Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Perceived emotional distress intolerance is a transdiagnostic marker of psychopathology associated with psychological and interpersonal dysfunction, and the development of interventions for perceived emotional distress intolerance is of prime importance. One potential intervention is a behavioural experiment, i.e. a cognitive behaviour therapy technique where clients undergo an exercise designed to test a maladaptive belief, e.g., that negative emotions are unbearable, and adjust their belief to accommodate any disconfirmatory information that arises through the exercise. This study examines the effects of a one-session self-compassion writing behavioural experiment compared to a one-session expressive writing behavioural experiment on low perceived distress tolerance. Participants were recruited from the University of Waterloo and Prolific, and were randomly assigned to the self-compassion condition, expressive writing condition, or a control condition.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study consisted of two online surveys. During the first survey, participants answered a set of questionnaires. Then, they were prompted to think of an upsetting situation and the associated unpleasant emotions, and they were then randomly assigned to a brief self-compassionate writing, expressive writing, or neutral writing task. They then answered a series of questionnaires immediately after completing the writing task. During the second survey, one week later, participants answered a brief set of questionnaires.

RANDOMIZED

Intervention Model

PARALLEL

1/3 of the study participants (43 from UWaterloo, 98 from Prolific) were placed into the self-compassionate writing intervention group, 1/3 of the study participants (42 from UWaterloo, 100 from Prolific) were placed into the expressive writing intervention group, and 1/3 of the study participants (41 from UWaterloo, 100 from Prolific) were placed into the control group.

SINGLE

Participants
The participant did not know prior to their study participation that there are three different study conditions, and they did not find out which condition they were randomized to until the end of their study participation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Self-compassionate writing intervention

Participants assigned to this intervention were asked to engage in one brief online self-compassionate writing session, where they were asked to write about and experience their feelings from the perspective of an inner compassionate observer.

Expressive writing intervention

Participants assigned to this intervention were asked to engage in one brief online expressive writing session, where they were asked to explore their deepest thoughts and emotions surrounding an upsetting situation through writing.
