Conditions

psychotic disorders and schizophrenia spectrum disorders

Interventions

To address these specific risk factors we developed a psychomotor assertiveness training with elements of kickboxing. The intervention consists of 20-sessions of group training divided into five mod

Design outcomes

Primary

Measure	Time frame
We hypothesise that the assertiveness intervention is applicable and its effects can be measured in a RCT using the chosen outcome measures, and that the chosen set up will lead to a sufficient number of participants. We constructed three goals to investigate this hypotheses. First of all we want to evaluate and improve intervention protocols. Trainers, participants, and involved psychiatric workers are asked for feedback and asked about wanted and unwanted effect of the sessions. After the intervention participants fill in an qualitative questionnaire about the subjective experience of the training. We expect that 80% of the participants indicate on this questionnaire that the intervention was helpful or very helpful. We also expect that the trainers and involved psychiatric workers have a positive opinion on the interventions protocol. Second, we want to explore parameters that are needed for the RCT. The feasibility study will tell us more about the willingness of therapist to refer clients to the intervention and the willingness of clients to participate. The coordinating researcher will monitor intervention adherence, drop-outs, and keep track of the time schedules and intervention procedures. We expect to find 24 patients willing to participate and drop-out rate will not be higher than 20%. Third, we want to explore suitable outcome measures to estimate sample size and power calculation for the RCT. We will use a theory-based selection of the instruments stated in Table 2. We expect that the effect sizes of these instruments are small to moderate.	—
