BACKGROUND: Despite growing use of computerized ambulatory monitoring in
substance dependence research, little is known about the comparative feasibility
and validity of these novel methods by substance type. This study compares the
feasibility and validity of computerized ambulatory monitoring in outpatients
seeking treatment for alcohol, tobacco, cannabis or opiate dependence.
METHODS: A total of 109 participants were recruited from an outpatient treatment
center and completed standard clinical instruments followed by 2 weeks of
computerized ambulatory monitoring of daily life experiences and substance use.
RESULTS: Individuals with cannabis dependence had the lowest rates of study
acceptance (31%) as well as compliance with the repeated electronic interviews
(79.9%), while those with tobacco dependence had the highest rates (62% and
91.0%, respectively). Concurrent validity was found between scores from standard
clinical instruments and similar constructs assessed in daily life, with no
difference by substance group. While no fatigue effects were detected, change in
some variables was observed as a function of time in the study.
CONCLUSIONS: Computerized ambulatory protocols are feasible and provide valid
data in individuals with diverse forms of dependence, but compliance to repeated
sampling methodology may vary by substance type.
