Abstract

Objectives: The Multidimensional Pain Readiness to Change Questionnaire 2 (MPRCQ2) is a reliable and valid measure that assesses readiness to adopt a variety of discrete pain self-management responses. We sought to translate and evaluate psychometric properties of the Japanese version of the MPRCQ2 (MPRCQ2-J) in individuals with chronic pain.

Methods: One hundred seventy-three individuals with chronic pain were asked to complete the MPRCQ2-J, as well as measures assessing pain intensity, pain interference, self-efficacy, and general readiness to adopt a self-management approach for pain. Forty-eight of these participants provided additional MPRCQ2-J data to assess test-retest reliability.

Results: The findings supported a 2-factor structure of the MPRCQ2-J when error covariances between the some of the nine primary scales were allowed. Adequate internal consistencies of the MPRCQ2-J scales (Cronbach's α ranged 0.71 to 0.86), except for the total score (α = 0.68), were observed. However, adequate test-retest reliabilities (intraclass correlation coefficients ≥ 0.60) were found for only 59% of the MPRCQ2-J scales. The MPRCQ2-J evidenced its construct validity via confirmation of the predicted patterns of associations with validity criterion measures and the anticipated effects of participation in an exercise treatment.

Discussion: The findings support the internal consistency (except for the total score) and construct validity for MPRCQ2-J scales. However, potential limitations with respect to test-retest reliability of some of the scales were also suggested. The MPRCQ2-J can be used to examine the role that specific readiness domains of pain self-management responses may play in an adjustment process in Japanese individuals with chronic pain.
