Sažetak

Research objectives: The aim of this study was
to examine the prevalence of suicidal ideation
in early adolescents and to determine its association
with biological rhythms (chronotype) and
time spent in front of screens, with an analysis
of the main effects of sex and the interaction
between sex and suicidality. Materials and methods:
A cross-sectional study was conducted on a
sample of early adolescents (non-suicidal boys n
= 145, non-suicidal girls n = 152, suicidal boys
n = 54, and suicidal girls n = 41). To assess the
prevalence of suicidal ideation, we analyzed responses
regarding thoughts about death, wish for
death, and thoughts about suicide. Standardized
questionnaires were used to assess overall chronotype
and total time spent in front of screens. Statistical analysis: Prevalence and sex differences
were tested using the chi-square test of independence.
The associations of chronotype and screen
time with suicidality and sex were analyzed using
two-way analysis of variance (ANOVA). Results:
The frequency analysis did not show statistically
significant sex differences in suicidal ideation:
frequent thoughts about death were present in
25.8% of boys and 19.5% of girls (p = 0.138), wish
for death in 6.0% of boys and 5.1% of girls (p =
0.697), while 7.1% of boys and 8.2% of girls often
thought about suicide (p = 0.672). Regarding
chronotype, it was found that adolescents with
a more pronounced evening chronotype did not
have statistically more frequent suicidal ideation
compared with those who lean toward a morning
chronotype (p = 0.233), and this finding was
stable in both sexes (p for interaction = 0.283),
although girls in general tended more toward the
evening type (p = 0.013). The key finding shows
a highly significant main effect of suicidality on
screen time (p < 0.001); suicidal boys (M = 2.49)
and girls (M = 2.63) spend considerably more
time in front of screens than their non-suicidal
peers, regardless of sex (p for interaction =
0.861). Conclusion: Early adolescents of both sexes
experience suicidal ideation to a similar extent.
While belonging to a particular chronotype does
not represent a risk for suicidality, increased time
spent in front of screens emerges as a universal
and very strong marker of suicidal crisis in both
sexes, pointing to the need to integrate digital
habits into contemporary psychiatric assessment.
