Validation of the Luria-Nebraska Intellectual Processes Scale as a measure of intelligence in male alcoholics.
This study investigated the Luria-Nebraska Intellectual Processes Scale (IPS) as a predictor of Wechsler Adult Intelligence Scale (WAIS) IQs among alcoholic inpatients. Strong correlations were found between the IPS and WAIS Verbal IQ and Full Scale IQ; however, the correlation with Performance IQ was only -.41. IQ estimates based on Prifitera and Ryan's (1981) regression equations derived on psychiatric inpatients differed significantly from obtained IQs in the current alcoholic sample. The importance of adequately assessing Performance IQ among patients with alcohol-related problems is discussed.
