First, to describe a combined qualitative and quantitative method for describing and measuring past treatment
of Substance Use Disorder (SUD). Second, to use this method in assessing whether lifetime treatment
is related to age, duration of substance use, or severity of SUD.
Retrospective descriptive data with blinded assessments.
Alcohol-Drug Programs located within university departments of psychiatry in 2 centers.
Six hundred forty-two patients with SUD.
Data collection instruments included:
- Questionnaire regarding lifetime use of 7 SUD treatment care settings, lifetime number of admissions, lifetime days in treatment, and attributed cost of treatment;
- Age and duration of substance use;
- Lifetime SUD severity as assessed by self-rated SUD instrument (MAST/AD), interview-based questionnaire regarding previous SUD treatment (M-SAPS), attempts at self-help (scale of 0 to 7 self-help methods), and addiction psychiatrist-rated global score of psychosocial functioning (GAF).
modality, admissions, days in treatment
, and cost
all correlated highly with each other but at various levels from moderate to strong correlations. Severity of SUD, rather than age or duration of substance use, predicted the treatment
outcomes most strongly. This was true whether treatment
severity was assessed by the patient or by an interviewer using a scheduled interview instrument. Global psychosocial impairment over the previous year was also associated with 3 out of 4 treatment
This method of assessing lifetime SUD treatment
is feasible and shows strong reliability with self-rated SUD severity and validity with interviewer and psychiatrist ratings. Severity of SUD is correlated with lifetime types and quantity of treatment
