Overview
Brief Summary
The goal of this field trial is to tailor and test a web-based intervention in adults 65 years of age or older. Two versions of the web-based intervention have been created and will be tested--one with an online social network and one without an online social network. The purpose of this study is to: pilot a novel intervention, examine methods to improve adherence to web-based interventions (e.g., peer network); collect data on feasibility, acceptability, and efficacy of an web-based intervention for late life depression; and ultimately, to overcome the numerous barriers to treating depression in later life.

Outcomes
Primary Outcomes
Patient Health Questionnaire - 9 (PHQ-9) - Depression Severity Module
Time Frame: Baseline and Week 8 - Difference in PHQ-9 score
The PHQ-9 measures degree of depression severity. Possible range of scores for the PHQ-9 is 0-27. Higher values represent a worse outcome. Specifically, scores of 0-4 indicate minimal or no depression; 5-9 is mild; 10-14 is moderate; 15-19 is moderately severe; and 20-27 is severe. The data table below shows PHQ-9 pre- and post- intervention score differences by group.
Mean Number of Sessions Across the 8-week Trial
Time Frame: 8 weeks
Average Coaching Time Per Participant by Group
Time Frame: 8 weeks
The average time spent on messages and calls and on group moderation.
System Usability Scale (SUS)
Time Frame: Week 8
The System Usability Scale (SUS) is a usability scale that can be used for global assessments of systems usability. It consists of a 10 item questionnaire with five response options for respondents; from Strongly agree to Strongly disagree. Originally created by John Brooke in 1986, it allows you to evaluate a wide variety of products and services, including hardware, software, mobile devices, websites and applications. The participant's scores for each question are converted to a new number, added together and then multiplied by 2.5 to convert the original scores of 0-40 to 0-100. A SUS score above a 68 would be considered above average and anything below 68 is below average.
