RESUMEN
Prescription-related opioid misuse, especially in chronic pain populations, is an ongoing problem and is related to increased mortality. The purpose of this study was to assess the utility of two restructured scales of the MMPI-2-RF: the Personality Psychopathology Five (PSY-5-RF) and the Higher-Order Scales to determine which of their subscales may be beneficial for identifying the risk of opioid misuse in a chronic pain population. A sample of 136 patients with chronic disabling occupational musculoskeletal disorders completed the MMPI-2-RF and the Current Opioid Misuse Measure (COMM) upon admission to a functional restoration program. The PSY-5-RF and H-O subscales were correlated with the baseline COMM scores. Correlation analyses, ROC curve analyses, and multiple binary logistic regression models were developed to determine which subscales were most associated with elevated COMM scores. The results of the regression analyses suggest that Scale elevations on two of the PSY-5-RF Scales and two Higher-Order Scales of the MMPI-2-RF demonstrated significant associations with elevated COMM scores, thus exhibiting the utility of these subscales in identifying the risk of opioid misuse among chronic pain patients. These findings are clinically meaningful in underscoring the importance of identifying specific personality traits as potential predictors of opioid misuse, and identifying those at risk through careful screening. Clinical implications based on each of the PSY-5-RF and H-O scales significantly associated with elevated COMM scores are discussed.

OBJECTIVE: The aim of this study was to identify demographic and psychosocial variables associated with successful completion of a functional restoration program and return-to-function within 3 months of treatment completion. METHODS: Three hundred seven patients admitted to the functional restoration program were evaluated for completion status and 200 patients with valid data were assessed for 3-month return-to-function status following completion. Psychosocial and functional status was assessed at baseline. RESULTS: Key factors associated with program completion included lower perceived disability, lower pain, lower functional impairment, and lower fear avoidance. Factors associated with 3-month return-to-function included lower perceived disability, lower depression, greater belief that pain is not associated with impairment, and higher quality of life. CONCLUSIONS: Psychosocial and functional factors contribute to both functional restoration completion and 3-month return-to-function outcomes.

OBJECTIVE: We investigated the extent to which anxiety and depression mediate the relationship between pain catastrophizing and the risk of prescription opioid misuse in chronic pain patients. METHODS: 215 patients with chronic occupational musculoskeletal disorders completed self-report measures upon admission to a functional restorational program. A bootstrap multivariate regression analysis was conducted to assess how depression and anxiety mediated the relationship between pain catastrophizing and prescription opioid misuse. RESULTS: Catastrophizing, anxiety, and depression predicted higher risk for prescription opioid misuse. Furthermore, anxiety and depression acted as mediators while controlling for the effects of gender and age. Finally, it was found that the effects of catastrophizing on risk for prescription opioid misuse were completely eliminated by those of depression. CONCLUSION: Due to the partially independent relationship of anxiety and catastrophizing, it is recommended that treatments for chronic pain patients employ techniques addressing both behaviors. The relationship between depression and catastrophizing requires more research since it was observed that their effects were confounded.
