Research suggests that the way others react to a pain flare-up impacts on psychological and pain-related symptoms in chronic pain (CP). Experiencing validation from others is associated with less negative emotions and better functioning. Contrarily, experiencing criticism is linked to greater pain intensity and worse functioning. Nonetheless, studies are limited by an exclusive focus on spouses rather than significant other relationships, the use of proxy constructs (e.g. social support, responsiveness, solicitousness) rather than specific measures of validation and criticism and a focus on significant others' behaviour rather than patients' subjective experience. This study examines the psychometric properties of a new measure - Perceived Validation and Criticism in Pain Questionnaire (PVCPQ), and tests its contribution to functional impairment beyond pain intensity, sociodemographic and medical-related variables, positive and negative affect, safeness and compassion from others. ⋯ The current study provides a new 23-item measure of perceived validation and criticism by others in chronic pain that overcomes the limitations of existing measures. It adds to the literature by suggesting that perceived criticism (but not validation) contributes to functional impairment beyond sociodemographic variables, pain intensity, affect and related constructs such as social safeness and compassion from others. These results suggest that psychosocial interventions that aim to promote functioning in chronic pain should focus on the subjective experience of being criticized and validated by significant others.

Conditioned pain modulation (CPM) methods are experimental procedures to assess presumed descending nociceptive modulatory pathways. Various CPM-methods are currently used, making the comparison of results difficult. The aim of this study was to compare five conditioning stimuli and to evaluate the influencing effects of personal factors on CPM-efficacy. ⋯ Hot water immersion, cold pressor test, and single and double ischemic occlusion result in comparable CPM-effects at the mm. trapezius and quadriceps. Anti-nociceptive effects of the cold pack are mainly a result of attention towards the cold pack. Chronic stress, attentional focus towards the conditioning stimulus and perceived pain of the conditioning stimulus influenced the anti-nociceptive effects at the m. trapezius. Gender and level of physical activity influenced the anti-nociceptive effects with the other methods at the m. quadriceps.

Overactivity in the context of chronic pain (i.e. activity engagement that significantly exacerbates pain) is an important clinical issue that has gained empirical attention in the last decade. Current assessment concepts of overactivity tend to focus on frequency to quantify the severity of the pain behaviour. This study aimed to develop and validate a more comprehensive self-assessment, the Overactivity in Persistent Pain Assessment (OPPA). ⋯ This study deconstructs the overactivity concept and develop a corresponding assessment based on five quantifiable severity features: severity of pain exacerbation, maladaptive coping strategies used, impact on occupational performance, recovery time and frequency. Results of the psychometric evaluation indicate that this comprehensive assessment of overactivity severity features may be necessary to understand the impact of overactivity on pain severity and physical functioning from both a clinical and research perspective.

In past years, and mostly due to contextual psychological therapies, it has been argued that particular behavioural patterns may be useful in certain contexts, but not in others. The goal of this study has been to explore whether pain severity is indeed a contextual factor influencing the relationship between two controversial activity patterns, namely pacing and persistence, and functionality in people with fibromyalgia. ⋯ This manuscript shows that some activity patterns (i.e. pacing to conserve energy for valued activities) might be advisable regardless of pain levels. Conversely, some patterns might be especially recommended (i.e. pain-reduction pacing) or inadvisable (i.e. excessive and pain-contingent persistence) depending on pain levels (i.e. severe and mild pain, respectively).
