Comparison of instruments for measuring the quality of life impairment syndrome in severe mental disorders

Q-LES-Q versus QLS and LQOLP
  • Michael S. Ritsner
Chapter

Abstract

In the present chapter, we compared the psychometric properties of the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) with the Quality of Life Scale (QLS) and the Lancashire Quality of Life Profile (LQOLP) in the same patients with schizophrenia, schizoaffective, and mood disorders. These instruments were chosen since they are mental illness-related, and Q-LES-Q is a self-report evaluation scale, whereas QLS is observer-rated, and LQOLP has domains similar to Q-LES-Q, which enables a comparison of the instruments. The compared instruments proved to be mental health-related, but none were mental-disorder-specific. Despite the acceptable psychometric properties and the correlation of the general indices, similar domains proved to be instrument-specific and were not sufficiently compatible. These discrepancies should be considered when comparing evaluations from similar domains in these scales
