Expectations for reporting factor analysis results as part of construct validation are explored in the context of emerging views of measurement validity. Desired practices are discussed for both exploratory and confirmatory factor analysis. A short computer program for conducting parallel analysis is included. (Author/SLD)

Research libraries are increasingly supplementing collection counts with perceptions of service quality as indices of status and productivity. The present study was undertaken to explore the reliability and validity of scores from the SERVQUAL measurement protocol (A. Parasuraman and others, 1991), which has previously been used in this type of…

Editorial board members of "Educational and Psychological Measurement" were asked to list up to five publications each, written since roughly 1950, that they thought were seminal to shaping the measurement field. This bibliography lists 59 of their selections as a "hit parade" of measurement readings. (SLD)

This study was conducted to evaluate whether the adjectival self-description checklist may provide a viable method of quickly obtaining initial personality type information. The Personal Preferences Self-Description Questionnaire (PPDSQ) was administered to more than 420 college students, and data were analyzed using classical reliability analysis…

The SERVQUAL measure was developed by A. Parasuraman, L. Berry, and V. Zeithaml (1988) to measure perceptions of service quality, originally in the retailing sector. However, libraries and other educational institutions are also service providers. Librarians in particular have increasingly become interested in measuring quality of service as the…

The utility of combining confirmatory factor analysis and second-order methods is illustrated in a study of responses of 487 undergraduate and graduate students to the love instrument of C. Hendrick and S. Hendrick. Second-order confirmatory methods allow the researcher to explore complex realities more thoroughly. (SLD)

The application and utility of confirmatory second-order factor analytic methods are discussed. Factor analysis is central to concerns regarding measurement validity. Confirmatory methods are especially useful because they explicitly consider measurement error influences and because the methods are inherently theory-driven and theory-oriented.…

The present study investigated the factor structure underlying responses to a measure of psychological type, the Personal Preferences Self-Description Questionnaire (PPSDQ). Measures of psychological type have been extremely useful in various applications, including career counseling and in assessing learning styles. Subjects were 422 university…

Investigated the psychometric integrity of scores from the LibQUAL+ evaluation of perceived library service quality conducted by ARL (Association of Research Libraries). Examines score structure, score reliability, score correlation and concurrent validity coefficients, scale means, and scale standardized norms, and considers the potential of the…

The Myers-Briggs Type Indicator (MBTI) is one of the most frequently used measures of personality. MBTI Form G and a self-descriptive adjectival checklist, the "Personal Preferences Self-Description Questionnaire" (PPSDQ), were administered to 191 college students. The four dimensions of personality measured by the MBTI are:…
