Purpose: Test the feasibility and impact of an automated workplace mental health assessment and intervention.
Design: Efficacy was evaluated in a randomized control trial comparing employees who received screening and intervention with those who received only screening.
Setting: Workplace.
Subjects: 463 volunteers from Boston Medical Center, Boston University, and EMC and other employed adults, among whom 164 were randomized to the intervention (N = 87) and control (N = 77) groups.
Intervention: The system administers a panel of telephonic assessment instruments followed by tailored information, education, and referrals.
Measures: The Work Limitation Questionnaire, the Medical Outcomes Questionnaire Short Form-12, the Patient Health Questionnaire-9, question 10 from the Patient Health Questionnaire to measure functional impairment, and the Perceived Stress Scale-4 and questions written by study psychiatrists to measure emotional distress and social support respectively. The WHO-Five Well-being Index was administered to measure overall well-being.
Analysis: Independent sample t-tests and χ(2) tests as well as mean change were used to compare the data.
Results: No significant differences on 16 of the 20 comparisons at 3- and 6-month time points. The intervention group showed a significant improvement in depression (p ≤ .05) at 3 months and on two Work Limitation Questionnaire subscales, the Mental-Interpersonal Scale (p ≤ .05) and the Time and Scheduling Scale (p ≤ .05), at 3 and 6 months respectively with a suggestive improvement in mental health at 6 months (p ≤ .10).
Conclusions: This is a potentially fruitful area for research with important implications for workplace behavioral interventions.
