Evaluating and Predicting Response to a Single Session Intervention for Self-Dislike

Study Overview
=================
Brief Summary
-----------------
The investigators are testing whether a single session online intervention for self-dislike decreases: Fear of self-compassion from immediate pre to immediate post intervention Self-hatred immediate pre to 1 month post-intervention Individual depression symptoms immediate pre to 1 month post-intervention more than a placebo online single session intervention encouraging the disclosure of feelings in college students. The investigators will also explicitly test whether the following variables are predictors, of at least the smallest variance predicted of interest, of response to treatment vs. placebo on self-hatred: Pre intervention self-hatred score Screening positive for clinical depression based on self-report Immediate pre to post-intervention reduction in fear of self-compassion The investigators will also assess whether any of the variance shared between the treatment and changes in individual depression symptoms immediately pre Intervention to 1 month post-intervention is statistically mediated by change in self-hatred from immediate pre intervention to 1 month post intervention

Eligibility Criteria
-----------------
Inclusion Criteria: Participant is a current college student at the time of study enrollment Participant has not previously taken part in the study Participant speaks English well enough to complete online intervention activities, which are available in English only Participant is comfortable with completing online surveys and programs Participant is at least 18 years of age. Exclusion Criteria: The investigators will exclude participants 3 SDs above/below the mean completion time for the study or exit the study prior to randomization for our listed analyses. The investigators will also test whether there's any association between how quickly participants are responding to questions and the variability in their responses. If there is a response time frame (i.e., a series of questions that require answers where timing is measured) where there is a linear relationship between response time and response variability, the investigators may exclude those participants, as response time and response variability should be uncorrelated and a linear association can indicate random responding. This time frame can be identified visually on a graph, and sensitivity tests can be conducted to determine if slight variations on the visual interpretation affect substantive results. The investigators will exclude participants who respond with either copy/pasted responses from text earlier in the intervention (e.g. Copy and pasting only text from a previous testimonial slide) to any of free response questions. The investigators will exclude for primary analyses (but may run sensitivity analyses including them) any participants who provide responses of 5 words or fewer to writing prompts that ask for at least 1 sentence or more.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Fear of Self-Compassion by Condition | Self-report average score from the fear of self-compassion scale. Participants rate 15 items on a scale reflecting different fears/barriers to being self-compassionate they experience. Average scores range from 1-5. Higher scores indicate a greater fear of self-compassion. | Immediate pre intervention to 0-2 minute follow up post-intervention | 
| Change in Self-Hatred by Condition | Self-report average score from the self-hatred scale. Participants rate 7 items on a scale reflecting their levels of self-dislike/self-hatred. Average scores range from 1-7. Higher scores indicate a greater self-hatred. | Immediate pre intervention to one month follow-up | 
| Change in Individual Depressive Symptoms by Condition | Self-report average score from the individual symptoms on the IDAS-II Dysphoria scale. Participants rate 10 items on a scale reflecting their experience of depression symptoms that all load onto one latent factor. Average scores range from 1-5. Higher scores indicate experiencing more of a given symptom. | Immediate pre intervention to one month follow-up | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Verbally Expressed Emotion-Sadness | Self-report average score of verbally expressed emotion-sadness scale. Participants rate 3 items reflecting their willingness to disclose sadness to others. Average scores range from 1-4. Higher scores indicate less willingness to disclose sadness to others. | Immediate pre intervention to 0-2 minute follow up post-intervention | 
| Change in PHQ-9 Depression Symptoms | Self-report average score of depression symptoms on the PHQ-9 scale. Participants rate 9 items related to depression symptoms they've experienced in the past two weeks. Average scores range from 0-3. Higher scores indicate more depression symptoms | Immediate pre intervention to one month follow-up | 
| Change in the Self-Dislike Item of the BDI-II Depression Symptom | Self-report score of the BDI II Self-Dislike item. Participants rate 1 item related to self-dislike on a scale from 0-3. A higher score indicates more self-dislike. | Immediate pre intervention to one month follow-up | 
| Change in Drinking to Cope Scale | Self-report average score of the Drinking to Cope scale. Participants rate 5 items on how often they drink alcohol to cope with difficulties. Average scores range from 1-5. Higher scores indicate greater frequency in drinking to cope. | Immediate pre intervention to one month follow-up | 
| Change in Social Phobia Screener | Self-report average score of the Social Phobia Screener scale. Participants rate 5 items on how socially anxious they have been in the previous month. Average scores range from 0-4. Higher scores indicate more social anxiety | Immediate pre intervention to one month follow-up |
