The relationships of change in work climate with changes in burnout and depression: a 2-year longitudinal study of Chinese mental health care workers

Mental health care workers face heavy emotional demand and are prone to work burnout. Work burnout has been associated with poor mental health and work climate, which refers to individual perceptions about work setting. The purpose of this study was to examine whether intra-individual changes in work climate were associated with intra-individual changes in burnout and depression over two years. The present sample included Chinese mental health care workers (N = 312; mean age = 38.6, SD = 9.9) working in a psychosocial rehabilitation institution. The participants completed questionnaires on work climate, work burnout and depression at seven time points across two years. Parallel process latent growth modeling was used to analyze the associations of change between work climate and burnout and depression. Work climate displayed a logarithmic decreasing trend while burnout and depression displayed logarithmic increasing trends over two years. Baseline levels of work climate were negatively and moderately associated with baseline levels of burnout and depression (r = ?.44 to ?.60, p < .01). Changes in work climate were negatively and moderately associated with change in burnout (r = ?.43, p < .01) and change in depression (r = ?.31, p < .05). Change in burnout was positively and strongly associated (r = .58, p < .01) with change in depression. The current results support temporal relationships among changes in work climate, burnout and depression across time. Practical implications for future preventive work in burnout interventions were discussed within this population.     

Constraints on Multiple Object Tracking in Williams Syndrome: How Atypical Development Can Inform Theories of Visual Processing

The ability to track moving objects is a crucial skill for performance in everyday spatial tasks. The tracking mechanism depends on representation of moving items as coherent entities, which follow the spatiotemporal constraints of objects in the world. In the present experiment, participants tracked 1 to 4 targets in a display of 8 identical objects. Objects moved randomly and independently (moving condition), passed behind an invisible bar (occluded condition), or momentarily disappeared by shrinking (implosion condition). Scholl and Pylyshyn (1999) found that adults can track entities under the moving and occluded conditions, but not under implosion. This finding suggests that the tracking mechanism is constrained by the spatiotemporal properties of physical objects as they move in the world. In the present study, we adapt these conditions to investigate whether this constraint holds for people with severe spatial impairments associated with Williams syndrome (WS). In Experiment 1, we compare the performance of individuals with WS and typically developing (TD) adults. TD adults replicated Scholl and Pylyshyn’s findings; performance was no different between the moving and occluded conditions but was worse under implosion. People with WS had reduced tracking capacity but demonstrated the same pattern across conditions. In Experiment 2, we tested TD 4-, 5-, and 7-year-olds. People with WS performed at a level that fell between TD 4- and 5-year-olds. These results suggest that the multiple object tracking system in WS operates under the same object-based constraints that hold in typical development.     

Life Events and Social Rhythms in Bipolar Spectrum Disorders: A Prospective Study

This study examined the social zeitgeber theory, which suggests that affective symptoms are caused by life events disrupting vulnerable individuals’ social and circadian rhythms. Undergraduate participants were selected based on a 2-phase screening process, including a semistructured diagnostic interview. The final sample consisted of 101 bipolar spectrum participants and 100 demographically matched normal controls. Participants who completed up to 3 follow-up visits, approximately every 4 months, as part of a longitudinal study were included in the current study. Life events did not predict social rhythm regularity and social rhythm regularity inconsistently predicted affective symptoms. However, life events, particularly social rhythm disruption (SRD) events, did predict depressive symptoms and episodes, and less consistently predicted hypo(manic) symptoms and episodes. Thus, the current study obtained mixed support for social zeitgeber theory.     

Evaluating Pastoral Effectiveness: To Measure or Not to Measure

Interviews were conducted with 101 senior pastoral leaders from a variety of denominations in order to identify the ways in which pastors and those in authority positions over senior pastoral leaders measure their own effectiveness. The findings of these interviews revealed 23 measures of effectiveness in five categories, including leader outcomes, congregational outcomes, and objective outcomes. Based on the effectiveness taxonomy described in the current study, a process is suggested for a preliminary discussion among church leadership teams, congregational boards, and denominations to identify their primary mission, constituencies served, and related effectiveness priorities.     

Development and initial reliability and validity of a new measure of distorted maternal representations: The Mother–Infant Relationship Scale

Distorted maternal representations (DMRs)—mother's ideas, understanding, and feelings about the infant—shape early interaction and the emerging relationship. Distorted interactions reportedly affect infant attachment and socioemotional development and may be associated with maternal early adversity and trauma. Limited measures are available that could be used as screening tools of DMRs. The aims of this study were to (a) describe the development of the Mother–Infant Relationship Scale (MIRS) and (b) to evaluate its psychometric properties. The development and validation of the MIRS closely followed standard guidelines for the development of psychometric tests. Psychometric properties were examined across two samples: 78 adult psychiatric patients with features of borderline personality and 86 individuals from a nonclinical sample (N = 164). The scale demonstrated excellent internal consistency (Cronbach's α = .91) for the clinical sample and adequate internal consistency (.78) for the nonclinical sample, excellent test-retest reliability (intraclass correlation coefficient = .81), and good concurrent validity with an observational (Pearson's correlation coefficients = −.35 to −.54) and a representational measure (.53). Factor analysis revealed three components: DMRs specific to (a) maternal hostility/rejection of the infant, (b) issues about parenting/attachment, and (c) anxiety/helplessness about infant care. Findings suggest that the MIRS is a reliable and valid screening tool of DMRs. Potential uses in clinical and research settings are discussed.
