Impact of Computer-Mediated Versus Face-to-Face Motivational-Type Interviews on Participants’ Language and Subsequent Cannabis Use: Randomized Controlled Trial

Impact of Computer-Mediated Versus Face-to-Face Motivational-Type Interviews on Participants’ Language and Subsequent Cannabis Use: Randomized Controlled Trial

A meta-analysis of 119 MI efficacy studies yielded a small but significant effect of MI compared with alternative interventions (d=0.22) [1]. More than 40 studies have investigated the feasibility of conducting motivational interviews delivered partially or completely via computers, mobile phones, robots, voice-activated recordings, and related platforms [4,5]. Many of these studies have used text-based motivational interviews that rely on written interactions between the interviewer and interviewee.

Consumer-Grade Neurofeedback With Mindfulness Meditation: Meta-Analysis

Consumer-Grade Neurofeedback With Mindfulness Meditation: Meta-Analysis

For between-participant designs, we primarily calculated Becker’s del for effect sizes, which is the Cohen d for the mb NF group minus the Cohen d for the control group [93]. This provides a simple measure of the degree of differential change between the groups. In cases of incomplete reporting, we converted t tests or partial eta-squared to Cohen d. All effect sizes were converted using Hedges g correction, as many sample sizes were small.
