Validity and Reliability of the Korean Version of Assessment of Health Literacy in Breast and Cervical Cancer Screening

Health literacy is a significant determinant of health and health behaviors such as cancer screening. Despite its significance, there are limited instruments available to assess health literacy targeting Koreans. The purpose of this study was to test the psychometric properties of Korean translation of a validated health literacy instrument in cancer screening-Korean version of assessment of health literacy in breast and cervical cancer screening (K-AHL-C). A total of 555 women aged 20~65 participated in the online survey study. Of 52 items addressing five domains included in the original version, we focused on 36 items addressing three key domains closely associated with cancer screening: familiarity, health navigation, and comprehension. During content validation, two items from the health navigation domain were removed, yielding 34 items. Using Rasch analysis and confirmatory factor analysis, we found the evidence of construct validity of K-AHL-C. The Korean version was also significantly correlated with measures of Functional Health Literacy scale, cancer prevention behaviors, and subjective health status, suggesting convergent validities respectively. Finally, K-AHL-C had acceptable reliability coefficients (α) ranging from 0.71 to 0.92 for each domain and the total scale. These psychometric properties support the K-AHL-C is a valid and reliable instrument for measuring Koreans' health literacy in cancer screening. Also it is expected to use the instrument to detect breast and cervical cancer early and improve the screening rate, and ultimately to contribute to the promotion of women's health and women's health nursing practice.

Community‐based health literacy focused intervention for cervical cancer control among Black women living with human immunodeficiency virus: A randomized pilot trial

AbstractBackgroundHealth literacy plays an essential role in how individuals process health information to make decisions about health behaviours including cancer screening. Research is scarce to address health literacy as a strategy to improve cancer screening participation among women living with human immunodeficiency virus (HIV), particularly Black women who, despite the heavy burden of cervical cancer, report consistently low screening rates.AimTo assess the feasibility, acceptability and preliminary efficacy of a health literacy‐focused intervention called CHECC‐uP—Community‐based, HEalth literacy focused intervention for Cervical Cancer control—among women living with HIV.MethodsWe conducted a community‐based, single‐blinded randomized pilot trial. A total of 123 eligible women were enrolled and randomized to one of two conditions, control (i.e., cervical cancer brochure) or intervention (cervical cancer brochure plus 30–60 min health literacy‐focused education followed by monthly phone counselling and navigation assistance for 6 months). Study assessments were done at baseline, 3 and 6 months. The final analysis sample included 58 women who completed all data points and whose Papanicolaou (Pap) test status was confirmed by medical records.ResultsAll intervention participants who completed the programme would recommend the CHECC‐uP to other women living with HIV. However, adherence in the experimental conditions was low (49.6% attrition rate including 20 women who dropped out before the intervention began) due, in large part, to phone disconnection. Those who had received the intervention had a significantly higher Pap test rate compared to women in the control group at 6 months (50% vs. 21.9%, p = .025). Participation in the intervention programme was associated with improved health literacy and other psychosocial outcomes at 3 months but the trend was attenuated at 6 months.ConclusionsThe CHECC‐uP was highly acceptable and led to improved Pap testing rates among Black women living with HIV. Future research should consider addressing social determinants of health such as phone connectivity as part of designing a retention plan targeting low‐income Black women living with HIV.ImplicationsThe findings should be incorporated into a future intervention framework to fulfil the unmet needs of Black women living with HIV to facilitate their decision‐making about Pap test screening.Patient or Public ContributionNineteen community members including women living with HIV along with HIV advocates and care providers participated in four focus groups to develop cervical cancer screening decision‐relevant information and the health literacy intervention. Additionally, a community advisory board was involved to provide guidance in the general design and conduct of the study.

Factors associated with HPV vaccination decision-making among Korean American women

Despite a significant reduction of human papillomavirus (HPV) infection in the United States in the past decade, Korean American (KA) women experience a disproportionately high cervical cancer burden due to low HPV vaccination rates. Given associations between parental decision-making and adolescent vaccination, it is crucial to identify and address factors influencing parental HPV vaccination decision-making for their children. The purpose of this study was to examine the sociodemographic characteristics and health literacy factors in relation to KA women's willingness to allow their daughters to receive HPV vaccination. We used baseline data collected from 560 KA women who participated in a cluster-randomized trial designed to promote mammography and Pap test screening. Participants answered study questionnaires measuring individual characteristics, cancer literacy, HPV knowledge, and HPV vaccination decision-making for their daughters. Multivariate logistic regression analysis was conducted to identify the correlates of HPV vaccination decision-making among participants. Over half of the participants (54%) endorsed HPV vaccination for their daughters. Low knowledge, compared to high and medium HPV knowledge (aOR 3.48, CI 2.01-6.04 and aOR 2.14, CI 1.46-3.12, respectively), were significantly associated with higher odds of participants' intention to vaccinate their daughters. Additionally, in comparison to low cancer literacy, middle-range cancer literacy (aOR 1.70, CI 1.08-2.68) was significantly associated with higher odds of participants' intention to vaccinate their daughters. Misperceptions about cancer and low HPV knowledge among KA women should be considered when providing vaccine counseling and developing interventions to promote cervical health in this population.

Web-Based Delivery of an Effective Church-Based Intervention Program to Promote Cancer Screening (Community-based Health litEracy-focused intervention for breast and cervical Cancer Control) Among Korean Immigrant Women in the United States: Randomized Controlled Trial

Abstract Background Women with limited English proficiency continue experiencing an unequal cancer burden. Non-White immigrant women present with more advanced breast and cervical cancer than non-Hispanic Whites, attributed to significant cultural barriers as well as low health literacy in attempting to navigate the United States health care system for cancer screening. Community-based Health litEracy-focused intervention for breast and cervical Cancer Control (CHECC-uP) was an in-person, community health worker-led intervention, addressing both cultural and health literacy barriers through health literacy education and follow-up counseling with navigation assistance. The in-person program was tested in a large cluster-randomized trial and yielded high efficacy in promoting mammogram and Papanicolaou test screening in Korean-speaking women. With over 90% of Americans now having online access, the in-person program was adapted to web-based delivery. Objective This study aimed to evaluate the feasibility, acceptability, and preliminary efficacy of the web version of the intervention—e-CHECC-uP. Methods A randomized pilot trial was conducted. A total of 40 women were enrolled and randomized (20 per arm). The study intervention consisted of web-based health literacy education followed by phone counseling with navigation assistance. Study assessments were done at baseline, 3 months, and 6 months. The study’s primary outcomes were cancer screening behaviors verified by medical record review. Upon completion of final study assessments, intervention participants were invited to join postintervention interviews. Results In total, 34 women (intervention: n=15; control: n=19) completed the assessment at 6 months, yielding a retention rate of 85%. The intervention participants were highly satisfied with e-CHECC-uP with a median rating of 8 on a 10-point scale. Between-group differences in screening rates were 34.6%, 47.9%, and 37.5%, respectively, for completion of the mammogram, Papanicolaou test, and both at 6 months. Conclusions We achieved a high retention rate and high participant satisfaction. Although the study was not powered for significance testing, the e-CHECC-uP intervention resulted in large group differences across all cancer screening outcomes in the pilot sample. Online technology can help address multiple logistical barriers associated with in-person intervention delivery. Our findings suggest that web-based delivery of CHECC-uP may be used to promote cancer screening among immigrant women with limited English proficiency, as a promising avenue to ultimately reduce health disparities in underserved communities.
