Primary Outcome Measures

Name	Time	Method
Assessment of anxiety using Hamilton Anxiety Rating Scale (HAM-A) scale	30 days	Hamilton Anxiety Rating Scale (HAM-A) (1) was assessed using a questionnaire and scored on a scale of 0 to 4, with 0 (no presence of anxiety) to 4 (severe anxiety).

Assessment of depression using Hamilton Depression Rating Scale (HDRS) scale	30 days	Hamilton Depression Rating Scale (HDRS) (1) was assessed using a questionnaire and scored using a scale of 0 to 20, with 0-7 (within normal range or remission) while a score of 20 (indicating moderate depression.; (1) Hamilton, M. A rating scale of depression. J. Neurol. Neurosurg. Psychiatry, 1960, 23, 56-62.
Assessment of perception of stress in subjects that experience moderate levels of stress using Perceived Stress Scale (PSS)	30 days	Perceived stress was assessed with Perceived Stress Scale (PSS) using a validated questionnaire on a score of 0 to 40, with 0 (no stress) and 20 or above (higher perceived stress) at day 1, day 7 and at day 30.

Secondary Outcome Measures

Name	Time	Method
Assessment of mood using Profile of Mood States (POMS) scale	30 days	Assessment of Profile of Mood States (POMS) was measured on a 5 point scale of 0 to 5, with 0 (not at all moody) to 4 (extremely moody),
Assessment of sleep using Restorative Sleep Questionnaire, Weekly (RSQ-W) version scale	30 days	Restorative Sleep Questionnaire, Weekly (RSQ-W) is a nine-item survey that measures how restful a person feels after sleeping for the past week. The RSQ-W scale scores range from 0-100, with higher scores indicating more restorative sleep. To convert the average score to a 0-100 scale, use the formula: RSQ-W Total Score = {RSQ-W Average Score Across Completed Items - 1.0}\*25.
