Beschreibung

Written in easy-to-understand language, this important text provides a systematic and commonsense approach to developing instruments for data collection and analysis. This book can be used by both those who are developing instruments for the first time and those who want to hone their skills, including students, agency personnel, program managers, and researchers.

This book provides a thorough presentation of instrument construction, from conception to development and pre-testing of items, formatting the instrument, administration, and, finally, data management and presentation of the findings. Throughout the book, the authors emphasize how to create an   instrument that will produce trustworthy and accurate data. To that end they have included guidelines for reviewing and revising the questionnaire to enhance validity and reliability. They also show how to work effectively with stakeholders such as instruments designers, decision-makers, agency personnel, clients, and raters or respondents.

PREFACE: ASKING AND ANSWERING

When word of the people’s discontent reached the grand vizier, he had trouble sleeping, for, you see, he was a conscientious ruler who had the welfare of his people at heart. He called upon the captain of guards and directed him to question members of the populace.

Dutifully, the captain of the guards rounded up one hundred people, men and women, and asked them a series of questions to discover the cause of their discontent. Now the captain was an imposing fellow, some six feet four inches tall and muscular. He wore a scimitar in a scabbard, and the medals he had won for his bravery in battle adorned his waistcoat. When he addressed the citizens, his voice had a hard and commanding tone, and he looked at them with the steely glare of a man ready for combat, which of course was how he approached all tasks.

“The grand vizier has commanded that you provide information about the quality of life in our kingdom. First, I want to know if you believe that taxes are too high?”

In unison all one hundred citizens responded, “No,” although records of this session suggest that some citizens responded less enthusiastically than others.

“Ah yes, good.” replied the captain of the guards. “Now tell me, do you think that the laws of the land are administered fairly?”

In unison all one hundred citizens responded, “Yes,” although it was noted that one citizen had recently lost property in a dispute with the vizier’s second cousin’s nephew.

“Splendid,” said the captain of the guards, and he exhaled a sigh of relief, for he did not relish bringing bad news to the grand vizier. “And do you citizens agree with the new law prohibiting mules in the marketplace?”

In unison all one hundred citizens responded, “Yes,” although several were merchants whose businesses were hurt by the new law.

And so the questioning went, and the captain of the guard was pleased that each time the citizens replied in unison and each time there was complete agreement to his question. Armed with this information (for the captain of the guards never went anywhere without being fully armed), he returned to the grand vizier. “Good news, my ruler,” he declared. “Although there is some grumbling among the populace, the people I spoke to, who were a diverse lot, all had good things to say about you and your administration. Sleep soundly now, for truly the kingdom is in good hands.”

The grand vizier did indeed sleep soundly, at least for a day or two, until word again reached him of the people’s discontent. Now this sorely vexed the vizier, for he had the best interests of his people at heart. But he was also confused, because what the people had told the captain of the guards was clearly at odds with what he continued to hear. For that reason he sent for Halcolm, a teacher and counselor, and asked him to go forth among the people to determine the source of their displeasure. Halcolm agreed to this task with the understanding that he would speak to the people in confidence, so that they could speak freely without fear of reprisal.

Now Halcolm was a man of simple and plain means, very undiscerning in appearance. His voice was calm and reassuring, and people tended to feel comfortable in his presence. While buying some fruit in the marketplace, he asked the vendor, “I’ve been thinking of opening a stand in the marketplace to sell candlesticks and other brass goods. Do you think I could make a profit at that?” The vendor smiled and replied, “Yes and no. Surely you should have a good market for your wares. But as to making a profit, it will be hard given the current tax rate. When the vizier decided to build an addition to the palace, he upped our taxes by 20 percent! I’ll be happy when that project is over, and the taxes are reduced.”

Further down the marketplace, Halcolm spoke with a rug vendor and asked the same question. “Yes,” the rug vendor replied, “you will certainly have a market for brass goods. However, the laws of the land are often applied unevenly, and they create a lot of headaches for us. For example, you might be fined if your cart is too close to the street. Also, since the vizier passed the rule outlawing mules in the marketplace, it is becoming increasingly difficult to carry our wares into town to sell. If changes aren’t soon made, many of us will go out of business. In the end, we, the vizier, and ultimately the entire kingdom will suffer under these rules. Now don’t get me wrong. I have great respect for the grand vizier. He has been a good and just ruler in the past. It is just that recently I think he has lost touch with the people.”

Halcolm continued his project and met with a number of people in the marketplace, at religious shrines, and at the theater. After several days of asking his questions he returned to the grand vizier and shared his findings. “Perhaps I have been out of touch,” sighed the vizier. “I will immediately revise my plans for constructing and financing the palace addition. Also, I will establish a committee to examine our laws and rewrite them so that they are fair and just. Thank you, Halcolm, for finding out what really troubled our citizens. I am pleased that the people were so honest in their responses. If I had depended on what people told the captain of the guards, my kingdom might have gone down in ruin,” and as he spoke those words, he glared at the captain of the guards, who was also present at this meeting.

“Thank you for your kind words,” responded Halcolm, “but I would like to add that as a teacher and counselor, it is my job to know how to ask the right questions and how to ask questions right. You would not, however, want me to lead your army into battle. For that, you would want your captain of the guards, who is an excellent tactician and great warrior.” With that, the grand vizier smiled, the captain of the guards smiled, and Halcolm smiled, for in addition to knowing how to ask a good question, Halcolm knew how to phrase a good answer.

(With special thanks to Michael Quinn Patton, for providing the evaluation profession a role model in the guise of Halcolm.)

 

Increasingly, individuals and organizations are being asked to collect, manage, and use information for decision making, particularly to improve the quality of services and products. Rather than being based on intuition or hunches, decision making is viewed as being a data-driven process, one that is systematic and produces trustworthy information.

The purpose of this book is to provide the reader with a systematic, nontechnical and commonsense approach to developing instruments for data collection and analysis. We have written the book as a guide for both those who are using or developing instruments for the first time and those with experience who want to hone their skills, people ranging from students to agency personnel to program managers to researchers. The book does not require any technical expertise and is written for all levels of readers.

Throughout the text we use the term instrument generically to describe any format for collecting data, such as attitudinal questionnaires, checklists, and political polls. And as we note in the text, the process for developing an instrument is the same whether that instrument will be used for self-rating (by a respondent) or whether another person (an observer) will fill it out.

There are literally thousands of instruments that have been developed and marketed to fulfill distinct needs for information. However, we have found that informational needs are often unique to a particular person, organization, situation, time, or event. Consequently, these needs can be met only by designing and developing a questionnaire for that specific purpose and situation. Additionally, finding a previously developed instrument may be time consuming, and the cost of purchasing the instrument may prove to be greater than the cost of developing a new instrument that uniquely fits your needs.

The approach presented here is based on the underlying assumption that the process of constructing an instrument is both a creative and a technical venture. It involves not only being very familiar with the content or substance of the topic of interest but also developing good questions or items and presenting them in a format accessible to the people who will have to complete the instrument. Consequently, this book is designed to help you create an instrument that will obtain the information you seek.

Throughout we emphasize the need to ensure that an instrument will produce trustworthy and accurate data. To that end, we provide guidelines for reviewing and revising to enhance data validity and reliability. Additionally, we stress the importance of involving, throughout the process of instrument construction, the different groups of people who will be affected by the data generated. These groups, referred to as stakeholders, include the instrument designer(s), decision makers (such as administrators, policymakers, and funding agencies), agency personnel, clients, and raters or respondents.

The ideas in this book are based on the authors’ experience in several hundred evaluation projects over the past twenty-five years. In addition, they have been presented in a variety of settings, from the university classroom to workshops on questionnaire construction. Moreover, in writing this text, we have addressed you, the reader, directly, as if we were present to advise you through this process. We hope this familiarity will make you more comfortable and less intimidated as you undertake the challenge of designing an instrument.

This book is organized around the process of instrument construction and takes the reader through each of the steps. The chapters in Part One present the conceptual basis for designing and constructing instruments for data collection and analysis. We describe how instruments fit into the process of social inquiry and how different types support specific informational needs. Before you decide on the type of instrument to construct, it is important to understand the variety of approaches available for gathering information about a particular research or evaluation question. These chapters describe the various types of instruments as well as the components of an effective instrument. We also introduce such concepts as validity and reliability.

The chapters in Part Two offer guidance in constructing questionnaires and other forms of instrumentation, helping you to define the purpose of your study, to understand and choose among the different ways to format items, and to pretest and construct items that will meet your informational needs.

Part Three provides guidelines for organizing the instrument, administering it, and reporting the results to stakeholders and decision makers. This is to ensure that the effort you put into obtaining reliable data, through a well-designed instrument, is not compromised when you actually carry out the measurement process.

To give you opportunities for applying the information presented in this text, the chapters conclude with examples of instruments. These instruments have been developed to meet different informational needs, and many come from the public domain. Each one is discussed and critiqued, and reviewing these samples can help you hone your skills both as a user of instruments and as a developer and designer of your own questionnaires.

Feedback

A central theme of this book is that instrument construction is a process of continual development and refinement. We welcome feedback and the sharing of information that can improve both the substance and presentation of our material. Please contact us through the publisher.

Acknowledgments

Our view that instrument construction involves constant revision has certainly held true during the development of this book. We want to express our appreciation to Daniel M. Stuhlsatz, of Mary Baldwin College, Staunton, Virginia, who reviewed an early version of the manuscript, and to Gary Skolits, of the University of Tennessee, Knoxville, Tennessee, who reviewed a revised version. Their feedback at both stages of development was incorporated into successive drafts.

We also want to acknowledge the students who have taken the instrument construction class we teach at the Curry School of Education, University of Virginia, as this book was in part written to address the topics and questions that typically arise there. Student projects have also provided useful resources, and one group in particular, the class of 2003, also reviewed and provided feedback for an early version of the manuscript. We offer special thanks to Tracey Armstrong, Ronda Bryant, Dan Bublitz, Holly Conti, Antoinette Ewell, Alan Fortescure, Jeanne Hineline, Sa Rah Ho, Amelia Hunt, Catherine Johnson, Jae Hyun Jun, Jennifer Mabry, Ana Paula Loucao Martins, Shizuka Modica, Yi Ni, Ana Palla, Margaret Peak. Nikkia Sheppard, Doug Toti, Dave Wolcott, Trimika Yates, Hyunsil Yoo, and Yubo Zhang. The multicultural makeup of this class led to very interesting discussions on translating instruments into different languages.

We also offer a special thank-you to our families for their support and encouragement during this drawn-out but fulfilling writing project. Finally, we thank the editorial staff at Jossey-Bass, in particular Elspeth MacHattie and Rachel Anderson, for their assistance in helping us through the publication process.

CHAPTER ONEINTRODUCTION

In this chapter we will

Explain the purpose and function of a social science instrument.

Describe nomenclature used to describe instruments.

List and describe the components of an instrument.

Outline the steps in the instrument construction process.

We are living in a time characterized as the information age, and we encounter data-gathering instruments in all facets of our lives. For example, we are familiar with polls that gather information about political preferences and voting behaviors. Surveys of potential voters try to predict who will be elected or what proposition will pass. Media commentators remind us of the margin of error associated with a survey or note that an election is still too close to call.

The proliferation of instruments to provide data and information for decision making is not unique to political polls. Survey questionnaires can be used to obtain factual information and to assess attitudes and beliefs across a variety of topics and groups. For example, surveys can assess consumer behaviors, client satisfaction with services, employee attitudes, and the general public’s values and beliefs. The federal government is perhaps the greatest consumer and user of survey questionnaires, as these instruments are used to collect data about such topics as criminal activity, educational needs, services to the mentally ill, and health care utilization, not to mention the data for the U.S. Census.

You may be familiar with other forms of measurement instruments as well. For example, many organizations conduct annual evaluations of employee work performance. Often these evaluation instruments use scales to rate job performance on a number of attributes, such as attendance, ability to work with others, or the ability to complete work tasks in a timely manner. Although the intended purpose of a checklist or rating instrument such as an employee evaluation is different from the purpose of a survey questionnaire, the same principles are used in constructing these instruments.
