Claim 1 of 3Not coveredA 2024 meta-analytic review found little evidence that venting helps reduce anger, and in some cases it could increase anger.View evidenceHide evidence

As stated154 studies; 10,189 participants

Why this verdict

The abstract-level profile supports the main headline idea that arousal-increasing activities such as venting are not effective overall for reducing anger/aggression (g = -0.02, 95% CI [-0.13, 0.09]) and states that the findings do not support venting anger as an anger-management strategy. However, the added claim that venting could increase anger in some cases is not directly established in the supplied abstract profile; the abstract only says these effects were heterogeneous and complex. At this evidence depth, the 'could increase anger' component is not verifiable.

“In contrast, arousal-increasing activities were ineffective overall (g = -0.02, [-0.13, 0.09]) and were heterogenous and complex.”
Claim 2 of 3Not coveredThe authors say reducing physiological arousal is the key to curbing anger, and that calming activities such as slow-flow yoga, mindfulness, progressive muscle relaxation, diaphragmatic breathing, and taking a timeout reduced anger, whereas arousal-boosting activities usually did not.View evidenceHide evidence

Why this verdict

The abstract-level profile supports the broad contrast: arousal-decreasing activities reduced anger/aggression, while arousal-increasing activities were ineffective overall. It also names examples such as deep breathing, mindfulness/meditation, and venting/jogging/cycling. But several specific activities in the story—slow-flow yoga, progressive muscle relaxation, diaphragmatic breathing as distinct from deep breathing, and taking a timeout—are not specifically verifiable from the supplied abstract profile. The broad arousal-reduction framing is supported, but the full activity list is not verifiable at abstract depth.

As stated154 studies; 10,189 participants

Why this verdict

The paper profile reports a meta-analytic review based on 154 studies, 184 independent samples, and 10,189 participants. The abstract-level moderator/generalizability material also reports analyses across genders, races, ages, and cultures, which is consistent with the story’s description of a broad participant range.

Context layer

What the story left out

Important study details the story did not include.

  • The paper reports broad moderator/generalizability findings for arousal-decreasing activities across time, demographics, populations, delivery modes, session formats, and settings.

    The story mentions a broad range of participant characteristics, but it does not clearly convey the paper’s more specific claim that arousal-decreasing effects were stable or effective across these subgroups, delivery modes, and settings.

    From Meta-analysis with moderator/subgroup analyses

  • Important abstract-depth limitations include lack of detailed heterogeneity statistics, risk-of-bias information, publication-bias analyses, subgroup-specific effect estimates, and full moderator-analysis details in the supplied evidence.

    The story caveats mention that more research is needed and that the work is a meta-analytic review, but they do not address these methodological-detail limitations visible in the supplied abstract-level profile. These omissions matter especially for judging subset claims such as whether particular venting or exercise activities can increase anger.

4 things the story did carry across
  • The review was a meta-analysis of 154 studies, 184 independent samples, and 10,189 participants.
  • Arousal-decreasing activities reduced anger and aggression in the pooled analysis, with a reported effect size of g = -0.63, 95% CI [-0.82, -0.43].
  • Arousal-increasing activities, including venting-like or exercise-like activities, were ineffective overall for reducing anger/aggression, with g = -0.02, 95% CI [-0.13, 0.09].
  • The abstract describes arousal-increasing activity effects as heterogeneous and complex.

study summary

Lead result

1Lead resultsecondary dataQuantitatively synthesize the effects of arousal-decreasing anger management activities (e.g., deep breathing, mindfulness/meditation) on anger and aggression outcomes.Meta-analysisExpand

In plain English

Meta-analytic synthesis (154 studies, 184 independent samples, N = 10,189) found that arousal-decreasing anger-management activities (e.g., deep breathing, mindfulness/meditation) produced a moderate-to-large reduction in anger and aggression (Hedges' g = -0.63, 95% CI [-0.82, -0.43]). The abstract reports these effects as robust and consistent across demographic groups, clinical/legal status, delivery modes, session formats, and settings.

Key findings

  • Arousal-decreasing activities (examples: deep breathing, mindfulness, meditation) decreased anger and aggression in the pooled meta-analysis.g = -0.63 (95% CI [-0.82, -0.43])
“This meta-analytic review, based on 154 studies including 184 independent samples involving 10,189 participants, tested the effectiveness of both types of activities.”

In plain English

Meta-analytic synthesis reporting that arousal-increasing activities (e.g., hitting a bag, jogging, cycling / 'venting') were ineffective overall for reducing anger and aggression (Hedges' g = -0.02, 95% CI [-0.13, 0.09]); the effects were described as heterogeneous and complex in the abstract.

Key findings

  • Arousal-increasing activities were ineffective overall for anger and aggression outcomes.g = -0.02, 95% CI [-0.13, 0.09]
“In contrast, arousal-increasing activities were ineffective overall (g = -0.02, [-0.13, 0.09]) and were heterogenous and complex.”
What this piece can’t prove
  • The abstract presents pooled results but does not provide the number of studies/samples that contributed specifically to the arousal-increasing activity estimate.

In plain English

The meta-analysis reports that arousal-decreasing activities reduced anger and aggression (g = -0.63, 95% CI [-0.82, -0.43]) and that these effects were robust and generalizable across time, demographic groups (gender, race, age, culture), participant populations (students vs non-students; offenders vs non-offenders; with vs without intellectual disabilities), and implementation modalities (digital platforms vs researcher/therapist delivery; group vs individual sessions; field vs laboratory settings).

Key findings

  • Arousal-decreasing activities reduced anger and aggression in the pooled analysis.g = -0.63, 95% CI [-0.82, -0.43]
  • Effects of arousal-decreasing activities were reported as stable over time and across demographic groups (gender, race, age, culture).
“Effects were stable over time for participants of different genders, races, ages, and cultures.”
What this piece can’t prove
  • Abstract does not report subgroup- or moderator-specific effect sizes, confidence intervals, p-values, heterogeneity (e.g., I²) within subgroups, or the number of studies/samples contributing to each subgroup analysis.
  • Abstract does not describe statistical details of moderator analyses (e.g., meta-regression coefficients, covariates, modeling approach, handling of multiple comparisons).
  • Abstract does not report potential limitations such as residual heterogeneity, risk of bias across included studies, or publication bias assessments specific to subgroup analyses.
