The Purpose of this study was to investigate of coping strategies(active and passive) between pain beliefs and depression, pain disability among chronic back pain patients. Data were analyzed by the SPSS-WIN 21.0 program. Indirect SPSS macro(Bootsrapping)was used to analyze the multiple-mediation model of this study. The result showed that the mean score for pain belief was $3.42{\pm}9.67$, and he passive coping strategies was $29.68{\pm}8.04$, active coping was $25.49{\pm}4.22$. The mean score of depression was $25.49{\pm}11.56$. The pain disability index was $46.94{\pm}12.65$. It found that there were significant correlations among the 5 variables. The multiple mediated effects of passive coping and active coping on pain beliefs and depression were (b=.453, 95% CI=.228, .703) and on pain beliefs and pain disability were (b = .285, 95% CI = .131, .519) in chronic low back pain patients.
