The GAD-7 and the PHQ-8 exhibit the same mathematical pattern of item responses in the general population: analysis of data from the National Health Interview Survey

Abstract: Background Recent studies have shown that, among the general population, responses to depression-rating scales follow a common mathematical pattern. However, the mathematical pattern among responses to the items of the Generalized Anxiety Disorder-7 (GAD-7) is currently unknown. The present study investigated whether item responses to the GAD-7, when administered to the general population, follow the same mathematical distribution as those of depression-rating scales. … Show more

“…Previous studies have found that PHQ-9 scores are not normally distributed among adults and older adolescents ( Burdzovic Andreas & Brunborg, 2017 ; Tomitaka et al, 2018 ), and that GAD-7 item responses are similarly skewed ( Tomitaka & Furukawa, 2021 ). We confirmed these findings among our cohort of early adolescents.…”

“…The cut-off scores for minimal, mild, moderate, and severe anxiety symptoms are 0–4, 5–9, 10–14, and 15–21, respectively. A score of 10 points corresponds to a significant likelihood of GAD [ 17 ].…”

“…Smartphones record behavior patterns of users with high temporal precision and without the need for user intervention reducing the response rate. Only 59% of the users respond to PHQ surveys [ 6 ]. Global Navigation Satellite System (GNSS) data obtained from smartphones are particularly important to identify movement patterns and time spent at specific locations.…”
