It is important to demonstrate replicable evidence of the effectiveness of counselling procedures. The study aimed to contribute to the currently limited evidence base examining the effectiveness of university student counselling in the UK. Information on therapeutic outcome based on Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) scores for 305 individuals attending a large UK university counselling service was analysed. Following counselling intervention: there was a statistically significant improvement in CORE-OM scores with 63% of individuals showing a reliable improvement and only 2% showing a reliable deterioration. Of those who began with a score in the clinical range, 49% showed a clinically significant change. These results provide additional evidence for the effectiveness of university counselling interventions. Future research should aim to build on this preliminary research using randomised controlled trial designs.
