Crossover between work and home in dyadic partner relationships

This study aimed at providing insight into the processes underlying crossover between "work" and "home" in dyadic partner relationships. Specifically, we examined to what extent husbands' work demands (work load and overtime hours) and psychological health (fatigue and depressive symptoms) "cross over" to their wives' home demands (home load) and psychological health. These associations were investigated among three couple groups, based on wives' working hours (i.e., more than 20 hours per week, from 1 to 20 hours per week, and not engaged in paid work) (253 couples in total). All husbands worked for at least 35 hours a week. Three possible crossover mechanisms were hypothesized: (i) time-based, (ii) strain-based, and (iii) empathy-based crossover. The results partially supported mechanisms (i) and (ii): when husbands reported higher work load (mechanism i) and more psychological health complaints (mechanism ii), their wives experienced higher home load. The results further supported mechanism (iii) that wives' and husbands' psychological health were associated. It is concluded that crossover from husbands to wives may occur through various mechanisms.     

The role of psychological detachment in burnout and depression: A longitudinal study of Malaysian workers

The current study aimed to examine the role of psychological detachment in the relationship between working conditions and burnout and depression. First, the study proposed that job demands would increase burnout after four months but not depression. Second, it proposed that psychological detachment would moderate the impact of job demands and job resources on burnout and depression. Third, it was proposed that the interaction between job demands, job resources and psychological detachment would predict burnout and depression. The longitudinal study design involved 345 workers (at both Time 1 and Time 2). The hierarchical regression analysis showed that increasing psychological detachment reduced the negative relationship between physical demands and depression four months later. In contrast, high psychological detachment increased the negative association between emotional resources and burnout, but not between emotional resources and depression. Overall, this study, in its discovery of the impact of working conditions on psychological health, has made a new contribution to psychological detachment studies by using different sub-constructs of job demands and job resources (i.e., emotional and physical) with four-month gaps, as previous studies did not address the impact within this time frame.     

Accelerated muscle contractility and decreased muscle steadiness following sauna recovery do not induce greater neuromuscular fatigability during sustained submaximal contractions

Acute whole-body hyperthermia (WBH) increases blood markers concentration of stress, impairs motor drive to exercising muscles, and decreases resistance to neuromuscular fatigability. The functional natural residual consequences of WBH on neuromuscular functions remain unclear. We aimed to investigate the effects of residual WBH on voluntary and electrically induced ankle plantar flexor contractility properties, motor drive transmission (reflexes), muscle torque steadiness, resistance to neuromuscular fatigability, and markers of stress as the body temperature recovers naturally to normothermia. WBH was induced by Finnish sauna bathing in 16 apparently healthy young (24 ± 4 years) adult men. Motor performance was monitored before and 2 h after the sauna, and immediately after submaximal exercise (120 s at 50% of maximal voluntary contraction). Markers of stress were monitored before and 2 h after the sauna. Finnish sauna exposure induced moderate to severe WBH (rectal temperature, 38.5–39.6 °C). At 2 h after the sauna, rectal temperature had recovered to the preheating level (preheating 37.11 ± 0.33 °C versus postheating 37.00 ± 0.29 °C, p > .05). Post-sauna recovery was accompanied by slowed salivary free cortisol diurnal kinetics, whereas noradrenaline, dopamine, and serotonin did not persist into the 2 h recovery after the sauna. Although recovery to normothermia after a sauna led to a greater acceleration of muscle contractility properties and decreased muscle steadiness, sustained isometric submaximal contraction did not provoke greater neuromuscular fatigability.     

Driving demands,stress reactivity and driving behavior: An interactional approach

The aim of the present study was to investigate the role of driving demands, neuroticism, and their interaction when predicting driving behavior. More precisely, we strived to examine how driving behaviors (i.e., speeding, winding, tailgating and jerky driving) unfold across low and high driving demands and whether they are contingent on a personality factor that has previously been linked to stress reactivity. In a driving simulator, 50 participants with a valid driver’s license (56.6% female, age: M = 30.13, SD = 10.16) were exposed to driving scenarios of different levels of information processing and vehicle handling demands. Additionally, they filled-out a self-report questionnaire that measured their neuroticism. We found that driving behavior became safer in scenarios that were highly demanding in terms of information processing, while this pattern did not emerge with vehicle handling demands. Moreover, tentative support was found for the notion that individuals high in neuroticism are less able to adapt their behavior to higher information processing demands. The present study offers new insights on driving demands in a simulated driving context and points to the potential importance of exploring interactions between personality and situational factors when understanding driving behavior. Additionally, the results of the present study may be used to adapt driver’s education programs.     

Developmental trajectories of multisite musculoskeletal pain and depressive symptoms: The effects of job demands and resources and individual factors

Objective: To investigate developmental paths in multisite musculoskeletal pain (MPS) and depressive symptoms (DPS) and the effects of job demands (JD), job resources (JR), optimism and health-related lifestyle on these paths. We expected to find four trajectories – Low Symptoms, High Pain, High Depression and High Symptoms – and hypothesised that high JDs, low JRs, low optimism and adverse lifestyle predict belonging to trajectories with high symptom levels.

Design: Data on Finnish firefighters (N = 360) were collected in 1996, 1999 and 2009. The effects of JDs (mental and physical workload), JRs (supervisory relations, interpersonal relations, task resources), optimism and lifestyle (alcohol consumption, smoking, physical exercise, sleeping) on MPS and DPS were assessed. Latent class growth modelling and multinomial logistic regression were applied.

Results: Three trajectories emerged: Low Symptoms; High Pain; and High Depression. In a multivariable model, high mental workload (OR 2.9, 95% CI 1.5–5.5), poor interpersonal relations (2.6, 1.4–5.0), sleeping problems (2.7, 1.4–5.2) and low optimism (2.0, 1.0–3.7) predicted belonging to High Depression. Alcohol consumption (2.4, 1.4–4.1) and sleeping problems (2.1, 1.3–3.6) were related to High Pain.

Conclusions: Different developmental paths in MPS and DPS are possible. Partly different factors predict the development of pain and depressive symptoms.     

Who benefits the most from a gratitude intervention in children and adolescents? Examining positive affect as a moderator

This research addresses the notion that the compatibility of skills and task demands involved in an activity elicits flow-experiences that render the activity intrinsically rewarding. We applied two experimental settings designed to test the causal impact of a skills–demands compatibility on the emergence of flow and intrinsic motivation: a playful computer game (Experiment 1) and a knowledge task (Experiment 2). Results support the balance hypothesis and indicate that compatibility of skills and task demands results in a flow-experience, irrespective of the type of activity. This demonstrates the generalizability of flow-experiences across two qualitatively different types of activities. Going beyond prior research, the results of Experiment 2 reveal that flow-experiences foster the willingness to reengage in the activity in a free choice setting, which represents a behavioral measure of intrinsic motivation.     

Work happiness among teachers: A day reconstruction study on the role of self-concordance

Self-concordant work motivation arises from one's authentic choices, personal values, and interests. In the present study, we investigated whether self-concordant motivation may fluctuate from one work-related task to the next. On the basis of self-determination theory, we hypothesized that momentary self-concordance buffers the negative impact of momentary work demands on momentary happiness. We developed a modified version of the day reconstruction method to investigate self-concordance, work demands, and happiness during specific work-related tasks on a within-person and within-day level. In total, 132 teachers completed a daily diary on three consecutive work days as well as a background questionnaire. The daily diary resulted in 792 reported work activities and activity-related work demands, self-concordance, and happiness scores. Multilevel analysis showed that—for most work activities—state self-concordant motivation buffered the negative association of work demands with happiness. These findings add to the literature on motivation and well-being by showing that the levels of self-concordance and happiness experienced by employees vary significantly on a within-day level and show a predictable pattern. We discuss theoretical and practical implications of the findings to increase employees' well-being.     

Measuring adaptability demands of jobs and the adaptability of military and civilians

Jobs within the military and in civil society differ in character and requirements. It is assumed that differences in job types both within civil and military domains require different dimensions of adaptability competency. The present study investigates this assumption. The Dutch Adaptability Dimensions And Performance Test (D-ADAPT) was used to measure both the adaptability demands of jobs, and of self-assessed adaptability competency of employees. In addition, the predictive value of certain personality traits (openness, neuroticism, and conscientiousness) and other relevant personal characteristics (cognitive flexibility, learning goal orientation) on various adaptability dimensions was explored. Military personnel were found to estimate their adaptability competency as higher than civilians did. With respect to the civilian jobs, the adaptability demands varied across job types. This was not found in the set of military jobs, possibly due to a smaller variety of jobs included. This study also shows that a variety of personal characteristics predict different dimensions of adaptability. Cognitive flexibility was found to be the best predictor for adaptability in general. Openness turned out to be a good predictor within the civilian group, whereas neuroticism was a better predictor within the military group. Results of this study contribute to a better understanding of work adaptability and influencing personality characteristics. Practical implications for selection and training of personnel can be derived, based on the acquisition of adaptability competency that matches the type of job.
