Résumé
"The Schizophrenia Objective Functioning Instrument (SOFI) is an intervieweradministeredscale designed to objectively assess the actual level of patient functioning and tomeasure community functioning related to cognitive impairment and psychopathology. The aimwas to examine the psychometric properties of the Spanish version of the SOFI (Sp-SOFI) in asample of 155 Spanish outpatients with schizophrenia disorder. The instruments applied were Sp-SOFI, Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression-SchizophreniaScale (CGI-SCH), Personal and Social Performance Scale (PSP), and Global Assessment of Functioning(GAF). The discrimination indexes of the Sp-SOFI items range from .21 to .77. Exploratoryfactor analysis showed an essentially one-dimensional structure. Cronbach’s alpha was .93.Test-retest reliability for the Sp-SOFI total score was .87 (p < .001). The canonical correlationbetween SP-SOFI domains and PSP dimensions was .83. The multiple correlation coefficientbetween Sp-SOFI domains and GAF score was .84. Sp-SOFI scores were significantly differentbetween high and low scores on the PANSS scales (p < .001). Sp-SOFI measures discriminatedamong patients with doubtful, mild, moderate, and severe schizophrenia disorder accordingto CGI-SCH scales (p < .001). New evidence about the validity of the SOFI was provided. TheSp-SOFI is a reliable and valid tool for using in clinical practice."
