Stability of Q-Factors across Two Data Collection Methods.
Daniel, Larry G.
The purpose of the present study was to determine how two different data collection techniques would affect the Q-factors derived from several factor analytic procedures. Faculty members (N=146) from seven middle schools responded to 61 items taken from an instrument designed to measure aspects of an idealized middle school culture; the instrument is the Middle School Description Survey (MSDS). In three of the schools, the data were collected using conventional Q-sort procedures. In the remaining four schools, data were collected using an unmarked graphic scale. Separate principal components Q-technique factor analyses were used with the data collected in each school, and results were rotated to the varimax criterion. For each of the seven Q-technique analyses, factor stability was assessed by consulting the magnitude of the eigenvalue of the first factor extracted, the mean eigenvalue of all extracted factors, the average squared communality value, and the mean factor structure coefficient. Results indicate that the data collected via the unmarked graphic scale produced more stable and reliable Q-factors than did data collected via traditional Q-sort procedures. The 61 items included in the MSDS are listed. (Author/TJH)
