Effects Of Moderate Intensity Exercise Program On Percived Self-Efficacy, Outcome Expectation On Exercise Behavior And CD4 Levels In Persons With Asymptomatic HIV

Abstract

          This pre-experimental study aimed to investigate the effects of moderate intensity exercise program on perceived self-efficacy, outcome expectation on exercise behavior, exercise behavior, and CD4 levels in persons with asymptomatic HIV. Self-Efficacy theory (1997) ¹ was used as a conceptual framework to develop the program. A purposive sample of 15 was recruited from out-patient department of Bamrasnaradura Infectious Disease Institute. The moderate intensity exercise program comprised 3 phase i.e., preparation, self exercise training, and evaluation. The research instruments composed of 1) demographic sheet 2) perceived self - efficacy questionnaire 3) perceived expected outcome of exercise questionnaire 4) exercise behavior questionnaire 5) collecting data sheet of CD4 level and 6) the moderate intensity exercise program .Content validity of the perceived self - efficacy questionnaire, perceived expected outcome of exercise questionnaire, exercise behavior questionnaire was approved by three experts. Internal consistency reliability of perceived self - efficacy questionnaire, perceived expected outcome of exercise questionnaire, exercise behavior questionnaire was 0.91, 0.88, and 0.88 respectively. Descriptive statistics, Wilcoxon Signed-Rank test and pair t-test were used in data analysis.

          The finding showed that the self-efficacy score, the perceived expected outcome of exercise score, exercise behavior score after participating in the exercise program were statistically significant higher at the level of p-value = 0.001, 0.001, 0.000 respectively. However CD4 level was not statistically difference (p-value = 0.079). The finding suggests that this exercise program is effective in improving exercise behavior. Therefore, this program could be used for promoting health among person with asymptomatic HIV.
