ABSTRACT
An evaluation is made of Goldberg s (1992) 100 Unipolar Markers of the five-factor model of personality. The factor structure of these items in samples of older men from the Normative Aging Study and undergraduate students are examined, and both item transformation and consistency testing approaches are used to evaluate replications of the five-factor structure. Results show that the five-factor structure is difficult to replicate in the sample of older men. While item transformations and sample trimming based on a consistency test did improve the quality of the replication in this older, nonstudent sample, both methods have serious drawbacks. The five-factor solution appeared in the student sample without sample trimming or data transformation. Additionally, in both student and nonstudent samples, oblique rotation resulted in inter-factor correlations relevant to more general issues in the study of trait structure. We conclude that the 100 Unipolar Markers may be unsuitable for use in older populations or with nonstudent samples.

Validation of Scheier and Carver's (1985) Life Orientation Test (LOT) has identified associations between bipolar optimism and several external constructs. However, optimism and pessimism may be not bipolar, but rather separate constructs. Furthermore, these constructs may be indistinguishable from personality traits, such as neuroticism and extraversion. This study examined the associations of separate optimism and pessimism measures with self-reports of hassles, psychological symptoms, and illness severity, controlling for personality. Ss were 1,192 men from the Normative Aging Study. Findings suggest that optimism and pessimism are separate and that their relations to external criteria remain, although attenuated, when neuroticism and extraversion are controlled.

Do spouses become more similar over time? What processes contribute to enduring similarities between them? Using the 20-year Kelly Longitudinal Study of couples, no support for the hypothesis that couples increasingly resemble each other with time was found. Rather, couples maintain the same degree of similarity across 20 years. Structural equation analyses suggest that the shared environmental experiences of couples play a significant role in maintaining these similarities over time. We distinguish the shared marital environment from the shared rearing environment and consider developmental and dynamic-relational factors that moderate the relative importance of nonshared and shared environmental experiences in life-span personality development. Whereas nonshared influences in one's family of origin contribute to development in childhood and adolescence, shared influences in one's family of destination may contribute a great deal to development in adulthood.

Consistency and change in personality development is typically studied through examination of correlations indexing the consistency of individual differences over time. Despite well-known difficulties which inherently limit this approach, few empirical efforts take advantage of alternative methods. We utilize a "person-centered" approach which permits separate and independent measurement of consistency and change for each person studied. Such measures were obtained covering four intervals between ages 3 and 18 in a longitudinally studied sample. These analyses and subsequent results extend and elaborate earlier results reported in Lives through Time (Block, 1971). It is apparent that there are wide individual differences in the degree of personality consistency and change manifested by subjects, and that the degree and timing of change permit the description of various different developmental trajectories. These pathways are described and compared to results obtained by Block (1971). This research is intended as an illustration of the possibilities obtained through person-centered approaches to the study of personality consistency and change.

In the context of a longitudinal study of cognitive and personality development, I examined various correlates of spatial visualization ability, as measured by Vandenberg's Mental Rotations Test, in order to elaborate the meaning of the known sex difference on this factor. Spatial visualization ability in females was correlated with verbal IQ and various aspects of personality. These relations were absent in males. Within each sex, measures of cognitive abilities obtained in childhood predicted spatial visualization ability at age 18. Hypotheses designed to explain the sex difference in spatial visualization must be sensitive to the different implications of this factor in males and females.
