Quality of Life Assessment in Severe Mental Illnesses

Quality of life (QoL) assessment has emerged as a cornerstone of contemporary psychiatric research and clinical practice, particularly for individuals living with severe mental illnesses such as schizophrenia, bipolar disorder and major depressive disorder. Beyond symptom reduction, QoL measures capture subjective well-being, social participation and functional capacity across multiple life domains including interpersonal relationships, occupational engagement, physical health and self-perception. Instrumentation has evolved from generic health surveys to disorder-specific scales, enabling a nuanced appraisal of the lived experience of severe mental illness. Methodological innovations such as individual patient data meta-analyses and longitudinal cohort designs have clarified the interplay between clinical symptoms, cognitive impairment, medication side effects and socioeconomic factors in shaping QoL trajectories. Cross-cultural validation of QoL instruments underscores the global relevance of patient-centred outcomes and supports the development of interventions that target both clinical remission and domain-specific satisfaction. Importantly, patterns of domain-level dissatisfaction have been linked to relapse risk, highlighting the prognostic value of routine QoL monitoring. Integrating QoL assessment into multidisciplinary care models fosters personalised treatment plans, promotes recovery-oriented practice and aligns therapeutic goals with patient priorities. As research continues to refine measurement frameworks and identify modifiable determinants, QoL assessment stands poised to guide resource allocation, inform policy and enhance quality assurance in mental health services worldwide.
