An interventional study of CHOICES and eBook in Sickle Cell Disease and Sickle Cell Trait, sponsored by University of Florida. Active, not recruiting at 1 site in United States. Open to participants aged 18 Years to 45 Years. Per ClinicalTrials.gov, last updated 2026-10-23.
Sponsored by University of Florida · Not applicable, Interventional, and Prevention
The study will use web-based data collection (SCKnowIQ) and intervention delivery strategies enhanced by nudges and tailored boosters in a sample of 430 adult men and women, aged 18-45 yr with SCD (Sickle Cell Disease) or SCT (Sickle Cell Trait), at-risk, and planning within 2 years to have a child free of SCD.
In a 2-year, randomized, longitudinal, repeated measures, controlled trial in 430 at-risk young adults with SCD (50%) or SCT (50%) to compare the effects of e-Book (electronic-Book) and CHOICES interventions on knowledge and behaviors across time (baseline, immediate posttest, 6, 12, 18, 24 months). The study will provide boosters tailored to knowledge deficits at 6 and 12 months and add monthly reinforcement nudges toward concordant behavior during the first 12 months.

Experimental arm: receives the web-based reproductive education for individuals with sickle cell disease or sickle cell trait
Other: CHOICES
Control arm with eBook education focused on sickle cell disease and sickle cell trait.
Other: eBook
An innovative web application to provide interactive information about reproductive health options for people with SCD or SCT. CHOICES is a multimedia intervention that provides targeted and tailored information for participants to become informed ns about their reproductive health options. Targeted to their sex and tailored to their SC reproductive health knowledge, reproductive health behavior during the previous 6 mo, and parenting plan (e.g., intention to have child with SCD or not), CHOICES presents information about options to help the participant achieve their parenting plan through reproductive partner selection based on sickle cell status, prenatal testing, ovum and sperm donation, advanced reproductive technologies, and options to avoid pregnancy or adopt. The website will be housed on secure University of Florida (UF) servers and accessible via computers or mobile devices (e.g., tablets, smart phones); device capture will inform plans for long-term dissemination.
e-Book contains information typically shared in clinical SCD care, including stick figure representation of inheritance because the investigator considers it unethical to withhold this basic information. It does not include other information related to the SCKnowIQ knowledge items or any of the behaviors needed to implement a parenting plan. Although not as long as CHOICES, the e-Book is sufficiently long, attractive, and engaging to retain participants randomized to the usual care control group; key factors for an adequate control condition. Interestingly, during the study and in interviews after the study, many e-Book participants commented that they were pleased to be assigned to the intervention group (they had not), which indicates that the control condition is sufficient for its intent--2-yr longitudinal retention of the sample. Also, human contact is the same for both groups, and the time-on-task on the computer is unlikely to influence study knowledge and behavior endpoints.
Sickle Cell Reproductive Health Knowledge
Knowledge. The Sickle Cell Reproductive Health Knowledge Questionnaire measures knowledge of the genetic transmission of SCD and SCT, etiology of SCD, parenting options for people with SCD or SCT, types of contraceptives safe for people with SCD or SCT, and risks of complications during pregnancy for the woman with SCD. Responses are multiple choice options. Scores are totaled across all items, ranging from 0 to 17; higher scores reflect better knowledge than lower scores.
Time frame: Baseline up to 24 months
Plan to share: No
