Mediation analysis of severity of needs, service performance and outcomes for patients with mental disorders

Abstract

BackgroundNeeds and service performance assessment are key components in improving recovery among individuals with mental disorders.AimsTo test the role of service performance as a mediating factor between severity of patients' needs and outcomes.MethodA total of 339 adults with mental disorders were interviewed. A mediation analysis between severity of needs, service performance (adequacy of help, continuity of care and recovery orientation of services) and outcomes (personal recovery and quality of life) was carried out using structural equation modelling.ResultsThe structural equation model provided a good fit with the data. An increase in needs was associated with lower service performance and worse outcomes, whereas higher service performance was associated with better outcomes. Service performance partially mediated the effect of patient needs on outcomes.ConclusionsPoorer service performance has a negative impact on outcomes for patients with the highest needs. Ensuring more efficient services for patients with high needs may help improve their recovery and quality of life.
