Prevalence, characteristics, and emotional effects of school bullying among Grade 5-6 students in Hat Yai, southern Thailand: a cross-sectional study.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSchool bullying is a common form of youth violence and an adverse experience with well-established effects on mental health and development. Thailand reports one of the highest prevalence rates globally. However, evidence concerning bullying in primary school populations, particularly in the southern region of Thailand, remains limited. This study examined the prevalence and characteristics of traditional bullying and cyberbullying and identified the factors associated with bullying roles among students in Grades 5 and 6 in Hat Yai, southern Thailand.
methodsWe conducted a school-based, cross-sectional survey in one public and one private primary school. A total of 291 students participated. Data were collected using self-administered questionnaires, including the Thai versions of the Revised Olweus Bully/Victim Questionnaire, the Cyber-Aggression Perpetration/Victimization Scale, and the Patient Health Questionnaire for Adolescents. Students were classified as victims, bullies, bully-victims, and those not involved. Associated factors were identified using multinomial logistic regression and reported using relative-risk ratios (RRRs) with 95% confidence intervals (CIs).
resultsOverall, 78.7% of the participants were involved in bullying, with bully-victims constituting the largest group (44.7%), followed by victims (30.2%) and bullies (3.8%); a sensitivity analysis restricted to the two global R-OBVQ items yielded an involvement prevalence of 59.1%. Verbal bullying was the most common form of bullying, and incidents frequently occurred in unsupervised areas in the school. Moderate-to-severe depressive symptoms were strongly associated with bullying involvement, particularly with being a bully-victim. In adjusted analyses, attending a private school (RRR 4.48, 95% CI 1.97-10.22) and authoritarian parenting (RRR 4.20, 95% CI 1.24-14.21) were independently associated with a higher relative risk of being a bully-victim, whereas shorter-than-average stature was associated with a lower relative risk (RRR 0.27, 95% CI 0.08-0.93). Cyberbullying was uncommon (5.2%) and was not significantly associated with bullying roles.
conclusionsBullying involvement is highly prevalent among primary school students in southern Thailand, with bully-victims constituting the largest and the most vulnerable group in terms of mental health. These findings highlight the need to integrate mental health screening, parenting-focused interventions, and improved supervision within school environments to prevent school bullying.
