Abstract

Conversational agents or chatbots are a novel, highly accessible, and low-resource method of psychological intervention delivery. The present research aims to compare two brief chatbot interventions that delivered cognitive restructuring and defusion interventions, respectively. It was hypothesized that a defusion chatbot would lead to reduced cognitive fusion and decreased thought believability relative to cognitive restructuring and a nonactive control. Participants (N = 223; M age of 28.01 [SD = 10.29]; 47 identified as male, 174 as female, and 2 as nonbinary) were randomized into one of three conditions (defusion, restructuring, control), engaged for 5 days completing thought and mood measures pre- and postintervention. Sixty-two participants (M age of 25.98; SD = 8.647 years) completed measures again at time 2 (49 identified as female, 12 as male, and 1 as nonbinary). No statistically significant differences were observed among groups on believability of thoughts (F[2, 25] = .79, p = .47, ηp2 = .06), negativity of thoughts (F[2,25] = 1.49, p = .25, η 2 = .11), discomfort associated with thoughts (F[2, 25] = .48, p = .62, ηp2 = .04), and willingness (F[2, 25] = 3.00, p = .07, ηp2 = .19) to have negative self-referential thoughts. Moreover, substantial attrition of 72% was observed. Acceptability and usability of the chatbots employed are discussed as contributing toward the limited effectiveness of interventions and elevated attrition. Various recommendations are presented to support researchers and clinicians in developing engaging and effective chatbots.

Abstract

Objective
To report the theoretical basis and design of a novel digital Acceptance and Commitment Therapy (ACT) intervention for people with chronic pain, the Pain Tracker Self Manager (PTSM), which had promising efficacy in a recent pilot trial.

Methods
Content development by a multidisciplinary panel of experts in psychiatry, clinical psychology, nursing and social work, with feedback from a group of patients with chronic pain and their providers. Materials included paper-based sketching of a story character, visual metaphors, and a series of stories designed to deliver the theory-based components of our behavioral intervention.

Results
This development and design process resulted in 4 digitally delivered clinical modules that combine visual and verbal cues. In addition, it generated a series of novel ACT metaphors specifically tailored to patients with chronic pain: Pain: Injury vs. Threat, Life Navigation System, The Fog of Pain, and Get Rhythm. Consistent with ACT theory and the contextual behavioral science framework, PTSM utilized: perspective-taking, values clarification, acceptance strategies, and nursing and psychological care recommendations.

Discussion
Reports of the design and theoretical basis of digital health interventions are highly needed to increase the rigor of their development process and more progressively advance our body of knowledge. This pilot study developed and tested a series of ACT metaphors that can be readily used by ACT clinicians working with this population.

Conclusion
PTSM is a novel digital ACT intervention for patients with chronic pain with features directly linked to ACT processes and theory.
