A multiple linear regression model was constructed that evaluated the association between 6 PROMIS domains and WISSQ ratings, adjusting for age, sex, and self-reported physical activity volume. To address the secondary purpose, linear regression models with an interaction term were used to examine the association between each PROMIS domain and age with sport specialization.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 251 uninjured adolescent athletes completed the study (mean \u00b1 SD age, 15.9 \u00b1 1.4 years). The mean WISSQ rating was 54.1 (SD, 15.4). Results from the multivariable linear regression model indicated that higher depressive symptoms (\u03b2 = 0.46; 95% CI, 0.16-0.76;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .003) and pain interference ratings (\u03b2 = 0.30; 95% CI, 0.02-0.57;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .03) were significantly associated with higher WISSQ ratings, after adjusting for baseline physical activity, age, sex, and history of anxiety or depression diagnosis. For the secondary purpose, there was a significant interaction between fatigue and age group on sport specialization (\u03b2 coefficient = 0.49; 95% CI, 0.02-0.95;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .04). The relationship between fatigue and sport specialization differed by age: a stronger association occurred among older adolescents than younger adolescents. There were no other age \u00d7 QoL interactions.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This study demonstrated that higher depressive symptoms and pain interference ratings were significantly associated with higher WISSQ ratings. In addition, there was a significant interaction between fatigue and age group, with a stronger association identified among older adolescents. Higher specialized and older adolescent athletes may be more at risk for developing mental health\/QoL concerns and may benefit from more targeted screening.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/23259671261467554","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T09:09:26Z","timestamp":1786007366000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Association of Mental Health, Quality of Life, and Sport Specialization Using the Wisconsin Sport Specialization Questionnaire Among Adolescent Athletes"],"prefix":"10.1177","volume":"14","author":[{"given":"Rachel","family":"Meyers","sequence":"first","affiliation":[{"name":"Sports Medicine Center, Children's Hospital Colorado, Aurora, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Petersen","sequence":"additional","affiliation":[{"name":"Sports Medicine Center, Children's Hospital Colorado, Aurora, Colorado, USA"},{"name":"Department of Orthopedics, University of Colorado School of Medicine, Aurora, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronica","family":"Hogg-Cornejo","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, University of Colorado School of Medicine, Aurora, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5546-4668","authenticated-orcid":false,"given":"Emily","family":"Sweeney","sequence":"additional","affiliation":[{"name":"Sports Medicine Center, Children's Hospital Colorado, Aurora, Colorado, USA"},{"name":"Department of Orthopedics, University of Colorado School of Medicine, Aurora, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aubrey","family":"Armento","sequence":"additional","affiliation":[{"name":"Sports Medicine Center, Children's Hospital Colorado, Aurora, Colorado, USA"},{"name":"Department of Orthopedics, University of Colorado School of Medicine, Aurora, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2955-0191","authenticated-orcid":false,"given":"David","family":"Howell","sequence":"additional","affiliation":[{"name":"Sports Medicine Center, Children's Hospital Colorado, Aurora, Colorado, USA"},{"name":"Department of Orthopedics, University of Colorado School of Medicine, Aurora, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory","family":"Walker","sequence":"additional","affiliation":[{"name":"Sports Medicine Center, Children's Hospital Colorado, Aurora, Colorado, USA"},{"name":"Department of Orthopedics, University of Colorado School of Medicine, Aurora, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,6]]},"reference":[{"key":"e_1_3_2_2_2","unstructured":"Are fewer kids playing sports?
