A review of research on smoking among United States Veterans with posttraumatic stress disorder (2006–2016)

Posttraumatic stress disorder (PTSD) is one of the most common psychiatric disorders diagnosed in U.S. veterans. PTSD is associated with high smoking prevalences and difficulty quitting in the general U.S. population. The current study reviewed research on smoking and PTSD in U.S. veteran samples to summarize past research and identify areas in need of additional inquiry. MEDLINE and PsycINFO searches identified papers on smoking in samples of U.S. veterans with PTSD published from January 2006 through December 2016. Thirty-four articles met all of the inclusion criteria: (a) part of the sample consisted of U.S. veterans with PTSD or PTSD symptoms, and (b) the study examined some aspect of smoking behavior. U.S. veterans with PTSD were more likely to report smoking, heavy smoking, nicotine dependence, and late-onset smoking compared to veterans without PTSD. Smoking behaviors (e.g., current smoking, heavy smoking, smoking expectancies) differed by PTSD symptoms and by combat exposure. Smoking cessation feasibility studies examined the integration of smoking treatment into PTSD clinics and found favorable outcomes. Future research on veterans with PTSD would benefit from extending topics beyond rates of smoking to better understand the treatment needs of veterans. Research on smoking-related behaviors can help identify areas to target for interventions.     

The neural correlates of alcohol-related aggression

Alcohol intoxication is implicated in approximately half of all violent crimes. Over the past several decades, numerous theories have been proposed to account for the influence of alcohol on aggression. Nearly all of these theories imply that altered functioning in the prefrontal cortex is a proximal cause. In the present functional magnetic resonance imaging (fMRI) experiment, 50 healthy young men consumed either a low dose of alcohol or a placebo and completed an aggression paradigm against provocative and nonprovocative opponents. Provocation did not affect neural responses. However, relative to sober participants, during acts of aggression, intoxicated participants showed decreased activity in the prefrontal cortex, caudate, and ventral striatum, but heightened activation in the hippocampus. Among intoxicated participants, but not among sober participants, aggressive behavior was positively correlated with activation in the medial and dorsolateral prefrontal cortex. These results support theories that posit a role for prefrontal cortical dysfunction as an important factor in intoxicated aggression.     

Braiding Two Evidence-Based Programs for Families At-Risk: Results of a Cluster Randomized Trial

Child maltreatment is a significant public health problem best addressed through evidence-based parent-support programs. There is a wide range of programs with different strengths offering a variety of options for families. Choosing one single evidence-based program often limits the range of services available to meet the unique needs of families. This paper presents findings from a study to examine the systematic braiding of two evidence-based programs, Parents as Teachers and SafeCare at Home (PATSCH), with the goal to provide a more robust intervention for higher risk families. A cluster randomized effectiveness trial was conducted to examine if PATSCH improved parenting behaviors known to decrease the risk for child maltreatment compared to Parents as Teachers (PAT) Alone. Parents (N?=?159; 92 PAT Alone; 67 PATSCH) were enrolled to complete a baseline, 6-month and 12-month assessment. Results indicate the groups did not differ on number of environmental hazards in the home, parents’ health care decision-making abilities, child abuse potential, and physical assault over time. However, with regard to the potential for child abuse, the PATSCH group showed a decrease in nonviolence discipline and increase in psychological aggression compared to the PAT group. Further research is needed to better examine this concept and its implications for the field.     

Factor Structure and Incremental Utility of the Multidimensional Cognitive Attentional Syndrome Scale (MCASS): A Bifactor Analysis

The Multidimensional Cognitive Attentional Syndrome Scale (MCASS) was developed to assess the seven maladaptive forms of self-regulation that make up the cognitive attentional syndrome (CAS). Both theory and empirical evidence highlight important distinctions among the seven forms of self-regulation underlying the CAS. The primary purpose of the present study was to determine whether the MCASS item scores are sufficiently multidimensional to warrant the use of subscale scores. A secondary aim was to examine the incremental utility of the MCASS domain-specific factors. A battery of self-report measures was administered to adults recruited through a crowd-sourcing website (N?=?359). Bifactor analysis was used to examine the multidimensionality of MCASS item scores. This analytic approach allowed for the quantification of variance captured by each domain-specific item score independent of the general factor. Results from the bifactor analysis suggest that the MCASS is a multidimensional measure, consisting of a strong general factor and domain-specific factors that are sufficiently distinct. Additionally, the majority of domain-specific factors provided incremental utility in predicting two criterion variables (i.e., general distress, happiness emotion goals) after accounting for the general factor. Taken together, results support continued use of the MCASS total scale and subscale scores and suggest that researchers may want to consider using a bifactor model when examining structural models that include the MCASS.

     

Why does ADHD Confer Risk for Cigarette Smoking? A Review of Psychosocial Mechanisms

Research has documented that adolescents and young adults with attention-deficit/hyperactivity disorder (ADHD) are at increased risk for cigarette smoking, but less attention has examined why this risk exists. The current paper reviews the literature on different psychosocial mechanisms [self-medication hypothesis, social factors (social modeling, social impairments), cognitive factors (attitudes, coping skills), and psychological variables (ADHD symptom dimensions, comorbidity)] that might explain this increased smoking risk. Results of the review suggest that, while the self-medication hypothesis has some theoretical merit, it has not been adequately examined among adolescents and young adults with ADHD. Further, cognitive and social factors may be important mechanisms that help to explain the association between ADHD and cigarette smoking, but research in these areas is sparse. Finally, a larger body of literature suggests that different psychological aspects of ADHD (e.g., comorbidity, symptom dimensions) are related to smoking. Interpretation of findings of many of these studies was hindered due to significant methodological problems and the lack of a guiding theoretical orientation. Potential theories that might facilitate future work in this area are discussed. Future research should continue to explore these important psychosocial mechanisms as well as gene–environment interactions in examining the link between ADHD and cigarette smoking.     

Creating distinct implicit and explicit attitudes with an illusory correlation paradigm

Two studies used an illusory correlation procedure to test whether distinct implicit and explicit evaluations can result from the same learning episode. All participants learned twice as much about the qualities of one group (majority) than another (minority). In one condition, the ratio of positive to negative information was equal between groups. In other conditions, the majority group showed proportionally more positive qualities than the minority group, or vice versa. Participants in the pro-majority and pro-minority conditions formed both implicit and explicit attitudes consistent with the attitude induction. Participants in the illusory correlation condition showed the expected preference for the majority group (the illusory bias), but showed no implicit preference, suggesting distinct influences on implicit and explicit attitude formation. The effects are consistent with dual-process models in which implicit attitudes reflect accounting of covariation and explicit attitudes reflect interpretative judgments of that covariation.     

Priming attachment security improves attitudes towards a range of therapies

We sought to understand how attachment orientation influenced attitudes towards different types of psychological therapies. In two studies, we (1) examined attachment orientation as a predictor of attitudes towards different therapies and (2) tested whether attachment security priming could improve attitudes. Study 1 (n = 339) found associations between attachment orientation and attitudes towards, and likelihood of using different therapies. Positive and negative attitudes about different therapies mediated the relationship between attachment avoidance and likelihood of use. Study 2 (n = 412) showed that primed security (vs. neutral prime) improved attitudes towards relational, non‐relational and distanced‐relational therapies for those with a fearful‐avoidant attachment orientation. For relational and distanced‐relational therapies, the mechanism of this effect was increased cognitive openness. Attachment orientation is a determinant of therapy attitudes and anticipated help‐seeking behaviour. Priming security may promote open‐minded decision‐making about some therapies. Findings are discussed with relevance to attachment theory, research and clinical practice.     

The time course of negative repetition effects in post-cue naming

It has previously been shown that when picture pairs are repeated across blocks in a post-cue naming task, former distractors are named faster than former targets: the “negative repetition effect” (Mayall, Humphreys, & Kotsanis, 2002). In the present study the time course of this effect was examined. Experiment 1 demonstrated that the effect became apparent after a lag of only two intervening trials, with former targets being named faster than former distractors after a lag of zero trials. Experiment 2 used a new baseline condition with repeated picture pairs for which no response was required on the first presentation. Comparisons with this baseline indicated that the negative repetition effect is the result of suppression of former targets as opposed to facilitation of former distractors. The results support the proposal of Mayall et al. that the negative repetition effect reflects a form of speech monitoring that is applied when there is competition in the process of mapping from semantics to name representations.
