Development of content: influences on girls' junior high school volleyball success in practice and achievement.

The purpose of this study was to examine the success of practice by lower- and higher-skilled girls in Grades 7 and 8 in response to different tasks (extension, refinement, and application) throughout an 11-day instructional and practice period for volleyball. More highly skilled girls were more successful than those lower in skill for all skills (forearm pass, set, serve) and tasks. Girls had nearly equal success in practice for different tasks.

Relations between preventive health behavior and hardiness.

To estimate the relationship between hardiness and preventive health behaviors a hardiness scale and a health hazard appraisal were administered to 211 college students. Multiple regression analysis indicated that modest amounts of variance on the hardiness measures were explained by the components of the health-hazard appraisals. Indications are that the concepts of hardiness and preventive health behavior are related and need further clarification.
