Digital Interventions for PTSD Symptoms in the General Population: a Review.

There has been a significant development of digital interventions for the treatment of Post-Traumatic Symptom Disorder (PTSD) over the past two decades. However, the majority of research has examined their clinical efficacy for military service members and veteran populations whereas community-based trauma survivors have received significantly less attention. Their effectiveness for this population, therefore, remains unclear. The aim of this review was to evaluate the effectiveness of digitally delivered psychological therapies to alleviate PTSD symptomatology in the general population. Findings showed that digitally delivered Cognitive Behavioural Therapy (iCBT) produced more consistently significant improvements in PTSD symptoms, compared to interapy, expressive writing, psychoeducation, mindfulness, cognitive tasks and psychosocial interventions. iCBT - associated improvements were also independent of the focus (i.e. trauma vs. non-trauma) of the intervention, the provision of therapeutic support (e.g. guided vs. unguided), type of feedback (e.g. automated vs. individualised) or the number of sessions provided. Nevertheless, the number of included studies for subgroup analyses was relatively low. Digital interventions have an enormous potential to improve accessibility, efficiency, clinical effectiveness and personalisation of mental health interventions. Future research is needed to investigate further the use of a wider range of therapeutic approaches across different clinical and subclinical groups and settings and test the impact of these interventions (or components) against a wider range of comparison conditions (e.g. face to face CBT) with optimal power.

Are digital interventions effective in reducing suicidal ideation and self-harm? A systematic review.

Background: There is a significant lack of outcomes research examining the effectiveness of digital interventions for reducing suicidal ideation and self-harm.Aims: To systematically review the effectiveness of digital interventions for reducing suicidal ideation and self-harm in adult populations. The possible mediating effects of depression are also discussed.Methods: The databases Pubmed, Medline, PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, IEEEXplore, ACM and CRESP were searched. Only randomised controlled trials (RCTs) were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Studies were assessed for methodological quality and risk of bias using standard assessment criteria.Results: Fourteen RCTs were reviewed, reporting data on 3455 participants. Although findings were more consistent for the effectiveness of online Cognitive Behavioural Therapy (CBT), Mindfulness-Based CBT and Dialectical Behavioural Therapy, there was insufficient research to consider any as evidence-based treatments for suicidal ideation and self-harm.Conclusions: Digital interventions for suicidal ideation and self-harm can be a safe and acceptable option for individuals unwilling or unable to access face-to-face interventions. However, further research is needed to understand the types of interventions that could support people and the risk-benefit ratio of digital interventions for these individuals.

Digitally Delivered Psychological Interventions for Anxiety Disorders: a Comprehensive Review.

Digital interventions for anxiety disorders have been well-researched over the past two decades. However, reviews to date have focused on internet-based cognitive behavioural therapy (iCBT), whereas other psychological interventions have received less attention. 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)]. 68 randomised controlled trials (RCTs) were reviewed. SAD was the anxiety disorder for which the most RCTs were conducted. Overall, findings support the effectiveness of iCBT for SAD; for the remaining interventions, although some RCTs indicated significant improvement (within groups) at post-treatment and/or follow up, between group findings were less consistent and overall, methodological differences across trials failed to provide strong supporting evidence. Finally, the level of therapist contact or expertise did not appear to affect much treatment effectiveness. Additional large, methodologically rigorous trials are needed to investigate further whether different digitally delivered psychological interventions are equally effective for anxiety disorders. Moreover, further studies are pertinent in order to examine the maintenance of therapy gains after the end of treatments and understand how these work [(e.g. the influence of therapist factors, user engagement and/or satisfaction, potential access barriers and treatments with diverse population groups (e.g. BME groups)].

Are Digitally Delivered Psychological Interventions for Depression the Way Forward? A Review.

Digitally delivered interventions aim to make psychological treatments more widely accessible and minimize clinician input. Although their clinical efficacy against wait-list, control conditions is well established, comparative outcome studies are a much better way to examine if psychotherapies are equally effective. Such reviews are still relatively lacking. The aim of this review was therefore to evaluate the effectiveness of digitally delivered psychological therapies over traditionally delivered (face-to-face) ones to alleviate symptoms in adults experiencing sub-threshold and clinical depression. Findings showed that digital interventions produced consistently clinically significant improvements in depressive symptoms. Moreover, the level of therapist contact or expertise did not affect much treatment effectiveness. Future research is pertinent to investigate further the influence of therapist input, the reasons for dropout, how to improve users' experience and therapeutic engagement and maintain improvements at post-treatment.
