Understanding and Intervening With State Shame and Self-criticism
Canada348 participantsStarted 2023-10-17
Plain-language summary
The goal of this clinical trial is to compare the momentary effects of a one-session intervention (compassion-based, logic-based, or placebo control) on individuals with high or low trait self-criticism. The main questions it aims to answer are:
After a momentary shame induction, will a compassion-based intervention and a logic-based intervention both be more beneficial than a placebo control condition in terms of therapeutic outcomes?
Will the compassion-based intervention most effectively increase soothing affect, state self-compassion, and state self-reassurance?
Will the effects of these two interventions (1) differ as a function of the individual's trait self-criticism, and (2) will this be due to differing indirect effects of the intervention on safe/soothed feelings based on trait self-criticism?
Participants will first complete a set of baseline measures. Two to seven days later, they will be randomly assigned to one of three study conditions (i.e., compassion-based, logic-based, placebo control) after a brief shame induction. Participants will be asked to complete a set of questionnaires both before and after the shame induction as well as post-intervention.
This research will help us understand how best to intervene with the shame and self-criticism.

Exclusion criteria
✕. Any duplicate survey completions from the same participant for the same study survey, as indicated by their embedded ID code in their Qualtrics data, will be excluded from analysis. For Part 1, the most complete survey completion for each participant will be retained. For Part 2, the most complete survey completion for each participant will also be retained unless the participant has begun the shame induction exercise. If a participant in Part 2 has begun the shame induction and then completes another submission, they will be excluded.
✕. Participants who do not complete Part 1 measures required for primary hypotheses will also be excluded from analyses (specifically, participants who do not complete the measures of trait self-criticism and trait self-compassion).
✕. Participants who complete Part 1 but are not randomized to a condition in Part 2, will be excluded from analyses related to Part 2 variables. We will run ANOVAs and/or non-parametric Kruskal Wallis tests with continuous baseline data as the DVs to test if there are any significant differences between participants who do Part 2 and those who do not. We will also run Fisher-Freeman-Halton exact tests on categorical baseline data to test if there are any significant differences between participants who do Part 2 and those who do not.
✕. Participants who respond to several scales within the same survey with overly consistent responses (i.e., appear to click the same response for every scale item, even though some are reverse scored, assessed via testing of scale variances) may be excluded from analyses involving that survey. Their data from other surveys will still be retained for other analyses.
What they're measuring
1
State Shame and Guilt Scale (shame subscale)
Timeframe: Immediately pre-shame induction, immediately after the shame induction, immediately after the intervention
2
Momentary self-criticism
Timeframe: Immediately pre-shame induction, immediately after the shame induction, immediately after the intervention
3
Self-Assessment Manikin (Arousal and Pleasure subscales only)
Timeframe: Immediately pre-shame induction, immediately after the shame induction, immediately after the intervention
. Participants who complete a survey in an unreasonably short or long amount of time compared to the average participant may be excluded from analyses involving that survey. Their data from other surveys will still be retained for other analyses.
✕. Participants who fail half or more of the attention checks in Part 1, and the first attention check prior to randomization in Part 2 will be excluded from the data.
✕. Participants who were ineligible or withdrew consent will also be excluded from the data.
✕. Prolific participants who could not complete the Captcha Verification question or fail one or both of the two bot check questions will also be excluded from the analyses.
