Extending the Acquired Preparedness model of binge eating: Testing the indirect effects of high-risk personality traits on binge eating via positive and negative reinforcement expectancies

The association of alcohol use and positive and negative urgency to same day objective binge eating in emerging adults

Introduction

Objective binge eating and problematic alcohol use often co-occur and are common behaviors in emerging adults. Both behaviors are thought to be driven by affect regulation processes. Objective binge eating often occurs in the context of increasing or acute negative affect, and often occurs in solitude. Alcohol use in emerging adults can also be associated with negative affect regulation. However, in contrast to objective binge eating, a large body of research indicates that there are positively valenced pathways to alcohol use in this age group. Emerging adults often drink socially, to enhance enjoyment, and in the context of positive mood. We propose that one pathway to objective binge eating in this developmental period is through alcohol use itself, such that emerging adults who consume alcohol and who are more likely to act impulsively in the context of positive emotion (i.e., have high levels of positive urgency) may be more likely to binge eat following drinking.

Methods

We collected data using ecological momentary assessment in 106 undergraduates on positive and negative affect, motives for drinking and eating, and alcohol use and objective binge eating, in addition to baseline questionnaires of impulsivity.

Results

There were no significant changes in affect prior to drinking in this sample. Alcohol use at one time point significantly increased odds of objective binge eating at a later time point in the same day. Individual differences in positive urgency, the tendency to act rashly while experiencing positive affect, were also associated with increased odds of objective binge eating that occurred after alcohol use. Individual differences in negative urgency, the tendency to act rashly after experiencing negative affect, did not have a main effect on objective binge episodes, but did interact with alcohol use to increase the odds of objective binge eating following drinking. The vast majority of drinking episodes prior to objective binge eating were social drinking episodes, and participants most commonly endorsed "to have fun" as a reason for drinking.

Discussion

Results suggest that alcohol consumption may increase risk for objective binge eating in emerging adults.

Eating expectancies among trauma-exposed Latinx college students: The role of mindful attention

Objective: Emergent research suggests that trauma-exposed Latinx college students are a particularly at-risk group for eating-related problems. For this reason, there is a need to further understand the cognitive processes that may underpin maladaptive eating among this vulnerable segment of the population. Participants: Participants included 304 trauma exposed Latinx college students (84.5% females; Mage = 22.8 years, SD = 5.79). Methods: The current study examined the role of mindful attention in relation to several distinct expectancies related to eating. Results: Results indicated that lower reported levels of mindful attention were associated with greater levels of expectancies of eating to help manage negative affect, expectancies that eating will alleviate boredom, and expectancies that eating will lead to feeling out of control. Conclusions: These findings suggest that it may be beneficial to assess for mindful attention among Latinx college students with a history of trauma exposure presenting with problematic eating behaviors.

Reward sensitivity, eating behavior, and obesity-related outcomes: A systematic review

INTRODUCTION

Previous research has identified reward sensitivity as an important factor that may contribute to the engagement in eating behavior (e.g., binge eating, emotional eating, etc.) and increase obesity risk. In the current study, we conducted a systematic review of the literature to determine the relationships between reward sensitivity, eating behavior, and obesity-related outcomes. The study focused on two commonly used measures of reward sensitivity in the literature: the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ) and the Behavioral Inhibition Scale/Behavioral Activation Scale (BIS/BAS Scale).

METHOD

We conducted a systematic search to identify studies that analyzed reward sensitivity as a predictor of eating behavior or obesity-related outcomes, and measured reward sensitivity using the SPSRQ or BIS/BAS Scale. The search yielded N=19 total publications included in the review.

RESULTS

Findings indicated that reward sensitivity, primarily measured by summary scores on the SPSRQ or BIS/BAS Scale, were positively associated with a variety of eating behaviors and obesity-related outcomes with small to moderate effect sizes. Findings were most consistent across studies that examined the association between reward sensitivity and eating behavior outcomes (e.g., binge eating, emotional eating) (r values= .08 to .41; p values < .001 to p < .05) and food consumption outcomes (e.g., palatable food intake) (r values = .21 to .40; p < .001 to p values < .05). Findings were less consistent for food craving and BMI outcomes, and revealed these relationships may depend on individual-level factors and/or environment-related factors, (e.g., food cues). A quality evaluation using the Critical Appraisal Tool for Cross-Sectional Studies (AXIS tool) indicated that most studies were rated as moderate to strong quality (84%).

CONCLUSION

Findings indicate that elevated reward sensitivity may be a risk factor for engagement in eating behaviors that may increase obesity risk.

Pathways of personality and learning risk for addictive behaviors: A systematic review of mediational research on the Acquired Preparedness model

OBJECTIVE

The Acquired Preparedness (AP) model proposes that impulsive personality traits predispose some individuals to learn certain behavior-outcome associations (expectancies), and that these expectancies in turn influence the escalation of risky behaviors. This theory has been applied to the development of behaviors such as drinking, drug use, gambling, and disordered eating. In the current study, we aimed to summarize empirical tests of this model over the 20 years since it was proposed.

METHOD

We used a descriptive approach to summarize tests of mediation across 50 studies involving n=21,715 total participants.

RESULTS

We observed a consistent effect of personality on expectancies (median effect size = .22), of expectancies on behavior (.24), and a small mediated effect (.05) of personality on behavior via expectancies. Impulsive traits that involve positive or negative affect showed the most consistent support for AP, as did positive expectancies. Most studies testing AP focused on alcohol, but research on other behaviors also showed support for AP.

CONCLUSIONS

The literature appears to support a small mediated effect consistent with the AP model. Future research should continue to clarify which AP pathways are most influential in explaining risky behaviors, and supplement correlational research with experimental and quasi-experimental designs.

Parsing the link between reinforcement sensitivity theory and eating behavior: A systematic review

The Reinforcement Sensitivity Theory (RST) is a widely studied psychobiological model of personality. RST factors seem to influence eating behavior, but how these personality traits are associated with distinct features of eating behavior is still unclear. In the present systematic review, we analyzed the relationship between RST personality factors and eating behavior using a parsing approach in which BMI-related results, self-reported results, and behavioral results were distinguished. Our analysis revealed that reward and punishment sensitivity seem to correlate and influence distinct features of eating behavior. The association between BMI and RST factors was uncertain, but nonlinear associations between reward sensitivity and weight need further testing. Reward sensitivity was linked to most eating behavior phenotypes (e.g., emotional eating and restrained eating), but only punishment sensitivity was primarily correlated with eating pathology. Reward sensitivity was the main factor linked with reactivity to food stimuli on many behavioral measures. The neurobiological personality factors of RST offer parsimonious concepts to understand eating behavior outcomes and the differential relationships observed are useful to translational research.

Emotion dysregulation moderates the relationship between alcohol use and eating pathology among heavy-drinking college men

OBJECTIVES

There is limited research examining the relationship between alcohol use and eating pathology in men or factors that may moderate this association. The current study investigated the relationship between alcohol use and eating pathology, and examined emotion dysregulation as a moderator of this association, among heavy-drinking college men.

METHOD

Men mandated to receive an alcohol intervention (N = 88; average age = 19 years) completed questionnaires related to alcohol use, emotion dysregulation, and eating pathology.

RESULTS

Results demonstrated positive relationships between alcohol use and some eating pathology, and a significant interaction between alcohol use and emotion dysregulation. However, results were contrary to hypotheses, such that there was a positive relationship between alcohol use and eating pathology at low levels of emotion dysregulation.

CONCLUSION

Future studies should continue to examine the overall presentation of eating pathology in men and investigate factors that may impact the relationship between alcohol use and eating pathology.

Reliability and validity of a short Japanese version of the UPPS-P Impulsive Behavior Scale

•

A Japanese version of the S-UPPS-P Impulsive Behavior Scale is needed.

•

The original five-factor model had the best conformity index in all models.

•

The five scales’ α coefficient and the test-retest reliability were high.

•

The convergent validity of the five scales with personality scales was supported.

Objective

This study aimed to verify the reliability and validity of a Japanese version of the S-UPPS-P Impulsive Behavior Scale. This is expected to facilitate comparisons of findings between international and Japanese samples in studies of impulsivity.

Methods

Two surveys were conducted. In the first survey, 632 participants, aged 20–44 years old, completed a translated version of the Japanese S-UPPS-P Impulsive Behavior Scale, the Motor Impulsiveness Scale, a short form of the Big-Five scale, the short Grit scale, and the brief version of the self-control scale. Two weeks later, the second survey containing the S-UPPS-P and the motor impulsiveness scale were completed by 450 participants who had completed the first survey to examine test-retest reliability.

Results

In the first survey, an exploratory factor analysis was performed on the S-UPPS-P responses. A four-factor solution was the most suitable solution, with the factors of “Lack of Perseverance,” “Lack of Premeditation,” “Sensation Seeking,” and “Negative-Positive Urgency.” Then, a confirmatory factor analysis was performed. The conformity index of the original five-factor model was slightly better than that of the four-factor model. We also compared the five-factor model’s conformity index with three other models that had been examined in the original and other foreign language versions of the S-UPPS-P. The five-interrelated factor model had the best model fit. The reliability of the five scales was confirmed. The scales exhibited internal consistency with α coefficients ranging from 0.65 to 0.79, in addition to the test-retest reliability ranging from 0.74 to 0.80. The convergent validity of each S-UPPS-P scale was supported by high relationships with the four personality scales, with the highest correlation coefficients ranging from 0.37 to −0.67.

Conclusion

The reliability and validity of the Japanese version of the S-UPPS-P were confirmed, despite the minor limitations of the exploratory factor analysis providing a four-factor solution instead of a five-factor solution, and the α reliability coefficients of two scales being acceptable but rather low. Thus, comparisons of findings between international and Japanese studies on impulsivity could be facilitated.
