Long-term correlated change in personality traits in old age

The present study examines long-term correlated change in personality traits in old age across a time period of 12 years. Data from the Interdisciplinary Study on Adult Development were used to investigate different aspects of personality change and stability. The sample consisted of 300 adults ranging from 60 to 64 years of age at Time 1. Personality was measured with the NEO Five-Factor Inventory. Longitudinal structural stability, differential stability, change in interindividual differences, mean-level change, and correlated change of the 5 personality traits were examined utilizing structural equation modeling. After having established strict measurement invariance, factor variances in Openness to Experience and Conscientiousness were found to be different across testing occasions, implying variant covariation patterns over time. Stability coefficients were around .70, indicating high but not perfect differential stability. The amount of interindividual differences increased with respect to Openness to Experience and Conscientiousness. Both mean-level change and stability in personality were observed. Eventually, except for Neuroticism, a number of medium effect-sized correlations among changes in personality traits emerged, implying that personality changes share a substantial amount of commonality.     

A Solution-Focused Intervention with a Youth in a Domestic Violence Situation: Longitudinal Evidence

This article reports on a 4-year therapeutic intervention combining in-person and email communication with a 13-year-old Greek-Cypriot teenager who witnessed and later was the victim of severe domestic violence. The intervention is based on an empowerment philosophy and solution-focused strategies, and its usefulness is evaluated by three standardized measures at five time points between the years 1999 and 2003. Pertinent cultural and ethical dynamics of the interventional context are highlighted. The intervention may have helped to produce better perpetrator–youth relations, remission of the client’s depression and post-traumatic stress symptoms, and improvement in his academic performance. Implications and limitations are discussed.     

Effectiveness of Cognitive/Behavioral Small Group Intervention for Reduction of Depression and Stress in Non-Hispanic White and Hispanic/Latino Women Dementia Family Caregivers: Outcomes and Mediators of Change

This study enrolled 184 middle-aged and older women (95 Non-Hispanic White and 89 Hispanic/Latino) who provided in-home hands-on care to an elderly relative with Alzheimer’s disease or another form of dementia. Within ethnic group they were randomly assigned to either a CBT-based small group intervention program called “Coping with Caregiving” (CWC) that taught a variety of cognitive and behavioral skills to reduce stress and depression, or to a minimal telephone based control condition (TSC). Intervention lasted about 4 months; one post-treatment assessment was completed 6 months after baseline by interviewers blind to the intervention condition. Interviews and interventions were conducted in English or Spanish by trained staff. Results indicated that those in the CWC (regardless of ethnicity) showed greater improvement from pre to post intervention than those in the TSC on measures of depressive symptoms, overall life stress, and caregiving-specific stress. In order to investigate if these changes may have been related to one proposed mechanism of change in CBT (skill utilization), a new measure was constructed. Change in frequency of use and perceived helpfulness of adaptive coping skills were assessed in all caregivers. Results indicated that caregivers in CWC reported greater frequency of use, and greater perceived helpfulness, of these skills at post intervention compared to caregivers in the TSC. Improvement measured by dependent measures was correlated with an increase in these indices for those in the CWC. Tests for mediation suggest that effective skill utilization may mediate the effect of treatment on outcome. Implications of these findings are discussed and recommendations provided for future research.     

Easy on the mind, easy on the wallet: The roles of familiarity and processing fluency in valuation judgments

Although people routinely estimate the value of items in their environment, from goods and services to natural resources and lost earnings following an accident, the processes that underlie human valuation estimates are not well understood. We show that people use familiarity and fluency-the ease with which they process information-to determine an item's value. In three experiments, participants believed that familiar forms of currency (e.g., a familiar $1 bill) had greater purchasing power than their unfamiliar counterparts (e.g., a rare and unfamiliar coin). Mechanistic analyses showed a positive correlation between participants' familiarity with the unfamiliar currency and their estimates of its value. We conclude by discussing the theoretical and practical implications of our findings for researchers, marketing experts, and policymakers alike.     

Validation of scales from the Deployment Risk and Resilience Inventory in a sample of Operation Iraqi Freedom veterans

The Deployment Risk and Resilience Inventory (DRRI) is a suite of scales that can be used to assess deployment-related factors implicated in the health and well-being of military veterans. Although initial evidence for the reliability and validity of DRRI scales based on Gulf War veteran samples is encouraging, evidence with respect to a more contemporary cohort of Operation Iraqi Freedom (OIF) veterans is not available. Therefore, the primary goal of the present study was to validate scales from the DRRI in a large sample of OIF army personnel diversified in occupational and demographic characteristics. In general, results supported the use of these DRRI scales in this population. Internal consistency reliability estimates were quite strong. Additionally, support was obtained for criterion-related validity, as demonstrated by associations with mental and physical health measures, and discriminative validity, as demonstrated by differences between key military subgroups.     

Publication trends in behavioral gerontology in the past 25 years: are the elderly still an understudied population in behavioral research?

The case is made that issues facing the elderly are problems of social importance that should be of interest to applied behavior analysts. An electronic review of eight prominent behaviorally‐oriented journals was conducted in order to examine the frequency of publications over the past 25 years that were concerned with issues related to aging. A total of 109 articles were devoted to aging across the eight journals, with about 30% of these involving participants with cognitive impairments. Results also indicate that each of these journals has published less than one article per year related to aging. The role behavior analysts can play in serving both the elderly and their caregivers is discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Camera perspective bias in videotaped confessions: evidence that visual attention is a mediator

Several experiments have demonstrated a camera perspective bias in evaluations of videotaped confessions: videotapes with the camera focused on the suspect lead to judgments of greater voluntariness than alternative presentation formats. The present research investigated potential mediators of this bias. Using eye tracking to measure visual attention, Experiment 1 replicated the bias and revealed that changes in camera perspective are accompanied by corresponding changes in duration of fixation on the suspect and interrogator. A path analysis indicated that visual attention partially mediated the bias, with at least one additional factor independently contributing to it. A proposed second factor was changes in available visual content that naturally coincide with alterations in camera perspective. Experiment 2 directly manipulated observers' focus and thus more conclusively established visual attention as one mediator of the camera perspective bias. Together the two experiments provide plausible evidence that differences in visual content may also mediate the bias.     

Domain-specific and domain-general changes in children's development of number comparison

The numerical distance effect (inverse relationship between numerical distance and reaction time in relative number comparison tasks) has frequently been used to characterize the mental representation of number. The size of the distance effect decreases over developmental time. However, it is unclear whether this reduction simply reflects developmental changes in domain-general speed of processing and whether it is specific to numerical compared with non-numerical magnitude. To examine these open questions, we conducted a cross-sectional study with 6-, 7-, and 8-year-old children as well as adult college students. Participants performed comparisons on Arabic numerals, arrays of squares, squares of varying luminance and bars of varying height. To control for general age-related changes in reaction time, a measure of speed of processing was used as a covariate in the analysis. A significant developmental decrease in the distance effect was found across numerical and non-numerical comparison tasks over and above general changes in processing speed. However, this change was not found to differ as a function of format. These data suggest that developmental changes in the distance effect are reflective of changes in a domain-general comparison process, rather than domain-specific developmental changes in number representations. However, analysis of overall reaction times revealed significantly greater developmental changes for numerical relative to non-numerical comparison tasks. These findings highlight the importance of taking multiple measures into account when characterizing developmental changes in numerical magnitude processing. Implications for theories of numerical cognition and its development are discussed.
