Cycling strategies of young and older cyclists

This study concentrates on the cycling strategies of older cyclists (54–62 year olds) in comparison to young cyclists (20–30 year olds). While cycling in a safe laboratory set-up, controlled lateral perturbations are applied to the rear of the bicycle. Three possible strategies to keep balance are analysed for a young and older aged group: steering, lateral trunk movement and outward knee movement. Older subjects appear to rely more on knee movement as a control mechanism than young subjects. Furthermore, the frequency domain analysis revealed that the older adults need more effort to counteract high frequency perturbations. Increased inter-individual variation for the older adults subject group suggests that this group can be seen as a transition group in terms of physical fitness. This explains their increased risk in single-sided bicycle accidents (i.e. accidents involving the cyclist only). Therefore, older cyclists could benefit from improving the stability of cycling at lower speeds.     

A longitudinal person-centred approach to the job demands-control model

We used a longitudinal design and a person-centred methodology to test the strain and learning hypotheses of the job demands–control model among Finnish employees (n = 926), who were followed-up at three time points covering a period of 2 years (2008–2010). First, we identified longitudinal subgroups in demands and control across three measurement points. Second, we examined how these subgroups differed in strain (job exhaustion) and motivation-related outcomes (vigour at work, work–family enrichment). Growth mixture modelling revealed four subgroups: “stable high strain”, “stable low strain”, “increasing control”, and “decreasing control”. The stable high- and low-strain subgroups also differed in the outcomes studied (exhaustion, work–family enrichment) as suggested by the demands–control model. The findings also suggest that job control is subject to changes over time and that these changes are likely to be associated with changes in employee outcomes. Malleability of job control should be kept in mind in job stress interventions, likewise the fact that some employees suffer from chronic job stress.     

The consequences of job crafting: a three-wave study

This longitudinal study examined the consequences of job crafting on two important employee outcomes: psychological capital (PsyCap) as a work-related personal resource and work engagement as an indicator of employee well-being. The study also tested the reverse causation effects of PsyCap and work engagement on job crafting. It used a three-wave, three-month panel design to survey 940 employees from three European countries working in a broad range of economic sectors and occupations. The results of the cross-lagged longitudinal structural equation modelling demonstrated that job crafting predicted PsyCap and work engagement over time. No reverse causation effects were found. Overall, this study shows that when individuals proactively build a resourceful and challenging work environment for themselves, it can lead to diverse positive outcomes that are crucial to employee health and well-being. Employees should therefore be encouraged and be given the opportunity to craft their own jobs.     

The mitigating role of leader‒member exchange when perceiving psychological contract violation: a diary survey study among volunteers

Several scholars in the field of volunteering emphasized the pivotal role of psychological contract (PC) violation in explaining maladaptive behavioural reactions—such as counterproductive work behaviour (CWB)—of volunteers. Reactions to violation feelings are, however, interrelated and may intensify over time. Extending this dynamic perspective, we introduce momentary leader–member exchange (LMX) as a buffering social resource in the relationship between violation feelings and (1) CWB and (2) the likelihood to perceive a PC breach. Using weekly diary survey data from 247 volunteers (827 observations), we conducted a moderated multilevel zero-inflated Poisson regression analysis. As hypothesized, experiencing feelings of violation during one week related positively to CWB towards the organization (CWB-O), but not to CWB towards individuals (CWB-I) during the next week. Moreover, experiencing violation feelings during one week increased the likelihood to perceive a PC breach during the subsequent week. Finally, experiencing a high-quality LMX relationship effectively mitigated the positive relationship between violation feelings during one week and (1) CWB-O, and (2) the likelihood to perceive a PC breach during the next week. Our study highlights momentary LMX as an effective redressing mechanism in the relationship between violation feelings and undesirable employee outcomes.     

社会支持、主动反刍与创伤后成长的关系:基于汶川地震后青少年的追踪研究

本文以追踪研究的方式,在汶川地震后3.5年、4.5年和5.5年三个时间点,采用社会支持问卷、反刍问卷和创伤后成长问卷对汶川地震后245名中学生进行调查。通过建立交叉滞后模型,考察社会支持、主动反刍与创伤后成长的相互作用关系。结果发现,震后3.5年至5.5年间,社会支持对主动反刍和PTG的跨时间点预测作用不显著;主动反刍对PTG具有显著的跨时间点正向预测作用,但对社会支持的跨时间点预测作用不显著;震后3.5年的PTG对震后4.5年的主动反刍具有显著的跨时间点正向预测作用,但震后4.5年的PTG对震后5.5年的主动反刍的跨时间点预测作用不显著;震后3.5年和4.5年的PTG分别对震后4.5年和5.5年的社会支持的跨时间预测作用均不显著。     

工作恢复:重回良好工作状态的必由之路

工作恢复是指工作中精力消耗之后,个体生理和心理状态的恢复过程。工作恢复是个体补充消耗的生理和心理资源的过程,这一过程可用努力—工作恢复模型和资源保存理论加以解释。目前工作恢复研究多采用自我报告的日记研究法,探索心理剥离、放松、掌握经验和控制等工作恢复的心理过程,考察休整、非工作活动、员工所处社会环境等工作恢复的前因变量,并检验工作恢复对幸福感、健康、工作表现等结果变量的正向预测作用。研究表明,工作恢复有助于个体保持积极情感、提高工作业绩。今后需在工作恢复的测量指标和研究方法等方面改进研究设计,并在工作恢复的作用机制及干预等方面着力拓宽研究方向。     

Parent–child relationships and offspring’s positive mental wellbeing from adolescence to early older age

We examined parent-child relationship quality and positive mental well-being using Medical Research Council National Survey of Health and Development data. Well-being was measured at ages 13–15 (teacher-rated happiness), 36 (life satisfaction), 43 (satisfaction with home and family life) and 60–64 years (Diener Satisfaction With Life scale and Warwick Edinburgh Mental Well-being scale). The Parental Bonding Instrument captured perceived care and control from the father and mother to age 16, recalled by study members at age 43. Greater well-being was seen for offspring with higher combined parental care and lower combined parental psychological control (p < 0.05 at all ages). Controlling for maternal care and paternal and maternal behavioural and psychological control, childhood social class, parental separation, mother’s neuroticism and study member’s personality, higher well-being was consistently related to paternal care. This suggests that both mother–child and father–child relationships may have short and long-term consequences for positive mental well-being.     

Conversation on mental states at nursery: Promoting social cognition in early childhood

Despite growing evidence that conversation on inner states fosters gains in children’s social cognition, this mechanism has yet to be tested with toddlers. To address this gap, we examined whether an intervention based on conversing about mental states with small groups of 2-year-old children at nursery had a significant effect on toddlers’ theory of mind (ToM) and emotion understanding (EU). Participants were 68 children (M_age at pre-test: 29.9 months) who were assigned to either an experimental or a control condition. Measures of verbal ability, ToM and EU were administered at pre-test, post-test and follow-up stages. Over a one-month intervention, all children were read a series of brief illustrated stories. After listening to the stories, the experimental group (n = 34) was involved in conversations on mental states, whereas the control group (n = 34) was engaged in conversation regarding the material entities and actions featured in the storybook. The experimental group significantly outperformed the control group on measures of both ToM and EU, independently of gains in verbal ability. Furthermore, these positive effects remained stable over time. We discuss the theoretical and practical implications of these findings.     

Relationship Between Private Religious Activity and Physical Functioning in Older Adults

This study sought to further understand the relationship between physical functioning and use of private religious activity in older adults. Subjects were age 65 or older from urban and rural counties in North Carolina who participated in the Duke University Established Populations for Epidemiologic Studies of the Elderly (Duke/EPESE). A total of 3,851 subjects responded to a question that inquired about their use of prayer, meditation, or Bible reading in 1986. Their response was correlated to number of impairments in activities of daily living (ADLs) (n = 3,791). Subjects who indicated use of private religious activity either dailyor neverhad the greatest number of impairments. Those who prayed or meditated one time per weekhad the least number of impairments. This cross-sectional finding is explained in terms of both changes in private religious activity in response to increasing physical disability and changes in physical disability in response to private religious activity. Previous research has found that prayer is often used as an effective coping mechanism with various sicknesses and chronic conditions. Further studies are needed to examine older individuals' health over time and evaluate their use of private religious activity to see its impact over time on physical disability.
