RESUMEN

Zoos are an important repository of animals, which have a wide range of visual systems, providing excellent opportunities to investigate many comparative questions in sensory ecology. However, behavioural testing must be carried out in an animal welfare-friendly manner, which is practical for zoo staff. Here, we present a proof-of-concept study to facilitate behavioural research on the sensory ecology of captive primates. A system consisting of a tablet computer and an automated feeder connected wirelessly was developed and presented to captive primate species to evaluate interactions with and without previous training. A colour stimulus, analogous to the Ishihara test, was used to check the level of interaction with the device, supporting future studies on sensory ecology with zoo animals. Animals were able to use the system successfully and displayed signs of learning to discriminate between the visual stimuli presented. We identified no risk for small primates in their interactions with the experimental setup without the presence of keepers. The use of electronic devices should be approached with caution to prevent accidents, as a standard practice for environmental enrichment for larger animals (e.g., spider monkeys). In the long term, the system developed here will allow us to address complex comparative questions about the functions of different visual systems in captive animals (i.e., dichromatic, trichromatic, etc.).

RESUMEN

ISSUE ADDRESSED: Increasing and maintaining vaccination uptake is crucial for preventing and managing infectious diseases. In the context of the post-coronavirus disease 2019 (COVID-19) pandemic landscape, this paper examines the perceptions of immunisation implementers and policymakers to uncover the challenges and evidence gaps in routine immunisation efforts. METHODS: We conducted an online two-round modified Delphi survey with immunisation experts, senior public servants, policymakers, policy advisory groups, and representatives from peak bodies from across Australia. We asked respondents to outline what they see as the greatest challenges to increasing and maintaining uptake of recommended vaccines in Australia; the most difficult aspects of their work in vaccination; the largest evidence gaps in vaccine uptake; and the kinds of social and behavioural research they would like to see prioritised. RESULTS: The two most important challenges for increasing and maintaining vaccine uptake were effectively communicating the benefits of vaccines to parents and the public and ensuring accessible and affordable vaccination services. Participants strongly agreed that 'communication about the importance of vaccination' was the most difficult aspect of their work. Consistently important was the need to better engage specific population groups, such as culturally and linguistically diverse people, pregnant people, at risk cohorts, and health care providers. Social and behavioural research about 'how to effectively address hesitancy' was ranked highly among participants. CONCLUSIONS: Findings from this project help provide an understanding of the behavioural, social, ethical, and policy knowledge needs for immunisation policy and implementation in Australia. To respond to vaccine challenges, increase coverage and build public trust in vaccination, policymakers and governments should incorporate social research into vaccination programmes. SO WHAT?: Australia is preparing to launch a Centre for Disease Control. This study demonstrates the importance of integrating social, behavioural, ethical, and policy research into the fabric of this new enterprise. It underlines the need to capacity-build a workforce able to deliver high-quality research in these areas, address the needs of immunisation implementers and policymakers, and achieve good outcomes for Australians.

RESUMEN

Introduction: Many organizations are developing new contraceptive products and approaches that promote self-care including a microarray patch (MAP) that has the potential for self-administration with appropriate training. We studied women's perceptions of the MAP technology with the primary goal of providing feedback on product attributes to inform early technical design decisions regarding various MAP contraceptive products in development by MAP developers. Methods: Our study consisted of a qualitative phase with in-person In-Depth Interviews (IDIs) with a total of 60 women of reproductive age (WRA) and quantitative surveys, via face-to-face computer-assisted interviews of a total of 927 women in Ghana, Kenya and Uganda. Women's perceptions on 12 attributes of the MAP were assessed through written descriptions, a profile, and visual stimuli such as graphics and images. Results: Overall, the most widely preferred attribute set included: a hand-applied MAP, utilizing one circular patch, with a sticky backing, no larger than 2 cm diameter in size, applied by self, to the arm, offering sensory feedback (clicking sound and/or color change signals) to confirm enough pressure, successful application and removal, lasting 6 months with up to 12 months return to natural state of fertility. There is space to allow for variation in MAP designs (including the use of an applicator or provider administered MAP) if the design promotes and reflects the needs and expectations of users and providers. Discussion: The contraceptive MAP had a high and broad level of appeal amongst all groups of women who participated in the study and has a strong value proposition around important contraceptive needs such as ease of use, convenience, and discretion.

RESUMEN

Nominal group technique methods involve the use of structured activities within groups comprised of purposefully selected stakeholders (nominal groups), with the broad aim of achieving a level of consensus and prioritising information. In this paper, we will report how we facilitated nominal groups, using Microsoft Teams, to prioritise content for a theory-based behaviour change intervention to improve responses to clinically deteriorating patients. Our methods incorporated development and piloting of research materials, facilitation of online nominal groups with different stakeholders, and a structured approach to ranking behaviour change strategies. Practical suggestions are offered based on our experience of using this method in a virtual context.

RESUMEN

Artificial intelligence (AI) is often used to describe the automation of complex tasks that we would attribute intelligence to. Machine learning (ML) is commonly understood as a set of methods used to develop an AI. Both have seen a recent boom in usage, both in scientific and commercial fields. For the scientific community, ML can solve bottle necks created by complex, multi-dimensional data generated, for example, by functional brain imaging or *omics approaches. ML can here identify patterns that could not have been found using traditional statistic approaches. However, ML comes with serious limitations that need to be kept in mind: their tendency to optimise solutions for the input data means it is of crucial importance to externally validate any findings before considering them more than a hypothesis. Their black-box nature implies that their decisions usually cannot be understood, which renders their use in medical decision making problematic and can lead to ethical issues. Here, we present an introduction for the curious to the field of ML/AI. We explain the principles as commonly used methods as well as recent methodological advancements before we discuss risks and what we see as future directions of the field. Finally, we show practical examples of neuroscience to illustrate the use and limitations of ML.

RESUMEN

Individuals with autism spectrum disorder (ASD) exhibit atypical speech-in-noise (SiN) perception, but the scope of these impairments has not been clearly defined. We conducted a systematic review of the behavioural research on SiN perception in ASD, using a comprehensive search strategy across databases (Embase, Pubmed, Web of Science, APA PsycArticles, LLBA, clinicaltrials.gov and PsyArXiv). We withheld 20 studies that generally revealed intact speech perception in stationary noise, while impairments in speech discrimination were found in temporally modulated noise, concurrent speech, and audiovisual speech perception. An association with auditory temporal processing deficits, exacerbated by suboptimal language skills, is shown. Speech-in-speech perception might be further impaired due to deficient top-down processing of speech. Further research is needed to address remaining challenges and gaps in our understanding of these impairments, including the developmental aspects of SiN processing in ASD, and the impact of gender and social attentional orienting on this ability. Our findings have important implications for improving communication in ASD, both in daily interactions and in clinical and educational settings.

RESUMEN

INTRODUCTION AND OBJECTIVE: There is a knowledge gap in how dental clinicians recognise dental anxiety. The aim of this study was to identify, describe and generate concepts regarding this process. MATERIALS AND METHODS: Eleven semi-structured interviews were conducted with dental clinicians from the public dental service of Östergötland, Sweden. Purposive and theoretical sampling was used. Theoretical saturation was reached after eight interviews. The interviews were audio-recorded and transcribed verbatim. Classical grounded theory was used to inductively analyse data by constant comparative analysis. RESULTS: The core category was identified as; 'the clinical eye', clinicians noticing behaviours possibly due to dental anxiety based on their knowledge, experiences, or intuition. The core category comprises the five categories: Sympathetic activation, Patient-reported anxiety, Controlling behaviours, Avoidance and Accomplishment. Initially there is usually uncertainty about whether a behaviour is due to dental anxiety or part of a patient's normal behaviour. To gain additional certainty, clinicians need to recognise a stressor as something in the dental setting by observing a change in behaviour, for better or for worse, in the anticipation, presence or removal of the stressor. CONCLUSIONS: Clinicians identify patients as dentally anxious if their behaviour changes with exposure to a stressor.

RESUMEN

Background: Increased consumption of ultra-processed foods and drinks high in unhealthy fats, salt and sugar is a major driver behind rising non-communicable disease rates in Asia-Pacific. Urban residence is considered a risk factor for increased consumption of these products; yet, evidence on consumption behaviours and drivers from urban populations in the region remains limited. Aim: To understand perceptions and drivers of unhealthy fats, salt and sugar foods and drinks consumption and eating out behaviours in Yogyakarta city, Indonesia. Methods: In-depth qualitative data were collected through open-ended interviews and prolonged interactions in the local food environment, from a purposeful sample (N = 45) equally distributed across three urban communities. Data were analysed according to the principles of content analysis and following an iterative approach. Results: Despite showing high nutritional health awareness, respondents and their household members consumed ultra-processed foods high in unhealthy fats, salt and sugar regularly. Home consumption of these products was based primarily on economic considerations and convenience, but also related to attending requests from other family members, individual preferences and tastes, and social functions. Similarly, despite a reported preference for home-cooked traditional foods, several participants or their family members would frequently eat ready-made meals away from home, due to conflicting school or work commitments. Discussion: Results suggest that public health interventions focused on nutrition education among Indonesian communities should be coupled with measures addressing urban food environment characteristics that promote the consumption of unhealthy diets, be tailored to specific age groups, and leverage traditional food cultures.

RESUMEN

AIM: To understand patients' perceptions and experiences of directly observed therapy (DOT) for tuberculosis treatment in the UK. METHOD: Patients receiving DOT as part of their TB treatment participated in semi-structured and audio-recorded interviews. Data were analysed using a framework approach. RESULTS: Non-adherence was driven by socio-cultural, mental health, employment and discrimination factors. Patients valued DOT for its support and social connection but those in employment feared it could lead to disclosure and social discredit. CONCLUSION: TB patients experience social isolation and fear discrimination. DOT offers a degree of social connection and support for marginalised patients but fails to tackle fundamental barriers to adherence such as mental health issues, addictions, housing and discrimination. Practice implications: Flexible patient-centred methods of DOT should be offered throughout patients' treatment. Research into multi-agency responsibility for promoting adherence needs to be commissioned, implemented and evaluated. Telemedicine and nurse-led clinics may improve access to care and improve patient experience.

RESUMEN

BACKGROUND: Patients who deteriorate in hospital wards without appropriate recognition and/or response are at risk of increased morbidity and mortality. Track-and-trigger tools have been implemented internationally prompting healthcare practitioners (typically nursing staff) to recognise physiological changes (e.g. changes in blood pressure, heart rate) consistent with patient deterioration, and then to contact a practitioner with expertise in management of acute/critical illness. Despite some evidence these tools improve patient outcomes, their translation into clinical practice is inconsistent internationally. To drive greater guideline adherence in the use of the National Early Warning Score tool (a track-and-trigger tool used widely in the United Kingdom and parts of Europe), a theoretically informed implementation intervention was developed (targeting nursing staff) using the Theoretical Domains Framework (TDF) version 2 and a taxonomy of Behaviour Change Techniques (BCTs). METHODS: A three-stage process was followed: 1. TDF domains representing important barriers and enablers to target behaviours derived from earlier published empirical work were mapped to appropriate BCTs; 2. BCTs were shortlisted using consensus approaches within the research team; 3. shortlisted BCTs were presented to relevant stakeholders in two online group discussions where nominal group techniques were applied. Nominal group participants were healthcare leaders, senior clinicians, and ward-based nursing staff. Stakeholders individually generated concrete strategies for operationalising shortlisted BCTs ('applications') and privately ranked them according to acceptability and feasibility. Ranking data were used to drive decision-making about intervention content. RESULTS: Fifty BCTs (mapped in stage 1) were shortlisted to 14 (stage 2) and presented to stakeholders in nominal groups (stage 3) alongside example applications. Informed by ranking data from nominal groups, the intervention was populated with 12 BCTs that will be delivered face-to-face, to individuals and groups of nursing staff, through 18 applications. CONCLUSIONS: A description of a theory-based behaviour change intervention is reported, populated with BCTs and applications generated and/or prioritised by stakeholders using replicable consensus methods. The feasibility of the proposed intervention should be tested in a clinical setting and the content of the intervention elaborated further to permit replication and evaluation.

RESUMEN

Background: Eye movement abnormality in schizophrenia has been studied for several decades. However, patient differences in eye movements across phases of schizophrenia from eye-tracking studies have not been well documented. Aims: This pilot study used eye-tracking technology to investigate attentive bias towards interpersonal communication information across different clinical phases of schizophrenia. Methods: This study included 78 persons at clinical high risk (CHR) for schizophrenia, 68 first-episode (FEZ) patients, and 39 chronically ill patients from the Shanghai At Risk for Psychosis Extending Project (SHARP Extending cohort) as well as 74 healthy controls (HCs). The experiment was an unguided-viewing task composed of 24 trials showing three types of pictures which varied in the degree of interpersonal communication. Type 1 was a scenery picture without people, type 2 was a picture with four people not communicating, and type 3 was a picture with four people communicating. We used two measures: (1) initial fixation duration and (2) total fixation duration. Results: A ratio for both measures was calculated between measures for pictures with more or less interpersonal communication. The ratio of initial fixation duration for pictures with people communicating versus pictures with people not communicating was lowest in chronically ill patients (0.13 (0.34))compared with HCs (0.31 (0.36)), FEZ patients (0.31 (0.46)), and CHR patients (0.36 (0.42)). The difference in the ratios of initial fixation duration for type 2 and type 3 pictures was also significant for female participants (HCs vs chronically ill patients, t=2.706, p=0.009; CHR patients vs chronically ill patients, t=4.079, p<0.001). In addition, the ratio of initial fixation duration on pictures with people not communicating versus pictures without people negatively correlated with participants' high-risk symptoms (r=-0.35, p=0.002) among the CHR group and also correlated with the negative symptom subscore on the Positive and Negative Syndrome Scale (PANSS) among chronically ill patients (r=-0.33, p=0.037). The ratio of initial fixation duration between type 1 and type 3 pictures was associated with PANSS negative symptoms only in female patients with schizophrenia (r=-0.46, p=0.004). Conclusions: These findings suggest an altered attentive bias towards pictures with a high degree of interpersonal communication information across different clinical phases in schizophrenia. The ratio of initial attentive orienting was associated with negative symptoms in female patients.

RESUMEN

Background: Vaccination against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the most desired solution to combat COVID-19. We examined the willingness to accept the vaccine and reasons for vaccine hesitancy, and identified some factors associated with the vaccine hesitancy among the socio-economically disadvantaged urban population from Delhi, India. Methods: We conducted a cross-sectional survey of a randomly selected sample of 1539 households from 31 urban clusters. Data on socio-demographics, health beliefs, and willingness to accept the SARS-CoV-2 vaccine were collected through a face-to-face interviewer-administered, pre-tested questionnaire from an adult member. Vaccine acceptance/hesitancy was analysed by various socio-demographic and health belief variables. Multinomial regressions were carried out to identify the factors associated with the vaccine hesitancy. Results: Overall, 64.9% (95% CI: 62.5 to 67.3) of the respondents would accept the vaccine, 17.4% (95% CI: 15.6 to 19.4) were undecided, and 17.7% (95% CI: 15.8 to 19.7) would not accept the vaccine. The reasons for not accepting the vaccine were: belief that they had immunity (12.9%), the corona was a hoax (11.8%), the vaccine was not necessary (7.4%), and did not want to disturb the natural bodily systems by the vaccine (5.6%). The undecided group mainly would like to wait and see (37.7%), decide when the vaccine become available (11.6%), will take if everyone in their community takes (10.4%). Multinomial logistic regression identified older age, low perceived susceptibility of contracting COVID-19, low perceived severity of COVID-19, low self-efficacy to protect against COVID-19, and unawareness and non-use of Arogyasetu App as significant predictors of vaccine hesitancy. Conclusions: Two-thirds of Delhi's low-income groups would accept the vaccine against SARS-CoV-2. Vaccine hesitancy was associated with older age, low perceived susceptibility, low perceived severity, and low self-efficacy to protect themselves from COVID-19. Hence, efforts are needed to address these issues and vaccine concerns to increase the vaccine uptake.

RESUMEN

AIM: This systematic review aimed to describe behaviour change theories and techniques used to inform nutrition interventions for adults undergoing bariatric surgery. METHODS: A systematic search was conducted across PubMed, PsycInfo, CENTRAL, EMBASE and CINAHL from inception until 09 March 2021. Eligible studies were randomised controlled trials involving nutrition interventions performed by a healthcare provider, to adults that were waitlisted or had undergone bariatric surgery and received a nutrition intervention explicitly informed by one or more behaviour change theories or behaviour change techniques. Screening was conducted independently by two authors. Behaviour change techniques were examined using the behaviour change technique taxonomy version one which includes 93 hierarchical techniques clustered into 16 groups. Quality of included studies was assessed using Cochrane risk of bias 2.0. RESULTS: Twenty-one publications were included, involving 15 studies and 14 interventions, with 1495 participants. Bias was low or had some concerns. Two interventions reported using behaviour change theories (transtheoretical model and self-determination theory). Thirteen behaviour change technique taxonomy groupings and 29 techniques were reported across 14 interventions. Common techniques included '1.2 Problem solving' (n = 9 studies), '3.1 Social support (unspecified)' (n = 9 studies), '1.1 Goal setting (behaviour)' (n = 6 studies) and '2.3 Self-monitoring of behaviour' (n =- 6 studies). CONCLUSION: While behaviour change techniques have been included, behaviour change theory is not consistently reported and/or adopted to inform nutrition interventions for adults undergoing bariatric surgery. Integrating behaviour change theory and techniques in nutrition interventions is important for researchers and bariatric surgery teams, including dietitians, to effectively target behaviours for this population.

RESUMEN

Due to the spread of COVID-19, a key challenge was to reduce potential staff shortages in the healthcare sector. Besides recruiting retired healthcare workers, medical students were considered to support this task. Commitment of medical students in Germany during the COVID-19 pandemic was evaluated using an online survey, with particular focus on their burdens and anxieties. This survey was distributed to students within a 2-week period in April and May 2020. Ultimately, 1241 participants were included in the analysis. During the pandemic, 67.9% (65.3% to 70.5%) of the participants reported that they had volunteered. Furthermore, 88.9% (86.9% to 90.5%) stated that they were against compulsory recruitment in this context. Students who volunteered (committed students) had a significantly lower anxiety index than non-committed students. Additionally, students were more concerned about infecting other patients and relatives than themselves. Higher levels of anxiety were related to lower levels of commitment. A mandatory assignment during the pandemic was rejected by the students and does not seem to be necessary due to the large number of volunteers.

RESUMEN

BACKGROUND: Diabetes distress, self-efficacy and health literacy are associated with diabetes self-management and health outcomes. Measures of coping styles and their impact on diabetes self-management and diabetes-related distress might add value in identifying those at risk of poorer health outcomes. Current evidence of associations between psychological flexibility/inflexibility and diabetes-related health outcomes is limited. AIMS: To measure associations of psychological flexibility, self-efficacy and health literacy with diabetes distress and glycated haemoglobin (HbA1c) in adults with type 1 diabetes. METHODS: We surveyed 105 adults with type 1 diabetes attending a tertiary diabetes outpatient clinic (mean age 27 ± 7.1 years; 53% men; duration of diabetes 12.6 ± 8.5 years; HbA1c 72 ± 22 mmol/mol, 8.7 ± 2.0%; 34% using insulin pumps). We assessed psychological flexibility, self-efficacy, health literacy and diabetes distress. Regression models explored the relative contributions of different factors to diabetes distress and HbA1c. RESULTS: The majority of health literacy scores were in the low-risk range. Those with greater psychological flexibility had higher self-efficacy (r = 0.34; P < 0.01) and reported less diabetes distress (r = -0.54; P < 0.001). In multiple regression analyses, psychological flexibility and self-efficacy accounted for 36% of the variance in distress score (P < 0.001). Shorter duration of diabetes (P < 0.001) and greater psychological flexibility (P < 0.01) correlated with lower HbA1c. A 10-point (one standard deviation) higher psychological flexibility score corresponded to a 0.5% lower HbA1c. CONCLUSIONS: Greater psychological flexibility was associated with less diabetes distress and lower HbA1c. The psychological flexibility construct might inform alternative interventional approaches aiming to improve well-being and glycaemic control.

RESUMEN

Performance on an emotional stop-signal task designed to assess emotional response inhibition has been associated with Negative Urgency and psychopathology, particularly self-injurious behaviors. Indeed, difficulty inhibiting prepotent negative responses to aversive stimuli on the emotional stop-signal task (i.e. poor negative emotional response inhibition) partially explains the association between Negative Urgency and non-suicidal self-injury. Here, we combine existing data sets from clinical (hospitalised psychiatric inpatients) and non-clinical (community/student participants) samples aged 18-65 years (N = 450) to examine the psychometric properties of this behavioural task and evaluate hypotheses that emotional stop-signal task metrics relate to distinct impulsive traits among participants who also completed the UPPS-P (n = 223). We specifically predicted associations between worse negative emotional response inhibition (i.e. commission errors during stop-signal trials representing negative reactions to unpleasant images) and Negative Urgency, whereas commission errors to positive stimuli - reflecting worse positive emotional response inhibition - would relate to Positive Urgency. Results support the emotional stop-signal task's convergent and discriminant validity: as hypothesised, poor negative emotional response inhibition was specifically associated with Negative Urgency and no other impulsive traits on the UPPS-P. However, we did not find the hypothesised association between positive emotional response inhibition and Positive Urgency. Correlations between emotional stop-signal task performance and self-report measures were the modest, similar to other behavioural tasks. Participants who completed the emotional stop-signal task twice (n = 61) additionally provide preliminary evidence for test-retest reliability. Together, findings suggest adequate reliability and validity of the emotional stop-signal task to derive candidate behavioural markers of neurocognitive functioning associated with Negative Urgency and psychopathology.

RESUMEN

This paper describes how to ethically conduct research with Black populations at the intersection of COVID-19 and the Black Lives Matter movement. We highlight the issues of historical mistrust in the USA and how this may impact Black populations' participation in COVID-19 vaccination trials. We provide recommendations for researchers to ethically engage Black populations in research considering the current context. Our recommendations include understanding the impact of ongoing trauma, acknowledging historical context, ensuring diverse research teams and engaging in open and honest conversations with Black populations to better address their needs. The core of our recommendation is recognising the impact of trauma in our research and health care practices.

RESUMEN

The aim of this article is to question the epistemic presuppositions of applying behavioural science in public policymaking. Philosophers of science who have examined the recent applications of the behavioural sciences to policy have contributed to discussions on causation, evidence, and randomised controlled trials. These have focused on epistemological and methodological questions about the reliability of scientific evidence and the conditions under which we can predict that a policy informed by behavioural research will achieve the policymakers' goals. This paper argues that the philosophical work of Helen Longino can also help us to have a better and fuller understanding of the knowledge which the behavioural sciences provide. The paper advances an analysis of the knowledge claims that are made in the context of policy applications of behavioural science and compares them with the behavioural research on which they are based. This allows us to show that behavioural policy and the debates accompanying it are based on an oversimplified understanding of what knowledge behavioural science actually provides. Recognising this problem is important as arguments that justify reliance on the behavioural sciences in policy typically presume this simplification.

RESUMEN

After the Ebola outbreaks the world is again facing a challenge in which human behaviours and contact history play crucial roles in determining the trends in disease spreading within and across communities. With the onset of the recent coronavirus disease (COVID-19) pandemic, several issues related to conducting social behavioural sciences research and related community engagement activities arise, especially in rural areas of low-income countries, where the coverage of information and communication technologies (ICTs) is limited and their application on field-based research would imply a biased selection of relatively more privileged minorities with access to on-line and other communication platforms not requiring physical contact. This article enumerates and discusses the different technical challenges that social behavioural sciences research and community engagement activities face in times of public health emergencies caused by pandemics such as COVID-19. It also highlights the possibility of using alternative approaches to maintain the engagement with members of rural communities in research and social action activities, as well as the ethical challenges arising from such approaches.

RESUMEN

The COVID-19 pandemic has placed an enormous burden on health systems, and guidelines have been developed to help healthcare practitioners when resource shortage imposes the choice on who to treat. However, little is known on the public perception of these guidelines and the underlying moral principles. Here, we assess on a sample of 1033 American citizens' moral views and agreement with proposed guidelines. We find substantial heterogeneity in citizens' moral principles, often not in line with the guidelines recommendations. As the guidelines are likely to directly affect a considerable number of citizens, our results call for policy interventions to inform people on the ethical rationale behind physicians or triage committees decisions to avoid resentment and feelings of unfairness.
