In this first effectiveness study of psychotherapeutic counseling for students in German-speaking countries, the effectiveness of an integrative model of counseling was evaluated based on a sample of 151 clients. Effectiveness of integrative counseling according to the ABCDE-model was found to be high in comparison to other international studies in this area. Pre-post differences on measures of mental distress and satisfaction were significant and effect sizes were mostly moderate to high. A high percentage of clients improved statistically and clinically significant. Counselors' expert rating and diagnostics according to ICD-10 that have been included in contrast to previous effectiveness studies showed that clients suitable for the counseling setting get treated in the counseling center while more severely disturbed clients in terms of psychopathology or diagnosis get referred to outpatient treatment, drop out or object to provide post-data.
