Examining compulsive exercise as a risk factor for eating disorder symptoms in first-year college students using a latent change score modeling approach.

OBJECTIVE: Research suggests that both compulsive exercise and eating disordered behaviors increase during college. Despite strong cross-sectional associations between compulsive exercise and eating disorders, it is unknown if compulsive exercise is a variable risk factor for eating disorders or simply a correlate. It was hypothesized that increases in compulsive exercise would significantly and prospectively predict increases in overall number of eating disorder symptoms over the study period. METHOD: A total of 265 first year college students who did not meet criteria for a full or subthreshold eating disorder diagnosis at Time 1 (age M = 18.15; SD = 0.42; 122 female [46%] at Time 1) completed reports of compulsive exercise and eating disorder symptoms via online questionnaires at four timepoints over the 9-month 2021-2022 academic year (76% retention rate). Hypotheses were tested using a bivariate latent change score model. RESULTS: Hypotheses were not supported. Change in compulsive exercise did not predict change in number of eating disorder symptoms. Change in number of eating disorder symptoms also did not predict change in compulsive exercise. CONCLUSIONS: Compulsive exercise did not emerge as a variable risk factor for the development of eating disorder symptoms among first year college students. The relationship between these behaviors should be investigated at different developmental timepoints, such as early adolescence, and potential third variables that may explain the observed co-occurrence should be explored. PUBLIC SIGNIFICANCE: This study investigated whether increases in compulsive exercise predicted increases in number of eating disorder symptoms among first year college students. Compulsive exercise did not significantly predict number of eating disorder symptoms. Additional research is warranted to clarify the relationship between compulsive exercise and eating disorder symptoms.

Visceral sensitivity, hunger responsiveness, and satiety responsiveness: Associations between facets of gastrointestinal interoception and disordered eating profiles in an undergraduate sample.

This preregistered study examined associations between empirically derived profiles of disordered eating in a diverse nonclinical sample and three facets of gastrointestinal (GI) interoception (visceral sensitivity, hunger responsiveness, satiety responsiveness). University students (n = 591; 53.3% women; 23.0% Hispanic) completed the Visceral Sensitivity Index, Adult Eating Behavior Questionnaire, and Eating Pathology Symptom Inventory. Latent profile analysis was conducted in Mplus v8.3 with four behavioral indicators (restricting, binge eating, excessive exercise, purging [binary]). Facets of GI interoception predicting odds of disordered eating profile membership compared to an asymptomatic group were evaluated. Five profiles were identified. Facets of GI interoception differentially predicted odds of membership in disordered eating profiles. However, higher scores on all three facets of GI interoception were associated with increased odds of membership in a high disordered eating profile. The relationship between distinct facets of GI interoception and specific disordered eating patterns appears nuanced, though individuals displaying a range of disordered eating behaviors may exhibit broad GI interoceptive dysfunction. Findings are consistent with the recent emphasis on idiographic treatment approaches for disordered eating and may have implications for screening among university students. Prospective longitudinal work and extension to clinical samples is needed.

Food approach and avoidance craving: A partial test of the Ambivalence Model of Craving.

Accumulating evidence from both cross-sectional and cue-reactivity studies supports the application of the Ambivalence Model of Craving (AMC) from the substance use literature to food craving. The focus of this extant work has been on the association between the two dimensions of food craving (approach and avoidance) and disordered eating behaviors. The present study extended existing validity data by investigating approach and avoidance food craving profiles and their associations with 1) disordered eating behaviors and 2) thinness/restriction and eating expectancies - a risk factor for disordered eating that is explicitly described by the AMC. It was anticipated that food craving profiles would parallel those defined by the AMC (i.e., approach oriented, avoidance oriented, ambivalent, indifferent) and that profiles defined by high avoidance food craving would be higher in compensatory behaviors, restricting behaviors, and thinness/restriction expectancies, while those defined by high approach food craving would be higher in binge eating and eating expectancies. A sample of 407 undergraduate students (54% female, 47% non-Hispanic White; Mage = 21 years) reported demographics, food craving disordered eating behaviors, and thinness/restriction and eating expectancies via an anonymous online survey. Latent profile analysis was used to test hypotheses. Hypotheses were partially supported. Four profiles were identified, but similar levels of approach and avoidance food craving were observed in each profile, with the intensity of the cravings increasing across the four profiles. Endorsement of disordered eating behaviors and expectancies also increased in intensity across the profiles. Findings suggest an additive, rather than interactive, effect of food craving.

Comparing Group Versus Individual Prenatal Care on Breastfeeding Practice and Motivational Factors.

OBJECTIVE: Although breastfeeding in the first 6 months postpartum benefits both infants and mothers, breastfeeding rates remain low. This study examined whether group prenatal care was associated with an increased breastfeeding initiation and duration compared with those receiving usual, individual prenatal care. A secondary aim was to investigate whether sociodemographic and motivational factors were associated with breastfeeding initiation and duration across prenatal care groups. METHODS: Pregnant women in their third trimester (n = 211) from an innercity university medical center participated. Prenatal care type was identified from the medical chart, and data on breastfeeding duration at 1, 3, and 6 months postpartum were collected. Breastfeeding motivational factors were assessed with a survey. Logistic regressions and independent-samples t tests were used for data analyses. RESULTS: After controlling for demographic factors, group prenatal care was associated with increased breastfeeding at 6 months postpartum (odds ratio = 2.66; P = .045) compared with individual care. Breastfeeding intention (P < .001), competence (P = .003), and autonomous motivation (P < .001) were significantly higher, while amotivation (P = .034) was significantly lower in group compared with individual prenatal care. CONCLUSIONS: Breastfeeding persistence was higher among women receiving group prenatal care, potentially due to motivational factors. Future studies should investigate how breastfeeding motivational factors could be effectively targeted in prenatal care to increase breastfeeding persistence.

Adolescent Females' Dyadic Conversations About Body, Weight, and Appearance.

Body talk among adolescent females has been associated with negative outcomes, including depressed mood, disordered eating, and body dissatisfaction. Yet, little work has investigated the manifestation of body talk in actual conversations between adolescent females or explored pathways through which body talk is spread (e.g., co-rumination). The present study examined body talk among adolescent female dyads (N = 23 dyads) ages 13 to 17 (Mage = 15.12) using an observational design. Reciprocally nominated dyads were recruited from a high school in the southeastern United States. Conversations between dyads were qualitatively coded using an applied thematic analysis approach. Identified themes were related to weight, appearance, and personality. Results provide insight into the social context in which sociocultural norms of weight stigma, body dissatisfaction, and eating-related psychopathology may be reinforced. Findings have implications for informing the development of interventions to reduce co-rumination of negative weight- and appearance-related body talk and to promote positive body image and healthy weight among adolescent girls.

Women's disordered eating and sexual function: the role of interoception.

BACKGROUND: Among women, disordered eating and sexual difficulties commonly co-occur. AIM: We investigated whether interoceptive dysfunction (ie, altered processing of body cues) may be a common cause (ie, third variable) contributing to these concomitant outcomes above and beyond body mass index (BMI) and body image concerns. METHODS: Women (n = 1201; mean age = 25.92 years; mean BMI = 25.46 kg/m2; 61.6% heterosexual, 27.5% bisexual) were recruited from sexual education courses at a midsize southeastern university and Reddit communities related to women's health, sex, and disordered eating. Participants completed online measures of self-reported interoception (Multidimensional Assessment of Interoceptive Awareness Version 2), disordered eating attitudes and behaviors (Eating Disorder Examination Questionnaire), sexual function (Female Sexual Function Index), and demographic information, including height and weight. Regression, commonality, and dominance analyses were completed in R. OUTCOMES: Sexual function was assessed via the Female Sexual Function Index. RESULTS: Both general interoception and body trust (a facet of interoception concerned with trust of internal sensations) predicted dietary restraint and sexual function (Ps < .001). After accounting for both general interoception (ß = 0.27, P < .001) and body trust (ß = 0.32, P < .001) in hierarchal regression models predicting sexual function, dietary restraint either evidenced a reduction in its standardized beta or was no longer associated with sexual function. Body image concerns also emerged as a robust predictor of women's sexual function. Body trust accounted for the most unique variance (4.45%) in women's sexual function and commonly accounted for another 3.70% of variance with body image concerns. CLINICAL IMPLICATIONS: Interoceptive exposure interventions may contribute to better outcomes for women with disordered eating, sexual difficulties, or co-occurring concerns, a notion worthy of future investigation. STRENGTHS AND LIMITATIONS: Strengths include a large diverse sample in terms of sexual orientation (>35% sexual minority) and body size (BMIs from underweight to class 3 obesity). The cross-sectional nature of this study precludes any conclusions regarding temporal precedence or causality. Future studies should use different measures of dietary restraint for nonclinical populations (eg, objective measures of caloric intake). CONCLUSION: Findings suggest that both interoception and body image concerns contribute to the co-occurrence of disordered eating behaviors and sexual difficulties, and that both may be important risk/maintaining factors to consider in future work. Interoception should be integrated into models of women's sexual function, as it may be just as important to women's sexual well-being as body image concerns.

Delivering ADAPT+ to Latino Families Living in Rural Communities: Feasibility and Acceptability of Implementing a Health Promotion Program Including Mindfulness.

BACKGROUND: Obesity is a major public health crisis in Latino youth. Mounting evidence implicates stress in the development and maintenance of obesity. This study examined the feasibility and acceptability of having community health workers, i.e., promotoras, deliver Adaptando Dieta y Acción Para Todos (ADAPT)+, a family-based health promotion program integrating mindfulness strategies for stress reduction to underserved Latino families in rural communities. METHODS: In an ORBIT model Phase IIb longitudinal quasi-cluster feasibility study, promotoras delivered the 6-session ADAPT+ intervention and 1-session Enhanced Usual Care (EUC) in rural Florida. Feasibility was assessed via sample size and recruitment, randomization by community, data collection completion, and intervention fidelity. Acceptability was assessed via participant retention and program satisfaction. Effect sizes of differences in parent stress and mindful eating between conditions at baseline, end of treatment, and 3-month follow-up were calculated. RESULTS: Feasibility and acceptability were demonstrated. The recruitment target was 99% met (n = 95 recruited). Randomization was limited to site level due to coronavirus disease 2019-related challenges. Data collection procedures were feasible (100% completion). Retention was 86% at post-assessment and 82.6% at 3-month follow-up. All sessions were completed (100% fidelity). Mean program satisfaction was 3.91/4.00. ADAPT+ parents reported lower stress (difference = -3.04, medium-to-large effect, d = .70) and more mindful eating (difference = 2.00, medium effect, d = .44) than EUC parents at 3-month follow-up. CONCLUSION: Study implementation and intervention delivery to rural Latino families using promotoras were feasible and acceptable. Promising findings regarding parent stress and mindful eating support a larger (ORBIT Phase III) efficacy trial. CLINICAL TRIAL REGISTRATION: This trial was registered with ClinicalTrials.gov under identifier NCT04800432.

Examination of the two-step water load test as a measure of gastric interoception and associations with eating and weight/shape concerns in a nonclinical sample.

OBJECTIVE: The current study extended research examining the validity of the two-step Water Load Test (WLT-II), an objective, laboratory-based measure of gastric interoception, by investigating the validity of the WLT-II in a nonclinical sample and testing its contribution to the prediction of eating and weight/shape concerns. METHODS: Participants (n = 129, 73.6% cisgender female, M = 20.13 years old) completed the WLT-II Questionnaire and two-step WLT-II, as well as self-report measures of eating and weight/shape concerns (Eating Disorder Examination Questionnaire; EDE-Q) and interoception (Multidimensional Assessment of Interoceptive Awareness-2; Intuitive Eating Scale-2 Reliance on Hunger and Satiety), in the lab at a large southeastern university. Data analysis included repeated measures ANOVA, correlations, and a series of hierarchical linear regressions. RESULTS: Participants reported considerably more discomfort after the "maximum fullness" trial compared to the "satiation" trial. The WLT-II's objective measure of gastric interoception (sat_%) was not significantly correlated with the self-report measures of interoception and did not predict EDE-Q Dietary Restraint, Eating Shame, or Weight/Shape Concerns. Unexpectedly, greater gastric sensitivity was associated with less EDE-Q Preoccupation/Restriction. Exploratory analyses suggested a possible nonlinear association. DISCUSSION: These results support the validity of the WLT-II in its ability to create, measure, and distinguish between the states of satiation and maximum fullness. However, results also suggest additional work is needed to better understand what the WLT-II's sat_% measure is capturing, as well as investigate potential nonlinear associations of the WLT-II with disordered eating. PUBLIC SIGNIFICANCE: Interoception, or the processing of internal body signals, shows important links to disordered eating. Despite the clear relevance of gastric interoception to disordered eating-such as the ability to detect satiety signals-existing research has relied on general, self-report measures of interoception. This study examined the utility of a laboratory-based measure of gastric interoception. Results suggested mixed support for its validity and utility for predicting eating and weight/shape concerns in a nonclinical population.

Latin American Trans-ancestry INitiative for OCD genomics (LATINO): Study protocol.

Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder. Worldwide, its prevalence is ~2% and its etiology is mostly unknown. Identifying biological factors contributing to OCD will elucidate underlying mechanisms and might contribute to improved treatment outcomes. Genomic studies of OCD are beginning to reveal long-sought risk loci, but >95% of the cases currently in analysis are of homogenous European ancestry. If not addressed, this Eurocentric bias will result in OCD genomic findings being more accurate for individuals of European ancestry than other ancestries, thereby contributing to health disparities in potential future applications of genomics. In this study protocol paper, we describe the Latin American Trans-ancestry INitiative for OCD genomics (LATINO, https://www.latinostudy.org). LATINO is a new network of investigators from across Latin America, the United States, and Canada who have begun to collect DNA and clinical data from 5000 richly phenotyped OCD cases of Latin American ancestry in a culturally sensitive and ethical manner. In this project, we will utilize trans-ancestry genomic analyses to accelerate the identification of OCD risk loci, fine-map putative causal variants, and improve the performance of polygenic risk scores in diverse populations. We will also capitalize on rich clinical data to examine the genetics of treatment response, biologically plausible OCD subtypes, and symptom dimensions. Additionally, LATINO will help elucidate the diversity of the clinical presentations of OCD across cultures through various trainings developed and offered in collaboration with Latin American investigators. We believe this study will advance the important goal of global mental health discovery and equity.

Boredom proneness, interoception, and emotional eating.

Emotional eating is associated with weight gain and difficulty losing weight during weight loss interventions. Theoretical and empirical work suggest boredom may be an important predictor of problematic eating behaviors. Yet, little work has examined the role of boredom in emotional eating. Further, individual differences in the ability to recognize internal cues (i.e., interoception) may alter the impact of boredom on emotional eating. This study hypothesized that boredom proneness would predict unique variance in emotional eating after accounting for negative and positive affect, and that the association between boredom proneness and emotional eating would be stronger among those with poorer interoceptive ability compared to those with better interoceptive ability. Hypotheses were tested in two large samples using multiple linear regression. Participants aged 18-65 were recruited from MTurk (n = 365; 59.2% female) and an undergraduate research pool (n = 461; 52.9% female). Participants completed self-report measures: Boredom Proneness Scale; Dutch Eating Behavior Questionnaire- Emotional Eating; Multidimensional Assessment of Interoceptive Awareness-2; Intuitive Eating Scale-2- Reliance on Hunger and Satiety Cues; and Positive and Negative Affect Schedule. Boredom proneness was a significant predictor of emotional eating in both samples, even accounting for the broad dimensions of negative and positive affect (ps < .001). Interoception did not moderate the association between boredom proneness and emotional eating in either sample (ps > .05), but was an independent predictor of emotional eating (ps < .001). Boredom proneness and interoceptive ability may warrant attention as targets in the prevention and treatment of emotional eating. Future work should continue exploring different emotion categories and different facets of interoception in emotional eating, as well as examine novel mechanisms that could inform intervention efforts.

General versus hunger/satiety-specific interoceptive sensibility in predicting disordered eating.

Dysfunctional interoceptive processing of hunger and satiety cues is particularly relevant to disordered eating behaviors. However, researchers often rely on general measures of interoceptive sensibility (IS1; self-reported experience of internal bodily cues) which conflate interoceptive processes across biological systems (e.g., gastric, cardiac) when assessing the role of interoception in disordered eating. Participants (N = 213; 50% female, age M = 20.77 years) were recruited from a large southeastern university for this online study and completed the Intuitive Eating Scale-2 (hunger/satiety-specific), the Multidimensional Assessment of Interoceptive Awareness-2 (general), and the Eating Disorder Inventory Interoceptive Awareness Subscale (general) as measures of IS. The Eating Pathology Symptoms Inventory was used to assess disordered eating attitudes and behaviors. Controlling for sex and body mass index, hunger/satiety-specific IS was associated with binge eating, purging, and cognitive restraint over and above general IS measures and emerged as the dominant predictor of each. Hunger/satiety-specific IS did not predict restricting behavior. Dysfunctional processing of hunger and satiety cues may be a particularly important risk factor to target in screenings and interventions for disordered eating. Findings highlight the importance of careful selection of IS measures in research and targeting hunger/satiety-specific IS in clinical interventions for disordered eating.

The transdiagnostic role of food craving: An application of substance use models.

Food craving is a transdiagnostic process underlying clinically significant disordered eating behaviors and eating disorder diagnoses. However, the lack of literature examining the role of food craving as it relates to the full spectrum of disordered eating behaviors, including restrictive eating and compensatory behaviors, may be due to the traditional definition of food craving as the desire to consume particular foods. Applying motivational models of substance use craving to food craving may help to explain inconsistencies within existing literature. Three motivational models of craving from the substance use literature may be particularly applicable to (1) provide a clear definition of food craving as a motivational process, (2) understand the role of that motivational process as it underlies the full spectrum of disordered eating behavioral patterns, (3) provide insight for the most appropriate ways in which to accurately assess food craving, and (4) establish ways in which food craving may represent a useful motivational process to target in eating disorder treatments. This narrative review describes three models of substance use craving and provides suggestions for utilizing motivational models to understand the transdiagnostic role of food craving as it relates to the full spectrum of disordered eating behaviors in both research and clinical work.

Investigating engagement in maladaptive and adaptive exercise behaviors before and during COVID-19.

PURPOSE: Evidence suggests that the coronavirus (COVID-19) pandemic has resulted in increased mental health concerns (e.g., anxiety) and there is ample discussion of how the pandemic has resulted in increases in weight control strategies (e.g., maladaptive exercise behaviors). It remains unclear, however, if maladaptive exercise behaviors are on the rise among non-clinical samples. The objective of this study was to examine college students' engagement in exercise behaviors (both adaptive and maladaptive) before and during COVID-19. METHOD: This study compared reports of compulsive exercise, weight and shape exercise, and positive and healthy exercise in two separate samples recruited from a large southeastern university. Sample 1 was collected pre-COVID-19 (August 2019-February 2020) and Sample 2 was collected during COVID-19 (August 2020-April 2021). Case-control matched samples were generated for this study (N = 144; 52.1% male). Three separate analysis of covariance models tested the differences between (1) adaptive exercise; (2) compulsive exercise; and (3) weight and shape exercise in pre- and during COVID-19 samples, controlling for sex. RESULTS: Individuals in the during COVID-19 sample reported significantly more compulsive exercise (p < .001), weight and shape exercise (p < .001), and adaptive exercise (p < .001) compared to individuals in the pre-COVID-19 sample. Effects were of medium to large sizes. CONCLUSION: Consistent with reports from the research literature and popular press, the current study observed that both adaptive and maladaptive exercise were higher among college students during COVID-19 compared to pre-COVID-19. LEVEL OF EVIDENCE: Level V: Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Intrinsic and extrinsic motivations as moderators of the association between exercise frequency and exercise behavior.

PURPOSE: Motivations underlying exercise may contribute to the extent to which exercise is maladaptive, independent of exercise frequency. Extrinsic and intrinsic exercise motivation may independently moderate associations between exercise frequency and 1) compulsive and 2) healthy exercise. It was expected that among individuals with high extrinsic motivation, greater exercise frequency would be associated with more compulsive exercise, whereas among individuals with high intrinsic motivation, greater exercise frequency would be associated with more healthy exercise. METHODS: A total of 446 university students (50.9% female; 67.0% White) completed measures of intrinsic and extrinsic exercise motivations, exercise frequency, compulsive exercise, and healthy exercise. Intrinsic and extrinsic motivations for exercise were entered as simultaneous independent moderators of the associations between exercise frequency and 1) compulsive exercise and 2) healthy exercise in multiple linear regressions. RESULTS: Moderation effects of exercise motivation were not supported for compulsive exercise. Only main effects of frequency (b = 0.04, p < 0.01) and extrinsic motivation (b = 0.27, p < 0.01) were observed. Intrinsic motivation moderated the association between frequency and healthy exercise (b = -0.02, p = 0.03). Among individuals with lower intrinsic motivation, greater frequency was related to more healthy exercise. This association was significantly weaker among individuals with high intrinsic motivation. CONCLUSION: Consistent with theory and extant work, extrinsic motivation was associated with compulsive exercise, while intrinsic motivation was associated with healthy exercise. Clinically, assessing the extent to which exercise is intrinsically or extrinsically motivated may help identify whether individuals may be more likely to engage in compulsive versus healthy exercise. Results support the importance of exploring the exercise motivations as predictors of compulsive and healthy exercise. LEVEL OF EVIDENCE: Level V, Descriptive Cross-Sectional Study.

Understanding athletic and exercise identity in relation to disordered eating behaviors.

PURPOSE: This study investigated the associations between athletic and exercise identities and a range of disordered eating and exercise behaviors. METHOD: Study 1 (N = 441; 53.5% female) included online questionnaires of athletic identity and disordered eating behaviors, anthropometrics, and demographic information. Study 2 (N = 225; 50.2% female) added measures of: exercise identity, exercise behaviors, and a broader measure of disordered eating behaviors. Multiple linear regressions were used to test hypotheses. Dominance analysis was used in Study 2 to determine the unique variance accounted for by each predictor. RESULTS: Controlling for body mass index (BMI), age, and sex, athletic identity was not significantly associated with disordered eating in Study 1 (ps > 0.039) but was significantly associated with lower cognitive restraint in Study 2 (p = 0.012). In Study 2, stronger exercise identity was significantly associated with more cognitive restraint (p < 0.001), more body dissatisfaction (p = 0.016), more compulsive exercise (p < 0.001), and more positive and healthy exercise (p < 0.001), after controlling for BMI, age, sex, and athletic identity. Dominance analyses suggested that exercise identity was more strongly associated with these outcomes than athletic identity. CONCLUSION: Exercise identity, but not athletic identity, may be an important risk factor for disordered eating and exercise behaviors in broad populations. LEVEL OF EVIDENCE: Level IV, results from uncontrolled trial.

Disentangling the Relationship between Food Insecurity and Poor Sleep Health.

The COVID-19 pandemic has created disruptions in global and national food supply chains. Along with an increase in the unemployment rate, this resulted in a rise in food insecurity at the community-level, threatening individual and family well-being. Food insecurity is associated with inadequate nutrient intakes, weight gain, and psychological distress, including anxiety and depressive symptoms, all of which are known to affect sleep. Yet, little is known about whether and how food insecurity is associated with sleep health, a critical but underrecognized health outcome. This paper reviews literature describing associations between food insecurity and sleep, summarizes key findings based on proposed mechanisms, and discusses directions for future research.

An Examination of Sex Differences in a Disease-Specific Model of Disordered Eating Behaviors in Type 1 Diabetes.

OBJECTIVE: Preliminary evidence supports the integration of type 1 diabetes (T1D) disease-specific factors into eating disorder risk models. The current study explored whether cross-sectional associations among constructs included in the modified dual pathway model of eating disorder risk for individuals with T1D are similar across sex among adolescents and young adults with T1D. METHODS: Original study participants were recruited from the T1D Exchange Clinic Network, a U.S. registry of individuals with T1D. Online surveys included measures of general eating disorder risk factors, hypothesized T1D-specific risk factors, and a T1D-specific eating disorder questionnaire. The current study is a secondary analysis with the adolescents (13-17 years; n = 307; 46.9% female) and young adults (18-25 years; n = 313; 62.6% female) from the original sample. In the absence of strong measurement invariance for all measures of interest, sex-specific path models were estimated among the adolescent and young adult cohorts. RESULTS: Only two paths emerged as significant in the female, but not male, adolescent model. In the young adult cohort, all significant paths were the same across sex. CONCLUSIONS: Both general and T1D-specific risk factors are associated with disordered eating behaviors in the T1D population. Patterns of associations were similar across male and female youth with T1D, suggesting that sex-specific prevention approaches to disordered eating behaviors among T1D youth may not be warranted.

Support for a two-dimensional model of food craving using self-report questionnaire and cue-reactivity methodologies.

OBJECTIVE: Evidence supports the transdiagnostic importance of food cravings across the spectrum of disordered eating behaviors. The ambivalence model of craving (AMC), originally applied to substance use craving, highlights the need to consider not just the motivational state of "approach," but also that of "avoidance." The aims of this project were to (a) extend the existing literature by providing additional psychometric support for the food approach and avoidance questionnaire (FAAQ), (b) extend research supporting the validity of applying the AMC to disordered eating by incorporating a cue-reactivity paradigm, and (c) examine the unique contributions of the FAAQ and in-the-moment cue-elicited craving to the prediction of disordered eating. METHOD: Participants (N = 223; 52.0% female, age M = 20.51 years) were recruited from a large southeastern university. Participants completed a food cue-reactivity paradigm and measures of food craving and disordered eating in a lab setting. RESULTS: The factor structure and construct validity of the FAAQ was supported and both general states of food craving (i.e., FAAQ) and cue-elicited food craving were incrementally associated with the spectrum of disordered eating behaviors. As anticipated, both FAAQ and in-the-moment cue-elicited approach were primarily associated with overeating behaviors, whereas FAAQ and cue-elicited avoidance were primarily associated with restrictive eating behaviors. DISCUSSION: Findings highlight the importance of including an avoidance dimension of food craving and have important implications for disordered eating prevention and intervention work.

Drive for leanness: potentially less maladaptive compared to drives for thinness and muscularity.

PURPOSE: Drive for leanness (DL), a motivating interest in having low body fat and toned muscles, is hypothesized to be less maladaptive than drives for thinness (DT) and muscularity (DM), which has implications for its inclusion in eating- and health-related prevention and treatment programs; however, little research has explored this hypothesis. The current study investigated DL's uniqueness from these other drives, as well as simultaneously explored if associations of DL and a range of health-related outcomes supported that it may be less maladaptive than DT and DM. METHODS: A sample of 589 undergraduate participants completed an online battery of drive (DL, DT, DM) and health-related measures (disordered eating, aerobic and weight training frequency, exercise motivation, dieting, appearance enhancing supplement use, anxiety, and depression). Exploratory factor analysis and semi-partial correlations evaluated DL's uniqueness. Hierarchical regressions and generalized linear models evaluated comparative associations of drives with health-related outcomes. Analysis of covariance investigated comparative perceived drive healthiness. RESULTS: DL was supported as unique from DT and DM. DL was less strongly associated with maladaptive outcomes (e.g., disordered eating, ExpB = .99, p = .86) and more strongly predictive of adaptive outcomes (e.g., healthy exercise motivation, ß = .30, p < .001) than DT or DM. DL was perceived as healthier than either other drive. CONCLUSIONS: DL was supported as a unique and less maladaptive motivation than DT or DM, suggesting the emergence of a lean ideal may be less problematic than body ideals focused on either thinness or muscularity alone. LEVEL OF EVIDENCE: V, cross-sectional descriptive study.

Development and Psychometric Evaluation of a Brief Approach and Avoidance of Alcohol Questionnaire.

BACKGROUND: The Approach and Avoidance of Alcohol Questionnaire (AAAQ) was developed as a measure of craving to assess both desires to consume and desires to avoid consuming alcohol. Although the measure has been used in a variety of populations to predict future alcohol use behavior, the factor structures observed vary based on sample type (e.g., clinical vs. college samples) and may be overly long for use in repeated measures designs. The current article describes the development of a brief version of the AAAQ for use in clinical populations. METHODS: Using existing data sets of individuals in treatment for alcohol use disorder, exploratory analyses (e.g., exploratory factor analysis and item response theory) were conducted using an inpatient sample (N = 298) at a substance abuse treatment facility. Confirmatory analyses (e.g., confirmatory factor analysis and multiple regression) were conducted using an inpatient detoxification sample (N = 175) and a longitudinal outpatient treatment sample (N = 53). RESULTS: The brief AAAQ had comparable internal consistency, explained a similar amount of variance in alcohol consumption and related problems, and exhibited superior model fit as compared to the original measure. CONCLUSIONS: These findings indicate that the brief AAAQ is an effective tool to assess alcohol craving in clinical populations in treatment settings.
