An Expectancy Theory Approach to Group Coordination: Expertise,Task Features,and Member Behavior

Working in a group requires coordination. The current paper examines coordination in terms of member‐level behavioral choices. Extending expectancy theory to a collaborative group setting, we interpret past findings on expertise and hypothesize that component features (specifically their difficulty and worth relative to each other) impact member behavior and hence coordination both directly and by moderating the role of expertise. Findings were largely as predicted, suggesting that an expectancy theory perspective may be a useful tool for the study and understanding of coordination. An exploratory examination of recordings of group interaction suggested that although most of our groups discussed coordination strategies, the strategies discussed did not generally map to the behavioral choices observed. Implications for coordination in general and transactive memory specifically are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Predicting participation in premarital prevention programs: the health belief model and social norms

The development of effective programs to prevent marital dysfunction has been a recent focus for marital researchers, but the effective dissemination of these programs to engaged couples has received relatively little attention. The purpose of this study is to determine which factors predict couples' participation in premarital counseling. Predictive factors were derived from the health prevention literature, with a particular focus on the health belief model (HBM). Couples' beliefs and attitudes about premarital counseling were assessed at least six months before their wedding, and participation was assessed after their wedding. Results indicate that the strongest predictors of couples' participation were couples' perceptions of barriers to counseling and whether they had counseling recommended to them. These variables predicted participation even after controlling for important demographic variables. Recommendations for recruiting engaged couples for premarital counseling are made based on the findings.     

Factor structure and use of the hospital anxiety and depression scale in the homeless and socially marginalized

The homeless have been identified as a group at risk of significant anxiety and depression and screening is therefore highly desirable to identify those needing psychological and psychiatric support. However, the psychometric properties of routine screening instruments have yet to be established in this group. This study sought to determine the psychometric properties of the widely used Hospital Anxiety and Depression Scale in this group. Using a cross-sectional design, 314 clients presenting at homelessness units (shelters) supported by The Salvation Army were administered the HADS. Confirmatory factor analysis revealed three-factor models offered the best fit to the data (best-fit model CFI = .98, RMSEA = .06, WRMR = .87). This investigation confirms contemporary research findings that the HADS comprises an underlying tri-dimensional factor structure. However, the internal consistency of the HADS anxiety (alpha = .81) and depression (alpha = .90) sub-scales was excellent. The findings of the current study suggest that the HADS is a suitable screening tool in this group.     

Dispositional and task-specific social-cognitive determinants of physical effort perseverance

The authors performed 3 studies to investigate the effects of social-cognitive variables on physical effort perseverance. Linear hierarchical regressions indicated that task-specific variables and perceived ability or competence accounted for the majority of perseverance variance in all 3 studies. The strongest single predictors in this cluster of variables were perceived competence, confidence, and readiness to invest effort. Physical self-health and ability accounted for a lesser portion of effort perseverance variance, with self-presentation confidence being the major single predictor in this cluster. The goal orientation cluster accounted for the least amount of effort perseverance variance. Together with task-specific confidence and the readiness to invest effort, as well as determination and commitment and competence, the findings support the contention that task-specific efficacious beliefs to a large extent determine persistence and endurance behaviors.     

The "don't ask, don't tell" policy and military performance

This paper is a response to Schumm's 2004 critique of Belkin's 2003 article, dealing with the "Don't Ask, Don't Tell" policy in the U.S. military. Schumm's critique specified four reasons for continuing to exclude homosexuals from military service: military effectiveness, sexual asymmetries, Christian soldiers' dilemma of "living a lie" and skewed opinions of policy makers and military elites. Each of these categories is analyzed and discussed.     

Postnatal development of lateralized motor preference in the African grey parrot (Psittacus erithacus)

The parrot appears to provide a potentially unique animal model of handedness in humans, but few (if any) observational studies of early postnatal development of postural/motor asymmetries have been published. We studied three African Grey hatchlings, raised without human physical contact, for the first 5 months of life. All three animals failed to show consistent postural and/or motor asymmetries until the end of the 4 postnatal week. These results appear to be comparable to data from prior studies with human infants. Delayed development of lateral motor and/or postural preferences may represent an evolutionarily adaptive strategy for altricial animals.     

Correctional suicide prevention in the year 2000 and beyond

Although the problem of suicide in jail and prison historically has been ignored, significant insight has been gained over the past several decades due primarily to increasing litigation. This article provides a brief overview of the progress in research, programming, and policy. The new millennium offers exciting opportunities for continued growth in correctional suicide prevention. The key areas of process research, risk assessment, and public and penological policy changes are reviewed and considered vital for the field's advancement.     

Psychosocial vulnerability, life stress, and suicide ideation in a jail population: a cross-validation study

The purpose of this present investigation was to cross-validate a stress-psychosocial vulnerability model of suicidal ideation and behavior in a jail population. Measures of social alienation, cognitive distortions, adaptive resources, situational (jail environment) stress, depression, hopelessness, and suicide ideation were administered to 146 male inmates at a county jail facility. It was predicted that each of the vulnerability factors, in addition to jail stress, would be significantly related to suicide ideation among inmates. Furthermore, it was hypothesized that psychosocial vulnerability among inmates would interact with jail stress to best explain suicide intent. The result of a multiple-regression analysis, stepwise forward-inclusion algorithm, indicated that 51% of the variation in suicide ideation could be accounted for by the linear combination of low reasons for living, irrational beliefs, jail stress, and loneliness. In addition, when the variables were entered into a hierarchical multiple-regression model, interactions between select psychosocial vulnerability factors and jail stress were found to best explain suicide intent. Results of the study are discussed in terms of the proposed model, and implications for future research and prevention efforts in jail suicide are noted.
