A Theory Based Study Predicting Factors of Physical Activity Behavior among Chronic Low Back Pain Patients Referred to Pain Clinic in Yazd, Iran

Background: Low level Physical Activity (PA) among Chronic Low Back Pain for (CLBP) has been reported in many studies. The aim of this study was to predicting factors for physical activity behavior among CLBP patients referred to pain clinic in Yazd, Iran.Methods and Materials: This cross sectional study was conducted on 182 eligible patients with CLBP who referred to pain clinic in Yazd, Iran from October to December 2016. A socio-demographic questionnaire as well as a 14-item researcher-made questionnaire regarding physical activity predictors based on Theory of Reasoned Action (TRA) were used to collect data. Data were inserted into SPSS v.23 and AMOS v. 23 and analyzed using descriptive/analytical tests including linear regression analysis.Results: Totally 182 individuals with mean age of 42.18 ± 13.12 completed the study. The results showed behavioral beliefs and evaluation of behavioral outcome of PA were predictors of patients' attitudes towards PA (P < 0.001). Normative beliefs and motivation to comply were also predictors of subjective norm (P < 0.001). Subjective norm was predictor for intention to perform the PA behavior (P < 0.001) that in turn was predictor for PA behavior (P < 0.001). However, attitudes towards PA was not predictor for intention to do PA (P = 0.085).Conclusion: This study showed the individuals who had positive beliefs and evaluation regarding outcomes of PA were more likely to do this behavior.
