The purpose of this study was to construct a scale to measure how adolescents question the meaning of life. It was administered to 336 college students. Factor analysis revealed a 3-factor structure: doubting the value of life, questioning the purpose of life, and questioning the basis of existence. We investigated the relationships among the experience of questioning the meaning of life, purpose in life (PIL), the Big five personality traits, and sense of identity. We found that the experience of questioning the meaning of life is associated with a lack of a meaningful life, personality traits like neuroticism, and a poor sense of identity. Further, each factor had different content.
