Document Summary
Survey types: questionnaires, interviews, self-report diaries. Research has shown that this is the most important stage in survey design. Inexperienced item writers generate items that are as good as experienced item writers if they are aware of the principles of good item-writing, and have a good definition of the constructs. Critical incident technique: often require follow-up questions for clarification, tend to be subjective, analyzed with content analysis, close-ended items, specific set of alternative answers, partially open-ended items, forced choice items, rating scales. Scales: categorical scales, participants assigns self to a category, categories must be mutually exclusive, continuous scale, ranked scales. Scale scores: summative scales, each item contributes equally to the total score, cumulative scales, each item represents an increasing amount of the attribute being measured, scaling models, likert scales. Summative scaling method involving ranked values: semantic differential, another summative scaling method, measures individual"s feelings about a particular construct by scaling between two extremes, visual analogue scales.
