Childhood Adversities and Thriving Skills: Sample Case of Older Swiss Former Indentured Child Laborers

The study of life-long consequences of severe childhood adversities or trauma has recently received much attention. However, little is known about the subjective coping success and development of positively evaluated resources that may originate within these adverse experiences and may be conceptualized as thriving. This study set out to examine the relationship between thriving in response to early adversity and successful aging with a sample of former indentured child laborers in Switzerland (Verdingkinder). Participants were screened according to subjective and objective health-related attributes, and those who were evaluated to be "successful agers" were included. Semistructured interviews were conducted with 12 former Verdingkinder (mean age: 71 years) that lasted 60-120 minutes. The interviews were analyzed using the paradigm model of the Grounded Theory. In the interviews adverse experiences and negative consequences were reported. However, where thriving was triggered in response to these experiences, the factors identified as "lightheartedness," "social purpose," and "self-enhancement" were associated with successful aging. Factors including motivation, reflection, personality traits, social support, individual coping strategies, turning points, and processing were reported as central to thriving. The identified factors show similarities with established predictors of health and well-being. Thus, under certain circumstances early and prolonged adverse experiences can also provide the opportunity to develop positive resources for successful aging.

DNA methylation profiles of elderly individuals subjected to indentured childhood labor and trauma

BackgroundChildhood trauma is associated with increased vulnerability to mental and somatic disorders later in life. Epigenetic modifications such as DNA methylation are one potential mechanism through which such long-lasting impairments/consequences can be explained. The aim of the present study was to investigate whether childhood trauma is associated with long-term DNA methylation alterations in old age.MethodsWe assessed genome-wide DNA methylation profiles in a cohort of former indentured child laborers (“Verdingkinder”) who suffered severe childhood adversities (N = 30; M age = 75.9 years), and compared them to control group with similar demographic characteristics (N = 15, M age = 72.8 years). DNA was isolated from epithelial buccal cells and hybridized to the Illumina Infinium 450 k DNA methylation array, which provides coverage of 485,000 methylation sites.ResultsAfter accounting for batch effects, age, gender and multiple testing, 71 differentially methylated CpG positions were identified between the two groups. They were annotated among others to genes involved in neuronal projections and neuronal development. Some of the identified genes with differential methylation (DLG associated protein 2, mechanistic target of rapamycin) have previously been associated with traumatic stress.ConclusionsThe results indicate specific epigenetic alterations in elderly individuals who were subjected to childhood adversities. Psychiatric and somatic comorbidities as well as differences in buccal epithelial cells proportion may contribute to the observed epigenetic differences.

Posttraumatic Stress Disorder, Adverse Childhood Events, and Buccal Cell Telomere Length in Elderly Swiss Former Indentured Child Laborers.

Posttraumatic stress disorder (PTSD) is associated with increased risk for age-related diseases and early mortality. Accelerated biological aging could contribute to this elevated risk. The aim of the present study was to assess buccal cell telomere length (BTL) – a proposed marker of biological age – in men and women with and without PTSD. The role of childhood trauma was assessed as a potential additional risk factor for shorter telomere length. The sample included 62 former indentured Swiss child laborers (age: M = 76.19, SD = 6.18) and 58 healthy controls (age: M = 71.85, SD = 5.97). Structured clinical interviews were conducted to screen for PTSD and other psychiatric disorders. The Childhood Trauma Questionnaire (CTQ) was used to assess childhood trauma exposure. Quantitative polymerase chain reaction was used to measure BTL. Covariates include age, sex, years of education, self-evaluated financial situation, depression, and mental and physical functioning. Forty-eight (77.42%) of the former indentured child laborers screened positive for childhood trauma, and 21 (33.87%) had partial or full-blown PTSD. Results did not support our hypotheses that PTSD and childhood trauma would be associated with shorter BTL. In fact, results revealed a trend toward longer BTL in participants with partial or full PTSD [F(2,109) = 3.27, p = 0.04, η2 = 0.06], and longer BTL was marginally associated with higher CTQ scores (age adjusted: β = 0.17 [95% CI: −0.01 to 0.35], t = 1.90, p = 0.06). Furthermore, within-group analyses indicated no significant association between BTL and CTQ scores. To the best of our knowledge, this is the first study exploring the association between childhood trauma and BTL in older individuals with and without PTSD. Contrary to predictions, there were no significant differences in BTL between participants with and without PTSD in our adjusted analyses, and childhood adversity was not associated with BTL. Possible explanations and future research possibilities are discussed.

Sexual Behavior and Concerns in a Sample of Elderly, Former Indentured Swiss Child Laborers.

IntroductionPast research suggests a link between post‐traumatic stress disorder (PTSD) and an increased risk for sexual problems. However, there is still no clear picture whether these higher rates are related to trauma exposure or to PTSD itself.AimThe aim of the present study was to complement existing knowledge on the relative impact of trauma and PTSD on sexuality in later life, considering different aspects of trauma exposure on both men and women.MethodsThe study was conducted on a unique population sample of former Swiss indentured child laborers (55 men, M age 78, age range 60–95 years) who have repeatedly experienced a variety of severe childhood traumas.Main Outcome MeasuresSexual outcomes were measured using two scales from the Trauma Symptom Inventory—Dysfunctional Sexual Behavior (DSB) and Sexual Concerns (SC). PTSD symptoms and trauma were assessed with the Short Screening Scale for PTSD and the Composite International Diagnostic Interview, respectively.ResultsTwenty‐two individuals showed PTSD symptoms, and 53 reported having experienced childhood trauma. Significant differences between men and women were reported for DSB and SC. Men reported a significantly higher prevalence of both SC and DSB compared with women.ConclusionsThis is the very first study investigating DSB and SC in a sample of older adults exposed to similar traumatic experiences and settings. However, some study limitations need to be considered such as the small sample size. Additional studies are needed to further explore the relative role of traumatization and PTSD on sexual behavior and well‐being, especially to improve sexual therapy for patients who experience trauma.

Childhood trauma and resilience in old age: applying a context model of resilience to a sample of former indentured child laborers

Objectives: Psychological resilience has been rarely investigated in elderly populations. We applied a more comprehensive model of trauma-specific coping and resilience, which included Ungar's context model and included decentral factors of resilience (i.e., environments that provide resources to build resilience).Method: We assessed resilience in a cohort of former Swiss indentured child laborers (N = 74; 59% males) at two time points; first at the mean age of 80 years and then again 20 months later. At each time point, the following measures of resilience were assessed: resilience indicators of life satisfaction and lack of depression. In addition, resilience predictors of trauma exposure, perceived social support, dysfunctional disclosure of traumatic experiences, social acknowledgment as a victim, and self-efficacy; and decentral resilience factors of education, income, number of children, and physical health were measured.Results: Using path-analysis, we found that life satisfaction and lack of depression were predicted by dysfunctional disclosure, social support, and self-efficacy at various significance levels. Change scores of resilience were predicted by higher trauma exposure, social acknowledgment as a victim, and an interaction between the two. The model for decentral factors also fitted, with physical health and income predicting the resilience indicators.Conclusion: Applying this comprehensive resilience model in a sample of older adults revealed meaningful findings in predicting resilience at a single time point and over time. Atypical coping strategies, such as perceived social acknowledgment as a victim and disclosure, may be particularly important for former victims who have suffered institutional abuse.

Developmental and contextual factors in the role of severe childhood trauma in geriatric depression: The sample case of former indentured child laborers

The purpose of this study was to quantify the association between childhood traumatic experiences and geriatric depression (GDS) in a population of elderly who were exposed to severe childhood trauma. We aimed to identify the role of childhood maltreatment exposure in geriatric depression and the developmental and contextual factors that exacerbate this relationship. We interviewed 141 former indentured child laborers (58 females) about their experiences as children and their current depressive symptoms (Mage=77, SD=6.8). Participants provided their age, the year they were first indentured, duration indentured, current physical health, completed the Childhood Trauma Questionnaire (CTQ) and the Geriatric Depression Scale (GDS). Child maltreatment, specifically emotional abuse, was strongly associated with geriatric depression symptoms. These effects were specific to individuals who were removed from their biological families between the ages of 3 and 9 years, and for children who were indentured for 6–12 years. Finally, depression partially mediated the association between medical conditions and daily health impairment, but not for individuals “at risk” for depression by virtue of their maltreatment experiences. This study was conducted with a specific subpopulation of elderly and therefore may not generalize to all geriatric depression, nor to all generations or populations with exposure to childhood adversity. This study demonstrates the importance of using a developmental framework to understand how childhood maltreatment facilitates increased risk for the development of depression in late life.

Childhood trauma and PTSD symptoms increase the risk of cognitive impairment in a sample of former indentured child laborers in old age.

A growing body of evidence suggests a link between early childhood trauma, post-traumatic stress disorder (PTSD) and higher risk for dementia in old age. The aim of the present study was to investigate the association between childhood trauma exposure, PTSD and neurocognitive function in a unique cohort of former indentured Swiss child laborers in their late adulthood. To the best of our knowledge this is the first study ever conducted on former indentured child laborers and the first to investigate the relationship between childhood versus adulthood trauma and cognitive function. According to PTSD symptoms and whether they experienced childhood trauma (CT) or adulthood trauma (AT), participants (n = 96) were categorized as belonging to one of four groups: CT/PTSD+, CT/PTSD-, AT/PTSD+, AT/PTSD-. Information on cognitive function was assessed using the Structured Interview for Diagnosis of Dementia of Alzheimer Type, Multi-infarct Dementia and Dementia of other Etiology according to ICD-10 and DSM-III-R, the Mini-Mental State Examination, and a vocabulary test. Depressive symptoms were investigated as a potential mediator for neurocognitive functioning. Individuals screening positively for PTSD symptoms performed worse on all cognitive tasks compared to healthy individuals, independent of whether they reported childhood or adulthood adversity. When controlling for depressive symptoms, the relationship between PTSD symptoms and poor cognitive function became stronger. Overall, results tentatively indicate that PTSD is accompanied by cognitive deficits which appear to be independent of earlier childhood adversity. Our findings suggest that cognitive deficits in old age may be partly a consequence of PTSD or at least be aggravated by it. However, several study limitations need to considered. Consideration of cognitive deficits when treating PTSD patients and victims of lifespan trauma (even without a diagnosis of a psychiatric condition) is crucial. Furthermore, early intervention may prevent long-term deficits in memory function and development of dementia in adulthood.
