Enhanced Cognitive Reappraisal and Emotion Awareness Training (eCREAT) for Maladaptive Anger Inhibition - A Pilot Study

Enhanced Cognitive Reappraisal and Emotion Awareness Training (eCREAT) for Maladaptive Anger Inhibition - A Pilot Study

Habitual suppression of intense anger, commonly known as maladaptive anger inhibition, is a widespread issue related to various adverse outcomes. These include, for instance, diminished social support, reduced relationship quality, increased risk for coronary heart disease, and heightened susceptibility to chronic and temporary pain conditions. Developing effective psychological treatments may be one key approach to alleviate the distress experienced amongst these individuals.

The overall goal of this pilot study is to further develop and enhance a previously evaluated treatment protocol for maladaptive anger (Bjureberg et al., 2023) to more effectively target maladaptive anger inhibition. The specific goals are:

1. To assess the feasibility and acceptability of the study (operationalized as number of completed modules and measurements, reported negative events and patient experience).

2. To assess outcome variability and estimate the relative effect of the treatment in reducing maladaptive anger inhibition. Maladaptive anger inhibition was operationalized as high levels of trait anger suppression (main outcome), anger rumination (secondary outcome) as well as low levels assertive expression of anger (secondary outcome).

   Secondary aims (to be reported in secondary papers)

3. To assess and explore participants' qualitative experiences of maladaptive anger inhibition.

4. To explore within-subjects emotion dynamics using daily assessments.

1. Treatment feasibility and acceptability will be assessed by measuring treatment retention and adherence (operationalized as number of drop-outs, completed modules, homework assignments, and assessments), treatment credibility and satisfaction (using questionnaires), number of reported adverse events and patient experiences following treatment (see below for details).
2. Following the intention to treat principle data will be analyzed using all participants that were included in the treatment. Preliminary treatment efficacy will be determined by assessing the phase effect of the treatment for each respective outcome (trait anger suppression, anger rumination, and anger assertiveness). More specifically, an interrupted time series design will be used to compare the difference in effect between the treatment phase and a prolonged baseline phase, each consisting of 4 assessments (totaling 8 measurement points). The primary phase effects will be evaluated at treatment termination. Moreover, we will also explore whether treatment effects are maintained at the 3-month follow-up.
3. A subset of 10 consenting participants will be invited to post-treatment interviews. Participants will chosen so as to ensure representation across demographic and clinical variables such as age, gender, and whether they improved or not on the main outcome (trait anger suppression). Interviews will both focus on treatment experiences (goal 1) and participants' qualitative experiences of maladaptive anger inhibition (goal 3).
4. Participants will complete two bursts of 7 days of daily measures of anger and anger regulation strategies, one burst before treatment and one after). These daily measurements will be used to explore within-subject emotion dynamics by comparing emotion dynamics before and after the treatment using dynamic structural equation modeling (DSEM) as our analytical method.

Assessment procedure:

Participants will undergo intensive assessment throughout the project. Participants will complete 1 screening assessment followed by 4 weeks of weekly baseline assessments, with one of the weeks including daily assessments (burst 1). Following the baseline phase, participants will enroll in a 4-week online treatment with weekly assessments. After treatment, participants will undergo 1 week of daily assessments (burst 2) and a 3-month follow-up.

Inclusion Criteria:

• Experience of maladaptive anger inhibition as indicated by a score on the upper quartile on the Anger Expression-In scale from State-Trait Anger Expression Inventory-2 (STAXI-2).

Exclusion Criteria:

• Risk for violence and harm to others.
• Prior convictions of violence/abuse.
• Ongoing psychological treatment.
• Change in psychotropic medication within 2 months prior to enrollment.
• Severe psychiatric disorder, such as severe depression or psychotic disorder
• Ongoing substance use.
• Life circumstances that interfere with treatment.
• Suicidal ideation.
• Not able to read and write in Swedish or learning difficulties (the treatment-format requires normal literacy skills).
