Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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.

Comparison Condition

OTHER

Paper and pencil informed consent

Other: Paper and Pencil Informed Consent

Intervention condition

EXPERIMENTAL

Digital informed consent tool

Other: Digital Informed Consent Tool

Interventions

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.

Comparison Condition

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.
