The two follow-back calendars (Drug/Alcohol and Residential) are forms for assessing client patterns using the Time-Line Follow-Back (TLFB) method (Sobell et al., 1980). The Drug/Alcohol TLFB Calendar assesses a person's pattern of substance use over the past six months, including specific amounts of different types of substances reported for each month. The Residential TLFB Calendar assesses a person's pattern of residences, moves, hospital/prison stays, and homelessness for up to 12 months. In addition to the calendar form, there are additional pages where more details are obtained once the basic information is captured on the calendar.
More information regarding the Drug/Alcohol TLFB Calendar, and the clinician rating scales developed by the PRC, is available in:
