Optimizing mHealth Interventions for Children's Oral Hygiene: A Factorial Trial.

Behavioral interventions can improve children's oral hygiene practices. The multiphase optimization strategy (MOST) offers a framework to prepare, optimize, and evaluate behavioral interventions. This optimization trial tested 3 intervention components-brief motivational interviewing (MI), storytelling videos (STVs), and oral health promotion messages (OHPMs)-in enhancing mother's self-reported brushing of their preschool children's teeth.

Increased perceptions of autonomy through choice fail to enhance motor skill retention.

There has been growing research interest in the effects that motivation plays in motor learning, and specifically how autonomy, competence, and social relatedness may directly benefit the learning process. Here, we present a preregistered manipulation of autonomy-support by providing learners with choice during the practice of a speed cup-stacking task. One group was given control over when a video demonstration was provided and the viewing speed.
