Identifying overcontrol and undercontrol personality types among young people using the five factor model, and the relationship with disordered eating behaviour, anxiety and depression. J Eat Disord 2024; 12:16. [PMID: 38267972 PMCID: PMC10809654 DOI: 10.1186/s40337-024-00967-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 01/07/2024] [Indexed: 01/26/2024] Open
Abstract
BACKGROUND Overcontrol and undercontrol personality types have been associated with an increase in eating pathology, depression and anxiety. The aim of the research was to explore whether latent overcontrol and undercontrol personality types could be identified using cluster analysis of the facets of the five factor model (FFM). We further aimed to understand how these personality types were associated with eating pathology, depressed mood and anxiety. METHODS A total of 561 participants (394 women and 167 men), aged 16-30 years in Australia completed a survey designed to assess disordered eating, FFM personality traits, anxiety, depression and stress. A systematic four-step process using hierarchical, k-means, and random forest cluster analyses were used to identify a meaningful 3-cluster solution. RESULTS The results revealed a cluster solution that represented overcontrol, undercontrol and resilient personality types, and highlighted facets of the FFM that were associated with each type. Both overcontrol and undercontrol personality types were associated with increased clinical symptoms compared to the resilient types. CONCLUSIONS It was concluded that FFM facets may potentially be more meaningful than broad domains in identifying personality types, and that both overcontrol and undercontrol personality types are likely associated with increased clinical symptoms.

Examining the secondary impacts of the COVID-19 pandemic on syndemic production and PrEP use among gay, bisexual and other men who have sex with men (GBM) in Vancouver, Canada. BMC Public Health 2023; 23:2124.

Abstract
BACKGROUND The secondary impacts of the COVID-19 pandemic may disproportionately affect gay, bisexual, and other men who have sex with men (GBM), particularly related to HIV prevention and treatment outcomes. We applied syndemic theory to examine PrEP disruptions during the during the height of the COVID-19 pandemic in Vancouver, Canada. METHODS Sexually-active GBM, aged 16 + years, were enrolled through respondent-driven sampling (RDS) from February 2017 to August 2019. Participants completed a Computer-Assisted Self-Interview every six months and data were linked to the BC PrEP Program (program responsible for publicly funded PrEP in the province) to directly measure PrEP disruptions. The analysis period for this study was from March 2018-April 2021. We used univariable generalized linear mixed models to examine (1) six-month trends for syndemic conditions: the prevalence of moderate/severe depressive or anxiety symptoms, polysubstance use, harmful alcohol consumption, intimate partner violence, and (2) six-month trends for PrEP interruptions among HIV-negative/unknown GBM. We also applied 3-level mixed-effects logistic regression with RDS clustering to examine whether syndemic factors were associated with PrEP interruptions. RESULTS Our study included 766 participants, with 593 participants who had at least one follow-up visit. The proportion of respondents with abnormal depressive symptoms increased over the study period (OR = 1.35; 95%CI = 1.17, 1.56), but we found decreased prevalence for polysubstance use (OR = 0.89; 95%CI = 0.82, 0.97) and binge drinking (OR = 0.74; 95%CI = 0.67, 0.81). We also found an increase in PrEP interruptions (OR = 2.33; 95%CI = 1.85, 2.94). GBM with moderate/severe depressive symptoms had higher odds (aOR = 4.80; 95%CI = 1.43, 16.16) of PrEP interruptions, while GBM with experiences of IPV had lower odds (aOR = 0.38; 95%CI = 0.15, 0.95) of PrEP interruptions. GBM who met clinical eligibility for PrEP had lower odds of experiencing PrEP interruptions (aOR = 0.25; 95%CI = 0.11, 0.60). CONCLUSION There were increasing PrEP interruptions since March 2020. However, those most at risk for HIV were less likely to have interruptions. Additional mental health services and targeted follow-up for PrEP continuation may help to mitigate the impacts of the COVID-19 pandemic on GBM.

Abstract
Introduction The Personality Inventory for DSM-5 (PID-5) is a self-report measure of personality pathology designed to measure pathological personality traits outlined in the DSM-5 alternative model of personality disorders. Within the extensive literature exploring the relationship between personality and disordered eating, there are few that explore the relationship between the PID-5 and disordered eating behaviours in a non-clinical sample of males and females: restrictive eating, binge eating, purging, chewing and spitting, excessive exercising and muscle building. Methods An online survey assessed disordered eating, PID-5 traits and general psychopathology and was completed by 394 female and 167 male participants aged 16-30. Simultaneous equations path models were systematically generated for each disordered eating behaviour to identify how the PID-5 scales, body dissatisfaction and age predicted behaviour. Results The results indicated that each of the six disordered behaviours were associated with a unique pattern of maladaptive personality traits. The statistical models differed between males and females indicating possible differences in how dimensional personality pathology and disordered eating relate. Discussion It was concluded that understanding disordered eating behaviour in the context of personality pathology may assist formulating potentially risky behaviour.

Abstract
There is a wealth of research that has highlighted the relationship between personality and eating disorders. It has been suggested that understanding how subclinical disordered eating behaviours are uniquely associated with personality can help to improve the conceptualization of individuals with eating disorders. This study aimed to explore how the facets of the Five-Factor Model (FFM) predicted restrictive eating, binge eating, purging, chewing and spitting, excessive exercising and muscle building among males and females. An online survey assessing disordered eating behaviours, FFM and general psychopathology was completed by 394 females and 167 males aged between 16 and 30 years. Simultaneous equations path models were systematically generated for each disordered eating behaviour to identify how the FFM facets, body dissatisfaction and age predicted behaviour. The results indicated that each of the six disordered behaviours were predicted by a unique pattern of thinking, feeling and behaving. Considerable differences between males and females were found for each path model, suggesting differences between males and females in the personality traits that drive disordered eating behaviours. It was concluded that it is important to take personality into account when treating males and females who engage in disordered eating behaviours.

Association of current and remitted bipolar disorders with health-related quality of life: Findings from a nationally representative sample in the US. J Affect Disord 2023; 321:33-40.

Abstract
BACKGROUND The associations of current and remitted bipolar disorder (BD) with health-related quality of life (HRQOL) have been under-studied, and we aim to address these gaps. METHODS The 2012-2013 National Epidemiological Survey on Alcohol and Related Conditions III (NESARC III) surveyed a nationally representative sample of non-institutionalized adults in the US. Using DSM-5 criteria, three groups were operationalized as: 1) adults who met criteria for BD in the past year (i.e., current BD; n = 566 unweighted); and 2) adults who met criteria for BD previously but not in the past year (i.e., BD in remission; n = 187); and 3) adults with no BD in their lifetime (n = 35,556). HRQOL and quality-adjusted life years (QALYs) were compared by these groups. Multivariable-adjusted regression analyses were used to adjust for and examine the role of covariates. RESULTS Overall, 1.5 % of the study sample, representing 3.6 million adults nationwide, met criteria for current BD, and 0.5 %, representing 1.3 million adults, met criteria for BD in remission. Adults with current BD and BD in remission had lower mental HRQOL and QALYs, as compared to adults who never had BD. However, these differences were no longer significant when adjusted for behavioral co-morbidities (e.g., psychiatric and substance use disorders). CONCLUSION Both current BD and BD in remission were adversely associated with HRQOL and QALYs, while these associations were not independent of behavioral co-morbidities. Because behavioral co-morbidities are common in individuals with current BD or those with BD in remission, they should be treated together to improve HRQOL.

[PMID: 35124542 PMCID: PMC8805909 DOI: 10.1016/j.eatbeh.2022.101597] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 01/07/2022] [Accepted: 01/21/2022] [Indexed: 11/16/2022]
Abstract
'Feeling fat,' the somatic experience of being overweight not entirely explained by objective weight, may occur due to the projection of negative affect onto the body. Individuals may manage 'feeling fat' via eating pathology (e.g., binge eating or dietary restriction) rather than address the source of negative affect. Thus, 'feeling fat' may occur in the absence of adaptive emotion regulation strategies. The COVID-19 pandemic has increased negative affect widely and may potentially contribute to the experience of 'feeling fat' and eating pathology among individuals with emotion dysregulation. This study examined whether emotion dysregulation moderates 'feeling fat's' role as a mechanism underlying the relationship between COVID-19-related distress and eating pathology. This uniqueness of this model to eating pathology was investigated by comparing effects for binge eating and dietary restriction versus anxiety, depression, and problematic alcohol use. Structural equation modelling was used to analyze questionnaire data from 877 participants (77.3% women). 'Feeling fat' explained significant variance in the relationship between COVID-19-related distress and both binge eating and restriction. Emotion dysregulation modulated the strength of these relationships. However, 'feeling fat's role in the relationship between pandemic-related distress and negative psychological outcomes was not unique to eating pathology and did not vary based upon emotion dysregulation. Individuals with elevated emotion dysregulation are more likely to report eating pathology, but not other outcomes, in the context of 'feeling fat'. In contrast, 'feeling fat' underlies the relationship between COVID-19-distress and transdiagnostic psychological outcomes, meaning 'feeling fat' should be considered in risk for psychopathology beyond eating disorders.
