Positive Affect Treatment for Adolescents With Early Life Adversity (PAT4ELA)

April 29, 2026 updated by: Kate Kuhlman, University of California, Irvine

Mitigating Depression Among Adversity Exposed Adolescents Using Positive Affect Therapy

Youth exposed to early life adversity (ELA) are known to be at greater risk for depression and suicidality and account for almost half of the youth suffering from psychiatric diseases today. Youth exposed to ELA consistently report symptoms of anhedonia as well as dysregulated positive affect. The present project will test the efficacy of PAT in a sample of ELA-exposed adolescents in order to determine whether PAT increases positive affect, and subsequently symptoms of depression. For the initial pilot phase of the investigation, the investigators will recruit up to 30 adolescents exposed to two or more childhood adversities (ACEs) who do not currently have major depressive disorder, and randomize them (1:1) to either participate in PAT or a waitlist control condition. For the second phase of the investigation, the investigators will recruit up to 300 adolescents exposed to two or more childhood adversities (ACEs) who do not currently have major depressive disorder, and randomize them (1:1) to either participate in PAT or supportive psychotherapy. For both phases, at study enrollment, then 4-, 8, and 12-months thereafter the investigators will measure positive affect and depressive symptoms (including anhedonia and reward sensitivity). The results of this study will be used to inform whether PAT has the potential to prevent major depressive episodes among adversity-exposed youth.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • aged 12-16
  • exposed to 2 or more adverse childhood experiences (ACEs)

Exclusion Criteria:

  • currently taking an antidepressant or any medications known to influence immune functioning on a daily basis (e.g., steroidal medications to treat asthma or allergies)
  • current or past history of manic or psychotic symptoms
  • parent-reported diagnosis of intellectual disability or autism spectrum disorder
  • chronic medical conditions (e.g., cancer, rheumatoid arthritis, diabetes, multiple sclerosis),

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Waitlist
Experimental: Positive affect treatment
PAT is a 15-week cognitive-behavioral therapy that focuses on increasing reward motivation and sensitivity at the neural, behavioral, and affective levels of analysis. These observed effects occur through PAT's effects on reward sensitivity and positive affect. Participants will be assigned to a therapist with training in cognitive-behavioral therapy who will meet with them weekly via telehealth.
Behavioral: Positive affect treatment
PAT includes 15 weekly, 1-hour sessions. The treatment is composed of three modules targeting behaviors (Sessions 1-7), cognitions (Sessions 8 -10), and compassion (Sessions 11-14), with skills being reinforced in a cumulative manner in subsequent sessions. The final session in the original treatment (Session 15) addressed relapse prevention, which will be adapted to focus on further reinforcing and generalizing learned skills. The treatment includes guided activities that target different aspects of positive affectivity such as reward approach-motivation, reward learning, and reward attainment.
Other Names:
  • PAT
Active Comparator: Supportive Psychotherapy (SUP)
Participants randomized to SUP will receive 15 weeks of SUP from a doctoral student in clinical psychology. SUP is a flexibly-delivered, manualized evidence-based treatment that focuses on reinforcing a patient's existing coping strategies while fostering a positive therapeutic relationship. Supportive psychotherapy provides a time, attention, and social support control that is similar to a placebo but likely to be perceived as relevant to this population.
Behavioral: Supportive psychotherapy (SUP)
Supportive psychotherapy provides a time, attention, and social support control that is similar to a placebo but likely to be perceived as relevant to this population.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
depressive symptoms - anhedonia subscale
Time Frame: 4 months / end of treatment
Reynolds Adolescent Depression Scale 2nd Edition - anhedonia subscale score; Scores can range from 7-28 with higher values indicating more severe anhedonia.
4 months / end of treatment
Systemic inflammation - C-reactive protein (CRP)
Time Frame: 4 months / end of treatment
C-reactive protein concentrations measured in saliva; assay detection range is approximately 25 pg/mL - 1600 pg/mL with higher values indicating the presence of more systemic inflammation.
4 months / end of treatment
reward sensitivity
Time Frame: 4 months / end of treatment
Reward motivation will be assessed behaviorally with the Effort Expenditures for Reward Task (EEfRT). The EEfRT assesses reward sensitivity by compelling participants to choose to engage in high and low effort motor tasks for varying potential monetary gains and computes reward sensitivity as the difference in propensity to choose hard choice trials at increasing trial values.
4 months / end of treatment
8. Self-reported reward sensitivity
Time Frame: 4 months / end of treatment
Self-reported reward sensitivity will be assessed using the 21-item Positive Valence System Scale (PVSS-21) which will be assessed at study enrollment, and then 4-, 8-, and 12-months after study enrollment. For each item, responses can range from 1-8, and the questionnaire is scored using a sum. Total scores can range from 21 - 189 and lower scores reflect a worse outcome.
4 months / end of treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Inflammatory gene expression
Time Frame: 4 months / end of treatment
Degree of expression of 19 pro-inflammatory genes as measured via genome-wide transcriptional profiling of RNA from peripheral blood mononuclear cells. Values are expressed as z-scores, and higher values indicate greater average expression of pro-inflammatory genes.
4 months / end of treatment

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Positive affect
Time Frame: 4-months / end of treatment
Positive and negative affect Schedule (PANAS) - positive affect subscale score; scores can range from 10 to 50 with higher values indicating more positive affect.
4-months / end of treatment
depressive symptoms - total
Time Frame: 4 months / end of treatment
Reynolds Adolescent Depression Scale 2nd Edition (RADS-2) - Total Score; Scores can range from 30-120 with higher values indicating more depressive symptoms.
4 months / end of treatment
