Severe mental illnesses (SMI), including schizophrenia and bipolar disorder, encompass distinct diagnostic criteria and varying degrees of disability. These conditions may also result in atypical behaviors, such as experiencing hallucinations (
1). These disorders can lead to considerable distress not only for the individuals affected but also for their families and those in their social circles over the long term. Until the 1970s, the predominant approach to treating patients with severe mental disorders involved institutional care within health facilities (
2). The deinstitutionalization movement arose to downsize and eventually shut down large care facilities. Instead, it aimed to provide community support, driven by these institutions’ inadequate performance in effectively caring for individuals (
3). Global standards, through a holistic approach, advocate for the enhancement of community-based services (

4,
5). In numerous countries, a diverse array of community-based mental health interventions is employed to manage these disorders. These include crisis services, community outreach programs, peer support initiatives, hospital-based services, supported living arrangements, and community mental health centers (CMHCs) (
6-
10). Integrating mental health services at the community level offers numerous advantages, such as enhanced accessibility, cost efficiency, improved treatment adherence, and better clinical outcomes. Furthermore, delivering these services within the community significantly contributes to raising public awareness about mental health, diminishing stigma and discrimination, and fostering the social inclusion of individuals with SMI (
10). Different countries have different approaches to their mental health, which are constantly changing and tailored to their existing situations, goals, and policies. In Iran, a crucial approach to community-based mental health services is the incorporation of these services into the national healthcare framework, particularly within the primary healthcare system, to improve accessibility. Although this initiative has shown success in rural regions, it has fallen short of expected results in urban environments (
11). The 2011 Iran Mental Health Survey (IranMHS) revealed that 23.6% of adults, approximately one in four, experience psychiatric disorders.
Alarmingly, over two-thirds of these individuals remain unrecognized and untreated. Furthermore, many of the available mental health services are either inadequate or of substandard quality (
12). Over the past three decades (1990 - 2019), Iran has experienced a significantly higher burden of mental disorders, recorded at 77%, compared to the global increase of 55%. This disparity is primarily linked to shifts in population size and structure, highlighting an escalating demand for mental health services across primary, secondary, and tertiary care levels (
13). To enhance urban mental health, the establishment of community-based mental health centers was proposed and subsequently approved by the mental health department of the Ministry of Health and Medical Education (MOHME). The first of these centers was inaugurated in Tehran in 2010 (
14). The primary characteristics of these centers include comprehensive care that encompasses prevention, diagnosis, treatment, and rehabilitation for patients, minimizing the need for psychiatric hospitalization. In 2015, the Ministry of Health incorporated the CMHC service model into the SERAJ program, a comprehensive mental and social health initiative aimed at Iranian communities, recognizing its effectiveness and the high level of patient satisfaction it achieved (
12). Consequently, the services provided by CMHC have been enhanced to incorporate rehabilitation programs specifically designed for individuals with SMI (
15). The CMHC program is presently being piloted in several cities across the country (
16). The CMHC was created to improve rehabilitation services for people with SMI. However, these centers face major challenges, such as not having enough staff and limited funds, which make it hard for them to provide ongoing services (
15). In medium and large cities, mental health services are predominantly offered by hospitals and clinics rather than primary care, primarily due to the insufficient number of CMHCs. Additionally, there is a notable lack of coordination among various service providers (
14). Studies indicate that the implementation and evaluation of community-based mental health services pose significant challenges for numerous national healthcare systems, primarily due to constraints in resources, including financial and professional limitations (
17,
18).
Another study identify several significant challenges in delivering services in Iran. These include a limited understanding of care needs, insufficient knowledge regarding mental disorders, discrimination, inadequate access to services, and high costs. Tackling these issues is crucial for enhancing the quality of service delivery (
13). Addressing this issue in Iran is especially crucial given the significant population that requires this type of service (
19,
20). The aforementioned materials emphasize the need to fill research gaps in mental health policies. They highlight the importance of analyzing current policies, allocating resources (financial and human), and training programs for mental health workers, understanding patients’ needs and their families, adequacy and satisfaction with existing services and treatments, or the need for unconventional treatments.
