A Self-Rating Scale for Measuring Neuroleptic Side-Effects

Abstract
Background: A study was conducted to validate a comprehensive self-rating scale for measuring side-effects of neuroleptic drugs.Method: The Liverpool University Neuroleptic Side Effect Rating Scale (LUNSERS), which includes ‘red herring’ items, was twice administered to 50 DSM–III–R schizophrenic patients, who were also interviewed using the UKU side-effect rating scale; 50 unmedicated controls also completed the LUNSERS.Results: The test-retest reliability of the LUNSERS was good (r = 0.811, P< 0.001) as was its concurrent validity against the UKU (r = 0.828, P< 0.001). Scores correlated with chlorpromazine equivalent doses (r = 0.310, P< 0.02). ROC analysis demonstrated that the scale discriminated between patients and non-medicated controls, who scored differently for real side-effects but not for ‘red herring’ items.Conclusions: The LUNSERS is an efficient, reliable and valid method of assessing neuroleptic side-effects.
