Profiling the "pro-environmental individual": a personality perspective

There is considerable scientific interest in the psychological correlates of pro‐environmental behaviors. Much research has focused on demographic and social‐psychological characteristics of individuals who consistently perform such actions. Here, we report the results of 2 studies in which we explored relations between broad personality traits and pro‐environmental actions. Using a wide variety of behavior and personality measures, we consistently found moderate positive relations between Openness to Experience and pro‐environmental activities in both a community sample (Study 1: N = 778) and an undergraduate student sample (Study 2: N = 115). In Study 2, we showed that the effect of Openness on pro‐environmental behaviors was fully mediated by individuals’ environmental attitudes and connection to nature. Our findings suggest that high levels of aesthetic appreciation, creativity, and inquisitiveness, but not personality traits associated with altruism, may have motivated the performance of pro‐environmental actions among our respondents. Implications for intervention development are discussed.     

The "consistency" controversy and the accuracy of personality judgments

Areas of clear and acknowledged disagreement in the personality literature's “consistency controversy” are surprisingly difficult to pin down. The present essay suggests that one basic and real disagreement nowadays is the admissability of subjective judgments of personality as data: Personologists are willing to use them, and situationists are not. Situationists generally regard judgments as so influenced by error as to be essentially unusable, and instead prefer direct measurements of specific behaviors. The relative uses and limitations of global judgments and specific measures are considered. It is concluded that any position that judgments reflect “nothing but” error is untenable. It is further concluded that each sort of data has distinct uses and limitations, provides a check on the other, and is indispensable.     

Dimensions and categories: the "big five" factors and the DSM personality disorders

The five-factor model of personality, which has been widely studied in personality psychology, has been hypothesized to have specific relevance for DSM-defined personality disorders. To evaluate hypothesized relationships of the five-factor model of personality to personality disorders, 144 patients with personality disorders (diagnosed via a structured interview) completed an inventory to assess the five-factor model. Results indicated that the majority of the personality disorders can be differentiated in theoretically predictable ways using the five-factor model of personality. However, while the personality disorders as a whole appear to be differentiable from normal personality functioning on the five factors, the patterns are quite similar across the disorders, a finding that may provide some insight into the general nature of personality pathology but may also suggest problems with discriminant validity. Third, it does not appear that considering disorders as special combinations of features (as might be expected in some categorical models) is more informative than considering them as the sum of certain features (as might be expected in a dimensional model).
