In this issue of the Scandinavian Journal of Pain, Wood and coworkers  investigate the mediating role of catastrophizing in the relationship between changes in pain intensity and changes in depression in older adults. The study has a prospective design, thereby strengthening the same findings that were previously found by the authors in a cross-sectional design. The article addresses a fairly well studied topic, but in an understudied population. Few previous studies have specifically targeted the elderly population when trying to understand chronic pain mechanisms, despite the fact that there appears to be a difference between younger and older adults when it comes to the prevalence and characterization of comorbid depression in chronic pain [2,3]. The study therefore provides much needed knowledge about a topic with obvious clinical implications. More insight into the mechanisms of pain chronification could contribute to intervention development by guiding which elements to target specifically in treatment.1The unknown nature of the pain-depression relationshipIt has long been known that depression commonly co-occur in patients suffering from chronic pain, but the nature of this relationship is still largely unknown . When it comes to directionality and mediating variables, the scarce literature in study populations of older adults
