Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The proportion of judicial supervised clients that enter addiction or behavioural change treatment and stay in this treatment for at least two months. Two months is the minimal duration of the addiction and behavioural change interventions in the Netherlands. The main purpose of our intervention is to enhance problem awareness and need for treatment resulting in an increased motivation for entering treatment and treatment engagement after entry into treatment. The first is operationalized as the percentage of clients entering treatment, the second as treatment retention. Both are combined in the primary outcome measure. | — |
