Trial Outcomes & Findings for Online Peer Networked Collaborative Learning for Managing Depressive Symptoms (NCT NCT02841787)
NCT ID: NCT02841787
Last Updated: 2018-10-29
Results Overview
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.

PRIMARY outcome
Timeframe: Baseline and Week 8 - Difference in PHQ-9 scoreThe 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.

PRIMARY outcome
Timeframe: Week 8Population: Participants were included in outcome analyses if they completed assessments at both baseline and week 8; for the Individual Internet Intervention (III) arm, 9 participants met this criterion, and for Internet Intervention with Peer Support (II+PS), 21 participants met this criterion.
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.
