Item Lifetime Adversities, Risk, Resilience and Family Cohesion Among a National Sample of Latinx Immigrants Living in the U.S.(2019-05) Cooper, DanielBackground: The research literature provides strong evidence of the adverse impact of cumulative stress on individual and family life. The purpose of this study was to (a) examine the construct validity of a cumulative measure of lifetime adversities and (b) assess the moderating effects of several cultural risk (acculturation stress, perceived discrimination) and protective factors (social support, ethnic identity) on the relationship between cumulative lifetime adversities and family cohesion among U.S. Latinx immigrants. Method: Data came from a cross-sectional secondary dataset, called the HCHS – SOL Sociocultural Ancillary Study. The sample (N = 3,632) was identified using stratified random probability sampling in four of the largest Latinx metropolitan areas: the Bronx, San Diego, Chicago, and Miami. Six Latinx subgroups were included in this study: Puerto Ricans, Cubans, Mexicans, Dominicans, South Americans, and Central Americans. Results: Results from a confirmatory factor analysis supported a three-factor model of cumulative lifetime adversities, including childhood trauma, current stress, and chronic stress. Invariance testing suggested that the measure functioned equivalently across the six Latinx subgroups. Results from a latent moderation analysis suggested that social support buffered the association between cumulative lifetime adversities and family cohesion; whereas discrimination exacerbated the association between cumulative lifetime adversities and family cohesion. Unexpectedly, acculturation stress buffered the association between cumulative lifetime adversities and family cohesion. Several potential explanations are discussed. Conclusions: Results can be used to inform the development of mental health interventions and prevention programs tailored to the specific needs of Latinx immigrant populations exposed to adversity and cultural stressors. Implications for the immigrant paradox are also discussed.Item A Proposed Algebra Problem-Analysis Model(2015-08) Walick, ChristopherThe National Mathematics Advisory Panel (2008) states that algebra is a gateway to high school graduation and college success. While existing research emphasizes the importance of quality algebra instruction, the current body of research on algebra problem-analysis for struggling secondary students is small. This paper proposes a problem-solving model to help support those students struggling with algebra. The model integrates the recommendations from math policy boards and research. It is composed of five core sections, each section focusing on a specific critical component of school algebra. The study examines the relationship between the five skills within the model to an established measure of algebra, as well as the validity of the measures being used to assess the different skill areas The results indicate that there is a significant relationship between the five sections of the model and algebra proficiency, and that the model is able to identify non-proficiency students with a high degree of accuracy.
