BACKGROUND: Work in the industrial sector underlies deep structural changes triggered by demographic and societal transformations. These developments require tailored measures for maintaining employees' work ability by reacting to new demands and overcoming barriers in organizational implementation. Previous research lacks in considering practitioners' perspective in terms of tailoring effective interventions to the workplace conditions of blue-collar employees. OBJECTIVE: This study aims to enrich the understanding of work ability by using the job-demands-resources (JDR)-theory and the work ability house concept as basis and considering aspects of organizational measures' feasibility. METHODS: Data results from observations of the collaboration between occupational health professionals and supervisors on the shop-floor and n = 18 semi-structured interviews with different occupational health stakeholders. A participatory and qualitative approach characterizes this study. RESULTS: The study participants report on how increasing organizational demands of efficiency and uncertainty affect workability promotion of blue-collar employees. Furthermore, the findings imply aspects regarding feasible interventions. For designing effective interventions, specifically psychosocial aspects such as work intensification, job uncertainty, work-life-conflicts, and inter-personal trust need to be addressed. Measures need to be aligned better to the industrial setting with specific focus on decision-makers' interests and intra-organizational collaboration. CONCLUSION: Further research should investigate interrelationships between relevant psycho-social job demands and resources. Moreover, additional aspects, which are related to measures implementation in the organizational sphere, need to be identified. Practical implications connect organizational sciences with the workability theory and the job-demands-resources (JDR)-theory by focusing more on psychological work design and intra-organizational collaboration.

Applying socioemotional selectivity theory to the domain of health, we examined the interplay of social-cognitive predictors of physical exercise in two groups of people who perceived their remaining lifetime as either expansive or limited (based on subjective longevity ratings). Individuals (N = 370) who were prescribed physical exercise were assessed at discharge from orthopedic rehabilitation as well as 6 and 12 months later. Multigroup structural equation modeling showed differences in latent means, interrelations of predictors, and amount of explained variance. Individuals who perceived their time as limited reported a less favorable profile on social-cognitive variables and less exercise goal attainment. We give first insights on how health self-regulation differs in these groups, and we discuss avenues for intervention based on socioemotional selectivity theory. In contrast to chronological age, subjective life expectancy can be targeted by intervention.

In this study, we draw attention to time-competing activities and psychological variables as impeding or enabling factors of physical activity behavior in 55- to 70-year-old Germans. Cross-sectional data was used (n = 4,891). Results indicate that paid work has a negative relationship with sufficient physical activity. Persons who provide nursing care seem to be motivated to achieve sufficient physical activity behavior, but do not meet established recommendations. Active citizenship positively relates to higher physical activity levels. The investment of energy in life domains and a distinct internal locus of control characterize motivated underachievers. Those sufficiently physically active show higher values in conscientiousness. This suggests that time-consuming and strongly externally determined activities like nursing care and paid work hinder a sufficient level of physical activity, even if the motivation is existent. Active citizenship and physical activity seem to be linked processes. [ABSTRACT FROM AUTHOR]

Background: This study aimed to identify latent moderate-to-vigorous intensity physical activity (MVPA) and sedentary behavior (SB) trajectories in older adults participating in a randomized intervention trial and to explore associations with baseline social-cognitive predictors. Methods: Data were assessed at baseline (T0, participants were inactive or had recently become active), after a ten-week physical activity intervention (T1), and a second 24-week intervention phase (T2). Latent class growth analysis was used on accelerometer-assessed weekly MVPA and daily SB, respectively (n = 215 eligible participants). Activity changes within trajectory classes and baseline social-cognitive predictor differences between trajectory classes were analyzed. Results: A "stable insufficient MVPA" (n = 197, p for difference in MVPA level at T0 and T2 (pT0-T2) =.789, effect size (Cohen's d) =.03) and a "stable high MVPA" trajectory (n = 18, pT0-T2 =.137, d =.39), as well as a "slightly decreasing high SB" (n = 63, p for difference in SB (pT0-T2) =.022, d =.36) and a "slightly increasing moderate SB" trajectory (n = 152, pT0-T2 =.019, d =.27) emerged. Belonging to the "stable high MVPA" trajectory was associated with higher action planning levels compared to the "stable insufficient MVPA" trajectory (M = 5.46 versus 4.40, d =.50). Belonging to the "decreasing high SB" trajectory was associated with higher action self-efficacy levels compared to the "increasing moderate SB" trajectory (M = 5.27 versus 4.72, d =.33). Conclusions: Change occurred heterogeneously in latent (not directly observed) subgroups, with significant positive trajectories only observed in the highly sedentary.
