简要总结
Depression is one of the most prevalent mental disorders to afflict adults. It seriously impacts role functioning and often takes a recurrent or chronic course. Because most adults who suffer from depression never receive treatment, there is a critical need to develop interventions that can be easily implemented and widely disseminated. Interventions that reduce the performance-impairing symptoms of subclinical depression and prevent the onset of major depression can improve employee well-being, while reducing healthcare costs and improving productivity. This project produced a mobile-web program to activate cognitive behavioral skills in workers with subthreshold depression, reduce depression symptoms, improve functioning in the workplace, and potentially reduce the risk for escalation to full-syndrome depression.
详细描述
The responsive mobile-web MoodHacker app was designed to: (a) educate users about depression; (b) educate users about the logistics and benefits of mood and activity monitoring; (c) promote daily mood and activity monitoring; (d) help users increase their positive activity engagement; (e) help users decrease negative thinking and increase positive thinking; and (f) promote daily practice of the skills taught.
Program content was adapted from the Coping with Depression group therapy course [18], enhanced with mindfulness-based [22] and other evidence-based positive psychology strategies [23-25]. Content for the application was refined based on input from experts in the field who had extensive experience working with adult employees at risk for depression. Additional program modifications were made based on data from individual interviews and iterative user testing with the population of interest during the formative and production phases of the project.
The MoodHacker user experience is structured around twelve learning objectives delivered through daily emails, in-app messaging, and in the "Articles & Videos" library. Daily emails (Figure 1) are sent to engage users in program content, provide sequenced guidance through the learning objectives in the articles and whiteboard-style videos, give tips for getting the most out of MoodHacker, and prompt the user to track their mood and activities daily. Users are encouraged to view the articles and videos as ordered, but viewing is not restricted, and users can view content according to their interest. The emails, articles and videos promote practice of the featured cognitive and behavioral skills outside the app experience.

研究组 & 干预措施
MoodHacker
Participants in the treatment condition were emailed a link to the MoodHacker mobile-web app and instructed to use the program for the next six weeks. Participants were asked to complete 2 follow-up assessments, 6 weeks and 10 weeks after baseline.
干预措施: MoodHacker (Behavioral)
Alternative Care
Alternative care participants were emailed and encouraged to browse links to vetted online information about depression. Participants were asked to complete 2 follow-up assessments, 6 weeks and 10 weeks after baseline and were given access to the MoodHacker program after the 10-week assessment
干预措施: Alternative Care (Behavioral)
结局指标
主要结局
Depression symptoms as assessed by the Patient Health Questionnaire-9 (PHQ-9)
时间窗: 10 week follow-up
Depressive symptomatology was assessed at each assessment point using the self-reported Patient Health Questionnaire-9 scale to assess the nine DSM-IV major depression symptoms. The PHQ-9 is a self-report version of the Primary Care Evaluation of Mental Disorders (PRIME-MD) and has been shown to be a reliable and valid brief depression assessment tool.
