About this study
The Decisional Capacity and Informed Consent in Fragile X Syndrome (FXS) project is for the Eunice Kennedy Shriver National Institute of Child Health \& Human Development, 1R01HD071987-01A1, and will provide the first comprehensive description of decisional capacity of individuals with FXS; identify individual, family, and experiential factors associated with variability in decisional capacity; determine the validity of caregiver and expert ratings; and develop evidence-based guidelines for categorizing decisional capacity of individuals with FXS. The researchers will develop a methodologically rigorous and conceptually grounded decision aid using digital technology to enhance participation of individuals with FXS in the consent process.
Read the detailed description
FXS is the most common inherited form of intellectual disability (ID). The typical male has an IQ (intelligence quotient) of 50 to 55, but involvement ranges from mild to severe. Females are generally less affected and have a broader range in function. Some have severe ID and adaptive impairments, but most have a normal or borderline intellectual ability. This wide range in cognitive skills leads to variable ability to make choices and live independently. Most research on individuals with FXS has been noninvasive, limited to parent surveys and psychological assessments. Studies such as these evoke few if any major ethical concerns, so the consent process typically involves a straightforward parental consent. Some studies have drawn blood, collected saliva, measured heart rate, or used neuroimaging, but until recently there has been a paucity of treatment research. This scenario has changed dramatically in the past several years. Advances in understanding the molecular basis of FXS have led to a new generation of treatments, and clinical trials are under way using a variety of compounds. The possibility of side effects and the potential for significant changes in behavior and ability elevate to a new level the importance of obtaining meaningful consent, not only from parents, but also from individuals with FXS. Researchers and Institutional Review Board (IRB) members need data to guide decisions about involving individuals with FXS in the consent process. Unfortunately, little is known about the extent to which individuals with FXS can be or are involved in decisions about research participation. This project will assess the range of decisional capacity in FXS, identify factors associated with individual differences in decisional capacity, validate a rating scale for categorizing decisional capacity, and develop a novel tablet-based decision aid technology to assist researchers and clinicians in maximizing decisional capacity and consent. This study will work toward achieving two overarching aims: 1) Characterize and explain individual differences in decisional capacity in FXS, 2) Design and evaluate the effect of a tablet-based decision aid on participation in the consent process for a hypothetical clinical trial. Ultimately, this study will provide important information about the nature of decisional capacity in FXS and validate a novel intervention to maximize successful participation in the consent process.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Paper and Pencil Informed ConsentOther
Paper-based informed consent form will be sent to participant and family before data collection visit. They will be able to review as many times as they wish before visit. During visits, simplified overview of informed consent form will be provided in person just once. For MacArthur Competence Assessment Tool (MacCAT) Questions, All questions will be asked after the disclosure information has been presented. Questions will have the same wording as experimental condition. Procedures will mimic MacCAT/flipchart (incorrect or partial credit will be given opportunity to answer question again after disclosure information is repeated). There will be multiple choice options rather than open-ended. Finally, data collection will be done through paper and pencil.
Digital Informed Consent ToolOther
Paper informed consent form will be sent to participant and family before data collection visit. They will be able to review as many times as they wish before visit. During visits, the participant can go through the tablet-based tool up to 3 times. All questions will be embedded within the vignettes/presentation of disclosure information. Question will use simplified wording, similar to flipchart. Procedures will mimic MacArthur Competence Assessment Tool (MacCAT) /flipchart (incorrect or partial credit will be given opportunity to answer question again after disclosure information is repeated). Multiple choice options will be utilized rather than open-ended. Finally, response data stored within tool and exported to dataset for analysis.

What is being measured
The primary outcome is the main question the study is designed to answer.
Decisional Capacity - Understanding Score
MacArthur Decisional Capacity - understanding score, range 0 (no understanding) to 26 (perfect understanding) A summary score was calculated, ranging from 0-26. Scores were then translated into a percentage based on the number of questions answered. A score of 100% indicates that the participant answered each understanding question correctly on the first attempt.
Measured: Day 1, immediately following presentation of the material in the intervention or comparison condition

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 Dec 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Decisional Capacity - Understanding Score (time frame: Day 1, immediately following presentation of the material in the intervention or comparison condition). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02465931, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Mar 2019.
