The use of reliable digits to detect malingering in a criminal forensic pretrial population

The present research is a cross-validation of previous investigation by Greiffenstein, Baker; and Gola; Greiffenstein, Gola, and Baker; and Meyers and Volbrecht on the reliable digits (RELD) method of detecting suspected malingering on the Wechsler Adult Intelligence Scale-Revised (WAIS-R). The results support the use of the RELD method on a criminalforensic pretrial population (N = 187). Sensitivities, specificities, and incremental hit ratesfor two cut levels of the RELD method, Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Infrequency and the Personality Assessment Inventory Negative Impression Scales, as well as multiple combined cut scores, were comparable to those observed in previous studies that used neuropsychologically evaluated participants. The selection of which cut score or combination of cut scores is appropriate on the RELD method is also discussed.     

Change in cognitive functioning associated with apoE genotype in a community sample of older adults

The influence of a genetic risk factor, apolipoprotein E (apoE) epsilon4 variant, was assessed in older adults aged 70 to 94 on 3 occasions over 7 years. The results of latent growth curve analyses are reported for individuals genotyped for apoE at the 2nd measurement occasion (n = 601) and for a subsample of individuals without probable or definite dementia during the 1st or 2nd occasion (n = 434). ApoE-epsilon4 status was a significant predictor of level and change in memory performance and change in speed performance in the full sample, and of initial level and change in memory performance in the nondemented subsample. These results support previous findings that apoE-epsilon4 is associated with accelerated memory deterioration in individuals without clinical dementia.     

When the central executive lets us down: schemas, attention, and load in a generative working memory task

Participants were asked to generate a single sequence of numbers in between two bounds. By varying the requested sequence length and way in which the question is posed, this paradigm enables assessment of the contributions to central executive functioning of schema, focus of attention, and load. With sequences of three or four numbers, a quarter of the sample failed fully to comply with the instructions. They generated an incorrect number of numbers or went outside the specified bounds. With sequences of six numbers, more than half of the sample infringed one or more of the constraints. Participants consistently generated sequences with particular generic properties. The overall frequency and patterns of infringements suggest that a substantial proportion of participants focused their conceptual attention on sequence content and often neglected the problem of how thelength and boundary constraints were going to be evaluated either before or during response delivery.     

Absolute Versus Tentative Interpretations: Mediating Effects of Client Locus of Control

An analog design was used to investigate the mediating effects of client locus of control (i.e., an internal focus or external focus) on perceptions of counselor style of interpreting events (i.e., absolute or tentative interpretations) on measures of perceived session depth and smoothness, and perceived counselor expertness, attractiveness, and trustworthiness. One hundred and thirty-four undergraduate college students, crossed on level of locus of control, were randomly assigned to one of two treatment conditions, and then completed measures of perceived session depth and smoothness, as well as perceived counselor expertness, attractiveness, and trustworthiness. Results indicated a significant interaction effect on perceived counselor trustworthiness. Implications for college counselors are provided.     

Persons and Substances

I have argued elsewhere that the psychological criterion of personalidentity entails that a person is not an object, but a series ofpsychological events. As this is somewhat counter-intuitive,I consider whether the psychological theorist can argue that a person, while not a substance, exists in a way that is akin to theway that substances exist. I develop ten criteria that such a`quasi-substance' should meet, and I argue that a reasonablecase can be made to show that the psychological theorist's conception of a person meets these criteria.     

Racial and Ethnic Differences in Direct-to-Consumer Genetic Tests Awareness in HINTS 2007: Sociodemographic and Numeracy Correlates

To examine the association of 1) race/ethnicity and 2) numeracy with awareness of DTC genetic tests. Secondary analysis of 6,754 Hispanic, black, and white adult respondents to the National Cancer Institute’s 2007 Health Information National Trends Survey (HINTS). Logistic regression was used to examine sociodemographic predictors of DTC genetic tests awareness including race/ethnicity, income, education, and gender. Next, two numeracy variables were added to the model. After controlling for sociodemographic variables, black respondents were significantly less likely to have heard of DTC genetic tests compared to white respondents (OR = 0.79; CI: 0.65–0.97). When numeracy variables were added to the model, the effect of black race was no longer significant (OR = 0.84; CI: 0.69–1.04). Hispanic respondents did not significantly differ from white respondents in awareness of DTC genetic tests. Other significant correlates of DTC genetic tests awareness in the full model included education, income, age, and numeracy variables including degree to which people use medical statistics and numbers to make health decisions, and preference for words or numbers when discussing “the chance of something happening.” Although black respondents were generally less aware of DTC genetic tests than white respondents, this relationship appears to be partially mediated by numeracy.     

"Do social networks explain 12-step sponsorship effects? A prospective lagged mediation analysis": Correction to Rynes and Tonigan (2011)

Reports an error in "Do social networks explain 12-step sponsorship effects? A prospective lagged mediation analysis" by Kristina N. Rynes and J. Scott Tonigan (Psychology of Addictive Behaviors, Advanced Online Publication, Sep 5, 2011, np). There is an error in the last paragraph of the Participants section. It was reported that 14.8% of the sample were Asian, however, 14.8% of the participants were American Indian or Alaskan Native and no participants were Asian. (The following abstract of the original article appeared in record 2011-20052-001.) Sponsorship is a basic and important part of the 12-step approach to recovery from substance abuse (Alcoholics Anonymous, 2005) and research has shown that having a sponsor is associated with increased involvement in 12-step programs and improved outcomes (Bond, Kaskutas, & Weisner, 2003; Tonigan & Rice, 2010). However, little is known about how sponsorship improves outcomes. Given research demonstrating bivariate associations between sponsorship and social support for abstinence (Majer, Jason, Ferrari, Venable, & Olson, 2002), we hypothesized that the association between having a sponsor and increased abstinence outcomes would be explained by increases in one's abstinence-based social network. Prospective fully lagged mediational analyses did not support this hypothesis and these results ran counter to findings of five previous studies (cf. Groh, Jason, & Keys, 2008). A review of these studies showed that researchers often used cross-sectional or partially lagged methods to test mediation and the mediational effect of the social network was small in magnitude. Results suggest that the prospective association between sponsorship and abstinence is not explained by increases in the abstinence-based social network and demonstrate the need for future studies to use rigorous and time-lagged methods to test social support for abstinence as a mediator of the effects of 12-step involvement.

Children’s Life Satisfaction: Developmental Trajectories and Environmental and Personality Predictors

Life satisfaction is a key indicator of children’s healthy development. Although the developmental changes of life satisfaction during adolescence have been investigated, the developmental trajectories of life satisfaction and related predictors during childhood remain unclear. Thus, the current study aimed to identify the developmental trajectories of life satisfaction covering the period from middle to late childhood as well as to examine the predictive roles of environmental factors (i.e., family dysfunction and basic psychological needs satisfaction at school), personality factors (i.e., neuroticism and extraversion), and their interactions in these developmental trajectories. An accelerated longitudinal design was used with Chinese elementary school students (N?=?1069, 45.8% girls, M _age?=?9.43, SD?=?0.95) of 3 cohorts (grade 3, grade 4, and grade 5) on 4 occasions at 6-month intervals. Growth mixture modeling analyses revealed three distinct trajectories of life satisfaction: “High-Stable” (88.8%), “High-Decreasing” (6.8%), and “Low-Increasing” (4.4%). Multivariate logistic regression analyses revealed that family dysfunction and neuroticism served as risk factors for adverse developmental trajectories of life satisfaction; whereas basic psychological needs satisfaction at school served as a protective factor. Furthermore, the interaction between family dysfunction and extraversion suggested that higher levels of extraversion buffered children against the negative effect of family dysfunction on the development of life satisfaction. The identification of three heterogeneous trajectory groups of children’s life satisfaction and key personality and environmental predictors associated with the trajectories suggests that specific interventions need to be tailored to the unique characteristics of the relevant trajectory groups.
