Abbreviations: BWAW, Be Well at Work; IC, integrated care; T1, 4-month follow-up; T2, 8-month follow-up.
a
Estimated based on mixed models.
b
Measured using the Work Limitations Questionnaire (range, 0-25).
c
Measured using the Patient Health Questionnaire 9-item symptom severity score (range, 0-27).
d
Measured as the mean percentage of total hours missed from work in the past 2 weeks owing to health conditions or medical care divided by the number of hours usually spent working (range, 1-100).
