The PSQI is used to measure the quality and patterns of sleep in adults. It measures seven areas of sleep: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction. For the purposes of the current study, the PSQI has been modified from a monthly questionnaire to a weekly questionnaire. This modified version will start with question 5A, (i.e., “During the past week, how often have you had trouble sleeping?”) and end with question 9 (i.e., “During the past week, how would you rate your sleep quality overall?”). It uses a Likert scale that ranges from “very bad” (3) to “very good” (0) sleep quality. It is modified from seven component scores
