A latent class factor approach to identifying subtypes of juvenile diversion youths based on psychopathic features

Latent class factor analysis allows for the estimation of a dimensional construct such as psychopathy through factor analysis while also examining the heterogeneity of the sample. We report the results of a latent class factor analysis examining the psychometric structure of a widely used measure of psychopathy, as well as internalizing (i.e. anxiety) and externalizing indices, among diversion program youths involved in an intervention study. The results indicated that four subgroups of adolescents existed in the data: one with high psychopathic features and externalizing problems, but low anxiety; one with moderately high affective and behavioral psychopathic features and externalizing problems, but low anxiety; one with moderately high interpersonal and behavioral psychopathic features, externalizing problems, and anxiety; and one with very low psychopathy scores, anxiety, and externalizing problems. The validity of these subgroups was assessed comparing prior family problems, substance use, and offending measures, and one‐year follow‐up measures of recidivism, detention days, substance use, and program completion. This study offers partial support for the existence of psychopathy subgroups and has implications for future studies of psychopathy typologies. In addition, this study employed a methodology for classification that permits consideration of the dimensional nature of a construct, and as such has implications for a variety of research areas.

career awareness of new graduates and recruiting activities by companies in japan

Japan has been experiencing a labor market problem wherein many young people are leaving their jobs within the first 3 years. The authors explore this situation and consider the role of career development in this process. Suggestions are made for how career development programs can play an important role in facilitating a more satisfying career transition process.     

Rasch calibration of a unidimensional perfectionism inventory for sport

ObjectiveThe purposes of this study were to generate and calibrate a unidimensional sports perfectionism scale for competitive athletes using the Rasch model, and validate the scale through the convergent and known-difference validity approach.MethodThe instrument, called the Sport Perfectionism Scale (SPS), was administered to 323 undergraduate students at a university in the southeastern U.S., ranging in age from 17 to 44 yrs, who previously competed on their high school team or currently compete at the intercollegiate level.ResultsUsing the Rasch model, the level of item difficulty (i.e., most and least difficult) and the athlete's level (i.e., intensity) of perfectionism were estimated. Model-data fit was determined by Infit and Outfit statistics (≥0.5 and ≤1.5). With the exception of one item, the model fits the data well. Rasch analysis supported the measure of perfectionism in sport as a unidimensional construct. Data from the SPS were positively related with those from Stoeber, Otto, Pescheck, Becker, and Stoll's ([2007]. Perfectionism and competitive anxiety in athletes: differentiating striving for perfection and negative reactions to imperfection. Personality and Individual Differences, 42, 959–969.) Perfectionism During Competitions measure (r = 0.63), and there was a significant difference in athlete's perfectionism between levels of competition, F (3, 314) = 5.21, p = 0.002, partial eta-squared, 0.05. This result supports convergent and known-difference evidence of validity for the SPS.ConclusionsThese results lend credence to using the Rasch model as a unique approach to validate evidence of perfectionism as a unidimensional construct in competitive sport.     

The impact of aggressive priming, rumination, and frustration on prison sentencing

We tested the hypothesis that ruminating about a previous aggressive prime interacts with a subsequent minor frustration to augment aggression. Sixty participants watched a video showing a murder during a bank robbery (the aggressive prime). Those in the rumination condition were asked to write about the video for 20 min. In the no rumination condition, participants were given 20 min to complete an irrelevant task. Participants were then either frustrated or not frustrated. Our results supported the main hypothesis. Relative to the control condition, neither rumination nor frustration alone impacted aggression. Rumination, in combination with a minor frustration, however, increased the recommended prison sentence towards the targets. We discuss the implications of our findings.     

The Normative Structure of Adjudicative Dialogue

Resolution-oriented dialogue has a normative structure that is largely subject to theoretical explication. This paper develops a simple model that sheds light on how moves in a reason-giving game alter the distribution of discursive commitments and entitlements. By clarifying the practice of deontic scorekeeping, we can enhance our collective capacity to resolve conflicts dialogically.     

Validating self-report measures of state and trait anxiety against a physiological measure

While anxiety research frequently uses only self-report measures to assess dimensions of state and trait anxiety, the present study sought to corroborate these self-report measures using a physiological measure, namely heart rate. Another aim of the present study was to test the multidimensional interaction model of anxiety in a social evalua-tion situation (i.e., a seminar presentation), using a physiological measure of state anxiety. Graduate psychology students completed a state anxiety questionnaire and were attached to a heart rate recorder prior to a class seminar presentation. One week later, students completed trait and state anxiety questionnaires and were again at-tached to a heart rate recorder prior to seminar observation by others. Heart rate was elevated during seminar presentation relative to seminar observation, reached maxi-mum values during the first 15 minutes of seminar presentation and then decreased over time. State anxiety scores indicate that participants were experiencing consider-ably more anxiety just before presenting the seminar than just before observing a seminar. Heart rate during seminar presentation was significantly correlated with self-report state anxiety and self-report social evaluation trait anxiety, but not with seminar grade. Support was found for the multidimensional interaction model of anxiety using the physiological measure (i.e., heart rate).
