Assessing the Impact of Relative Social Position and Absolute Community Resources on Depression and Obesity Among Smokers

We tested two competing hypotheses-relative social position and community resources-in regards to their effect on two co-occurring health problems (depression, and obesity) in a sample of smokers participating in an online smoking cessation intervention. Income and education data at the zip code level from the 2000 Census was linked with individual level data. Logistic regression models were used for each co-occurring problem to determine how each SES variable (individually and interactively) was associated with the presence of co-occurring health problems. We found that lower individual education was related to poorer health for all outcomes (Depression: OR = 1.25; Obesity: OR = 1.24; Both: OR = 1.46), lower community education was only related to obesity (OR = 1.20). Lower individual income was related to higher rates of depressive symptoms (OR = 1.64) and both health problems (OR = 1.55); a significant interaction of individual and community income (Wald = 6.13, p < .05) revealed that high income individuals were less likely to be depressed if they lived in lower-income communities and became more likely to be so as community income increased. Relative social position was confirmed for depression, whereas community resources were prominent only for obesity. Higher individual education most consistently predicted positive health outcomes, making it a potentially powerful target to reduce health disparities.     

Is conflict monitoring supramodal? Spatiotemporal dynamics of cognitive control processes in an auditory Stroop task

The electrophysiological correlates of conflict processing and cognitive control have been well characterized for the visual modality in paradigms such as the Stroop task. Much less is known about corresponding processes in the auditory modality. Here, electroencephalographic recordings of brain activity were measured during an auditory Stroop task, using three different forms of behavioral response (overt verbal, covert verbal, and manual), that closely paralleled our previous visual Stroop study. As was expected, behavioral responses were slower and less accurate for incongruent than for congruent trials. Neurally, incongruent trials showed an enhanced fronto-central negative polarity wave (N_inc), similar to the N450 in visual Stroop tasks, with similar variations as a function of behavioral response mode, but peaking ~150 ms earlier, followed by an enhanced positive posterior wave. In addition, sequential behavioral and neural effects were observed that supported the conflict-monitoring and cognitive adjustment hypothesis. Thus, while some aspects of the conflict detection processes, such as timing, may be modality dependent, the general mechanisms would appear to be supramodal.     

Validation of a Spanish version of the Muscle Appearance Satisfaction Scale: Escala de Satisfacción Muscular

The psychometric properties of a Spanish version of the Muscle Appearance Satisfaction Scale (MASS; Mayville, Williamson, White, Netemeyer, & Drab, 2002) were examined using a sample of five hundred and sixty-one male weightlifters. Exploratory and confirmatory factor analyses suggested that the 19-item Spanish version of the MASS called the Escala de Satisfacción Muscular (ESM), was represented by five subscales similar to the original MASS. Internal consistency of the measure was good (α=.86-.95), and various measures of construct validity indicated that the ESM may be a useful measure of Muscle Dysmorphia symptoms among Spanish speaking populations.     

Portuguese Validation of FACES-IV in Adult Children Caregivers Facing Parental Cancer

The purpose of the present study was to examine the psychometric properties of the FACES-IV in Portuguese caregivers of cancer patients. In this cross-sectional study, a sample of 214 adult children caregivers of cancer patients receiving chemotherapy, completed FACES-IV, Family Communication Scale (FCS), Family Satisfaction Scale (FSS), and Satisfaction with Social Support Scale (SSSS). Internal consistencies above .70 were found for all FACES-IV scales, except for Enmeshed and Rigid scales, as well as for the FCS, FSS, and SSSS (except for Intimacy). Strong correlations between FACES-IV and the validation scales FCS and FSS were found except for the Enmeshed and Rigid scales. Confirmatory analysis yielded an acceptable model for the six theoretical subscales. The discriminant analysis between problematic and non-problematic family systems showed results similar to the original study. These findings suggest that FACES-IV is a valid measure of family functioning in oncological family caregiving’s contexts.     

The Emotionality Activity Sociability Temperament Survey: Factor analysis and temporal stability in a longitudinal cohort

We investigated Buss and Plomin’s Emotionality Activity Sociability (EAS) Temperament Survey for Children, used to assess temperament. Temperament is believed to comprise stable traits that change little over time. We examined stability of EAS temperament in the Avon Longitudinal Study of Parents and Children, in which 7429 mothers completed the EAS when their children were 3, 5 and 6 years old. Factor analysis was conducted at each time point, and stability over time was assessed using correlation and mixed effects regression modelling, accounting for differences within and between individuals. A four-factor model provided the best fit, with 19–20 of the 20 items loading onto the dimensions predicted by Buss and Plomin. Test–retest correlations ranged from 0.52–0.64 (3–5 years), 0.59–0.74 (5–6 years) and 0.46–0.58 (3–6 years). Mixed effects regression modelling suggested good stability over time: differences between, rather than within, individuals accounted for between 69% and 82% of the variance. This study demonstrates the stability of temperament over time, a vital pre-requisite to investigating childhood temperament as a predictor of outcomes.     

Bayesian Rationality for the Wason Selection Task? A Test of Optimal Data Selection Theory

Oaksford and Chater (1994) proposed to analyse the Wason selection task as an inductive instead of a deductive task. Applying Bayesian statistics, they concluded that the cards that participants tend to select are those with the highest expected information gain. Therefore, their choices seem rational from the perspective of optimal data selection. We tested a central prediction from the theory in three experiments: card selection frequencies should be sensitive to the subjective probability of occurrence for individual cards. In Experiment 1, expected frequencies of the p- and the q-card were manipulated independently by concepts referring to large vs. small sets. Although the manipulation had an effect on card selection frequencies, there was only a weak correlation between the predicted and the observed patterns. In the second experiment, relative frequencies of individual cards were manipulated more directly by explicit frequency information. In addition, participants estimated probabilities for the four logical cases and of the conditional statement itself. The experimental manipulations strongly affected the probability estimates, but were completely unrelated to card selections. This result was replicated in a third experiment. We conclude that our data provide little support for optimal data selection theory.     

Impact of Working Time Mismatch on Job Satisfaction: Evidence for German Workers with Disabilities

This study examines the impact of working time mismatch (i.e. the discrepancy between actual and desired working hours) on individuals’ job satisfaction by disability status in Germany. Our particular interest is in testing the assumption that working time mismatch is a more serious problem among workers with disabilities as compared to workers without disabilities, especially concerning the presence of overemployment. Using longitudinal data from the German Socio-Economic Panel (1985–2011), we estimate a “Probit Adapted OLS” model which allows us to identify the factors affecting job satisfaction for people without and with disabilities. The results indicate that all workers suffering from working time mismatch are more likely to report lower levels of job satisfaction compared to those who actually work their desired hours. In addition, all selected groups of females with disabilities prefer lower hours of work per week compared to females without disabilities. Although overemployment is clearly more harmful in terms of job satisfaction than underemployment for all workers, its impact is even higher for females with disabilities as compared to their non-disabled counterparts. From a public policy perspective, these findings show the importance of reducing working time mismatch in general and overemployment in particular among females with disabilities in order to increase their levels of job satisfaction.     

Motivational enhancement treatment in outpatient addiction centers: A multisite randomized trial

Background/Objectives: Motivational Enhancement Treatment in Spanish (METS) is a brief intervention aimed at resolving patient ambivalence towards behavior change that has demonstrated efficacy in substance use disorder treatment to reduce use and increase treatment engagement in different populations. In order to have evidence for its implementation in Mexico, a multi-site, randomized, two-arm, controlled clinical trial was conducted at three outpatient addiction treatment centers in the country to compare the effect of METS with Counseling as Usual (CAU). Method: One hundred and twenty patients were randomized to receive three sessions of METS (n = 54) or CAU (n = 66) during the first four weeks of treatment and were assessed during the following 12 weeks. Primary outcome measures were self-reported days of substance use and of treatment services utilization, which were tested using Generalized Estimating Equations. Results: Results associated both conditions with significant changes in substance use over, whereas there were no differences between conditions in substance use or in service utilization. Conclusions: Findings do not support the hypothesis that METS is more effective than CAU, but suggest that brief interventions at treatment initiation may improve patient outcomes.
