Int J Eat Disord 2023; 56:1842-1853. [PMID: 37337937 DOI: 10.1002/eat.24012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 05/07/2023] [Accepted: 06/05/2023] [Indexed: 06/21/2023]
Abstract
OBJECTIVE Previous studies have revealed associations between disordered eating symptoms, big-five personality traits, and psychological distress. However, limited research has explored these relationships as a network, including their interconnections, and even less has done so in non-Western populations. We employed network analysis to investigate the co-occurrence of disordered eating symptoms, big-five personality traits, and psychological distress in Chinese adults. METHOD A sample of 500 Chinese adults (256 men) completed measures assessing big-five personality traits, psychological distress, and disordered eating symptoms. The network of personality traits, psychological distress, and disordered eating symptoms was estimated, including its central and bridge nodes. RESULTS The central nodes in the network were the facets of openness (like adventure), extraversion (like going to social and recreational parties), and disordered eating symptoms (dissatisfaction with body weight or shape). Moreover, certain facets of neuroticism (always worrying something bad will happen), psychological distress (feeling worthless), and an inverse facet of extraversion (bored by parties with lots of people) were identified as essential bridge nodes in maintaining the structure of the network. CONCLUSION Our findings suggest that personality traits (e.g., openness and extraversion) and body dissatisfaction are important in maintaining the network in a community sample of Chinese adults. While future replication is needed, findings from this study suggest that individuals with negative self-thinking, predisposed neuroticism, and extraversion may be at risk of developing disordered eating symptoms. PUBLIC SIGNIFICANCE The present study contributes to existing knowledge by employing a network perspective to examine the associations between disordered eating symptoms, big-five personality traits, and psychological distress in a Chinese adult community sample. The identified facets of neuroticism and extraversion and symptoms of psychological distress may be worthy of targeting in the prevention and treatment of disordered eating in the Chinese context.

Appetite 2022; 179:106309. [PMID: 36115512 DOI: 10.1016/j.appet.2022.106309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 09/06/2022] [Accepted: 09/09/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVES This study aims to reveal the individual differences in Neuroticism and cognitive flexibility among successful restrained eaters (SREs), unsuccessful restrained eaters (UREs), and non-restrained eaters (NREs). Moreover, this study is dedicated to investigating whether certain personality traits and cognitive flexibility could concurrently influence disinhibited eating behaviors among restrained eaters and reveal the pathways through which they interact. METHODS Female participants aged 17 and 24 years (NREs = 23; SREs = 24; UREs = 23) were assessed with body mass index (BMI) and appetite state measurement, the Dutch Eating Behavior Questionnaire (DEBQ), the NEO Five-Factor Inventory (NEO-FFI), and the Positive and Negative Affect Schedule. To measure behavioral and neural responses related to cognitive flexibility, participants were required to complete a food-related switching task, and their brain activities were recorded through the technique of electroencephalography (EEG). Here we analyzed two widely investigated components-the N2 and P3 components that separately relate to conflict monitoring and response inhibition. RESULTS The behavioral performance of food-related task switching did not show significant between-group differences. However, in comparison to NREs and SREs, UREs elicited larger N2 and lower P3 amplitudes during task switching. In addition, UREs exhibited a lower level of Neuroticism than SREs and NREs. Furthermore, food-related task switching induced N2 amplitude fully mediated the association between Neuroticism and disinhibited eating behavior in restrained eaters controlled for BMI and negative affect. Importantly, when a parallel mediation model with N2 and P3 was built concurrently, N2 was still able to fully mediate the association. CONCLUSION According to behavioral and neural evidence, increased N2 amplitude induced by food-related task switching totally mediated the negative association between Neuroticism and disinhibited eating in restrained eaters.

Analyzing the link between anxiety and eating behavior as a potential pathway to eating-related health outcomes. Sci Rep 2021; 11:14717. [PMID: 34282257 PMCID: PMC8289991 DOI: 10.1038/s41598-021-94279-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Accepted: 07/07/2021] [Indexed: 02/02/2023] Open
Abstract
Anxiety is a widespread phenomenon that affects various behaviors. We want to analyze in how far anxiety is connected to eating behaviors since this is one potential pathway to understanding eating-related health outcomes like obesity or eating disorders. We used data from the population-based LIFE-Adult-Study (n = 5019) to analyze the connection between anxiety (GAD-7) and the three dimensions of eating behaviors (FEV)—Cognitive Restraint, Disinhibition, and Hunger—while controlling for sociodemographic variables, smoking, physical activity, personality, and social support. Multivariate regression analyses showed significant positive associations between anxiety and Disinhibition as well as Hunger, but not between anxiety and Cognitive Restraint. Interventions that help individuals to better regulate and cope with anxiety, could be one potential pathway to reducing eating disorders and obesity in the population.

Abstract
Self-rated oral health and oral health-related quality of life is known to be influenced by various personality characteristics. The aim of this study was to understand how personality characteristics affect oral health-related quality of life ratings in an Iranian adult population. The study included 443 adult participants recruited from a public dental clinic in Kerman, southeast of Iran. The Oral Health Impact Profile-14 questionnaire was used to assess oral health-related quality of life. Personality traits were determined using the 20-item Positive Affectivity Negative Affectivity Scale. Locker's single-item global self-rating of oral health was used to obtain information on self-rated oral health. Pearson correlation and negative binomial regression were used for data analysis. A higher negative affectivity score was associated with worse oral heath related quality of life, and a higher positive affectivity score was associated with better rating of oral health-related quality of life. On average, individuals who described their oral health as worse scored higher on Oral Health Impact Profile-14. Negative affectivity and positive affectivity influence individuals' perceptions of their oral health and quality of life. If possible, investigations of oral health-related quality of life measures should also include a brief personality assessment.

Personality and body dissatisfaction: An updated systematic review with meta-analysis. Body Image 2020; 33:77-89. [PMID: 32113010 DOI: 10.1016/j.bodyim.2020.02.001] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2019] [Revised: 02/02/2020] [Accepted: 02/03/2020] [Indexed: 11/24/2022]
Abstract
This research synthesis explored whether major personality dimensions relate to body dissatisfaction. A comprehensive literature search identified 26 studies (37 independent samples) that met inclusion criteria (364 effect sizes; n = 39,109). Data were analyzed using inverse-variance weighted random effects meta-analysis. Mean effect sizes from 30 individual meta-analyses provided evidence that neuroticism (r = .30), extraversion (r = -.17) and conscientiousness (r = -.16), and to a lesser extent openness (r = -.10) and agreeableness (r = -.08), relate to body dissatisfaction. Effect sizes were smaller in models that controlled for body mass index, with non-significant effects for openness and agreeableness. There was some evidence of publication bias and substantial heterogeneity in computed averages. Random effects meta-regression showed that the association between neuroticism and body dissatisfaction decreased as the sample age increased. Measurement was the most important moderator across personality dimensions, with measures of appearance evaluation and body appreciation often showing smaller associations than other measures of body dissatisfaction. Effect sizes were not moderated by sample sex or world-region. Overall, findings show that higher levels of neuroticism, and lower levels of extraversion and conscientiousness, are associated with a greater risk of body dissatisfaction in men and women irrespective of actual body weight.

Abstract
Eating disorders are among the most prevalent disorders in adolescence and can have negative consequences including poor quality of life, medical complications, and even death. This study addresses whether normal variations in personality relate to eating behavior and eating disorder symptomatology in adolescent girls. Participants were a near-representative sample of Australian adolescent girls (n = 1,676). Three personality traits (neuroticism, extraversion, and conscientiousness) were assessed at age 12 and again at age 14, and self-reported eating and weight management behaviors were assessed at age 14. After controlling for sociodemographic factors, higher levels of conscientiousness at age 12, and increases in conscientiousness between ages 12 and 14, were associated with greater fruit and vegetable consumption, a lower intake of high fat foods and high sugar drinks, less frequent meal skipping, better oral health, and decreased risk of partial syndrome bulimia nervosa at age 14. Higher neuroticism at age 12 was associated with more frequent meal skipping, and increases in neuroticism between ages 12 and 14 were associated with more frequent meal skipping and increased risk of partial syndrome bulimia nervosa at age 14. Extraversion was generally unrelated to eating and weight management behaviors. These findings provide evidence that normal variations in personality are related to eating behavior, oral health, and eating disorder symptoms during midadolescence.
