Preferences for Mobile App Features to Support People Living With Chronic Heart Diseases: Discrete Choice Study

Preferences for Mobile App Features to Support People Living With Chronic Heart Diseases: Discrete Choice Study

We chose a D-optimal design over an orthogonal design for its capacity to produce accurate parameter estimates with a smaller sample size [25]. One important consideration in D-optimal design is specifying the number of choice tasks or the design size [26]. According to the formula “number of attribute levels/(number of alternatives-1),” a minimum design size of 6 per block was required [27]. While larger design sizes typically improve statistical efficiency, they can compromise response efficiency [23].

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.
