Samoozljeđivanje i suicidalnost srednjoškolaca prije i tijekom pandemije COVID-19

high-school students when comparing 2016 (17.0%) and 2021 (29.1%). No significant differences were found in suicidal ideations, although the proportion of participants who reported thinking about committing suicide on at least one occasion was high (27.7% in 2016 and 24.8% in 2021). Adolescent girls reported roughly two times more self-injury (38.2% in 2021) and suicidal ideations (34.2%) than adolescent boys (19.9% self-injury and 15.8% suicidal ideations in 2021). Most self-injuries and suicidal thoughts were reported by young people who estimated that their families had less money than others. The results of hierarchical regression analyses showed that selected sets of predictors accounted for markedly high variance percentages of both self-injuries (43.6%) and suicidal ideations (41.9%). Significant factors for both types of self-aggressive behaviours include lower expression of parental warmth and more parental rejection, as well as non-constructive ways of coping with stress and more negative self-concept in a certain aspect
