Digital-Based Interventions for Complex Post-Traumatic Stress Disorder: A Systematic Literature Review

Research has shown that complex post-traumatic stress disorder (cPTSD) differs from post-traumatic stress disorder (PTSD) on core symptoms relating to the individual's sense of self, and this has driven the need for treatment approaches to address these specific features of cPTSD. The COVID-19 pandemic has led to the increased use of digital-based interventions (DBIs) to treat mental illnesses, including trauma-related disorders. However, while evidence for the use of DBIs for PTSD has previously been synthesized, the current review is the first synthesis of research on the use of DBIs for cPTSD. A systematic search of Scopus, PsychINFO, and EBSCOhost was conducted, using search terms targeting "cPTSD" and "DBIs," to identify research on the use of DBIs to treat cPTSD symptoms. Ten papers were identified, which provided preliminary evidence for the efficacy of DBIs to reduce cPTSD symptoms. Further, DBIs were reported as acceptable by individuals with a history of complex trauma. The paper also provides insight into the therapeutic approaches adopted, digital modalities utilized, safety measures included, and whether/to what degree support was provided. While DBIs show promise for treating cPTSD, there is substantial room for advancement of the empirical evidence base for these approaches. Both clinical and research-based recommendations are provided separately.

Review of the current empirical literature on using videoconferencing to deliver individual psychotherapies to adults with mental health problems

PURPOSE

The COVID-19 pandemic has resulted in a widespread adoption of videoconferencing as a communication medium in mental health service delivery. This review considers the empirical literature to date on using videoconferencing to deliver psychological therapy to adults presenting with mental health problems.

METHOD

Papers were identified via search of relevant databases. Quantitative and qualitative data were extracted and synthesized on uptake, feasibility, outcomes, and participant and therapist experiences.

RESULTS

Videoconferencing has an established evidence base in the delivery of cognitive behavioural therapies for post-traumatic stress disorder and depression, with prolonged exposure, cognitive processing therapy, and behavioural activation non-inferior to in-person delivery. There are large trials reporting efficacy for health anxiety and bulimia nervosa compared with treatment-as-usual. Initial studies show applicability of cognitive behavioural therapies for other anxiety and eating disorders and obsessive-compulsive spectrum disorders, but there has yet to be study of use in severe and complex mental health problems. Therapists may find it more difficult to judge non-verbal behaviour, and there may be initial discomfort while adapting to videoconferencing, but client ratings of the therapeutic alliance are similar to in-person therapy, and videoconferencing may have advantages such as being less confronting. There may be useful opportunities for videoconferencing in embedding therapy delivery within the client's own environment.

CONCLUSIONS

Videoconferencing is an accessible and effective modality for therapy delivery. Future research needs to extend beyond testing whether videoconferencing can replicate in-person therapy delivery to consider unique therapeutic affordances of the videoconferencing modality.

PRACTITIONER POINTS

Videoconferencing is an efficacious means of delivering behavioural and cognitive therapies to adults with mental health problems. Trial evidence has established it is no less efficacious than in-person therapy for prolonged exposure, cognitive processing therapy, and behavioural activation. While therapists report nonverbal feedback being harder to judge, and clients can take time to adapt to videoconferencing, clients rate the therapeutic alliance and satisfaction similarly to therapy in-person. Videoconferencing provides opportunities to integrate therapeutic exercises within the person's day-to-day environment.
