Homeostatic interactions: a longitudinal study of biological, psychosocial and family variables in children with cystic fibrosis

A two-Year longitudinal study of thirty-five children used data gathered from pulmonary function tests, clinical measurements and standardized tests of depression, self-esteem and family environment to illustrate homeostatic interactions among biological and psychosocial adaptation to cystic fibrosis. Despite physical deterioration over the course of the study, children with cystic fibrosis reported lower depression and higher self-esteem than population norms, and improvements in psychological functioning. Decline in biological indicators of health was associated with increases on an index based on Family Environmental Scales (FES), subscales of cohesion, expressiveness and organization, and maintenance of high self-esteem and low depression. Presence of additional major life stressors was associated with deterioration in pulmonary function, higher levels of depression and poorer scores on the FES. These findings suggest that homeostatic interactions between children's health status and family functioning may moderate the physical and psychological sequelae of cystic fibrosis.     

PROCESSING SPEED, WORKING MEMORY, AND FLUID INTELLIGENCE:

Abstract— Processing speed, working memory capacity, and fluid intelligence were assessed in a large sample ( N = 214) of children, adolescents, and young adults (ages 7 to 19 years) Results of path analyses revealed that almost half of the age-related increase in fluid intelligence was mediated by developmental changes in processing speed and marking memory and nearly three fourths of the improvement in working memory was mediated by developmental changes in processing speed Moreover, even when age-related differences in speed, working memory and fluid intelligence were statistically controlled, individual differences in speed had a direct effect on working memory capacity which, in turn was a direct determinant of individual differences in fluid intelligence     

Coping and sensitivity to aversive events

To test further the sensitivity to aversive events hypothesis, males and females varying in level of depressed mood listened to positive, negative, and neutral social scenes while psychophysiological measurements were obtained. In addition, the relations among response styles, coping strategies, and psychological adjustment were examined. Results indicated that only dysphoric females responded in ways consistent with the sensitivity hypothesis, exhibiting greater electrodermal responses to negative social scenes compared to nondysphoric females. No differences in psychophysiological sensitivity were found between dysphoric and nondysphoric males. Dysphoric students engaged in more ruminative type responses in reaction to their depressed mood and reported using more avoidant coping strategies in response to stress. In particular, females utilized more ruminative strategies in response to a depressed mood and more emotion-focused coping strategies in response to stressful events in general. The implications for these results are discussed within a diathesis-stress framework.     

Factors Influencing Managerial Disclosure of AIDS Health Information to Coworkers

This research investigates the importance of legal concerns over lawsuits, fear of AIDS in the workplace, and gender as factors influencing a manager's decision to disclose AIDS health information to coworkers. Data was obtained from questionnaires administered to managers employed in service, manufacturing, and government organizations. Findings indicate that both fear of AIDS in the workplace and concern over lawsuits exhibited a significant relationship with the likelihood of sharing AIDS health information and gender was found to moderate the relationship between likelihood of sharing AIDS health information, and fear of AIDS in the workplace. Male managers exhibited a higher level of fear of AIDS than female managers and did female managers, were found to be somewhat less likely than male managers to share AIDS health information with coworkers. Study findings, suggestions for future research, and implications are discussed.     

Effects of consent form information on self-disclosure

When researchers encounter preexisting psychological distress in participants, ethical codes provide little guidance on how to balance issues of beneficence and autonomy. Although researchers may inform participants what will occur given responses indicating distress, this information may lead to biased self-reports. This important issue was addressed in this study by manipulating consent form information regarding the type of psychopathology to be assessed and various levels of possible follow-up. In comparing responses on self-report measures of anxiety, depression, and general psychological distress, men who believed depression was the focus of the study reported fewer symptoms of depression and less trait anxiety as intrusiveness of experimenter follow-up increased. These results are discussed within the framework of socialization theory. Given that half of the sample did not correctly answer questions regarding information contained in the consent form, guidelines to improve consent form comprehension are offered.
