Process indicators were assessed using methods such as questionnaires and track-and-trace data.All participants (32%; N = 369) received screening and personalized feedback. In group 1, 41% went to a preventive consultation with their occupational physician. Protocol adherence of participating occupational physicians (n = 5) was high. They regarded the WHS mental module to be meaningful. In group 2, 16% logged into an e-mental health intervention. Most participants would appreciate a future offer of the WHS.The WHS mental module was well received and fitted in the occupational health service activities.
