I. Introduction and Purpose

The American Time Use Survey (ATUS) has been conducted solely via Computer Assisted Telephone Interviewing (CATI) since the survey began in 2003. ATUS management is considering adding a self-administered, web-based collection tool such that the ATUS would become a mixed-mode, CATI and web-based survey. The ATUS’s reliance on CATI has become a liability in recent years, as people have become less willing to answer their phones and participate in phone-based interviews. Additionally, the COVID-19 pandemic demonstrated the risk associated with ATUS’s dependence on a centralized call center when it closed in mid-March 2020 and ATUS interviews ceased.

The ATUS sample is drawn from households that have completed Wave 8 of the Current Population Survey (CPS). A specific person within the retired CPS household is selected and this person is then assigned a day of the week for an ATUS interview. The core of the ATUS is a 24-hour diary in which interviewers use conversational interviewing methods to elicit information about the activities respondents did on the day before the interview, who they were with, and where they were.

Other time-use surveys around the world have experimented with the use of self-administered web-based diaries, and this option has appealed to certain cohorts of respondents, especially young adults and those who like the flexibility of responding on their own schedule. However, there are challenges unique to the self-administered mode. When describing what they did during the day, respondents could be given the option of entering open-ended descriptions of their activities or, when possible, selecting from a list of predefined activities/categories. Selecting from a list of predefined activities would ease reporting and reduce burden but runs the risk of introducing measurement bias if the list does not fully capture what respondents do and how they verbalize their activities.

The current ATUS Activity Coding Lexicon is a 3-tiered, time-use classification system with 17 first-tier categories and over 300 activity categories.¹ Each of the first-tier categories has two additional levels of detail. Respondents' reported activities are assigned 6-digit activity codes based on this classification system. In the current use of CATI for data collection, interviewers identify some common activities as they are collected during the interview (for example, sleeping, personal care, working) but enter verbatim descriptions of less commonly occurring activities and assign codes to the activities after the interview has been completed.

The ATUS program recognizes that portions of the current coding system are detailed and complex and would be too burdensome for self-coding by untrained respondents. To address this issue, an effort is currently underway to simplify and streamline the lexicon and to revise or eliminate categories (codes) that are infrequently used or have proven to be of little analytical value to data users. The purpose of the research described in this clearance is to cognitively test the revised lexicon to determine how well it holds together conceptually and if additional steps need to be taken to simplify it. As testing progresses, it is likely that small changes will be made to the lexicon.  For example, some existing categories may be renamed, whereas others might be consolidated or reordered.  However, the scope of the content will remain the same. 

II. Methodology

Participants for the proposed testing will be recruited through Amazon’s Mechanical Turk (MTurk)² for both the navigation and card-sorting tasks. The various tests are listed below:

Test	Purpose
Navigation Test 1	How well does an alphabetical ordering of Tier 1 activities work?
Navigation Test 2	How well does ordering Tier 1 activities by frequency of use work?
Navigation Test 3	Focused test of select ATUS tier 1 categories
Navigation Test 4	Impact of adding an “other” category to the Tier 1 categories
Hybrid Card Sort 1	Determine how well exemplars fall into select Tier 1 categories
Hybrid Card Sort 2	Determine how well exemplars fall into select Tier 1 categories

The proposed tests are described in detail in following sections. Each of the tests described will use participants from Amazon’s Mechanical Turk (MTurk).

Screening Survey

To ensure that higher quality MTurk participants are recruited, SurveyMonkey will be used to conduct an initial 2-minute, online survey prior to each test that asks for age, current employment status, number of children under 16 living in the household, and an open-ended question asking for a description of the most recent task that participants completed on MTurk.

Results from this survey will be used to screen participants for the quality of their response. Only participants who have submitted quality data will be allowed to complete the next task, which will be either a navigation task or card-sorting task, depending on the test (see Attachment 5 for the screening instrument). We estimate that 163 people will need to be screened prior to each of the six tests to provide the 125 participants required for each test.

IIA. Navigation Test 1

1. Research Objective

Determine how well the simplified ATUS lexicon works for self-coding of time-use activities. An alphabetical ordering of Tier 1 activities will be used as shown in the Method section that follows.

2. Method

Navigation, or tree testing, will tell us how easily a general population can categorize common time-use activities using the revised ATUS lexicon. A tool called TreeJack will be used to run the navigation test.³ Correctly categorizing descriptions of how people use their time will be a critical step in the completion of a self-administered diary. Navigation testing will help answer the following three questions about the menu:

1. Do the categories make sense to people?

2. Is the content grouped logically?

3. Can people find the category they want easily and quickly? If not, why not? What is distracting or misleading them?

The Tier 1 codes of the revised lexicon are shown in the table below. The complete lexicon is shown in Attachment 1.

Time-use Activity

Caring for and helping children

Caring for and helping adults

Cleaning and repair services for vehicles and the household

Communications, not in-person (phone, video calls, messaging, e-mails, mail)

Driving or other travel

Eating and drinking

Educational activities

Household activities

Haircuts, massages, manicures, or other personal services s

Professional and medical services

Religious and spiritual activities

Shopping

Sleeping and own personal care

Socializing, relaxing, and leisure

Sports, exercise, and recreation

Using government services and participating in civic obligations

Volunteering for an organization

Working and related activities

Attachment 2 lists the 35 time-use activities that will be coded by participants. These activities were selected to test the full lexicon.

3. Participants

125 participants will be recruited through Amazon’s Mechanical Turk (MTurk) service. A general audience of adults (18 or older) will be recruited.

4. Analysis of Navigation Task 1

The following measures will be used to evaluate results from the navigation testing:

• Direct success. This measure is defined as users who read the task and select the right code without trying any incorrect categories.

• Time required for direct success. This is defined as time elapsed from start to end of the task.

• Indirect success. This is defined as users who try different branches within the tree before selecting the correct code.

• Time required for indirect success. This is defined as time elapsed from start to end of the task.

• Failure. This is defined as users who select the wrong code as the final answer.

• Whether the user ever tried the correct Tier 1 category.

• Whether the user selected the correct Tier 1 category but then selected an incorrect code.

• Time required for failure. This is defined as time elapsed from start to end of the task.

• Major Distractors. This identifies which incorrect Tier 1 codes were selected at the start of a task.

• Skip. This is defined as a user who gives up on the task entirely.

5. Instructions

Instructions for the navigation task are shown in Attachment 3.

6. Burden and Costs for Navigation Test 1

As mentioned previously, past experience has shown us that poor quality responses can be a problem using MTurk participants. Therefore, an initial two-minute screening survey will be used to screen MTurk participants to see if they provide quality responses. Respondents to the screening survey will receive 20 cents (10 cents per minute) to complete the screening survey. Including MTurk’s administrative fee of 40%, the total cost per participant for the screening survey will be $0.28. Based on past experience, we estimate that we will need to screen about 163 people to obtain the 125 required for each study.

The actual navigation test is expected to take an average of 20 minutes to complete. MTurk participants will receive $3.00 for participating in this test (15 cents per minute to encourage greater effort). Since MTurk charges a commission fee of 40%, the cost per case for this test will be $4.20. The total cost per participant including the screening survey will be $4.48.

The costs and burden hours are summarized below:

• Burden hours for screening survey = 5.4 hours

• Burden hours for test = 41.7 hours.

• Each MTurk participant will receive $3.00 for completing the navigation task and $0.20 for completing the screener ($3.20 total).

• Total cost per participant = $4.48, including a 40% MTurk administrative fee

These costs per participant and burden hours apply to each of the four navigation tests and two card-sorting tasks since they were designed to take the same amount of time.

IIB. Navigation Test 2

1. Research Objective

Test 2 will investigate whether ordering the menu items by their actual frequency of use in the ATUS Survey results in better, the same, or worse performance compared to the alphabetical ordering used in Navigation Test 1.

2. Method

The Tier 1 codes of the revised lexicon ordered by reported frequency of use in the actual ATUS data are shown in the table below.

Activities Ordered by Frequency of Occurrence in ATUS

Sleeping and own personal care

Driving or other travel

Socializing, relaxing, and leisure

Household activities

Eating and drinking

Caring for and helping children

Caring for and helping adults

Working and related activities

Shopping

Sports, exercise, and recreation

Communications, not in-person (phone, video calls, messaging, e-mails, mail)

Religious and spiritual activities

Volunteering for an organization

Educational activities

Professional and medical services

Personal care services (this had previously been combined with the category above)

Cleaning and repair services for vehicles and the household

Using government services and participating in civic obligations

3. Participants

125 participants will be recruited through Amazon’s Mechanical Turk (MTurk) service. A general audience of adults (18 or older) will be recruited.

4. Instructions

Instructions for this navigation task are shown in Attachment 3.

5. Analysis

The analytical approach described in Navigation Test 1 will be used.

6. Burden and Costs for Navigation Test 2

The same burden and cost estimates apply as for Navigation Test #1.

IIC. Navigation Test 3

1. Research Objective

The purpose of Navigation Test 3 is to focus on time-use activities that occur in a selected set of 2-digit categories. These categories are of special interest to ATUS staff so additional coding descriptions are used.

2. Method

The time-use activities that will be tested are shown in Attachment 4. In addition, 16 other time-use activities will be added based on results from Navigation Tests #1 and #2. The additional activities will allow us to retest different portions of the lexicon.

3. Analysis

The analytical approach described in Navigation Test 1 will be used.

4. Burden and Costs for Navigation Test 3

The same burden and cost estimates apply as for Navigation Test #1.

IID. Navigation Test 4

1. Research Objective

After determining which ordering of the lexicon’s Tier 1 categories works best (alphabetical vs. frequency), a final test will be conducted with the “other” category present at the Tier 1(2-digit level). This test should inform us if including an “other” category at this level affects accuracy.

22. Method

Attachment 2 lists the 35 time-use activities that will be coded by participants.

3. Analysis

The analytical approach described in Navigation Test 1 will be used. The analysis will also focus on which descriptions are assigned the “other” code. This will help identify time-use activities that participants have difficulty assigning codes using the current lexicon. We can also look at results for these more problematic descriptions from Navigation Tests 1 and 2 to find out how accurately these descriptions were coded in those tests.

4. Burden and Costs for Navigation Test 4

The burden and cost estimates are the same as for Test 1.

IIE. Hybrid Card Sorting Tests 1 and 2

1. Research Objective

Card sorting will help determine how well the revised lexicon captures a wide variety of time-use activities. Card sorting will also help identify areas of conceptual confusion, as well as new categories that might be needed.

2. Method

In a hybrid card sorting test, participants sort a list of activities into predefined categories and also have the option of creating and naming new categories if they believe the current set of categories is inadequate.

Because general testing guidelines suggest limiting the number of items to be sorted to between 30 and 60, two hybrid card sorting tests will be used to determine how well the current lexicon categories work. The time-use activities to be sorted will come from the revised coding lexicon (4- and 6-digit examples) as shown in Attachment 2.

3. Test 1 (54 activities)

• Includes categories 1, 2, 3, and 4, 18

  • 01 Sleeping and own personal care (5)

  • 02 Household activities (12)

  • 03 Caring for household children (10)

Caring for and helping household adults (4)

• 04 Caring for nonhousehold children (10)

Caring for nonhousehold adults (9)

• 14 Religious and spiritual activities (3)

• 18 Driving or other travel (1)

4. Test 2 (57 activities)

• Includes categories 5, 6, 7, 8, 9, 10, 11, 12, 13, 16

  • 05 Working and related activities (5)

  • 06 Educational activities (6)

  • 07 Shopping (3)

  • 08 Using professional and personal care services (4)

  • 09 Cleaning and repair services for vehicles and the household (1)

  • 10 Using government services and participating in civic obligations (1)

  • 11 Eating and drinking (1)

  • 12 Socializing, relaxing, and leisure (14)

  • 13 Sports, exercise, and recreation (12)

  • 15 Volunteering for an organization (5)

  • 16 Communications, not in-person (phone, video calls, messaging, and e-

mails) (5)

5. Analysis

Card sorting is useful for discovering how people expect to see information categorized and also how they differ in their understanding of different concepts. The results will help us answer the following questions:

• Which time-use activities are misplaced or placed in newly created categories?

• What logic do participants follow in any new categories they’ve created?

• Which activities are consistently placed together in the correct category?

• Which activities are never put together, and are thus considered conceptually different by all participants?

• Do people suggest different labels for the categories?

6. Burden Hours and Costs for the Hybrid Card Sorting Task

The approach used for recruiting participants in the navigation tests will be used in both card-sorting tests. Therefore, the burden and cost estimates are the same as in the navigation tests.

III. Participants

125 participants will be recruited for each test through Amazon’s Mechanical Turk (MTurk) service. A general audience of adults (18 or older) will be recruited.

IV. Burden Hours

A total of 978 participants will be screened and 750 will complete a test. The screening survey is expected to take 2 minutes and follow-up tasks are expected to take an average of 20 minutes per respondent.

A summary of the various tests, maximum number of participants, and burden hours are listed below:

Test	Purpose	No. of Participants	Minutes	Burden Hours
Screening Tests	To determine eligibility for the tests below	978	2	32.6
Navigation Test 1	How well does an alphabetical ordering of Tier 1 activities work?	125	20	41.7
Navigation Test 2	How well does ordering Tier 1 activities by frequency of use work?	125	20	41.7
Navigation Test 3	Focused test of select ATUS tier 1 categories	125	20	41.7
