title: Treating Depression and Anxiety with Digital Cognitive Behavioural Therapy for Insomnia: A Real World NHS Evaluation Using Standardized Outcome Measures.
abstract: BACKGROUND
  Evidence suggests that insomnia may be an important therapeutic target to improve mental health.
  
  
  OBJECTIVE
  Evaluating changes in symptoms of depression and anxiety after supported digital cognitive behavioural therapy (dCBT) for insomnia delivered via a community-based provider (Self Help Manchester) of the Improving Access to Psychological Therapies (IAPT) service.
  
  
  METHODS
  Supported dCBT for insomnia was delivered to 98 clients (mean age 44.9 years, SD 15.2, 66% female) of Self Help Manchester. All clients received six support calls from an eTherapy coordinator to support the self-help dCBT. During these calls levels of depression (Patient Health Questionnaire, PHQ-9) and anxiety (Generalized Anxiety Disorder, GAD-7) were determined.
  
  
  RESULTS
  Depression (M difference-5.7, t(70) = 12.5, p < .001) and anxiety [Generalized Anxiety Disorder-7 (GAD-7), M difference-4.1, t(70) = 8.0, p < .001] were reduced following supported dCBT for insomnia. This translated into an IAPT recovery rate of 68% for depression and anxiety.
  
  
  CONCLUSIONS
  These results suggest that dCBT for insomnia alleviates depression and anxiety in clients presenting with mental health complaints in routine healthcare.
