Objectives: We examined whether an online mentoring health intervention (OMHI) would strengthen characteristics that can prevent risky behaviors: resilience, perceived social support, psychological distress, and crisis concerns. Methods: Fifty-six secondary-school students participated, 27 in the intervention group and 29 in the control group (mean age 16.18, SD 0.83 vs. 16.62, SD 0.82, respectively). The study took place between March and August 2020. Results: The intervention group was less resilient pre-test, with similar resilience levels as the control group post-test. Intervention group participants presented a significantly higher crisis level pre- and post-test than the control group, as well as an increase in resilience (effect size = 1.88) and social support (effect size = 1.22), while psychological distress significantly decreased (effect size = \u22121.03). Both groups (intervention vs. control) predicted changes from pre-to-post test for resilience and crisis (adjusted R2 = 0.33, p = 0.001 and R2 = 0.49, p = 0.0001 respectively). Conclusions: OMHI participation was associated with improved resilience and social support, and decreased psychological distress, making it an effective strategy in health promotion for at-risk youth. An online intervention program combining mentoring in physical activity and interpersonal connections may constitute an effective health promotion strategy for at-risk youth, especially in times of crisis.<\/jats:p>","DOI":"10.3390\/children9111704","type":"journal-article","created":{"date-parts":[[2022,11,7]],"date-time":"2022-11-07T02:43:51Z","timestamp":1667789031000},"page":"1704","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["The Effects of a Physical Activity Online Intervention Program on Resilience, Perceived Social Support, Psychological Distress and Concerns among At-Risk Youth during the COVID-19 Pandemic"],"prefix":"10.3390","volume":"9","author":[{"given":"Michal","family":"Glaser","sequence":"first","affiliation":[{"name":"Department of Health Systems Management, School of Health Sciences, Ariel University, Ariel 4077625, Israel"},{"name":"Health Promotion & Wellbeing Research Center, Ariel University, Ariel 4077625, Israel"}]},{"given":"Gizell","family":"Green","sequence":"additional","affiliation":[{"name":"Department of Nursing, School of Health Sciences, Ariel University, Ariel 4077625, Israel"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1849-7206","authenticated-orcid":false,"given":"Avi","family":"Zigdon","sequence":"additional","affiliation":[{"name":"Department of Health Systems Management, School of Health Sciences, Ariel University, Ariel 4077625, Israel"},{"name":"Health Promotion & Wellbeing Research Center, Ariel University, Ariel 4077625, Israel"},{"name":"Disaster Research Center, Ariel University, Ariel 4077625, Israel"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0714-4798","authenticated-orcid":false,"given":"Sharon","family":"Barak","sequence":"additional","affiliation":[{"name":"Department of Nursing, School of Health Sciences, Ariel University, Ariel 4077625, Israel"},{"name":"Department of Pediatric Rehabilitation, The Chaim Sheba Medical Center at Tel Hashomer, Ramat-Gan 5262000, Israel"}]},{"given":"Gili","family":"Joseph","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Faculty of Science, Seminar Kibbutzim College, Tel Aviv 6250769, Israel"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9850-7771","authenticated-orcid":false,"given":"Adilson","family":"Marques","sequence":"additional","affiliation":[{"name":"Faculdade de Motricidade Humana, Centro Interdisciplinar para o Estudo da Performance Humana, Universidade de Lisboa, 1649-004 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5461-7706","authenticated-orcid":false,"given":"Kwok","family":"Ng","sequence":"additional","affiliation":[{"name":"School of Educational Sciences and Psychology, University of Eastern Finland, 70211 Kuopio, Finland"},{"name":"Physical Activity for Health Research Cluster, Department of Physical Education and Sport Sciences, University of Limerick, V94 T9PX Limerick, Ireland"}]},{"given":"Itamar","family":"Erez-Shidlov","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Wingate College, Netanya 4290200, Israel"}]},{"given":"Lani","family":"Ofri","sequence":"additional","affiliation":[{"name":"Department of Nursing, School of Health Sciences, Ariel University, Ariel 4077625, Israel"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6070-6193","authenticated-orcid":false,"given":"Riki","family":"Tesler","sequence":"additional","affiliation":[{"name":"Department of Health Systems Management, School of Health Sciences, Ariel University, Ariel 4077625, Israel"},{"name":"Health Promotion & Wellbeing Research Center, Ariel University, Ariel 4077625, Israel"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1186\/s40798-020-00254-x","article-title":"School-related physical activity interventions and mental health among children: A systematic review and meta-analysis","volume":"6","author":"Andermo","year":"2020","journal-title":"Sports Med.
