The Research

We conducted a multiple-case quasi-experimental investigation to evaluate the effects of Beat the Kick. It focused on the motivation to change substance abuse among six Dutch participants with a mild intellectual disability and borderline levels of intellectual functioning. The research team consisted of Noud Frielink PhD, Professor Carlo Schuengel PhD, Annemarie Kroon MSc, and Professor Petri Embregts PhD.



Five of the six participants (one dropped out) exhibited a change in type of motivation, from more controlled (i.e. external and introjected motivation) at baseline to more autonomous after completing the training. In other words, if a client initially wanted to change their behaviour because of external or internal rewards, penalties and expectations (controlled motivation), the training made them want to change that behaviour because the change is personally valuable or important (autonomous motivation).
