ABSTRACT
Activity monitoring has a long history as a behavior therapy assessment tool, but research suggests that it may be important to outcome on its own (Heidt & Marx, 2003). It is incorporated in both BA and BATD. We recommend that an initial activity monitoring assignment is given in Session 1, to begin obtaining detailed information about the frequency and patterns of speci®c client behaviors and the breadth or restriction of activity in general over time. The clinician and client should collaboratively determine the speci®c format of activity monitoring that will work best for the client. This can be the traditional activity chart (a simple day/time grid), a calendar or day planner, or a diary or journal (i.e., each night the client journals about his or her day), as long as it provides the clinician with the necessary information. In general, the client is asked to monitor activity and record it repeatedly over the course of the week, to get the most accurate record possible, but often clients will complete it nightly or just before the session, retrospectively. Any information collected is to be regarded as helpful by the therapist.
