Trajectories of Big Five Personality Traits: A Coordinated Analysis of 16 Longitudinal Samples

This study assessed change in self-reported Big Five personality traits. We conducted a coordinated integrative data analysis using data from 16 longitudinal samples, comprising a total sample of over 60 000 participants. We coordinated models across multiple datasets and fit identical multi-level growth models to assess and compare the extent of trait change over time. Quadratic change was assessed in a subset of samples with four or more measurement occasions. Across studies, the linear trajectory models revealed declines in conscientiousness, extraversion, and openness. Non-linear models suggested late-life increases in neuroticism. Meta-analytic summaries indicated that the fixed effects of personality change are somewhat heterogeneous and that the variability in trait change is partially explained by sample age, country of origin, and personality measurement method. We also found mixed evidence for predictors of change, specifically for sex and baseline age. This study demonstrates the importance of coordinated conceptual replications for accelerating the accumulation of robust and reliable findings in the lifespan developmental psychological sciences. © 2020 European Association of Personality Psychology     

Group Intensive Family Training (GIFT) for preschoolers with autism spectrum disorders

Early, intensive behavioral intervention is effective in treating children with autism spectrum disorders (ASDs), but can be cost prohibitive. Expenses may be defrayed if children can benefit from parents acting as therapists. This quantitative case series examines the efficacy of the Group Intensive Family Training (GIFT) program, a 12‐week (180 h, delivered 3 h each weekday) parent‐training for preschoolers with ASDs. Parents were individually mentored in the hands‐on application of behavior analytic techniques, implementing these skills in vivo within a group of six parent–child dyads. Seventy‐two parents and children (ages 25–68 months) with ASDs participated in this study. Children's cognitive and adaptive functioning was assessed before and after the intervention program. Analyses revealed average gains of eight standard score points on the Mullen Early Learning Composite and five standard score points on the Vineland Adaptive Behavior Composite after 12 weeks of treatment. Additionally, 14% and 11% of the children moved from the ‘impaired’ to ‘non‐impaired’ range on Mullen and Vineland composite scores, respectively. This preliminary investigation suggests that GIFT's behavioral, group parent‐training can lead to significant, yet cost‐ and time‐efficient gains for children with ASDs. Results must be interpreted with caution because of the absence of a control group. Copyright © 2008 John Wiley & Sons, Ltd.     

A Best Practices Guide to Intersectional Approaches in Psychological Research

This paper serves as a “best practices guide” for researchers interested in applying intersectionality theory to psychological research. Intersectionality, the mutually constitutive relations among social identities, presents several issues to researchers interested in applying it to research. I highlight three central issues and provide guidelines for how to address them. First, I discuss the constraints in the number of identities that researchers are able to test in an empirical study, and highlight relevant decision rules. Second, I discuss when to focus on “master” identities (e.g., gender) versus “emergent” identities (i.e., White lesbian). Third, I argue that treating identity as a process situated within social structural contexts facilitates the research process. I end with a brief discussion of the implications for the study of intersectionality.     

Posttraumatic growth in trauma survivors: Implications for practice

The study of positive sequelae to trauma is increasingly a focus of attention in the trauma research literature. This paper describes the construct of posttraumatic growth, a phenomenon that involves positive changes and benefits gained through coping with traumatic experiences. Variables associated with posttraumatic growth are summarized. Specific interventions for counselling psychology practice are described.     

Group Therapy with Native Americans: Understanding Essential Differences

Many issues for Native Americans are different from those of other minority groups. This article will discuss the legacy of forced assimilation, historic distrust, the diversity among American Indians, and how these issues affect treatment. Group therapy will be explored, including Native American approaches to groups, homogeneous groups, and racially heterogeneous groups. Preparation for heterogeneous groups and issues that may arise are included.     

Cohort differences in cognitive aging and terminal decline in the Seattle Longitudinal Study

Life span researchers have long been interested in how and why fundamental aspects of human ontogeny differ between cohorts of people who have lived through different historical epochs. When examined at the same age, later born cohorts are often cognitively and physically fitter than earlier born cohorts. Less is known, however, about cohort differences in the rate of cognitive aging and if, at the very end of life, pervasive mortality-related processes overshadow and minimize cohort differences. We used data on 5 primary mental abilities from the Seattle Longitudinal Study (Schaie, 2005) to compare both age-related and mortality-related changes between earlier born cohorts (1886-1913) and later born cohorts (1914-1948). Our models covary for several individual and cohort differences in central indicators of life expectancy, education, health, and gender. Age-related growth models corroborate and extend earlier findings by documenting level differences at age 70 of up to 0.50 SD and less steep rates of cognitive aging on all abilities between 50 and 80 years of age favoring the later born cohort. In contrast, mortality-related models provide limited support for positive cohort differences. The later born cohort showed steeper mortality-related declines. We discuss possible reasons why often reported positive secular trends in age-related processes may not generalize to the vulnerable segment of the population that is close to death and suggest routes for further inquiry.     

Drivers’ decision to speed: A study inspired by the theory of planned behavior

Using structural equation modeling (LISREL 8.71), drivers’ everyday speeding behavior was predicted using the theory of planned behavior as a frame of reference. One hundred and twelve test drivers had a device installed in their vehicles that continuously logged their speeding behavior in a large area under an extended period of time. The test drivers also completed a questionnaire including questions inspired by the theory of planned behavior. It was found that the independent variables stipulated in the theory afforded a level of prediction of drivers’ self-reported speeding as well as of their logged speeding. Attitude towards speeding, subjective norm, and perceived behavioral control were significant determinants of self-reported speeding. Self-reported speeding, and subjective norm, but not perceived behavioral control, did then contribute to the prediction of drivers’ logged speeding. The fact that perceived behavioral control did not directly contribute to the prediction of drivers’ logged speeding may be due to the possibility that drivers with several years of experience already take into account the actual control they have over the target behavior. As the theory of planned behavior can be used as a frame of reference to predict drivers’ everyday speeding behavior, it is suggested that the drivers might decide on a target behavior and in living up to this decision they continuously monitor their target speed during everyday driving.     

Family stressors as predictors of codependency

Codependency has been defined as an extreme focus on relationships, caused by a stressful family background (J. L. Fischer, L. Spann, & D. W. Crawford, 1991). In this study the authors assessed the relationship of the Spann-Fischer Codependency Scale (J. L. Fischer et al., 1991) and the Potter-Efron Codependency Assessment (L. A. Potter-Efron & P. S. Potter-Efron, 1989) with self-reported chronic family stress and family background. Students (N = 257) completed 2 existing self-report codependency measures and provided family background information. Results indicated that women had higher codependency scores than men on the Spann-Fischer scale. Students with a history of chronic family stress (with an alcoholic, mentally ill, or physically ill parent) had significantly higher codependency scores on both scales. The findings suggest that other types of family stressors, not solely alcoholism, may be predictors of codependency.     

Does teaching an omnibus mand preclude the development of specifying mands?

When problem behavior is controlled by a synthesized reinforcement contingency, a simple omnibus mand that yields access to all reinforcers simultaneously has been shown to effectively replace problem behavior. The question arises as to whether teaching an omnibus mand will preclude the acquisition of specifying mands for each of the combined reinforcers. In this study, after 3 students diagnosed with autism acquired an omnibus mand (“My way, please”) that yielded all identified reinforcers simultaneously, specifying mands (e.g., “All done,” “May I have my toys?” “Play with me”) were taught to yield each individual reinforcer (e.g., escape, tangibles, attention). Problem behavior was immediately eliminated for all children, and the omnibus mand was acquired quickly. Teaching an omnibus mand did not preclude acquisition of specifying mands for any learner and instead allowed for the acquisition of specifying mands once problem behavior had been effectively reduced.
