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

Dramatic 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.

A 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.

Female 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_t to week_t+1 were associated with a higher likelihood of a positive STB status at week_t+1; and (2) higher expressive suppression, perceived burdensomeness, and caregiver criticism and conflict at week_t compared to participants' mean levels prospectively predicted increases in the likelihood of a positive STB report from week_t to week_t+1.

Psychosocial 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.

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.

We worked to ensure race, ethnic, and/or other types of diversity in the recruitment of human participants. We worked to ensure that the study questionnaires were prepared in an inclusive way. One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented racial and/or ethnic groups in science. One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented sexual and/or gender groups in science. While citing references scientifically relevant for this work, we also actively worked to promote sex and gender balance in our reference list.
