Handbook of Marketing Scales by
The Handbook of Marketing Scales, Third Edition represents a clear, concise, and easy-to-use compilation of multi-item, self-report measures developed and/or frequently used in consumer behavior and marketing research. - Over 150 scales are included in the handbook. Many of these scales were originally published in marketing- and consumer-related journals or conference proceedings. Including them in one volume helps reduce the time it takes to locate instruments for survey research. - Scales included have a reasonable theoretical base, are developed within the marketing or consumer behavior literature, are composed of several items or questions, use some scaling procedures, and include estimates of reliability and/or validity, making these scales especially relevant and "proven" for marketing scholars and professionals. - Each scale includes the following information so that users can quickly and easily learn about the scale: construct, description, development, samples, validity, scores, sources, other evidence, other sources, references, and scale items.
