Criminogenic risk factors among immigrants in the U.S.–México border region
Latinx High School Students’ Reflections About a University Summer Research Program Support the Use of Asset Bundles in Designing Programs for Broadening STEM Pipelines
Latinx individuals are under-represented in STEM and biomedical fields. Research by Johnson and Bozeman has shown that the asset bundle framework can be used to help minoritized individuals succeed in STEM and professional schools. This model has been widely applied to college students, but little work has been done with high school students. A formalized summer research program to allow students to participate in university research was implemen…

Comparing legal attitudes of Anglo- and Latino-Americans
The Legal Attitudes Questionnaire (LAQ) is a commonly used measure of juror bias; however, the factor structure of the English-language version of this measure has yet to be confirmed. This research compared the model fit of three competing models of the English-language LAQ within 504 Anglo-American and 290 Latino-American students. Results indicated that the Couch and Sundre (2001 Couch, J. V., & Sundre, D. L. (2001). Legal attitudes scale: A f…
Coefficient α as a Measure of Test Score Reliability
We discuss 3 popular misconceptions about Cronbach α or coefficient α, traditionally used in public health and the behavioral sciences as an index of test score reliability. We also review several other indices of test score reliability. We encourage researchers to thoughtfully consider the nature of their data and the options when choosing an index of reliability, and to clearly communicate this choice and its implications to their audiences
Assessing the Gender Invariance of the Modern Homonegativity Scale
The measurement invariance of the Modern Homonegativity Scale (MHS) was examined among heterosexual female (n = 449) and male (n = 329) university students who were predominantly Mexican American. The MHS demonstrated full invariance of factor loadings and partial invariance of latent intercepts. At the latent mean level, heterosexual men compared to heterosexual women held more negative attitudes toward both gay men and lesbian women. There were…
Important Considerations in Conducting Statistical Mediation Analyses
An investigator wishes to examine mediation in a randomized control trial of the effectiveness of an intervention, which consists of a computerized decision aid for promoting colorectal cancer screening. Mediation is a naturally occurring process, and in any given instance, research investigators seek to ascertain whether it has occurred. In the case of a prevention intervention for a specific chain of events, mediation occurs (1) when the preven…
A Profile of US-Mexico Border Mobility Among a Stratified Random Sample of Hispanics Living in the El Paso-Juarez Area
Effectiveness and Spillover of an After-School Health Promotion Program for Hispanic Elementary School Children
Objectives. We evaluated the effectiveness and spillover of an after-school health education and physical activity program among Hispanic elementary school children. Methods. In fall 2008, students in third through fifth grades in 6 schools in El Paso, Texas (n = 901), were randomized to intervention (n = 292 participants) or control (n = 354) classrooms (4 unknown). Intervention classrooms also contained a spillover group (n = 251) that did not …
Measuring social problem solving using the Spanish Version for Hispanics of the Social Problem Solving Inventory–Revised
This study investigated the internal consistency, factor structure, and concurrent validity of the Social Problem Solving Inventory-Spanish Version for Hispanics (SPSI-R-Hispanic), a translation of the Social Problem Solving Inventory-Revised (SPSI-R; D'Zurilla, Nezu & Maydeu-Olivares, 2002), in a North American sample of 325 Spanish speaking Hispanics. The scales of the SPSI-R-Hispanic demonstrated good internal consistency reliability. The hypo…
Reliability and Validity of the Novaco Anger Scale and Provocation Inventory (NAS-PI) and State-Trait Anger Expression Inventory-2 (STAXI-2) in Hispanic and Non-Hispanic White Student Samples
This project tested the State-Trait Anger Expression Inventory—2 (STAXI-2) and the Novaco Anger Scale—Provocation Inventory (NAS-PI) in a sample of U.S. Hispanic ( n = 257) and U.S. non-Hispanic White ( n = 246) undergraduate students. Internal consistency, subscale correlations, convergent validity with the Multidimensional Anger Inventory (MAI), and predictive validity were all analyzed. Across ethnic groups, all major subscales demonstrated ad…
Examining Drinking Consequences and Reasons for Drinking in a Bilingual College Sample
College drinking behavior is a national public health concern. However, little research has been conducted to test the psychometric validity and reliability of alcohol use measures among Spanish-speaking Hispanic college students. Adopting a translation-back-translation approach, the Rutgers Alcohol Problem Index (RAPI) was translated into Spanish and the Razones del Consumo de Alcohol (RCA), a newly created measure of one’s reasons for drinking,…
A Confirmatory Factor Analysis of the Attitudes Toward Lesbians and Gay Men (ATLG) Measure
The Attitudes Toward Lesbians and Gay men (ATLG; Herek, 1988) hypothesizes that individuals can have feelings of sexual prejudice toward gay men and lesbians. No research has confirmed the hypothesized factor structure of the ATLG. This study tested four possible factor structures for the ATLG. Results indicate that the hierarchical factor model provided a good description of the ATLG items. A measure of total sexual prejudice was derived. From t…
Clinical and statistical prediction after 50 years
Random error reduction in analytic hierarchies
The principle of ‘divide and conquer’ (DAC) suggests that complex decision problems should be decomposed into smaller, more manageable parts, and that these parts should be logically aggregated to derive an overall value for each alternative. Decompositional procedures have been contrasted with holistic evaluations that require decision makers to simultaneously consider all the relevant attributes of the alternatives under consideration (Fischer,…
Examining the Effectiveness of a Community‐Based Self‐Help Program to Increase Women's Readiness for Smoking Cessation
This study investigated the effectiveness of two components of a smoking cessation intervention: a reading manual and a series of televised programs. Female smokers in the Chicago metropolitan area with a high school education or less were interviewed at 4 different times: baseline, immediate postintervention, and 6 and 12 months. We examined the effects of several baseline measures (race, age, number of cigarettes smoked, and stage of readiness …
Changes in Self-Efficacy and Readiness for Smoking Cessation among Women with High School or Less Education
The most common theory of smoking cessation postulates that readiness to quit begins with changes in attitudes that move the smoker toward behavioral change and eventual cessation. However, trends in smoking indicate that many who currently smoke are not ready to quit. Hence, strategies that both enhance readiness and focus on quitting are likely to be most effective. We hypothesize that an intervention addressed to motivating behavior change wil…
Using Graphical Methods in Assessing Measurement Invariance in Inventory Data
Most measurements of psychological constructs are performed using inventories or tests in which it is assumed that the observed interdependencies among the item responses are accounted for by a set of unobserved variables representing the psychological constructs being measured. Using test scores, researchers often attempt to detect and describe differences among groups to draw inferences about actual differences in the psychological constructs m…
Disparate WTA-WTP disparities
A host of studies have shown that respondents typically provide larger values reflecting their willingness to accept compensation (WTA) for the loss of a product than amounts they would be willing to pay (WTP) to acquire the same product (Knetsch and Sniden, 1984; Cummings, Brookshire, and Schulze, 1986; Irwin, 1994). Meanwhile, other evidence indicates that causes for the deterioration or the damage of a product (either human or natural) will in…
