Psychometric properties of an Arabic translation of the chronic pain acceptance questionnaire (CPAQ) in a sample of patients with chronic pain

PurposeChronic pain (CP) acceptance is a major factor in determining the well-being of patients with chronic pain. The chronic pain acceptance questionnaire (CPAQ) was translated and validated into Arabic (CPAQ-Ar).Methods244 patients with CP completed the CPAQ-Ar, the Beck Depression Inventory-II (BDI-II), the short form health survey (SF-36), the Pain Catastrophizing Scale (PCS), the Pittsburgh Sleep Quality Index (PSQI), the Modified Fatigue Impact Scale (MFIS), and the Depression Anxiety Stress Scale 21 (DASS-21). 110 patients completed the CPAQ-Ar twice separated by two weeks to investigate test-retest reliability.ResultsCronbach's alpha was 0.902 while the intraclass correlation coefficient (ICC) was 0.917. The standard error measurement (SEM) was seven points while the minimal detectable change with 95% confidence interval (MDC95) was seventeen points. The CPAQ-Ar showed moderate to high correlations with the PCS, the BDI-II, the SF-36, the MFIS, the PSQI, and the DASS-21 indicating a good concurrent validity. Exploratory factor analysis confirmed that the CPAQ-Ar consists of two subscales. Better pain acceptance associated with male gender, older people, employed participants, low pain intensity, and single pain site.ConclusionsThe CPAQ-Ar is a valid and reliable tool for the measurement of pain acceptance in Arabic speaking patients with CP.

Automated summary

The Chronic Pain Acceptance Questionnaire (CPAQ) was translated and validated into Arabic (CPAQ-Ar), and the results showed good reliability and validity in Arabic-speaking patients with chronic pain. The CPAQ-Ar consists of two subscales, and better pain acceptance is associated with male gender, older age, employment, low pain intensity, and single pain site.
