Psychology ,BF1-990 - Abstract
BackgroundThe demand for mental health (MH) services in the community continues to exceed supply. At the same time, technological developments make the use of artificial intelligence–empowered conversational agents (CAs) a real possibility to help fill this gap. ObjectiveThe objective of this review was to identify existing empathic CA design architectures within the MH care sector and to assess their technical performance in detecting and responding to user emotions in terms of classification accuracy. In addition, the approaches used to evaluate empathic CAs within the MH care sector in terms of their acceptability to users were considered. Finally, this review aimed to identify limitations and future directions for empathic CAs in MH care. MethodsA systematic literature search was conducted across 6 academic databases to identify journal articles and conference proceedings using search terms covering 3 topics: “conversational agents,” “mental health,” and “empathy.” Only studies discussing CA interventions for the MH care domain were eligible for this review, with both textual and vocal characteristics considered as possible data inputs. Quality was assessed using appropriate risk of bias and quality tools. ResultsA total of 19 articles met all inclusion criteria. Most (12/19, 63%) of these empathic CA designs in MH care were machine learning (ML) based, with 26% (5/19) hybrid engines and 11% (2/19) rule-based systems. Among the ML-based CAs, 47% (9/19) used neural networks, with transformer-based architectures being well represented (7/19, 37%). The remaining 16% (3/19) of the ML models were unspecified. Technical assessments of these CAs focused on response accuracies and their ability to recognize, predict, and classify user emotions. While single-engine CAs demonstrated good accuracy, the hybrid engines achieved higher accuracy and provided more nuanced responses. Of the 19 studies, human evaluations were conducted in 16 (84%), with only 5 (26%) focusing directly on the CA’s empathic features. All these papers used self-reports for measuring empathy, including single or multiple (scale) ratings or qualitative feedback from in-depth interviews. Only 1 (5%) paper included evaluations by both CA users and experts, adding more value to the process. ConclusionsThe integration of CA design and its evaluation is crucial to produce empathic CAs. Future studies should focus on using a clear definition of empathy and standardized scales for empathy measurement, ideally including expert assessment. In addition, the diversity in measures used for technical assessment and evaluation poses a challenge for comparing CA performances, which future research should also address. However, CAs with good technical and empathic performance are already available to users of MH care services, showing promise for new applications, such as helpline services.

Podcasts are used in educational institutions to complement learning and revision. In this paper, the incorporation of a student-created podcast component into a group assignment on vaccines was evaluated. It was hypothesised that group podcast preparation would enable health-science undergraduate students to improve their health communication and digital literacy skills. Students (n=66) were introduced to the assignment early in semester 2 of 2022, after which they attended regular coursework and training on podcasting software. Students had the opportunity to research, plan, script, curate and record their podcasts, actively engaging in a social constructivist learning approach. The audio conversation was recorded in a mock roleplay setting between health experts and laypersons, both played by students. The content comprised scientific aspects, conflicting opinions and contemporary issues on the vaccine topic, in the context of a lay-audience scenario provided in the assignment. The packaged podcast was graded for soundness of content, roleplaying, ability to engage the listener and creativity. Student perspectives and feedback were collected before and after the assignment through short online surveys comprising open-ended and Likert questions. Pairwise analysis showed improved digital literacy, improved confidence in students’ own communication skills and preference for podcast assignments (P

- Abstract
INTRODUCTION: Non-responsive coeliac disease (NRCD), where symptoms and enteropathy persist despite a prolonged gluten-free diet (GFD), is common. Refractory coeliac disease (RCD), characterised by malabsorption and extensive enteropathy, is rare but serious. In both, treatment options are limited. Topical budesonide may help and an open capsule format promoting proximal small intestinal delivery may be advantageous. AIM: To describe the effect of budesonide and its presentation on mucosal healing, symptoms, and tolerability in NRCD and RCD. METHODS: A retrospective cohort study of NRCD and RCD patients who received budesonide for enteropathy despite a strict GFD for over 12 months. Primary outcome was improvement in histology. Symptoms and adverse treatment effects were recorded. RESULTS: 50 patients with NRCD (n = 14; 86% F), RCD type 1 (n = 30; 60% F), and RCD type 2 (n = 6 based on aberrant duodenal T cells; 33% F) were identified. Common RCD symptoms were diarrhoea (68%), fatigue (40%), and weight loss (34%). 16 received closed capsule budesonide (CCB) 9 mg OD and 35 open capsule budesonide (OCB) 3 mg 3 times a day. Complete and partial mucosal healing was significantly higher after OCB compared to CCB (p < 0.001, Mann-Whitney U test). Symptom improvement was also significantly higher after OCB compared to CCB (p = 0.002, Mann-Whitney U test). Side effects were mild and self-limiting and were reported in 25% of both cohorts. CONCLUSION: OCB was well tolerated and associated with improvements in enteropathy (83%) and symptoms (90%) in NRCD and RCD. Our findings support OCB as the preferred 1st-line therapy for NRCD and RCD type 1.

Medicine ,Science - Abstract
Conservation areas are critical for biodiversity conservation, but few citizen science studies have evaluated their efficiency. In the absence of thorough survey data, this study assessed which species benefit most from conservation areas using citizen science bird counts extracted from the Atlas of Living Australia. This was accomplished by fitting temporal models using citizen science data taken from ALA for the years 2010-2019 using the INLA approach. The trends for six resident shorebird species were compared to those for the Australian Pied Oystercatcher, with the Black-fronted Dotterel, Red-capped Dotterel, and Red-kneed Dotterel exhibiting significantly steeper increasing trends. For the Black-fronted Dotterel, Masked Lapwing, and Red-kneed Dotterel, steeper rising trends were recorded in conservation areas than in other locations. The Dotterel species' conservation status is extremely favourable. This study demonstrates that, with some limits, statistical models can be used to track the persistence of resident shorebirds and to investigate the factors affecting these data.

Background and Purpose: Stroke can have a devastating impact on the mental and physical health of stroke survivors and their carers. We aimed to evaluate the effectiveness of a novel psychosocial intervention designed to improve health outcomes in both groups. Methods: We conducted a randomized controlled trial of a personalized psychosocial intervention (eight 1-hour weekly sessions plus one booster) compared to usual care for adult stroke survivors and carers. Participants recruited from hospital services and community referrals completed questionnaires at baseline, 3, 6, and 12 months. Primary outcomes were quality of life and self-efficacy; secondary outcomes were depressive and anxiety symptoms, coping, illness perception, work and social adjustment, carer strain, and carer satisfaction. Mixed-effect model repeated measures analysis between groups and across time was conducted. Results: Of the 173 participants recruited (89 stroke survivors; 84 carers), a total of 137 participants���73 stroke survivors (intervention n = 42; usual care n = 31) and 64 carers (intervention n = 35; usual care n = 29)���underwent analysis up to 12 months. No statistically significant differences were found in the primary outcomes between groups over time, though a significant improvement in carer satisfaction was found at 6 months in the intervention group compared to the usual care group. Conclusion: A personalized psychosocial intervention resulted in a significant improvement in carer satisfaction at 6 months but in no other outcomes. A lack of available services and barriers to social engagement may have impeded the effectiveness of this intervention.

- Abstract
Psychological distress is often observed in patients with gastrointestinal illness. To date, there has been limited research conducted to assess the prevalence and impact of post-traumatic stress disorder (PTSD) in gastrointestinal cohorts. The aim of this systematic review is to review the evidence for the prevalence of PTSD in gastrointestinal cohorts versus comparator groups (healthy controls and chronic illness groups), predictive factors associated with the development and management of PTSD and the impact on patient outcomes. Adult studies were identified through systematic searches of eight databases (MEDLINE, Embase, Emcare, PsycINFO, Ovid Nursing, CINAHL, Informit Health Collection, and Cochrane Library) in February 2020. The overall pooled prevalence rate of PTSD in GI cohorts was 36%; however, the prevalence rate in non-veteran-specific gastrointestinal cohorts of 18% across all GI classification groups is likely to be the more representative rate. The non-gastrointestinal chronic illness cohort PTSD prevalence rate was 11%. Predictors identified in the development of post-traumatic stress in gastrointestinal cohorts include: female gender, poor social support, life adversity, subjective pain, and dietary choices. Post-traumatic stress was found to exacerbate gastrointestinal symptoms in a Crohn's Disease sample, whereby disease exacerbation was four times in those who met the criteria for probable PTSD. Post-traumatic stress symptoms affect around one in five individuals (non-veteran status) with a gastrointestinal condition. Further research is needed to understand the psychological and biological mechanisms by which PTSD increases the risk of developing and exacerbating gastrointestinal symptoms.Copyright © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature.

- Abstract
This study evaluated the mediating role of self-efficacy, coping, depression and anxiety on the relationship between illness perceptions and quality of life in stroke survivors (n = 72; 32 females; mean [SD] age 65.09 [14.14] years; male mean [SD] age 69.83 [11.81]). Illness perceptions (Brief Illness Perceptions Questionnaire; BIPQ), coping styles (Carver Brief-COPE scale; B-COPE), depression/anxiety (Hospital Anxiety and Depression Scale; HADS), self-efficacy (General Self-Efficacy Scale; GSE) and quality of life (Assessment of quality of life; AQOL-6D) were analysed. Correlation analyses showed illness perception, maladaptive coping, self-efficacy, depression and anxiety to have a significant negative relationship with quality of life. Mediation analyses showed that while maladaptive coping and self-efficacy did not mediate the relationship between illness perception and quality of life, depression and anxiety did. The final model explained 76.74% of the variance in quality of life. Although based on a relatively small sample size, these results provide evidence for the important role of psychosocial factors in quality of life in post-stroke cohorts.

29. Is There a Role for Use of Levonorgestrel Intrauterine System in Women with Chronic Pelvic Pain?

Anpalagan, Apputhurai and Condous, George
- Abstract
Abstract: This review focuses on the available evidence for the use of levonorgestrel (LNG) intrauterine system (IUS) in women with chronic pelvic pain (CPP). We have searched MEDLINE, Pubmed, Embase, and the Cochrane electronic library with the keywords “chronic pelvic pain,” “endometriosis,” “Mirena IUS,” and “levonorgestrel IUS” from 1956 through April 2008. Review articles, randomized trials, prospective cohort studies, and retrospective studies were analyzed and the available evidence included in this review. Case reports were not included in the analysis. Laparoscopic surgery was shown to be useful in clarifying the underlying cause in women with CPP, with 70% having abnormal findings at laparoscopy. Endometriosis, particularly deep infiltrating endometriosis, is found in 40% to 60% of women with dysmenorrhea. Laparoscopic excision of endometriosis was shown to be associated with improvement of symptoms in 70% to 80% of women. Up to 36% need repeated surgery during a 5-year period after the primary procedure. The absolute reduction in recurrence of dysmenorrhea in women who also had the LNG IUS inserted at the time of surgery was 35% (95% CI 9%–61%). The LNG IUS was shown also to reduce the blood flow in the uterine artery and the subendometrial spiral arteries. This may explain the reduction in primary dysmenorrhea in women who have the LNG IUS inserted. Insertion of the LNG IUS at the time of primary laparoscopic surgery in women with CPP caused by endometriosis has the potential to reduce postoperative pain scores. This medical approach is also a promising alternative to repeated laparoscopic surgery especially in those women who have continuing symptoms after laparoscopic excision of endometriosis. This nonsurgical option could potentially reduce the rate of repeated laparoscopies in women with CPP and, in turn, reduce overall intervention rates. Although growing evidence exists that the LNG IUS can be useful in this group of women, large randomized controlled studies are needed to validate its benefits in day-to-day practice.

Gunarathne L, Apputhurai P, Nedeljkovic M, and Bhowmik J
- Abstract
In Sri Lanka, intimate partner violence (IPV) remains a major concern, particularly for married women. Women's education and empowerment are significant contributors to IPV. Despite this, there have been no recent studies exploring the complex relationship between education and multidimensions of empowerment in relation to IPV in Sri Lanka. Therefore, this research addresses this gap by exploring the complex pathways connecting married women's education and multidimensional empowerment to IPV. Using data from the 2019 Sri Lankan Women's Wellbeing Survey, this study included 1,165 married women. A path analysis based on structural equation modeling (SEM) was used to examine the complex interplay between distinct empowerment domains and IPV. The SEM results revealed both direct and indirect effects of women's education and empowerment on IPV experiences. Education is positively linked to age at marriage, employment status, and husbands' educational level, while inversely associated with accepting attitudes toward violence. Age at marriage plays a major role as a mediator, mediating the relationship between women's education and their involvement in decision-making, and the relationship between husbands' education and women's IPV experience. Moreover, the relationship between women's age at marriage and their IPV experiences was fully mediated by their decision-making ability, highlighting the importance of empowerment in decision-making. These findings underscore the need for targeted interventions that address the interconnected factors affecting IPV risk among married women in Sri Lanka, particularly focusing on education, empowerment, and marriage timing., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interests with respect to the authorship and/or publication of this article.

Technical assessments of these CAs focused on response accuracies and their ability to recognize, predict, and classify user emotions. While single-engine CAs demonstrated good accuracy, the hybrid engines achieved higher accuracy and provided more nuanced responses. Of the 19 studies, human evaluations were conducted in 16 (84%), with only 5 (26%) focusing directly on the CA's empathic features. All these papers used self-reports for measuring empathy, including single or multiple (scale) ratings or qualitative feedback from in-depth interviews. Only 1 (5%) paper included evaluations by both CA users and experts, adding more value to the process., Conclusions: The integration of CA design and its evaluation is crucial to produce empathic CAs. Future studies should focus on using a clear definition of empathy and standardized scales for empathy measurement, ideally including expert assessment. In addition, the diversity in measures used for technical assessment and evaluation poses a challenge for comparing CA performances, which future research should also address. However, CAs with good technical and empathic performance are already available to users of MH care services, showing promise for new applications, such as helpline services., (©Ruvini Sanjeewa, Ravi Iyer, Pragalathan Apputhurai, Nilmini Wickramasinghe, Denny Meyer.

- Abstract
Background: Sri Lankan married women have been reported to experience higher rates of intimate partner violence (IPV). However, research on its impact on mental health and how socio-demographic factors contribute to this association is limited. Therefore, this study aimed to examine the impact of IPV on the mental health of married women in Sri Lanka., Methods: In this study, data from 1611 married women who participated in the 2019 Sri Lankan Women's Wellbeing Survey were analyzed. Two binary outcomes were considered: married women's mental health and their suicidal ideation. Binary logistic regression models were used to assess the association between mental health and suicidal thoughts in relation to IPV while controlling for socio-demographic factors., Results: The results revealed that married women who experienced any form of violence by their spouse had a higher risk of having poor mental health conditions [AOR = 2.88 (2.20, 3.78)] and suicidal thoughts [AOR = 5.84 (4.10, 8.32)] compared to those who did not experience IPV., Conclusions: IPV is a substantial contributor to poor mental health and suicidal thoughts among Sri Lankan married women. There is an urgent need for policy interventions, such as community awareness programs, counseling services and enhanced legal protections for victims., (© The Author(s) 2024.

- Abstract
Objective: To determine the prevalence and associations between anxiety/depression, and gastrointestinal (GI) symptoms across gastroparesis and functional dyspepsia., Methods: Twenty adult studies were identified through systematic searches of three databases (PubMed, CINAHL and PsycINFO) in September 2023. Meta-analysis was performed to estimate the pooled prevalence rates of anxiety and depression across gastroparesis and functional dyspepsia, and to determine whether the associations of anxiety/depression and gastrointestinal (GI) symptoms differ in gastroparesis versus functional dyspepsia., Results: The overall pooled prevalence rate for anxiety was similar (χ
2 (1) = 2.45, p = .12) in gastroparesis (49%) and functional dyspepsia (29%). The overall pooled prevalence rate for depression in gastroparesis (39%), and functional dyspepsia (32%) was also similar (χ2 (1) = 0.81, p = .37). No significant relationship between anxiety and GI symptoms (r = 0.11) or depression and GI symptoms (r = 0.16) was found in gastroparesis, whilst significant, though weak, positive relationships between anxiety and GI symptoms (r = 0.30) and depression and GI symptoms (r = 0.32) were found in functional dyspepsia. The association between GI symptoms and anxiety, but not depression, across gastroparesis and functional dyspepsia was found to be significant (χ2 (1) = 5.22, p = .02)., Conclusion: Contributing to ongoing debate as to whether gastroparesis and functional dyspepsia are interchangeable syndromes, this review found that anxiety and depression prevalence was similar in both conditions. Psychological assessment and the utilisation of effective and holistic care in both conditions is therefore warranted., Competing Interests: Declaration of competing interest The authors received no funding and declare no conflicts of interest., (Copyright © 2024 The Authors.

- Abstract
Objective: Using the large Rome Foundation Global Epidemiology Survey dataset, the aim of this study was to evaluate the construct and convergent validity and internal consistency of the PHQ-4 across both gastrointestinal and non-gastrointestinal condition cohorts. Another aim was to provide descriptive information about the PHQ-4 including means, confidence intervals and percentage of caseness using a large representative sample., Methods: A cross-sectional survey was conducted in 26 countries. Confirmatory factor and internal consistency analyses were conducted across subsamples of patients with gastrointestinal conditions (i.e., disorders of gut-brain interaction [DGBI; any DGBI, individual DGBI, and DGBI region], gastroesophageal reflux disease (GERD), coeliac disease, diverticulitis, inflammatory bowel disease (IBD), cancer anywhere in the gastrointestinal tract, peptic ulcer) and those without a gastrointestinal condition. Convergent validity was also assessed via a series of Pearson's correlation coefficients with PROMIS (physical and mental quality of life), and PHQ-12 (somatisation)., Results: Based on 54,127 participants (50.9% male; mean age 44.34 years) confirmatory factor analysis indicated acceptable to excellent model fits for the PHQ-4 across all subsamples and individual DGBI and DGBI region (Comparative Fit Index >0.950, Tucker-Lewis Index >0.950, Root Mean Squared Error of Approximation <0.05, and Standardised Root Mean Square Residual <0.05). The PHQ-4 was found to demonstrate convergent validity (Pearson's correlation coefficients >±0.4), and good internal consistency (Cronbach's α > 0.75)., Conclusions: This study provides evidence that the PHQ-4 is a valid and reliable tool for assessing mental health symptomology in both gastrointestinal and non-gastrointestinal cohorts., Competing Interests: Declaration of competing interest The authors have no competing interests., (Copyright © 2024 The Authors.

- Abstract
Background: Brain fog is a subjective cognitive impairment commonly reported in coeliac disease. A standardised tool to define and assess it is an important unmet need., Aims: To develop a patient-informed tool to assess brain fog in coeliac disease to support clinical care, research and drug development., Methods: A pilot online study defined patient descriptors of brain fog. A second study evaluated the factor structure and performance of the scale across two-time points ('Now' and in the 'Past week'). One month later, participants were invited to repeat the study with two online cognitive processing tests, the Stroop task and the trail making test., Results: Among adults with treated coeliac disease, 37 (91.9% F) participated in the pilot study and 510 (88.8% F) in the second study of whom 99 repeated the study 1 month later with 51 completing cognitive testing. The most common brain fog descriptors were 'difficulty focusing', 'difficulty thinking' and 'difficulty finding the right words and communicating'. The 12-item scale reflects 'cognitive impairment' and 'somatic and affective experience' and demonstrates strong psychometric properties. It tracked with patients report of brain fog being present or absent across two-time points. It did not significantly correlate with the cognitive tests., Conclusion: The brain fog assessment and severity scale is the first patient-informed clinical outcomes assessment tool measuring brain fog in coeliac disease. It is brief and validated for two time-based formats. Further research coupling it with biomarker discovery is needed to confirm its validity as a predictor of cognitive performance., (© 2024 The Authors.

Objective: This study aimed to evaluate if a new Mental health IN DiabeteS Optimal Health Program (MINDS OHP) compared with usual care in adults with Type 1 and Type 2 diabetes would improve psychosocial outcomes including self-efficacy and quality of life.D esign and Main Outcome Measures This initial randomised controlled trial evaluated MINDS OHP compared with usual care. Participants were recruited through outpatient clinics and community organisations. The intervention group received nine sessions with assessments over twelve months. Primary outcomes were self-efficacy and quality of life. Secondary outcomes included diabetes distress and anxiety., Results: There were 51 participants in the control group (mean age = 52) and 55 in the intervention group (mean age = 55). There were significant main effects of time in general self-efficacy, diabetes distress, diabetes self-efficacy, and illness perceptions, however no significant between-group differences in primary or secondary outcomes. Post-hoc analyses revealed MINDS OHP improved diabetes self-efficacy for participants with mild to severe depression and anxiety, with a small effect., Conclusion: Initial evaluation found MINDS OHP was associated with improved diabetes self-efficacy for adults with diabetes, for people with mild to severe levels of distress, with small effect. Further research is required to explore whether this disease-specific, collaborative care-focused intervention benefits the mental health of people with diabetes.

- Abstract
Intimate Partner Violence (IPV) is a global problem and has been reported to be significantly higher for women in Low and Middle-Income Countries (LMICs). The researchers analyzed Demographic and Health Survey (DHS) data of married women in 20 LMICs to examine those most vulnerable to accepting IPV by investigating associated risk factors. The researchers revealed a higher level of acceptance of IPV among illiterate women from poorer households in remote areas. Using these findings, the authors provide insight into ensuring and enhancing the living standards of these vulnerable women by making education more readily accessible.

- Abstract
Intimate Partner Violence (IPV) is a global public health issue, with notably high prevalence rates observed within Low-and Middle-Income Countries (LMICs). This systematic review aimed to examine the risk factors and consequences associated with IPV against women in LMICs. Following PRISMA guidelines, we conducted a systematic review using three databases: Web of Science, ProQuest Central, and Scopus, covering the period from January 2010 to January 2022. The study included only peer-reviewed journal articles in English that investigated IPV against women in LMICs. Out of 167 articles screened, 30 met the inclusion criteria, comprising both quantitative and mixed-method studies. Risk factors of IPV were categorised as: demographic risk factors (23 studies), family risk factors (9 studies), community-level factors (1 studies), and behavioural risk factors (14 studies), while consequences of IPV were categorised as mental health impacts (13 studies), physical impacts (5 studies), and societal impacts (4 studies). In this study, several risk factors were identified including lower levels of education, marriage at a young age, poor wealth indices, rural residential areas, and acceptance of gender norms that contribute to the prevalence of IPV in LMICs. It is essential to address these factors through effective preventive policies and programs. Moreover, this review highlights the necessity of large-scale, high-quality policy-driven research to further examine risk factors and consequences, ultimately guiding the development of interventions aimed at preventing IPV against women in LMICs., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Gunarathne et al.

- Abstract
Chronic kidney disease (CKD) negatively impacts psychological well-being and quality of life (QoL). Underpinned by the Common Sense Model (CSM), this study evaluated the potential mediating role of self-efficacy, coping styles and psychological distress on the relationship between illness perceptions and QoL in patients living with CKD. Participants were 147 people with stage 3-5 kidney disease. Measures included eGFR, illness perceptions, coping styles, psychological distress, self-efficacy and QoL. Correlational analyses were performed, followed by regression modelling. Poorer QoL was associated with greater distress, engagement in maladaptive coping, poorer illness perceptions and lower self-efficacy. Regression analysis revealed that illness perceptions predicted QoL, with psychological distress acting as a mediator. The proportion of variance explained was 63.8%. These findings suggest that psychological interventions are likely to enhance QoL in CKD, if they target the mediating psychological processes associated with illness perceptions and psychological distress.

- Abstract
Background: The Rome Foundation Global Epidemiology Study on the disorders of gut-brain interaction (DGBI) was used to assess the national prevalence of all 22 DGBI, the percentage of respondents meeting diagnostic criteria for at least one DGBI, and the rates of comorbid anxiety, depression, and somatization in Australia and 25 other countries., Methods: The survey was conducted in Australia and 25 other countries through the Internet and included the Rome IV Diagnostic Questionnaire and an in-depth supplemental questionnaire., Key Results: Two thousand thirty-six Australian adults completed the survey nationwide: mean age 47.34 ± 17.00 years, 50.15% males. Overall, 38.67% of Australians met criteria for at least one DGBI, with unspecified functional bowel disorder (8.01%) and then functional constipation (7.71%) being the most prevalent. For those Australians with at least one DGBI, rates of anxiety, depression, and somatization where high (26.58%, 28.96%, and 63.10%, respectively), with functional chest pain having the highest rates of anxiety (55.00%) and depression (57.50%), and irritable bowel syndrome (mixed) having the highest somatization rate (75.86%). The odds of having a DGBI increased with greater anxiety (OR: 1.09, CI 95%: 0.97, 1.23), depression (OR: 1.17, CI 95%: 1.04, 1.32), and somatization (OR: 1.17, CI 95%: 1.14, 1.20) symptom severity., Conclusions and Inferences: The current study represents the most comprehensive epidemiological exploration of DGBI and mental health in Australia to date, including their prevalence and distributions across sex and age, associations between DGBI and anxiety, depression, and somatization. The findings warrants future comparisons between population characteristics and health care systems differences in order to reduce the burden of DGBI and mental illness worldwide., (© 2023 The Authors.

- Abstract
Background and Aims: Post traumatic stress disorder (PTSD) is common in individuals with inflammatory bowel diseases (IBD). Living with a medical condition has been linked to the development of PTSD and to adversely impact patient outcomes. The aim of this study is to extend the common sense model (CSM) and evaluate trauma as an additional psychosocial process in the relationship between IBD symptoms and quality of life (QoL)., Method: A cross-sectional online study exploring trauma and IBD was performed., Results: 68 (32.2%) of the sample met the criteria for PTSD. Of this trauma group, 37 (54.4%) reported IBD related trauma, 21 (30.9%) reported non-IBD related trauma and 10 (14.7%) did not identify the trauma type. A structural equation model (SEM) based upon the CSM was found to have an excellent fit (χ2 (3)=1.10, p=0.35, RMSEA=0.02, SRMR=0.02, CFI=1.00, GFI=0.99). Results showed that trauma symptoms partially mediated the relationship between illness perceptions and QoL and fully mediated the relationship between maladaptive coping and QoL., Conclusion: This study extended the CSM and found that trauma symptoms functioned as a mediator between IBD activity and QoL. These results highlight the need for a holistic approach including psychological assessment and intervention in IBD.

- Abstract
Conservation areas are critical for biodiversity conservation, but few citizen science studies have evaluated their efficiency. In the absence of thorough survey data, this study assessed which species benefit most from conservation areas using citizen science bird counts extracted from the Atlas of Living Australia. This was accomplished by fitting temporal models using citizen science data taken from ALA for the years 2010-2019 using the INLA approach. The trends for six resident shorebird species were compared to those for the Australian Pied Oystercatcher, with the Black-fronted Dotterel, Red-capped Dotterel, and Red-kneed Dotterel exhibiting significantly steeper increasing trends. For the Black-fronted Dotterel, Masked Lapwing, and Red-kneed Dotterel, steeper rising trends were recorded in conservation areas than in other locations. The Dotterel species' conservation status is extremely favourable. This study demonstrates that, with some limits, statistical models can be used to track the persistence of resident shorebirds and to investigate the factors affecting these data., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Objective: Psychosocial factors likely play a substantial role in the well-being of those living with coeliac disease, especially during the COVID-19 pandemic, however, little research has examined well-being in this cohort using an integrated socio-cognitive model. This study had two aims: (1) Examine changes in gastrointestinal symptoms, psychosocial factors, and well-being outcomes (i.e., psychological distress, quality of life [QoL]) associated with the pandemic, (2) Examine the interrelationship of these variables across timepoints using the Common Sense Model (CSM)., Methods: 1697 adults with coeliac disease (Time 1, pre-pandemic; 83.1% female, mean age = 55.8, SD = 15.0 years) and 674 follow-up participants (Time 2, pandemic; 82.8% female, mean age = 57.0, SD = 14.4 years) completed an online questionnaire. Hypotheses were tested using repeated measures MANOVA and cross-lagged panel model analyses., Results: Participants reported improved QoL, and reduced gastrointestinal symptoms, negative illness perceptions and maladaptive coping from pre-pandemic to during the pandemic. There was no significant change in pain catastrophising or psychological distress. Cross-lagged effects showed gastrointestinal symptoms to predict negative illness perceptions, which in turn were predictive of poorer outcomes across all variables except pain catastrophising. Consistent with the CSM, there was a reciprocal relationship between illness perceptions and QoL over time. Maladaptive coping and pain catastrophising demonstrated limited predictive utility., Conclusion: The COVID-19 pandemic appears to have had a small beneficial effect across several indices of well-being among adults with coeliac disease. Cross-lagged relationships highlight illness perceptions as a predictor of well-being outcomes and a potential target for psychosocial interventions., (Copyright © 2021 Elsevier Inc.

- Abstract
Background: Inflammatory bowel disease is associated with poor quality of life. The aim of the cross-sectional study was to extend the common sense model to explore the impact of inflammatory bowel disease activity on quality of life and the potential mediating roles of illness perceptions, visceral sensitivity, coping styles, acceptance, and psychological distress., Methods: A total of 141 inflammatory bowel disease patients (86 with Crohn's disease and 55 with ulcerative colitis; 74 males, 65 females, and 2 gender non-specific, mean age 40.43 years) from 2 metropolitan hospital inflammatory bowel disease outpatient clinics participated. Measures included disease activity (Crohn's Disease Activity Index, Simple Clinical Colitis Activity Index), illness perceptions (Brief Illness Perceptions Questionnaire), visceral sensitivity (Visceral Sensitivity Index), coping styles (Brief Coping Operations Preference Enquiry), acceptance (Acceptance and Action Questionnaire-II), psychological distress (Depression, Anxiety, and Stress Scale), and European Health Interview Survey-Quality of Life (EUROHIS-QoL)., Results: A structural equation model of the extended common sense model was found to have a good fit (χ2(10) = 10.07, P = .43, root mean square error of approximation = 0.01, standardized root mean residual = 0.04, comparative index fit = 1.00, Tucker-Lewis index = 1.00, goodness-of-fit = 0.98). After controlling for irritable bowel syndrome diagnosis, the impact of disease activity on quality of life was statistically mediated by illness perceptions, maladaptive coping styles, and psychological distress. In addition, visceral sensitivity bordered on influencing the impact of disease activity and illness perceptions on quality of life through psychological distress., Conclusions: This study demonstrates that together with illness perceptions and coping styles, visceral sensitivity plays an important role in an individual's adaption to living with inflammatory bowel disease.

- Abstract
Background: Coeliac disease is a chronic gastrointestinal condition associated with an increased risk of psychiatric comorbidity, and diminished quality of life. Ongoing gastrointestinal symptomatology is frequently reported post-diagnosis, despite undertaking a gluten-free diet., Purpose: To examine the role of psychosocial factors in mediating the relationship between gastrointestinal symptoms and quality of life, using a cross-sectional structural equation modelling mediation analysis guided by the Common-Sense Model., Methods: 1697 adults with coeliac disease (83.1% female, mean age = 55.79, SD = 14.98 years) completed an online questionnaire. Measures included gluten-free diet adherence, gastrointestinal symptoms, illness perceptions, coping, gastrointestinal-specific anxiety, pain catastrophising, psychological flexibility, psychological distress, and quality of life., Results: A structural equation model was developed explaining 50.6% of the variation in quality of life and demonstrating good fit (χ2 (2) = 8.54, p = .014, χ2/N = 4.27, RMSEA = 0.04, SRMR = 0.01, CFI = 0.999, TLI = 0.98, GFI = 0.999). Gastrointestinal symptoms directly affected quality of life, and indirectly, via negative illness perceptions, maladaptive coping, pain catastrophising, and psychological distress., Conclusion: Psychosocial processes may affect adjustment in coeliac disease by mediating the relationship between gastrointestinal symptoms and quality of life. Individuals living with coeliac disease may benefit from interventions targeting maladaptive psychosocial factors., (Copyright © 2021 Elsevier Inc. All rights reserved.)

- Abstract
Objective: The COVID-19 pandemic has had a significant impact on mental health across the globe. People living with a chronic gastrointestinal (GI) disorder might be particularly at risk of mental health complications given higher rates of comorbid anxiety and depression compared to the healthy population. As GI disorders affect up to 40% of the population worldwide, this international collaborative study seeks to evaluate the extent of the impact of the COVID-19 pandemic on GI symptoms specifically and more generally on the well-being of those living with chronic GI conditions., Methods: A longitudinal survey with three time points (baseline, 6-month, and 12-month) will be conducted online. Adult participants with GI disorders from multiple countries will be recruited via patient associations, social media advertising, utilizing snowball sampling. Participants will be invited to complete a battery of questionnaires including demographic and health parameters, and measures of gastrointestinal symptoms, fear of COVID-19, perceived impact of COVID-19, illness perceptions, coping, depression, anxiety, stress, catastrophizing, and quality of life, using validated measures where available. Statistical analyses will include univariate descriptive models, multivariate models utilizing regression, mediation, and moderation, and latent growth models., Conclusions: This project may present novel information to the field of psychogastroenterology and may provide crucial information regarding the areas of impact for individuals with GI disorders during and following the pandemic. Further, this information can guide healthcare providers and patient associations on how to target support related to the pandemic mental health sequelae for these patients., (Copyright © 2021 Elsevier Inc.

- Abstract
Background: Individuals living with coeliac disease generally experience a remission of symptoms after adopting the gluten-free diet but often report substantial treatment burden and ongoing quality of life issues. Psychosocial factors have been suggested to play a significant role in post-diagnosis quality of life but have yet to be systematically reviewed., Aim: To review the evidence for psychosocial factors associated with quality of life in adult coeliac disease cohorts., Methods: Studies were identified via systematic searches of eight databases (MEDLINE, Embase, Emcare, PsycINFO, Ovid Nursing, CINAHL, Informit Health Collection, Cochrane Library) in May 2019., Results: Fourteen studies were included involving 3372 participants (80.2% female, mean age = 46.4 years). Symptoms of depression and anxiety were the most examined psychosocial factors across all studies. Quality of life was differentially associated with psychological distress, illness perceptions, coping, and attitudes/behaviours regarding food and the gluten-free diet., Conclusion: Several psychosocial factors are associated with quality of life in adults living with coeliac disease. Current evidence suggests these factors are interrelated and may influence quality of life directly, via reduced psychological well-being, and indirectly, via reduced adherence to the gluten-free diet. Future research is needed to examine these processes concurrently, with the aim of elucidating the psychosocial mechanisms underlying post-diagnosis well-being and identifying potential targets for psychosocial intervention., (Copyright © 2021 Elsevier Inc.

- Abstract
Background and Aims: The aim of this paper was to undertake a systematic review of the research utilizing the Common Sense Model (CSM) involving IBD cohorts to explain the psychosocial processes, including illness perceptions and coping styles, that underpin patient reported outcomes (PROs) - psychological distress (PD) and quality of life (QoL)., Methods: Adult studies were identified through systematic searches of 8 bibliographic databases run in August 2020 including Medline, Embase, and PsychINFO. No language or year limits were applied., Results: Of 848 records identified, 516 were selected with seven studies evaluating the CSM mediating pathways for final review (n = 918 adult participants). Consistent with the CSM, illness perceptions were associated with PD and QoL in six and five studies respectively. Illness perceptions acted as mediators, at least partially, on the relationship between IBD disease activity and PD and/or QoL in all seven studies. Coping styles, predominantly maladaptive-based coping styles, were found to act as mediators between illness perceptions and PD and/or QoL in five studies. Perceived stress was identified in one study as an additional psychosocial process that partially explained the positive influence of illness perceptions on PD, and a negative impact on QoL. Five studies were classified as high quality and two as moderate., Conclusions: The CSM can be utilised in IBD cohorts to evaluate key psychosocial processes that influence PROs. Future research should explore additional psychosocial processes within the CSM and evaluate the efficacy of targeting CSM processes to promote psychological well-being and QoL in IBD cohorts., (Copyright © 2020 Elsevier Inc.

- Abstract
Diabetes has a significant negative impact on mental health and quality of life (QoL). Underpinned by the Common Sense Model (CSM) the mediating role of coping patterns, self-efficacy, anxiety and depression symptoms on the relationship between illness perceptions and QoL in patients diagnosed with diabetes was evaluated. A total of 115 participants with diabetes (56, Type 1; 59, Type 2), 51% female and an average age of 52.69 (SD = 15.89) in Australia completed self-report measures of illness perceptions and psychological wellbeing. Baseline measures included illness perceptions, coping styles, psychological distress (anxiety and depression symptoms), self-efficacy, and quality of life. Mediating relationships were measured using structural equation modelling. A model of good fit was identified explaining 51% of the variation in QoL. Illness perceptions directly influenced QoL, maladaptive coping, self-efficacy, and anxiety symptoms. The relationship between illness perceptions and QoL was partially mediated by anxiety; illness perceptions and depression was fully mediated by maladaptive coping and self-efficacy; and self-efficacy and QoL was partially mediated by depressive symptoms. Findings provide validation of the CSM in a diabetes cohort. Psychological interventions likely to have the most benefit on psychological distress and QoL are those targeting mediating psychological processes, including maladaptive coping and self-efficacy.

- Abstract
Autism and schizophrenia spectrum research is typically based on coarse diagnostic classification, which overlooks individual variation within clinical groups. This method limits the identification of underlying cognitive, genetic and neural correlates of specific symptom dimensions. This study, therefore, aimed to identify homogenous subclinical subgroups of specific autistic and schizotypal traits dimensions, that may be utilised to establish more effective diagnostic and treatment practices. Latent profile analysis of subscale scores derived from an autism-schizotypy questionnaire, completed by 1678 subclinical adults aged 18-40 years (1250 females), identified a local optimum of eight population clusters: High, Moderate and Low Psychosocial Difficulties; High, Moderate and Low Autism-Schizotypy; High Psychosis-Proneness; and Moderate Schizotypy. These subgroups represent the convergent and discriminant dimensions of autism and schizotypy in the subclinical population, and highlight the importance of examining subgroups of specific symptom characteristics across these spectra in order to identify the underlying genetic and neural correlates that can be utilised to advance diagnostic and treatment practices., (Copyright © 2018 Elsevier B.V.
