Cognitive and Behavioral Outcomes Among the HBM subscales, perceived severity of sleep problems significantly decreased in the exploratory group, whereas it showed an increasing trend in the directive group, yielding a significant group × time interaction in the mixed-effects model ( β =0.467, 95% CI 0.078-0.855; P =.02; Welch Δ: g =0.808).
