Frequently Asked Questions about the Community-wide Children’s Health Assessment & Planning Survey (CCHAPS)

Data FAQ


What is CCHAPS?
CCHAPS is the acronym for Community-wide Children's Health Assessment and Planning Survey. Cook Children's conducted an assessment to collect comprehensive data about children's health in our six-county service region (Tarrant,Johnson, Hood, Parker, Wise and Denton Counties).


Why conduct a children's health assessment?
Coordinated community-wide health resources and health information for every child in our region are required for Cook Children's to fulfill our promise to improve the health of every child in our region through the prevention and treatment of illness, disease and injury. This requires that reliable, local health data about our community's children are consistently available. This information will allow our community to:

What survey methodology was used for CCHAPS?
To reduce the length of the survey, two versions of the survey were developed which minimized the burden on respondents to finish the survey in a reasonable amount of time and helped to ensure a good response rate. A core set of questions was included on both versions of the survey and questions related to specific children's health issues were then divided between the two surveys. Each version of the survey was seven pages long and it took an average of about 25 minutes to complete.

In 2009, a total of 21,530 households and in 2012, a total of 23,000 households with children 0-14 years of age were selected at random to receive a survey. Only one parent per household was selected. Half of the sample received Version One of the survey and the other half of the sample received Version Two. The sample was stratified to ensure that the results for each county, the City of Fort Worth, the City of Arlington, and the City of Denton were statistically valid. In 2009, this involved the completion of nearly 3,500 surveys in Tarrant County, nearly 1,500 surveys in Denton County, and more than 400 surveys in Hood, Wise, Johnson, and Parker Counties. In 2012, based on the counties total population, this involved the completion of more than 5,000 surveys in Tarrant County, more than 2,000 surveys in Denton County, approximately 400 surveys each in Johnson and Parker Counties and more than 150 in Hood and Wise Counties.

The parent survey was administered by a combination of mail, phone, and the Internet. The survey included a cover letter that explained the purpose of the survey and respondents were initially given the option of returning the survey by mail or completing the survey on the Internet. Households that did not respond to the first request were then contacted and given the opportunity to participate by phone. The goal for both surveys was to obtain a response rate of at least 33%.

In 2009, a total of 7,439 parents completed the 2009 survey (response rate 37%); 3,492 completed the survey by mail; 3,612 completed the survey by phone; and 335 completed the survey on the Internet. Surveys were administered in both English and Spanish (a total of 892 surveys were administered in Spanish).

In 2012, a total of 8,439 parents completed the 2012 survey (response rate of nearly 37%); 4,490 completed the survey by mail, 3,619 completed the survey by phone, and 285 completed the survey on the Internet. Surveys were administered in both English and Spanish. A total of 926 surveys were administered in Spanish

The sampling plan for the 2015 survey was designed to gather statistically representative data from parents of children ages 0-14 living in Denton, Hood, Johnson, Parker, Tarrant and Wise counties. A total of 25,000 parents in the region were selected at random to receive the survey. Only one parent per household was selected. Half of the sample (12,500 parents) received Version 1 of the survey. The other half of the sample (12,500 parents) received Version 2.

The actual number of completed surveys was 8,661 which represented a response rate of nearly 35%, which was comparable to the response rates from the 2009 and 2012 surveys. The sample was stratified to ensure that the results for each county were statistically valid and that all communities in the six-county region were represented. The survey was administered by a combination of mail, phone, and the internet. The survey was initially mailed to each of the 25,000 households that were selected for the sample. The survey included a cover letter that explained the purpose of the survey. Respondents were initially given the option of returning the survey by mail or completing the survey using the internet. Households that did not initially respond to the survey were then contacted by phone and given the opportunity to participate by phone. Of the 8,661 parents that completed the survey, 4,172 completed the survey by mail, 4,109 completed the survey by phone, and 380 completed the survey using the internet.


What's the precision or accuracy of the survey results?
2009 - The overall results for questions that were included on both versions of the survey for the random sample of parents have a precision of at least +/- 1.1% at the 95% level of confidence. The results for questions that were included on just one version of the survey have a precision of at least +/- 1.6% at the 95% level of confidence.

2012 - The overall results for questions that were included on both versions of the survey for the random sample have a precision of at least +/-1.1% at the 95% level of confidence. The results for questions that were included on just one version of the survey have a precision of at least +/-1.5% at the 95% level of confidence.

2015 - The sampling plan for the 2015 survey was designed to gather statistically representative data from parents of children ages 0-14 living in Denton, Hood, Johnson, Parker, Tarrant and Wise counties. A total of 25,000 parents in the region were selected at random to receive the survey. Only one parent per household was selected. Half of the sample (12,500 parents) received Version 1 of the survey. The other half of the sample (12,500 parents) received Version 2.


Why is the number of respondents different for some questions?
The “n” provided with each question is the actual number of respondents to that question. The survey was split into two versions, with a core set of questions included on both versions of the survey for all respondents and questions related to specific children's health issues were then divided between the two survey versions. Half of the parents received version one of the survey and the other half received version two.


Why is there a relatively large number of “Don't Know” responses for some questions?
Some survey respondents were foster parents, kinship care providers (grandparent, aunt/uncle, sibling, etc.), noncustodial parents and other caregivers. These groups may not be as familiar with the child's health issues or access to health services as custodial parents.


Who administered the survey?
CCHAPS was administered by ETC Institute on behalf of Cook Children's Health Care System.
