The goal of this clinical trial is to learn whether an single session intervention can reduce psychological impairment in adult individuals with moderate depression. The main questions it aims to answer are: Is this evidence-based intervention acceptable to study participants? Is this evidence-based intervention feasible to implement in a single session? Is there evidence that the evidence-based intervention reduces psychological impairment in adults with moderate to severe depression? Participants will complete: * an in-depth diagnostic screening interview prior to enrollment * a set of mental health questionnaires at baseline and two weeks post-intervention * a 3-hour, evidence-based, single session psychotherapeutic intervention with a trained clinician

CARED Treatment Experience Survey
A brief survey which probes the qualitative experience of participants during the intervention (i.e., tolerability, their level of engagement, satisfaction with treatment). Participants respond to eight items, rated on a 4-point Likert scale (1 - Not at all to 4 - Completely) to indicate their level of agreement with each item. Higher scores on the measure indicate greater tolerability, satisfaction, and endorsement of treatment. Total possible scores range from 8 to 32.
Time frame: Immediately post-intervention (same day)
Change from baseline on Behavioral Activation Scale at two weeks post-intervention
The Behavioral Activation Scale is a measure which assesses participant current levels of behavioral activation in the context of current depression. Participants respond to twenty-five items, rated on a 7-point Likert scale (0 - Not at all to 6 - Completely) to indicate their activation levels during the past week. Higher scores on the measure indicate greater activation (i.e., higher functioning) and lower scales indicate lower activation. Total possible scores range from 0 to 150.
Time frame: Baseline and Two Weeks post-intervention
Change in baseline Repetitive Thinking Questionnaire - 10 item form to two weeks post-intervention
The Repetitive Thinking Questionnaire- 10 item form is a well-validated measure that assesses trait-like repetitive negative thinking (e.g., worry, cognitive rumination) during times of distress. Participants respond to ten items, rated on a 5-point Likert scale (1 - Not true at all to 5 - Very True) to indicate to what extent they agree with each statement. Higher scores on the measure indicate greater trait engagement in repetitive negative thinking. Total possible scores range from 10 to 50.
Time frame: Baseline and Two weeks post-intervention
Change from baseline on Snaith-Hamilton Pleasure Scale at two weeks post-intervention
The Snaith-Hamilton Pleasure Scale is a measure which assesses participant capacity to experience pleasure in the past few days. Participants respond to fourteen items, rated on a 4-point Likert scale (0 - Strongly disagree to 4 - Strongly agree) to indicate their hedonic capacity over the last few days. Higher scores on the measure indicate greater hedonic capacity, or capacity to experience pleasure. Total possible scores range from 0 to 56.
Time frame: Baseline and Two weeks post-intervention
Change from baseline on Behavioral Inhibition and Behavioral Activation Scale - Inhibition Subscale at two weeks post-intervention
The Behavioral Inhibition and Behavioral Activation Scale- Inhibition subscale is a well-validated measure that assesses for trait-like behavioral inhibition, similar to overcontrol. Participants respond to seven items, rated on a 4-point Likert scale (1 - Very true for me to 4 - Very false for me) to indicate their general behavioral inhibition. Higher scores on the measure indicate higher inhibition. Total possible scores range from 7 to 28.
Time frame: Baseline and Two weeks post-intervention
Change from baseline on Behavioral Inhibition and Behavioral Activation Scale - Activation Drive Subscale at two weeks post-intervention
The Behavioral Inhibition and Behavioral Activation Scale- Activation Drive subscale is a well-validated measure that assesses for trait-like behavioral drive, similar to goal seeking activation. Participants respond to four items, rated on a 4-point Likert scale (1 - Very true for me to 4 - Very false for me) to indicate their general behavioral drive. Higher scores on the measure indicate higher drive/goal seeking. Total possible scores range from 4 to 16.
Time frame: Baseline and Two weeks post-intervention
Change from baseline on Behavioral Inhibition and Behavioral Activation Scale - Activation Fun Seeking Subscale at two weeks post-intervention
The Behavioral Inhibition and Behavioral Activation Scale- Activation Fun Seeking subscale is a well-validated measure that assesses for trait-like behavioral fun seeking, similar to excitement seeking and surgency on other measures of activation. Participants respond to four items, rated on a 4-point Likert scale (1 - Very true for me to 4 - Very false for me) to indicate their general levels of fun/excitement seeking. Higher scores on the measure indicate higher fun seeking. Total possible scores range from 4 to 16.
Time frame: Baseline and Two weeks post-intervention
Change from baseline on Behavioral Inhibition and Behavioral Activation Scale - Activation Reward Responsiveness Subscale at two weeks post-intervention
The Behavioral Inhibition and Behavioral Activation Scale- Activation Reward Responsiveness subscale is a well-validated measure that assesses for trait-like behavioral sensitivity to reward. Participants respond to five items, rated on a 4-point Likert scale (1 - Very true for me to 4 - Very false for me) to indicate their general levels of reward sensitivity. Higher scores on the measure indicate higher pleasure from reward and reward seeking. Total possible scores range from 5 to 20.
Time frame: Baseline and Two weeks post-intervention
Change from baseline on Quality of Life Enjoyment and Satisfaction Questionnaire at two weeks post-intervention
The Quality of Life Enjoyment and Satisfaction Questionnaire is a measure which assesses current levels participant satisfaction in many domains of their life (e.g., social and romantic relationships, work/school, health, overall wellbeing). Participants respond to sixteen items, rated on a 5-point Likert scale (1 - Very Poor to 6 - Very Good) to indicate their levels of quality of life and life satisfaction during the past week. Higher scores on the measure indicate greater satisfaction. Total possible scores range from 16 to 80.
Time frame: Baseline and Two weeks post-intervention
Change from baseline on Dimensional Anhedonia Rating Scale at two weeks post-intervention
The Dimensional Anhedonia Rating Scale is a measure which assesses participant current levels of hedonic capacity, or ability to feel pleasure. Participants fill in two experiences that they typically enjoy across four domains (favorite sensory experiences, favorite foods, favorite social activities, favorite pastimes/hobbies) and then rate how much they would enjoy, spend time on, desire for, and interest of each domain, rated on a 5-point Likert scale (1 - Not at All to 5 - Very Much). These ratings are summed to index overall desire for, satisfaction with, and likelihood of pursuing favorite activities at the trait-level (i.e., no specific timeframe). Higher scores indicate greater hedonic capacity. Total possible scores range from 16 to 80.
Time frame: Baseline and Two weeks post-intervention
