THE DO'S AND DON’TS OF DIARY STUDIES
For the past seven months I was part of the research team on a large-scale project that incorporated two research methods repeated over the course of seven waves of participants. The first method was a hybrid of contextual inquiries and usability testing where researchers went to participants’ homes and watched them interact with hardware and software for a new in-home device. The second method, and the subject I’m discussing today, was a digital diary study, of which I was the lead moderator.
Diary studies will vary from research project to research project but in the context of our work participants were given devices to use in their home and each day, over the course of about a week, they would complete activities with the device and answer questions using an online questionnaire or digital diary tool. The diary portion helped us collect valuable quantitative and qualitative feedback, enabled us to interact with participants in different geographical areas, and helped us to discover how behaviors and attitudes changed over time.
Repeating this over seven months with seven waves of participants allowed us to also iterate on how we administered the diary portion (as well as the in-homes sessions) of this study. That iteration has produced some key “Do’s and Don’ts” of diary studies. Use these to help ensure your research is the most effective it can be.
