Understanding Mechanisms of Change in the Development of Antisocial Behavior: The Impact of a Universal Intervention

The association between the development of antisocial behavior, affiliation with deviant friends, and peer rejection was tested with a preventive intervention; 664 boys and girls were randomly assigned to a universal classroom-based intervention targeting disruptive behavior or a control condition. Peer nominations of antisocial behavior, friends' antisocial behavior, and peer rejection were assessed annually for 4 years. A high, a moderate, and a stable low antisocial behavior trajectory were identified. Large reductions in antisocial behavior were found among intervention children who followed the high trajectory. These reductions coincided with affiliations with nondeviant peers and with decreases in peer rejection. The affiliation between deviant and nondeviant peers was initiated by nondeviant children. The results support a causal role of deviant friends and peer rejection in the development of antisocial behavior. The implications for our understanding of the mechanisms leading to reductions in antisocial behavior are discussed.     

Perceptions of parenting: individual differences and the effect of community

Neighborhood norms are an important determinant of beliefs and attitudes about parenting, and measuring changes in community norms is an important component of evaluating community-based programs for improving child outcomes. The purpose of this study was to determine whether or not a survey of community residents' perceptions of parenting could be used to measure community parenting norms and whether these perceptions differed by individual or community characteristics. Two community surveys with 870 and 914 respondents, respectively, were conducted in 3 low-income neighborhoods. Results indicated that perceptions of parenting could be measured reliably at the community level although it is important to consider the presence of multiple norms when using such measures. Furthermore, differences in perceptions of parenting associated with individual characteristics were markedly decreased when neighborhood characteristics were considered, suggesting that the association of individual characteristics with perceptions of parenting is confounded by neighborhood characteristics.     

The Overclaiming Questionnaire: A good way to measure faking?

We evaluated the validity of the Overclaiming Questionnaire (OCQ) as a measure of job applicants’ faking of personality tests. We assessed whether the OCQ (a) converged with an established measure of applicant faking, Residualized Individual Change Scores (RICSs); (b) predicted admission of faking and faking tendencies (Faking Frequency, Minimizing Weaknesses, Exaggerating Strengths, and Complete Misrepresentation); and, (c) predicted the aforementioned measures as strongly as RICSs did. First, 261 participants were instructed to respond honesty to an extraversion measure. Next, in a mock job application, they filled out the extraversion measure again, as well as the OCQ. The OCQ only weakly predicted RICSs (r = .17), Faking Admission (r = .18), and Faking Frequency (r = .15), and it failed to correlate significantly with Minimizing Weaknesses, Exaggerating Strengths, and Complete Misrepresentation. Moreover, the OCQ performed significantly worse than RICS in predicting Faking Admission, Faking Frequency, Minimizing Weaknesses, Exaggerating Strengths, and Complete Misrepresentation. We urge caution in using the current version of the OCQ to measure faking, but speculate that the innovative approach taken in the OCQ might be more effectively exploited if the OCQ content were tailored to the specific job that applicants are being tested for.     

Evaluating Ethics Education Programs: A Multilevel Approach

Although education in the responsible conduct of research is considered necessary, evidence bearing on the effectiveness of these programs in improving research ethics has indicated that, although some programs are successful, many fail. Accordingly, there is a need for systematic evaluation of ethics education programs. In the present effort, we examine procedures for evaluation of ethics education programs from a multilevel perspective: examining both within-program evaluation and cross-program evaluation. With regard to within-program evaluation, we note requisite designs and measures for conducting systematic program evaluation have been developed and multiple measures should be applied in program evaluation. With regard to cross-program evaluation, we argue that a meta-analytic framework should be employed where analyses are used to identify best practices in ethics education. The implications of this multilevel approach for improving responsible conduct of research educational programs are discussed.     

Specifying Ability Growth Models Using a Multidimensional Item Response Model for Repeated Measures Categorical Ordinal Item Response Data

When categorical ordinal item response data are collected over multiple timepoints from a repeated measures design, an item response theory (IRT) modeling approach whose unit of analysis is an item response is suitable. This study proposes a few longitudinal IRT models and illustrates how a popular compensatory multidimensional IRT model can be utilized to formulate such longitudinal IRT models, which permits an investigation of ability growth at both individual and population levels. The equivalence of an existing multidimensional IRT model and those longitudinal IRT models is also elaborated so that one can make use of an existing multidimensional IRT model to implement the longitudinal IRT models.     

The Community Child Health Network Life Stress Interview: a brief chronic stress measure for community health research

Background and Objectives: Chronic stress is implicated in many theories as a contributor to a wide range of physical and mental health problems. The current study describes the development of a chronic stress measure that was based on the UCLA Life Stress Interview (LSI) and adapted in collaboration with community partners for use in a large community health study of low-income, ethnically diverse parents of infants in the USA (Community Child Health Network [CCHN]). We describe the instrument, its purpose and adaptations, implementation, and results of a reliability study in a subsample of the larger study cohort. Design and Methods: Interviews with 272 mothers were included in the present study. Chronic stress was assessed using the CCHN LSI, an instrument designed for administration by trained community interviewers to assess four domains of chronic stress, each rated by interviewers. Results: Significant correlations ranging from small to moderate in size between chronic stress scores on this measure, other measures of stress, biomarkers of allostatic load, and mental health provide initial evidence of construct and concurrent validity. Reliability data for interviewer ratings are also provided. Conclusions: This relatively brief interview (15 minutes) is available for use and may be a valuable tool for researchers seeking to measure chronic stress reliably and validly in future studies with time constraints.     

The value of self-report measures as indicators of driving behaviors among young drivers

Although much of the knowledge in transportation psychology has been gained by means of self-report measures, there is still a dispute regarding the usefulness and validity of such instruments. This series of two studies employed multivariate statistical models to examine associations between self-report and objective measures in two samples of young drivers. Study 1 (n = 151) compared scores on the Multidimensional Driving Style Inventory (MDSI), a self-report questionnaire tapping four broad driving styles, with the naturalistic driving recorded by an in-vehicle data recorder (IVDR). Study 2 (n = 80) compared responses to the Reckless Driving Habits Scale, assessing the frequency with which drivers commit a set of risky behaviors, with driving measures collected by a simulator. This study also examined the personality trait of sensation seeking, as well as gender and driving experience. In Study 1, the analysis revealed positive associations between high scores on the risky and hostile driving styles measured by the MDSI and risky behaviors measured by the IVDR, as well as inverse correlations between the latter and high MDSI scores on the anxious and careful driving styles. Similarly, in Study 2 associations were found between the self-reported frequency of reckless driving habits and several risky behaviors measured by the driving simulator. In addition, risky behaviors correlated with the sociodemographic variables and sensation seeking. The two studies therefore show that self-report measures are reliable tools for assessing driving behaviors for purposes of research, evaluation, and intervention.
