Probably the most common data collection method is the questionnaire (Alreck and Settle, 1995). Ranging from short reaction forms to detailed follow-up tools, questionnaires can be used both to obtain subjective information about participants and to document objective, measurable impact results for an ROI analysis. Because of this versatility, the questionnaire is the preferred method for capturing data at Levels 1, 2, 3, and 4 in some organizations.
A survey is a specific type of questionnaire with several applications in measuring program success. Surveys are used in situations in which only attitudes, beliefs, and opinions are captured; questionnaires are much more flexible, capturing a wide range of data from attitudes to specific improvement statistics. The principles of survey construction and design are similar to those of questionnaire design. This chapter explains how to develop both types of instruments.
Types of Questions
In addition to the types of data sought, the types of questions distinguish surveys from questionnaires. Surveys may elicit yes-or-no responses, if absolute agreement or disagreement is required, or they may solicit a range of responses, often on a five-point scale from âstrongly agreeâ to âstrongly disagree.â
A questionnaire may contain any or all of these types of questions:
- Open-ended questions allow unlimited answers. Questions are followed by ample blank space for the responses.
- Checklists provide a list of items, and the participant is asked to check those that apply in the situation.
- Two-way questions limit answers to a pair of alternative responses, such as yes and no.
- Multiple-choice questions provide several possible answers, and the participant is asked to select the one that is most applicable.
- Ranking scales require the participant to rank a list of items.
Questionnaire Design Steps
Nothing is more confusing, frustrating, and potentially embarrassing than a poorly designed or improperly worded questionnaire. Fortunately, with thought and planning, these problems can be easily avoided. Questionnaire design is a logical process that can be divided into simple steps. Use the following steps to help you develop a valid, reliable, and effective instrument (Robson, 2002).
Determine the Specific Information Needed
The first step in questionnaire design is reviewing the objectives, topics, skills, or attitudes presented in the program for potential questionnaire items. Developing this information in outline form is sometimes helpful so that related questions or items can be grouped. At this time, also explore issues related to the application and impact of the program for inclusion in the questionnaire.
Involve Stakeholders in the Process
To the extent possible, stakeholdersâclients, sponsors, supporters, or other interested partiesâshould be involved in the questionnaire design process. Ask those most familiar with the program to provide information on specific issues and concerns that might affect how the actual questions are framed for the questionnaire. In some cases, stakeholders may want to provide input on specific issues or items. Not only is stakeholder input useful in questionnaire design but it also builds ownership in the measurement and evaluation process and supports content validity.
Select the Types of Questions
From the five types of questions described previously, select the type or types that will result in the specific data needed. The planned data analysis and variety of data needed should be considered when deciding which types of questions to use.
Develop the Questions
The next step is to develop specific questions based on the type of questions selected and the information needed. Questions should be simple and straightforward, to avoid confusing the participants or leading them toward a desired response. Each question should address only one issue. If multiple issues need to be addressed, divide questions into multiple parts or develop separate questions for each issue. Avoid terms or expressions that might be unfamiliar to participants.
Check the Reading Level
To ensure that the questionnaire can be easily understood by the target audience, assess the reading level of the questionnaire. Many word processing programs have a function that can determine the reading difficulty of a text, indicating what grade level of education would be needed to read it. This important check ensures that the reading level of the questionnaire matches that of the target audience.
Test the Questions
Proposed questions should be tested to make sure that they will be correctly understood. Ideally, the questions should be tested on a sample group of participants. If this is not feasible, the sample group of employees should be at approximately the same job level as the participants. Seek feedback, critiques, and suggestions from the sample group so that the questionnaire design can be improved before it is administered to participants. Ensure that questions reflect program objectives and content.
Address the Anonymity Issue
Participants must feel free to respond openly to questions, without fear of reprisal. The confidentiality of their responses is of the utmost importance because there is usually a link between a questionnaireâs anonymity and respondentsâ honesty. Therefore, questionnaires and surveys should be anonymous unless individuals must be identified for specific reasons. In situations in which participants must complete the questionnaire as a captive audience or submit a completed questionnaire directly to an individual, have a neutral third party collect and process the data, to ensure that participantsâ identities are not revealed. In cases in which individual identities must be known (for example, to compare output data with previous data or to verify the data), make every effort to keep respondentsâ identities from being revealed to those who might be biased by their responses. Confidentiality goes a long way when collecting data for current or future evaluation projects.
Design for Ease of Tabulation and Analysis
Consider how each potential question will affect data tabulation, data summary, and data analysis. If possible, outline and review the data analysis process at this point. This step will help you avoid problems of inadequate, cumbersome, or lengthy data analysis caused by improper wording or design of questionnaire items.
Develop the Completed Questionnaire and Prepare a Data Summary
Integrate and develop the questions into an attractive questionnaire with instructions that will allow it to be administered effectively. In addition, develop an analysis spreadsheet so that the data can be tabulated quickly for analysis. Developing the questionnaire and planning data analysis in tandem will ensure appropriate and efficient reporting in the end.
Improving the Response Rate for Questionnaires and Surveys
The items on a questionnaire represent a wide range of potential issues to explore. Obviously, asking all of the possible questions could result in a reduced response rate. The challenge, therefore, is to design and administer the questionnaire so as to maximize the response rate while ensuring reliable responses. Asking too many questions can reduce the number of questionnaires returned; asking too few can negatively affect the reliability of the results. Response rate management is a critical issue if the questionnaire is the primary data collection method and most of the evaluation hinges on the response of the participants. Taking the actions discussed in this section can help increase response rates.
Provide Advance Communication
If it is appropriate and feasible, communicate with participants in advance about the requirement of completing the questionnaire. Advance warning reduces some of the resistance to the process, provides an opportunity to explain in more ...
