- Single case designs (SCDs) represent an excellent approach for developing and testing treatments, and for generating general knowledge of treatment mechanisms and outcomes. Their ability to generate knowledge, however, will depend on their methods being reliable, valid, clearly described, and replicable. This scoping review aims to map assessment methods in SCD studies of psychological treatments for chronic pain. The particular aims were to review the specific measures used, their modes of administration, their adequacy as measures, and opportunities for improvement. PubMed, PsycINFO, CINAHL and OpenGrey were searched for SCD studies of psychological treatments for chronic pain in adults. Two reviewers independently assessed eligibility, with input from two additional reviewers, and then extracted relevant data from the 55 included studies. The most common outcome domains were “pain”, “physical functioning” and “psychological processes.” Non-behavioral measures were more common than behavioral or physiological measures. Measures were often standardized. Measures in each domain were highly varied, and administration information was lacking. Evi dence for adequacy of measures was based on psychometric analyses of aggregated group data for nonbehavioral measures and agreement for behavioral and physiological measures, but was frequently not re ported. Non-behavioral idiographic measures were often inadequate in that adapted measures were often used but validation was reported for original versions. Outcome domains did not correspond with currently available guidelines for measures employed in clinical trials in pain. A new set of guidelines, that is more suited to psy chological treatments and to SCDs, is needed. Researchers should consider following an idiographic framework by using individualized measures more often. When measures are individually applied, it is recommended that their adequacy is not based on nomothetic psychometric approaches. Rather, behavioral assessment principles should be employed. Overall, adequacy reporting, usage of SCD consistent terminology, and information on how measures are administered need improvement.

- BackgroundPeople with chronic pain are frequently exposed to stigma, which is typically distressing and may lead to internal stigmatizing thoughts. The thought content associated with stigma has similarities to pain catastrophizing, although these concepts differ in that stigma is arguably more social in origin. Stigma can be measured by the Stigma Scale for Chronic Illness – 8-item version (SSCI-8). In this study, we first demonstrate the validity of this measure in Swedish. We then examine the role of stigma in the health and functioning of people with chronic pain, particularly beyond the role played by pain catastrophizing.MethodsAdult participants (N = 404) with chronic pain recruited online completed measures of pain, stigma, catastrophizing, pain interference, work and social adjustment and depression on two occasions.ResultsA one-factor solution had an overall good model fit as long as residuals were allowed to covary, indicating some redundancy in the items. The SSCI-8 demonstrated good internal consistency and moderate temporal stability, and SSCI-8 scores demonstrated medium-to-large correlations with the measures of health and functioning. Furthermore, stigma was found to significantly contribute to explained variance in pain interference, work and social adjustment and depression, uniquely adding to the explained variance in these outcomes even after accounting for pain catastrophizing.ConclusionsThe SSCI-8 provides an adequate measure to capture stigma experiences. Stigma is uniquely associated with pain-related outcomes and should be further considered in pain research and clinical practice in the future.SignificanceThis study points to the importance of a social perspective on pain-related outcomes. We may need to more fully appreciate the way that people with chronic pain are treated by both health care providers and others can have an impact on their well-being. Potential negative impacts of stigmatizing responses to people with chronic pain are highlighted by the current results.

- ObjectivesProcesses of psychological flexibility (PF) are positively associated with health and wellbeing in several chronic pain disorders. However, these processes have not been investigated in endometriosis, a chronic pain disorder affecting 5–10 % of women worldwide. This study is a preliminary investigation of the associations between PF or psychological inflexibility (PI) and daily functioning in people with a primary diagnosis of endometriosis.MethodsThis study is based on a secondary analysis of survey data from Swedish-speaking adult participants with chronic pain recruited online. The current study included only those reporting a diagnosis of endometriosis and significant long-term pain. All participants completed the Multidimensional Psychological Flexibility Inventory (MPFI), a measure of PF and PI, as well as other measures of PF, and measures of pain and daily functioning. Correlation and multiple regression analyses were performed to examine relations of PF and PI with measures of pain and daily functioning.ResultsIn general, PF facet scores from the MPFI did not correlate with pain interference but did correlate with depression, with the exception of acceptance. The overall facets of PI appeared to perform better as correlates and in regression. Established measures of PF performed in correlation and regression analyses generally as has been observed in other chronic pain populations, with significant positive associations.ConclusionsIn this preliminary analysis of PF and PI in participants with endometriosis-related pain, these processes appear relevant, especially in understanding depression, but results varied along with the measures used. Specifically, when employing the MPFI, the PI facets emerged as stronger correlates. The findings underscore the potential benefit of incorporating assessments of PF and PI as process variables in endometriosis-research, but also that careful consideration should be given when selecting instruments.
