Neuroticism in familial depression.

R Katz, P McGuffin

    Psychological Medicine
    |February 1, 1987
    PubMed
    Summary

    Neuroticism (N) is strongly linked to current depression in individuals with a family history of the illness. This personality trait appears to be a state of being depressed, not a predictor of future depression.

    Area of Science:

    • Psychiatry
    • Clinical Psychology
    • Behavioral Science

    Background:

    • Familial vulnerability to depression is a significant risk factor.
    • Understanding personality traits associated with depression is crucial for early intervention.

    Purpose of the Study:

    • To investigate the relationship between personality factors and depression in individuals with a familial predisposition.
    • To differentiate between personality traits as a liability versus a state associated with current depressive symptoms.

    Main Methods:

    • Study included four groups of first-degree relatives of depressed patients.
    • Assessed personality characteristics: Psychoticism, Extraversion, Neuroticism (N), and Lie scale.
    • Compared personality scores across groups based on current and past depressive episodes.

    Main Results:

    • Neuroticism (N) was the only personality factor showing significant differences between groups.
    • A strong association was found between current depression and higher Neuroticism scores.
    • Past history of depression was linked to elevated N scores, but this was associated with current depressive symptomatology.

    Conclusions:

    • Neuroticism (N) is strongly associated with the state of being depressed, not necessarily a stable trait predicting liability.
    • Findings suggest that elevated N scores in individuals with a history of depression may reflect current symptomatology.
    • Further research is needed to clarify the role of personality traits in the trajectory of depression in vulnerable populations.
