Clinical Trial Summary

This study will evaluate a Smartphone intervention for depression and anxiety that uses machine learning to tailor treatment for patients. The intervention, referred to as IntelliCare, delivers patient-specific treatment material and motivational messaging via a mobile phone, to help individuals with depression and/or anxiety. Information and data received from the patient will inform the tailored treatment approach through machine learning. The purpose of this study is to obtain preliminary information on the feasibility and effectiveness of IntelliCare in improving symptoms of depression and anxiety.

Description:

Major depressive disorder (MDD) is a common mental disorder, with up to 10.3% of the population experiencing the disorder in a given 12-month period. The relationship between depression and anxiety has been well documented. Depression is a significant predictor of future anxiety, and anxiety is a significant predictor of future onset of depression. Indeed, studies find that more than 50% of all individuals with MDD also have a current anxiety disorder. Although effective treatments have been developed over the years to address depression and anxiety, the lack of personalization and inability to adapt to patient needs or preferences contributes to poor treatment adherence and outcomes. We are developing an intelligent treatment system that uses state of the art machine learning approaches within a mobile intervention application to treat MDD and anxiety. Machine learning, a branch of artificial intelligence, focuses on the development of algorithms that automatically improve and evolve based on collected data. The intervention, called IntelliCare, uses a mobile application to continuously collect patient data and adapt intervention content and motivational messaging to create a highly tailored and user-responsive treatment system. During the pilot study, 200 participants with Major Depression and/or Anxiety will use Intellicare apps for up to 8 weeks and may be invited to provide feedback about their experience at two follow-up time points: weeks 4 and 8. All participants will first undergo initial assessments that will include a telephone interview and a series of online questionnaires about their mood. Eligible participants will receive up to 8 weeks of access to the IntelliCare system, which consists of apps with lessons and tools designed to teach skills for mood management. It is suggested that participants utilize the mobile phone tools every day. Each week, participants will receive a brief motivational intervention from a coach. This coach will also be available to participants via email throughout the 8 week study. We will use data from the pilot study to examine whether IntelliCare is a feasible and effective intervention. Data collected will also be used to develop and evaluate machine learning methods which will be used in the subsequent AIM trials.

Eligibility

Inclusion Criteria:

• Meets criteria for clinically significant symptoms of depression or anxiety using self-report measures used in screening for depression, as well as interviewer administered measures to ensure symptoms are not transitory and have been present for at least two weeks.
• Is familiar with the use of mobile phones
• Has an Android phone and is willing download the IntelliCare apps on their own device

• Is at least 19 years of age
• Is able to give informed consent

Exclusion Criteria:

• Has visual, hearing, voice, or motor impairment that would prevent completion of study and treatment procedures
• Has any psychiatric condition for which participation in a clinical trial of psychotherapy may be either inappropriate or dangerous (e.g., psychotic disorders, bipolar disorders, dissociative disorders, obsessive compulsive disorder, severe post traumatic stress disorder, etc.).
• Exhibits severe suicidality, including ideation, plan, and intent.
• Currently receiving psychotherapy or planning to receive psychotherapy during the 8 weeks of the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Patient Health Questionnaire - 9 (PHQ-9) - Depression Severity Module	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.	Baseline, Week 4, and Week 8
Primary	GAD-7 (Generalized Anxiety Disorder Scale-7)	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.	Baseline, Week 4, and Week 8
Secondary	Mean Number of Treatment App Use Sessions by Study Week		Weekly for Two Months
