Perceived Mental Health Service Priorities among Social Service Personnel in South Korea: An Importance–Performance Analysis by Depression Severity

Technical Summary: Perceived Mental Health Service Priorities among Social Service Personnel in South Korea

Problem Statement
Social Service Personnel (SSP) in South Korea represent a distinct population of young men assigned to civilian institutions (e.g., healthcare, social welfare) as supplementary service personnel due to physical or mental health vulnerabilities identified during conscription. Despite comprising a significant portion of the conscription pool (with depression accounting for 34.6% of SSP classifications in 2023), there is limited empirical evidence regarding how this group perceives the availability and adequacy of mental health services. Existing support systems often operate under a uniform model, yet it remains unclear whether current services align with the specific needs of SSPs, particularly when stratified by the severity of depressive symptoms. The study addresses the disconnect between service availability and actual utilization, noting that structural barriers, stigma, and role ambiguity in civilian assignments may hinder help-seeking behaviors.

Methodology
The study employed a cross-sectional survey design utilizing data from 201 SSPs who participated in the 2025 Mental Health Support Program survey conducted by the Korea Human Resource Development Institute for Health and Welfare.

• Participants: The sample consisted of voluntary participants aged 20 or older, recruited nationwide via institutional notices. After excluding incomplete responses, the final analytical sample included 201 individuals.
• Measures:
  • Service Perception: Perceived importance and performance of 11 specific mental health services were assessed using a 4-point Likert scale (0–3). Services were categorized into three domains: Military-related services (Military Manpower Administration and assignment institution counseling), Youth services (counseling for those ≤24), and Public mental health services (community centers, addiction support, suicide prevention, psychiatric care, peer support, and housing).
  • Depression Severity: Assessed using the Korean version of the Patient Health Questionnaire-9 (PHQ-9). Participants were stratified into three groups: No or minimal symptoms (0–4), Mild symptoms (5–9), and Moderate-to-severe symptoms (≥10).
• Analysis: The study utilized Importance–Performance Analysis (IPA), a framework originally developed for marketing strategy, to map services into four quadrants based on mean scores of importance and performance. This allowed for the identification of service priorities (e.g., "Concentrate here" for high importance/low performance) across the total sample and specific depression severity subgroups.

Key Results
The analysis revealed that while core services (counseling, psychiatric treatment, suicide prevention) were generally rated high in both importance and performance, significant variations emerged when analyzing data by depression severity.

• Overall Sample: Most services fell into Quadrant 1 ("Keep up the good work") or Quadrant 3 ("Low priority"). This suggests that, broadly, SSPs perceive the current system as reasonably aligned with needs, though some areas lack urgency.
• No or Minimal Symptoms (PHQ-9 0–4): This group identified peer support respite services as a priority for improvement (Quadrant 2: High Importance/Low Performance). Conversely, general mental health support services provided by the Military Manpower Administration were rated as high performance but lower importance (Quadrant 4: "Possible overkill").
• Mild Symptoms (PHQ-9 5–9): For this group, youth counseling and support center services emerged as a critical gap (Quadrant 2), indicating they are viewed as highly important but currently underperforming.
• Moderate-to-Severe Symptoms (PHQ-9 ≥10): This group exhibited the largest discrepancies. They reported significant gaps in public mental health services (e.g., mental health welfare centers, counseling vouchers), placing them in the "Concentrate here" quadrant. Notably, this group rated the importance of these services lower than the other groups, yet the performance gap remained substantial, suggesting unmet needs that may be exacerbated by structural barriers.

Key Contributions

1. Severity-Responsive Prioritization: The study demonstrates that mental health service priorities are not static but vary significantly based on the severity of depressive symptoms. A uniform service model fails to address the specific gaps experienced by different subgroups (e.g., the need for peer respite in low-symptom groups vs. the need for accessible public health services in high-symptom groups).
2. Identification of Structural Gaps: By applying IPA to a compulsory service population, the research highlights specific service domains where performance lags behind perceived importance, particularly for those with moderate-to-severe depression who face barriers in accessing community-based care.
3. Application of Andersen Behavioral Model: The study conceptualizes depression severity as a critical "need factor" that shapes service perceptions, providing a theoretical basis for understanding why service utilization may remain low despite availability.

Significance and Claims
The paper claims that mental health support for SSPs in South Korea must transition from a uniform, internally focused model to a coordinated and severity-responsive service framework. The authors argue that while specialized services are performing well, there is a critical need to strengthen referral pathways and inter-organizational coordination among the Military Manpower Administration, service assignment institutions, and community-based providers.

Specifically, the study suggests:

• Differentiated Interventions: Preventive, low-threshold interventions (like peer respite) should target those with mild or no symptoms, while proactive case management and navigation are essential for those with moderate-to-severe symptoms to overcome structural and administrative barriers.
• Systemic Coordination: Improving continuity of care requires clear referral mechanisms that reduce stigma and administrative friction, ensuring that individuals with higher depressive severity can access appropriate psychiatric and community support without delay.

The authors maintain a modest tone, acknowledging that their findings reflect subjective perceptions rather than objective service effectiveness and that the cross-sectional nature of the data precludes causal inferences. However, they posit that these perceptual gaps offer actionable insights for policy reform to better serve a vulnerable population within the compulsory service system.
