Abstract: | To date, little is known about how perceptions of life meaning are formed, although recent evidence suggests that “basic attitudes about the meaning of existence are commonly rooted in evolved biological factors and conjointly influenced through people’s experiences with life” (Steger et al. in J Posit Psychol 6:181–191, 2011a). In line with this view, we proposed that multidimensional aspects of adult attachment security and trait authenticity would independently predict perceptions regarding the presence and search for life meaning. Correlational findings largely supported hypothesized relationships among these variables. Regression findings further demonstrated that adult attachment orientations and trait authenticity uniquely predicted the presence of life meaning, and made more modest contributions to the search for meaning. In both predictions, experiences of self-alienation appeared to function as a mediator of the relationship between attachment security and meaning in life perceptions. Implications of our findings for advancing understanding of the formation of these perceptions are discussed. |
