On reconciling conflicting meta-analytic findings regarding integrity test validity

We react to the Van Iddekinge, Roth, Raymark, and Odle-Dusseau (2012a) meta-analysis of the relationship between integrity test scores and work-related criteria, the earlier Ones, Viswesvaran, and Schmidt (1993) meta-analysis of those relationships, the Harris et al. (2012) and Ones, Viswesvaran, and Schmidt (2012) responses, and the Van Iddekinge, Roth, Raymark, and Odle-Dusseau (2012b) rebuttal. We highlight differences between the findings of the 2 meta-analyses by focusing on studies that used predictive designs, applicant samples, and non-self-report criteria. We conclude that study exclusion criteria, correction for artifacts, and second order sampling error are not likely explanations for the differences in findings. The lack of detailed documentation of all effect size estimates used in either meta-analysis makes it impossible to ascertain the bases for the differences in findings. We call for increased detail in meta-analytic reporting and for better information sharing among the parties producing and meta-analytically integrating validity evidence.     

Early cessation success or failure among women attempting to quit smoking: trajectories and volatility of urge and negative mood during the first postcessation week

Aversive symptoms of abstinence from nicotine have been posited to lead to smoking relapse and research on temporal patterns of abstinence symptoms confirms this assumption. However, little is known about the association of symptom trajectories early after quitting with postcessation smoking or about the differential effects of tonic (background) versus phasic (temptation-related) symptom trajectories on smoking status. The current study examined trajectories of urge and negative mood among 300 women using the nicotine patch during the first postcessation week. Ecological momentary assessments collected randomly and during temptation episodes were analyzed using hierarchical linear modeling yielding four individual trajectory parameters: intercept (initial symptom level), linear slope (direction and rate of change), quadratic coefficient (curvature), and volatility (scatter). Early lapsers, who lapsed during the first postcessation week, exhibited more severe tonic urge and phasic negative mood immediately after quitting, and more volatile tonic and phasic urge compared to abstainers. Late lapsers, who were abstinent during the first week but lapsed by 1 month, exhibited more severe tonic urge immediately after quitting compared to abstainers. These results demonstrate the importance of early postcessation urge and negative affect and highlight the value of examining both tonic and phasic effects of abstinence from nicotine.     

Reconciling conflicting electrophysiological findings on the guidance of attention by working memory

Maintaining a representation in working memory has been proposed to be sufficient for the execution of top-down attentional control. Two recent electrophysiological studies that recorded event-related potentials (ERPs) during similar paradigms have tested this proposal, but have reported contradictory findings. The goal of the present study was to reconcile these previous reports. To this end, we used the stimuli from one study (Kumar, Soto, & Humphreys, 2009) combined with the task manipulations from the other (Carlisle & Woodman, 2011b). We found that when an item matching a working memory representation was presented in a visual search array, we could use ERPs to quantify the size of the covert attention effect. When the working memory matches were consistently task-irrelevant, we observed a weak attentional bias to these items. However, when the same item indicated the location of the search target, we found that the covert attention effect was approximately four times larger. This shows that simply maintaining a representation in working memory is not equivalent to having a top-down attentional set for that item. Our findings indicate that high-level goals mediate the relationship between the contents of working memory and perceptual attention.     

Adherence across behavioral domains in treatment promoting smoking cessation plus weight control.

The authors tested whether adherence to simultaneous health behavior changes was unitary or domain specific among 76 women who modified smoking, eating, and physical activity to accomplish smoking cessation plus weight control. Random-effects regression analyses showed that adherence to both smoking and diet plans declined linearly and covaried positively; their association tended to grow stronger over time. In contrast, physical activity plan adherence did not change over time and was unrelated to other domains. At the end of treatment, 65%, 30.5%, and 25% adhered well or excellently to smoking, diet, and activity treatments, respectively. Findings support both unitary and domain-specific aspects of adherence and suggest that among smokers, smoking and eating behaviors may have similarities unshared by physical activity.     

Assessing outcome in smoking cessation studies.

Outcome measures for smoking cessation are reviewed and evaluated, including 3 self-report measures and 3 biochemical validation measures. Point prevalence reflects the percentage of participants taking action, prolonged abstinence reflects those in the maintenance stage, and continuous abstinence reflects those who progress from action to maintenance without lapsing or relapsing. Biochemical assessments are primarily measures of point prevalence abstinence. The desirability of biochemical validation is a particularly controversial and critical issue. Three factors affect the accuracy of self-report: Type of Population, Type of Intervention, and Demand Characteristics. False-negative rates are generally low. Three broad issues impact on decisions to use biochemical validation: (a) alternative explanations for false positives, (b) refusal rate problems, and (c) the effect of inaccuracy on intervention assessment.     

Attentional bias predicts outcome in smoking cessation.

Most attempts to quit smoking end in failure, with many quitters relapsing in the first few days. Responses to smoking-related cues may precipitate relapse. A modified emotional Stroop task-which measures the extent to which smoking-related words disrupt performance on a reaction time (RT) task-was used to index the distracting effects of smoking-related cues. Smokers (N = 158) randomized to a high-dose nicotine patch (35 mg) or placebo patch completed the Stroop task on the 1st day of a quit attempt. Smokers using an active patch exhibited less attentional bias, making fewer errors on smoking-related words. Smokers who showed greater attentional bias (slowed RT on the first block of smoking words) were significantly more likely to lapse in the short-term, even when controlling for self-reported urges at the test session. Attentional bias measures may tap an important component of dependence.     

Age-related trends in Stroop and conflicting motor response task findings.

Inhibition problems are reportedly at the heart of several childhood pathologies and learning disorders, but few instruments are available for their in-depth investigation. The main aim of the present study was to investigate the development of a capacity to inhibit automatic responses in young and middle childhood. For this purpose, 100 children between 6 and 11 years old were administered two tests that measure executive inhibition: an animal Stroop task (in a paper-and-pencil version of the computerized original proposed by Wright and colleagues in 2003) and a conflicting motor response task. Our results indicate that performance clearly improves in both tests during the course of a child's development and the data obtained with the paper-and-pencil animal Stroop task overlap with those obtained with the computerized version. When the task calls for a stronger inhibitory control (the incongruent situation in the Stroop task and in the opposite condition in the conflicting motor response test) the trend of the response times is less homogeneous, peaking in the youngest and oldest age brackets considered. The positivity and significance of the correlation coefficients between the two tests also suggest that the two measures are tapping cognitive abilities that are developing in a parallel fashion.     

Facilitating autonomous motivation for smoking cessation.

Physicians used either an autonomy-supportive or a controlling interpersonal style to counsel smokers based on National Cancer Institute guidelines. Physician autonomy support was rated from audiotapes, and patients' perceived competence and autonomous motivation for quitting were self-reported on questionnaires. Validated point prevalences for 6, 12, and 30 months and for continuous cessation were examined. The intervention did not have a direct effect on quit rates; however, structural equation modeling supported the self-determination process model of smoking cessation. The model indicated that the autonomy-supportive intervention was rated as more autonomy supportive, that rated autonomy support predicted autonomous motivation, and that autonomous motivation predicted cessation at all points in time. Perceived competence contributed independent variance to cessation only at 6 months.     

Body image and tobacco cessation: relationships with weight concerns and intention to resume tobacco use

Concern about weight gain after tobacco cessation is a potential barrier to quitting tobacco. Few studies, however, have examined the role of body image in cessation-related weight concerns and anticipated relapse. This study investigated relationships between current body image dissatisfaction, anticipated body image dissatisfaction (discrepancy between anticipated post-cessation body shape and desired body shape), cessation-related weight concerns, and intention to resume tobacco with weight gain. Body image dissatisfaction was significantly related to cessation-related weight concerns. Participants who reported current dissatisfaction with their body image were 2.6 times more likely to intend to resume tobacco use with cessation-related weight gain than those with no body image dissatisfaction. Individuals with anticipated body image dissatisfaction were 3.4 times more likely to intend to resume tobacco compared to individuals with no anticipated body image dissatisfaction. Women and normal weight individuals with anticipated body image dissatisfaction appear to be at particularly high risk for intending to relapse. Results suggest that tobacco cessation interventions may need to target concerns about body image as well as weight gain.     

Sex differences in predictors of adolescent smoking cessation.

Sex differences in predictors of smoking cessation were investigated among 337 male and 490 female participants in the RAND adolescent panel study. Participants reported smoking at least 11-20 times during the past year at Grade 10, with cessation defined as not smoking during the past year at Grade 12. Controlling for demographics, sex-specific analyses indicated that girls who quit smoking within 2 years had friends who smoked less frequently, perceived less parental approval of their smoking, had weaker intentions to continue smoking, used marijuana less frequently, attended fewer different schools, were more likely to have an intact nuclear family, experienced greater peer support, and rated themselves as healthier. Similar analyses for boys yielded results that were generally weaker and nonsignificant, with smoking quantity accounting for several associations in the sex-specific models. Despite these differences, interaction tests revealed significant sex differences for only three predictors. Implications of these results for understanding adolescent smoking cessation are discussed.     

Long-term psychological sequelae of smoking cessation and relapse.

The authors examined whether smoking cessation and relapse were associated with changes in stress, negative affect, and smoking-related beliefs. Quitters showed decreasing stress, increasing negative health beliefs about smoking, and decreasing beliefs in smoking's psychological benefits. Quitters became indistinguishable from stable nonsmokers in stress and personalized health beliefs, but quitters maintained stronger beliefs in the psychological benefits of smoking than stable nonsmokers. Relapse was not associated with increases in stress or negative affect However, relapsers increased their positive beliefs about smoking and became indistinguishable from smokers in their beliefs. For quitters, decreased stress and negative beliefs about smoking may help maintain successful cessation. However, for relapsers, declining health risk perceptions may undermine future quit attempts.     

Interest in smoking cessation among emergency department patients.

The authors interviewed adult patients presenting to 4 Boston emergency departments (EDs) about their smoking, quit attempts, and interest in an outpatient referral. Of the 539 patients enrolled, 26% were current smokers. Of the current smokers, 72% had tried to quit in the past year, and 34% wanted an outpatient referral. Current smokers were younger than nonsmokers and were less likely to have a high school education, primary care provider, and private insurance. The findings of this study reinforce the potential benefit of routine screening for smoking and interest in quitting in the ED. Because many underinsured Americans use the ED as a source of regular health care, the public health implications of increasing screening, counseling, and referral for smokers are substantial.     

Evidence for clinical smoking cessation for adolescents.

OBJECTIVE: This report reviews the evidence that informs the role of health and mental health care providers in addressing youth smoking cessation. DESIGN: Qualitative literature review. RESULTS: Physicians do not consistently screen adolescents for tobacco use and fail to provide recommended cessation advice. Challenges to addressing smoking cessation include the need for procedures to ensure confidentiality and the existence of competing demands to provide other services. Few published studies have specifically addressed the effectiveness of clinical interventions. Interventions that require return visits or follow-up phone contacts are technically difficult to implement in this population. Successful interventions may require resources not available in nonresearch settings. Most studies have used brief clinical intervention as a control condition, making it impossible to evaluate its effectiveness. CONCLUSION: There is little evidence that supports current clinical smoking cessation guidelines for adolescents. More research is needed to develop inexpensive, efficient clinical interventions that can provide youths access to smoking cessation help. Future challenges include reorganizing clinical systems to offer greater counseling by support staff or in electronic formats and to provide effective booster messages and follow-up care in a population that is difficult to track.     

Effects of gender in social control of smoking cessation.

This study of 93 men and 117 women smokers during an ongoing quit attempt examined the roles of gender and social network influences on quitting. For men, social influences appeared to positively affect their ability to reduce their smoking but were less effective for women. Specifically, increased reports of a spouse or partner's influence, and family and friends' influence, were associated with greater reductions in men's smoking 2 days and 4 months post quit date, respectively. In contrast, for women, greater reports of spouse or partner influence and of family and friends' influence were associated with smaller reductions in smoking. Sex differences in social control strategies and perceived autonomy supportiveness of those strategies are discussed as possible explanations for these results.     

Age-related trends in Stroop and conflicting motor response task findings

Facets of the NEO-PI-R and smoking cessation

Knowing more about the personality of smokers may help to increase the effectiveness of smoking cessation treatments and can contribute to relapse prevention. The aim of the present study was to analyze the influence of 30 specific facets of the Five-Factor Model of personality on the outcomes at the end of treatment and at 12-month follow-up, in a sample of 281 smokers seeking psychological treatment to stop smoking. Personality facets were assessed with the Revised NEO Personality Inventory (NEO-PI-R). Results showed that nicotine dependence and several facets of personality (Self-discipline, Depression, Aesthetics, Trust, and Modesty) contribute to explain short- and long-term outcomes after smoking cessation. These findings support the need of integrate information about individual smoker’s personality facets into smoking cessation programs.     

The effects of beliefs about smoking and health on smoking cessation

The purpose of this study was to examine whether beliefs of an American sample about smoking and health, as defined by cognitive orientation theory, would determine those smoking cessation program participants who would become abstainers and those who would not. Although the smoking cessation program was not designed to influence the specific kinds of beliefs studied, subscales measuring two of the four types of beliefs differentiated participants who would become abstainers from those who would not. Abstainers tended to have stronger goal beliefs about their desire to quit smoking, and stronger beliefs about the health-related implications of smoking. Participants' beliefs that they could resist an urge to smoke, which implied the use of coping skills, were more important in determining who would abstain from smoking than was their confidence that they could quit smoking, which implied the use of willpower.
