Psychometric properties of a Spanish-version of the Schizophrenia Objective Functioning Instrument (Sp-SOFI)
The Schizophrenia Objective Functioning Instrument (SOFI) is an interviewer-administered scale designed to objectively assess the actual level of patient functioning and to measure community functioning related to cognitive impairment and psychopathology. The aim was to examine the psychometric prop...

The multiple correlation coefficient between Sp-SOFI domains and GAF score was .84. Sp-SOFI scores were significantly different between high and low scores on the PANSS scales (p<.001).

El objetivo del estudio consistió en examinar las propiedades psicométricas de la versión española de la SOFI (Sp-SOFI) en una muestra de 155 pacientes ambulatorios con esquizofrenia. Los índices de discriminación de la Sp-SOFI oscilaron entre 0,21 y 0,77. El análisis factorial exploratorio mostró una estructura esencialmente unidimensional. El alfa de Cronbach fue 0,93. El coeficiente de fiabilidad test-retest fue 0,87 (p<0,001). La correlación canónica entre la Sp-SOFI y la Escala de Funcionamiento Personal y Social (PSP) fue 0,83. El coeficiente de correlación múltiple entre la Sp-SOFI y la Escala de Evaluación de la Actividad Global (EEAG) fue 0,44. Las puntuaciones en la Sp-SOFI fueron significativamente diferentes entre los pacientes con puntuaciones altas y bajas en la Escala del Síndrome Positivo y Negativo (PANSS) (p<0,001).
