Investigating the relationship between sleep quality and parental bonding patterns with aggression among adolescents in the City of Bushehr

Aggression is a prevalent issue among adolescents and is associated with a variety of problems. The present study aimed to investigate the relationship between sleep quality and parental bonding patterns on the one hand with aggression on the other hand among adolescents in the city of Bushehr. In this cross-sectional study, 851 adolescent students were selected using proportionate simple random sampling from all high schools. Data collection instruments were a demographic information form and three questionnaires: the Pittsburgh Sleep Quality, the Parental Bonding, and the Aggression Scales. Multiple linear regression was used for data analysis. The participants' mean sleep quality score was 7.94 ± 3.84. The mean scores for parental bonding patterns of care and overprotection were 24.62 ± 6.32 and 17.23 ± 6.14, respectively. The mean total aggression score was 82.76 ± 17.37. Multiple linear regression model showed a significant positive association between total aggression and poor sleep quality among adolescents (sβ = 0.160, P = 0.003). In addition, the subjects' inclination to use a digital device instead of sleeping positively associated with their total mean aggression scores, as measured both for three to four nights per week (sβ = 0.150, P = 0.001) and for more than four nights per week (sβ = 0.255, P < 0.001). Conversely, a significant negative association was found between total aggression score and parental bonding patterns, characterized by care (sβ = - 0.235, P < 0.001). In the final multiple linear regression model Sleep quality, digital device use, and parental bonding were identified as key predictors of total aggression. the results highlighted the potential value of interventions promoting healthy lifestyles, sleep hygiene, guidelines for digital device use, and appropriate parent-adolescent relationship patterns in school-based aggression prevention programs.
