Evidence demonstrated that CBT with a trauma focus (CBT-TF) was associated with the largest evidence of effect when compared to waitlist/usual care in reducing PTSD symptoms post treatment (10 studies; n = 524; SMD -1.22, -1.78 to -0.66).
While the review found some beneficial effects of i-CBT for PTSD post-treatment, the quality of the evidence was very low because of the small number of included trials and there was insufficient evidence to support the maintenance of improvement at follow-up of 3-6 months.
The aim of this review was therefore to evaluate the effectiveness of digitally delivered psychological therapies (CBT, Attention Bias Modification, Exposure Therapy, Applied Relaxation, Bibliotherapy, Psychodynamic Therapy, Mindfulness, Behavioural Stress Management, Counselling) compared with control conditions and/or other psychological interventions for anxiety disorders (Social Anxiety Disorder (SAD), Health Anxiety, Obsessive-Compulsive Disorder (OCD), Post-traumatic Stress Disorder (PTSD), Specific Phobias, Panic Disorder (PD), Generalised Anxiety Disorder (GAD)].
However, given the different theoretical and methodological substrate of TF-CBT and EMDR, a potentially different impact on the brain for the two interventions could be hypothesized, as well as an interaction between trauma-specific PTSD symptomatology and response to a given psychotherapy.
The treatments were standard CBT protocols for post-traumatic stress disorder (PTSD), complicated grief (CG), or adjustment disorders (ADs), depending on each patient diagnosis.
Results from trials of TF-CBT are limited and inconclusive regarding its effectiveness on PTSD, or on psychotic symptoms or other symptoms of psychological distress.
This study aimed to investigate the efficacy and feasibility of an Internet-based, therapist-guided cognitive-behavioral therapy (Internet-based CBT) for older individuals with PTSD symptoms.
