Understanding Predictors of Engagement Within the Military

The current study explored organizational antecedents of employee engagement in a military organization. A survey was administered to junior military personnel assessing leadership effectiveness, role clarity, organizational culture, and peer group interactions as predictors of engagement. Leadership's influence on engagement was expected to be partially mediated by role clarity and organizational culture. Engagement was predicted to fully mediate the relationship between the aforementioned variables and turnover intentions. Results indicated that leadership's influence on engagement was fully mediated by role clarity and organizational culture. In addition, engagement fully mediated the relationship between all variables and turnover intentions.     

Threat-related processing supports prospective memory retrieval for people with obsessive tendencies

Obsessive-compulsive disorder can result in a variety of deficits to cognitive performance, including negative consequences for attention and memory performance. The question addressed in the current study concerned whether this disorder influenced performance in an event-based prospective memory task. The results from a subclinical population indicated that, relative to non-anxious controls and mildly depressed controls, people with obsessive-compulsive tendencies (washing compulsions) incur decrements in remembering to respond to cues related to a neutral intention (respond to animals). This deficit was ameliorated by giving the subclinical group an intention about a threat-related category (respond to bodily fluids) and cueing them with concepts that they had previously rated as particularly disturbing to them. Thus, their normal attentional bias for extended processing of threat-related information overcame their natural deficit in event-based prospective memory.     

Family,public and private religiousness and psychological well-being over time in at-risk adolescents

Positive effects of different dimensions of religiousness (including private, public and familial) on well-being as well as the stress buffering effects of religiousness have been documented. However, relatively little research has explored how these different facets of religiousness are related to psychological well-being in at-risk adolescents. This study examined family, public and private religiousness and their protective influence on psychological adjustment in adolescents at risk for poor psychological and behavioural outcomes. Participants include 186 urban teens divided between African Americans and European Americans. Structured interviews assessed religiousness, stress, as well as change in emotional distress and substance abuse problems over a one-year period. Greater private religiousness protects adolescents exposed to higher levels of stress from emotional and behavioural problems. In contrast, higher levels of family religiousness exacerbate emotional problems over time in adolescents exposed to greater stress. Findings demonstrate the complex influence of religiousness on psychological well-being in adolescence.     

Predictors of spiritual struggles: an exploratory study

The purpose of the current study was to identify factors that predict spiritual struggles. It was hypothesised that factors from religious (e.g., God image, attachment to God, church attitudes, religious history), personal (e.g., neuroticism, pessimism, trait anger), social (e.g., social support, loneliness), and situational (e.g., negative appraisals) domains may predispose people to spiritual struggles during times of distress. Participants (309 undergraduate students) filled out questionnaires measuring relevant constructs and a two-step hierarchical multiple regression equation was generated separately for each of the four domains. Upon identifying significant predictors from each of the four domains, a final hierarchical regression equation revealed that: (1) more negative appraisals of a stressful situation, (2) an insecure ambivalent attachment to God, and (3) neuroticism significantly predicted unique variance in spiritual struggles beyond the effects of relevant religious variables, thus generally supporting the hypothesis that spiritual struggles are complex phenomena that stem from multiple factors.     

Therapeutic Assessment With Children: A Pilot Study of Treatment Acceptability and Outcome

Therapeutic Assessment (TA) with children is a hybrid of psychological assessment and short-term intervention. It uses the ongoing process and results of psychological assessment to enhance parents' understanding of their child and to facilitate change. Clinical reports and single case studies suggest that TA with children is an acceptable and effective brief intervention. However, no aggregate data have been published to support this claim. This pilot study investigated the acceptability and preoutcome–postoutcome of TA with 14 clinically referred children with emotional and behavior problems and their parents. Results indicated high treatment acceptability as well as significantly decreased child symptomatology and enhanced family functioning as reported by children and mothers. In addition, mothers demonstrated a significant increase in positive emotion and a significant decrease in negative emotion pertaining to their children's challenges and future. The findings, although limited due to the design and small sample size, support assertions from published single case studies that TA is possibly an efficacious child and family intervention for children with emotional and behavioral problems and should be studied in a larger, comparison design.     

Distinction in Psychology and the Alma Mater

With use of several indices of distinction, the biographies of selected samples of psychologists were examined to determine which educational institutions produced a disproportionate number of those alumni who recently have occupied positions of eminence in the field. Unlike other investigations that have attempted to rank departments of psychology on the basis of the quality of their current faculties, the present study focused on the doctoral and baccalaureate origins of prominent psychologists rather than on the institutions where they now reside. In general, it was found that among well established psychology programs, the same few universities tend to have produced more than their share of doctoral students who made significant career contributions to the field, although the precise rank ordering varied according to the particular index of distinction employed. With notable exceptions, the higher ranking graduate programs were also the undergraduate alma maters of a significant proportion of this same generation of scholars.     

Constructing Confidence Intervals for Effect Size Measures of an Indirect Effect

Confidence intervals for an effect size can provide the information about the magnitude of an effect and its precision as well as the binary decision about the existence of an effect. In this study, the performances of five different methods for constructing confidence intervals for ratio effect size measures of an indirect effect were compared in terms of power, coverage rates, Type I error rates, and widths of confidence intervals. The five methods include the percentile bootstrap method, the bias-corrected and accelerated (BCa) bootstrap method, the delta method, the Fieller method, and the Monte Carlo method. The results were discussed with respect to the adequacy of the distributional assumptions and the nature of ratio quantity. The confidence intervals from the five methods showed similar results for samples of more than 500, whereas, for samples of less than 500, the confidence intervals were sufficiently narrow to convey the information about the population effect sizes only when the effect sizes of regression coefficients defining the indirect effect are large.

The development of the concept of time in third, fifth, and seventh graders of two Israeli social groups—advantaged Westerners (n = 144) and disadvantaged Easterners (n = 120)—was compared. Contrary to expectations, no difference in performance was found between the social groups throughout the entire age range. In both groups performance, while far from reaching perfection, increased with age. In addition, disparity between our findings and those of Siegler and Richards cast doubts on the generalizability of the rules they extracted through the rule-assessment method.     

Addiction: An Emergent Consequence of Elementary Choice Principles

ABSTRACT

Clinicians, researchers and the informed public have come to view addiction as a brain disease. However, in nature even extreme events often reflect normal processes, for instance the principles of plate tectonics explain earthquakes as well as the gradual changes in the face of the earth. In the same way, excessive drug use is predicted by general principles of choice. One of the implications of this result is that drugs do not turn addicts into compulsive drug users; they retain the capacity to say ‘no’. In support of the logical implications of the choice theory approach to addiction, research reveals that most addicts quit using drugs by about age 30, that most quit without professional help, that the correlates of quitting are the correlates of decision making, and, according to the most recent epidemiological evidence, the probability of quitting remains constant over time and independent of the onset of dependence. This last result implies that, after an initial period of heavy drug use, remission is independent of any further exposure to drugs. In short, there is much empirical support for the claim that addiction emerges as a function of the rules of everyday choice.     

Association of social-environmental factors with cognitive function in children with sickle cell disease

The aim of this study was to examine the relationship between cognitive function in pediatric sickle cell disease (SCD) patients and mothers’ reports of social-environmental stress, depressive symptoms, and parenting. A total of 65 children with SCD completed comprehensive neuropsychological testing to assess several domains of cognitive functioning, including general intellectual ability, academic achievement, and executive function. Mothers reported on demographics, social-environmental stress, depressive symptoms, and parenting. As predicted, children with SCD significantly underperformed relative to normative data on measures of cognitive function. Associations between maternal social-environmental stress, maternal depressive symptoms, and parenting were mixed. The results show partial support for the hypothesis that greater stress and depressive symptoms and less positive parenting are associated with poorer cognitive function in children with SCD. Linear regression analyses showed that maternal financial stress was the strongest predictor across all domains of cognitive function. The findings replicate and extend past research, reaffirming that children with SCD are at risk for cognitive impairment across multiple domains. Additionally, social-environmental stress, particularly financial strain, is linked to mothers’ depressive symptoms and parenting behaviors as well as children’s cognitive function. Future studies using direct observations of parenting behaviors are needed. These findings, along with recent research on parenting interventions, may inform the development of concrete, teachable parenting and coping skills to improve cognitive functioning in children with SCD.
