Furthermore, all participants were required to measure their sleep quality daily during the trial. The control group did the same things as the intervention group apart from reading a book before bedtime. There was no restriction for using smart devices in bed. The intervention group also had to sleep in their bed, not at a hotel or a friend or loved one's house, and avoid caffeinated drinks one hour before bedtime. Another requirement was that participants had to sleep and wake up at the same time during the course of the study. Participants in the intervention group had to read for 15 to 30 minutes at bedtime for seven days.

They only needed about 550 to meet the trial standards. The study had 991 participants, with 496 in the intervention group and 495 in the control group. The group that read a book before bedtime became the intervention group, and those that went to bed without reading a book were the control group. Participants were randomly divided into two groups. Researchers targeted the online community through social media campaigns to participate in the study. The Reading Trial, a randomized trial, sought to establish the correlation between reading a book before bed and sleep quality.

A small number of correspondents hardly establishes accurate outcomes. The number of randomized trial participants also impacts the result's validity. Participants get chosen randomly into either category without knowing the trial's aim to keep the results pure. Researchers can compare two interventions and analyze their efficiency without bias based on correspondent selection. A randomized trial is the best way to determine the effect of a treatment. The only expected difference in the study is the outcome of the issue under assessment. What Is a Randomized Control Trial?Ī randomized control trial study unsystematically assigns participants to an experimental or control group. The research also emphasized the quality of randomized control trials in answering research questions. According to a study called The Reading Trial, reading in bed enhances drowsiness and improves sleep quality.
