Personal values in adolescence and suicidality: a cross-sectional study based on a retrospective recall

This study retrospectively examined the association between personal values in adolescence and suicidality in a community-representative adult sample in Japan.

Data were used from wave 1 (2010) and wave 3 (2017) of a Japanese Study on Stratification, Health, Income, and Neighborhood (J-SHINE) survey. Personal values at age 15 were retrospectively measured in 2017 in two ways: the original value priorities we made were based on the Schwartz theory of basic values; and the Japanese version of the Personal Values Questionnaire II (PVQ-II) was used to assess the degree of commitment to the values. Multivariate logistic regression analysis was used to estimate the association of personal values in adolescence with self-reported suicidal ideation, suicidal planning, and suicide attempt (both during a lifetime and in the most recent year), adjusting for socio-demographics, smoking, alcohol consumption, and economic status among 15 year olds.

Cherishing family and friends was significantly and negatively associated with suicidal ideation over a lifetime and in the most recent year. Commitment to values was also significantly and negatively associated with suicidal ideation in the most recent year.

Investigating the association between personal values and suicidality could make a significant contribution to the literature by offering a new approach to understanding and preventing suicide.
