Brief summary

In the United States, Black women are more likely to die of cervical cancer than White women. In developing countries and globally, Haitian immigrant women are more likely to die of cervical cancer than any other women in the world. Studies have shown a disparity in parental acceptance of the HPV vaccine with parents of Black adolescent girls being less likely to accept and comply with HPV immunization schedules than Whites. The objective of this study is to increase HPV immunization rates in Haitian and African American adolescent girls. The investigator's hypothesis is that a validated behavior change mechanism, brief-negotiating interviewing (BNI), will effectively increase the proportion of mothers who give consent for their daughters' HPV vaccine, which will ultimately lead to higher vaccination rates, and increase knowledge of HPV infection and the vaccine in Haitian immigrant and African American mothers.

Detailed description

In the U.S., Black women have higher rates of cervical cancer than White women. Women in Haiti and Haitian immigrant women have among the highest rates of cervical cancer in the world. The recent introduction of the HPV vaccine provides an opportunity to reduce the disparity in cervical cancer rates between White and Black non-White (Haitians and US born African-Americans (AA)). Unfortunately, females ages 11-14 have low rates, 25%, of HPV vaccination. For the vaccine to be effective it must be given prior to the onset of sexual activity. Parents are a central audience for interventions to promote HPV vaccine uptake in children \< 18 since parents have to consent. Hypothesis: The objective of this study is to increase HPV immunization rates in Haitian and African American adolescent girls. My hypothesis is that a validated behavior change mechanism, brief-negotiating interviewing (BNI), will effectively increase the proportion of mothers who give consent for their daughters' HPV vaccine, which will ultimately lead to higher vaccination rates, and increase knowledge of HPV infection and the vaccine in Haitian immigrant and African American mothers. Specific Aim 1a: Develop a script that will use BNI to address low-income Haitian immigrant and African American mothers' concern about HPV immunization Specific Aim 1b: Teach community health workers to use BNI to enhance HPV acceptability Specific aim 2: Conduct a pilot, randomized clinical trial to determine feasibility effectiveness of BNI, and to obtain empirical estimates of study parameters to assess logistical aspects of a larger Randomized Clinical Trial (RCT). This will include assessing recruitment and retention of subjects, intervention delivery, and effect size. Study design: The primary study design will be a RCT which will follow the CONSORT requirements for data reporting and analysis. One-hundred immigrant Haitian mothers bringing their adolescent daughters (age range 11 to 15) to clinic for routine care will be randomized to BNI (n=80) or to standard care (N=80) information about HPV vaccine). The primary outcome will be receipt of the first HPV vaccination in the adolescent within 1 month of randomization. The secondary outcome will be maternal knowledge about HPV vaccine. This study will provide key estimates so that we can conduct a fully-powered RCT, which will include completion of the primary HPV series (3 vaccinations) as the primary outcome.

Participant flow

Recruitment details

We recruited 100 English- and 100 Haitian Creole-speaking mothers of adolescent girls between April 2011 and September 2013 at the medical clinic ( pediatrics and adolescent clinic). Of 1,703 mothers approached during the study period,1,201 were ineligible. Of the 502 eligible, 302 declined and 200 (40%) were recruited &consented to pilot trial.

Pre-assignment details

Following participant enrollment, but prior to group assignment, no significant event occurred. However, in our study after being randomized, participants provided demographic data. During data collection, one participants was excluded/self-withdrew from the trial for fear that demographic data may affect her immigration status/not documented.

Standard of Care
A clinical Pilot trials of a Brief Negotiated Intervention (a brief modified version of Motivational interview using a client-centered style) with mothers to improve HPV vaccination in Haitian and African-American adolescent daughters/girls compare to standard of care. Of the 100 women in the Control Group (n=50 Haitian, 50 African-American), three African-American mothers did not complete Control Group activities because they did not complete the survey. Reasons for initial dropout/decline to participate included being too busy, not interested, time constraints, and daughter not sexually active upon hearing study has to do with HPV vaccine.
100
BNI/Intervention
One hundred mothers received intervention (n=50 Haitian, 50 African-American). Four Haitian mothers did not receive intervention because (i) One was called to see the clinical provider during the intervention and did not return (n=1), and (ii) time constraints (n=2), one for immigration status .
