Comparison of an Online Mindfulness-based Cognitive Therapy Intervention With Online Pain Management Psychoeducation: A Randomized Controlled Study.

BACKGROUND: This study tested the effectiveness of a computerized mindfulness-based cognitive therapy intervention compared with computerized pain management psychoeducation in a randomized study. METHODS: Using an intention-to-treat approach, 124 adult participants who reported experiencing pain that was unrelated to cancer and of at least 6 months duration were randomly assigned to computerized mindfulness-based cognitive therapy ("Mindfulness in Action" [MIA]) or pain management psychoeducation programs. Data were collected before and after the intervention and at 6-month follow-up. RESULTS: Participants in both groups showed equivalent change and significant improvements on measures of pain interference, pain acceptance, and catastrophizing from pretreatment to posttreatment and the improvements were maintained at follow-up. Average pain intensity also reduced from baseline to posttreatment for both groups, but was not maintained at follow-up. Participants in both groups reported increases in subjective well-being, these were more pronounced in the MIA than the pain management psychoeducation group. Participants in the MIA group also reported a greater reduction in pain "right now," and increases in their ability to manage emotions, manage stress, and enjoy pleasant events on completion of the intervention. The changes in ability to manage emotions and stressful events were maintained at follow-up. CONCLUSIONS: The results of the study provide evidence that although there were equivalent changes across outcomes of interest for participants in both conditions over time, the MIA program showed a number of unique benefits. However, the level of participant attrition in the study highlighted a need for further attention to participant engagement with online chronic pain programs.

Willing and able: a closer look at pain Willingness and Activity Engagement on the Chronic Pain Acceptance Questionnaire (CPAQ-8).

UNLABELLED: An 8-item version of the Chronic Pain Acceptance Questionnaire (CPAQ-8) has recently been proposed and validated. The aims of this study were to further investigate the reliability and validity of the CPAQ-8 in a new sample. Questionnaires were completed by 550 people with chronic pain (478 online survey, 72 paper survey). A demographic and pain history questionnaire was administered along with the CPAQ-8 and measures of pain self-efficacy, pain catastrophizing, psychological flexibility in pain, anxiety, and mood. In addition, 105 respondents completed the CPAQ-8 within 6 weeks to provide test-retest reliability data. The 2-factor structure of the CPAQ-8 (Activity Engagement [AE] and Pain Willingness [PW]) was confirmed and had reasonable-to-good scale score reliability and test-retest reliability. Pain acceptance as measured by the CPAQ-8 was associated with less depression, anxiety, pain interference, fear of reinjury, pain catastrophizing, and psychological inflexibility in pain, and higher levels of satisfaction with life, pain self-efficacy, and general acceptance. Furthermore, pain acceptance fully mediated the relationship between reported pain severity and emotional distress (anxiety and depression) and partially mediated the relationship between pain severity and pain interference in a structural equation model. The test-retest reliability after 4 to 6 weeks ranged from .68 for PW to .86 for AE; the overall score correlation was .81. We conclude that the CPAQ-8 is a reliable and valid measure of pain acceptance and that the 2 subscales of the measure each make an individual contribution to the prediction of adjustment in people with chronic pain. PERSPECTIVE: The present study provides further evidence for the reliability and validity of the CPAQ-8. Support was found for the 2 related subscales, PW and AE, which appear to work in synergy to influence levels of pain interference and emotional distress in people living with chronic pain.

Validation of the chronic pain acceptance questionnaire (CPAQ) in an Internet sample and development and preliminary validation of the CPAQ-8.

This study investigated the psychometric properties of the Chronic Pain Acceptance Questionnaire (CPAQ) in a mixed chronic pain, Internet sample and sought to develop a valid and reliable short form. Questionnaires were completed by 428 respondents, comprising a sample accessed via the Internet (n=319) and a sample who completed a paper and pencil version of the measures (n=109). Using confirmatory factor analysis (CFA) the two-factor structure of the CPAQ in the Internet sample was supported, though a good model fit was only achieved following the removal of one item. The resultant 19 item CPAQ demonstrated good reliability and evidence of validity was obtained for this sample. Data from the Internet sample were used to derive an eight-item short form. The two four-item factors (activity engagement [AE] and pain willingness [PW]) were confirmed using CFA and found to be invariant across both samples with good scale reliability. Higher CPAQ-8 and subscale scores were correlated with less depression and anxiety, pain severity and pain interference, and fewer medical visits for pain. Using structural equation modelling both subscales were found to partially mediate the impact of pain severity on pain interference and emotional distress. In this model AE had stronger associations with outcomes while PW accounted for a small portion of the variance in pain interference and anxiety, but not depression. This study confirmed the two-factor structure of the CPAQ in a mixed chronic pain Internet sample and provides preliminary evidence for the psychometric soundness of the CPAQ-8.
