Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a two-site randomized controlled trial, with two goals. First, the investigators aim to demonstrate that single-session interventions for mild-to-moderate anxiety and depression can generate statistically significant symptom change as a main effect across control and experimental (i.e. personalized) conditions. Second, the investigators hope to establish the additional incremental efficacy of personalization via person-specific intensive longitudinal data collection and analysis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a two-site randomized controlled trial, with two goals. First, the investigators aim to demonstrate that single-session interventions for mild-to-moderate anxiety and depression can generate statistically significant symptom change as a main effect across control and experimental (i.e. personalized) conditions. Second, the investigators hope to establish the additional incremental efficacy of personalization via person-specific intensive longitudinal data collection and analysis.

All single-session interventions will be 90-minutes in length. At the conclusion of the intervention session, participants will receive suggestions for daily homework practice to complete and a flash drive with a copy of their session audio to review at their discretion. Participants will also meet with the therapist for a 10-minute remote check-in two weeks following the single session.

All interventions include standard psychoeducational components. Participants randomized to the personalization arm of the study will be given an intervention matched to their most pressing psychosocial need. Participants randomized to the control condition will receive a standard intervention (at the UCB site) or a randomly selected one (at the BIU site). Both the standard intervention and the specific ones were designed to be broadly efficacious for depression and anxiety symptomatology.

The psychosocial needs which serve as the focus of the interventions are derived from motivation and affect regulation models and include emotional stability, predictability, acceptance, competence, self-esteem, autonomy, and pleasure. The primary unmet need for each individual will be determined by a conditional entropy algorithm. Simply, the presence versus absence of subjective distress will be measured eight times per day for 30 days. Concurrently, the presence versus absence of need frustration will also be measured eight times per day for 30 days. Utilizing a k-fold cross-validated estimation, conditional entropy will be used to determine the need that best reduces the uncertainty in subjective distress (that is, best explains its presentation probabilistically).

RANDOMIZED

Intervention Model

PARALLEL

Randomized Control Trial with 2 conditions: Experimental condition (personalized-selected intervention) and control condition (randomly-selected or standard intervention focused on emotion-regulation).
Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Caregivers Outcome Assessors
The participants and any care provider and study personnel who interact with them will be blind to condition. The PI will utilize a randomization table to allocate participants to condition, and will inform the front-line study personnel and through them, the care provider, regarding which intervention to use without specifying whether it was personalized or randomly-chosen. The outcomes assessor will be blind even to the type of intervention utilized.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Personalized Intervention

The intervention approach taken in this RCT is focused on unmet psychological needs (predictability, belonging, competence, self-worth, autonomy, and playfulness). For each need, a specific 90-minute intervention has been developed.

The primary unmet need for each individual will be determined by a conditional entropy algorithm. Simply, the presence versus absence of subjective distress will be measured eight times per day for 30 days. Concurrently, the presence versus absence of need frustration will also be measured eight times per day for 30 days. Utilizing a k-fold cross-validated estimation, conditional entropy will be used to determine the need that best reduces the uncertainty in subjective distress (that is, best explains its presentation probabilistically).

At both sites, the experimental condition will consist of an algorithmically-chosen intervention. The choice will be made based on data collected during thirty days of ecological momentary assessment.

Group Type EXPERIMENTAL

Clinician-administered Need-focused Single Session Intervention

Intervention Type BEHAVIORAL

All single-session interventions will be 90-minutes in length. At the conclusion of the intervention session, participants will receive suggestions for daily homework practice to complete and a flash drive with a copy of their session audio to review at their discretion. They will also meet with the therapist for a 10-minute remote check-in two weeks following the single session. All interventions include standard psychoeducational components. Both the standard intervention and the specific ones were designed to be broadly efficacious for depression and anxiety symptomatology. The psychosocial needs which serve as the focus of the interventions are derived from motivation and affect regulation models.

Non-personalized Intervention

The intervention approach taken in this RCT is focused on unmet psychological needs (predictability, belonging, competence, self-worth, autonomy, and playfulness). For each need, a specific 90-minute intervention has been developed.

At the BIU site, the active control condition will consist of an intervention chosen randomly (out of the six mentioned above).

At the UCB site, the active control condition will consist of a standard intervention addressing emotion regulation difficulties.
