The efficacy of spiritual intelligence training on school vandalism and aggression in adolescent students

Aggression and vandalistic behaviors are among the most common behaviors caused by psychological trauma in teenagers, and it is necessary to use psychological interventions to reduce the tendency to aggression and vandalistic behaviors. One of these interventions that has not been investigated in this field so far is the training of spiritual intelligence.

The aim of the present study was to determine the effectiveness of spiritual intelligence training on school vandalism and student aggression.

The research design was a semi-experimental type of pre-test, post-test with control group. The statistical population included all 2195 10th grade female students who were studying in the secondary schools of Birjand city in the academic year of 2021-2022. The sample of the research was considered to be 25 people for each group, who were selected using direct sampling and then assigned to two groups, the test and the control, by a simple random method. The experimental group underwent spiritual intelligence training for 8 sessions (Mansoori & Hosseini, 2019). Aggression questionnaire (Zahdifar et al., 2000) and school vandalism questionnaire (SalesMoayyed, 2017) were used in the pre-test and post-test stages and multivariate covariance analysis test in SPSS-26 software was used for data analysis.

The findings show that spiritual intelligence training on all components of aggression including anger and rage (F= 198.844; P< 0.001), aggression and insult (F= 96.515; P< 0.001) and stubbornness and resentment Tuzi (F= 146.664; P> 0.001) and intra-school vandalism (F= 156.430; P> 0.001) and extra-school vandalism (F= 151.162; P> 0.001) Adolescent girls are affected.
