Brief joy and compassion writing exercises fail to buffer aggression after provocation

A randomized experimental study of 148 university students has found that brief writing exercises designed to induce joy or compassion did not protect against anger, negative affect, or behavioral aggression after a standardized provocation. The study, published in Borderline Personality Disorder and Emotion Dysregulation, tested whether positive psychology interventions could serve as antidotes to aggression, a question of interest because aggression is a key factor in various mental health problems, including personality disorders.

Participants were randomly assigned to one of three conditions: a joy-based writing intervention, a compassion-based writing intervention, or a procedural control. After completing the writing task, they were provoked in two ways. First, they were given unsolvable anagrams, and second, they received a standardized provocation from a condescending confederate. The researchers then measured how anger, positive affect, and negative affect changed across the session.

Measures of anger, positive affect, and negative affect were collected at three points: baseline, after the intervention, and after the provocation.

When baseline levels were controlled for, neither the joy nor the compassion condition significantly buffered against the increases in anger and negative affect, the decrease in positive affect, or the rise in behavioral aggression observed after provocation, compared with the control condition. In other words, the interventions did not prevent the typical affective and behavioral response to being provoked.

However, the study did find meaningful differences in how affect evolved over time depending on which condition participants had been assigned to. Immediately after the writing task, participants in the joy condition reported significantly higher positive affect than those in the control condition, and significantly lower negative affect than participants in both the compassion and control conditions. At that moment, the joy induction appeared to produce the most favorable emotional state.

That advantage did not last. Once participants were provoked, positive affect dropped and negative affect rose significantly more sharply in the joy condition than in the other conditions. The authors suggest this pattern may illustrate an affective contrast effect, in which a temporarily elevated mood makes a subsequent negative event feel more pronounced by comparison.

The study also examined whether trait prevention focus, described as a self-regulation style focused on avoiding negative outcomes, influenced the effects of the interventions. Prevention focus did not moderate any of the outcomes, meaning that this individual difference did not change how participants responded to the joy or compassion exercises or to the provocation itself.

The authors conclude that these findings suggest brief joy and compassion interventions do not buffer against aggression. Compared with inducing compassion, inducing joy does lead to more immediate improved affect, but this impact appears to be only short-lived. They note that more research is needed to explore the timing of such interventions, the role of contrast effects, and the longer-term mood effects of prosocial interventions as potential antidotes to aggression.

Several features of the study are important for interpreting the results. The sample consisted of university students rather than a clinical population, and the interventions were brief single-session writing tasks rather than extended training. The provocation was standardized and laboratory-based, and the peer-reviewed, accepted version of the article was shared early with a permanent DOI, with the final version of record to follow. Within these limits, the study offers a cautionary note for the idea that short positive emotion inductions can reliably protect against anger and aggression in the moment of provocation.

Subject of Research: An experimental study testing whether joy- and compassion-based writing interventions buffer against anger, negative affect, and behavioral aggression after provocation in university students.
