Purpose: Individuals receiving a temporary disability pension (TDP) should get the opportunity to return to work (RTW). The current study aims to determine the factors contributing to RTW. Methods: 453 individuals on TDP were interviewed at three measurement points (T1, T2 = T1 + approximately 7 months, T3 = T1 + approximately 17 months). Socio-demographics, psychological predictors, and current work status (maintained TDP, permanent disability pension, old-age pension, employed, or receipt of other benefits) were assessed. Results: Throughout the duration of the study, only four of the former temporary disability pensioners returned to work, and an additional seven made themselves available to the labor market. These were individuals who were younger, in TDP for a shorter period of time, and reported a higher RTW-intention. Higher RTW-intention was cross-sectionally associated with younger age, shorter TDP duration, and more positive outcome expectancies. Additionally, study participants who expected that medical rehabilitation would help them RTW were more motivated to RTW. An increase in RTW-intention over 17 months was related to younger age and better health. Conclusion: Personal factors such as self-efficacy and job-related variables appear less important for RTW than age and subjective health status. The observed RTW rates call for early support and tailored medical rehabilitation interventions that help individuals prevent functional limitations, overcome disability, and facilitate RTW. determined by work-related resources (Job Resources) and personal resources (Personal Resources), along with work-related challenges (Job Demands) [20]. Accordingly, Nigatu and colleagues [5] found that too many work-related challenges hinder work ability and RTW. This finding was also replicated by Haveraaen and colleagues [21], who found that decision-making, self-efficacy expectations, and social support are important for RTW.Various authors have pointed out that interventions should come to pass as early as possible [6,22,23]. Overland and colleagues [1] found that age was not correlated with RTW-intentions but that in general, RTW was associated with age [12]. Additionally, outcome expectancies (OE) related to incentives or gratification of work also appear to be important in RTW [24]. Moreover, individuals who managed to RTW were more likely to be previously employed [16,17,25] and had participated in a specialized rehabilitation during their DP [25]. In summation, the following research questions remain unanswered and the main aim of this work is to investigate them accordingly. The research questions are as follows:(1) What is the likelihood of returning to work (RTW) when receiving temporary disability pension (TDP) in Germany, and what are the characteristics of those who returned to work? (2) What is the relationship between RTW-behavior and RTW-intention? (3) Is there an association between the duration of TDP and RTW-intention? (4) What socio-demographic and psychological factors predict RTW-intention?Int.
