Psychometric characteristics of Pain Self-Management Checklist (PSMC) in Patients with Chronic Pain

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.
