Note. Pt. Ed.=Patient education condition; % above RCI=Percentage of individuals in each condition who experienced a meaningful and reliable change from pre-intervention to post-intervention, based on the RCI for that measure. RCI’s were not calculated for sleep onset latency and wake after sleep onset because those scores were based a single item scale.
