A new instrument to assess participant motivation for involvement in preventive interventions.

The Nijmegen Motivation List for Prevention (NML-P) is a new instrument to assess the motivation of participants for involvement in preventive group interventions. The aim of the current study was to explore the underlying dimensions of the NML-P and the predictive potential of the instrument for those participating in a psychoeducational preventive group intervention for depression: the Coping with Depression course. Principal component analyses revealed four components: readiness to participate, social support, doubt, and burden. Preliminary prediction analyses showed doubt, support, and burden to be related to the outcome of the depression prevention intervention.
