“…For example, Van der Helm, Klapwijk, Stams, and Van der Laan (2009) and Schubert et al (2012) showed that a positive or 'open' living group climate characterized by warmth and responsiveness from group workers, opportunities for development, and a safe and structured environment, had a positive effect on the treatment of juvenile delinquents. A 'closed' or repressive climate, on the other hand, has been found to be associated with negative developmental outcomes and aggression (Van der Helm, Stams, Van Genabeek, & Van der Laan, 2012). Therapeutic alliance has also been identified in the literature as a predictor of positive treatment outcomes and can be influenced (Harder, Knorth, & Kalverboer, 2012;Hurley, Lambert, Van Ryzin, Sullivan, & Stevens, 2013;Karver, Handelsman, Fields, & Bickman, 2006).…”
