Abstract

Group cognitive behavioural therapy (gCBT) is commonly used in Increasing Access to Psychological Therapies (IAPT) services. However, there is limited knowledge of the efficacy of gCBT as a delivery format for generalised anxiety disorder (GAD). To address gaps in literature, this study aims to explore the efficacy and attrition of individual and group CBT interventions, respectively, at Step 3 for GAD using data from a routine IAPT service over a 24-month period. Data were retrospectively derived from a routine serviceʼs IAPTus database, separating those eligible for comparison into group (n = 44) and individual (n = 55) CBT for GAD. Outcomes were differences in pre–post self-reported anxiety (GAD-7) and depression (PHQ-9) scores, clinical recovery and attrition for gCBT and individual CBT. Both gCBT and individual CBT yielded significant reductions in self-reported anxiety and depression scores over time. Results indicate that 53% of patients attending individual CBT achieved clinical recovery, with similar but less competitive rates of 41% in gCBT. Attrition rates were similar between gCBT (29.5%) and individual CBT (27.3%), respectively. Preliminary results suggest that both individual and gCBT are effective interventions for GAD patients in IAPT, offering symptom alleviation and comparable recovery and attrition rates post-intervention. This observational design offers credibility and insight into a pragmatic evaluative and explorative comparison. gCBT may offer an acceptable and potentially economical alternative.

Key learning aims

  1. (1) To explore whether gCBT and individual CBT yield significant symptom reduction in self-reported anxiety and depression in GAD patients from a routine IAPT service.

  2. (2) To explore gCBT and individual CBT clinical recovery rates in non-optimum routine conditions.

  3. (3) To explore whether gCBT for GAD produces unacceptable attrition rates and if this differs from attrition rates in individual CBT for GAD in a routine IAPT service.
