Systemic Psychotherapy: An Introduction to Its Theoretical Foundations and Clinical Practice.
Systemic therapy (ST) was approved as a further psychotherapy approach in line with the German Psychotherapy Directive's requirements in 2020 for adults and in 2024 for children and adolescents, and is thus covered by statutory health insurance. ⋯ ST broadens the scope of treatment options for mental disorders, with a specific focus on their social context.

The gold standard for evaluating interventions in medicine and health care is the randomized controlled trial (RCT). In practice, however, RCTs may be difficult to conduct because of high costs, ethical aspects, or practical considerations. This is particularly true of studies on the population level, e.g., for the evaluation of health policy measures. ⋯ As long as all sources of bias have been avoided and the findings are both plausible and robust, the effects revealed by ITS can be interpreted as causal. ITS may serve as an alternative method for evaluating intervention effects when an RCT cannot be performed.
