The Loneliness Questionnaire–Short Version: An Evaluation of Reverse-Worded and Non-Reverse-Worded Items Via Item Response Theory

Two Rorschachs were inadvertently administered to the same client within a period of three months. Although the ensuing personality pictures were very similar, an important difference appeared. The first Rorschach report stopped with the client's present condition. The second report saw the protocol as an interim Rorschach, suggesting the possibility that positive changes could lie ahead, if the client were given the appropriate help. The point is made that unwittingly, examiners may do their clients harm by not thinking ahead, in a way which the Rorschach uniquely makes possible. The Rorschach record and graph are presented, along with the various evidences of potential change. In conclusion, a problem is raised concerning the obligation inherent in the examiner-client relationship.     

Changes in plasma corticosterone and cerebral biogenic amines and their catabolites during training and testing of mice in passive avoidance behavior

Concentrations of cerebral biogenic amines and their catabolites, and of plasma corticosterone were determined 10 min after training and testing of passive avoidance behavior in mice. Training and testing of mice that had acquired the task well resulted in statistically significant increases of plasma corticosterone, of the DOPAC:DA ratio [an index of dopamine (DA) metabolism] in prefrontal cortex, and of MHPG:NE ratios [an index of norepinephrine (NE) metabolism] in hypothalamus and brain stem. There were also decreases of NE in hypothalamus and brain stem, and an increase of 5-HIAA:5-HT [an index of serotonin (5-HT) metabolism] and of tryptophan in brain stem. Some of these changes also occurred in mice merely exposed to the apparatus but not trained. Plasma corticosterone concentrations were significantly higher in mice that performed the task well compared to those that did not, and there were significant correlations between this measure and the avoidance performance. Although there was only one statistically significant correlation between a cerebral metabolite and the avoidance performance (a decrease in hypothalamic NE), there were indications of relationships between cerebral biogenic amine metabolism and the performance. The patterns of neurochemical and endocrine changes closely resemble those previously observed in response to various stressors. Thus, the changes could reflect stress responses, which may or may not be related directly to the performance of the avoidance task.     

The importance of modeling method effects: resolving the (uni)dimensionality of the loneliness questionnaire

This study sought to resolve the dimensionality of the Loneliness Questionnaire (LQ; Asher, Hymel, & Renshaw, 1984) by applying recommended confirmatory factor analytic procedures that control for method effects (Brown, 2003). This study was needed given that inconsistent findings have been reported recently regarding the structure of this instrument (Bagner, Storch, & Roberti, 2004) and all models to date have not accounted for method effects due to the non-reversed-worded and reversed-worded items of this instrument. Using a large sample of youth in Grades 2 through 12 (N = 11,725), we compared the previously reported 1- and 2-factor models with a newly posited 1-factor model that incorporated correlated error terms to account for method effects. We found that the 1-factor model that included correlated error terms fit the data best, and that this factor structure evidenced measurement invariance across boys and girls in childhood, but not in adolescence. The meaning of the LQ indicators was also consistent for boys across development, but evidenced differences for girls in childhood versus adolescence. More generally, it was demonstrated that modeling method effects is vital to accurately understanding the dimensionality of loneliness when reversed-worded and non-reversed-worded items are used as indicators. The measurement and clinical implications of these findings are discussed.     

Who Will Volunteer? Religiosity, Everyday Racism, and Social Participation Among African American Men

This study explores the relative importance of everyday racism, empathic concern, communalism, and religiosity as predictors of pro-social involvement (i.e., volunteerism and membership in political/social justice organizations) among a sample of African American men (N = 151). Church involvement emerged as a positive predictor of the likelihood that these men were involved in volunteer work as well as the number of hours that men dedicated to volunteer work. Communalism positively predicted the amount of time (in hours per year) that men were involved in volunteer work. Subjective religiosity and the stress of everyday racism were associated with a greater likelihood of being a member of a political–social justice organization. Implications of these findings are discussed.
