Intrusions related to indirectly experienced events in clinical offspring of World War Two survivors.

Negative events may not only linger on in the form of intrusive memories in the minds of those directly exposed but also in those who are only indirectly confronted with these events. The aim of the present study was to investigate if intrusions referring to indirectly experienced traumatic events do indeed occur, and to compare their frequency and characteristics to intrusions about directly experienced negative events. Participants (N = 98) were adult postwar offspring of World War Two survivors currently in treatment in one of two clinics specialized in the treatment of war victims. We examined the frequency and characteristics of intrusions about indirectly experienced (i.e., parent war-related) events and two types of directly (self-) experienced events: Self-experienced traumatic events and negative events related to participants' upbringing. Intrusions referring to indirectly experienced traumatic events did indeed occur. The frequency as well as other characteristics of these intrusions did not differ from those of both types of intrusions about directly experienced events. The similarities between intrusions related to different types of events emphasize the (re)constructive nature of memory. Our findings indicate that traumatic events not only affect those directly involved but may also continue to plague the next generation.

Intergenerational consequences of the Holocaust on offspring mental health: a systematic review of associated factors and mechanisms.

Exposure to war and violence has major consequences for society at large, detrimental impact on people's individual lives, and may also have intergenerational consequences. To gain more insight into these intergenerational consequences, research addressing the impact of the Holocaust on offspring is an important source of information. The aim of the current study was to systematically review the mechanisms of intergenerational consequences by summarizing characteristics in Holocaust survivors and their offspring suggested to impact the offspring's mental health. We focused on: 1) parental mental health problems, 2) (perceived) parenting and attachment quality, 3) family structure, especially parental Holocaust history, 4) additional stress and life events, and 5) psychophysiological processes of transmission. We identified 23 eligible studies published between 2000 and 2018. Only Holocaust survivor studies met the inclusion criteria. Various parent and child characteristics and their interaction were found to contribute to the development of psychological symptoms and biological and epigenetic variations. Parental mental health problems, perceived parenting, attachment quality, and parental gender appeared to be influential for the mental well-being of their offspring. In addition, having two survivor parents resulted in higher mental health problems compared to having one survivor parent. Also, there was evidence suggesting that Holocaust survivor offspring show a heightened vulnerability for stress, although this was only evident in the face of actual danger. Finally, the results also indicate intergenerational effects on offspring cortisol levels. Clinical and treatment implications are discussed.

La exposición a la guerra y la violencia tiene consecuencias importantes para la sociedad en general, un impacto perjudicial en la vida individual de las personas, y también puede tener consecuencias intergeneracionales. Para obtener más información sobre estas consecuencias intergeneracionales, la investigación que aborda el impacto del Holocausto en la descendencia es una fuente importante de información. El objetivo del presente estudio fue revisar sistemáticamente los mecanismos de las consecuencias intergeneracionales resumiendo las características de los sobrevivientes del Holocausto y sus descendientes, que podrían impactar la salud mental de la descendencia. Nos centramos en: 1) los problemas de salud mental de los padres, 2) la calidad (percibida) de la crianza y el apego, 3) la estructura familiar, especialmente antecedentes del Holocausto de los padres, 4) el estrés y los eventos de la vida adicionales, y 5) los procesos psicofisiológicos de la transmisión. Identificamos 23 estudios elegibles publicados entre 2000 y 2018. Solo los estudios de sobrevivientes del Holocausto cumplieron con los criterios de inclusión. Se descubrió que diversas características de los padres y de los hijos y su interacción contribuyen al desarrollo de los síntomas psicológicos y las variaciones biológicas y epigenéticas. Los problemas de salud mental de los padres, la crianza percibida, la calidad del apego, y el género parental parecieron influir en el bienestar mental de sus hijos. Además, tener dos padres sobrevivientes resultó en mayores problemas de salud mental en comparación con tener uno de los padres sobrevivientes. Además, hubo evidencia que sugiere que los descendientes de los sobrevivientes del Holocausto muestran una mayor vulnerabilidad al estrés, aunque esto fue solo evidente ante el peligro real. Finalmente, los resultados también indican los efectos intergeneracionales en los niveles de cortisol de la descendencia. Se discuten las implicaciones clínicas y de tratamiento.
