Sidney Blatt's theory integrates psychoanalytic, cognitive, and developmental psychology to understand depression. The Depressive Experience Questionnaire (DEQ) measures anaclitic (dependency) and introjective (self-critical) dimensions of depression, validated in adults and adolescents.

Area of Science:

  • Psychology
  • Psychopathology
  • Developmental Psychology

Background:

  • Traditional categorical-symptomatic approaches to depression are insufficient.
  • Sidney Blatt proposed a theory integrating psychoanalytic, cognitive, and developmental psychology.
  • Personality development arises from establishing interpersonal relationships and a sense of self/identity.

Purpose of the Study:

  • To validate Sidney Blatt's model of psychopathology, emphasizing continuities between normal and pathological depression.
  • To assess the construct validity of the Depressive Experience Questionnaire (DEQ) and its adolescent form (DEQ-A).
  • To examine the French translation of the DEQ and DEQ-A in a large population.

Main Methods:

  • Development of the Depressive Experience Questionnaire (DEQ) with 66 items.

  • Administration to large nonclinical samples of adults and adolescents.
  • Principal component analysis and exploratory factor analysis to identify depressive dimensions.
  • Validation of French translations of DEQ and DEQ-A.

    • Main Results:

    • The DEQ identified two principal depressive dimensions: anaclitism (interpersonal relationships) and self-criticism (self-identity), plus efficacy.
    • Factor structure and dimensions were highly congruent across sexes and replicated in various samples.
    • DEQ-A showed similar factor structures, demonstrating reliability, internal consistency, and validity.
    • Anaclitism and self-criticism dimensions correlated positively with depression measures.
    • Anaclitism was less differentiated in males than females, suggesting gender-specific relevance of dependency.

    Conclusions:

    • Blatt's model, differentiating self-criticism from dependency in depression, is supported by the DEQ and DEQ-A.
    • These dimensions align with other theoretical perspectives on depression subtypes.
    • The DEQ and DEQ-A are valid instruments for assessing these depression dimensions in adults and adolescents.
    • Gender differences in the manifestation of anaclitism warrant further investigation.
