Indigenous Cultural Identity Protects Against Intergenerational Transmission of ACEs Among Indigenous Caregivers and Their Children

A large body of empirical research has demonstrated that caregiver adverse childhood experiences (ACEs) predict ACEs in one’s child, a phenomenon known as the intergenerational transmission of ACEs. Little of this empirical research, however, has focused specifically on Indigenous peoples despite a growing body of theoretical literature and the wisdom of Elders and Traditional Knowledge Keepers that speaks to the presence of this phenomenon within Indigenous communities as well as the protective role of Indigenous cultural identity in preventing the intergenerational transmission of ACEs. The purpose of the current study was to conduct an empirical evaluation of this hypothesis, specifically that Indigenous cultural identity and social support protects against the intergenerational transmission of ACEs among Indigenous peoples and their children in the USA. Participants were 106 Indigenous women caregivers of children ages 10 to 14 in South Dakota who completed surveys. Results showed that Indigenous cultural identity moderated the association between caregiver ACEs and child ACEs. At high levels of cultural identity, there was no association between caregiver ACEs and child ACEs. At low levels of Indigenous cultural identity, however, there was a strong and positive relationship between caregiver ACEs and child ACEs. Social support did not moderate the association between caregiver ACEs and child ACEs. These findings underscore the need for initiatives that enhance Indigenous cultural identity and social support among Indigenous caregivers to prevent the intergenerational transmission of ACEs

From alcohol initiation to tolerance to problems: Discordant twin modeling of a developmental process

AbstractThe current study examined a stage-based alcohol use trajectory model to test for potential causal effects of earlier drinking milestones on later drinking milestones in a combined sample of two cohorts of Australian monozygotic and same-sex dizygotic twins (N= 7,398, ageM= 30.46,SD= 2.61, 61% male, 56% monozygotic twins). Ages of drinking, drunkenness, regular drinking, tolerance, first nontolerance alcohol use disorder symptom, and alcohol use disorder symptom onsets were assessed retrospectively. Ages of milestone attainment (i.e., age-of-onset) and time between milestones (i.e., time-to-event) were examined via frailty models within a multilevel discordant twin design. For age-of-onset models, earlier ages of onset of antecedent drinking milestones increased hazards for earlier ages of onset for more proximal subsequent drinking milestones. For the time-to-event models, however, earlier ages of onset for the “starting” milestone decreased risk for a shorter time period between the starting and the “ending” milestone. Earlier age of onset of intermediate milestones between starting and ending drinking milestones had the opposite effect, increasing risk for a shorter time period between the starting and ending milestones. These results are consistent with a causal effect of an earlier age of drinking milestone onset on temporally proximal subsequent drinking milestones.</jats:p

Rates and Correlates of Intimate Partner Abuse Among Indigenous Women Caregivers

Intimate partner abuse (IPA) is a public health crisis that disproportionately impacts indigenous women. We know little about rates and correlates of IPA victimization (IPAV) and abuse directed at one’s partner (ADP) among indigenous women caregivers (people who take care of children). The purpose of the current study was to address this critical gap in the literature. Participants were 44 indigenous women caregivers in the United States in a current relationship who completed a survey. Most women reported IPAV and ADP experiences in the past 6 months, and IPAV and ADP abuse directed at partner were positively associated. Further, IPAV was positively associated with adverse childhood experiences (ACEs), participants’ engagement in harsh parenting, and depressive symptoms. IPAV was negatively associated with age, income, indigenous cultural identity, and social support. ADP was positively associated with ACEs, harsh parenting, and depressive symptoms. ADP was negatively associated with age and income. ADP was not associated with indigenous cultural identity and social support. These data suggest the urgency with which efforts are needed to prevent and respond to IPA among indigenous women caregivers, especially those who are younger and of lower income, and that culturally grounded initiatives that seek to build social support may be especially impactful

A Test of a Conceptual Model of Sexual Self-Concept and its Relation to Other Dimensions of Sexuality

One theoretical concept that has received modest attention in contemporary sexuality research is the sexual self, particularly focusing on sexual self-concept (SSC). While research on the sexual self has expanded over the past 20 years, there is a lack of cohesion within this research that has culminated in a collection of SSC models that, while sharing certain factors, are dissimilar from each other. Therefore a unified conceptual model of SSC needs to be empirically established. Additionally, little research has examined potential differences between genders in how SSC is expressed, as most SSC research focuses exclusively on women. Finally, understanding of human sexuality can be expanded by examining SSC models in a broader sexual context via its relationship with other aspects of sexuality, such as sexual behavior, intentions, and socialization. Using Buzwell and Rosenthal’s 1996 sexual selves model as a theoretical basis, a six-factor higher-order latent SSC model was tested using confirmatory factor analysis. Lower-order factors for this model included sexual self-esteem, sexual self-efficacy, arousal, anxiety, exploration, and commitment. A five-factor latent model, after removing commitment and one sexual self-efficacy factors, was the best-fitting model, such that a higher-order SSC latent factor accounted for the correlations between these lower-order factors. This model was then tested for measurement and structural invariance between genders. Results indicated that SSC was similar on a measurement level for both men and women. Finally, a structural equation model was estimated examining the relationship between the five-factor SSC model and previous sexual behavior, intended sexual behavior, and sexual socialization. When the three sexual dimensions were examined separately, all three sexual dimensions related to the latent SSC factor for both men and women. However, when all three sexual dimensions were entered together in the model, only intended sexual behavior was significantly related to a more positive SSC for both genders. Previous sexual behavior was only significantly related to SSC in women, and sexual socialization had no relationship for either gender. These findings have important implications for both sexual self-concept research, as well as contributing to better understanding human sexuality. Adviser: Brian Wilco

Measuring Peer Socialization for Adolescent Substance Use:A Comparison of Perceived and Actual Friends’ Substance Use Effects

Objective: There has been an increase in the use of social network analysis in studies of peer socialization effects on adolescent substance use. Some researchers argue that social network analyses provide more accurate measures of peer substance use, that the alternate strategy of assessing perceptions of friends’ drug use is biased, and that perceptions of peer use and actual peer use represent different constructs. However, there has been little research directly comparing the two effects, and little is known about the extent to which the measures differ in the magnitude of their influence on adolescent substance use, as well as how these two effects may be redundant or separate constructs. Method: Using Waves I and II of the National Longitudinal Study of Adolescent Health (Add Health) saturated subsample, we directly compared effects of perception of friends’ use (PFU) and actual friends’ use (AFU) on alcohol, cigarette, and marijuana initiation and persistence of use 1 year later. We also examined potential moderating effects of friendship quality and individual use on the relationship between perceived and actual friends’ substance use and outcomes. Results: Results indicated that, overall, PFU effects were larger than AFU effects; however, these effects did not significantly differ in magnitude for most models. In addition, interaction effects differed for different substances and usage outcomes, indicating the meaning of PFU and AFU constructs (and thus, different types of peer socialization) may change based on substance and type of use. Conclusions: These results highlight the multifaceted nature of peer influence on substance use and the importance of assessing multiple aspects of peer socialization while accounting for distinct contexts related to specific substances and use outcomes

Telescoping and gender differences in the time course of disordered gambling: evidence from a general population sample

Background and AimThe course of disordered gambling in women has been described as telescoped' compared with that in men, with a later age at initiation of gambling but shorter times from initiation to disorder. This study examined the evidence, for the first time, for such a telescoping effect in a general population rather than a treatment-seeking sample

Substance use and sexual intercourse onsets in adolescence: A genetically informative discordant twin design

Purpose: Using a genetically informed, discordant twin analysis, the objective of this study was to examine whether earlier onset of drinking and smoking behaviors predicted early sexual intercourse onset
