title: Validation of the Routine Assessment of Patient Progress (RAPP) in patients with psychosis in South India.
abstract: The aim of the study was to validate the Routine Assessment of Patient Progress (RAPP), an instrument for assessment by nurses, among patients with psychosis in South India. One hundred consecutive patients with psychosis admitted to the Department of Psychiatry, Christian Medical College, Vellore, India, were assessed on day five and day 19 using the RAPP, the PANSS, and the CGI scales. The correlation of the RAPP with the other scales, its change over time, the inter-rater reliability, and factor structure were assessed. The subscales of RAPP correlated significantly with those of the other scales at intake and at follow-up. The RAPP scores changed significantly after treatment. Its inter-rater reliability as measured by the intra-class correlation coefficient was 0.98. The Cronbach's alpha, used to measure the internal consistency of the scale, was 0.87. The split-half reliability (Spearman-Brown) was 0.89. Principal component analysis with varimax rotation revealed six factors, which explained 67.4% of the variance. Items related to life skills explained a major proportion of the variance. The good psychometric properties, concurrent validity, high inter-rater reliability and sensitivity to change make it a useful instrument for nurses to employ to assess patients with psychoses.
