38 Conclusion The present study is the first study that examined psychometric properties of the GCI adapted to measure perceived living group climate in individuals with MID-BIF and severe behavioural problems. The GCI could be used to monitor the living group climate in secure, forensic facilities for individuals with MID-BIF on a regular basis. That contributes to our understanding of how the living group climate can be improved for the benefit of both sociotherapists and clients with MID-BIF in secure settings. The current findings are found not only in secure res- idential care for children, adolescents and adults without MID-BIF (Heynen et al., 2014; Strijbosch et al, 2014; Van der Helm, 2011) but also in residential care and treatment for adults with MID-BIF. These outcomes also brings us a step closer to a standardised instrument that can be used to measure living group climate in different kinds of settings and in a broader range of target groups and to evaluate the effectiveness of interventions that aim to improve living group climate.
