Fiche synthèse

1. Objectifs


Intentions :
« The current study tested the diathesis-stress component of the hopelessness theory (HT) in a sample of youth using (1) a weakest link approach towards operationalizing cognitive vulnerability [...] and (2) an idiographic approach towards operationalizing high stress [...]. We also examined whether the association between within-subject fluctuations in hassles and depressive symptoms in cognitively vulnerable youth was moderated by absolute stress levels (the between-subject affect of stress). » (p. 377)

Questions/Hypothèses :
- « We hypothesized that a depressogenic weakest link would be associated with greater increases in depressive symptoms following increases in hassles. » (p. 381)
- Also, « we hypothesized that the strength of this association would be moderated by the between-subject effect of stress with children reporting a level of stress that is high, rather than low, in comparison with the sample’s average level of stress reporting the greatest increases in depressive symptoms. » (p. 382)
- « In addition, [...] children’s gender was examined as a potential moderator of this relationship. » (p. 382)

2. Méthode


Échantillon/Matériau :
« [...] 140 children [from Montreal city] (between 6 and 14 years of age) of parents with a history of major depressive episodes [...] » (p. 377)

Instruments :

- « Child depression inventory » (CDI; Kovacs, 2003) ;
- « Hassles scale for children » (CHAS; Kanner et al., 1987);
- « Children’s attributional style questionnaire » (CASQ; Seligman et al., 1984);
- « Children’s cognitive style questionnaire » (CCSQ; Abela, 2001). (p. 383-385)

3. Résumé


« A multi-wave longitudinal design was used to examine whether the association between within-subject fluctuations in hassles and depressive symptoms was moderated by a depressogenic weakest link. [...] At Time 1, [...] [participants] completed measures assessing DISs and depressive symptoms. Every 6 weeks, for the subsequent year, children completed measures assessing depressive symptoms and hassles. [...] The results of hierarchical linear modelling analyses indicated that a depressogenic weakest link was associated with greater elevations in depressive symptoms following elevations in hassles in girls but not in boys. [...] Results provide partial support for the applicability of the diathesisstress component of the HT to youth. Integration of the current findings with those obtained in past research examining the diathesis-stress component of the hopelessness theory in youth suggests the utilization of an idiographic approach to examining vulnerability–stress theories may potentially lead to an increased understanding of gender differences in depression. » (p. 377)
