Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Arousal reduction using guided imagery
Sleep Self-Regulation Using Mental Imagery: Participants in the arousal reduction condition were instructed to imagine wearing a backpack loaded with their worries, then putting the heavy backpack down, and then experiencing the relief and freedom from tension.
Sleep Self-Regulation Using Mental Imagery
Comparison of two forms of mental imagery to instigate behaviors that assist in the sleeping process
Mental simulation of sleep behavior
Sleep Self-Regulation Using Mental Imagery: Participants in this condition received instructions to visualize a specific behavioral plan designed to meet the goal of obtaining quality sleep each night through the practice of certain behaviors. To form the behavioral plan, participants visualised changing into comfortable clothes and taking time to relax prior to going to bed, the time they planned to go to sleep, where they planned to sleep, and the bedtime routine they follow to help them to get to sleep. At bedtime, they were instructed to mentally run through a checklist of these behaviors and then do any behaviors that they had not yet completed.

Combination
Sleep Self-Regulation Using Mental Imagery: Participants in this condition were asked to practice a combination of the guided imagery (for relaxation) and mental simulation imagery for sleep-related behaviour
