Cross-cultural adaptation of the Pain Medication Questionnaire for use in Brazil.

ABSTRACT: BACKGROUND:The Pain Medication Questionnaire (PMQ) assesses the risk of opioid abuse in people with non-oncological chronic pain. METHODS:This is a methodological study conducted at a hemotherapy centre in Recife, Pernambuco state, Brazil. A Cross-cultural adaptation was carried out by a committee of nine specialists, and we applied the PMQ to a pre-final sample of 40 individuals with sickle cell anemia, in addition to a sociodemographic and clinical questionnaire. RESULTS:The mean agreement indexes for PMQ equivalences were the following: semantic (0.996), idiomatic (0.970), experiential (0.991), conceptual (0.953), language clarity (0.991), practical relevance (0.906), and theoretical relevance (0.945). Assessment of the PMQ showed that 50% of participants obtained a score equivalent to medium risk of opioid abuse. Cronbach's alpha coefficient for the adapted PMQ instrument was 0.705, ranging from 0.641 to 0.736 among its items. CONCLUSION:The cross-cultural adaptation of the Pain Medication Questionnaire was satisfactory and easy to apply in the Brazilian population. It is clinically relevant, contributing professional practice and enlightening patients with sickle cell anemia on their behavioral dynamics with respect to opioid consumption. It will also contribute to teaching and research, because it is a useful tool for investigating the risk of abusive behavior in people with chronic pain.

Project description:According to the dual process model of coping, assimilative or accommodative strategies can be applied to deal with aversive life situations. In people with chronic pain, the tenacious focus on achieving analgesia is often referred to as assimilative coping and associated with more disability and catastrophic thinking. In contrast, accommodative coping (accepting one's pain and setting new goals) appears to have beneficial effects. To assess how people with chronic pain use these different coping strategies, questionnaires measuring these concepts are needed. Following international guidelines, a German version of the Pain Solutions Questionnaire (PaSol) was prepared. A sample of 165 participants with chronic low back pain (CLBP; 60% women; age 53 ± 8.4 years) filled in the questionnaire and measures for pain-related disability, affective distress, catastrophic thinking, and attention to pain. Item analyses, an exploratory factor analysis, and correlations with pain-related measures were calculated. In addition, data from 98 participants who received psychological treatment were examined to investigate the PaSol's sensitivity to change. The exploratory factor analysis reproduced the original questionnaire's four-factor structure. Internal consistencies for the subscales ranged from Cronbach's α=0.72 to α =0.84. Mean item difficulties for the subscales ranged from pi=0.62 to pi=0.79. The highest correlations were found for Meaningfulness with catastrophic thinking (r=-0.58) and affective distress (r=-0.36). The PaSol subscale Meaningfulness predicted pain-related disability; the subscales Meaningfulness and Solving Pain predicted affective distress. Furthermore, the PaSol was found to be sensitive to detect changes over time. The German version of the PaSol is a reliable and valid instrument in the measurement of assimilative and accommodative coping strategies in people suffering from CLBP. It may provide a useful tool when examining temporal dynamics of the changing coping strategies in the transition from acute to chronic pain as well as during pain treatments.

Project description:BackgroundThe Modified Low Back Pain Disability Questionnaire (MLBPDQ) is used for evaluating the functional disability in patients with low back pain (LBP). However, the measurement characteristics of the MLBPDQ among Arab patients are unknown. In this study, we aimed to translate and cross-culturally adapt the MLBPDQ into Arabic and evaluate its psychometric properties.MethodsAn Arabic version of the MLBPDQ was developed through forward translation, translation synthesis, and backward translation. Sixty-eight patients (55 males and 13 females) with a mean age 37.01 ± 7.57 years were recruited to assess its psychometric properties. Reliability was evaluated using internal consistency (Cronbach’s α), test retest reliability (utilizing intraclass correlation coefficient [ICC]), standard error of measurement (SEM), minimal detectable change at 95% confidence level (MDC95%), and 95% limits of agreement (LOA). The construct validity was investigated by correlating the new translation with four other measures of LBP (using Spearman’s rho). Finally, receiver operating characteristic curve was constructed to compute the sensitivity, using the area under the curve (AUC), and the minimum important change (MIC). An alpha level of 0.05 was set for statistical tests and all the psychometric values were tested against a priori hypotheses.ResultsThe culturally aligned MLBPDQ showed good internal consistency (Cronbach’s α = 0.85). The ICC, SEM, MDC95%, and LOA between baseline and two days later were 0.98, 1.60, 4.43, and -4.23 to 7.70, respectively, while the values between baseline and 14 days later were 0.94, 2.77, 7.67, and -6.59 to 13.53, respectively. The scale also demonstrated moderate to excellent correlation (rho = 0.54–0.86) with the other four questionnaires. The AUC value of the Arabic-MLBPDQ was 0.68, and the MIC was 3 points.ConclusionThe Arabic version of the MLBPDQ demonstrates adequate psychometric properties and can be used to assess disability level in patients with LBP in Arabic-speaking communities.
