Substance Use in Relation to Mental Illness: A Study of Mexican-Origin Latinos with Schizophrenia and Their Family Members.

Little is known about family context and substance use behaviors among Latinos with schizophrenia. Learning about patient and family caregiver perceptions of use is critical to our understanding of how best to support these vulnerable patients and family caregivers. This study explored perceptions of substance use in relation to mental illness among Latinos primarily of Mexican origin with schizophrenia and their family caregivers. Semistructured interviews were conducted with 34 participants (20 family caregivers; 14 patients) with direct and indirect substance use experience, in their preferred language. Data were analyzed using thematic analysis, which consisted of comparing codes across and within patient and family caregiver transcripts. Findings revealed that substance use affected well-being, particularly patient recovery and caregiver burden. Strategies to address well-being included limiting substance use, being vigilant about patient use, and communicating the negative impact of use. The environmental impact and stigma of substance use were major contextual challenges. Patients addressed these by limiting their socialization. Family social context was important to how substance use was perceived and managed by patients and caregivers. As such, treatment models should consider a holistic perspective that incorporates family context when addressing substance use among Latinos with schizophrenia.
