Developing a model for online support group use,empowering processes and psychosocial outcomes for individuals living with HIV/AIDS

This study examined the mechanism through which online support group (OSG) participation may promote patient empowerment among 340 individuals living with HIV/AIDS. Results from structural equation modelling revealed that greater use of OSGs was associated with more frequent occurrence of the empowering processes as measured by receiving useful information, receiving social support, finding positive meaning and helping others. Receiving useful information and finding positive meaning were related to higher levels of adaptive coping and lower levels of maladaptive coping, while receiving social support and helping others were related to higher levels of self-care self-efficacy, which in turn was related to higher levels of adaptive coping, and lower levels of maladaptive coping. Finally, higher levels of maladaptive coping were related to poorer quality of life, while higher levels of adaptive coping were related to better quality of life. Results suggest that OSG participation may offer some benefits for those living with HIV/AIDS.     

Group cognitive-behavioral therapy for anxiety in a clinic setting: does child involvement predict outcome?

The current study examined the relationship between child involvement and treatment outcome in a group cognitive–behavioral treatment (GCBT) program for children with anxiety, using an adapted version of the Child Involvement Rating Scale (CIRS). Thirty-four children with a primary diagnosis of an anxiety disorder, referred for outpatient treatment at a hospital, and their parents participated in a manualized 12-session GCBT program. The Multidimensional Anxiety Scale for Children (MASC), administered at pretreatment, posttreatment, and at 4-month follow-up, served as the outcome measure. The psychometric properties of the adapted CIRS were good. Early involvement (EI) was calculated as the average score from Sessions 1 to 6 and late involvement (LI), the average score from Sessions 7 to 12. EI predicted lower MASC scores at posttreatment, after controlling for pretreatment MASC scores and for LI, B = – 1.05, t(3) = – 2.34, p < .05. EI did not predict outcomes at follow-up. Results were replicated using the original CIRS measure. Exploratory analyses suggested that the relationship between LI and treatment outcomes was moderated by medication. Involvement in therapy prior to exposures might be an important predictor of posttreatment outcomes in GCBT in a community setting.     

Clause boundaries and recognition latencies for words in sentences

In 35 sessions of 10 trials apiece, each of eight Ss viewed and judged a display which produced simultaneous brightness contrast. All Ss were given an instructional set toward realistic perception. Members of one subgroup were informed as to the magnitude of their judgments; members of another were not. For every S, there occurred highly significant changes in magnitude of simultaneous brightness contrast over time. There were wide individual differences in the nature of the changes, not all of which were decremental. No significant differences were found as between informed and noninformed groups. The results are viewed as giving limited support to the notion of learning in the perception of simultaneous brightness contrast.     

Factors influencing sexual performance in male rhesus monkeys.

A 5-yr retrospective study of the sexual behavior of eight adult male rhesus monkeys showed that sexual vigor declined over the years but testosterone levels in peripheral vein plasma did not. Two prospective experiments were then carried out on these males during the sixth year. (a) The four poorest performers were injected daily for 28 days with testosterone propionate (1 mg/kg of body weight). There was no significant increase in level of performance, and behavior was not correlated with plasma levels of testosterone either before or 24 hr after the last hormone injection. (b) All eight males were exposed to novel nonspecific sensory stimulation during tests of sexual behavior. Eight different adult male rhesus strangers-present in the room but not in the test cage-were used as stimuli, one for each experimental test. Sexual behavior during experimental and control tests did not differ.
