Age differences in personality structure revisited: Studies in validity, stability, and change.

P T Costa, R R McCrae

    International Journal of Aging & Human Development
    |January 1, 1977
    PubMed
    Summary

    This study validates personality dimensions of Anxiety, Extraversion, and Openness in adult males, finding stability for Anxiety and Extraversion over nine years. Openness validity was supported by external correlates despite structural changes.

    Area of Science:

    • Psychology
    • Personality Psychology
    • Psychometrics

    Background:

    • Understanding personality structure and stability is crucial in psychology.
    • Previous research has identified key personality dimensions, but their longitudinal stability and construct validity require ongoing investigation.
    • The structural approach to personality development offers insights into how personality traits evolve over time.

    Purpose of the Study:

    • To examine construct validity and longitudinal stability for three personality cluster dimensions: Anxiety, Extraversion, and Openness.
    • To provide evidence supporting the interpretation of these personality clusters through correlations with established psychological scales.
    • To investigate the longitudinal stability of personality dimensions over extended periods and reconsider changes in personality structure.

    Main Methods:

    • Correlational analyses were used to assess construct validity by comparing the three personality clusters with the Allport-Vernon-Lindsay Value scales, Cornell Medical Index scores, Eysenck E and N scales, and SVIB factors.
    • Longitudinal data were collected over nine and eleven years to assess the stability of personality scores and structural changes.
    • The study examined the relationship between field-dependence and tendermindedness in different age groups to illustrate personality development.

    Main Results:

    • Correlations supported the construct validity and interpretation of the Anxiety, Extraversion, and Openness personality dimensions.
    • Anxiety and Extraversion scores demonstrated nine-year longitudinal stability.
    • While eleven-year longitudinal data did not replicate earlier structural differences in Openness, external correlates confirmed its validity as a personality dimension.

    Conclusions:

    • The study provides robust evidence for the construct validity and longitudinal stability of Anxiety and Extraversion in adult males.
    • The findings support the validity of an Openness dimension, even when structural changes are observed over time.
    • The research highlights the utility of a structural approach in understanding personality development and age-related differences in psychological constructs.
