Self-other orientations and the Edwards Personal Preference Schedule.

Because the Edwards Personal Preference Schedule (EPPS) confounds the respondent's self and other-orientations, it was modified to measure both orientations on each of the 15 personality variables. Thirty-seven university students and their spouses were administered the modified EPPS. Their reliability was significantly higher than Edwards reports for his college student sample which was given his standard instrument. Also, the respondents were shown to have different preferences for themselves than for others, both over-all and for specific scales on the modified instrument.     

Relationships between the Vocational Preference Inventory and the Edwards Personal Preference Schedule

The Vocational Preference Inventory and the Edwards Personal Preference Schedule were administered to 372 undergraduates. The two instruments were compared using canonical analysis. The analysis revealed three significant relationships between components of the two instruments. The relationships were viewed as supportive of Holland's theory of personality types.     

The common import component scoring of the Edwards Personal Preference Schedule

Development of a new method of scoring the Edwards Personal Preference Schedule to yield component scores for each variable. Applications to clinical practice, research, and teaching are described.     

An assessment of the Edwards Personal Preference Schedule from the perspective of the five-factor model.

We examined the validity of need scales of the Edwards Personal Preference Schedule (EPPS) by correlating them with a measure of the five basic factors of personality; we also considered test format as a possible source of invalidity. Three hundred thirty (223 women, 107 men) undergraduate students completed both the NEO Personality Inventory (NEO-PI)--a measure of the five factors--and one of two versions of the EPPS. Results show that both ipsative and normative versions of the EPPS could be meaningfully interpreted within the five-factor model, although the ipsative, forced-choice format of the standard EPPS apparently lowered validity coefficients and decreased convergent and discriminant validity. We argue that the five-factor model can provide a useful interpretive context for evaluating many clinical measures.     

The Vocational Preference Inventory scores and environmental preferences

This study investigated the relationship between vocational interest as measured by the Vocational Preference Inventory and preferences of 175 undergraduates for structured or unstructured environments. Males having clear-cut preferences for structured situations had significantly higher Realistic-Conventional scores than those not having those preferences (p < .05). Additionally, males with structured preferences had significantly lower Social-Artistic scores (p < .025). Results for females were similar, but not statistically significant. Males also had significantly higher (p < .01) Realistic-Conventional scores than females. The significant relationships between VPI scores and preferences for structured and unstructured situations support Holland's contention that interest scores are expressions of personality needs.     

Right wing authoritarianism,social dominance orientation and the dimensions of generalized prejudice

Prior research suggests that individuals' prejudiced attitudes form a single generalized dimension predicted by Right Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). A dual process approach, however, expects different domains of generalized prejudice that relate differentially to RWA and SDO. To test this, 212 participants rated attitudes to 24 typically disliked groups. Factor analysis revealed three distinct generalized prejudice dimensions. Hierarchical Linear Modelling indicated that attitudes towards a ‘dangerous’ groups domain was significantly related only with RWA, attitudes toward a second ‘derogated’ groups domain was related only to SDO, and attitudes toward a third, ‘dissident’ groups, domain was significantly related to both, but powerfully with RWA and weakly with SDO. These findings have implications for explaining and reducing prejudice. Copyright © 2006 John Wiley & Sons, Ltd.     

Edwards Personal Needs: The Choice of Comparable Groups

The Edwards Personal Preference Schedule was administered to a group of men seeking help with their marriages, as well as to a comparable group of men who reported having stable marriages. When the scores of men seeking help and those of men with stable marriages are compared to Edwards' Adult Males, the number and extent of the differences are quite similar. The comparison of the men with stable marriages versus those seeking help shows relatively few differences. This study highlights the need of having an appropriate group for comparison purposes before attributing differences found to selected group variables.
