Consistencia interna del cuestionario autoadministrado de la Entrevista Clínica Estructurada para Trastornos del Eje II del DSM-IV*

introduction: it is infrequent to identify possible personality disorder cases among the general population due to the lack of self-applied instruments with good validity and reliability. up to this time, what has not been explored is the reliability of the self-report questionnaire of the scid-ii in any community or clinical population. objective: to determine the internal consistency of the twelve sub-scales of the self-rated questionnaire of the scid-ii in adults from the general population of bucaramanga, colombia. method: a probabilistic sample of 2,496 adults dwelling in the urban area of bucaramanga, colombia, completed the self-administered questionnaire of the scid-ii. the mean age of the group was 38.0 years; and the mean formal scholarship was 9.2 years. the self-reporting questionnaire of the scid-ii has 119 questions that investigate the twelve personality disorders defined by the dsm-iv. to know the internal consistency for each sub-scale the kuder-richardson？s formula-20 was computed. results: the kuder-richardson coefficient was 0.75 for antisocial personality disorder; 0.70, for avoidant; 0.54, for borderline; 0.55, for dependent; 0.61, for depressive; 0.59, for histrionic; 0.72, for narcissistic; 0.68, for obsessive-compulsive; 0.73, for paranoid; 0.63, for passive-aggressive; 0.69, for schizoid; and 0.72 for schizotypal. conclusions: the internal consistency varies significantly for each sub-scale of self-reported questionnaire of the scid-ii, and it is sufficiently high for five out of twelve sub-scales: avoidant, antisocial, histrionic, paranoid, and schizotypal personality disorders. it is necessary to investigate further, and to corroborate these findings in other settings and popopulations.
