Methods Core Seminars

Upcoming seminars

This announcement is for our rescheduled seminar (originally scheduled for April 27, 2018).

This August, the Methods Core invites Sam Dilworth and Dee Chakravarty to present a discussion covering the survey software products Qualtrics and REDCap; these products are free to UCSF employees and could be the answer to your data collection needs! In preparation for their seminar, they have crafted a brief online survey, where they hope to hear about your experiences with one or both of these products; it shouldn’t take more than 5 minutes to complete and your input is greatly appreciated!! The link to their short survey is here: short survey

Title:  To ‘Qualtrics’ or to ‘REDCap’? That is the question…

Presenters:  Samantha E. Dilworth, M.S. and Deepalika Chakravarty, M.S.

Center for AIDS Prevention Studies (CAPS)

Department of Medicine, UCSF

Date and Time: Tuesday, August 28, 2018, 12:00 noon– 2:00 pm

Location: AmFAR Conference room, MH-3700 , 550 16th Street (at 4th Street), 3rd Floor, Mission Bay, SF 94158

Abstract:  As part of the MyResearch suite of applications, UCSF has made available two different online survey software packages: Qualtrics and Research Electronic Data Capture (REDCap). These applications are available to the UCSF Research Community and its collaborators at no extra cost. This talk will present an overview and comparison of these two applications by using examples of their real life implementation in research projects. Topics will include primary features, benefits, shortcomings, and IT-support options. The goal is to enable investigators and data analysis personnel to decide if one or both of these tools can be useful for their research studies. 


Sam Dilworth is a long-time CAPS statistician/data manager, having worked on a wide array of projects at CAPS and SFGH. Her adventures in HIV-prevention research run the gamut, from studies on a cohort of homeless women, to harm-reduction among meth-using MSM, to longitudinal research with gay couples. As a data manager, she has extensive experience with programming surveys, maintaining databases for, and producing analysis-ready datasets from multiple data collection/survey software packages, including Qualtrics, RedCAP, QDS, CASIC, and Survey Monkey. Her statistical qualifications afford her the benefit of knowing how best to capture the data in terms of how it is needed for data quality, precision, and analysis. She has consulted with and advised other researchers on survey software solutions; created protocols for survey testing, data collection, and data management; and is driven to find, master, and apply the best survey software available for the needs of the study.

Ms. Chakravarty is a biostatistician at CAPS experienced in survey programming, survey data management and statistical analyses of HIV related data from diverse populations. She has been the statistician and data manager on numerous longitudinal studies including multi-site HRSA-funded demonstration studies as well as NIMH-funded studies on gay couples. She has programmed and managed surveys for Computer Assisted Survey Instrument (CASI) administration using QDS, REDCap and Qualtrics. She has created databases to facilitate the day-to-day recruitment tracking and similar administrative aspects of longitudinal dyadic studies. She has also developed data collection and data management protocols, trained appropriate personnel and supervised data collection. RSVP to Estie Hudes.
