Promoting adherence to psychopharmacological treatment among prisoners with mental health problems: Follow-up of a randomized controlled trial.

This study presents follow-up results regarding a treatment adherence programme (TAP) for prisoners, the initial effectiveness of which we previously evaluated in a randomized controlled trial. Here we used an experimental design with two randomized groups and assessment at four time points: baseline (pre-intervention), at 3 months (post-intervention), and at 6 and 9 months after baseline. Participants were 151 prisoners with mental health problems (Mage = 41.85, SD = 10.31) who were randomly assigned to either the TAP or treatment as usual (TAU). Prisoners who completed the TAP showed a greater improvement in treatment adherence at 3 and 9 months, compared with those who received TAU. There were no significant differences between the groups in subjective well-being under medication. The availability of an easy-to-apply, universal programme that is able to promote treatment adherence in the prison context could make a positive contribution to the general health of inmates.
