Clinical trials-related knowledge, attitudes, and behaviors among Black and Latina women: A randomized controlled trial of the Women United: Clinical Trials and the Fight Against Breast Cancer Program.

Black and Latino adult cancer patients are underrepresented in cancer clinical trials, which limits generalizability of findings and amplifies disparities in healthcare access and outcomes. Community-level education programs designed to address barriers to participation could improve representation in cancer clinical trials. Through a community-campus partner framework, this study evaluated the Women United: Clinical Trials and the Fight Against Breast Cancer Program in Spanish and English. Participants were 422 women (141 Black, 140 Latina Spanish preference, 141 Latina English preference) who were randomized to view either the intervention (n = 215) or a control (n = 207) program. Assessments of clinical trials knowledge and barriers to clinical trials participation were taken before and after viewing. Results suggested that clinical trials knowledge increased and perceived barriers to participation decreased for those who viewed the educational program. More specifically, those in the intervention condition perceived fewer barriers related to personal benefits, mistrust, and familiarity of clinical trials. As expected, there were no differences in perceived barriers related to community support for either condition. Participants in both conditions were equally likely to join a subsequent study or a clinical trials community ambassador program. There were no differences in any of the outcomes across ethnicity or language, suggesting the program works equivalently across groups. This program is easy to administer and can be recommended for use among Black and Latina women to address factors related to clinical trials participation.

Is religiosity related to attitudes toward clinical trials participation?

Research indicates that a low percentage of cancer patients enroll in cancer clinical trials. This is especially true among minority groups such as Hispanic Americans. Considering the importance of religion in the Hispanic American community, it is important to understand its relationship to perceptions of clinical trials. Five hundred and three Latina women completed the Barriers to Clinical Trials Participation Scale and the Duke University Religion Index. For the total sample, higher organizational and intrinsic religiosity was significantly associated with a perceived lack of community support for clinical trials participation. In subgroup analysis, the relationship between organizational religiosity and lack of support was stronger among Latinas who were Spanish language preferred and Latinas who were Catholic. Intrinsic religiosity was associated with mistrust among Spanish language-preferred Latinas, and both organizational and intrinsic religiosities were associated with a lack of familiarity with clinical trials among Christian (non-Catholic) Latinas. These results indicate that religious institutions that serve Latinas may be an effective venue for disseminating clinical trial education programs to improve attitudes toward clinical trials participation.

A multigroup confirmatory factor analysis of the Patient Health Questionnaire-9 among English- and Spanish-speaking Latinas.

Depression is a significant problem for ethnic minorities that remains understudied partly due to a lack of strong measures with established psychometric properties. One screening tool, the Patient Health Questionnaire-9 (PHQ-9), which was developed for use in primary care has also gained popularity in research settings. The reliability and validity of the PHQ-9 has been well established among predominantly Caucasian samples, in addition to many minority groups. However, there is little evidence regarding its utility among Hispanic Americans, a large and growing cultural group in the United States. In this study, we investigated the reliability and structural validity of the PHQ-9 in Hispanic American women. A community sample of 479 Latina women from southern California completed the PHQ-9 in their preferred language of English or Spanish. Cronbach's alphas suggested that there was good internal consistency for both the English- and Spanish-language versions. Structural validity was investigated using multigroup confirmatory factor analysis. Results support a similar one-factor structure with equivalent response patterns and variances among English- and Spanish-speaking Latinas. These results suggest that the PHQ-9 can be used with confidence in both English and Spanish versions to screen Latinas for depression.

Adapting a program to inform African American and Hispanic American women about cancer clinical trials.

The dearth of evidence-based clinical trial education programs may contribute to the under-representation of African American and Hispanic American women in cancer research studies. This study used focus group-derived data from 80 women distributed among eight Spanish- and English-language focus groups. These data guided the researchers' adaptation and refinement of the National Cancer Institute's various clinical trials education programs into a program that was specifically focused on meeting the information needs of minority women and addressing the barriers to study participation that they perceived. A "sisterhood" theme was adopted and woven throughout the presentation.

Adaptation of a Cancer Clinical Trials Education Program for African American and Latina/o Community Members.

The pilot study reported in this article culturally and linguistically adapted an educational intervention to promote cancer clinical trials (CCTs) participation among Latinas/os and African Americans. The single-session slide presentation with embedded videos, originally developed through a campus-community partnership in Southern California, was chosen for adaptation because it was perceived to fit the CORRECT model of innovation (credible, observable, relevant, relatively advantageous, easy to understand, compatible, and testable) and because of the potential to customize any components not identified as core, allowing them to be revised for cultural and linguistic alignment in New York City. Most of the 143 community participants (76.2%) were female; most (54.6%) were older than 59 years. More than half (78.3%) preferred to speak English or were bilingual in English and Spanish. A large proportion (41.3%) had not completed high school. Knowledge and perceived benefits and barriers regarding CCT showed small, though statistically significant, increases. There were no statistically significant group differences for changes in mean knowledge, perceived benefits, or perceived barriers when examined by ethnicity, education level, language, or other included sociodemographic variables. However, a small, but statistically significant difference in perceived barriers was observed when examined by country of origin, with the foreign born score worsening 0.08 points (SD = 0.47, p = .007) on the 5-point Likert-type scale administered posteducation compared to preeducation. Participants' open-ended comments demonstrated the acceptability of the topic and intervention. This adaptation resulted in an intervention with the potential to educate African American and Latina/o general community members in a new geographic region about the purpose, methods, and benefits of CCTs.

Health care access and breast cancer screening among Latinas along the California-Mexican border.

Latinas are more likely to exhibit late stage breast cancers at the time of diagnosis and have lower survival rates compared to white women. A contributing factor may be that Latinas have lower rates of mammography screening. This study was guided by the Behavioral Model of Health Services Use to examine factors associated with mammography screening utilization among middle-aged Latinas. An academic-community health center partnership collected data from community-based sample of 208 Latinas 40 years and older in the San Diego County who completed measures assessing psychosocial factors, health care access, and recent mammography screening. Results showed that 84.6 % had ever had a mammogram and 76.2 % of women had received a mammogram in the past 2 years. Characteristics associated with mammography screening adherence included a lower acculturation (OR 3.663) a recent physician visit in the past year (OR 6.304), and a greater confidence in filling out medical forms (OR 1.743), adjusting for covariates. Results demonstrate that an annual physical examination was the strongest predictor of recent breast cancer screening. Findings suggest that in this community, improving access to care among English-speaking Latinas and addressing health literacy issues are essential for promoting breast cancer screening utilization.
