However, there is a lack of efficient instruments that simultaneously assess both the severity and impairment associated with these symptoms. This study aims to adapt and further validate the Overall Anxiety Severity and Impairment Scale (OASIS) and the Overall Depression Severity and Impairment Scale (ODSIS) for adolescents.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The psychometric properties of the OASIS\u2010A and ODSIS\u2010A were examined in a community sample of 598 adolescents (51% male) from Portuguese public schools. Analyses included factor structure, internal consistency, measurement invariance, construct validity, gender\u2010based comparisons and cutoff scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Factor analysis supported a unidimensional structure for both the OASIS\u2010A and ODSIS\u2010A. The internal consistency was excellent for both scales (Cronbach's\n                      <jats:italic>\u03b1<\/jats:italic>\n                      and McDonald's\n                      <jats:italic>\u03c9<\/jats:italic>\n                      for the OASIS\u2010A were 0.90 and for ODSIS\u2010A were 0.94) and measurement invariance across gender was established. The OASIS\u2010A and ODSIS\u2010A showed significant correlations with measures of anxiety, depression, quality of life and mental well\u2010being, in theoretically expected directions. Additionally, girls reported significantly higher levels of anxiety and depression. Optimal cutoff scores were identified as 7 for OASIS\u2010A and 5 for ODSIS\u2010A.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study presents the first psychometric evaluation of the OASIS\u2010A and ODSIS\u2010A, underscoring the utility of brief self\u2010report measures for the severity and impairment associated with anxiety and depression in adolescents.
