Social emotional learning (SEL) can be key to adolescent development and well-being. This study aimed to evaluate the ripple effects and preliminary effectiveness of EmpowerHER, an integrated PA and SEL pilot intervention, on changes in adolescent girls\u2019 PA levels and friendship networks during an 8-week summer care program. Adolescents (\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    =47, ages 10\u201314 years) wore accelerometers to measure PA and completed surveys on psychological distress, social connectedness, and friendship nominations at the start and end of summer. EmpowerHER consisted of biweekly 90-min PA and SEL skill-building sessions over 4 weeks for 11 girls within this larger sample. Stochastic actor-oriented modeling (SIENA) analyzed selection and influence processes related to changes in PA engagement and socioemotional well-being. Girls participating in EmpowerHER significantly increased their PA levels (\n                    <jats:italic toggle=\"yes\">b<\/jats:italic>\n                    = 1.57,\n                    <jats:italic toggle=\"yes\">SE<\/jats:italic>\n                    = 0.73) and were more likely to send new friendship connections over time (\n                    <jats:italic toggle=\"yes\">b<\/jats:italic>\n                    = 1.71,\n                    <jats:italic toggle=\"yes\">SE<\/jats:italic>\n                    = 0.73). Higher social connectedness was associated with elevated PA (\n                    <jats:italic toggle=\"yes\">b<\/jats:italic>\n                    = 0.31,\n                    <jats:italic toggle=\"yes\">SE<\/jats:italic>\n                    = 0.12) and increased friendship connections (\n                    <jats:italic toggle=\"yes\">b<\/jats:italic>\n                    = 0.39,\n                    <jats:italic toggle=\"yes\">SE<\/jats:italic>\n                    = 0.18) across summer. The overall sample showed significant increases in daily MVPA (mean difference 9.04 min\/day,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = .03) and friendship connections (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; .001) from start to end of summer. This exploratory study demonstrated preliminary efficacy of an integrated PA and SEL curriculum implemented through a summer care program. Participation bolstered objective PA levels and improved positive peer dynamics. The findings highlight the potential of holistic interventions addressing multiple aspects of adolescent health and development simultaneously.\n                  <\/jats:p>","DOI":"10.1177\/15248399251347892","type":"journal-article","created":{"date-parts":[[2025,6,17]],"date-time":"2025-06-17T00:56:29Z","timestamp":1750121789000},"page":"247-258","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Promoting Physical Activity and Peer Relationships in Adolescent Girls Through a Summer Program"],"prefix":"10.1177","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7886-4456","authenticated-orcid":false,"given":"Tyler","family":"Prochnow","sequence":"first","affiliation":[{"name":"Texas A&amp;M University, College Station, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan S.","family":"Patterson","sequence":"additional","affiliation":[{"name":"Texas A&amp;M University, College Station, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3099-3720","authenticated-orcid":false,"given":"Sara A.","family":"Flores","sequence":"additional","affiliation":[{"name":"Texas A&amp;M University, College Station, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1323-0254","authenticated-orcid":false,"given":"Jeong-Hui","family":"Park","sequence":"additional","affiliation":[{"name":"Texas A&amp;M University, College Station, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurel","family":"Curran","sequence":"additional","affiliation":[{"name":"Texas A&amp;M University, College Station, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily","family":"Howell","sequence":"additional","affiliation":[{"name":"Texas A&amp;M University, College Station, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deja","family":"Jackson","sequence":"additional","affiliation":[{"name":"Texas A&amp;M University, College Station, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stewart G.","family":"Trost","sequence":"additional","affiliation":[{"name":"Queensland University of Technology, Brisbane, Queensland, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,6,16]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"crossref","unstructured":"Aubert S.
