Psychological Dating Violence Perpetration and Victimization: Trajectories From Middle to High School

Despite evidence documenting the negative consequences, psychological dating violence occurs frequently in adolescent dating relationships. No information exists on the trajectories that adolescents follow and their association to nonphysical peer violence. The sample comprised 624 randomly selected 6th graders. In yearly surveys from 6th through 12th grade, 550 of the 624 students reported dating at least twice during the 3 months prior to completing the survey. These students responded to questions about frequency of engagement in psychological dating violence perpetration and victimization. We used Proc TRAJ to identify developmental trajectories of behavior over time and generalized estimating equation models to examine the associations of the trajectories and peer aggression. Adolescents followed three distinct developmental trajectories related to psychological dating violence victimization and perpetration: low, increasing, and high. Based on the joint probabilities of victimization and perpetration, we identified four predominant groups: low victimization/low perpetration (LVLP; 36%), increasing victimization/increasing perpetration (40%), high victimization/high perpetration (HVHP; 15%), and increasing victimization/low perpetration (IVLP; 7%). The LVLP had significantly more boys and White students; the HVHP group had an even gender distribution and more African‐American students. For all groups, peer aggression decreased from Grade 6 to 12; students in the HVHP group reported the highest peer aggression, and students in the LVLP reported the lowest peer aggression. Findings suggest a strong, reciprocal relationship in the developmental trajectories of adolescents who experience and perpetrate psychological dating violence. Those highly engaged in these behaviors were also more likely to be violent toward peers. Aggr. Behav. 38:510‐520, 2012. © 2012 Wiley Periodicals, Inc.     

Development and Validation of the Personal Values Dictionary: A Theory-Driven Tool for Investigating References to Basic Human Values in Text

Estimating psychological constructs from natural language has the potential to expand the reach and applicability of personality science. Research on the Big Five has produced methods to reliably assess personality traits from text, but the development of comparable tools for personal values is still in the early stages. Based on the Schwartz theory of basic human values, we developed a dictionary for the automatic assessment of references to personal values in text. To refine and validate the dictionary, we used Facebook updates, blog posts, essays, and book chapters authored by over 180 000 individuals. The results show high reliability for the dictionary and a pattern of correlations between the value types in line with the circumplex structure. We found small to moderate (r_s = .1–.4) but consistent correlations between dictionary scores and self-reported scores for 7 out of 10 values. Correlations between the dictionary scores and age, gender, and political orientation of the author and scores for other established dictionaries mostly followed theoretical predictions. The Personal Values Dictionary can be used to assess references to value orientations in textual data, such as tweets, blog posts, or status updates, and will stimulate further research in methods to assess human basic values from text.     

Perceived Similarity in Multiple Categorisation

As the diversity of modern societies becomes more structurally complex, the importance of studying multiple cross-cutting group memberships increases as well. The present study investigates the causes and consequences of perceived similarity in multiple categorisation settings. In a factorial survey with six ethnic groups in Russia (N = 524 participants, 5,036 observations), this study examines the effects of eight real-life social categories (ethnicity, religion, gender, age, education level, proficiency in Russian language, job skill level, and immigration background) on perceived similarity and attitudes. The findings show that ingroup membership on each categorisation dimension increases perceived similarity with the target and that high-status others are evaluated as more similar even by participants who belong to a lower-status group. Findings also suggest that all judgments of targets fall into two clusters, which can be described as “in-group-like” and “out-group-like” others. The implications for information processing in image formation are discussed. Finally, path analysis results indicate that participants’ attitudes towards the target person are mediated by perceived similarity for all categories. These findings provide strong evidence for the large explanatory power of perceived similarity in judgments of others when multiple group memberships are salient.     

Crossed categorization outside the lab: Findings from a factorial survey experiment

Crossed categorization studies investigate intergroup attitudes in situations when two categorization dimensions are simultaneously salient, often looking at artificial groups in laboratory settings. The current study tests (a) patterns of evaluation in crossed categorization scenarios when more than two real-life categorization dimensions are crossed, and (b) the moderating role of identity importance. We conduct a factorial survey experiment with a diverse sample (N = 524), crossing eight categorization dimensions. The results provide strong support for the additive pattern of crossed categorization, challenging the view that with an increased number of categories category-based information processing will not be used. Identity importance predicts the strength of intergroup bias only on the dimension of religion, which was the dominant dimension in this sample. The study contributes to multiple and crossed categorization literature by testing some of its key assumptions using a design that increases the ecological validity of the findings.
