Other outcomes

  1. Change From Baseline in World Health Organization Health and Work Performance Questionnaire, Clinical Trials 7-Day Version (HPQ), Dollars of Income Lost Due to Work Presenteeism (WP)Score, at Week-12 Endpoint

    WP score was calculated by taking midpoint of annual before-tax income reported on HPQ. A multiplier of 1.25 produced estimated direct \& indirect (i.e. benefits) income. Annual hours expected to work were calculated from expected daily work hours, multiplied by 236 days. Hourly, indirect income was total direct + indirect income, divided by # of expected annual work hours. Indirect hours lost annually for WP=hours expected to be worked annually times WP percent, times hourly rate=dollars earned, and then subtracted from total direct + indirect income=dollars lost annually due to WP.

    Time frame: Baseline, 12 Weeks

  2. Change From Baseline in World Health Organization Health and Work Performance Questionnaire, Clinical Trials 7-Day Version (HPQ), Dollars of Income Lost Due to Work Absenteeism Score at Week-12 Endpoint

    Self-administered assessment used to determine a participant's work performance in terms of employment status, absenteeism if employed, productivity while at work, usual occupation, and annual income. Tool assesses the potential impact of change in depressive symptoms on work productivity and its associated employer costs. Scale ranges from 0 to 100% of work days in past 30 days. Absenteeism and presenteeism were combined into a measure of total lost work performance by adding absenteeism to the value (\[100-absenteeism\] × \[100-presenteeism\]). Mean change baseline to endpoint.

    Time frame: Baseline, 12 weeks

  3. Change From Baseline in World Health Organization Health and Work Performance Questionnaire, Clinical Trials 7-Day Version (HPQ), Absenteeism at 12-Week Endpoint

    Self-administered assessment used to determine a subject's work performance in terms of employment status, absenteeism if employed, productivity while at work, usual occupation, and annual income. Tool assesses the potential impact of change in depressive symptoms on work productivity and its associated employer costs. Defined on a 0-100 scale for the percentage of work days the respondent missed in the past 30 days. Absolute absenteeism: actual hours worked minus expected hours equals number of missed work days. Mean change baseline to endpoint is reported.

    Time frame: Baseline, 12 Weeks

  4. Change From Baseline in World Health Organization Health and Work Performance Questionnaire, Clinical Trials 7-Day Version (HPQ), Presenteeism Score, at Week-12 Endpoint

    Self-administered assessment used to determine a participant's work performance (employment status, absenteeism if employed, productivity while at work, usual occupation, \& annual income). Tool assesses the potential impact of change in depressive symptoms on work productivity \& its associated employer costs using a 0-100 scale in which 0 meant doing no work at all on days spent at work and 100 meant performing at the level of a top worker. Absolute presenteeism: difference between "score for self" and "score for average worker in same job". Mean change baseline to endpoint is reported.

SecondaryChange From Baseline in Sheehan Disability Scale (SDS) Global Functional Impairment Score at 12-Week Endpoint (Functional Outcome Measure)

The SDS is a participant-rated anchored visual analog scale to assess disability across the three domains of work/school, social life, and family life, with each item scored from 0 (not at all) to 10 (very severely), with a summarization of the 3 items to evaluate global functioning. The Global Functional Impairment Score is a total score score that ranges from 0 (unimpaired) to 30 (highly impaired), and was used to derived the mean change from baseline to endpoint.

Other pre-specifiedChange From Baseline in World Health Organization Health and Work Performance Questionnaire, Clinical Trials 7-Day Version (HPQ), Dollars of Income Lost Due to Work Presenteeism (WP)Score, at Week-12 Endpoint

WP score was calculated by taking midpoint of annual before-tax income reported on HPQ. A multiplier of 1.25 produced estimated direct \& indirect (i.e. benefits) income. Annual hours expected to work were calculated from expected daily work hours, multiplied by 236 days. Hourly, indirect income was total direct + indirect income, divided by # of expected annual work hours. Indirect hours lost annually for WP=hours expected to be worked annually times WP percent, times hourly rate=dollars earned, and then subtracted from total direct + indirect income=dollars lost annually due to WP.

Self-administered assessment used to determine a participant's work performance in terms of employment status, absenteeism if employed, productivity while at work, usual occupation, and annual income. Tool assesses the potential impact of change in depressive symptoms on work productivity and its associated employer costs. Scale ranges from 0 to 100% of work days in past 30 days. Absenteeism and presenteeism were combined into a measure of total lost work performance by adding absenteeism to the value (\[100-absenteeism\] × \[100-presenteeism\]).
