Measuring Anxiety and Depression in Adolescents: Psychometric Properties of the Overall Anxiety and Depression Severity and Impairment Scales.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAnxiety and depression are among the most prevalent mental health disorders in adolescence. 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.
methodsThe psychometric properties of the OASIS-A and ODSIS-A 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-based comparisons and cutoff scores.
resultsFactor analysis supported a unidimensional structure for both the OASIS-A and ODSIS-A. The internal consistency was excellent for both scales (Cronbach's α and McDonald's ω for the OASIS-A were 0.90 and for ODSIS-A were 0.94) and measurement invariance across gender was established. The OASIS-A and ODSIS-A showed significant correlations with measures of anxiety, depression, quality of life and mental well-being, in theoretically expected directions. Additionally, girls reported significantly higher levels of anxiety and depression. Optimal cutoff scores were identified as 7 for OASIS-A and 5 for ODSIS-A.
conclusionsThis study presents the first psychometric evaluation of the OASIS-A and ODSIS-A, underscoring the utility of brief self-report measures for the severity and impairment associated with anxiety and depression in adolescents. Findings also support the use of these tools for screening purposes, particularly in school settings.
