Allen and Meyer (1990) proposed a possible latent factor, role certainty, impacting the effects of socialization tactics on organizational commitment and role orientation. Their data was reanalyzed with structural equation modeling to test this proposal and to examine the overlooked factor of interaction with job incumbents. The results indicated the presence of two latent factors, role certainty, and incumbent interaction. More importantly, the most pronounced impact was from incumbent interaction. Interaction with incumbents had a strong early impact on organizational commitment of newcomers, but this effect diminished significantly over time. The implications of this are discussed.

Numerous studies have examined the relations between body concerns and exercise. This meta-analysis is based on 35 studies with exercise programs influencing body concerns. There was an overall effect of .45, suggesting that exercise positively affects body concerns. Moderator variables, such as sex, type of exercise, and length of intervention were examined and discussed. Generally, there were no sex differences in effects of exercise on body concerns, but anaerobic exercise such as weight training generated a stronger effect (d= .64) than aerobic-type exercises such as jogging (d= .40).

This study uses structural equation modeling and a panel design to explain participation in health protective behavior (HPB) among college students. The direct, indirect, and total effects of gender, social influences (parental and peer behavior), social attachments (activity involvement, social support, and romantic involvement), social triggers (personal health, acute illnesses, and personal or family health crisis), health value, and effort to improve health behavior on HPB are examined. A path model with a high goodness of fit and an R2 of .418 shows that gender; health value, and effort to change health behaviors are the most powerful predictors of HPB participation, while parents and peers influence HPB indirectly through influence on health value and effort to change. Neither the social attachment nor social trigger items influenced HPB in this sample. Implications of these findings are discussed.
