This study investigates the impact of the childhood family environment on reported meaning in life among emerging adults (n= 507) at a private, urban, religious university. This study found that participants who reported growing up in an emotionally warm family environment ultimately reported more meaning in life as adults and that this effect was mediated by loneliness. This suggests that people from emotionally cold and rejecting early family environments may struggle with meaning in life as adults because they are lonelier. This research contributes a developmental perspective to understanding meaning in life. The public health implications of these findings are discussed. Future research should consider accounting for the effects of early life experiences on meaning in life.
