We studied the accuracy of personality impressions relying on textual information on important life domains. Specifically, how is accuracy moderated by the trait being judged, information being provided, judgeability of target persons, and perceptiveness of judges? A sample of 208 students was recruited in groups of four mutual acquaintances who described themselves and each other on a measure of the Five‐Factor Model of personality. Moreover, they wrote essays on their hobbies, friends, family, academic studies, and plans for the future and provided self‐reports on possible predictors of expressive accuracy. The essays were delivered to 130 strangers who reported their impressions of the personality of the targets and provided self‐reports on possible predictors of perceptive accuracy. Accuracy was measured by correlating these impressions with the descriptions of the targets by their acquaintances. The judges used the available information efficiently. Overall, impressions of Openness to Experience were most accurate, but accuracy depended on the information being provided. Several predictors of expressive and perceptive accuracy were identified using Biesanz's (2010) social accuracy model. The results advance our understanding of factors contributing to and moderating the accuracy of personality impressions based on textual information.

Abstract. Adult playfulness is an individual differences variable that allows people to (re-)frame everyday situations in a way to make them entertaining, stimulating, and/or interesting. Recently, a structural model with four facets (i.e., Other-directed, Lighthearted, Intellectual, and Whimsical; OLIW) and a subjective measure with 28 items have been developed. The main aim of this study is to test a 12-item short form (OLIW-S). In Study 1, we retrieved the 4-factorial OLIW structure in three independently collected samples ( N = 1,168; 696 self-ratings and 166 dyads providing reciprocal self- and peer-ratings). We found satisfactory psychometric properties for research purposes, and there was convergent and nomological validity with external measures of playfulness and the Big Five personality traits. Data from Sample 3 showed robust self-other agreement in all facets (.27–.52). In Study 2, N = 463 adults completed the OLIW-S and a measure for personality pathology (PID-5; shared variance 12–31%). A principal component analysis of the OLIW-S and PID-5 scales yielded two unique factors representing playfulness and personality pathology. Overall, our expectations were widely met and the OLIW-facets could be well located in comprehensive systems of both personality and personality pathology. Applications of the OLIW-S (e.g., large-scale assessments; zero-acquaintance studies) are discussed.

The authors studied effects of self-reported personality disorder (PD) symptoms on interpersonal perception, particularly self-other agreement and favorableness. Using a round-robin design, 52 groups of four well-acquainted students described themselves and each other on a measure of the Five-Factor model of personality and were administered a self-report screening instrument for DSM-IV (Axis 2). Using the Social Accuracy Model, the peer reports were predicted, across items, from either (a) the target person's self-reports plus the self-report item means, or (b) the items' social desirability. This resulted in separate coefficients for each peer-target dyad, indicating either self-other agreement or favorableness. These coefficients were then predicted from the PD scores of the target and the peer, using multilevel modeling. Main findings were that persons scoring high on PD measures agreed less with their peers on their unique personality characteristics, and that such persons were described by, and described their peers, less favorably.
