RELATIONS BETWEEN WORK GROUP CHARACTERISTICS AND EFFECTIVENESS: IMPLICATIONS FOR DESIGNING EFFECTIVE WORK GROUPS

Five common themes were derived from the literature on effective work groups, and then characteristics representing the themes were related to effectivness criteria. Themes included job design, interdependence, composition, context, and process. They contained 19 group characteristics which were assessed by employees and managers. Effectiveness criteria included productivity, employee satisfaction, and manager judgments. Data were collected from 391 employees, 70 managers, and archival records for 80 work groups in a financial organization. Results showed that all three effectiveness criteria were predicted by the characteristics, and nearly all characteristics predicted some of the effectiveness criteria. The job design and process themes were slightly more predictive than the interdependence, composition, and context themes. Implications for designing effective work groups were discussed, and a 54-item measure of the 19 characteristics was presented for future research.     

Relatives' Perceptions of Their Interactional Behavior with a Schizop/hrenic Family Member

Relatives' (N = 77 ) perceptions of their recent interactional behavior with a schizophrenic family member (N = 51 ), as measured by an adjective checklist, were compared with outside observer ratings of the relatives' Affective Style (AS) and the patients' Coping Style (CS) during a family interaction task. Results indicated that, overall, the relatives in the present sample perceived their own interactional behavior toward the patient, as well as the patients' behavior toward them, in a way that paralleled their affective behavior as assessed by outside raters. Moreover, the relatives' rated their relationship with the patient in a fashion that was more predictive of the observed interactional behavior of both the relatives and the patients than were the outside observers' ratings of the relatives' Expressed Emotion (EE) measured either at the patients' index hospitalization (using the Camberwell Family Interview, CFI-EE) or during the post-discharge period (assessed with a brief Five-Minute Speech Sample method, FMSS-EE).     

Effects of Public Speaking Trait Anxiety and Intensity of Speaking Task on Heart Rate During Performance

The extant research examining the relationship between public speaking trait anxiety and heart rate has produced mixed findings. Some studies observe only weak relationships, whereas others report significant relationships between these variables. H. J. Eysetick has maintained that the degree of relationship between traits and heart rate depends on the stress levels under which the respondents perform when heart rate data are collected. An inspection of the existing studies shows that, consistent with Eysenck's observation, the studies reporting relationships between public speaking trait anxiety and heart rate were conducted under relatively low-intensity conditions in comparison to those reporting no such relationships. In the present study, heart rates of both anxious and nonanxious speakers were measured under both high- and low-intensity conditions. Results indicated that (a) heart rates of anxious speakers were significantly higher than those of nonanxious speakers when both performed under low-intensity conditions, but (b) heart rates were not different for anxious and nonanxious speakers when performing in high-intensity environments. These results provide a reconciliation of the inconsistent research findings and partially support the extension of Eysenck's conceptualization to communication apprehension theory and research.
