Chapter 3 74 One item (item 24) of the Addiction Severity Index (ASI (34, 35)) will be used to measure the extent to which respondents have been bothered in the past 30 days by problems with a.) alcohol, or b.) drugs. Illness outcomes: symptoms and relapses The secondary outcomes on illness-management outcomes are symptoms, health complaints & functional limitations, and relapses. These topics will be measured with the following: The Brief Symptom Inventory (BSI (36–38)), 53 items.

The EQ-5D (39), five items. This scale measures primarily health complaints (in a broad sense) and functional limitations. The EQ-5D is the Euro-QOL self-report scale and has good psychometric properties. The number of relapses will be operationalized as the number and duration of hospital admissions and number of emergency-department visits.

Mueser divides subjective recovery into perceived recovery, sense of purpose and personal agency, and divides objective recovery into social and role functioning. As secondary outcome measures we will use five scales to assess subjective recovery and one longer scale for objective recovery.
