Screening for Mental Health Problems among Patients with Substance Use Disorders: Preliminary Findings on the Validation of a Self-Assessment Instrument

Abstract: W La Revue canadienne de psychiatrie, vol 52, no 1, janvier 2007 22Objectives: We conducted a preliminary study on the validation of the Psychiatric Diagnostic Screening Questionnaire (PDSQ) among patients seeking treatment for substance use disorders (SUDs). Method:We assessed 76 patients with SUDs, using the PDSQ, followed by the Structured Clinical Interview for DSM-IV. Sensitivity, specificity, positive and negative predictive values, and receiver operating characteristic (ROC) curves were calculated.Resul… Show more

“…Moreover, the performance of the Psychiatric Diagnostic Screening Questionnaire (PDSQ) [11] was assessed among a sample of 1,000 psychiatric outpatients but only 13% of them had a SUD, mostly alcohol-use disorders. Later the PDSQ was validated in different samples of substance users with controversial results [12,13,14]. The Boston Consortium of Services for Families in Recovery (BCSFR) instrument [15] was tested only in female substance abusers and was found to be a useful screening instrument for detecting posttraumatic stress disorder (PTSD) in women beginning treatment, but not for detecting other mental illnesses.…”

“…Solo en la escala TDM se registraron diferencias de interés, con un VPN sensiblemente más elevado en nuestra muestra (95.5% frente a 86%). Esta diferencia concuerda con la registrada en dos estudios realizados con población adicta 13,14 en los que se obtuvo un VPN de 97% para esta escala, más próximo al obtenido en nuestra validación. A la vista de cuanto antecede se refrenda la elevada fiabilidad del PDSQ para evitar falsos negativos.…”

“…En nuestro caso y utilizando los puntos de corte originales, la especificidad media fue aceptable e, incluso, ligeramente más elevada que en la validación original del cuestionario (69.47% frente a 67.83%). Como advierten Castel y colaboradores 14 , el hecho de que la muestra de validación original fuera de características distintas a la población adicta a sustancias -se utilizó población clínica psiquiátrica-justificaría este tipo de diferencias. La validez predictiva de un instrumento de screening puede variar dependiendo de las características de la población en la que se aplique.…”
