Laypeople do use sample variance: The effect of embedding data in a variance-implying story

When using sample data to decide whether two populations differ, laypeople attend to the difference between group means, but largely overlook within-group variability (Obrecht, Chapman, & Gelman, 2007 Obrecht, N. A., Chapman, G. B. and Gelman, R. 2007. Intuitive t-tests: Lay use of statistical information. Psychonomic Bulletin & Review, 14: 1147–1152.  [Google Scholar]). We show, first, that laypeople know about and use story-implied variability when making pairwise comparisons. Then we demonstrate that participants’ sensitivity to variance in a dataset is boosted when presented in a context that implies consistent variance information. Statistical data were couched in stories about electrical conductivity measurements obtained from element samples (low-variability category) or body weight measurements from samples of peoples (high-variability category). We manipulated, between participants, whether the data variance matched or mismatched the story-implied variability. Participants who received data in a matching context showed high sensitivity to variance, while those in the mismatching condition did not. Laypeople use statistical data to make reasonable inferences when those data are provided in a context that makes sense.     

Work engagement: Further reflections on the state of play

In this article we further reflect on the “state of play” of work engagement. We consider, clarify, and respond to issues and themes raised by eight preeminent work engagement researchers who were invited to respond to our position article. The key themes we reflect upon include: (1) theory and measurement of engagement; (2) state and task engagement; (3) climate for engagement versus collective engagement; (4) the dark side of engagement; (5) where job crafting may go wrong; and (6) moderators of the engagement–performance relationship. We conclude that engagement can sensibly be conceptualized as a positive and high arousal affective state characterized by energy and involvement; that there may be additional dimensions that might usefully be included; that we need to more fully understand the day-to-day and moment-to-moment temporal dynamics and implications of engagement; that a “climate for engagement” will influence individual and organizational outcomes; that although engagement is at heart a positive construct, the “dark side” of engagement needs to be acknowledged and understood; that “job crafting” provides a potentially powerful way for employees to manage their engagement; and that we need to gain a better understanding of the moderators that influence the way that engagement is related to performance. We also outline some practical implications that follow from our conclusions.     

Job crafting and job performance: A longitudinal study

In this three-wave study (N = 288), we examined whether job crafting intentions and work engagement led to actual job crafting behaviours and, in turn, to higher levels of prospective work engagement and job performance. We used the Job Demands-Resources model as a theoretical framework and defined job crafting as the self-initiated changes that employees make in their job demands and resources. One month after reporting their job crafting intentions, respondents rated their actual job crafting behaviours. Again one month later, they rated their levels of work engagement, in-role performance, and organizational citizenship behaviour towards individuals (OCBI). Results of structural equation modelling showed that job crafting intentions and work engagement significantly related to actual job crafting, which, in turn, related to higher levels of work engagement, while controlling for job characteristics. Results further showed that engaged employees performed better on their in-role tasks but did not perform more OCBIs. The findings suggest that employees can increase their own work engagement and job performance through job crafting.     

How psychological resources facilitate adaptation to organizational change

The purpose of this 1-year follow-up study among 580 police officers is to investigate whether identity-related resources are positively related to adaptive behaviour during times of organizational change. Combining the social identity perspective with resources theories, we hypothesized that leader–member exchange (LMX) and personal resources (meaning-making and organization-based self-esteem) are positively related over time. In addition, we hypothesized that resources captured before change implementation, show a positive relationship with adaptivity captured during change. Structural equation modelling analyses showed that LMX and personal resources were positively related. Further, all T1 resources were positively related to T2 adaptivity. The study emphasizes the importance of managing identity-related resources during turbulent times, in order to foster behavioural adaptation to change.     

Regulatory focus and the family–work interface: The role of regulatory fit between cohabiting partners

The aim of the present study was to examine the impact of regulatory focus in goal pursuit and regulatory fit between marital partners on family conditions and the family–work interface. We hypothesized that when both partners are high on promotion focus (fit) they experience higher developmental possibilities at home and have an increased likelihood of family-to-work facilitation (FWF). In addition, we hypothesized that when both partners are prevention focused (fit) they experience less home demands and less family-to-work conflict (FWC). In total, 131 working couples participated in the study. Each partner provided information about his/her own regulatory focus, perceptions of home demands and home developmental possibilities, and experienced FWF and FWC. Results of moderated structural equation modelling analyses largely supported our hypotheses since the interaction between partners’ promotion focus predicted the levels of home developmental possibilities and FWF, whereas the interaction between partners’ prevention focus predicted home demands in the expected direction. In conclusion, the fit between partners’ self regulatory styles can influence family life and, consequently, the impact of family on work.     

Thai Buddhism and well-being: an application of stress process theory

The purpose of this study was to explore how Buddhism is associated with well-being among Thai Buddhists via an application of stress process theory. Survey data were collected in 2012 from 314 Thai citizens and analysed with structural equation modelling to assess how the association between socio-economic status (SES) and well-being is mediated by stressors and resources, in particular, religious resources. The results reveal that low SES is associated with greater financial hardship and household crowding and lower sense of control, which in turn are associated with worse well-being. Furthermore, income is associated with happiness via belief in Dharma control, whereas education is associated with unhappiness via its negative association with public religiosity. Lastly, the positive influence of religious beliefs on well-being is contingent upon having a relatively high sense of control, whereas the positive influence of religious behaviours is contingent upon having a relatively low sense of control.     

Post-traumatic stress symptoms in mothers of children with leukaemia undergoing the first 12 months of therapy: Predictive models

The aim of this study consists in the measurement of psychological health and adaptation in mothers of children during the first 12 months of treatment for leukaemia and in the identification of possible early predictors. Ninety-four mothers were followed longitudinally at one week (T1), one month (T2), six months (T3) and 12 months (T4) post-diagnosis. The instruments used were: PTSD symptom checklist, BSI-18, Problem Scale, Ladder of life and an in-depth interview (EFI-C). Couple connectedness, family routine reorganisation, parental communication around the child's illness and trust in the medical care significantly increased from T1 to T4. Two models are proposed concerning possible predictors of mothers’ PTSS at T2 and at T3. Clinical suggestions are proposed on the basis of our empirical findings in order to plan informative, clinical and practical interventions for mothers of children under treatment for leukaemia.     

Bereavement and Religion Online: Stillbirth,Neonatal Loss,and Parental Religiosity

Stillbirth and neonatal death often trigger immense and long‐lasting grief in parents. These life‐altering losses both call upon and call into question parents’ religious beliefs and practices. This qualitative research examines the impact of stillbirth and neonatal death on parental religiosity, broadly conceived to include personal spirituality and any religious affiliation, including atheism. It examines religion online, a nontraditional but important social context for grief, especially regarding statistically rare tragedies such as stillbirth and neonatal death. Content analysis of postings on a hub website for “babyloss” parents yields four major themes: religious disorientation, religious reorientation, changed relationships with others, and a quest for meaning.     

Predictors for re-employment success in newly unemployed: A prospective cohort study

The aim of the present study was to examine which personal and situational factors affect reemployment success in persons in their first year of unemployment. In a prospective cohort study with a one-year follow-up, we investigated a sample of 3618 subjects who became unemployed. A survey was sent to all participants, including personal and situational factors, based on Wanberg's model, the Theory of Planned Behavior model and the Valence–Instrumentality–Expectancy model. Our results showed that ten key-factors predicted re-employment success in the first year after becoming unemployed. Knowing these factors, and in particular those which are amenable to change through any intervention program, may help to develop effective intervention strategies for those who facilitate reemployment in order to shorten the duration of unemployment.
