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.
