Introduction Healthcare quality, crucial amidst rising mental disorders, faces integration challenges due to undefined parameters. Patient satisfaction correlates with improved outcomes, guiding service quality assessment. Family dynamics impact chronic schizophrenia outcomes; research gaps exist in first-episode psychosis dynamics. Early family interventions show promise in enhancing social functioning during psychosis onset. Purpose This study aims to investigate factors influencing family member satisfaction with mental health services for clients with mental health issues. Using the SATIS-BR scale by WHO, satisfaction across three subscales will be measured. Methodology This cross-sectional correlation study investigates factors affecting family member satisfaction with mental health services for clients with mental health issues. Using the SATIS-BR scale by WHO, satisfaction is measured across three subscales. 101 family members from a mental health center participated. Exclusion criteria included participants unable to comprehend the scale despite clarification, indicating potential mental confusion. Results This study, based on a sample of N=101 participants, examines caregiving experiences for mentally disordered family members and perceptions of mental health services. Demographic analysis reveals a diverse representation across gender, marital status, education, and employment. While most participants expressed satisfaction with mental health services and perceived active involvement from mental health teams, over half reported feeling stigmatized. Gender and residence differences were minimal, though rural residents reported higher satisfaction. Stigmatization correlated with lower treatment satisfaction. Tailored support services are crucial to address caregiver burden and combat societal stigma in mental health care. Conclusion This study emphasizes the vital role of family caregivers in mental health support and stresses timely interventions for them to improve patient outcomes. It also underscores the necessity of tackling stigma, fragmented services, and resource limitations to enhance patient and caregiver satisfaction with mental health services, highlighting the importance of holistic approaches to care.
