STATE OF SCIENCE IN INDUSTRIAL AND ORGANIZATIONAL PSYCHOLOGY: A REVIEW OF SELF-REPORTED LIMITATIONS

This study investigated self-reported limitations of published papers as an alternative and novel operationalization of the state of science of industrial and organizational (I-O) psychology. A content analysis was conducted of the reported limitations in every I-O psychology articles published in the Academy of Management Journal, the Journal of Applied Psychology, and Personnel Psychology between 1995 and 2008 (N= 2,402). Articles were coded for the number and types of limitations reported, characteristics of the research design, and topic area. Threats to internal validity were the most often reported limitations. In addition, variations were detected in the reporting of limitations over time, indicating a subtle but steady shift in the focus of I-O psychology research. Implications of these results for the science and practice of I-O psychology and for the use of self-reported limitations in scientific communication are discussed.     

Group Work with Aggressive Men: Group Within a Group Within a Group

Psychodynamic group therapy offers many opportunities for members to identify, understand, and change the underlying problems, which lead to their aggressive behavior. In addition, group therapy can help to improve the members’ interpersonal relationships. The “Coping with Aggression” is comprised of three groups. A psychodynamic group of assaultive men made up the first group. The second group consisted of two leaders and a consultant whom the group members knew about but never actually met. The observers who sat outside the group made up the third group. Therapy contracts, boundaries, and leadership, and group process are discussed.     

Cessation of alcohol and drug use among adolescents: A social learning model

This investigation tests the ability of Akers’ (1977) social learning theory of deviance to account for the cessation of alcohol or drug use among adolescents. For each of five substances, two‐group discriminant function analyses showed that social learning variables were successful in discriminating adolescents who ceased using from their counterparts who continued to use. Peer associations were generally most discriminating with normative definitions and social rewards or punishments also contributing to differentiation. Positive or negative effects of the substances as well as imitation bore little relationship to cessation. Social learning theory was as explanatory for stronger drugs as it was for alcohol and marijuana. Policy and program implications are suggested.     

Modeling multiple risks during infancy to predict quality of the caregiving environment: contributions of a person-centered approach

The primary goal of this study was to compare several variable-centered and person-centered methods for modeling multiple risk factors during infancy to predict the quality of caregiving environments at six months of age. Nine risk factors related to family demographics and maternal psychosocial risk, assessed when children were two months old, were explored in the understudied population of children born in low-income, non-urban communities in Pennsylvania and North Carolina (N = 1047). These risk factors were (1) single (unpartnered) parent status, (2) marital status, (3) mother's age at first child birth, (4) maternal education, (5) maternal reading ability, (6) poverty status, (7) residential crowding, (8) prenatal smoking exposure, and (9) maternal depression. We compared conclusions drawn using a bivariate approach, multiple regression analysis, the cumulative risk index, and latent class analysis (LCA). The risk classes derived using LCA provided a more intuitive summary of how multiple risks were organized within individuals as compared to the other methods. The five risk classes were: married low-risk; married low-income; cohabiting multiproblem; single low-income; and single low-income/education. The LCA findings illustrated how the association between particular family configurations and the infants' caregiving environment quality varied across race and site. Discussion focuses on the value of person-centered models of analysis to understand complexities of prediction of multiple risk factors.     

Schizotypal and dependent personality characteristics and managerial performance

The study of negatively connotated personality characteristics as predictors of work‐related performance is gaining momentum. While findings have generally suggested such characteristics to be negatively or curvilinearly related to performance, the current study was concerned with investigating any positive relationships that may exist between negatively connotated personality characteristics (as measured by the Hogan Development Survey) and work‐related performance in a sample of 103 Australasian financial services managers. The most notable findings from the study were that: (a) schizotypal personality characteristics positively predicted performance on a creativity competency; and (b) dependent personality characteristics positively predicted performance on a customer focus competency. Findings and limitations are discussed.     

Transitions in first-year college student drinking behaviors: does pre-college drinking moderate the effects of parent- and peer-based intervention components?

This study used Latent Transition Analysis (LTA) to examine a stage-sequential model of alcohol use among a sample of high-risk matriculating college students (N=1,275). Measures of alcohol use were collected via web-administered surveys during the summer before entering college and followed-up during the fall semester of college. Seven indicators of alcohol use were used in the LTA models, including temporal measures of typical drinking throughout the week. The results indicated that four latent statuses characterized patterns of drinking at both times, though the proportion of students in each status changed during the transition to college: (a) nondrinkers; (b) weekend nonbingers; (c) weekend bingers; and (d) heavy drinkers. Heavy drinkers were distinguished by heavy episodic drinking (HED), and increased likelihood of drinking throughout the week, especially on Thursdays. Covariates were added to the LTA model to examine the main and interaction effects of parent- and peer-based intervention components. Results indicated that participants in the parent and peer conditions were least likely to transition to the heavy drinkers status. Results also indicated that the parent condition was most effective at preventing baseline nondrinkers from transitioning to heavy drinkers whereas the peer condition was most effective at preventing escalation of use among weekend nonbingers. The results underscore the value of considering multiple dimensions of alcohol use within a person-centered approach. Differential treatment effects were found across baseline drinking class, suggesting the benefit for tailored intervention programs to reduce high-risk drinking among college students.     

Assessing the impact of group treatment for aggressive inpatients

The purpose of this research was to determine if psychodynamic group psychotherapy decreases the occurrence of physical assault by male group members. The design of the study was a randomized clinical trial. Patients assigned to the control group received the customary clinical care. Patients assigned to the Group Therapy attended a psychodynamic psychotherapy group to help them cope with their aggressive impulses. Both quantitative and qualitative measures were used. Group members showed decreased expression of anger at followup, increased effort to control anger at followup, and decline in aggressive behavior. Control subjects demonstrated no change in level of angry feelings, increased expression of anger at follow-up, decrease in effort to control anger at follow-up, and no change in aggressive behavior. A model for conducting a psychodynamic psychotherapy group for assaultive men was developed which describes process and content aspects as well as leader interventions by group phase.     

Trajectory of Adolescent Obesity: Exploring the Impact of Prenatal to Childhood Experiences

This study examined longitudinal associations of prenatal exposures as well as childhood familial experiences with obesity status from ages 10 to 18. Hierarchical generalized linear modeling was applied to examine 5,156 adolescents from the child sample of the 1979 National Longitudinal Survey of Youth. Higher maternal weight, maternal smoking during pregnancy, lower maternal education, and lack of infant breastfeeding were contributors to elevated adolescent obesity risk in early adolescence. However, maternal age, high birth weight of child, and maternal annual income exhibited long-lasting impact on obesity risk over time throughout adolescence. Additionally, childhood familial experiences were significantly related to risk of adolescent obesity. Appropriate use of family rules in the home and parental engagement in children’s daily activities lowered adolescent obesity risk, but excessive television viewing heightened adolescent obesity risk. Implementation of consistent family rules and parental engagement may benefit adolescents at risk for obesity.
