On the dark side of work: a longitudinal analysis using self-determination theory

ABSTRACT As the nature of work has changed in recent decades, employees are increasingly exposed to psychological demands in the workplace, which have associated consequences for employees, organizations, and society. Using self-determination theory, this study examined the dark side of work, in which frustration of basic psychological needs is associated with higher levels of work-related stress. In this model, work-related stress is associated with higher levels of somatic symptom burden, which in turn is associated with higher levels of emotional exhaustion, turnover intention, and absenteeism. Results of a longitudinal analysis using data from four time points over 15 months supported these predictions. Taken together, this study advances the literature towards an understanding of the (potential) detrimental impact that need-thwarting work contexts can have on employee wellness and work-related outcomes.

Changes in return to work among patients in vocational rehabilitation: a self-determination theory perspective

Abstract Purpose: The aim of the current study was to examine whether patient perceptions of autonomy support from the treatment team in a vocational rehabilitation program will be associated with change (increase) in need satisfaction, autonomous motivation, perceived competence, well-being, physical activity, and return to work (RTW), and whether the self-determination theory (SDT) Model of Health Behavior will provide adequate fit to the data. Method: A total of 90 participants were enrolled in a longitudinal study and completed measures at four time points over 15 months. Results: Participants reported increases in all variables, and in general these changes were maintained at six weeks post-rehabilitation and at 15 months post-baseline. As well, the SDT Model of Health Behavior provided adequate fit to the data. Conclusions: These results underscore the importance of health care practitioners’ providing support for their patients’ autonomy, competence, and relatedness to improve well-being, physical activity, and RTW in the context of vocational rehabilitation. Implications for Rehabilitation Vocational rehabilitation that emphasizes physical activity is associated with increases in patients’ well-being, physical activity, and return to work (RTW). It is important for health care practitioners to provide support for their patients’ autonomy, competence, and relatedness in the context of vocational rehabilitation, as doing so is associated with increases in patients’ autonomous motivation, perceived competence, and psychosocial outcomes.

Predicting dental attendance from dental hygienists’ autonomy support and patients’ autonomous motivation: A randomised clinical trial

Objective: To test the hypothesis that a Self-Determination Theory (SDT) intervention designed to promote oral health care competence in an autonomy-supportive way would predict change in caries competence relative to standard care. Further, to test the SDT process path-model hypotheses with: (1) the intervention and individual differences in relative autonomous locus of causality (RALOC) predicting increases in caries competence, which in turn would positively predict dental attendance; (2) RALOC negatively predicting dental anxiety, which would negatively predict dental attendance; (3) RALOC and caries disease referred to the dentist after an autonomy-supportive clinical exam directly positively predicting dental attendance; and (4) the intervention moderating the link between RALOC and dental attendance. Design: A randomised two-group experiment was conducted at a dental clinic with 138 patients (Mage = 23.31 yr., SD = 3.5), with pre- and post-measures in a period of 5.5 months. Results: The experimental model was supported. The SDT path model fit the data well and supported the hypotheses explaining 63% of the variance in dental attendance. Conclusions: Patients personality (RALOC) and hygienists promoting oral health care competence in an autonomy-supportive way, performance of autonomy-supportive clinical exams and reductions of anxiety for dental treatment have important practical implications for patients’ dental attendance.
