Campylobacter jejuni and Campylobacter coli infections are the leading cause of foodborne gastroenteritis in high-income countries. Campylobacter colonizes a variety of warm-blooded hosts that are reservoirs for human campylobacteriosis. The proportions of Australian cases attributable to different animal reservoirs are unknown but can be estimated by comparing the frequency of different sequence types in cases and reservoirs. Campylobacter isolates were obtained from notified human cases and raw meat and offal from the major livestock in Australia between 2017 and 2019. Isolates were typed using multi-locus sequence genotyping. We used Bayesian source attribution models including the asymmetric island model, the modified Hald model, and their generalizations. Some models included an "unsampled" source to estimate the proportion of cases attributable to wild, feral, or domestic animal reservoirs not sampled in our study. Model fits were compared using the Watanabe-Akaike information criterion. We included 612 food and 710 human case isolates. The best fitting models attributed >80% of Campylobacter cases to chickens, with a greater proportion of C. coli (>84%) than C. jejuni (>77%). The best fitting model that included an unsampled source attributed 14% (95% credible interval [CrI]: 0.3%-32%) to the unsampled source and only 2% to ruminants (95% CrI: 0.3%-12%) and 2% to pigs (95% CrI: 0.2%-11%) The best fitting model that did not include an unsampled source attributed 12% to ruminants (95% CrI: 1.3%-33%) and 6% to pigs (95% CrI: 1.1%-19%). Chickens were the leading source of human Campylobacter infections in Australia in 2017-2019 and should remain the focus of interventions to reduce burden.

OBJECTIVES
Negative attributions pertain to judgments of intent, hostility, and blame regarding others' behaviors. This study compared negative attributions made by people with and without traumatic brain injury (TBI) and examined the degree to which these negative attributions predicted angry ratings in response to situations.
SETTING
Outpatient rehabilitation hospital.
PARTICIPANTS
Forty-six adults with moderate to severe TBI and 49 healthy controls.
DESIGN
Cross-sectional study using a quasi-experimental research design.
MAIN MEASURES
In response to hypothetical scenarios, participants rated how irritated and angry they would be, and how intentional, hostile, and blameworthy they perceived characters' behaviors. There were 3 scenario types differentiated by the portrayal of characters' actions: benign, ambiguous, or hostile. All scenarios theoretically resulted in unpleasant outcomes for participants.
RESULTS
Participants with TBI had significantly higher ratings for feeling "irritated" and "angry" and attributions of "intent," "hostility," and "blame" compared with healthy controls for all scenario types. Negative attribution ratings accounted for 72.4% and 65.3% of the anger rating variance for participants with and without TBI, respectively.
CONCLUSION
People with TBI may have negative attribution bias, in which they disproportionately judge the intent, hostility, and blameworthiness of others' behaviors. These attributions contributed to their ratings of feeling angry. This suggests that participants with TBI who have anger problems should be evaluated for this bias, and anger treatments should possibly aim to alter negative attributions. However, before implementing clinical practice changes, there is a need for replication with larger samples, and further investigation of the characteristics associated with negative attribution bias.

The identification and diagnosis of children with autism currently rely on behavioral presentation and developmental history. Cultural norms and other socio-demographic factors can influence what is expected or non-expected behaviors in a developing child. Perceptions, beliefs, and causal attribution of early signs can influence families' help-search behaviors. Lack of recognition of autism's first manifestations can critically delay the age of diagnosis, the provision of informed guidance to families, and the implementation of adapted interventions during the critical period of early development. Furthermore, a lack of understanding of early signs as the manifestations of a developmental condition may increase stigma and non-conventional explanations. Still, cultural and socio-demographic factors are largely understudied, particularly in low-and middle-income settings. Based on the hypothesis that non-specialists such as family members and friends are one of the first sources of referral in Latin American contexts, we aimed to study the general population's perceptions and the explanatory causes of autism's early signs. One-hundred-and-eighty-three Ecuadorian adults responded to a questionnaire developed for this study, describing sixteen ASD-related behaviors. Results indicated that, with the exemption of language impairment and self-injurious behaviors, a substantial proportion of participants did not endorse many behaviors as "concerning and requiring professional attention." Also, language impairment was the only behavior identified as related to a developmental disorder. Additionally, most participants attributed the majority of behaviors listed in the questionnaire to causes unrelated to ASD, such as child personality. We discuss the impact of those findings in clinical practice and on awareness programs.

This study investigates the associations of adolescents callous-unemotional traits with moral constructs and the interplay of various outcomes. The present study builds on the lack of research and focuses on the longitudinal relationships between CU-traits, moral identity, moral emotion attribution and externalizing behavior problems in adolescence. The included variables were collected at test time points T1 and T2. To determine the predictive, and stability links among the variables, a cross-lagged model in SPSS AMOS 26 was conducted. Time stability path estimates were moderate to highly stable over time for all included variables. Significant cross lagged paths of moral identity on moral emotion attribution, CU-traits on moral identity, externalizing behavior problems on moral emotion attributions and externalizing behavior problems on CU-traits, could be found.

BACKGROUND
Adherence to adjuvant endocrine therapy (ET) influences breast cancer survival. Because ET side effects are frequently cited as reasons for nonadherence, understanding how perceptions and motivations in relation to ET are associated with symptom attribution can help promote timely symptom management.
MATERIALS AND METHODS
Participants were 2,086 breast cancer survivors recruited through the Army of Women registry who were current tamoxifen or aromatase inhibitor (AI) users. Participants reported whether they were bothered by each of 47 symptoms during the past month and whether they thought each symptom was related to taking ET. Frequencies of overall symptoms and symptoms attributed and misattributed to ET were calculated, and linear regression was used to assess sociodemographics, emotions, and illness perceptions as predictors of symptoms attributed to ET.
RESULTS
Women attributed a mean of 8.9 symptoms and misattributed a mean of 1.5 symptoms to ET. In the multivariable analysis, younger age, a more recent diagnosis, AI use (vs. tamoxifen), anxiety, depressive symptoms, more ET-related negative emotions, more concern about long-term ET use, and greater perceived ET necessity were independently associated with attribution of more symptoms to ET. More perceived ET necessity was associated with correctly attributing symptoms to ET, whereas higher depressive symptoms and more concern about ET use were associated with misattribution of symptoms to ET.
CONCLUSION
Given that many women perceive a range of symptoms as a consequence of ET, attention to these symptoms may reduce symptom burden and improve quality of life, potentially improving ET adherence and optimizing survival.
IMPLICATIONS FOR PRACTICE
Many breast cancer survivors on endocrine therapy (ET) experience a range of side effects while taking ET. Targeting potentially modifiable factors associated with attributing a greater number of symptoms to ET, including perceived need for ET, concerns about long-term ET use, negative emotions toward ET, and symptoms of anxiety and depression, may reduce symptom burden and improve quality of life.

BACKGROUND
Identifying which exposures cause disease and quantifying their impacts is essential in promoting and monitoring public health. When multiple exposures are involved, measuring individual contributions becomes challenging.
METHODS
The authors propose a disease attribution method based on aggregate data or summary statistics of individual-level data, possibly from multiple data sources.
RESULTS
Using the proposed method, the burden of disease is apportioned to the independent and interaction effects of each of its major risk factors and all the other factors as a whole. This scheme guarantees that 100% is the total share of the burden.
CONCLUSION
The calculation is simple and straightforward; therefore, it is recommended for use in studies on disease burden.

BACKGROUND AND PURPOSE
Despite the notable benefits of physical activity for chronic pain, a large proportion of patients with chronic pain report that they do not receive activity-related recommendations from their providers. Research suggests that patient factors such as weight and gender influence activity-related recommendations for chronic pain. Research also suggests that appraisals of the intensity and cause of pain may explain these weight and gender effects. We investigated the influence of patient weight and gender on observers' likelihood of recommending activity-related treatments for pain. We also explored the mediating effects of observers' ratings of pain severity and the extent to which pain was due to medical and lifestyle factors (pain attribution).
PATIENTS AND METHODS
Healthy young adults (N=616; 76% female) viewed videos (Ghent Pain Videos of Daily Activities) and vignettes of 4 patients with chronic back pain performing a standardized functional task. Patients varied by gender (female, male) and weight (normal, obese), but were otherwise equivalent on demographic characteristics and pain behaviors. Participants rated how much pain they perceived the patients to be experiencing, the extent to which they attributed the pain to medical and lifestyle factors, and their likelihood of recommending exercise, physical therapy (PT), and rest.
RESULTS
Patient weight and gender significantly interacted to influence exercise, PT, and rest recommendations. Both pain intensity and pain attribution mediated the relationships between patient weight and activity recommendations; however, these mediation effects differed across gender and recommendation type.
CONCLUSION
Patient weight and gender influenced laypeople's activity recommendations for chronic pain. Moreover, the results suggest that observers' perceptions of pain intensity and pain attributions are mechanisms underlying these effects. If these findings are replicated in providers, interventions may need to be developed to reduce provider biases and increase their recognition of the benefits of physical activity for chronic pain.

The aim was to investigate behavioral reactions and event-related potential (ERP) responses in healthy participants under conditions of personalized attribution of emotional appraisal vocabulary to one-self or to other people. One hundred and fifty emotionally neutral, positive and negative words describing people's traits were used. Subjects were asked to attribute each word to four types of people: one-self, loved, unpleasant and neutral person. The reaction time during adjectives attribution to one-self and a loved person was shorter than during adjectives attribution to neutral and unpleasant people. Self-related adjectives induced higher amplitudes of the N400 ERP peak in the medial cortical areas in comparison with adjectives related to other people. The amplitude of P300 and P600 depended on the emotional valence of assessments, but not on the personalized attribution. The interaction between the attribution effect and the effect of emotional valence of assessments was observed for the N400 peak in the left temporal area. The maximal amplitude of N400 was revealed under self-attributing of emotionally positive adjectives. Our results supported the hypothesis that the emotional valence of assessments and the processing of information about one-self or others were related to the brain processes that differ from each other in a cortical localization or time dynamics.

BACKGROUND
Illness beliefs are significant contributors to health outcomes. Beliefs about the cause of physical symptoms are considered particularly important among those with medically unexplained symptoms and illnesses (MUS); yet little is known about causal beliefs among those with the most severe MUS (i.e., Veterans). The goal of the current study was to examine Veteran's causal attributions of their physical symptoms.
METHOD
A total of 91 combat Veterans with MUS were surveyed using a mixed-methods design about the cause of their physical symptoms, physical symptom severity, and PTSD symptoms. Causal attributions of physical symptoms were analyzed through thematic response analysis and grouped into categories. Chi-square analysis was used to assess the distribution of causal attribution types across Veterans with varying physical symptom severity and PTSD symptom severity.
RESULTS
Veterans with MUS reported an average of 7.9 physical symptoms, and attributed the cause of their symptoms to seven different categories ("Do not Know," "Stress/Mental Health," "Deployment/Environment," "Functional/Symptom," "Medically Explained," "Medically Unexplained Syndrome," and "Lifestyle"). Exploratory chi-square analysis revealed significant differences in causal attributions across physical symptom severity and severity of PTSD symptoms. Veterans with more severe PTSD and Veterans with more severe physical symptoms were more likely to attribute their MUS to stress/mental health or to a medically unexplained syndrome compared with those with low/no PTSD symptoms and physical symptom severity. Veterans with minimal PTSD and Veterans with minimal physical symptom severity were more likely to attribute the cause of their MUS to lifestyle choices (e.g., exercise/diet) compared with those with high PTSD and physical symptom severity.
CONCLUSION
Veterans with MUS endorse multiple, varied causal attributions for their physical symptoms, suggesting more complex causal beliefs than typically assumed. This has important implications for patient-provider communication and development of concordance around MUS treatment.

Paranoia is the exaggerated belief that harm will occur and is intended by others. Although commonly framed in terms of attributing malicious intent to others, recent work has explored how paranoia also affects social decision-making, using economic games. Previous work found that paranoia is associated with decreased cooperation and increased punishment in the Dictator Game (where cooperating and punishing involve paying a cost to respectively increase or decrease a partner's income). These findings suggest that paranoia might be associated with variation in subjective reward from positive and/or negative social decision-making, a possibility we explore using a preregistered experiment with U.S.-based participants (n = 2,004). Paranoia was associated with increased self-reported enjoyment of negative social interactions and decreased self-reported enjoyment of prosocial interactions. More paranoid participants attributed stronger harmful intent to a partner. Harmful intent attributions and the enjoyment of negative social interactions positively predicted the tendency to pay to punish the partner. Cooperation was positively associated with the tendency to enjoy prosocial interactions and increased with participant age. There was no main effect of paranoia on tendency to cooperate in this setting. We discuss these findings in light of previous research. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
