The effect of age and gender on GAD‐7 Score Note. For visualization purposes, data are plotted with loess curve fitting using ggplot, a method for smoothing using local polynomial regression, using a single data point (mean) for each age time point. GAD‐7 scores showed a significant decline across the lifespan for both genders (R 2 = 0.05, F (1, 7,062) = 116.00, p < 0.001). Males and females showed significantly different GAD‐7 scores, with women reporting higher levels of anxiety (F (1, 6,957) = 108.30, p < 0.001). GAD, generalized anxiety disorder
