Moderators of the relationship between exercise and mood changes: gender,exertion level,and workout duration

Although the role of exercise in improving mood is well established, less is known about moderators of this effect, particularly outside of the laboratory. The current study examined the effect of gender, type of exercise, level of exertion, and duration of workout on the exercise–mood relationship in a naturalistic setting. One hundred and thirty five participants (64 females) either engaged in weight training (n = 52) or cardiovascular (n = 83) exercise. Pre- and post-exercise assessments of mood were collected and changes in two types of mood, negative mood and exhaustion, were examined. Overall, participants reported improved mood after exercise in both domains. Workout duration and level of exertion significantly moderated the relationship of exercise to mood improvement (i.e., an increase in either corresponded to greater improved mood, ps<0.05). Overall, women showed more improved mood than men in the domain of exhaustion (p = 0.001).     

Reliability and Validity of the Dyadic Observed Communication Scale (DOCS)

We evaluated the reliability and validity of the Dyadic Observed Communication Scale (DOCS) coding scheme, which was developed to capture a range of communication components between parents and adolescents. Adolescents and their caregivers were recruited from mental health facilities for participation in a large, multi-site family-based HIV prevention intervention study. Seventy-one dyads were randomly selected from the larger study sample and coded using the DOCS at baseline. Preliminary validity and reliability of the DOCS was examined using various methods, such as comparing results to self-report measures and examining interrater reliability. Results suggest that the DOCS is a reliable and valid measure of observed communication among parent-adolescent dyads that captures both verbal and nonverbal communication behaviors that are typical intervention targets. The DOCS is a viable coding scheme for use by researchers and clinicians examining parent-adolescent communication. Coders can be trained to reliably capture individual and dyadic components of communication for parents and adolescents and this complex information can be obtained relatively quickly.     

Distinctions Between Worry and Perceived Risk in the Context of the Theory of Planned Behavior

Worry and risk perception were integrated into the theory of planned behavior (TPB) within health and non-health domains (flossing and academic coursework, respectively). Models were estimated and replicated in 2 undergraduate samples ( n s = 191 and 309), with effects of worry and risk on intentions expected to occur primarily through attitudes. Past behavior was modeled through effects on all TPB constructs and through interactions with worry and risk. Worry positively predicted intentions and attitudes (and norms in the non-health domain) for those at the lowest levels of prior behavior. Risk perceptions negatively predicted intentions and self-efficacy (and attitudes in the health context) also for those at low levels of prior behavior. Implications for further theory development are discussed.     

What Matters to Stakeholders? Measuring Values at a University Museum

ABSTRACT

Perceptions of museum performance may be linked to individual values. This study asked members of different groups that hold a stake in a university museum (e.g., Alaska Native, Art Community, Business Community, Donors/Museum Members, Military Leaders, Science Community, K–12 Teachers, University Leaders) what they valued about their museum's performance. Results indicate that key differences exist with respect to performance indicators among some groups; however, stakeholders as a whole highly value indicators related to the human face of the museum and the collections. Museums can use these results to develop and pursue appropriate goals for specific audiences and to develop performance reports that matter to stakeholders.     

Influence of social stigma on subjective well‐being of persons with albinism in Ghana

Previous studies have shown that social stigma adversely affects quality of life. However, little research has assessed the influence of social stigma on subjective well‐being (SWB) of persons with albinism (PWA) in Ghana, and the role that perceived social support plays in this relationship. This study investigated the SWB of PWA in Ghana. Participants (N = 105) completed a survey questionnaire on social stigma, social support, and SWB. Results from structural equation modelling showed a significant negative association between social stigma and SWB. Perceived social support partially mediated the negative effect that social stigma has on SWB, with significant other support emerging as a reliable predictor of SWB in this sample. Results suggest that the population with albinism in Ghana is experiencing high levels of social stigma, which is adversely affecting its SWB. Social stigma seems to be preventing PWA from being accorded the needed social support by family and friends. The results highlight the importance of designing stigma‐reduction educational interventions that target social stigma at family, community, and societal levels.     

Performance of Dyslexic Children on Cerebellar and Cognitive Tests

In a previous study (A. J. Fawcett, R. I. Nicolson, & P. Dean, 1996), the authors had found strong behavioral evidence for cerebellar deficit in a panel of children with dyslexia. In the present study, the generality of those results was assessed. A battery of clinical tests for cerebellar dysfunction was administered, together with selected cognitive tests, to a further 59 dyslexic and 67 control children. The dyslexic children showed highly significant impairments on the cerebellar tests, with deficits on postural stability and muscle tone comparable in magnitude with their reading and spelling deficits. Furthermore, over 95&percent; of the dyslexic children showed clear evidence of deficit on muscle tone or stability. The findings provide further evidence of the generality of cerebellar impairment in dyslexia. The implications of the cerebellar tests for screening in dyslexia are discussed.     

Effects of team and organizational commitment – A longitudinal study

Retention management, i.e., keeping qualified employees, is a top priority for contemporary organizations. Commitment, and especially team commitment, can be the key to mastering this challenge. There is a lack of longitudinal research concerning the development and the direction of the effects of team commitment over time. In a longitudinal field-study design with three points of measurement, a total of 360 employees in 52 semi-autonomous industrial teams were surveyed over a period of three years. On the one hand, organizational commitment showed stronger effects on organization-related criteria (job satisfaction and intention to leave). These effects were consistent over the three points of measurement. Team commitment, on the other hand, affected team-related criteria (team performance and altruism). Longitudinal analyses confirmed the effects of organizational commitment on job satisfaction and intention to leave, and of team commitment on team performance and altruism. Moreover, these effects increased over time. Theoretical and practical implications of these findings are discussed.     

The role of behavior analysis in the rehabilitation of persons with dementia

With the rapidly aging population, it is expected that increases in cases of dementia will double over the next 20 years. Currently, there is no cure for diseases such as Alzheimer's disease or frontotemporal dementia (FTD) that cause progressive dementia, and only a few pharmacological interventions that slow the progression of the decline exist. Given that there is no cure available, a rehabilitation approach that emphasizes maintaining existing abilities and removing excess disability (as opposed to emphasizing cure or recovery) for as long as possible is warranted. The current paper proposes that nonpharmacological rehabilitation efforts need to target 5 broad areas/targets: memory enhancement, altering social contingencies and communication styles, improving self-care skills, the arrangement of physical environments to maintain and improve functioning, and increasing physical fitness/physical activity. The purpose of this paper is to review specific behaviorally oriented interventions that target these 5 areas and show promise for inclusion in comprehensive rehabilitation efforts for individuals with dementia.
