effectiveness of intervention based on transtheoretical model on pain self-efficacy and adaptation to disease in patients with chronic pain

The present study aimed to determine the effectiveness of transtheoretical therapy on pain self-efficacy and adaptation to the disease in chronic pain sufferers. The research method was semi-experimental with a pre-test-post-test design including a control group. The statistical population for this research included all patients with chronic pain referred to medical clinics in Tehran in 1400. Twenty individuals were randomly selected using available sampling methods and were assigned to two groups – experimental and control (each consisting of 10 people). To collect information, Drogatis's (1990) Disease Adaptation Questionnaire (PAIS) and Nicholas's (1977) Pain Self-Efficacy Questionnaire (PSEQ) were utilized. The data obtained from this research were analyzed using multivariate covariance analysis. The findings indicated that, after controlling for the pre-test effect, a significant difference existed between the post-test results of the experimental group and the control group in terms of pain self-efficacy and adaptation to the disease (P<0.001). Therefore, it can be concluded that the intervention based on the transtheoretical model was effective in enhancing pain self-efficacy and adaptation to the disease in patients with chronic pain.
