within-profile effect of global socialization was found

No support

H9a

Levels of learning/internalization specific to the organization will be associated with larger positive effects on profile membership and within-profile trajectories for organizational commitment

Organizational internalization increased membership to the High organizational commitment profile relative to the Average and Decreasing profile but had no effect on occupational commitment profiles and on within-profile trajectories. Organizational leaning had no effect

Partial support

H9b

Levels of learning/internalization specific to the tasks will be associated with larger positive effects on profile membership and within-profile trajectories for occupational commitment

Task internalization increased membership into the High relative to Low and Increasing and Low and Decreasing occupational commitment profiles, as well as into the Moderate relative to Low and Decreasing occupational profiles. Task internalization had no effect in relation to organizational commitment profiles and trajectories. Task learning had no effect

Full support

H10

Levels of internalization specific to the tasks, organization, and social relationships will be associated with larger effects on profile membership and within-profile trajectories

Beyond effects reported for H8a, H8b, team learning decreased membership in the High organizational profile relative to the Moderately High profile, whereas team internalization had the opposite effect. Team internalization increased membership into the High organizational profile relative to the Low and Increasing profile. In total, there were 6 effects of internalization on profiles, 1 (unexpected) effect of learning on profiles, and no within-profile effect of learning or internalization

Partial support

 

Predictors effects on state-like deviations from trait-like trajectories

 

H6c

Higher global levels of need fulfilment will be associated with more positive time-specific (state-like) increases in levels of affective commitment to the organization and occupation

Global need fulfillment was related to time-specific increases in organizational and occupational commitment (stronger for organizational commitment)

Full support

H7c

The extent to which each specific need is fulfilled beyond global levels of need fulfilment (i.e., imbalance) will be associated with differentiated positive effects on time-specific deviations

Autonomy and relatedness were related to time-specific increases in organizational and occupational commitment (stronger for organizational commitment). Competence was related to time-specific increases in occupational commitment

Full support

H8c

Higher global levels of socialization will be associated more positive time-specific (state-like) increases in levels of affective commitment to the organization and occupation

Global socialization was related to time-specific increases in organizational and occupational commitment (stronger for organizational commitment)

Full support

H9a

Levels of learning/internalization specific to the organization will be associated with larger positive effects on state-like deviations for organizational commitment

Organization internalization was related to time-specific increases in organizational commitment. Organization learning had no effect

Partial support

H9b

Levels of learning/internalization specific to the tasks will be associated with larger positive effects on state-like deviations for occupational commitment

Task learning and internalization were related to time-specific increases in occupational commitment

Full support

H10

Levels of internalization specific to the tasks, organization, and social relationships will be associated with larger effects on state-like deviations relative to specific levels of learning

No effect beyond those reported for H8a and H8b. In total, there were two effects of internalization for one effect of learning

Partial support

 

Outcomes

 

H11

Profiles characterized by higher initial levels of affective commitment to the organization or occupation will be accompanied by higher initial levels of work satisfaction and quality of care, and by lower initial levels of psychological distress and somatization

The highest work satisfaction and quality of care and the lowest somatization and psychological distress were observed in the High organizational and occupational commitment profiles. The lowest levels were observed in the Low and Decreasing occupational profile and the Average and Decreasing organizational profile

Full Support

H12

Profiles presenting increasing levels of affective commitment to the organization or occupation will be accompanied by steeper increases in levels of work satisfaction and quality of care, and by steeper decreases in levels of psychological distress and somatization relative to profiles with more static trajectories

The greatest increase in work satisfaction was in High and Low and Increasing profiles followed by the Moderately High profile. All profiles displayed a decrease in psychological distress (most pronounced in the Low and Increasing profiles). The largest decrease in somatization was in the Low and Increasing organizational profile, followed by the High and Moderately High profiles. Somatization decreased at the same rate for all occupational profiles. All profiles displayed increasing trajectory of quality of care (smallest increase in the High profiles)
