VRainSUD: Content validation of a Cognitive Training Program using the Delphi Method

Abstract

Abstract Substance abuse has undeniable effects on a number of cognitive dimensions, namely memory and executive functioning. In turn, deficits in these dimensions have been associated with poorer treatment outcomes for Substance Use Disorders (SUD). The main goal of this study was to validate VRainSUD, a cognitive training program composed of a virtual reality platform and a mobile follow-up application that proposes to reduce cognitive deficits in individuals with SUD. The Delphi method was used to reach a consensus on each of the program’s characteristics (e.g., structure, cognitive training tasks). A panel of experts was invited to participate in the content validation by answering two rounds of questions (scale and free-text boxes) regarding the program. Changes were made between the rounds according to the results of the first round. The consensus was defined as at least 70% of the experts agreeing on the validity of a characteristic. From 39 invited experts, 11 completed the first round, and 6 completed both rounds. The structure of the program reached a consensus on the first round, along with most tasks (with the exception of two mobile application tasks). Significant changes were made following the feedback received, namely turning the program personalizable, and adding positive feedback to the tasks in order to improve adherence and engagement. The Delphi method was a valuable tool to improve VRainSUD. The experts’ opinions not only allowed for the validation of main features, but also informed important additional changes.
