Perceived injustice in fibromyalgia: psychometric characteristics of the Injustice Experience Questionnaire and relationship with pain catastrophising and pain acceptance.

To validate a Spanish version of the Injustice Experience Questionnaire (IEQ), a measure of perceived injustice, in a fibromyalgia sample and to examine its relationship with pain catastrophising and pain acceptance. The IEQ was administered along with the Pain Visual Analogue Scale, the Fibromyalgia Impact Questionnaire, the Hospital Anxiety and Depression Scale, the Pain Catastrophizing Scale (PCS) and the Chronic Pain Acceptance Questionnaire (CPAQ) to 250 primary care patients with fibromyalgia. The IEQ had good test-retest reliability (intraclass correlation coefficient=0.98) and internal consistency (Cronbach's α=0.92). The factor structure obtained was similar to the original validation study. The multiple regression analyses showed that perceived injustice (PI) accounted for significant pain-related outcomes after controlling pain intensity, PCS and CPAQ. Principal component analysis of both the IEQ and the CPAQ taken together showed that the two constructs do not represent opposite extremes of the same dimension. The IEQ is a reliable assessment tool for measuring PI among patients with fibromyalgia. PI seems to be distinct from catastrophising, although the two constructs are very similar. The factor analysis showed that PI and acceptance represent related constructs, and this entails relevant implications for therapy, as acceptance-based interventions would be appropriate.

Adolescent acceptance of pain: confirmatory factor analysis and further validation of the chronic pain acceptance questionnaire, adolescent version.

Preliminary reports suggest that acceptance of pain is an important construct when assessing and treating adolescents with chronic pain. Although the Chronic Pain Acceptance Questionnaire, Adolescent version (CPAQ-A) appears to be a promising tool, it has been evaluated in only 1 study. The current results present a confirmatory analysis of the CPAQ-A and validity data collected independently from the developers of the scale. A sample of 109 adolescents with chronic pain completed the CPAQ-A, as well as measures of pain characteristics, functional impairment, depression, anxiety, and pain self-efficacy. Results of the confirmatory factor analysis indicate the previously reported 2-factor solution provides a good fit to the data, and has acceptable internal consistency. The CPAQ-A correlated strongly with disability, depression, anxiety, and self-efficacy. It correlated only moderately with pain intensity and was not correlated with pain frequency or duration of pain. When entered last into a hierarchical regression model predicting disability, acceptance accounted for more variance than pain intensity, depression, anxiety, and self-efficacy. Results supported the internal consistency and validity of the CPAQ-A as a measure of pain acceptance in this sample of adolescents with chronic pain. Use of the CPAQ-A may provide valuable insight into the manner in which adolescents adapt to chronic pain and can guide acceptance-based treatment. This article strengthens the psychometric support for a measure of chronic pain acceptance in adolescents. Acceptance-based treatment has been shown to reduce disability in preliminary research targeting adolescents with chronic pain; the CPAQ-A may be useful for assessing the degree to which acceptance-based approaches may be indicated for a given patient.
