TY - JOUR AU - B. King AU - Y. Suchil AU - O. E. Adepoju AU - W. Liaw A1 - AB - Medical-legal partnerships (MLPs) address social determinants of health by integrating legal services into health care settings. This study examines associations between health-harming legal needs (HHLNs) and mental health quality among family medicine clinic patients screened for MLP referral. A retrospective cohort of 475 patients completed an HHLN screening instrument, including a measure of mentally unhealthy days (MUDs). Zero-inflated negative binomial models assessed associations between HHLNs and MUDs, adjusting for demographics. Patients with any HHLN had 65% lower odds of reporting zero MUDs. Worrying about housing instability was the strongest independent predictor of increased MUDs, associated with a 56% increase. Black race was associated with greater odds of reporting zero MUDs. Housing concerns are a key driver of mental health quality, highlighting the need for targeted legal interventions. Integrating MLP screening into primary care may help identify and address legal issues impacting patient mental health.
