We argue that in all randomized controlled trials that investigate treatments for chronic pain emotional distress should be reported. In a majority of cases, pain intensity and pain-related disability are measured, yet-despite guidelines to the contrary-pain-related distress is not included. We suggest that the new extension code for chronic pain as incorporated in the ICD-11 will be well suited to fill this gap at minute additional effort for the participants.

Children of parents with chronic pain are a high-risk group to develop own chronic pain. There is evidence that parental responses such as catastrophizing and solicitousness play an important role in the familial transmission of chronic pain. However, little is known about factors that modulate these responses. Based on the literature, we assumed that top-down processes, such as parent chronic pain and anxiety, would be associated with increased catastrophizing and solicitousness. Bottom-up processes, such as child chronic pain and anxiety, were assumed to moderate this association. ⋯ This study increases our knowledge on modulating factors on maladaptive parental reactions such as parental pain-related catastrophizing towards their children in pain. According to our findings, it is not the child variables, that is (parental perception of) child chronic pain or anxiety that modulate parental reactions but parent factors, particularly parent anxiety. Thus, parent anxiety should be regularly assessed and addressed during pain treatment of adult populations, and in interventional studies in children with chronic pain and their parents with chronic pain and anxiety symptoms.

Ample evidence suggests that individuals with borderline personality disorder (BPD) exhibit hyposensitivity to pain. Since the underlying mechanism of the pain hyposensitivity is unknown, we tested here for the first time whether this hyposensitivity is pain specific or exists also for innocuous sensation, and whether it is associated with enhanced descending pain modulation capabilities. ⋯ On the basis of testing pronociceptive and antinociceptive components among individuals with BPD and healthy controls, this study reveals enhanced ability to inhibit pain among woman with borderline personality disorder (BPD) which may underlie hyposensitivity to both noxious and innocuous stimuli and perhaps also self-injurious behaviour among these individuals. The study contributes novel information on possible mechanisms involved in BPD manifestations.
