The multiphase optimization strategy (MOST) offers a framework to prepare, optimize, and evaluate behavioral interventions. This optimization trial tested 3 intervention components\u2014brief motivational interviewing (MI), storytelling videos (STVs), and oral health promotion messages (OHPMs)\u2014in enhancing mother\u2019s self-reported brushing of their preschool children\u2019s teeth. A total of 128 mothers with children &lt;5 y old were included in a 2\n                    <jats:sup>3<\/jats:sup>\n                    factorial trial. The primary outcome was children\u2019s plaque accumulation, assessed using the modified Plaque Index of Silness and L\u00f6e, with scores ranging from 0 to 3. The secondary outcome was mothers\u2019 self-reported frequency of brushing their children\u2019s teeth, categorized as at least once daily or less than once daily. Mothers were randomized to 8 experimental conditions based on combinations of on-off levels of the 3 components. Linear regression and generalized linear regression with logit link function were used to assess the impact of the components and their interactions on plaque score and daily toothbrushing after 3 mo. Multiple imputation was used for missing values. The principle of effect hierarchy guided the selection of components for inclusion in the optimized package, giving priority to main effects and 2-way over 3-way interactions. Plaque was reduced from mean = 1.8 at baseline to mean = 1.5 and daily toothbrushing increased from 50.8% to 69.5% after 3 mo. MI led to non-significantly less plaque and non-significantly more daily toothbrushing. Combining OHPMs and STVs together without MI canceled each other. Neither the main effects nor the 2- or 3-way interactions significantly affected the 2 outcomes. Individual or combined components did not significantly reduce plaque or increase daily toothbrushing. MI had the greatest promise for behavior change, and the m-oral health components need modification before they can be combined with MI in a health promotion package.\n                  <\/jats:p>","DOI":"10.1177\/00220345241291985","type":"journal-article","created":{"date-parts":[[2024,12,4]],"date-time":"2024-12-04T08:38:52Z","timestamp":1733301532000},"page":"155-163","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Optimizing mHealth Interventions for Children\u2019s Oral Hygiene: A Factorial Trial"],"prefix":"10.1177","volume":"104","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7281-7381","authenticated-orcid":false,"given":"M.","family":"Ihab","sequence":"first","affiliation":[{"name":"Department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry, Alexandria University, Alexandria University, Alexandria, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y.","family":"El-Sherif","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Alexandria University, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Yassin","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry, Alexandria University, Alexandria University, Alexandria, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Nabil","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry, Alexandria University, Alexandria University, Alexandria, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Quritum","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry, Alexandria University, Alexandria University, Alexandria, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-3258-0690","authenticated-orcid":false,"given":"N.","family":"Balbaa","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry, Alexandria University, Alexandria University, Alexandria, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4989-6584","authenticated-orcid":false,"given":"M.
