Examination of college student health behaviors and self-reported executive functions.

Objective: Emerging adulthood is characterized by maturation of executive functions (EF) and changes in health behaviors (HB). Interestingly, EF are bi-directionally related to many specific HB; yet how EF performs in relation to overall patterns of HB engagement is unclear. Groupings of HB and the relationship between these HB groupings and EF were examined. PARTICIPANTS: Full-time college students were recruited from three large Mid- and Southwest universities (N = 1,387). METHODS: Online self-report questionnaires assessing demographics, HB, and EF were completed. RESULTS: Latent class analysis of HB revealed three classes: (1) High Substance Use, (2) Moderately Healthy, (3) Healthy. In general, the Healthy class had significantly greater EF compared to no significant differences between the other two classes. CONCLUSIONS: Collective engagement in HB is associated with EF. Interventions targeting both HB and EF simultaneously may be most efficacious.

Furthering the Understanding of Wechsler Adult Intelligence Scale-Fourth Edition Factor Structure in a Clinical Sample.

The Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV) is a commonly administered battery for assessing intellectual and cognitive abilities. Despite its popularity, construct validation studies primarily utilize the WAIS-IV normative sample rather than ecologically-valid clinical samples. The current study expands the literature on the validity of WAIS-IV by testing a bifactor model in such a sample. We examined archival data from 300 concurrent psychological evaluations performed at a university-based community clinic. Participants received the full WAIS-IV standard battery. Consistent with recent literature, confirmatory factor analyses (CFAs) favored a direct hierarchical model, where the g factor has a direct influence on WAIS-IV subtest performance and index scores explain only modest degrees of residual variance. Results challenge traditional intelligence nosologies and suggest consideration of a two-step method of WAIS-IV interpretation in clinical samples, whereby the Full Scale IQ score (FSIQ) score is examined first and individual subtest scores are analyzed second.

The Clinical Significance of Food Addiction.

OBJECTIVES: The construct of food addiction has received increased attention and has been proposed as a mental disorder. There is some evidence that supports the inclusion of food addiction in the psychiatric nosology; however, the construct has not been sufficiently validated for inclusion. This study used the addiction syndrome model as a guiding theoretical framework to understand food addiction. The addiction syndrome model emphasizes the shared antecedents and consequences of addictions even though specific manifestations may differ. METHODS: Participants were adult community members with food addiction (n = 26) or healthy controls (n = 26) as classified by the Yale Food Addiction Scale. Participants completed a battery of self-report questionnaires assessing cognitive, emotional, and behavioral domains often associated with addiction. RESULTS: Results revealed that individuals with food addiction demonstrated significantly higher scores than healthy controls on depressive symptoms, emotion dysregulation, emotional eating, demand characteristics, motives, impulsivity, and family history of mental health problems and addiction, providing support for the clinical significance of food addiction. CONCLUSIONS: Overall, this study replicates and extends previous findings, particularly in regard to behavioral economics and demand for food, providing further support for the consideration of food addiction in the psychiatric nosology.

Examining the stability of the UPPS-P and MCQ-27 during residential treatment for substance use disorder.

Impulsivity reflects a pattern of rapid behavioral responses to internal or external cues with little planning or consideration of consequences. Impulsive personality is purported to be a largely stable, trait-based quality, while impulsive choice has been shown to respond to interventions aimed at reducing impulsivity. We sought to evaluate the stability of impulsive personality and examine reductions in impulsivity during short-term residential substance use disorder (SUD) treatment. The temporal stability of the UPPS-P Impulsive Behavior Scale (UPPS-P) and discounting rates on a measure of impulsive choice (i.e., Monetary Choice Questionnaire-27 [MCQ-27]) were assessed over a brief 10-day period in a sample of individuals engaged in 14-day residential SUD treatment (N = 28). Although all five UPPS-P scales exhibited adequate to good test-retest reliability (rs > .78), Negative Urgency and (lack of) Premeditation decreased over time with large and moderate effects, respectively. Discounting rates on the MCQ-27 also declined (i.e., reduced impulsivity) during treatment. While impulsive personality is broadly understood to be trait-like and largely resistant to treatment effects, our results add to emerging evidence that two scales on the UPPS-P (i.e., Negative Urgency and [lack of] Premeditation) measure aspects of impulsive personality that respond to treatment. These findings have significant implications for understanding and conceptualizing impulsivity during initial SUD treatment and suggest opportunities for additional interventions targeting aspects of impulsive personality.

Health Outcomes in Individuals with Problem and Pathological Gambling: An Analysis of the 2014 North Carolina Behavioral Risk Factor Survey System (BRFSS).

Problem and pathological gambling refers to subclinical and clinical levels of maladaptive gambling, respectively, and is associated with specific sociodemographic characteristics as well as a number of poor health outcomes. We examined such demographic, physical health, mental health, and health-related behaviors in a sample of 7045 low-risk gamblers and 244 problem/pathological gamblers. Participants completed the 2014 North Carolina Behavioral Risk Factor Surveillance System telephone survey. Using the National Opinion Research Center's Diagnostic Screen for Gambling Disorders-CLiP, participants were categorized as either "problem/pathological gamblers" or "low-risk gamblers." Problem/pathological gamblers were younger, more likely to be male, of ethnic minority status, unmarried, and of lower education than low-risk gamblers. No physical health variables differentiated the groups but problem/pathological gamblers reported experiencing significantly more adverse childhood experiences and engaging in significantly more tobacco and alcohol use compared to low-risk gamblers. Moreover, gender moderated relationships between gambling group and several of the alcohol use variables such that male problem/pathological gamblers exhibited greater alcohol use behavior than male low-risk gamblers but no such relationship was present in females. Overall, this study expands the current knowledgebase on disordered gambling and highlights the need to assess disordered gambling in public health samples. Clinical implications are discussed.
