Psychometric properties of the questionnaire about the process of recovery (QPR).

The latent structure, reliability and validity of the Questionnaire about the Process of Recovery (QPR) (Neil et al., 2009) were examined in a sample of participants with experience of psychosis (N=335). The original two factor model proposed by Neil et al. (2009) was examined using exploratory factor analysis followed by a further independent exploratory factor analysis to test revised solutions. Model fit statistics indicated that the most interpretable solution was a one factor model using 15 items from the original measure. Internal consistency, test re-test reliability and convergent validity of this new 15 item version were found to be high. Recommendations for the utility of the QPR in routine clinical practice along with suggestions for future research are discussed.
