Design outcomes

Primary

MeasureTime frame
The primary outcome measure of this study is regulatory emotional self-efficacy. This construct is measured by means of the validated, 12-item Regulatory Emotional Self-efficacy (RESE) scale. The RESE scale assesses self-efficacy in managing negative emotions (8 items) and in expressing positive emotions (4 items). Negative emotional self-efficacy refers to the perceived *capability to ameliorate negative emotional states once they are aroused in response to adversity or frustrating events and to avoid being overcome by emotions such as anger, irritation, despondency, and discouragement*. Positive self-efficacy is defined as the perceived capability *to experience and to allow oneself to express positive emotions such as joy, enthusiasm and pride in response to success or pleasant events*. Earlier research has demonstrated the validity and reliability of the RESE scale. Because the RESE scale consists of only 12 items, it is easy to administer and does not require much effort of participants.

Secondary

MeasureTime frame
The secondary outcomes are treatment readiness, aggression, risk assessment and engagement. Treatment readiness and aggression are measured by the validated Dutch version of the Corrections Victoria Treatment Readiness Questionnaire (20-items) and the much-used and validated Aggression Questionnaire (12 items). In treatment of all forensic psychiatric patients, risk assessment has to be conducted by means of evidence-based risk assessment instruments. In forensic psychiatric outpatient care, the Dutch standard is the Forensisch Ambulante Risico Evaluatie (FARE), version 2. The FARE is not only used to estimate the risk on recidivism, but also to monitor changes in dynamic risk factors and risk of recidivism during treatment. Research into inter-reliability and convergent validity has shown promising results. The FARE is part of Dutch guidelines on risk assessment of forensic psychiatric outpatients. According to these guidelines, the FARE is administered twice a year, i.e. once each six months. In the FARE, 6 static and 11 dynamic risk factors are assessed. Static risk factors refer to *unchangeable* characteristics, such as age of the first offense. While they predict the risk of recidivism, they are not changeable by means of targeted interventions. Dynamic risk factors however are more related to the individual behaviour of the person and their social and living situation. Because these 11 factors are influenceable by interventions, they will be included in the analyses of this study. Finally, engagement is measured with the TWente Engagement with Ehealth and Technologies Scale (TWEETS). The scale employs a definition of engagement that incorporates behaviour, cognition, and affect, and has been shown to have a good validity and reliability. The TWEETS contains only 9 items - with three items per component of engagement - and has three slightly different versions: one for expected engagement, to be used when someone starts using an inte
