62 To create a therapeutic group climate and stimulate clients to develop, sociotherapists should be responsive to fulfil basic psychological needs of the clients, such as the need for autonomy, competence, and relatedness (Ryan & Deci, 2017). Giving clients the op- portunity to make decisions themselves in their daily care may help to restore some feelings of control over their own lives (Blair & Kennedy, 2014). Providing opportunities to choose for themselves has been suggested to be an important component of interven- tions that aim to reduce the aggressive behaviour of clients with ID (Knotter et al., 2013). Another implication for secure forensic settings for individuals with MID-BIF relates to the continuing need of improving sociotherapists’ expertise and competences. It is important that sociotherapists are educated in psychological and psychiatric problems underlying aggressive behaviour. There is a continuing need of improving sociotherapists’ expertise and competences At last, further research is necessary in order to understand how work or team climate affect the quality of the group climate. There is preliminary evidence to suggest that a positive work climate, as perceived by sociotherapists, seems necessary in the degree to which sociotherapists can build an open and therapeutic group climate (Van der Helm & Stams, 2012). Establishing a more open and therapeutic group climate may not only result in a decrease of aggressive incidents, but also in a safer work climate for professionals.
