Development of clinical prediction rule for diagnosis of autistic spectrum disorder in children.

This study aims to develop a clinical prediction rule for the diagnosis of autistic spectrum disorder (ASD) in children. This population-based study was carried out in children aged 2 to 5 years who were suspected of having ASD. Data regarding demographics, risk factors, histories taken from caregivers and clinical observation of ASD symptoms were recorded before specialists assessed patients using standardized diagnostic tools. The predictors were analyzed by multivariate logistic regression analysis and developed into a predictive model. An ASD diagnosis was rendered in 74.8 per cent of 139 participants. The clinical prediction rule consisted of five predictors, namely, delayed speech for their age, history of rarely making eye contact or looking at faces, history of not showing off toys or favorite things, not following clinician's eye direction and low frequency of social interaction with the clinician or the caregiver. At four or more predictors, sensitivity was 100 per cent for predicting a diagnosis of ASD, with a positive likelihood ratio of 16.62. This practical clinical prediction rule would help general practitioners to initially diagnose ASD in routine clinical practice.

Social interactions in striped hyena inferred from camera trap data: is it more social than previously thought?

Understanding the drivers promoting sociality over solitariness in animal species is imperative for predicting future population trends and informing conservation and management. In this study we investigate the social structure of a desert dwelling population of striped hyena Hyaena hyaena. This species is historically regarded as strictly solitary albeit being the least studied of the extant Hyaenids. Accumulating evidence regarding the frequency of social interactions suggests a revision of striped hyena social structure is required. We hypothesized that striped hyena has a social structure that is more complex than expected for a strictly solitary species. For that end, we deployed an array of camera-traps in a remote desert region in Israel, and compared observed frequencies of striped hyena co-occurrence against null models to test whether hyena co-occurred more than expected by chance. Seven adults were (re)captured by our camera-traps in 49 different instances over 83 tracking days. Of these, 6 exhibited shared space-use around a scarce, isolated perennial water source. Five of them, co-occurred with other hyena (in 3 instances) significantly more frequent than expected by chance (and that timing suggests reproduction is unlikely to be the driving factor). Our findings substantiate evidence of complex social structure in striped hyena, highlight the importance of a scarce resource in space-use and sociality, and provide a baseline for future research of striped hyena social structure. We suggest that similar methods be employed to evaluate social structure in other “solitary species” to better understand their social dynamics.

Evolution of the Individual Attitude in the Risk Decision of Waste Incinerator Construction: Cellular Automaton Model

In current work, the phenomenon of NIMBY (not in my back yard) for a municipal solid waste incinerator was recognized through an investigation for the evolution of individual risk attitude to group risk attitude (ItGRA). The cellular automaton model was employed to evaluate the risk attitude status with different frequencies of social interaction between residents. In the simulation case, the risk attitude of residents in the pseudo-rational state and non-pseudo-rational state was evaluated, which indicates the sheep-flock effect on the exaggeration of public NIMBY attitude. To the incinerator, the individual risk attitude evolved to supportive group risk attitude at a social interaction frequency 100 times higher than that in family or local neighborhoods, when the initial number of residents in opposition and support was equal. This was supported by the result of the model in the evaluation of resident risk attitude around the incinerator in Shanghai. On the contrary, for those in a non-pseudo-rational state, the ultimate group risk attitude depends on the probability that the residents have a supportive or opposing risk attitude as the concept of individuals was difficult to change. Accordingly, the decision strategy of incinerator construction should consider the influence of the sheep-flock effect, which can increase the attitude of residents in support and lead to the evolution of a group risk attitude to support attitude. Therefore, this study provides insight into the evolution of public attitude to NIMBY attitude and a promising evaluation method to quantify and guide the individual and group risk attitudes.

Intraspecific variation in behaviour and ecology in a territorial agamid,

Intraspecific variation as a way to explore factors affecting the evolution of species traits in natural environments is well documented, and also important in the context of preserving biodiversity. In this study, we investigated the extent of behavioural, morphological and ecological variation in the peninsula dragon (Ctenophorus fionni), an endemic Australian agamid that displays extensive variation in colour across three allopatric populations. The aims of the study were to quantify variation across the different populations in terms of the environment, morphometric characteristics and behaviour. We found population level differences in habitat structure and encounter rates. Adult body size of C. fionni, as well as a range of morphometric traits, differed between populations, as well as the frequency of social interactions, which appears to be related to population density and abundance. Analysis of communicative signals showed differences between the southern and central populations, which appear consistent with variations in response to environmental differences between study sites. The findings of the present study, coupled with previous work examining colour variation in this species, show that the three populations of C. fionni have likely undergone substantial differentiation, and would make an interesting study system to explore trait variation in more detail.

Meeting Students Where They Eat: A Qualitative Study Exploring K-12 Student Experiences of the School Cafeteria

Research into school cafeterias has largely focused on the nutritional content of food and what students consume. However, the cafeteria is also an important setting for understanding and promoting the overall well-being of students. Through 17 group interviews with 96 students, we conducted an open-ended exploration of their perspectives on the environment in which they eat. The interviews highlight a variety of stressors present in the cafeteria setting, including crowding, volume, and frequent adverse social interactions. We use the framework of proxemics and the concept of incivilities to reflect on students’ experience of the social and built environment of the cafeteria, suggesting that a more positive lunch experience would offer a better balance of stimulation and privacy for students.

The impact of asthma on children's school life aged 6 to 12 years.

Introduction: Asthma is the most common respiratory disease in children. Asthma symptoms can result in children having frequent school absences limited physical activities and social interactions with peers within the school setting. Purpose: The purpose of this study was to investigate the effect of asthma on children’s school life aged 6-12 year related to demographic characteristic, school absences due to hospitalization, academic performance, physical activity, asthma stigma and school violence. Methods: Data were collected with the use of a questionnaire. Questions regarding the child's demographic information as well as factors that cause children’s asthma attacks, types of treatment followed in the past year, children’ compliance to treatment instructions, children’s duration of absence from school due to hospitalization, children’ academic performance and frequency of participation in sports activities were included. Results: The present descriptive cross-sectional study was conducted at a large pediatric hospital in Western Greece and included 160 parents of children with asthma. Analysis of the questionnaires showed that children were absent from school “less than one week” (48.3%) while child’s academic performance was affected by their condition. Finally, four out of ten children play with their peers during school recess, while 18.4% prefer to play alone. Weather conditions and allergens were reported as the most prevalent (N = 90) factors that caused their child’s asthma attacks. Parents claim their children have experienced some form of school violence while two out of ten parents choose not to talk openly about their child’s health problem. Conclusion: Asthma has an impact on children’s school life. Informative programs for students and teachers may be useful, aiming to raise awareness about asthma, and contribute to integrate these students in the school setting while avoiding difficulties.

Social Interaction in Major Depressive Disorder, Social Phobia, and Controls: the Importance of Affect

Objective: Social interactions are crucial to human beings. As technology advances, new possibilities of interaction emerge, bringing both opportunities and risks, especially when interpersonal behaviors are impaired (e.g., depression) or associated with strong fear (e.g., social phobia). The authors investigated whether technological social interactions (i.e., phone and internet/chat) are used equally as often as face-to-face social interactions in participants with mental disorders and in controls and whether differences are associated with unpleasant emotions, that is, whether the association between negative affect (NA) or positive affect (PA) differed by type of social interaction. Methods: The self-chosen social interactions of participants diagnosed with major depressive disorder (MDD) or social phobia (SP) were compared with participants without these diagnoses (control group, CG). Using event sampling methodology (ESM), participants’ everyday social behavior was sampled six times per day for one week in their natural environment. Findings/Results: The CG engaged more often in face-to-face social interactions, while participants diagnosed with MDD or SP engaged more often in phone social interactions. Across all groups, there was a positive relationship between NA and the frequency of technological social interactions, and a positive relationship between PA and the frequency of face-to-face social interactions. Conclusions: The propensity to experience higher levels of PA during face-to-face social interactions and NA during technological social interactions is important to consider when selecting and planning social interactions. Clinicians may consider exploring the social interaction patterns of their patients in the light of these findings. Likewise, developers of technological interventions and clinicians using them should consider the potential that technological social interactions may increase NA.

Social Behavior of a Reproducing Pair of the Philippine Tarsier (Tarsius syrichta) in Captivity

ABSTRACT Social interactions of the nocturnal primates are not well studied. One of the species for which social behavior is scarcely known is the Philippine tarsier (Tarsius [= Carlito] syrichta). We observed a reproducing pair of captive individuals over two mating seasons for two consecutive years. The tarsiers spent approximately 4% of their activity budget on social interactions; ca. 20% of time in 0–1 m proximity to each other; and shared sleeping sites for half of the study time. The majority of the animals’ social interactions were peaceful: affiliative and sexual (83%), and the smallest component of the behavior was agonistic (17%). We witnessed two copulation events (one per estrus day), each lasting ca. 5 min, and both occurring just after waking. We revealed temporal – nightly and hourly – fluctuations in the frequency of social interactions, in the distances the individuals spent from each other and in the number of vocalizations. The results present the first assessment of the social behavior of the Philippine tarsier, much needed to improve the captive breeding management for this highly sensitive species threatened with extinction.

WHAT DOES MY PERSONALITY SAYS ABOUT MY FRIENDSHIPS IN LATER LIFE?

Personality traits, such as those identified in the Big Five Personality Model (i.e., openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism), may be associated with different aspects of friendship among older adults. Additionally, men and women form and maintain their friendships differently, which may result in gender differences in their friendships. This study examined the relationship between specific personality traits and friendship characteristics, including friendship quantity, frequency of social interactions with friends, positive and negative friendship quality. The study also explored whether gender moderates the relationship between personality traits and friendships in later life. This study used data from 7,250 community-dwelling older adults, aged 65 years and above (M=75.4 years old, SD=6.91), who participated in 2012 and 2014 Leave-Behind Questionnaire of the Health and Retirement Study. Results from the linear regression analysis indicated significant main effects for the different personality traits and friendship quantity, quality and social interaction frequency, but no main effect for gender was found. However, the moderating effect of gender was significant for the relationship between specific personality traits (i.e. openness to experience, agreeableness and extraversion) and social interaction with friends, as well as for positive and negative friendship quality. For example, older women who scored high on openness to experience reported significantly lower social contact frequency with friends (B=-.16, p<.05) and higher negative friendship quality (B=.08, p<.05) than men who scored high on openness to experience. Study results provide insights for understanding better how personality traits and gender play a role in friendships in later life.

I-CONECT PROJECT: CAN SOCIAL INTERACTION IMPROVE COGNITIVE FUNCTIONS AMONG SOCIALLY ISOLATED OLDER ADULTS?

Epidemiological studies have demonstrated that larger social networks or more frequent social interactions may have protective effects against cognitive decline and the incidence of dementia. Therefore, increasing social interaction could be a promising intervention for improving cognitive well-being in socially isolated older adults. We have conducted multiple NIH-funded randomized controlled trials (RCT) over 10 years, examining whether conversational interactions through webcam and internet can improve cognitive functions and enhance cognitive reserve. In this symposium, we will introduce this series of behavioral intervention trials through 4 presentations. First, Dodge will provide background and results of their previous RCT where they showed efficacy of conversational intervention on domain-specific cognitive functions and introduce the ongoing larger project called I-CONECT (https://www.i-conect.org). Second, Lindsey will introduce technological innovations used in the I-CONECT project including development of user-friendly video-chat devices, recording of audio and video data and innovative recruitment efforts. Third, Asgari will share results on how speech utterance and characteristics collected through the project could distinguish those with mild cognitive impairment from those with normal cognition using machine learning modelling approaches. Finally, Cerino and his team will show results of the study which examined whether cognitive improvements through conversation-based intervention depend on an individual’s personality, laying the groundwork for a personalized intervention trial in the future. The symposium is of interest for those who study social isolation and its prevention, the link among cognition, social isolation and personality, as well as those who focus on technology as a tool for improving well-being of older adults.

IT’S THE LITTLE THINGS THAT COUNT: IMPLICATIONS OF DAILY EXPERIENCES FOR WELL-BEING AND BIOLOGICAL INDICATORS

Middle-age and older adults vary widely in their physical health. This symposium describes studies that identify diverse daily experiences that account variation in health using multiple indicators of well-being (self-reported, biological). Fingerman et al. assessed daily TV viewing among older adults and found that more frequent television watching was associated with poorer physical health, worse health behaviors, and less energy expenditure (via actical watch). Leger et al., examined links between daily affect and sleep. Greater variability in daily positive affect is associated with fewer hours of sleep and greater morning tiredness even after adjusting for mean levels of affect. Luong et al. examined links between daily stress and affect. Interpersonal stressors were associated with greater affect reactivity than non-interpersonal stressors and links were reduced among older adults. Birditt et al. assessed links between daily social interactions and cardiovascular reactivity. More frequent social interactions and negative social interactions were associated with increased heart rate and links varied by gender and race. Polenick et al. examined links between daily social interactions and salivary DHEA-S (a marker of the stress response). Positive interactions predicted greater DHEA-S over the course of the day and links between negative interactions and DHEA-S varied by age group such that younger individuals appeared to be more reactive. These studies offer important clues regarding how daily experiences get under the skin to influence health and well-being.

(OLDER) PEOPLE REMEMBER HOW YOU MAKE THEM FEEL: AGE DIFFERENCES IN THE EFFECTS OF SOCIAL EXCHANGES

Socioemotional Selectivity Theory poses that as we age our motivations transition from knowledge focused to emotionally focused (Carstensen, 1995). This shift to emotional motivation increases the relevance of relationships and social interactions for older adults. We examined different aspects of social support: frequency of positive/negative social interactions, satisfaction with positive social interactions, and bothered by social interactions -- to investigate these effects on one’s global well-being. Negative and positive social exchanges are linked to psychological health (Newsom et al., 2005), however one’s perceptions of those social interactions are important to consider as well -- being satisfied or bothered by social interactions shows a better perspective of the individual’s experience than simply recording frequency. The results of our multi-group path analysis show that there are different effects of social supports on global well-being contingent on age, consistent with socioemotional selectivity theory. For adults under 30 years old (Mage = 24.0, range 18 to 29) social support did not significantly relate to well-being. For adults over 30 and under 50 (Mage = 38.9) frequency of positive social interactions is significantly related to well-being (B = .201). For adults over 50 (Mage = 58.8, range 50 to 87) the perception of social exchanges, not their frequency, are what influence well-being: both satisfaction with positive social interactions (B = .402) and being bothered by negative social interactions predict well-being (B = -.193). It is important to know that older adult’s perceptions of social exchanges effect their well-being, future directions are discussed.

Social capital and job search assistance: A multilevel analysis of East Asian countries

This study analyzes the network antecedents of receiving job search assistance, specifically how and to what extent social capital relates to this process. Data come from probability samples on four East Asian countries. Hierarchical linear models are estimated to investigate the associations between social capital and inequality in the receipt of information and influence from personal contacts during job search. Adjusting for confounders, organizational affiliation, civic participation, and frequency of social interaction significantly predict the rate of assistance. Also significant are network size and diversity. Net of compositional effects, regional-level civic participation is further associated with the outcome. Finally, three significant cross-level interactions are observed with respect to social network characteristics (size and diversity). Understanding why some people receive more job search assistance is fundamental to status attainment and labor market inequality. Findings herein shed new light on this critical, yet underexplored, issue.

Childhood trauma, life-time self-harm, and suicidal behaviour and ideation are associated with polygenic scores for autism

Autistic individuals experience significantly elevated rates of childhood trauma, self-harm and suicidal behaviour and ideation (SSBI). Is this purely the result of negative environmental experiences, or does this interact with genetic predisposition? In this study we investigated if a genetic predisposition for autism is associated with childhood trauma using polygenic scores (PGS) and genetic correlations in the UK Biobank (105,222 < N < 105,638), and tested potential mediators and moderators of the association between autism, childhood trauma and SSBI. Autism PGS were significantly associated with childhood trauma (max R2 = 0.096%, P < 2 × 10−16), self-harm ideation (max R2 = 0.108%, P < 2 × 10−16), and self-harm (max R2 = 0.13%, P < 2 × 10−16). Supporting this, we identified significant genetic correlations between autism and childhood trauma (rg = 0.36 ± 0.05, P = 8.13 × 10−11), self-harm ideation (rg = 0.49 ± 0.05, P = 4.17 × 10−21) and self-harm (rg = 0.48 ± 0.05, P = 4.58 × 10−21), and an over-transmission of PGS for the two SSBI phenotypes from parents to autistic probands. Male sex negatively moderated the effect of autism PGS on childhood trauma (β = −0.023 ± 0.005, P = 6.74 × 10−5). Further, childhood trauma positively moderated the effect of autism PGS on self-harm score (β = 8.37 × 10−3 ± 2.76 × 10−3, P = 2.42 × 10−3) and self-harm ideation (β = 7.47 × 10−3 ± 2.76 × 10−3, P = 6.71 × 10−3). Finally, depressive symptoms, quality and frequency of social interactions, and educational attainment were significant mediators of the effect of autism PGS on SSBI, with the proportion of effect mediated ranging from 0.23 (95% CI: 0.09–0.32) for depression to 0.008 (95% CI: 0.004–0.01) for educational attainment. Our findings identify that a genetic predisposition for autism is associated with adverse life-time outcomes, which represent complex gene-environment interactions, and prioritizes potential mediators and moderators of this shared biology. It is important to identify sources of trauma for autistic individuals in order to reduce their occurrence and impact.

Social Interactions in Zoo-Housed Elephants: Factors Affecting Social Relationships.

Simple SummaryIn the wild, elephants live in large, complex social groups. Herds consist of a mixed structure of related females and their calves. One area of concern regarding the maintenance of zoo elephants has been the inability to provide them with social groupings that reflect wild group structure, and whether this impacts on their welfare. Here, we investigated whether a number of factors at the individual (e.g., personality, age or relatedness to others) and zoo (e.g., herd size, presence of calves in the group) level affected the frequency of social interactions in zoo elephant herds. Interactions were defined as positive or negative and then subdivided into physical and non-physical interactions. Social interactions were found to be related to age, personality, presence of calves in the herd, relatedness to other elephants in the herd and species (African or Asian). Calves engaged in the greatest amount of positive interactions but no extreme aggression was observed between any individuals, which was considered indicative of good social management. Increasing understanding about social structures that are affecting elephant relationships enables targeted management plans to be created, in order to provide elephants with the most appropriate social environments. These findings support the recommendations that elephants should be housed in related herds with multiple ages wherever possible, but they also highlight that unrelated elephants can still form compatible and successful social groups.Elephants have complex social systems that are predominantly driven by ecological factors in situ. Within zoos, elephants are held in relatively static social groups and the factors observed driving social relationships in the wild are largely absent. Little research has investigated the effect of social group factors in zoos on elephant social interactions. The aim of this research was to establish whether there is a relationship between social group factors and social behaviour, in order to identify factors that make elephant herds more or less likely to be compatible. Results will facilitate recommendations for optimum social groupings for zoo elephants. Behavioural data quantifying social interactions were collected between January 2016 and February 2017 at seven UK and Irish zoos and safari parks from 10 African and 22 Asian elephants. Social interactions were split into four categories: positive physical, positive non-physical, negative physical and negative non-physical. Social interactions were related to age (positive physical higher and negative non-physical lower in calves than adults), personality (elephants with higher sociability scores engaged in more positive interactions and less negative interactions), presence of calves in the herd (herds with calves had more positive non-physical), relatedness to other elephants in the herd (positive non-physical were higher when relatives were in the group and negative non-physical were higher between unrelated elephants) and species (Asian elephants engaged in more positive non-physical than African elephants). A greater understanding of factors that may contribute to the success of zoo-elephant social groups is important for individual and herd welfare as it will enable evidence-based decisions which have minimal impact on social structures to be executed. This knowledge will enable proactive management approaches to be undertaken and will thus be paramount in ensuring optimal welfare for elephant herds moving forwards.

Crime Victimization, Place Attachment, and the Moderating Role of Neighborhood Social Ties and Neighboring Behavior

Place attachment is the development of a psychological and emotional bond between an individual and their environmental setting. While positive experiences in the residential neighborhood are central to ongoing develop-ment of people–place bonds, whether negative experiences erode place attachment remains unknown. In this study, we explore the relationship between crime victimization, social ties, neighboring behaviors, and place attachment in Brisbane, Australia. Using multilevel linear modeling, we examine whether negative experiences, specifically crime victimization, in the residential neighborhood affect residents’ attachment to place. We also explore whether this relationship is moderated by neighborhood social ties and/or interactions with neighbors. Results indicate that the negative impact of victimization in the residential neighborhood on place attachment is attenuated through frequent social and/or functional interactions with neighbors.

Alexithymia – Not autism – is associated with frequency of social interactions in adults

ObjectiveWhile much is known about the quality of social behavior among neurotypical individuals and those with autism spectrum disorder (ASD), little work has evaluated quantity of social interactions. This study used ecological momentary assessment (EMA) to quantify in vivo daily patterns of social interaction in adults as a function of demographic and clinical factors. MethodAdults with and without ASD (NASD = 23, NNeurotypical = 52) were trained in an EMA protocol to report their social interactions via smartphone over one week. Participants completed measures of IQ, ASD symptom severity and alexithymia symptom severity. ResultsCyclical multilevel models were used to account for nesting of observations. Results suggest a daily cyclical pattern of social interaction that was robust to ASD and alexithymia symptoms. Adults with ASD did not have fewer social interactions than neurotypical peers; however, severity of alexithymia symptoms predicted fewer social interactions regardless of ASD status. ConclusionsThese findings suggest that alexithymia, not ASD severity, may drive social isolation and highlight the need to reevaluate previously accepted notions regarding differences in social behavior utilizing modern methods.

An agent-based approach to modeling zero energy communities

As zero energy buildings take on an increasingly prominent role in overall efforts to reduce energy consumption, it is necessary to identify effective policies for their design and implementation. However, current zero energy building (ZEB) policies focus mainly on new buildings, primarily through on-site renewable energy generation, such as rooftop photovoltaic (PV) systems. Having a few high performing buildings will have limited impact if the community as a whole is not net zero. A more practical approach to achieve zero energy goals is to extend the zero energy boundaries beyond an individual building and have a group of buildings evaluated together as a community, such that the community in itself becomes a zero-energy community (ZEC). Successful ZEC implementation requires that community members actively participate in renewable energy and energy efficiency programs and collectively support the goal of zero energy. Hence, a consumer-oriented analysis is needed to support effective ZEC design decisions and promotion efforts. This paper describes a conceptual agent-based model for an urban neighborhood in Des Moines, Iowa, to predict household level renewable energy adoption behaviors in presence of multiple options. Specifically, the level of consumer participation before and after introducing a community solar option for the neighborhood is evaluated via experimentation with the model. Simulation results demonstrate that introducing a community solar program increases household level adoption as well as the proportion of community level electricity consumption met through renewable sources. The amount of increase in adoption, however, depends on the choice of design parameters, such as premium that households must pay to participate. The results also show that timeliness of achieving ZEC goals depends upon the frequency of social interactions in the neighborhood, indicating the importance of community events in the successful creation of a ZEC.

Influence of Lifestyle Redesign® on Health, Social Participation, Leisure, and Mobility of Older French-Canadians.

Developed in California to enable community-dwelling older adults to maintain healthy and meaningful activities, Lifestyle Redesign® is a well-known cost-effective preventive occupational therapy intervention. The impact of a newly adapted French version on older French-Canadians was, however, unknown. To explore the influence of Lifestyle Redesign on older French-Canadians' health, social participation, leisure, and mobility. A mixed-methods design included a preexperimental component (questionnaires administered before and after the intervention and 3 and 6 mo postintervention) and an exploratory descriptive qualitative clinical study. Individual semidirected interviews were digitally audiotaped and transcribed, then underwent thematic content analysis using mix extraction grids. Community. Sixteen volunteers (10 women) aged 65-90 yr (mean = 76.4, standard deviation = 7.6), 10 without and 6 with disabilities. Inclusion criteria were age ≥65 yr, normal cognitive functions, residence in a conventional or senior home, and French speaking. French-Canadian 6-mo version of Lifestyle Redesign. Health, social participation, leisure, and mobility were measured using the 36-item Short Form Health Survey, Social Participation Scale, Leisure Profile, and Life-Space Assessment, as well as a semistructured interview guide. The French-Canadian Lifestyle Redesign had a beneficial effect on participants' mental health (p = .02) and interest in leisure (p = .02) and, in those with disabilities, social participation (p = .03) and attitudes toward leisure (p = .04). Participants reported positive effects on their mental health, leisure, mobility, and social participation, including frequency and quality of social interactions, and indicated that having an occupational routine fostered better health. None of the participants reported no effect. The translated and culturally adapted Lifestyle Redesign is a promising occupational therapy intervention for community-dwelling older French-Canadians. This study sheds light on the influence of the French-Canadian version of the intervention not only on older adults' health and social participation but also on their leisure activities and life-space mobility, two important outcomes not addressed in previous Lifestyle Redesign studies. Moreover, this study provides an in-depth understanding of the Lifestyle Redesign experience of French-Canadian older adults with and without disabilities, including participants with significant communication and mobility disabilities.

Community disadvantage, inequalities in adolescent subjective well-being, and local social relations: The role of positive and negative social interactions

Studies identify the existence of inequalities in adolescent subjective well-being (SWB) across levels of community socio-economic disadvantage. One posited explanation is that community disadvantage harms SWB through undermining positive social relations among residents (often termed social capital). However, social relations can be both positive and negative; for example, social interactions between residents can be friendly or unfriendly, or involve being helped or harmed. Little work has explored negative social relations in communities and their impact on SWB. This study therefore examines the role that local negative social relations may play, alongside positive relations, in understanding inequalities in SWB across communities. Data are taken from a nationally representative survey of 16–17-year olds in England in 2015. Applying multilevel models, findings demonstrate that adolescents living in more disadvantaged communities exhibit lower SWB. In line with current theories, part of this association can be accounted for by weaker positive social relations: the results show that while positive local interactions are important for youth SWB (primarily via higher neighbour trust), young people in more disadvantaged communities report fewer local positive social interactions. However, the models also demonstrate that part of the negative association between community disadvantage and SWB is also accounted for by stronger negative social relations: the results show that negative local interactions are harmful for youth SWB (both directly, and indirectly via lower neighbour-trust), and young people in disadvantaged communities report more frequent negative local social interactions. Importantly, the negative indirect-effect of community disadvantage via increasing negative social interactions is almost twice as strong as the negative indirect-effect of disadvantage via reducing positive interactions. Taken together, community disadvantage appears to harm SWB not only by reducing positive relations but also increasing negative relations. These form dual, independent, social relations pathways through which community disadvantage affects SWB.
