Description: A rapidly increasing population of persons are undergoing coronary angioplasty. This population has been understudied regarding risk factor modification, health maintenance, and role resumption. The purpose of this study was to explore the efficacy expectations for, and behavioral performance of, selected cardiac recovery behaviors (walking, diet modification, health maintenance, resuming roles, and work) in patients who experienced angioplasty. Additionally, the purpose was to describe the changes in patients' mood status over time, and the relationship of patients' mood status to efficacy expectations and behavioral performance.

Bandura's (1986) theory of self-efficacy provided the framework for this study. Major tenets of this theory include that efficacy expectations to engage in behavior impact initiation and persistence in behavior, and that efficacy expectations and behavioral performance are impacted by mood status. Data were collected from 90 subjects at three hospitals within 72 hours after angioplasty and after subjects were discharged at approximately 2 weeks after angioplasty.

Analyses included exploration of changes in efficacy expectations and mood status over time; determination of relationships between efficacy expectations and behavioral performance of the cardiac recovery behaviors; and determination of relationships between mood status, efficacy expectations, and behavioral performance.

Strength of efficacy expectations generally increased, and mood disturbance decreased, over time. Efficacy expectations were predictively and concurrently related to participation of each of the behaviors except work. Mood disturbance was predictively and concurrently inversely related to efficacy expectations to engage in the behaviors of walking, resuming roles, and work. Mood disturbance was concurrently inversely related to actual participation in the behaviors of walking, health maintenance, and resuming roles; mood disturbance was predictively inversely related only to actual participation in role resumption.

Ultimately, data collected during this recovery phase may be used to design interventions to enhance participation in cardiac recovery behaviors in persons experiencing coronary angioplasty. Suggestions for further research include examining sources of efficacy information and other factors thought to impact efficacy expectations and behavioral performance, extending data collection beyond the acute recovery period to gain knowledge of the predictive capabilities of acute recovery measures to long term outcomes, and designing clinical trials to test efficacy enhancing interventions.
