Ethnicity, substance use, and development: exemplars for exploring group differences and similarities.

Epidemiological research shows some ethnic-group differences in the prevalence of substance use. This approach does not address the question of whether there are ethnic-group differences in the models that are needed to understand the development of substance use. For this question we need to understand the relations between psychological constructs and their trajectories over time. In this paper we describe some approaches to studying ethnic-group differences in the predictors of substance use that illustrate probing for mediators, multisample analyses of structural models, and an experimental trial of a preventive intervention. Our studies found some ethnic-group differences in the structure of constructs and the relations between variables, but many similarities. The challenge for researchers is using appropriate research methods for studying ethnicity, uncovering the basis for ethnic-group differences when they occur, knowing when statistical differences are meaningful, and acknowledging when developmental models are comparable.

Acculturation and cervical cancer: knowledge, beliefs, and behaviors of Hispanic women.

In a community-based sample of Hispanic women, this study examines differences in relation to level of acculturation in knowledge about the Pap examination, fear/fatalism towards cancer, and cervical cancer screening behaviors. Respondents were randomly chosen from 11 churches in the Phoenix metropolitan area (n = 566) and were categorized into three acculturation levels: low (35.2%), bicultural (26.3%), and high (38.5%). Interviews focused on family history of cancer as well as knowledge about cancer and utilization of screening techniques for breast and cervical cancers. OLS regression and probit analyses were conducted to examine the role of acculturation in differentiating. Hispanic subgroups in relation to knowledge, beliefs, and behaviors regarding cervical cancer. Findings of the present study indicate that Hispanic women in the Phoenix metropolitan area are utilizing cervical cancer screening services with over 90 percent of women in all three acculturation groups ever having had a Pap exam and more than 50 percent having had the examination during the past year. However, results also indicate that of the Hispanic subgroups examined, lower acculturated Hispanic women have less knowledge about Pap smears and exhibit lower utilization rates for cervical cancer screening. These results suggest that lower-acculturated Hispanic women comprise the subgroup of Hispanics that is at greatest risk of presenting with advanced stages of cervical cancer. Results have implications for cancer screening and education programs for Hispanic women as well as implications for health care professionals who serve this population.

Risk-taking and abusive behaviors among ethnic minorities.

The health status and health outcomes of many ethnic minorities have remained poor, or have deteriorated, despite massive health promotion campaigns. Multiple factors that encourage ethnic minorities to engage in high-risk behaviors and those that discourage health promotive behaviors must be closely examined before any health interventions are likely to be successful in decreasing substance abuse, high-risk sex, accidental deaths and injuries, and violence. Cultural and contextual factors may put some ethnic minorities in jeopardy and at higher risk for poorer health than their White counterparts (B. W. K. Yee, 1995, in press). This review article identifies contributing factors in high-risk behaviors and highlights research gaps for Americans of African, Indian, Asian and Pacific Islander, and Hispanic descent.

Cancer risk reduction in Mexican American women: the role of acculturation, education, and health risk factors.

This article describes a two-factor schema for the development of culturally appropriate cancer risk reduction interventions for Mexican American women. Regarding this approach, risk factors for two major cancer areas are reviewed: cigarette smoking and obesity/diet. We first describe a schema that facilitates the planning of strategies associated with preferred health interventions and preventive approaches for cancer risk reduction with Mexican American and other Latino/Hispanic persons. This schema examines Acculturation and Education as key factors that should be considered in developing health education messages and interventions that are culturally and educationally appropriate to the identified subpopulations of Hispanics in terms of language and informational content of the message and in terms of psychological factors related to health behavior change. Empirical data from a community sample is presented for the purpose of illustrating the validity of this schema. Then we review studies that examine the effect of acculturation on the distribution of the risk factors, based on studies in the current literature. Here we note the target group of women with the highest risk, based on the available information on Acculturation and other sociodemographic factors. Additionally, an illustration is presented where information and the concepts offered by the two-factor schema facilitate the analysis of (a) health education message needs and (b) needed behavior change, thus pointing to (c) more appropriate health promotion strategies for targeted Hispanic/Latino individuals or groups. The information described in this article aims to help program planners, researchers, and health educators in the design of more effective programs of health intervention for Mexican American and other Hispanic/Latino women.

Mobilizing churches for health promotion in Latino communities: Compañeros en la Salud.

Compañeros en la Salud (Partners in Health) is a 3-year project funded by the National Cancer Institute to conduct a church-based health promotion program whose aim is to reduce the risk of breast, cervical, and diet-related cancers in Latino/Hispanic women by increasing their knowledge of preventive behaviors, motivating healthy behavior change, and increasing their access to and utilization of preventive health services. From a systems perspective, churches serve as miniature, dynamic communities that present an opportunity for developing and implementing a program of health promotion. An analysis of church, Promotora (peer health worker), and participant characteristics from the preintervention base-line data revealed a naturally occurring segmentation of churches by congregation size and denomination. The Catholic churches almost exclusively were larger, whereas the Protestant churches almost exclusively were smaller. An analysis of the psychosocial characteristics of the various Latino women, when stratified by church congregation size, revealed that the women from the smaller, Protestant churches were poorer, had a lower level of acculturation, and had lower lifetime rates of clinical breast examinations. These results suggested greater resource deficits and a relatively higher need for Promotora outreach services for women from the smaller, Protestant churches. Implications are presented for differential approaches to effective health promotion among various types of churches.

Parental influences to smoke in Latino youth.

BACKGROUND: Latino youth have been found to have a higher prevalence of tobacco use than do other ethnic groups, possibly due to cultural factors and parental influences. METHODS: Seventh-grade students (N = 589) were surveyed in San Diego, California, and Tijuana, Mexico, to assess parental influences to smoke. These parental influence variables were studied with logistic regression, adjusting for age, sex, and number of parents who smoke. RESULTS: Among those whose parents smoke, Mexican students were asked to strike a match to light their parents' cigarettes significantly more often (57%) than Mexican-American students (37%) and U.S. Others (37%) (P < 0.05). Seventeen percent of the Mexican students reported having lit a cigarette in their own mouth for their parents, compared to 18% of Mexican-Americans and only 3% of U.S. Others (P < 0.01). Mexicans reported buying cigarettes for their parents more often (62%), compared with 36% for Mexican-Americans and 30% for U.S. Others (P < 0.01). Child smoking was only associated with friend offers of tobacco and parental prompts to light cigarettes in their mouths. CONCLUSION: Latino parents are inadvertently prompting their children to smoke. Smoking prevention programs targeting Latino youth may need to include a parental tobacco education component.

Breast self-examination: knowledge and practices of Hispanic women in two southwestern metropolitan areas.

The breast self-examination (BSE) practices of 1,453 Hispanic women in Phoenix, Arizona and San Diego, California were the focus of this study. Variables proposed as factors that influence the frequency and proficiency of BSE were demographic variables, particularly language and level of acculturation, having been taught BSE by a health professional, and experience with the disease. Results indicate that even though the majority of the women at both the Phoenix (78.1%) and San Diego (83.7%) sites had been taught BSE by a professional and most women in Phoenix (62.5%) and San Diego (63.4%) reported performing BSE within the past month, only 0.7% of the women at both sites were found to be proficient in the technique of BSE. Further, results indicate that language and acculturation were correlated with whether or not a woman performed BSE. These findings suggest that BSE education classes must provide information and techniques that promote proficiency in BSE, and must be designed to meet the unique needs of Hispanic women, particularly those of low acculturation levels.

Are clinical psychologists prepared for service and research with ethnic minorities? Report of a decade of progress.

Longitudinal data on the status of training of clinical psychologists for service and research with ethnic minority populations were presented in order to assess progress. Data from an earlier survey by Bernal and Padilla (1982), which were collected in 1979-1980, were compared with similar survey data collected in 1990-1991. Results revealed a mixed picture of progress: Key aspects of minority training have improved, and there is a substantial block of programs committed to minority training. However, two changes are needed: engagement in a change process leading to training for cultural competence rather than minimal exposure to culture, and a significant increase in the numbers of minority faculty, which can occur only by a sharp increase in the numbers of minority students admitted into the educational pipeline.

Knowledge and attitudes about AIDS among staff of community-based health and social service organizations in the Southwest: implications for staff training.

To ascertain the specific AIDS training needs of staff from community-based organizations in the Southwest, a survey of knowledge and attitudes was conducted by the National Coalition of Hispanic Health and Human Services Organizations (COSSMHO) in the 5 Southwestern cities of Albuquerque, El Paso, Phoenix, San Diego, and Tucson. The responses of 1057 staff were examined according to staff position: managerial, direct service, clerical, and volunteer. Staff were 60.3% Hispanic/Latino and 28.4% white non-Hispanic. Staff responses were examined on 3 dimensions of AIDS-related knowledge and on 3 attitudinal dimensions. A multivariate analysis of covariance (MANCOVA) that controlled for 4 sources of group nonequivalence revealed generally that managers and direct service staff had higher knowledge and more favorable attitudes than did clerical and volunteer staff. Of greatest concern, however, was the number of specific knowledge items for which all staff obtained less than 80% correct answers. Disturbing knowledge deficits exist on important AIDS-related information across all levels of staff. Specific content and strategies are presented for corrective interventions by staff type.

Differences in cancer-risk-related behaviors in Latino and Anglo adults.

METHODS. Latino (n = 358) and Anglo (n = 113) adults living in the San Diego area were surveyed on nutrition, smoking, and cancer screening behaviors. The Latino respondents were dichotomized into a low (L-Latino) or high (H-Latino) acculturation group according to a median split of an acculturation index. RESULTS. After controlling for age, years of education, gender, marital status, and income, significant cross-cultural differences were found in saturated fat/cholesterol avoidance, and fiber and high calorie food consumption. L-Latino respondents had the lowest degree of saturated fat/cholesterol avoidance, followed by H-Latinos and Anglos. A pattern of decreasing consumption with increasing acculturation was observed for fiber and high calorie foods. Significant differences were found among women in the prevalence of Pap smear exams, with L-Latinas having the lowest prevalence of ever and in the past year having had a Pap smear, followed by H-Latinas and Anglos. A similar significant pattern was observed among women 50 years of age or older with respect to the prevalence of ever having had a mammogram.

Cocaine abuse treatment: a review of current strategies.

The treatment of cocaine abusers is a newly emerging discipline. Many of the strategies that are being developed for this purpose have been adapted from the drug and alcoholism treatment systems. These include use of established programs that are only minimally modified for cocaine abusers, such as the 28-day inpatient hospital, therapeutic community, and 12-step programs. Other approaches have created specific techniques to meet particular clinical needs of cocaine abusers, such as behavioral, pharmacologic, and nontraditional interventions. Finally, several attempts have been made to create integrated outpatient approaches that address the multiple needs of the cocaine abusers. Many of the clinical researchers conducting research on these modalities feel optimistic about the value of treatment for cocaine abusers. Many of the methods appear to have considerable promise. However, only recently have well-controlled research efforts begun to provide the information necessary for empirically based decision-making. During the next several years, outcome studies should provide an excellent set of data to guide treatment efforts. This paper reviews the treatment efforts that have been conducted, overviews the research data available, and describes some of the outcome research in progress.

Cigarette smokers do more than just smoke cigarettes.

In this study, we hypothesized that light and moderate-to-heavy cigarette smokers, when compared with nonsmokers, would exhibit significantly less healthy attitudes and behaviors on several dimensions relevant to the risk of coronary heart disease (CHD). A factor analysis of survey items measuring knowledge, attitudes, and behaviors in five CHD risk areas produced four major factors, which we labeled Attitudes (Factor 1), Health Consciousness (Factor 2), Knowledge (Factor 3), and Unhealthy Behaviors (Factor 4). Factor-based scales generated for each of these four factors were used in a one-way multivariate analysis of variance to examine differences between nonsmokers, light smokers, and moderate-to-heavy smokers. Cigarette smokers versus nonsmokers exhibited less positive attitudes toward CHD risk behaviors, whereas moderate-to-heavy cigarette smokers, as compared with the light smokers and the nonsmokers, exhibited lower levels of health consciousness and enacted unhealthy behaviors at a greater frequency. The moderate-to-heavy cigarette smokers also exhibited a lower commitment to enact healthy behavioral changes in the immediate future, even after corrections were introduced for their lower frequency of healthy behaviors during the past week. Overall, these results support our hypothesis that cigarette smokers, particularly as they become more involved with cigarette smoking, do more than just smoke cigarettes; they exhibit a less healthy lifestyle as shown by cognitive, behavioral, and motivational dimensions related to cardiovascular health.
