Introduction:
Youth suicide is a worldwide public health and social issue. Suicidal ideation (SI), which spans a spectrum of thoughts from mild cognitions about death to serious and specific plans about taking one's life, is a significant risk factor for actual completed suicide. Thus, it is important to identify the environmental factors and psychological mechanisms that affect SI in adolescents.
Methods:
A sample of 607 Chinese high school students (Mage = 16.20, SD = 0.55) participated. Latent growth curve modeling was used to examine developmental trends in emotional problems and SI, incorporating a four-wave longitudinal design over a 1-year interval. A longitudinal mediation model was constructed to examine the effects of the intercept and slope of emotional problems in the relation between negative life events and SI.
Results:
The results indicated that: (1) adolescents demonstrated a linear decrease in emotional problems and SI during the follow-up period, and the higher the initial level, the slower the growth rate; (2) negative life events demonstrated a significant positive predictive effect on the initial level of adolescent SI; and (3) negative life events played an indirect role in the initial level of adolescent SI through the initial level of emotional problems.
Conclusions:
Negative life events and emotional problems are influential factors in the level of SI in adolescents; however, further research is needed regarding the rate of change in SI.
