Measuring historical trauma in an American Indian community sample: Contributions of substance dependence, affective disorder, conduct disorder and PTSD

Abstract

Background The American Indian experience of historical trauma is thought of as both a source of intergenerational trauma responses as well as a potential causative factor for long-term distress and substance abuse among communities. The aims of the present study were to evaluate the extent to which the frequency of thoughts of historical loss and associated symptoms are influenced by: current traumatic events, post traumatic stress disorder (PTSD), cultural identification, percent Native American Heritage, substance dependence, affective/anxiety disorders, and conduct disorder/antisocial personality disorder (ASPD). Methods Participants were American Indians recruited from reservations that were assessed with the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA), The Historical Loss Scale and The Historical Loss Associated Symptoms Scale (to quantify frequency of thoughts and symptoms of historical loss) the Stressful-Life-Events Scale (to assess experiences of trauma) and the Orthogonal Cultural Identification Scale (OCIS). Results Three hundred and six (306) American Indian adults participated in the study. Over half of them indicated that they thought about historical losses at least occasionally, and that it caused them distress. Logistic regression revealed that significant increases in how often a person thought about historical losses were associated with: not being married, high degrees of Native Heritage, and high cultural identification. Additionally, anxiety/affective disorders and substance dependence were correlated with historical loss associated symptoms. Conclusions In this American Indian community, thoughts about historical losses and their associated symptomatology are common and the presences of these thoughts are associated with Native American Heritage, cultural identification, and substance dependence.

Historical Trauma and Substance Use among Native Hawaiian College Students

“…Eight items adapted from the historical loss scale used in previous research among American Indians 12-15 were employed (Table 2). Participants were asked how often they thought (eg, several times a day, daily, weekly, monthly, yearly/special times, never) about various types of historical or cultural loss (eg, loss of land, loss of language, loss of their people from early dead, loss of respect by children for elders).…”

“…9,10,11 According the 2001–2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) of adults 18 years and older, the prevalence of drinking for AI/ANs was 70.7%, compared with 77.1% for Whites, 60.1% for Blacks, and 60.4% for Hispanics. In addition, AI/AN individuals had the highest prevalence of exceeding the recommended daily and weekly drinking limits (53% and 27.4% of the population exceeding the two limits, respectively) compared with Whites (52.5% and 17.3%, respectively), Blacks (29% and 8.9%), and Hispanics (37.3% and 8.5%).…”

Stressful life events, ethnic identity, historical trauma, and participation in cultural activities: Associations with smoking behaviors among American Indian adolescents in California

“…The emotional consequences of HT are transmitted to subsequent generations through physiological, environmental and social pathways (Brave Heart, 2003; Danieli, 1998; Duran & Duran, 1995; Sotero, 2006). HT is associated with impaired family communication (Evans-Campbell, 2008), PTSD symptoms, survivor guilt, anxiety, depression, cultural identity, and substance use (Whitbeck, Adams, Hoyt, & Chen, 2004; Ehlers, Gizer, Gilder, Ellingson, & Yehuda, 2013). We conceptualize HT as a mediator between three predictor variables (EI, participation in cultural activities, and SLEs) and smoking.…”
