SECTION ONE
Basics of Survey Research
SECTION 1BASICS OF SURVEY RESEARCH
Objectives
Describe what surveys are used to measure Give examples of how surveys can assess change Define "needs", "assets", "behavior", "opinions",
"attitudes", "beliefs"
Key Terms:questionnaire, descriptive research, prediction, evaluation, samples, panel study
4
WHAT DO SURVEYS MEASURE?
Behavior, attitudes and beliefs
5
DO A SURVEY (QUESTIONNAIRES)
Surveys are a systematic way of asking people to volunteer information about their attitudes, behaviors, opinions and beliefs. The success of survey research rests on how closely the answers that people give to survey questions matches reality that is, how people really think and act.
The problem that a survey researcher has to tackle is how to design the survey so that it gets the right information.
Is this survey necessary? Is the purpose of the survey to evaluate people or programs? Can the data be obtained by other means? What level of detail is required?
6
WHY DO A SURVEY? The survey is an appropriate means of gathering
information under three conditions:
when the goals of the research call for quantitative and qualitative data,
when the information sought is specific and familiar to the respondents and;
the researcher has prior knowledge of the responses likely to emerge.

USE OF SURVEYS BY STUDY DESIGN
Descriptive research
Causal explanation
Evaluation
Prediction

BASIC SURVEY DESIGNS
Cross-sectional surveys: Data collected at one point in time selected to
represent a larger population
Longitudinal Surveys: Trend:
Surveys of sample population at different time points Cohort:
Study of sample population each time data are collected but samples studied maybe different
Panel: Data collection at various time points with the same
sample of respondents

SECTION TWO
Types of Data
TYPES OF DATA COLLECTED
There are six basic types of data that you might collect:
Attitudes Opinions Beliefs Behavior Attributes (demographic characteristics) Preferences
11
BASIC TYPES OF SURVEY QUESTIONS
The way a question or statement is worded and the response options offered determine the nature of the data received.
Types of survey questions include:
Open-ended response Agreement and rating scales Closed response Semantic differential scales Ranking scales Checklists
12
BASIC TYPES OF SURVEY QUESTIONS
Open-ended question: Respondent writes response in own words.
Agreement scales End points are identified by adjectives or phrases Example:
a five point scale with steps labeled Strongly Agree, Agree, Neutral, Disagree, and Strongly Disagree.
13
BASIC TYPES OF SURVEY QUESTIONS
Closed response: These are the "multiple-choice" variety where a
person has to choose among several possible answers.
Example:
Which of the following do you believe increases your risk for stroke?
Yes No Don’t know Smoking Overweight Stress Drinking alcohol

SECTION THREE
Elements of Item Construction
SECTION THREEELEMENTS OF ITEM CONSTRUCTION
OBJECTIVES
Identify types of bias in questionnaires Identify and state how to correct common
wording problems Define types of response sets
Key Terms Social desirability, acquiescence, bias,
midpoint, operational definition
20
HOW BIAS AFFECTS RESPONSE?
Need to say more?21
WRITING QUESTIONS
Good Questions Are clear and use simple language Are concise Are specific Are possible to answer Are relevant to the respondent Do not use negatives Avoid bias terms Have only one part (not two parted question)
22
RESPONSE OPTIONS
Should reflect concepts you are trying to measure, and fit with the wording of the question Avoid simple “yes” or “no” answers and attempt
to measure intensity if possible
Mutually exclusive (select only one answer)
Exhaustive (all possible answers are listed, including other or not applicable or don’t know)
23
QUESTION ORDER
Start with easy, salient, non-threatening questions near the end
Cluster questions addressing the same topic or concept together.
Avoid redundancy
24
QUESTIONNAIRE FORMAT
As short as possible Visually attractive and nicely reproduced Readable (consider font size) Uncluttered Broken into logical sections if possible Clear skip patterns for contingency questions Clear spaces for respondents to mark answers
Boxes Parentheses (X) Or numbers to circle 1…2…3 Avoid lines to put check___
Amount of space provided for open-ended questions will determine amount respondent will write.
25
INSTRUCTIONS TO RESPONDENTS
General instructions should be provided at the beginning of the self-administered survey Brief explanation includes:
Purpose Significance of the answers How to answer the questions Stress: CONFIDENTIALITY OF RESPONSES
Provide specific instructions to questions as needed
26
PRE-TEST (PILOT)
Be sure to pilot test the survey instrument before the actual administration, especially if it is a new instrument that you constructed or has not been used previously in your population of interest.
Helpful Hint: Also good idea to test your sample design, data
collection analysis if possible.
