Trauma and substance use: the role of defences and religious engagement

Substance use disorders commonly co-occur with posttraumatic stress disorder and are associated with greater impairment. There is some evidence to suggest that different coping strategies, including defence mechanisms and religious forms of coping, may buffer the relationship between trauma and SUDs. The purpose of this study was to evaluate the potential moderating roles of defence mechanisms and religious coping on the already-established relationship between trauma symptoms and substance abuse. Data were gathered from a sample of college students (N?=?380). Trauma symptoms were associated with increased substance use and abuse. The use of immature defences was significantly associated with trauma and substance use. Increased substance abuse was also associated with higher rates of negative religious coping. Individuals who endorsed trauma symptoms were also more likely to use positive and negative religious coping. Defences and coping did not moderate the relationship between trauma and substance use.     

Credibility in the blogosphere: A study of measurement and influence of wine blogs as an information source

Uncovering what drives the consumer to action is of interest to academia and industry alike, and the advent of social media has added a confounding layer to the consumer decision process. In some ways, it has changed nothing, and in other ways, it has changed everything. Information is at the heart of decision making, and blogs offer a plethora. A positive evaluation of credibility (believability) will ultimately determine its usability for decision making. Using centered resonance analysis of wine blog writers and readers focus group data, this study attempts to address the full range of blog characteristics (subsequent scale items) that can be evaluated for credibility, anchoring them to the relevant research streams of media, website, and word of mouth. Structural equation modeling of viral blog and Twitter survey data is used to test the hypothesized scale with three dimensions—site, message, and source—for validity and also evaluate the credibility influence on behavioral intentions as mediated by trust. Evidence suggests that the author (source) is central to credibility evaluation. The data also support the influence of wine blog credibility perceptions on trust, which leads to following wine blog recommendations and continuing to participate with the wine blog.

The World at 7:00: Comparing the Experience of Situations Across 20 Countries

The purpose of this research is to quantitatively compare everyday situational experience around the world. Local collaborators recruited 5,447 members of college communities in 20 countries, who provided data via a Web site in 14 languages. Using the 89 items of the Riverside Situational Q‐sort (RSQ), participants described the situation they experienced the previous evening at 7:00 p.m. Correlations among the average situational profiles of each country ranged from r = .73 to r = .95; the typical situation was described as largely pleasant. Most similar were the United States/Canada; least similar were South Korea/Denmark. Japan had the most homogenous situational experience; South Korea, the least. The 15 RSQ items varying the most across countries described relatively negative aspects of situational experience; the 15 least varying items were more positive. Further analyses correlated RSQ items with national scores on six value dimensions, the Big Five traits, economic output, and population. Individualism, Neuroticism, Openness, and Gross Domestic Product yielded more significant correlations than expected by chance. Psychological research traditionally has paid more attention to the assessment of persons than of situations, a discrepancy that extends to cross‐cultural psychology. The present study demonstrates how cultures vary in situational experience in psychologically meaningful ways.     

Religion and Spirituality among American Indian,South Asian,Black, Hispanic/Latina,and White Women in the Study on Stress,Spirituality, and Health

Social scientists have increasingly recognized the lack of diversity in survey research on American religion, resulting in a dearth of data on religion and spirituality (R/S) in understudied racial and ethnic groups. At the same time, epidemiological studies have increasingly diversified their racial and ethnic representation, but have collected few R/S measures to date. With a particular focus on American Indian and South Asian women (in addition to Blacks, Hispanic/Latinas, and white women), this study introduces a new effort among religion and epidemiology researchers, the Study on Stress, Spirituality, and Health. This multicohort study provides some of the first estimates of R/S beliefs and practices among American Indians and U.S. South Asians, and offers new insight into salient beliefs and practices of diverse racial/ethnic and religious communities.     

Increasing relational memory in childhood with unitization strategies

Young children often experience relational memory failures, which are thought to result from immaturity of the recollection processes presumed to be required for these tasks. However, research in adults has suggested that relational memory tasks can be accomplished using familiarity, a process thought to be mature by the end of early childhood. The goal of the present study was to determine whether relational memory performance could be improved in childhood by teaching young children memory strategies that have been shown to increase the contribution of familiarity in adults (i.e., unitization). Groups of 6- and 8-year-old children were taught to use visualization strategies that either unitized or did not unitize pictures and colored borders. Estimates of familiarity and recollection were extracted by fitting receiver operator characteristic curves (Yonelinas, Journal of Experimental Psychology: Learning, Memory, and Cognition 20, 1341–1354, 1994, Yonelinas, Memory & Cognition 25, 747–763, 1997) based on dual-process models of recognition. Bayesian analysis revealed that strategies involving unitization improved memory performance and increased the contribution of familiarity in both age groups.     

Decomposing item-method directed forgetting of emotional pictures: Equivalent costs and no benefits

Using an item-method directed forgetting task, we presented negative, neutral, and positive photographic pictures, one at a time, each followed by an instruction to remember or forget. We determined that the directed forgetting effect, defined as better subsequent recognition of to-be-remembered (TBR) items than to-be-forgotten (TBF) items, was equivalent across negative, neutral, and positive pictures. To disentangle the underlying costs (i.e., decrease in memory for TBF items) and benefits (i.e., increase in memory for TBR items), we compared recognition memory performance in the directed forgetting task to that of a novel within-subjects remember-all control condition (Experiment 1) and to a between-subjects remember-all control group (Experiment 2). We observed costs without benefits across all three emotions—negative, neutral, and positive—in both experiments. These results demonstrate that equivalent directed forgetting effects for emotional stimuli are not attributable to different underlying component processes. Instead, our results suggest that selection for encoding is accomplished in similar ways, regardless of emotional content.     

Do Self-Incentives and Self-Rewards Change Behavior? A Systematic Review and Meta-Analysis

Encouraging people to self-incentivize (i.e., to reward themselves in the future if they are successful in changing their behavior) or self-reward (i.e., prompt people to reward themselves once they have successfully changed their behavior) are techniques that are frequently embedded within complex behavior change interventions. However, it is not clear whether self-incentives or self-rewards per se are effective at bringing about behavior change. Nine databases were searched alongside manual searching of systematic reviews and online research registers. One thousand four hundred papers were retrieved, spanning a range of behaviors, though the majority of included papers were in the domain of “health psychology”. Ten studies matched the inclusion criteria for self-incentive but no studies were retrieved for self-reward. The present systematic review and meta-analysis is therefore the first to evaluate the unique effect of self-incentives on behavior change. Effect sizes were retrieved from 7 of the 10 studies. Analysis of the 7 studies produced a very small pooled effect size for self-incentives (k = 7, N = 1,161), which was statistically significant, d₊ = 0.17, CI [0.06, 0.29]. The weak effect size and dearth of studies raises the question of why self-incentivizing is such a widely employed component of behavior change interventions. The present research opens up a new field of inquiry to establish: (a) whether or not self-incentivizing and self-rewarding are effective behavior change techniques, (b) whether self-incentives and self-rewards need to be deployed alongside other behavior change techniques, and, (c) when and for whom self-incentives and self-rewards could support effective behavior change.     

Development and psychometric evaluation of the Male Body Attitudes Scale (MBAS)

A measure of men's attitudes toward their body (MBAS) was developed and evaluated via three independent samples of college men. In Studies 1 and 2, factor analyses determined and cross-validated the MBAS's underlying structure. Three factors emerged from the items: muscularity, low body fat, and height. Studies 1 and 2 provided construct (i.e., convergent, concurrent, and discriminant) validity evidence for the MBAS total scale and subscales; they were related or not related as expected to drive for muscularity, body esteem, internalization of the muscular ideal, pressures for muscularity, pressures for thinness, self-esteem, body comparison, eating disorder symptomatology, and impression management. Study 3 revealed that the MBAS total score and subscale scores were stable over a 2-week period. The internal consistency reliabilities for the total score and subscale scores were high across all three studies. The MBAS should prove useful for researchers and clinicians interested in men's body image assessment.
