NCT05953779

Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

  • Hamilton-Depression Rating Scale

    (Range 0-52, higher scores denote greater depression)

    Change between pre-intervention and 1 month post-intervention

  • Montgomery-Asberg Depression Rating Scale

    (Range 0-60, higher scores denote greater depression)

    Change between pre-intervention and 1 month post-intervention

  • Hamilton-Anxiety Rating Scale

    (Range 0-56, higher scores denote greater anxiety); will be used in lieu of Hamilton-Depression ratings for individuals whose Hamilton-Anxiety scores are higher than their Hamilton-Depression scores.

    Change between pre-intervention and 1 month post-intervention

Secondary Outcomes (3)

  • PHQ-8

    Immediately prior to intervention, and again at 1 and 3 months post-intervention

  • GAD-7

    Immediately prior to intervention, and again at 1 and 3 months post-intervention

  • DASS

    Immediately prior to intervention, and again at 1 and 3 months post-intervention

Other Outcomes (5)

  • PANAS

    Up to six weeks prior to intervention, and again at 1 and 3 months post-intervention

  • ERQ

    Up to six weeks prior to intervention, and again at 1 and 3 months post-intervention

  • DERS-18

    Up to six weeks prior to intervention, and again at 1 and 3 months post-intervention

  • +2 more other outcomes

Study Arms (2)

Personalized Intervention

EXPERIMENTAL

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.

Behavioral: Clinician-administered Need-focused Single Session Intervention

Non-personalized Intervention

ACTIVE COMPARATOR

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.

Behavioral: Clinician-administered Need-focused Single Session Intervention

Interventions

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.

Masking Details
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.
