RESUMO
The purpose of this research was to investigate the psychometric characteristics of Pain Self-Management Checklist [PSMC] in the population with chronic pain. First, the checklist was administered to 186 patients with chronic pain, selected through random sampling in Tehran [n=86] and Ardebil [n=100]. Then, test-retest reliability coefficient was evaluated with another 30 patients with chronic pain. In addition to the PSMC, some other checklists including Physical Disability Questionnaire [PDQ], Depression, Anxiety, Stress Scale [DASS-21], Multidimensional Pain Inventory [MPI], and chronic pain case-finding questionnaire were used for data collection. To validate the PSMC, its correlation with other instruments was investigated, and the reliability was calculated using Chronbach's alpha and test-retest. The results indicated that this checklist has high correlation with most important pain co-morbidity constructs [depression, anxiety, stress and physical disability]. Therefore, it has appropriate construct validity. Moreover, the reliability of this checklist using Chronbach's alpha and test-retest was appropriate. This study provides evidence for the advantage of using this checklist for Iranian patients
