Effects of Different Data Collection Strategies on Q-Technique Factor Analytic Results.
Carr, Sonya C.
This paper briefly explains the possible two-mode techniques of factor analysis and discusses in more detail one two-mode technique, the Q-technique, which may be useful when the researcher is interested in obtaining information about "types" of individuals with regard to certain variables. A concrete heuristic example is used to illustrate Q-technique factor analysis. In this example, the effects of various data-collection strategies on Q-technique factor analytic results are investigated. Nine faculty members of a special education department of a large, urban university responded to 69 statements taken from an attitudes toward disabilities scale. Data were collected three times using different strategies: conventional Q-sort; mediated-ranking; and an unmarked graphic scale. The three data sets were then factor analyzed to determine the clusters or factors of subjects across the variable replicants. Principal components analysis was used to extract factors and the factors were rotated using the varimax procedure. The use of factor scores to facilitate interpretation of person factors is also illustrated. It is concluded that there are times when it is important to be concerned with clusters of people, rather than clusters of variables, and data-collection strategies should be used that facilitate meaningful interpretation. In such a case, the mediated-ranking strategy may be preferable to other data-collection strategies. Twelve data tables and four figures are provided. (Author/TJH)
