CLSA Core Study

CLSA web-based questionnaires offer a flexible and user-friendly interface that accommodates the varying technological proficiencies of participants, ensuring a seamless and inclusive data collection process.

Web-based questionnaires play a pivotal role in gathering supplemental information that enriches the CLSA. Beginning in Follow-up 3, a 30-minute web-based survey was introduced to collect information on family history of disease and sexual health from all participants. Participants without internet access are provided with the option to take part by telephone.

Despite an aging population, little is known about the sexuality of older adults. The purpose of this survey is to collect information about healthy sexuality in our population. The questions in the module are based on a review of sexual health questionnaires from the English Longitudinal Study on Ageing, the Irish Longitudinal Study on Ageing, the National Social Life, Health, and Aging Project, and the National Institutes of Health’s Patient-Reported Outcomes Measurement Information System®.
