Introduction and Purpose
In the Consumer Expenditure Diary Survey (CED), respondents are asked to complete two, one-week diaries in which they record purchases made by their household during that week. The CED and its companion survey the Consumer Expenditure Interview Survey have experienced declining response rates and concerns about measurement error. One recommendation that has been made for addressing these issues in the CED is to provide respondents with the option to record their purchases through a web-based instrument, which presents a number of benefits over paper diaries. An electronic diary was developed for this purpose.
Through several recent usability and field tests, the electronic diary has demonstrated potential, but also some limitations. Participants in usability tests often enter purchases at a higher level of aggregation than is desired for classification (e.g., they enter “groceries” when we need them to enter “milk,” “eggs,” “bread,” etc.). In field tests, response rates for the electronic diary are consistently lower than they are for the paper diary. Also, respondents enter fewer items in the electronic diary than the paper diary.
Due to time and resource constraints prior to a recent field test, some ideas that were suggested for the desktop version of the electronic diary were not explored and implemented. In order to progress towards the improvement and exploration of more options for the electronic diary, the Division of Consumer Expenditure Surveys (DCES) at the Bureau of Labor Statistics obtained the services of a contractor to develop and usability test electronic diary improvements for the desktop version for use in an upcoming field test.
The objectives of this study are to:
Conduct usability testing on two, newly designed CE electronic diary instruments, to ensure that respondents are able to properly use the diaries.
Provide a recommendation for which design to implement and changes to make in the future.
2. Research Design
Participants will come to the usability research lab at the Westat facility in Rockville, MD. The testing will take place in a usability testing room with a facilitator and a computer that has software to record the actions in the internet browser. This recording will capture the participants’ interaction with the two prototype electronic diaries as well as the participants’ and facilitator’s voices. Observers will monitor the session from an adjacent room.
The session facilitator will begin by introducing the purpose of the study (Appendix A) and obtaining informed consent (see Appendix E for informed consent document). The facilitator will then describe the basic functions of the diary as well as the information we would like the participant to record. The facilitator will then ask respondents to complete 6 tasks using one version of the diary (see Appendix C for diary screenshots). The tasks will consist of asking the participant to enter, edit, and delete expenses using a mixture of expenses from their own experience and fake expenses created for this study (see Appendix B for the protocol). Participants will be encouraged to think aloud while completing the tasks. Following each task, participants will be asked to rate the ease or difficulty of the task using a seven-point scale ranging from “Very Difficult” to “Very Easy.” The facilitator will verbally ask for the rating after each task and record each participant’s responses. After working through the 6 tasks, the facilitator will ask several follow-up questions about that version of the diary (see Appendix B).
The facilitator will then walk the participant through the second version of the diary and ask them to complete 6 tasks with this version (see Appendix C). These tasks will be similar to those used with the first version, but covering different expenditures. The facilitator will then ask follow-up questions specific to that diary (see Appendix B). The order of the two diaries will be counterbalanced so that 15 participants will receive Version 1 first and then 2 and the other half will receive Version 2 first and then 1.
After the participant has completed tasks with both diaries, the facilitator will ask questions about their overall experience with the diaries, including the participants’ preference for one or the other. Finally, the facilitator will follow-up with the participant about any data entry problems he/she had with either diary. Due to the exploratory nature of this research, the facilitator may ask questions that are not listed in Appendix B. These questions will generally be directed at asking the participant to explain their thought processes (e.g., “I see that you ___. Can you tell me more about that.”) or to expand upon an answer given to a debriefing question.
Participants’ success or failure at each task and any problems they had while completing the tasks will be noted by observers according to the following two ratings: fully successful or not successful. A participant is ‘fully successful’ in completing a task when he or she completes the stated task as intended with no help from the facilitator. For tasks that require the entry of expenses into the diary (including multiple expense tasks), this rating should only be given if all information is entered correctly. That is, the correct date, price, and category. The description should give enough information to place it into a CE-relevant category and category-specific questions should also be answered correctly. A participant is ‘not successful’ when he or she does not complete the task as intended or can only do so after asking the facilitator for assistance (though the participant can consult help materials). For tasks that require the entry of expenses into the diary, the rating of ‘not successful’ should be given if the participant enters unusable data. For example, if a participant enters a full receipt as a single entry (when item level detail is required) or if the participant enters the description of an item that is insufficient to classify it into a CE-relevant category. The entry of incorrect information should also be rated as ‘not successful.’ For tasks that require the editing of expenses, the rating should be given if the participant alters the data in a way other than intended. For example, if a participant completes the “Delete Shirt” task by removing the cost and resaving the expense.
3. Participants
Westat will recruit 30 participants from a Westat-maintained participant database and responses to an advertisement posted on Craigslist (see Appendix F). Westat will seek to balance the number of participants with characteristics associated with level of household spending; education, income, and household size. Potential participants will be screened using the script in Appendix D.
4. Burden Hours
The total estimated burden hours for this study is 33. Our goal is to obtain feedback from 30 participants. We anticipate that each session will approximately one hour for a total of 30 burden hours. Screening potential participants from the Westat database is estimated to take an additional 5 minutes per participant (see Appendix D for recruitment script). Given that participants are being recruited from the Westat database, we expect a high acceptance rate. We estimate the total burden of recruitment to be 3 hours (40 potential participants X 5 min.).

Appendix A: Introduction
Thank you for coming in today. Let me tell you a little about Westat and what we’re going to do today.
Westat is a company that conducts research on many topics, for different organizations. This particular project is for the Bureau of Labor Statistics. The Bureau of Labor Statistics conducts a study every year that asks people to record all of the purchases that all members of their household get for an entire week. Westat has been asked to test some different procedures to make it easier for people to report what they purchase. For this task today we will be asking you to record some expenses on the computer. Some of the expenses you will be entering will be on receipts that we have created for you and other times you will enter expenses from the receipts that you brought with you today. Your participation today will help us design a better system for people to enter their purchases in this study.
At this stage we are still developing the study procedures and figuring out how to make it as easy as possible for people to record their purchases. So that is what you’ll be helping us with here today. Do you have any questions about that?
Before we get started, I want to let you know that everything we cover in the interview will be kept private - only the few people actually working on the project will have access to the information you share with us. If there are any questions you don’t want to answer that is perfectly fine - We’re really more interested in how the questions we ask and tools we are using work.
If it’s OK with you, I would like to video record our conversation, just so that I can review it later when we’re analyzing all the interview data. (And finally, some of our colleagues from the Bureau of Labor Statistics are here today – behind the mirror - to observe and see for themselves how the study is going.)
CONSENT FORM: Here is a form I must ask you to look over and sign – it basically covers the points I’ve just gone over with you and indicates you have agreed to take part (ONE COPY FOR RESPONDENT, ONE COPY FOR US)
BEGIN INTERVIEW:
