“…The intervention did not have a generalized effect. However, the effect sizes' 95% confidence intervals (see Table 2) were compatible with a large effect similar to the one found in Castillo-Eito et al (2020). The intervals were quite large, indicating that the study was underpowered to detect the effect.…”

“…A power analysis was conducted using the effect size for action planning reported by Castillo-Eito et al (2020), which was d = 1.00. This power analysis indicated that a total sample size of 43 participants was needed to reach a power of 0.80 with an alpha of 0.05.…”

“…Although reviews and meta-analyses have consistently found that interventions are more effective when addressed to those adolescents with a higher risk of behaving aggressively (Castillo-Eito et al, 2020;Cox et al, 2016), intervention programs have had mixed effectiveness (Castillo-Eito et al, 2020;Gaffney et al, 2019). A recent metaanalysis attempted to identify the active ingredients of effective interventions and found that action planning was the behaviour change technique that was frequent in effective interventions that reduced aggression among at-risk adolescents (Castillo-Eito et al, 2020). Action planning is defined as "detailed planning of performance of the behaviour" (Michie et al, 2014, p. 260).…”

“…However, this technique is often used along with other techniques. In fact, all the interventions reviewed by Castillo-Eito et al (2020) contained additional techniques. In the current study, we aim to determine whether this technique on its own is effective to reduce anger and aggression among adolescents.…”

Background: Interventions that include action planning are more effective than others to reduce aggression among at-risk adolescents. However, they often include other behaviour change techniques. The efficiency of interventions could be improved if action planning on its own could reduce aggression. The current study investigates the effect of a volitional help sheet (VHS) that prompts the creation of action plans to manage anger in response to specific or generic anger triggers. It was hypothesised that participants completing the VHS would have lower levels of aggression and anger at follow-up. The moderation effects of violent intentions, callous-unemotional traits and negative urgency were also tested.Methods: One hundred adolescents (10-17 years old) with behavioural problems were recruited and randomised to three conditions: specific anger triggers, generic anger trigger or active control. An active control group was used to blind participants and teachers to group allocation. Self-reported data on anger and aggression was collected at baseline, one month and six months after intervention at the participants’ schools. This trial was registered at www.clinicaltrials.gov (identification number NCT03693209).Results: Eighty-one participants completed at least one follow-up and were included in the analysis. Neither VHS had a significant effect on anger or aggression overall, but moderator effects were found; both VHS were effective for participants with high callous-unemotional traits and low negative urgency. There were no differences between specific and generic triggers.Conclusions: Adolescents with high callous-unemotional traits have traditionally been seen as a difficult population to treat. The VHS is a cost-effective technique to reduce aggression in this population which is easy to implement. Future studies are needed to identify which behaviour change techniques are needed for other groups.

“…Innumerable attempts have been made in order to reduce aggression in adolescents ( Castillo-Eito et al, 2020 ). School-based physical activity interventions are practical, effective, and universally applicable ( Kriemler et al, 2011 ; Rodríguez et al, 2016 ).…”

Reducing Aggression and Improving Physical Fitness in Adolescents Through an After-School Volleyball Program

This study aimed to determine the effects of an after-school volleyball program on aggression and physical fitness in 14–16 years old students. One hundred and seven participants were randomized to a small-sided volleyball (SSV) training group or a control group (CON). The SSV group completed 8 months of small-sided volleyball training twice a week after school in addition to the regular physical education classes. Yo-Yo Intermittent Recovery Level 1 test (YYIRT1), medicine ball throw (MED), vertical jump (VJ), and Buss and Perry’s aggression questionnaire were evaluated before and after 8 months of training. Results revealed a significant interaction effect (group × time) in total sample for physical aggression [ F (1, 105) = 17.688; p < 0.001], verbal aggression [ F (1, 105) = 4.973; p = 0.028], anger [ F (1, 105) = 7.662; p = 0.007], medicine ball throw [ F (1, 105) = 36.143; p < 0.001], and YYIRT1 [ F (1, 105) = 12.508; p = 0.001]. After-school small-sided volleyball for adolescents was accompanied by a significant decrease in aggression compared to physical education classes only. Additionally, adolescents from SSV group showed better results in physical fitness compared to the control group. Our findings significantly contribute to the understanding of possible mechanisms for reducing adolescents’ aggression, which include enjoyment, motivation, and self-control through sport intervention.

Effects of Christian REACH forgiveness intervention to reduce aggressiveness in adolescents with conduct disorder

While there have been significant advances in the treatment of conduct disorder (CD), there is still a need to seek and develop therapeutic solutions that can overcome the poor long‐term prognosis. In this evidence‐based research, we evaluated the effect of immediate REACH Forgiveness training on the severity of aggressiveness among adolescents with CD. The purposive sample consisted of 32 Catholics aged 15–18 randomly placed in an experimental or nonintervention control group. Participants in the experimental group were subjected to an immediate REACH Forgiveness session for Christians, which lasted 6 h, while participants in the control group played board games and spent time together in the day care center during this time. The scores obtained by adolescents in the experimental group regarding forgiveness (decisional and emotional) and aggressiveness (anger, physical aggression, verbal aggression, and hostility) improved under REACH Forgiveness training, and these positive effects were still evident 1 month after the intervention (while the control scores did not change in a statistically significant way). The data obtained indicate that the Christian version of REACH can provide important support for other forms of psychopedagogical therapy in adolescent Catholics with CD in reducing aggressive behavior.
