Trial Outcomes & Findings for IntelliCare: Artificial Intelligence in a Mobile Intervention for Depression and Anxiety (AIM) (NCT NCT02176226)

NCT ID: NCT02176226

Last Updated: 2023-04-26

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.

PRIMARY outcome

Timeframe: Baseline, Week 4, and Week 8

Population: Two participants missed week 4 assessment; and two participants missed week 8 assessment. This is why number analyzed in Week 4 row and Week 8 row differs from overall.

The GAD-7 is a self-administered 7 item instrument that uses some of the DSM-V criteria for GAD (General Anxiety Disorder) to identify probable cases of GAD along with measuring anxiety symptom severity. GAD-7 total score for the seven items ranges from 0 to 21. Higher values represent a worse outcome. Specifically, scores of 1-4 indicate minimal anxiety symptoms; 5-9 is mild anxiety symptoms; 10-14 is moderate anxiety symptoms; and 15-21 is severe anxiety symptoms.
