- We introduce the AusTraits database - a compilation of values of plant traits for taxa in the Australian flora (hereafter AusTraits). AusTraits synthesises data on 448 traits across 28,640 taxa from field campaigns, published literature, taxonomic monographs, and individual taxon descriptions. Traits vary in scope from physiological measures of performance (e.g. photosynthetic gas exchange, water-use efficiency) to morphological attributes (e.g. leaf area, seed mass, plant height) which link to aspects of ecological variation. AusTraits contains curated and harmonised individual- and species-level measurements coupled to, where available, contextual information on site properties and experimental conditions. This article provides information on version 3.0.2 of AusTraits which contains data for 997,808 trait-by-taxon combinations. We envision AusTraits as an ongoing collaborative initiative for easily archiving and sharing trait data, which also provides a template for other national or regional initiatives globally to fill persistent gaps in trait knowledge.

- The study aimed to document the impact of the COVID-19 pandemic on the health and well-being of individuals with past and current eating disorders (ED) in Sweden. We re-contacted participants with a known lifetime history of ED from two previous Swedish studies. Participants completed an online survey about health and functioning at baseline early in the pandemic (Wave 1 ca May/June 2020; N= 982) and six months later (Wave 2 Dec/Jan 2020/21; N= 646). Three important patterns emerged: 1) higher current ED symptoms were associated with greater anxiety, worry, and pandemic-related ED symptom increase; 2) patterns were fairly stable across time, although a concerning percentage (23%) who were symptom-free at Wave 1 reported the re-emergence of symptoms at Wave 2; and 3) only a minority of participants (<50%) with a current ED were in treatment, and of those in treatment, many reported fewer treatment sessions and decreased quality of care. The COVID-19 pandemic appears to pose serious health challenges for individuals with an ED, whether currently symptomatic or in remission. We encourage health service providers and patient advocates to be alert to the needs of individuals with ED and to take active measures to ensure access to appropriate evidence-based care both during and following the pandemic.

- Recent genome-wide association studies (GWAS) suggest that genetic factors play a key role in its development and expression and that anorexia nervosa (AN) might have both psychiatric and metabolic underpinnings. One hypothesis is that those with high genetic vulnerability to AN may experience negative energy balance (NEB) (i.e., expending more energy than you consume) in a positive manner, rendering self-starvation and excessive exercise exceptionally reinforcing. This “paradoxical” response to NEB may also complicate recovery. In the Polygenic risk of Anorexia nervosa and its Clinical Expression (PACE) study, we explored differences in clinical and phenomenological/experiential phenotypes (i.e., how patients reported their experience of illness) in 10 individuals with AN who were in the top decile of AN polygenic risk (PRS) and 10 individuals with AN who were in the lowest decile in the Swedish subsample of the Anorexia Nervosa Genetics Initiative (ANGI) study. We interviewed the participants in a double-blind study design using a structured interview guide focusing on the experience of AN, including experiences of NEB (e.g., hunger, satiety, dietary restriction), the development of symptoms, as well as the reactions of others including family members and treatment providers to patients’ experiences of NEB. All interviews have been coded and the blind will be broken in May 2023 at which point group comparisons will be analyzed. This is the first study, to our knowledge, to explore experiential impact of genetic risk. Findings may aid in understanding risk, clinical course, and individual experience of AN and contribute suggestions for tailoring interventions with input from genetic risk profiles.

- Anthropogenic sensory pollutants, such as noise, light and chemicals, are affecting biodiversity. This Perspective uses an understanding of animal sensory ecology to explore how these impacts can be mitigated. Global expansion of human activities is associated with the introduction of novel stimuli, such as anthropogenic noise, artificial lights and chemical agents. Progress in documenting the ecological effects of sensory pollutants is weakened by sparse knowledge of the mechanisms underlying these effects. This severely limits our capacity to devise mitigation measures. Here, we integrate knowledge of animal sensory ecology, physiology and life history to articulate three perceptual mechanisms-masking, distracting and misleading-that clearly explain how and why anthropogenic sensory pollutants impact organisms. We then link these three mechanisms to ecological consequences and discuss their implications for conservation. We argue that this framework can reveal the presence of 'sensory danger zones', hotspots of conservation concern where sensory pollutants overlap in space and time with an organism's activity, and foster development of strategic interventions to mitigate the impact of sensory pollutants. Future research that applies this framework will provide critical insight to preserve the natural sensory world.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Transdiagnostically relevant psychological traits associated with psychiatric disorders are increasingly being researched, notably in substance use and addictive behaviors. We investigated whether emotion dysregulation mediated by impulsivity and/or compulsivity could explain variance in binge eating, food addiction, self-starvation, and compulsive exercise, as well as alcohol use (addictive-like behaviors relevant to the obesity and eating disorder fields).METHOD: A general population sample of adults (N = 500, mean age = 32.5 years), females (n = 376) and males (n = 124), completed the Difficulties in Emotion Regulation Scale-16, the Trait Rash Impulsivity Scale, the Obsessive-Compulsive Inventory-Revised, the Eating Disorders Examination Questionnaire, the Self-Starvation Scale, the Exercise Dependence Scale, the Yale Food Addiction Scale, and the Alcohol Use Disorders Identification Test online. Besides gender comparisons and intercorrelations between measures, we used predefined multiple mediation models with emotion dysregulation as independent variable, impulsivity and compulsivity as parallel mediators, to investigate whether these factors contributed explanatory power to each addictive-like behavior as outcome, also using age and body mass index as covariates.RESULTS: Females scored higher than males on emotion dysregulation and the eating-related addictive-like behaviors food addiction, self-starvation, and binge eating. Intercorrelations between measures showed that emotion dysregulation and compulsivity were associated with all outcome variables, impulsivity with all except compulsive exercise, and the eating-related behaviors intercorrelated strongly. Mediation models showed full or partial mediation of emotion dysregulation for all behaviors, especially via compulsivity, suggesting a behavior-specific pattern. Mediation models were not affected by age or gender.DISCUSSION: Addictive-like behaviors seemed to be maintained by trait levels of emotion dysregulation, albeit channeled via trait levels of compulsivity and/or impulsivity. The role of emotion dysregulation may help us to understand why addictive-like behaviors can be difficult to change in both clinical and nonclinical groups, and may be informative for treatment-planning in patients where these behaviors are present. Our findings support adopting a more dimensional approach to psychiatric classification by focusing psychological facets such as those studied.

- INTRODUCTION: Binge eating is a common behaviour that is strongly linked to both obesity and eating disorder. There is evidence that binge eating commonly co-occurs with other problematic and addictive-like behaviours; however, this has not been explored systematically. The present study aimed to examine the relationship between binge eating, body weight, disordered eating behaviours and associated addictive-like behaviours, with particular attention paid to gender differences.METHOD: A community sample (N = 500; 75% female, Mage = 32.5 years) reported disordered eating behaviours (i.e. binge eating, purging, restriction of eating, compulsive exercise), body mass index (BMI), food addiction, starvation addiction, exercise dependence, tobacco use and alcohol consumption.RESULTS: 42% of females and 21% of males reported binge eating during the past four weeks. Binge eating was significantly associated with all investigated behaviours in females, and with purging, compulsive exercise and overweight/obesity in males. Controlling for BMI, self-starvation predicted binge eating in males (OR = 1.07), while food addiction (OR = 1.73) and alcohol dependence (OR = 1.11) predicted binge eating in females.CONCLUSIONS: The multiple associations between binge eating and addictive-like behaviors supports broad screening and generalized prevention efforts. Prevention efforts should reflect gender differences.

Tidskriftsartikel (refereegranskat)abstract
- Internet-based cognitive behavioral therapy (ICBT) for bulimic eating disorders has demonstrated clinical utility and cost efficiency, but is associated with low patient preference, low credibility, sizeable dropout and only moderate symptom reduction. To improve outcome it is imperative to learn more about who might benefit from internet-based interventions. To do this, the current study investigated the Five Factor Model of personality as predictor of outcome in patients with full or sub-threshold bulimia nervosa (n = 109). Patients in a randomized controlled trial of ICBT were assessed prior to and at the end of treatment. Patients showed significant symptom reduction over time (Cohen's d = 1.0, p < .001). Remission as well as overall symptom reduction was positively predicted by Openness to Experience and Conscientiousness. Binge eating cessation specifically, was positively predicted by Extraversion. The study supports the use of personality assessment for patient selection and outcome optimization in internet-based treatment of bulimic eating disorders.

Initial self-blame predicts eating disorder remission after 9 years.
- 2021

Ingår i: Journal of Eating Disorders. - : Springer Science and Business Media LLC. - 2050-2974. ; 9:1

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Research into predictors of outcome in eating disorders (ED) has shown conflicting results, with few studies of long-term predictors and the possible importance of psychological variables that may act as risk- and maintenance factors.AIM: To identify baseline predictors of ED remission nine years after initial clinical assessment using self-report measures of ED psychopathology, psychiatric symptoms, and self-image in a sample of adult ED patients (N = 104) treated at specialist units in Stockholm, Sweden. Sixty patients participated in the follow-up, of whom 41 patients (68%) had achieved remission.RESULTS: Results suggested that the only significant predictor of diagnostic remission after nine years was initial levels of self-blame.CONCLUSION: In order to ensure long-term recovery in ED it may be important for clinicians to widen their therapeutic repertoire and utilise techniques that reduce self-blame and increase self-compassion. It is difficult to predict how an eating disorder will develop, and research has found varying factors that affect the outcome of the condition. Recovery rates vary from nearly nil to over 90%. This variation could be explained by different research factors, but are more likely due to varying definitions of 'recovery', with less stringent definitions yielding high recovery rates and more stringent definitions yielding lower rates. The present study investigated whether the severity of eating disorder symptoms and other psychiatric symptoms could predict recovery nine years from first admission to specialised eating disorder care. Sixty patients at three eating disorder treatment units participated, and their scores on self-report measures of symptoms were used as predictor variables. Forty-one participants had no eating disorder diagnosis at nine-year follow-up. Most participants with binge-eating disorder had recovered, while the poorest outcome was found for anorexia nervosa with slightly over half of patients recovered after nine years. The only predictor for the nine-year outcome was a higher initial rating of self-blame, measured with the Structural Analysis of the Social Behavior. It was concluded that it may be important for clinicians to detect and address self-blame early in the treatment of eating disorders in order to enhance the possibility of recovery. Treatment should focus on reducing self-blame and increasing self-acceptance.
