Interactive Voice-Based Administration of the PHQ-9

Study Overview
=================
Brief Summary
-----------------
This study investigates a new delivery method for the Patient Health Questionnaire - 9 (PHQ-9), a clinically accepted tool for diagnosing major depressive disorder. The new tool records auditory responses to the assesment and the study will examine if the instrument is effective at capturing participant depression levels. If proven effective, future studies may investigate if the new format can be used to improve at home clinical care.

Detailed Description
-----------------
This study is an investigation of a new delivery system of the Patient Health Questionnaire - 9 (PHQ-9), a clinically accepted tool for diagnosing major depressive disorder. The purpose of the study is to examine if the new delivery system of the PHQ-9 is effective at capturing participant depression levels. The new version uses a Mirror device, which is similar to a smart television with a mirror interface. The device records auditory responses to the PHQ-9 through Amazon Alexa. We will be comparing the responses from the Mirror device to those given on the clinically established paper format. If proven effective at capturing depression levels of patients, future studies may investigate if the new format can be used to improve at home clinical care.

Design Details

Primary Purpose: Diagnostic
Allocation: Randomized
Intervention Model: Crossover Assignment
Interventional Model Description: This study will be a repeated measure, mixed methods design (i.e., it will contain both qualitative and quantitative components). Newly admitted patients will be asked to complete the questionnaires (i.e., PHQ-9 and the UEQ) at two different time points (i.e., Baseline and 1-month follow-up). In order to reduce or control for order effects, the procedure will be counterbalanced.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Paper Baseline<br>Half of the participants will complete the PHQ-9 in the traditional paper format at their first appointment. At their second appointment 1-month later, they will complete the PHQ-9 on the Mirror device equipped with Amazon Alexa. | Diagnostic Test: PHQ-9 - Mirror format<br>* The intervention we will be using is a new delivery system of the PHQ-9 using an Amazon Alexa equipped Mirror device. This Mirror device is similar to a smart television with a mirror interface. The device records auditory responses to the PHQ-9. We will be comparing the responses from the Mirror device to those given on the clinically established paper format.<br>* Other names: PHQ-9 - Amazon Alexa equipped device;|
