Análise das características psicométricas do inventário de sintomas SCL-90-R através do Modelo de Rasch

Abstract

The objective of present investigation was to perform an analysis of the psychometric characteristics of the SCL-90-R symptom inventory using the Rasch Model, in a sample of individuals with substance use disorder inserted in the therapeutic community, as an instrument for assessing possible emotional impairments in neuropsychological disorders present in these individuals. The sample consisted of 315 subjects, 90.2% male, aged between 20 and 73 years. The results observed allow us to verify that all Linacre guidelines (2002) are successfully overcome and that the main reliability indicators point to very adequate results, both for items and for people, suggesting an appropriate instrument, with good psychometric characteristics, useful and effective in evaluating the presence of psychopathological symptoms. Given the repercussion of emotional states on cognitive functions, the SCL-90-R as an instrument for assessing emotional changes can be of great use in neuropsychological evaluation.
