Literature has shown that individuals with various psychiatric disorders experience a lower quality of life (QoL). However, few have examined QoL across disorders. The current study explored differences in QoL and symptom severity across 4 psychiatric diagnostic groups: anxiety disorders (including obsessive compulsive disorder [OCD]), depressive disorders, schizophrenia, and pathological gambling. Materials and Methods: Data analysed was from a previous study that examined the prevalence of hoarding symptoms among outpatients (n = 500) in a tertiary psychiatric hospital in Singapore. Measures utilised included the Beck Anxiety Inventory (BAI), Beck Depression Inventory-II (BDI-II) and Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF). Sociodemographic information and details on type and number of comorbidities were also collected. Results: The depressive disorder group had the highest level of depressive and anxiety symptoms and the lowest QoL whereas; the schizophrenia group had the lowest level of depressive symptoms and the highest QoL. Age and employment status were the only sociodemographic correlates which were significantly associated with QoL. After controlling for sociodemographic factors, only the type of mental disorder was found to have a significant effect in explaining BAI, BDI-II and Q-LES-Q-SF. Conclusion: Findings offer insight in terms of the burden associated with the various disorders.
Quality of life (QoL) can be defined as an “individual’s perception of their position in life…in relation to their goals, expectations, standards and concerns”. Assessing the QoL of an individual is invaluable as it looks beyond the “direct manifestations of an illness” to examine its effects on the individual’s daily life and life satisfaction.
