Preadolescent Suicidal Thoughts and Behaviors: An Intensive Longitudinal Study of Risk Factors.

objectiveDramatic increases in rates of suicidal thoughts and behaviors (STBs) among youth highlight the need to pinpoint early risk factors. This study used intensive longitudinal sampling to assess what the concurrent associations were between risk factors and STB status, how proximal changes in risk factors were related to STB status, and how risk factors prospectively predicted changes in STB status in a preadolescent sample enriched for early childhood psychopathology.

methodA total of 192 participants were included from the Parent-Child Interaction Therapy-Emotional Development (PCIT-ED) Study, a longitudinal study of children with and without preschool depression. Participants 7 to 12 years of age completed a diagnostic interview, followed by 12 months of intensive longitudinal sampling, assessing experiences of suicidal ideation and 11 psychosocial variables with known links to STBs in adolescents and adults. Preadolescents with STB history (high-risk) received surveys weekly, and those without STB history (lower-risk) received surveys monthly.

resultsFemale sex, elevated depressive symptoms, greater use of expressive suppression and rumination, emotional clarity, and perceived burdensomeness were uniquely concurrently associated with the likelihood of STB endorsement. Within the high-risk group, (1) increases in depression, expressive suppression, rumination, and perceived burdensomeness, and decreases in positive affect from week

conclusionPsychosocial factors influencing STBs in adolescents and adults also affect preadolescents in day-to-day life. Expressive suppression and perceived burdensomeness consistently emerged as novel risk indicators and potential targets for treatment. In addition, increases in depression, rumination, and caregiver criticism and conflict, as well as decreases in positive affect, might prompt heightened STB screening and assessments for preadolescents with a history of STBs. PLAIN LANGUAGE SUMMARY: There have been large increases in rates of suicidal thoughts and behaviors (STBs) among youth, highlighting the need to identify early risk factors in preadolescents. Over one year, 192 seven- to 12-year-old Midwestern children, some of whom had a history of STBs, repeatedly reported on several risk factors and occurrence of STBs over the previous week or month. Suppressing one's emotions and feeling like a burden emerged as risk factors and predicted the increased likelihood of the emergence of STBs, suggesting these may be potential targets for treatment. Findings also suggest that increases in depression, rumination, and caregiver criticism and conflict, as well as decreases in positive emotion, should prompt STB screening and assessments for preadolescents with a history of STBs.
