Discriminant validity assessment has become a generally accepted prerequisite for analyzing relationships between latent variables. For variance-based structural equation modeling, such as partial least squares, the Fornell-Larcker criterion and the examination of cross-loadings are the dominant approaches for evaluating discriminant validity. By means of a simulation study, we show that these approaches do not reliably detect the lack of discriminant validity in common research situations. We therefore propose an alternative approach, based on the multitrait-multimethod matrix, to assess discriminant validity: the heterotrait-monotrait ratio of correlations. We demonstrate its superior performance by means of a Monte Carlo simulation study, in which we compare the new approach to the Fornell-Larcker criterion and the assessment of (partial) cross-loadings. Finally, we provide guidelines on how to handle discriminant validity issues in variance-based structural equation modeling.

A new criterion for assessing discriminant validity in variance-based structural equation modeling

Amazon's Mechanical Turk (MTurk) is a relatively new website that contains the major elements required to conduct research: an integrated participant compensation system; a large participant pool; and a streamlined process of study design, participant recruitment, and data collection. In this article, we describe and evaluate the potential contributions of MTurk to psychology and other social sciences. Findings indicate that (a) MTurk participants are slightly more demographically diverse than are standard Internet samples and are significantly more diverse than typical American college samples; (b) participation is affected by compensation rate and task length, but participants can still be recruited rapidly and inexpensively; (c) realistic compensation rates do not affect data quality; and (d) the data obtained are at least as reliable as those obtained via traditional methods. Overall, MTurk can be used to obtain high-quality data inexpensively and rapidly.

Amazon's Mechanical Turk A New Source of Inexpensive, Yet High-Quality, Data?

Five studies tested two general hypotheses: Individuals differ in their use of emotion regulation strategies such as reappraisal and suppression, and these individual differences have implications for affect, well-being, and social relationships. Study 1 presents new measures of the habitual use of reappraisal and suppression. Study 2 examines convergent and discriminant validity. Study 3 shows that reappraisers experience and express greater positive emotion and lesser negative emotion, whereas suppressors experience and express lesser positive emotion, yet experience greater negative emotion. Study 4 indicates that using reappraisal is associated with better interpersonal functioning, whereas using suppression is associated with worse interpersonal functioning. Study 5 shows that using reappraisal is related positively to well-being, whereas using suppression is related negatively.

Individual differences in two emotion regulation processes: implications for affect, relationships, and well-being.

This study investigated the relation of the “Big Five” personality dimensions (Extraversion, Emotional Stability, Agreeableness, Conscientiousness, and Openness to Experience) to three job performance criteria (job proficiency, training proficiency, and personnel data) for five occupational groups (professionals, police, managers, sales, and skilled/semi-skilled). Results indicated that one dimension of personality, Conscientiousness, showed consistent relations with all job performance criteria for all occupational groups. For the remaining personality dimensions, the estimated true score correlations varied by occupational group and criterion type. Extraversion was a valid predictor for two occupations involving social interaction, managers and sales (across criterion types). Also, both Openness to Experience and Extraversion were valid predictors of the training proficiency criterion (across occupations). Other personality dimensions were also found to be valid predictors for some occupations and some criterion types, but the magnitude of the estimated true score correlations was small (ρ < .10). Overall, the results illustrate the benefits of using the 5-factor model of personality to accumulate and communicate empirical findings. The findings have numerous implications for research and practice in personnel psychology, especially in the subfields of personnel selection, training and development, and performance appraisal.

The big five personality dimensions and job performance: a meta-analysis

2 Taxonomy is always a contentious issue because the world does not come to us in neat little packages (S. Personality has been conceptualized from a variety of theoretical perspectives, and at various levels of Each of these levels has made unique contributions to our understanding of individual differences in behavior and experience. However, the number of personality traits, and scales designed to measure them, escalated without an end in sight (Goldberg, 1971). Researchers, as well as practitioners in the field of personality assessment, were faced with a bewildering array of personality scales from which to choose, with little guidance and no overall rationale at hand. What made matters worse was that scales with the same name often measure concepts that are not the same, and scales with different names often measure concepts that are quite similar. Although diversity and scientific pluralism are useful, the systematic accumulation of findings and the communication among researchers became difficult amidst the Babel of concepts and scales. Many personality researchers had hoped that they might devise the structure that would transform the Babel into a community speaking a common language. However, such an integration was not to be achieved by any one researcher or by any one theoretical perspective. As Allport once put it, " each assessor has his own pet units and uses a pet battery of diagnostic devices " (1958, p. 258). What personality psychology needed was a descriptive model, or taxonomy, of its subject matter. One of the central goals of scientific taxonomies is the definition of overarching domains within which large numbers of specific instances can be understood in a simplified way. Thus, in personality psychology, a taxonomy would permit researchers to study specified domains of personality characteristics, rather than examining separately the thousands of particular attributes that make human beings individual and unique. Moreover, a generally accepted taxonomy would greatly facilitate the accumulation and communication of empirical findings by offering a standard vocabulary, or nomenclature. After decades of research, the field is approaching consensus on a general taxonomy of personality traits, the " Big Five " personality dimensions. These dimensions do not represent a particular theoretical perspective but were derived from analyses of the natural-language terms people use to describe themselves 3 and others. Rather than replacing all previous systems, the Big Five taxonomy serves an integrative function because it can represent the various and diverse systems of personality …

The Big Five Trait taxonomy: History, measurement, and theoretical perspectives.

The effects of intergroup contact on stereotypic beliefs, it is argued, depend upon (1) the potential susceptibility of those beliefs to disconfirming information and the degree to which the contact setting “allows” for disconfirming events, and (2) the degree to which disconfirming events are generalized from specific group members to the group as a whole. To account for the generalization of attributes from a sample to a population, we present a cognitive-processing model. The model assumes that impressions of groups are most heavily influenced by the attributes of those members most strongly associated with the group label. In order for group stereotypes to change, then, disconfirming information must be associated with the group labels. However, a number of powerful cognitive processes work against this association. As a consequence, we predict that stereotype change will be relatively rare under “normal” circumstances but may occur when disconfirming information is encountered under circumstances that activate the group label (e.g., when disconfirming attributes are associated with otherwise typical group members).

Social categorization and behavioral episodes: A cognitive analysis of the effects of intergroup contact.

The authors propose that people in relationships become emotionally similar over time--as this similarity would help coordinate the thoughts and behaviors of the relationship partners, increase their mutual understanding, and foster their social cohesion. Using laboratory procedures to induce and assess emotional response, the authors found that dating partners (Study 1) and college roommates (Studies 2 and 3) became more similar in their emotional responses over the course of a year. Further, relationship partners with less power made more of the change necessary for convergence to occur. Consistent with the proposed benefits of emotional similarity, relationships whose partners were more emotionally similar were more cohesive and less likely to dissolve. Discussion focuses on implications of emotional convergence and on potential mechanisms.

The lexical approach to personality: A historical review of trait taxonomic research

The relation between self-concept differentiation (SCD), the tendency to see oneself as having different personality characteristics in different social roles, and psychological adjustment was examined in a sample of college students and a sample of middle-aged women. In both studies, Ss with high levels of SCD showed poor emotional adjustment (e.g., depression) and tended to reject social norms and conventions (e.g., low socialization). Longitudinal analyses demonstrated that these same characteristics measured at age 21 predicted SCD measured more than 30 years later in middle age. These findings provide strong evidence that SCD is a sign of fragmentation of the self rather than specialization of role identities. The social context was also an important determinant of SCD; both dissatisfaction with role performance and frequent role changes in relationships and jobs predicted SCD measured 9 years later.

The Divided Self: Concurrent and Longitudinal Effects of Psychological Adjustment and Social Roles on Self-Concept Differentiation

We examined several determinants of interjudge agreement on personality traits. The findings, which were cross-validated in two samples, suggest that agreement is a function of four factors: which Big Five content domain the trait represents, how observable relevant behaviors are, how evaluative the trait is, and whether the self is one of the judges. Agreement was highest for traits related to Extraversion and lowest for traits related to Agreeableness. More observable and less evaluative traits elicited higher interjudge agreement. On average, self-peer agreement was lower than peer-peer agreement. However, this effect was limited to evaluative traits; for neutral traits, self-peer agreement was as high as peer-peer agreement. These findings suggest that self- and peer perception proceed through similar processes for neutral traits but not for highly evaluative traits, raising the possibility that self-perceptions become distorted when the trait is affectively charged.
