Opioid misuse is mediated by affective states in chronic pain patients

Chronic pain is closely associated with psychological comorbidities, including anxiety and depression, as well as substance use disorders, particularly alcohol use disorder and opioid use disorder. Recent research highlights the bidirectional nature of these relationships, suggesting that each of these variables can contribute to the onset and exacerbation of the others. The present study aims to examine whether negative affective states associated with chronic pain are linked to risk-related patterns of opioid and/or alcohol consumption in individuals suffering from chronic pain. To this end, a comprehensive battery of standardized instruments was administered to assess subjective pain intensity, anxious-depressive symptomatology, and substance use risk patterns for opioids and alcohol. The findings reveal a strong positive correlation between subjective pain levels, anxious-depressive symptoms, and opioid risk-taking behaviors. Notably, individuals with elevated scores on measures of anxiety and depression reported higher levels of subjective pain and demonstrated greater risk-taking behavior related to opioid use, compared to those with lower symptomatology scores. In conclusion, this study underscores chronic pain as a significant risk factor for the development of anxious-depressive disorders and opioid misuse. These findings highlight the importance of integrating psychological and substance use assessments in the management of chronic pain to inform targeted interventions and preventative strategies.
