Methods: This study included 218 students aged 10\u201311 years who underwent a 12-week standardized parent\u2013child exercise intervention. The intervention group completed two structured parent\u2013child tasks per week through a digital platform (Ding Talk App) while maintaining regular physical education classes; the control group only maintained their regular physical education classes. Assessments were conducted using the Physical Activity Rating Scale, Exercise Attitude Scale, and mental health scales (The Spence Children\u2019s Anxiety Scale (SCAS) and The Patient Health Questionnaire-9 (PHQ-9)) at four stages: pre-intervention (T1), mid-intervention (T2), post-intervention (T3), and a 2-month follow-up period (T4). The intervention effects and effect sizes (\u03b7p2) were examined using Repeated Measures Analysis of Variance. Results: At the behavioral level, a significant group \u00d7 time interaction was found for physical activity volume (F = 17.651, p = 0.04, \u03b7p2 = 0.138), indicating the presence of a moderate effect. At the psychological level, significant interactions were observed across exercise attitude dimensions (behavioral attitude: F = 3.699, p = 0.002, \u03b7p2 = 0.033; perceived behavioral control: F = 4.189, p = 0.006, \u03b7p2 = 0.037; subjective norm: F = 4.616, p &lt; 0.001, \u03b7p2 = 0.040) and mental health measures (depression: F = 4.009, p = 0.026, \u03b7p2 = 0.044; anxiety: F = 3.1, p = 0.016, \u03b7p2 = 0.020), though no significant effect was found for behavioral intention (F = 1.346, p = 0.259, \u03b7p2 = 0.012), with all significant effects being relatively weak. Conclusions: The home\u2013school collaborative, digital platform-based parent\u2013child exercise intervention demonstrated positive effects on children\u2019s physical activity volume, exercise attitudes, and mental health, offering a feasible and promising strategy to support more integrated child health promotion initiatives.<\/jats:p>","DOI":"10.3390\/bs16020282","type":"journal-article","created":{"date-parts":[[2026,2,16]],"date-time":"2026-02-16T12:37:28Z","timestamp":1771245448000},"page":"282","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Digital Parent\u2013Child Intervention on Children\u2019s Exercise Behavior and Psychological Development\u2014A Randomized Controlled Trial Based on Family Perspective"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9855-8365","authenticated-orcid":false,"given":"Yijuan","family":"Lu","sequence":"first","affiliation":[{"name":"School of Physical Education, Hangzhou Normal University, Hangzhou 311121, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengsheng","family":"Li","sequence":"additional","affiliation":[{"name":"School of Physical Education, Hangzhou Normal University, Hangzhou 311121, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Physical Education, Hangzhou Normal University, Hangzhou 311121, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feijun","family":"Meng","sequence":"additional","affiliation":[{"name":"Hangzhou Dongrun Foreign Language School, Hangzhou 311215, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Feng","sequence":"additional","affiliation":[{"name":"School of Physical Education, Hangzhou Normal University, Hangzhou 311121, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yijia","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Physical Education, Hangzhou Normal University, Hangzhou 311121, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wu","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Physical Education, Hangzhou Normal University, Hangzhou 311121, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Physical Education, Hangzhou Normal University, Hangzhou 311121, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1016\/0749-5978(91)90020-T","article-title":"The theory of planned behavior","volume":"50","author":"Ajzen","year":"1991","journal-title":"Organizational Behavior and Human Decision Processes"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"90","DOI":"10.1186\/s12966-025-01778-9","article-title":"Parents\u2019 experiences of family-based physical activity interventions: A systematic review and qualitative evidence synthesis","volume":"22","author":"Brennan","year":"2025","journal-title":"International Journal of Behavioral Nutrition and Physical Activity"},{"key":"ref_3","first-page":"894","article-title":"Early Parent-child interaction and children\u2019s social development: Application evidence based on an interactive behavior coding scheme","volume":"40","author":"Bu","year":"2024","journal-title":"Psychological Development and Education"},{"key":"ref_4","unstructured":"Cohen, J.
