Chilean validation of the operationalized psychodynamic diagnosis-structure questionnaire (OPD-SQ) for personality structure

BACKGROUND: This is the validation of the Operationalized Psychodynamic Diagnosis—Structure Questionnaire (OPD-SQ). METHODS: A clinical sample of 399 adults and a nonclinical general population sample of 50 healthy adults completed measures of depression, attachment, psychiatric symptomatology and distress. Internal consistency and concurrent validity were assessed. Test–retest and Reliable Change Index were also calculated, as was the ability of the OPD-SQ to distinguish between the clinical and general population groups. RESULTS: High internal consistencies were found; significant differences between clinical and nonclinical samples, and significant associations with psychiatric symptomatology, depression and psychological distress. CONCLUSION: The Chilean OPD-SQ has good reliability, and discriminates between clinical and healthy samples.
