This study examines whether a community-based physical activity intervention influenced movement in stages of change in physical activity in an adult population, whether any such effect was mediated by psychosocial influences, and whether any such mediations were moderated by sociodemographic or anthropometric factors. The 3-year-long…

This study examined the trajectories of delinquency among Puerto Rican children and adolescents in two cultural contexts. Relying on data from the Boricua Youth Study, a longitudinal study of children and youth from Bronx, New York, and San Juan, Puerto Rico, a group-based trajectory procedure estimated the number of delinquency trajectories,…

This study examined the relative impact of intrinsic and extrinsic motivation and personality variables on procrastination behavior of college students. A total of 96 undergraduates completed the Procrastination Assessment Scale-Students, the Multidimensional-Multiattributional Causality Scale, the Brief Fear of Negative Evaluation Scale, the Work…

A study investigated the relationship between locus of control and intrinsically motivated reading for children. The entire sixth grade, totalling 53 students, of a parochial school in San Francisco was administered the Children's Nowicki-Strickland Internal-External Control Scale. A free-choice paperback reading rack provided the measure for…

People's beliefs about the origins of their health, sometimes referred to as health locus of control, have been shown to influence a variety of important behaviors. The purpose of this study was to explore the structure of the health locus of control beliefs of children, using the Multidimensional Health Locus of Control Scales. Two samples of…

Two theoretical areas that lend themselves to study as they relate to supervisor-worker relations are locus of control and attribution theory. This study examined two general problems: (1) how a supervisor behaves toward an employee in relation to how that employee performs in the work place; and (2) how a supervisor's locus of control influences…

A total of 24 children, meeting several criteria for being diagnosed as having an attention deficit disorder with hyperactivity, were selected for study.

The effect of mastery learning procedures on achievement and students' attributions for learning outcomes was studied with undergraduates enrolled in a general education course at a large state university. Most of the students were juniors and all had met selective admission requirements. It was hypothesized that mastery learning would result in…

In separate research studies, students who were given a choice of learning materials or who had control over aversive noise, demonstrated higher motivation and better task performance. To investigate the additive effects of choice and control on perception of control, 80 male and female college students participated in a 2 (choice vs. no-choice) X…

This paper criticizes the Future Events Test and conclusions drawn from it on the grounds that the test contains sex-biased items and that locus of control scales have shown no reliable sex differences. (GO)

This study indicates that the vertical ordering of self-social others is a potent measure of individual differences in social orientations. (Author)

Investigates whether direct and nondirect therapist techniques within a 23-hour marathon format would differentially induce client shifts in locus of control.
