What is the purpose of this trial?

This trial explores a new treatment called Positive Affect Treatment (PAT) to determine if it can improve mood and prevent depression in young people who have faced tough early-life experiences. PAT is a therapy designed to increase happiness and sensitivity to rewards. The study consists of two phases: in the first, participants receive PAT or are placed on a waitlist; in the second, participants receive either PAT or supportive psychotherapy. It suits adolescents aged 12-16 who have experienced two or more difficult events during childhood and are not currently dealing with major depression. As an unphased trial, this study provides a unique opportunity for participants to contribute to innovative research that could lead to new therapeutic approaches for young people.

Will I have to stop taking my current medications?

The trial requires that you are not currently taking an antidepressant or any medications that affect immune functioning daily, like certain asthma or allergy medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that Positive Affect Treatment (PAT) is generally easy for patients to handle. Studies have found that PAT increases positive feelings and decreases symptoms of depression and anxiety after six months. Importantly, these studies have reported no major negative side effects. PAT boosts mood by improving how people respond to rewards, and it appears to do this safely. While researchers are still collecting complete safety information, current evidence suggests that PAT is safe for use. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Most treatments for depression, like antidepressant medications and traditional talk therapies, aim to reduce symptoms by addressing negative thoughts and feelings. However, Positive Affect Treatment (PAT) is unique because it focuses on enhancing reward motivation and sensitivity at neural, behavioral, and emotional levels. This cognitive-behavioral therapy approach is designed to boost positive emotions and improve reward sensitivity, potentially offering faster and more engaging results for patients. Researchers are excited about PAT because it leverages telehealth for weekly sessions, making it more accessible and convenient for participants. This novel focus on positive emotions and the use of telehealth could provide a fresh way to tackle depression, distinct from existing therapies.

What evidence suggests that Positive Affect Treatment could be effective for depression?

Research shows that Positive Affect Treatment (PAT), one of the treatments in this trial, can help with depression, anxiety, and stress. Studies have found that PAT increases positive feelings and decreases negative ones, leading to less severe depression and anxiety. Participants who have tried PAT often report improved mood and fewer suicidal thoughts. Evidence also suggests that PAT enhances awareness of rewards, boosting motivation and happiness. Overall, PAT has effectively increased positive emotions and reduced symptoms of depression. Participants in this trial may receive PAT, while others may be assigned to supportive psychotherapy or a waitlist group. ^{1 3 4 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Positive Affect Treatment

Trial Overview

The study tests Positive Affect Treatment (PAT) on these youths, comparing a group receiving PAT with a waitlist control group. The goal is to see if PAT can boost positive feelings and reduce symptoms of depression over time.

How Is the Trial Designed?

Group I: Positive affect treatment Experimental Treatment 1 Intervention

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.

Group II: Supportive Psychotherapy (SUP) Active Control 1 Intervention

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.

Group III: Waitlist Active Control 1 Intervention

Published Research Related to This Trial

In two studies involving 737 participants, individuals who fear happiness perceived positive affect treatments as a poor fit for their needs, despite these treatments being designed to help them.

This suggests that people who avoid positivity may resist treatments that could be effective for them, highlighting the importance of understanding patient preferences in therapy selection.

A pilot study involving 29 individuals with anxiety and depression showed that a 10-session positive activity intervention (PAI) significantly improved positive affect and psychological well-being compared to a waitlist group.

The PAI not only enhanced positive emotions but also led to substantial reductions in negative affect and symptoms of anxiety and depression, with these improvements lasting for at least 6 months after treatment.

The Positive Affect Stimulation and Sustainment (PASS) Module showed a moderate effect in reducing depressive symptoms among 27 female college students with dysphoric symptoms, indicating its potential as a treatment approach.

Participants in the PASS group experienced a significant increase in positive affect after sessions, while the control group showed a decrease, suggesting that PASS effectively enhances positive emotional states during treatment.

In a study involving 49 patients with major depressive disorder, positive Cognitive Behavior Therapy (P-CBT) led to significantly greater improvements in depressive symptoms compared to traditional CBT (T-CBT) during the second treatment block, indicating its enhanced efficacy.

P-CBT not only improved depressive symptoms but also resulted in higher rates of clinically significant changes in negative affect and happiness, with effect sizes indicating a strong positive impact on overall mental health, bringing participants' positive emotions to normative levels.

This study will evaluate the effectiveness of different components of Internet-based interventions for depression, involving 192 participants in a randomized controlled trial to determine the contributions of positive psychotherapeutic strategies (PPs) and behavioral activation (BA).

The trial aims to assess not only the reduction of negative symptoms but also the enhancement of positive affect and well-being, which are crucial for effective depression treatment, with follow-ups extending up to 12 months.

Greater moment-to-moment persistence of positive affect (PA) in daily life is linked to a lower likelihood of depressive symptoms in the future, as shown in a study with 540 participants from the general population.

Patients with recurrent depression who exhibit higher PA persistence are more likely to respond positively to treatment, especially when receiving antidepressants like imipramine, indicating that enhancing PA may be crucial for effective depression recovery.

Positive psychotherapy (PPT) focuses on enhancing positive emotions and engagement rather than just reducing depressive symptoms, showing significant long-term benefits, including a decrease in mild-to-moderate depression levels for up to a year in group settings.

In individual treatments for major depressive disorder, PPT resulted in higher remission rates compared to standard treatments and those combined with medication, suggesting it can be an effective supplement to traditional depression therapies.

The Clinical Positive Affect Scale (CPAS) was developed and validated as a 16-item self-report tool to measure self-perceived positive affect in a sample of 300 college students, demonstrating high internal consistency (α = 0.97).

The CPAS effectively captures positive affect and shows good validity, as it correlates negatively with measures of depression, anxiety, and drug abuse, indicating its potential usefulness for clinicians and researchers in assessing patients' emotional well-being.
