Outcome Measures
Primary Outcomes (3)
Depression, Anxiety and Stress Scale-21 (DASS-21)
Assessment of the mean change in the results of Depression, Anxiety and Stress Scale-21 (DASS-21) from baseline. There are 21 items consisting of three scales (Depression, Anxiety and Stress) contains 7 items and scores from each scale can range from 0-56. The lower the scores for each scale indicates a better outcome.
28 days
State-Trait Anxiety Inventory (STAI)
Assessment of the mean change in the results of the State-Trait Anxiety Inventory (STAI) from baseline. This is a 20-item questionnaire which includes separate measures of state and trait anxiety. The total scores range from 0-63. The lower the score indicates a better outcome.
28 days
Perceived Stress Scale (PSS-14)
Assessment of the mean change in the results of the Perceived Stress Scale (PSS-14) from baseline. There are 14 items and total scores range from 0-56. The lower the score indicates a lower level of stress.
