Quality of life

What is quality of life?

Quality of life (QoL) refers to an individual’s sense of satisfaction with their circumstances. This can be measured subjectively via interview and objectively via measures of overall health, social and material well-being and access to resources and opportunities. A key focus of QoL research in schizophrenia is to identify factors that influence or predict a person’s satisfaction with their circumstances, which may then provide targets for therapeutic focus to improve QoL.

What is the evidence for quality of life?

Moderate to high quality evidence finds small to medium-sized associations between worse symptom severity and poorer QoL. Moderate to low quality evidence finds the best predictors of better well-being are engagement in meaningful leisure activities and having strong social networks.

On objective QoL rating scales, there are small associations between better QoL and better verbal ability, vigilance, short-term or working memory, processing speed, and executive functioning. On subjective QoL rating scales, there is a small association between better QoL and better letter fluency, but poorer verbal ability, and slower processing speed.
