DDSI

The Dual Diagnosis Screening Interview (DDSI) is a screening interview designed to detect the most common comorbid psychiatric diagnoses in substance users: Panic, Generalized Anxiety, Simple Phobias, Social Phobia, Agoraphobia, Depression, Dysthymia, Mania, Psychosis, ADHD and PTSD.

Its psychometric characteristics, together with the brevity required for its training and management, make the DDSI an adequate instrument for detecting psychiatric comorbidity in substance users in clinical practice.

Characteristics of the instrument:

- Time of administration about 15-20 minutes depending on the interviewee.

- The DDSI has shown a sensitivity and specificity around 80% for most of the evaluated diagnosis.

- It can be administered by lay interviewers after a brief training course of 90 minutes.

The Addiction Research Group (GRAd) is a multidisciplinary team of health professionals (psychiatrists, psychologists, nurses ...) The main objective of the group is to evaluate drug problems from different perspectives in order to improve both prevention and treatment. In collaboration with other groups from the IMIM-Institut Hospital del Mar d'Investigacions Mèdiques and other institutions, GRAd conducts research studies with the following main lines:

- Clinical and therapeutic aspects of addictive disorders.

- Psychiatric pathology and dual comorbidity in addictive disorders.

- New drugs.

- Drugs and gender differences.

The Epidemiology Research Group for Drug Abuse (GREDA) performs studies to determine the magnitude of the drug use problem in the general population and contributes to the study of its consequences and appropriateness of the treatments used.
