Perfectionism measures developed in English-speaking populations have become frequently used in many non-English contexts, including in Italy. Establishing structural and measurement equivalence of instruments between Canadian and Italian samples is therefore important in establishing the validity of these concepts and instruments in Italian…

The differentiation of personality by intelligence hypothesis suggests that there will be greater individual differences in personality traits for those individuals who are more intelligent. Conversely, less intelligent individuals will be more similar to each other in their personality traits. The hypothesis was tested with a large sample of…

The objective of the present study was to provide validity evidence for the scores from the Romantic Relationship Perfectionism Scale. Results indicate a two-factor structure, adequate reliability, and overall good convergent, concurrent, discriminant, and incremental validity evidence. The strengths and limitations of this measure are discussed.…

Administered the 80-item Stewart Personality Inventory (SPI) to 193 college students. Factor analysis yielded a factor structure similar to a previous study. Presents a summary of the inventory, scoring methods, and correlations of subscales to other personality inventories. Results support the SPI's validity. (BH)

Examined whether Psychopathology Checklist contains stable and replicable factor structure by factor-analyzing data from male prisoners (N=1,119) in Canada, United States, and England. Found two-factor solution replicated in all samples. Factor 1 defined by personality traits: superficiality; habitual lying/manipulation; callousness; lack of…

Presented a distinction between concepts of face validity and item subtlety. Trait categories were differentially accessible to individual judges. Higher criterion validities were associated with less subtle and more face-valid items. Results support a rational approach to test construction and emphasize the use of relevant test item content.…

Validity of the Career Maturity Inventory (CMI) was investigated using 279 grade ten and 256 grade twelve students. Factor analysis of the ten subtests of the CMI and the regression of the CMI variables on intelligence scores, sex, and grade indicated partial support of the theoretical postulations. Two principal factors emerged, but the CMI…
