Abstract:
The purpose of this study was to examine the relationship between perceived stress and wellness in early adolescents and to test primary appraisal as a mediator of this relationship using the Neuman Systems Model as the primary framework. The sample consisted of 144 adolescents, ages 12-14, who responded to instruments measuring perceived stress, primary appraisal, and wellness in classroom settings. Correlational analysis supported the three hypothesized relationships. A series of regression analyses indicated that primary appraisal was a weak mediator of the relationship between perceived stress and wellness. Implications for nursing and recommendations for future studies were addressed.
