Does early life trauma affect how depression is experienced by Holocaust survivors in late life?

Existing research indicates that early life trauma increases the likelihood of depression in later life. This includes children who survived the Nazi Holocaust living in Israel today. For this study, we set out to examine whether early life trauma affects both levels of depression symptomatology and the relative prominence of certain facets of depression as compared to other older adults in Israel and Canada.

For this study we recruited 295 Holocaust survivors (HS), 205 other Israelis and 335 older Canadians each of whom completed Radloff's (1977) Center for Epidemiological Studies - Depression Scale (CES-D). The CES-D measures four distinct factors: Depressive affect, absence of well-being, somatic symptoms, and interpersonal rejection. Israeli and Canadian comparison participants were screened to ensure they had not experienced early life trauma.

As anticipated, levels of depressive symptoms reported by HS were significantly greater than other Israelis and older Canadians. Moreover, the latent structure of depression as measured by the CES-D differs for HS. Depressive affect and the absence of well-being appear to distinguish depression among HS. Somatic symptoms do not differ, however, and interpersonal rejection seems less germane to depression as experienced by HS compared to both comparison samples.

Findings support our assertion that early life trauma affects not only levels of depressive symptoms but also that these survivors of genocide experience depression differently than other Israelis and older Canadians. We discuss the implications of early life trauma for mental health in later life.
