Acceptability and Outcomes of Transdiagnostic Guided Self-help Bibliotherapy for Internalizing Disorder Symptoms in Adults: A Fully Remote Nationwide Open Trial

Abstract

Introduction Doing What Matters in Times of Stress (DWM) is a five-module transdiagnostic guided self-help (GSH) intervention developed by the World Health Organization, originally in a group-based format. In a sample of individuals recruited from across the United States, we conducted an open trial to study the feasibility and acceptability of an adaptation of DWM in which guidance was provided individually and remotely via phone and videoconferencing. Methods We assessed internalizing symptoms, psychological well-being, work and social functioning, usability of the intervention, and emotion regulation over the course of 6 weeks. Results A total of 263 individuals completed our screening. Of those, 75.29% ( n = 198) qualified for the intervention. We reached most participants who qualified (71.21%, n = 141) via phone to schedule a GSH session. Most of those scheduled attended a study session (84.4%, n = 119), and most of those who attended a session completed more than half the treatment (84.03%, n = 100). Retention rates were comparable to meta-analytic estimates of dropout rates in GSH. Participants showed improvement on internalizing symptoms, psychological well-being, work and social functioning, usability of the intervention, and emotion regulation. Conclusion DWM is a freely available, seemingly efficacious transdiagnostic intervention for internalizing disorder symptoms.

Wider, faster, more: Reenvisioning depression treatment research in the United States.

“…These early gains are not a placebo response and instead appear more characteristic of active treatments than placebos (Zilcha-Mano et al, 2017) and tend to be sustained (Shalom & Aderka, 2020). The early treatment period is also critical for determining treatment engagement, as high dropout rates are observed before treatment begins and early in treatment (Krendl & Lorenzo-Luaces, 2022; Lorenzo-Luaces et al, 2023). Therefore, in a sequential treatment program, each step should have a relatively short duration, and treatment should commence promptly.…”

“…LITs may nonetheless appeal to individuals who desire to self-manage symptoms. As with higher intensity treatments, response and engagement with LITs are evident relatively quickly (Lorenzo-Luaces et al, 2023).…”

A qualitative feasibility and acceptability study of an acceptance and commitment-based bibliotherapy intervention for people with cancer

“…One such intervention type is bibliotherapy, or the therapeutic use of books and other reading materials (Bilich et al, 2008; Howie, 1988) which can be used to address psychological and physical health concerns (Hedman et al, 2016). Among them, bibliotherapy has been used to provide support for internalizing type problems, such as depression and anxiety (Lorenzo-Luaces et al, 2023), and managing a number of long-term conditions including: chronic pain (Thorsell et al, 2011; Veillette et al, 2019), appearance related concern (Muftin and Thompson, 2013; Powell et al, 2023), distress associated with multiple sclerosis (Proctor et al, 2018) and in post-stroke management (Gladwyn-Khan and Morris, 2023).…”
