Prevalence and factors associated with bullying phenomenon among pre-adolescents attending first-grade secondary schools of Palermo, Italy, and a comparative systematic literature review.

BACKGROUND: Bullying is recognized as one of the most significant social and health problems in the school environment for children and adolescents. In Italy, bullying involved 2 in 10 kids between 11-17 years that referred to have been bullied two or more times in a month. In Sicily, the estimated prevalence of children aged 11 to 15 that suffered at least one act of bullying in the last two months was 14% in 2011. METHODS: A questionnaire consisting of 30 items investigating physical, verbal and indirect bullying, observers of bullying, resiliency, and prosociality was administered to preadolescents of ten first-grade secondary schools within the Palermo Province in order to analyze prevalence and factors associated with bullying phenomenon. Also, a systematic literature review (SLR) analyzing manuscripts that reported prevalence of the bullying phenomenon worldwide was conducted. RESULTS: Survey: a total of 867 students, belonging to 35 s and 31 third classes of ten different schools in Palermo, Italy, were recruited in the survey. The values of physical bullying are included between the 4% of the single question method and the almost forty percent detected by the score of 7 method. Verbal bullying oscillates between 15.9% and 66.3%. Observers average values varies from 15.8% to 47.5%. SLR: the estimated prevalence showed a considerable fluctuation. The occurrence of the bullying phenomenon was low in some Northern European countries, while in Anglo-Saxon countries it affected over a quarter of the middle school student population (28% in Maryland, USA and 21% in the UK). CONCLUSIONS: The prevalence of the bullying phenomenon recorded by this survey with the three different methods used is similar to observations in international literature. In the Sicilian context, a higher prevalence of bullying phenomena was observed in pre-adolescents attending major classes and in schools with lower socio-economic index. Though it remains difficult to obtain univocal data that clarifies the prevalence of different type of bullying, the continuous investigation of prevalence and factors associated with the phenomenon is a necessary starting point to introduce interventions and preventive measures in Public Health programs.

Prevalence of the bullying phenomenon in a schools sample of Palermo, Sicily: a pre-post intervention observational study among teachers.

BACKGROUND AND AIM OF THE WORK: Bullying involves a significant percentage of school-age children. According to the latest available surveillance data, in Sicily, the estimated prevalence among 11-15 years old children is 14%. This study aimed to estimate a prevalence of the bullying phenomenon, observed by teachers, in a sample of secondary schools of Palermo, Sicily. Moreover, after the conduction of preventive interventions among teachers, aimed to evaluate any modification in bullying prevalence. METHODS: A cluster sampling selection according to socio-economic level of the school neighborhood was carried out. Two anonymous online questionnaires, pre and post-intervention, were administered to the 63 teaching staff, belonging to second and third year classes of ten secondary schools enrolled. Preventive interventions were conducted among teachers by experienced researchers. RESULTS: Prevalence of bullying reported decreased significantly from 44.4% to 19.0% (p-value 0.001), comparing pre and post-intervention questionnaires. A reduction in the prevalence of verbal and physical bullying and a concomitant slight increase of indirect bullying were also observed. All the characteristics, reported by the teaching staff, for describing bullies, victims and observers of bullying have been categorized under three different content domains (affective-relational discomfort, socio-cultural context, and character/natural disposition). CONCLUSIONS: The present study estimated the prevalence and the characteristics of bullying phenomenon in a sample of secondary schools of Palermo, evaluating the reduction of bullying episodes among students, after a preventive interventions conducted among teaching staff. Data obtained confirmed the effectiveness of this approach and suggested an extension of the project at Regional Level.
