Funding Opportunities

Due By: 6 p.m. PST on March 31, 2020

PHFE, a California nonprofit corporation, is seeking to contract with a survey research firm to conduct the 2020 Los Angeles County WIC Survey. The contractor will conduct a telephone survey of 6,000 recipients of the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) in Los Angeles County.
The following is a summary of the specifications and survey procedures to be followed by the selected contractor:

  • Survey 6,000 WIC recipients in Los Angeles County. The survey will be conducted by telephone in English and Spanish by professionally trained and monitored telephone interviewers working from a central location call center.
  • The survey will include a countywide random sample of 4,750 WIC recipients and augmented samples of WIC recipients within selected sub-regions of the county. The augmented samples will include approximately 250 interviews among a random sample of WIC recipients in the county’s Antelope Valley Service Planning Area, and approximately 1,000 additional interviews among random samples of WIC recipients in First5 LA’s fourteen Best Start communities. The exact allocation of interviews across the fourteen Best Start communities will be determined in consultation with the contractor, with the goal of obtaining minimum sample sizes within each community based on interviews from the countywide cross section sample and from the augmented samples.
  • Eligible respondents will include the mothers or primary caregivers of children age 0-5 who receive WIC benefits or mothers who are currently pregnant and only qualify for WIC benefits as a result of their pregnancy.
  • Random samples of eligible respondents will be drawn by PHFE WIC program staff from its internal list of WIC recipients within each jurisdiction, and will be provided to the contractor at no cost. The file will include the recipient’s telephone number, the recipient’s first name, and his/her preferred language, along with the appropriate target population from which it was drawn.
  • PHFE WIC staff will mail out a pre-approach letter to each WIC recipient selected for the survey prior to telephone survey administration. This will not only serve to alert the respondent that an interviewer calling on WIC’s behalf will be contacting them in the near future, it will also help to identify and update listings that may be incorrect or out-of-date, thereby reducing the number of unusable listings called. These mailings and re-mailings will be closely coordinated with the contractor to maximize survey response.
  • PHFE WIC staff will also be responsible for mailing out a thank you note, including a $10 gift card gratuity, to each survey participant shortly after completion of their interview. The timing of the post-survey mailings will be coordinated with the contractor, so that they are mailed out within two weeks of survey administration.
  • PHFE WIC staff will have primary responsibility for the development of the survey instruments. Two slightly different questionnaires will be developed. The main questionnaire will be administered to parents or primary caregivers with one or more children under age 5 who currently receive WIC services. A second, somewhat shorter, questionnaire will be administered to women who are currently pregnant and only qualify for WIC benefits as a result of their pregnancy. The contractor may assume that over 95% of all interviews will be completed with respondents using the main questionnaire. (Copies of the main questionnaire from prior LA County WIC Surveys are available at
  • The average interview length of the main questionnaire will not exceed 25 minutes in English (or 30 minutes in Spanish), and all questions will be closed-ended. The contractor may assume that about half of the interviews will be conducted in English and about half in Spanish. The survey instruments will be based largely on those developed for the last LA County WIC Survey in 2017, but up to 25% of the questions may be new or revised versions of previous questions. The contractor will be expected to offer professional advice and assistance to PHFE WIC staff throughout the questionnaire development process.
  • Once the survey instruments have been finalized, PHFE WIC staff will be responsible for translating them into Spanish, and for securing all necessary IRB approvals applicable to the study.
  • The contractor must specify whether they will use CATI programming to administer the survey and, if not, what survey technology they would be using.
  • Prior to the start of full-scale data collection, the contractor will conduct a pre-test of the survey instruments with eligible respondents in English and Spanish.
  • Since many of the telephone listings provided to the contractor will be cell phones, and these will not be identifiable in advance, all telephone numbers must be hand dialed and may not be placed using auto-dialers.
  • Access to the sample list files containing subjects’ telephone numbers will be limited only to essential staff who require such access. The contractor must take measures to insure that all data collection, including pre-testing, be conducted so that the telephone numbers being dialed are blind to the interviewers placing the call. In the past this has been done by having the call management system scramble the telephone numbers shown to the interviewer. After the scrambled number is dialed, the call management system unscrambles the number before placing the call.
  • Up to sixteen attempts should be made to attempt to reach and interview each eligible subject. Calls should be attempted throughout the day and early evening hours on weekdays and on weekends.
  • Results of a 2019 survey conducted with WIC families from across California demonstrated a reduction in response rates compared to the 2017 Los Angeles County WIC Survey, particularly among English-speaking participants. The contractor is invited to propose additional strategies (i.e. hybrid methods for collecting data such as online + phone surveys) for reaching families who may not readily answer a phone survey. However, it is essential that the methodology applied to the 2020 survey allow for comparisons to be drawn to data collected in the previous administrations of the LA County WIC Survey (conducted triennially since 2005).
  • After the completion of interviewing, the contractor will be responsible for checking the data file to make sure the data are internally consistent and free of error. The contractor will also provide recommendations and assistance in developing post-stratification statistical weights, as appropriate, and include them in the data file.
  • Upon completion of data processing, the contractor will provide PHFE WIC staff with a SAS data file, along with a detailed data codebook. The contractor will also prepare a written description of the survey methods used to implement the survey, including a disposition of all interview attempts, at the conclusion of the project. The contractor will not be responsible for preparing any survey tabulations or written analyses of the data.
