QUALITY CONTROL DOCUMENTATION
RESPONSE RATES 
The response rate measures the extent to which interviews were completed from among the telephone numbers selected for the sample. The higher the response rate, the lower the potential will be for bias in the data.
No definitive formula for response rate estimates exists. The two estimates that are used for BRFSS provide a combination of monitoring information that is useful for program management. The formulas for each, translated into BRFSS call disposition codes, are-as follows:
CASRO: This response rate formula, developed by the Council of American Survey Research Organizations (CASRO), apportions dispositions with unknown eligibility status (ring-no-answer [04] and busy [10]) to dispositions representing eligible respondents in the same proportion as exists among all calls of known status (all other BRFSS call dispositions). The resulting estimate reflects telephone sampling efficiency as well as the degree of cooperation among eligibles contacted.

	(01+02+07+09)+ (03+05+06+08+11)		

Upper Bound; The most liberal of response rate formulas, the upper bound calculation includes only refusals (02s), terminations (09s), and completed interviews (01s). The resulting estimate reflects the cooperation of eligibles contacted and is not affected by differences in telephone sampling efficiency.

Because the rules of replacement are disregarded during wind-down interviewing (see page 3), total response rates for an interviewing period will not accurately reflect performance under the rules of replacement during regular mode interviewing. Therefore, the 1991 through 1994 response rate estimates included in this report have been calculated using only the records dispositioned during regular mode interviewing. Response rate estimates calculated for 1990 included wind-down records.
OTHER IMPORTANT QUALITY CONTROL INDICATORS
Survey Efficiency: The efficiency rate used for BRFSS is the percentage of All numbers called (excluding numbers rejected during Waksberg prescreening) that resulted in completed interviews. This indicator is directly related to the percent of telephone numbers in the survey area that are assigned to households. The degree to which interviewers adhere to survey procedures and gain respondent cooperation also affects efficiency. This percentage should remain static unless there is a change in the phone companies' assignment of phone numbers in the survey area, a change in sampling design, or a substantial change in interviewer performance.

Total Telephone Numbers Used	

Percent Ols on Day One: When using Waksberg cluster sampling, 33% of the telephone numbers have been identified as private residences through prescreening. Consequently, the objective for completed interviews on the first day of the interviewing period is 33% of the total sample. This percentage is important with Waksberg sampling because finishing within the BRFSS interviewing period is a function of how early in the interviwing period unproductive numbers are replaced. A broader objective, directly related to this one, is to strive to call, at least once, all available numbers on each interview occasion, including the first. If a different sample design than Waksberg is used, a different objective for the first day may be appropriate.
Wind-Down: In order to terminate data collection activities within the allotted time period each month, wind-down procedures (i.e., suspension of the rules of replacement) may be necessary with Waksberg sampling. Wind-down is permitted once 95% of the sample has been completed. Each interview completed in the wind-down mode should be coded as such. Generally, if the percentage of wind-down interviews is greater than five percent, the survey supervisor is going into wind-down too early. The greater the proportion of interviews completed in wind-down mode, the greater the potential is for bias in the survey results. This is because data collected during wind-down is reflective only of those respondents who are easiest to reach. Respondents who are more difficult to reach may differ significantly from those who are easier to reach.
Respondent Sex Distribution: The expected sex distribution within a population is approximately 52% female and 48% male. Survey samples with a respondent sex distribution that differs substantially from the norm may produce biased estimates of risk factor prevalences. Substantially skewed sex distributions suggest that interviewers may not be interviewing randomly selected respondents.
Refused Interview: The percentage of refusals (02s) of total numbers called in a given interviewing period is an indicator of both interviewer performance and degree of potential bias in the survey data. Ten percent1 refusals or less is a generally accepted standard.
Ring-No-Answer: The percentage of ring-no-answers (04s) reflects how many attempts are made and with what time variation on unanswered phone numbers. The objective for 04s is 10%1 or less of total numbers called. States that exceed this percentage may not be following prescribed call-back procedures or may be using this disposition inappropriately as a final disposition for a selected respondent who was not interviewed.
Selected Respondent Not Available During the Interviewing Period: This disposition (07) is used most often in wind-down and therefore reflects the proportion of calling done during wind-down. It also reflects the diligence of efforts to contact selected respondents whose availability is limited. The objective for 07s is 3%1 or less of total numbers called. Those states that exceed this percentage may need to use the entire 14-day interviewing period if they are not already.
Line Busy: This disposition (10) should be infrequent. The objective is 0.3%1 or less. A higher percentage than 0.3 may indicate that call-back procedures are not being carefully followed or that this disposition is being used inappropriately as a final disposition for a selected respondent who was not interviewed.
1Because this percentage is affected by the efficiency of the sampling methodology (i.e., by the number of 03 [nonworking] and 05 [nonresidential] dispositions in the denominator), comparisons between surveys with different sampling methods may not be meaningful. However, for a particular survey, month-to-month and year-to-year changes in this percentage are important to monitor.
