Todd Hughes is the director of the California Health Interview Survey (CHIS), the nation's largest ongoing state health survey. With over 25 years of experience managing population-representative household surveys, in roles that grew from face-to-face interviewer to survey director, he brings a comprehensive vision of what is needed for population surveys to be successful operationally, fiscally, scientifically, and methodologically. A passion for efficiency, a strategic view toward the future, and an eye for methodological creativity make him a valued leader in survey research.

In his role as director of the CHIS, Hughes oversees all data collection, survey research projects, vendor management, sample design, questionnaire development, data dissemination, and management of all project deliverables. He led the 2019 redesign of the CHIS survey methodology from a telephone survey to an address-based sampling design using mail push-to-web data collection with telephone follow-up, which required leading the development of field experiments, assessments of experimental results, and rolling out the new methods with CHIS data users and funders during the transition and implementation periods. He continues to develop new methodologies to ensure the CHIS operates effectively to represent California’s diverse population, and also works to leverage the CHIS data infrastructure to support follow-on studies of special topics and subpopulation groups in collaboration with researchers across the U.S.

Prior to his tenure at UCLA, he was the assistant division chief of the U.S. Census Bureau's American Community Survey (ACS), where he helped oversee the 3.5-million households survey with an annual program budget of up to $250 million. During his tenure, he oversaw new efforts to increase response rates, including an internet response option as well as changes in ACS mail methodology, and adaptive design principles on follow-up methods. During his career at the U.S. Census, Hughes also supervised data collection for the Current Population Survey, Consumer Expenditure Survey and other Census surveys.

Hughes holds a master's certificate in project management from The George Washington University School of Business and Public Management and a bachelor of science in statistics from Brigham Young University.

Improving the Efficiency of Outbound CATI As a Nonresponse Follow-Up Mode in Address-Based Samples: A Quasi-Experimental Evaluation of a Dynamic Adaptive Design

This article evaluates the use of dynamic adaptive design methods to target outbound computer-assisted telephone interviewing (CATI) in the California Health Interview Survey (CHIS). CHIS 2022 implemented a dynamic adaptive design in which predictive models were used to end dialing early for some cases. 

For addresses that received outbound CATI follow-up, dialing was paused after three calls. A response propensity (RP) model was applied to predict the probability that the address would respond to continued dialing, based on the outcomes of the first three calls. Low-RP addresses were permanently retired with no additional dialing, while the rest continued through six or more attempts. Authors used a difference-in-difference design to evaluate the effect of the adaptive design on calling effort, completion rates, and the demographic composition of respondents. 

Findings: Authors find that the adaptive design reduced the mean number of calls per sampled unit by about 14% (relative to a modeled no-adaptive-design counterfactual) with a minimal reduction in the completion rate and no strong evidence of changes in the prevalence of target demographics. This suggests that RP modeling can meaningfully distinguish between addressed-based sample units for which additional dialing is and is not productive, helping to control outbound dialing costs without compromising sample representativeness.

The Post-Pandemic Agenda for Community Well-being among Asian Americans, Native Hawaiians, and Pacific Islanders in California

Summary: The COVID-19 pandemic has adversely affected Asian Americans, Native Hawaiians, and Pacific Islanders (AA and NHPIs) in many ways — through economic hardship, negative health outcomes, and rising incidents of hate and violence. The pandemic also exposed fissures and challenges facing Asian Americans and NHPIs that were already deep-rooted in California. This report, which builds upon an earlier report​ released in June 2022, aims to identify any changes in accessing services before and after the onset of COVID in 2019 and 2021, respectively, and to take a closer look at the challenges that AA and NHPI communities face in the post-COVID period, including anxieties associated with gun violence and experiences with hate and discrimination.

Authors examine data from the 2019 and 2021 1-year American Community Survey Public Use Microdata Sample (PUMS) and the 2018-2021 California Health Interview Survey (CHIS), including a 15-minute follow-on survey for 2021 CHIS AAPI respondents to identify trends in social service utilization and gaps in accessing health, mental health, and social services for AA and NHPI communities in California. 

Findings, by major section: 

HEALTH

  • Between 2019 and 2021, Hispanics/Latinos and Asian Americans had statistically significant increases in reports of delays in health care due to system and provider barriers.
  • By 2021, Asian Americans and NHPIs were more likely than Whites to rely on community-based health care. 
  • About 3 in 10 Asian Americans in California reported difficulties in accessing health services, and cited financial cost, lack of awareness about options, lack of insurance, and limited English proficiency as the most salient challenges.
  • Doctors, government health agencies, and friends/family remain by far the most trusted sources of medical information for Asian Americans. Only 37 percent of Asian Americans trusted social media apps for medical information.​

MENTAL HEALTH AND COMMUNITY WELL-BEING: 

  • Suicide ideation increased between 2018/19 and 2020/21 for Asian Americans, as for many other groups, with increases especially pronounced among non-U.S. citizens.
  • Yet the share of Asian Americans receiving mental health services did not change before and after the onset of COVID. 
  • Major barriers for finding mental health services include lack of knowledge about available options, financial cost, lack of insurance, and limited options in their neighborhood. 
  • Fear of gun violence is a significant contributor to community anxiety and the lack of well-being.
  • Even before the 2023 shootings in Monterey Park and Half Moon Bay, California, Asian Americans and NHPIs were the groups most worried about becoming a victim of gun violence.

EXPERIENCES WITH HATE 

  • One in 4 Asian Americans in California reported having ever experienced a hate crime or hate incident, with Southeast Asians reporting the highest levels of experiences with hate. 
  • Among those who had ever experienced hate crimes or hate incidents, most had done so before 2020.
  • Asian American men were significantly more likely than Asian American women to be threatened or harassed (16% vs.10%, respectively) and also more likely to have been mocked or had offensive physical gestures made towards them (15% vs. 9 %, respectively).
  • About 1 in 5 Asian Americans in California worried "all the time" or "often" about being a victim of a hate crime, with worries especially high among Filipino Americans.

SOCIAL DETERMINANTS: ECONOMIC STATUS, HOUSING, EDUCATION, FOOD SECURITY

  • Asian Americans, Native Hawaiians, and Pacific Islanders all saw higher poverty rates, and lower labor force participation rates, in 2021 than in 2019.
  • The labor force participation rate for Indian Americans increased slightly between 2019 and 2021, while Chinese, Filipino, and Vietnamese Americans saw statistically significant decreases.
  • The share of NHPI homeowners with mortgages who were burdened with housing cost (spending 30% or more of household income on housing) increased from 35% to 45% between 2019 to 2021.
  • Asian Americans in California report relying mostly on friends or family members for assistance in accessing quality or affordable housing, with government agencies a distant second.
  • About 2 in 5 Asian American respondents indicated that they had difficulty finding quality or affordable education, with financial cost as the most common reason across groups.

Impacts of Transition Statements in Survey Questions on Survey Break-off: Evidence from a Survey Experiment

Summary: The California Health Interview Survey (CHIS) has employed an addressed-based sampling (ABS) frame with a mail push-to-web interview followed by a telephone nonresponse follow-up as the primary data collection approach since 2019. However, the nature of the self-administered web survey results in more survey breakoffs than the previous computer-assisted telephone interview (CATI). During CHIS 2021 data collection, the CHIS team observed that a large proportion of questions with high break-off incidence began with transition statements, such as “The following questions are about…” or “These next questions are about...”. Therefore, experiments were warranted to test whether eliminating transition statements leads to a reduction in survey breakoffs during CHIS 2022.

This study evaluates an experiment conducted in CHIS 2022, where respondents were evenly split and randomly assigned to two conditions: (1) a treatment group where transition statements were removed from the selected twenty-six questions; (2) a control group with the original question wording, including transition statements.

Findings: Data demonstrate that eliminating transition statements results in substantive survey break-offs reductions. Aggregated breakoffs from the 26 questions have decreased by 44.2%. For individual questions, reduction rates range from 14% to 82%. Results also show that removing the transition statements converted sufficient partials to fully completes and slightly shortened interview length. Consequently, all transition statements except an outlier have been removed for the remainder of the CHIS 2022 and transition statements will be less likely to be included in new survey question development for the CHIS.

The Health, Mental Health, and Social Service Needs of Asian Americans and Pacific Islanders in California

Summary: Health data for Asian Americans (AA) and Native Hawaiians and Pacific Islanders (NHPI) are often grouped into an "overall" category. However, when the data for each ethnicity within AA and NHPI populations are looked at individually, or disaggregated, wide variations in health are obvious. 

The onset of COVID-19 has amplified the importance of disaggregating AA and NHPI health data. The coronavirus has taken a specific toll on the physical and mental health of these communities, with increased verbal and physical attacks on Asians taking a mental and physical toll, and the demand for on-site essential workers – many of whom are NHPI – exposing them to higher rates of illness and death. Being aware of variations in need within the AA and NHPI populations is critical to understanding how to improve their health. 

This report published jointly by the UCLA Center for Health Policy Research and the University of California, Riverside, uses pooled 2019–2020 California Health Interview Survey (CHIS) to identify trends in social service utilization and gaps in accessing social and mental health services for specific AA and NHPI communities in California and compares them with data for six other major racial and ethnic groups. Categories studied include housing and poverty, public program utilization, access to and use of health care, mental health, health behaviors, reproductive health and nonconsensual sex, food insecurity, child care and preschool, and caregiving.

This report includes the U.S. Census Bureau’s American Community Survey, when relevant measures are available in the data set, as well as other data from public opinion sources such as American Experiences with Discrimination Survey from AAPI Data and Momentive.

California Health Interview Survey finds more than half of California adults have ever received a positive test result for COVID-19

California Health Interview Survey finds more than half of California adults have ever received a positive test result for COVID-19 

New data from the California Health Interview Survey highlights reasons for not getting vaccinated, personal and financial impacts of the pandemic, and more

Media Contact:
UCLA CHPR Communications Team

More than half — or 55% — of California adults said they have received a positive COVID-19 test result: 46% used only a self-test kit, 27% received their positive result from both a self-test kit and testing site, and 26% from a clinic, hospital, lab or other test, according to May 2023 data released today by the California Health Interview Survey (CHIS). 

While self-test kits have made it faster and more convenient to test for COVID-19, the results are not reported to health care providers or local public health departments, making case rates impossible to track.

The data, made available to the public on the 2023 California Health Interview Survey Preliminary COVID-19 Estimates Dashboard, was published today by the UCLA Center for Health Policy Research using surveys collected in May 2023 from 3,660 California adults and 717 teenagers and children. The dashboard features information about access to masks, vaccination status and reasons for not getting vaccinated, COVID-19 testing and more.

Data shows that Californians continue to experience personal and financial impacts. About 11% of California adults experienced financial difficulties with paying rent or mortgage, 2% reported being treated unfairly because of their race or ethnicity, 3% quit their job to care for themselves or a family member due to COVID-19 illness, 2% experienced financial difficulties with paying COVID-19 medical bills, and 2% had difficulty obtaining child care, or experienced an increase in child care experiences.

“Although you may think some of the percentages are small at 2% — when considering the overall California population, we’re talking about more than half a million Californians,” said Todd Hughes, director of the CHIS. “There is nothing insignificant about that. Thousands of Californians are still impacted, years after the initial COVID-19 outbreak.”

The data also highlights some disparities among racial and ethnic groups: 17% of Latinx adults said they had financial difficulties with paying rent or mortgage, three times the 5% of white adults who experienced difficulties.

Other highlights include:

Vaccination Status

  • More than 1 in 3 (37%) California teens and children have not completed the primary vaccine series for COVID-19.
     
  • More than half (56%) of teens said the reason they have not completed the primary vaccine series is because their parents don’t want them to get the vaccine.
     
  • Among California adults who have not completed the primary vaccine series for COVID-19, 48% think a vaccine for COVID-19 is unnecessary.
     
  • More than a third (36%) of California adults said they will not get additional COVID-19 vaccine doses if recommended by health guidelines.

Mask Use

  • 1 in 8 (12%) California adults said they would not wear a N95, KN95, or KF94 mask even if public health recommended it as a COVID-19 protection.
     
  • 1 in 9 (11%) California adults said they could not get an N95, KN95, or KF94 mask even if public health recommended it as a COVID-19 protection.
     
  • Among California adults who do not have a N95, KN95, or KF94, 43% of California adults said the reason for not being able to get an N95, KN95, or KF94 mask is because they are too expensive.
     

Earlier this month, CHIS released March and April 2023 COVID-19 data and will be releasing additional data in the coming weeks.

Three Questions with Todd Hughes on California Health Interview Survey (CHIS)

 

Ask the Expert Todd

Todd Hughes is the director of the California Health Interview Survey (CHIS), the nation’s largest state health survey. In this brief interview, Hughes discusses the survey’s new topics and his vision for new data collection methods. 

Q: What new topics and questions are covered in the 2018 CHIS? 

The questions included in CHIS vary somewhat each year to reflect emerging health issues and the evolving needs of our funding organizations. The 2018 questionnaire included new questions about tobacco and e-cigarette usage, including questions about flavored tobacco and e-cigarette products; usage of non-cigarette tobacco products; secondhand smoke exposure; and rules on smoking and vaping. Additional questions on quality of life were added to allow for the creation of a well-being measure. 

Also, to better understand the health impacts of the implementation of California’s Adult Use of Marijuana Act, additional detailed questions on marijuana use, methods of use, and whether use was for medical purposes, were added in 2018. 

Finally, questions on condition of teeth and missing school due to dental problems returned to the CHIS teen survey in 2018. 
 

Q: What data may be of interest to policymakers and news media? 

Last year CHIS identified evidence of declines in mental health in 2017, and in 2018, CHIS provided further evidence of declines in mental health and increases in the use of mental health visits. In fact, 2018 CHIS respondents reported the highest levels of both moderate and severe impairment due to mental and emotional health challenges ever seen in CHIS. 

Current e-cigarette usage was found to be quite high in 2018 among young adults age 18-25 years old, and the data indicate that among this age group, many young adults are trying e-cigarettes and continuing with current use. Marijuana usage in the past 30 days has significantly increased in 2018; and although smoking marijuana in a joint is the most popular method of use, vaping cannabis is also frequently reported. With the recent focus on pulmonary disease related to vaping reported by the U.S. Centers for Disease Control and Prevention, it will be important to continue to monitor rates of vaping cannabis or nicotine in California using CHIS. 

Finally, 2018 CHIS data for insurance coverage show that California uninsured rates in 2018 remain lower than prior to the implementation of the Affordable Care Act.  California’s interventions to reduce the effect of federal policy changes are allowing the uninsured rate here to remain stable, despite increases in the national uninsured rate. 

  

Q: It was recently announced that CHIS will transition to a mixed-mode survey allowing respondents to answer via web or telephone. What is your vision on how this will transform data collection and response methods for such a well-cited survey? 

CHIS is innovating in order to respond to increasing challenges with obtaining high levels of participation in today’s environment. With cultural changes in telephone usage and technological developments such as caller ID, robocalls, and call blockers, it was becoming more and more expensive to rely on the telephone as the only method of data collection for CHIS, as has been done since the inception of CHIS in 2001. 

In 2018, we designed and conducted two independent field tests exploring a new design for CHIS: Mailing invitations to a representative sample of addresses across the state to encourage these selected households to go online to complete CHIS, and then following up by telephone (when a phone number can be identified for the address) with those households that don’t respond by web. Due to the success of these tests, the 2018 CHIS will be the last round of CHIS conducted by telephone only. The 2019 CHIS will move to the new design using web plus phone. 

Using a mail invitation for households to respond by web will allow us to more successfully reach busy households that aren’t likely to respond by telephone. Retaining the option for telephone interviewing will allow us to include households that don’t have internet access, or may be more comfortable participating by phone, such as the elderly population. Both the web and telephone versions of the survey will include multiple languages other than English to ensure that CHIS continues to represent the linguistic diversity of California.

California Health Interview Survey data show majority of California adults less likely to wear masks

California Health Interview Survey data show majority of California adults less likely to wear masks

The number of California adults who said they “always” wore a mask during the pandemic dropped significantly between February and July, according to the latest CHIS COVID-19 Preliminary Estimates

Media Contact:
UCLA CHPR Communications Team


Although the COVID-19 pandemic continues to affect the nation, only 30% of California adults said in July that they “always” wore a mask when they left their homes, according to a new UCLA survey. This is a significant decrease from the 54% who “always” wore a face covering in February and March.

And most California adults (51%) said they “sometimes” or “never” use a mask, compared to 48% who said they “always” or “usually” do.

These are among the latest findings on the 2022 California Health Interview Survey (CHIS) Preliminary COVID-19 Dashboard, published by the UCLA Center for Health Policy Research.

“Our focus is to constantly shed light on the impacts the pandemic has had on people across the state,” said Todd Hughes, CHIS director. “Our most recent findings show that risk reduction behaviors dramatically decreased among the state’s population, despite a very active period of the pandemic this summer.”

The dashboard uses responses collected in July from 2,992 adults and builds on previous months of data. Beyond risk reduction behaviors among California adults, the dashboard also includes insights about many topics, such as the pandemic’s personal and financial impacts, which outlets Californians use to gather their COVID-19 news and information, and perspectives on receiving a COVID-19 booster shot. 

The survey also highlights how Californians’ sources of news and information about COVID-19 play a role in their response to the pandemic. Thirty-five percent of California adults got their news and information from television, while 19% got news and information from social media. 

Other highlights: 

COVID-19 Booster Shots  

• 52% of adults in California said they have already received a booster. • 31% of adults in California said they are “very likely” to receive a booster. 

Risk Reduction Behaviors

• 21% of adults in California never wore a face covering when leaving their home in the past week.

• 38% of California adults 65 and older always wore a face covering when they left home in the past week, while 27% of California adults ages 18-64 always wore a face covering when leaving home.

• 30% of California adults with a health risk factor (including asthma, diabetes, or high blood pressure) always wore a face covering when they left home in the past week, while 17% of California adults with a health risk factor never wore a face covering when they left home in the past week.
 
Personal Impacts of the Pandemic

• 18% of California adults continued to work entirely in person because it is required by the employer, and the same percentage worked entirely from home.
