Social Support in Cardiac Rehabilitation Exercise Maintenance: Associations with Self‐Efficacy and Health‐Related Quality of Life1

This study examined whether cardiac rehabilitation (CR) maintenance exercise participants who were high and moderate in social support (SS) differed in their types of self‐efficacy and health‐related quality of life, and whether SS was related to self‐efficacy. Measures of SS, self‐efficacy (i.e., walking, scheduling, in‐class efficacy), and health‐related quality of life (HRQL) were administered to 64 CR maintenance exercise participants. A one‐way, between‐groups MANOVA was significant (p < .01), indicating that CR participants higher in SS reported significantly greater self‐efficacy and physical HRQL than did their moderate counterparts. In addition, social support predicted significant variance in task self‐efficacy. The findings suggest that differential perceptions of SS are related to differences in walking, in‐class and scheduling self‐efficacy, and the physical component of HRQL among CR exercise maintainers.     

Cannabiskonsum und -missbrauch bei Jugendlichen und jungen Erwachsenen

After a long time of growth current studies on representative samples of adolescents indicate that the number of adolescent cannabis users in Germany is possibly decreasing. However, it may be presumptuous to expect a similar trend concerning the number of clients with cannabis-related disorders. Even if there is in fact a downward trend which is not yet proven, the rapidly growing number of clients presenting with these disorders in recent years cannot be explained by a similar growth in the number of regular cannabis users. Treatment centres should therefore expect a further inreasing number of especially male adolescents and young adults seeking help for problems related to cannabis use. The development, evaluation and implementation of specific treatment options concerning cannabis use disorders will be increasingly needed in the future. Cognitive-behavioral and motivational interventions have been shown to be evidence-based treatments. The paper describes some promising or already successful treatment approaches and related research projects in Germany.     

Between- versus within-family factor analyses of cognitive abilities

Confirmatory factor analyses of the 15 cognitive abilities tests from the Hawaii Family Study of Cognition were conducted on between-family (BF) means and within-family (WF) differences for 370 AEA (Americans of European ancestry) and 116 AJA (Americans of Japanese ancestry) sibling pairs. Difference chi-square significance tests, goodness-of-fit indices, and congruence coefficients for the estimated loadings on four specific cognitive abilities factors and on the second-order general intelligence factor nearly all indicated that the between-family factor structures were not significantly different from the within-family structures for both AEA and AJA siblings (the AEA and AJA structures were also not significantly different). The similarity of the BF and WF structures suggests that the genetic and environmental influences underlying cognitive abilities are “intrinsic” in nature, that is, not just due to between-family differences in culture, status, values, and fortuitous cross-assortative mating.     

Gender and gender-role identity influences upon self- and other-reports of communicative competence

This study examines the influence of gender-role identity on interpersonal perceptions of communicative competence in a natural setting over an extended period of time. After working in small task-oriented groups for 15 weeks, 146 students (74 females, 72 males) completed a questionnaire containing measures of gender-role identity (Bem Sex Role Inventory) and communicative competence [J. M. Wieman, Explication and test of a model of communicative competence. Human Communication Research, 1977, 3, 195–213]. A three-way ANOVA (masculinity, femininity, gender) was used for analysis. Predictions based on prior models were only partially supported. Findings suggest that gender-role identity functions in more complex ways than prior models suggest. For all dimensions of communicative competence, gender-role identity resulted in different patterns for males and females. Furthermore, comparisons of self- vs other-perceptions indicate the possibility that one model may hold for self-perceptions and another for other-perceptions.The authors gratefully acknowledge the helpful comments contributed by Kenneth R.

The lived experience of disability

In this paper I reflect upon my personal experience of chronic progressive multiple sclerosis in order to provide a phenomenological account of the human experience of disability. In particular, I argue that the phenomenological notion of lived body provides important insights into the profound disruptions of space and time that are an integral element of changed physical capacities such as loss of mobility. In addition, phenomenology discloses the emotional dimension of physical disorder. The lived body disruption engendered by loss of mobility includes a change in the character of surrounding space, an alteration in one's taken-for-granted awareness of (and interaction with) objects, the disruption of corporeal identity, a disturbance in one's relations with others, and a change in the character of temporal experience. The loss of upright posture is of particular significance since it not only concretely diminishes autonomy but affects the way one is treated by others. Such a change in posture is, therefore, particularly disruptive in the social world of everyday life. An understanding of the lived body disruption engendered by disability has important applications for the clinical context in devising effective therapies, as well as for the social arena in determining how best to resolve the various challenges posed by chronic disabling disorders.I should like to thank Frances Chaput Waksler for her helpful comments on my work.     

Social approval and helping

An experiment was conducted to examine the role played by social approval as an incentive for helping behavior. After filling out the Marlowe-Crowne Social Desirability Scale, 95 female undergraduates were asked to make donations to a research fund under either public or private conditions. The following predictions, derived from social learning theory, were supported: (a) more money is donated under public conditions than under private conditions (p < .01), (b) more money is donated by individuals high in need for approval than those low in need for approval (p < .05), and (c) the effect of need for approval on donating is greater under public conditions than under private conditions (p < .05).     

The dimensionality of movement trajectories and the degrees of freedom problem: A tutorial

A framework for investigating the degrees of freedom problem (how the large number of degrees of freedom (dfs) at micro-levels of analysis are compressed to the smaller number of dfs at the macro-level of behavior) is discussed. The discussion centers around the use of dynamical systems as models of coordinative structures. Dimensionality analysis, a technique for assessing the dfs of an observable behavior, is explained both intuitively and in detail. By measuring the dfs being produced by actors, we can constrain our dynamical models of how actors produce coordinated behavior.     

Teaching gender-related material: The effect of group sex composition on perceptions of a female instructor

This study investigated how group sex composition affects female and male students' perceptions of female instructors who teach in the area of counseling women. Three components of person perception were assessed: cognitive, affective, and behavioral. The cognitive domain included evaluations of the instructor and the subject matter presented; the affective domain included emotional responses to the instructor and the subject matter; and the behavioral domain included actions in response to the instructor, operationalized as the number of questions asked by students. Students with some interest in a career in the helping professions viewed one of two videotapes either with a group of same-sex peers or in a group in which they were the only male or female. One tape described a gender-neutral topic (psychology and the law) and the other described a female gender-related topic (sex bias in counseling women). The same female instructor made both presentations. Students then completed the measures. As predicted, the sex composition of the student group affected person perception, especially in the affective and behavior domains. Recommendations are made for future research.This study was supported by a small grant from the University Research Institute, University of Texas at Austin. Appreciation is expressed to Sherry Fowler, Bob Haverstick, and Kathy Thomas for help with data collection and to Carolyn Bates and Ken Wilgus for coding the open-ended responses. A paper based on this research was presented at the meetings of the American Psychological Association, August 1987.
