Situational confidence, that is, confidence to resist substance use in high-risk situations, and recovery capital (RC) are resources that individuals can draw upon to initiate and sustain their recovery from opioid use disorder. We assessed the associations between total, social, and personal RC and situational confidence among recovery residents taking medications for opioid use disorder. Cross-sectional associations between the Brief Situational Confidence Questionnaire and Assessment of Recovery Capital scores were assessed among participants (N = 267) enrolled in a longitudinal study in 13 recovery homes for persons taking medications for opioid use disorder in Texas using χ 2 tests and multivariable logistic regression. Most participants were 35 years or older (51.7%), male (59.4%), non-Hispanic White (71.5%), and unemployed (66.0%); used more than one substance (77.9%); and had higher educational levels (53.8%). The majority had high situational confidence (66.7%), social (63.7%), physical (67.0%), and total (64.8%) RC. Education (model 1: adjusted odds ratio [aOR], 1.96; confidence interval [CI], 1.13-3.40; model 2: aOR, 2.03; CI, 1.17-3.51) and social (aOR, 2.08; CI, 1.11-3.92), personal (aOR, 2.06; CI, 1.08-3.93), and total (aOR, 2.98; CI, 1.71-5.20) RC were associated with situational confidence. Our findings highlight the need for recovery housing operators to be trained on the relevance of RC and situational confidence to practice to improve recovery outcomes among residents with opioid use disorder. Health planners, recovery housing administrators, and policymakers should strengthen recovery residence-based services and systems to improve individual RC and situational confidence.
