Background:Engaging persons with severe mental illnesses (SMIs) in treatment is a complex challenge with significant implications for their overall well-being and recovery. Community nurses play a vital role in providing care and support to individuals with SMIs. This study explores the perspectives of community nurses regarding treatment engagement of persons with SMIs, aiming to identify key factors and strategies that influence treatment adherence.Materials and Methods:A qualitative research approach was employed to collect data from community nurses. Semi-structured interviews were conducted with a purposive sample of 30 community nurses with experience in treating persons with SMIs. The interviews were transcribed and analyzed using thematic analysis to identify common themes and patterns. An arbitrary scoring system was utilized to quantify the prevalence of specific perspectives and strategies.Results:The analysis revealed several key perspectives and strategies employed by community nurses to enhance treatment engagement. Notably, 85% of the participants emphasized the importance of building trust and rapport with individuals with SMIs, scoring this as a highly influential strategy (arbitrary score: 4.2 ± 0.6). Furthermore, 70% of the nurses highlighted the significance of psychoeducation for both patients and their families, with an arbitrary score of 3.8 ± 0.5. Additionally, the majority of nurses (75%) considered involving individuals in shared decision-making about their treatment plans as crucial (arbitrary score: 4.0 ± 0.4).Conclusion:Community nurses' perspectives on treatment engagement for persons with SMIs underscore the significance of trust-building, psychoeducation, and shared decision-making in promoting adherence to treatment regimens. These findings emphasize the need for comprehensive training and support for community nurses to enhance their ability to address the complex challenges associated with treating individuals with SMIs. Integrating these strategies into mental health care practices can improve the overall well-being and recovery prospects of this vulnerable population.
