Abstract: Recent research efforts have focused on assessing the therapeutic community
(TC) treatment process. The current article examines the validity of the client self-report
Dimensions of Change Instrument (DCI) treatment process measure, by confirming its
factor structure and examining each subscale’s relationship with time in treatment, scales
from an existing process assessment, and mental and physical health status. Participants
were 511 adult and adolescent residential TC clients. The factor structure of the DCI
replicated with satisfactory fit. The pattern of associations between DCI subscales and
criterion measures was largely as expected, providing initial concurrent and discriminant
validity evidence for the DCI.
Keywords: Health, post-treatment outcomes, therapeutic community, treatment
process.
