The causes of organizational citizenship behavior: a motivational analysis.

This study addressed the role of motives in organizational citizenship behavior (OCB). Three motives were identified through factor analyses: prosocial values, organizational concern, and impression management. Scales that measured these motives and other variables known to covary with OCB were administered to 141 municipal employees and were correlated with self-, peer, and supervisor ratings of 5 aspects of OCB. Relative to the other motives, prosocial values motives were most strongly associated with OCB directed at individuals, and organizational concern motives were most strongly associated with OCB directed toward the organization. Each of the motives accounted for unique amounts of variance in OCB. The results suggest that motives may play an important role in OCB.

Individual differences in intraperson variability in mood.

The experience sampling method and palm-top computers were used to obtain 75-100 randomly timed in situ assessments of 11 mood-related items from 54 Ss over 12-14 days. The variability in the distribution of an S's responses to each item was used as an estimate of intrasubject mood variability. Mood variability was stable across time (average r > .58) and across situations (average r = .51). The intercorrelations among the individual item variabilities were also substantial (average r = .41); when the items were combined into a mood variability scale, the coefficient alpha was .84. The stability and internal consistency of mood variability could not be reasonably attributed to similarity in item valences, differences among the Ss in the situations they encountered, response biases, or response errors. It was concluded that mood variability is a stable personal characteristic, but additional analyses suggested that it may be independent from other kinds of intraperson variability.

Size overestimation among anorexics: much ado about very little?

Research on size overestimation among anorexics has failed to control for the effects of actual body size on estimated size. We obtained estimates of the size of 3 body sites from 3 groups: 13 anorexic women; 13 non-eating disordered women matched with the anorexics on actual body size; and 13 non-eating disordered women of average size. The anorexic and size-matched normal subjects did not differ in the extent to which they overestimated their body size, but both displayed significantly greater overestimation than did the subjects of average size. Both groups also estimated the actual size of their body sites to be larger than did average-size normal subjects. These findings illustrate the need for appropriate control procedures when considering body image disturbances among persons with eating disorders, and they raise questions about the psychological significance of disturbances in the perceptual component of body image.
