Pain Catastrophizing and Substance Misuse: A Scoping Review of the Literature.

BACKGROUND

Pain catastrophizing, or the interpretation of pain as unbearable or intolerable, can increase pain-related anxiety and severity. High levels of pain catastrophizing have also been linked to substance use, particularly for substances with analgesic properties. Importantly, behavioral treatments can reduce pain catastrophizing, making them promising interventions for mitigating pain-related substance use. The aim of this scoping review is to summarize literature investigating the relationship between pain catastrophizing and substance use in adults.

METHODS

We performed a scoping review of peer-reviewed literature. Included articles had both a measurement of pain catastrophizing and substance use, and reported analyses characterizing the relationship between the two.

RESULTS

Of the 341 abstracts identified, 47 articles met eligibility criteria. Most studies focused on people with chronic pain. Some studies also considered samples with substance use disorders (with and without chronic pain) or acute pain, and general population samples. There was generally a positive association between pain catastrophizing and substance misuse; this association was consistent across multiple samples and substances. Most studies were cross-sectional, although associations were also detected in longitudinal studies. The magnitude of associations tended to be stronger for higher severity substance use and more proximal tests of association. More longitudinal and experimental studies are needed, however, to better delineate these effects.

DISCUSSION: Findings indicate a consistent positive association between pain catastrophizing and substance use, highlighting the potential for interventions targeting pain catastrophizing to reduce negative substance-related consequences.
