Multi-trajectories in different domains of social supports and subjective motoric cognitive risk syndrome: a 16-year group-based multi-trajectory analysis.

OBJECTIVE: The aim of this study was to examine the longitudinal relationships between the trajectories of distinct subtypes of various domains of social supports and risk of subjective motoric cognitive risk (MCR) syndrome. DESIGN: Longitudinal cohort study. SETTING AND PARTICIPANTS: 2,279 participants in the Taiwan Longitudinal Study on Aging (TLSA) between 1999 and 2011. METHOD: A group-based multi-trajectory modeling (GBMTM) was implemented to identify distinct trajectory subtypes within various social support domains, encompassing social networks, emotional support, instrumental support, as well as working and economic status. Logistic regression models were then utilized to evaluate the associations between these trajectory subtypes and the risk of subjective MCR. RESULTS: Among 2,279 participants, GBMTM identified four distinct trajectory subtypes: "low social support" (n = 371), "medium social support " (n = 862), "high social support" (n = 292), and "high social support with employment" (n = 754). The incidence rates of subjective MCR for these groups were 9.4%, 9.0%, 4.1%, and 0.8%, respectively. After adjusting for age, sex, education level, and comorbidities, both "low social support" (adjusted odds ratio (aOR) 4.07, 95% CI [1.60-10.34]) and "medium social support" (aOR 3.10, 95% CI [1.26-7.66]) were significantly associated with an increased risk of subjective MCR compared to the "high social support with employment" group. CONCLUSIONS AND IMPLICATIONS: The current study demonstrates that social support significantly reduces the risk of subjective MCR, with lower support levels correlating to higher risk, necessitating further intervention studies to confirm the link between social support and risk of subjective MCR.

Patient Perspectives on Social and Identity Factors Affecting Multiple Myeloma Care: Barriers and Opportunities.

Patients living with multiple myeloma (MM) have a substantial disease burden and face multiple barriers to care. Building upon our previous research using mixed methods, this focus group research aimed to identify patients' priorities regarding specific social and identity-related needs, map these prioritized needs to the disease journey, and describe patient-generated ideas to improve patient support. Participants noted that patients with MM need a range of emotional, social, and financial support throughout the disease journey. They identified initial MM diagnosis and treatment adherence as two critical points in the MM journey where patients need the most support and assistance. The findings of this research suggest that overall, patients with MM need comprehensive support, ideally from a multidisciplinary team consisting of health care providers, patient advocates, social workers, and psychologists to help patients understand their disease and treatment options, make informed treatment decisions, adhere to treatment, and ultimately reduce their disease burden and improve outcomes. This research revealed that patients with MM need varying types and levels of support, with the most common needs including information on disease and treatment, connections to financial resources and support systems, assistance with navigating insurance options, and transportation and logistical support for medical appointments.

Grounding the Work of Grassroots MCH Leaders in Storytelling.

Our Grassroots Maternal and Child Health (MCH) Initiative works to build the capacity of individuals and organizations in zip codes with persistently high infant mortality rates to bring about systems change that will improve maternal and child health (MCH) outcomes. Foundational to the Initiative is the training and mentoring of local women to become Grassroots MCH Leaders. We greatly honor that these women possess community expertise, essential to the Initiative's success. Our training equips them with strategies they can use to bring about changes in social, economic, political, and/or cultural systems that underlie poor birth outcomes. One impactful strategy they learn is the use of critical narrative intervention (CNI). This approach, grounded in the crafting and sharing of stories, complements statistical, behavioral, and medical approaches to improve MCH outcomes. This article describes the impact of CNI within the Grassroots MCH Initiative. Drawing from 14 Grassroots MCH Leaders' narratives, we present five significant maternal traumas and influential supports in their surrounding contexts. We explore the leaders' reflections on the impact of story development and dissemination. Our findings reveal that situating CNI within the context of a grassroots initiative provides opportunities for leaders to use their stories to advocate for systems change. Personal MCH narratives provide a powerful and respectful approach to public health promotion, as they highlight important systems-level failures that need to be addressed to sustainability improve MCH outcomes.

Quality of life among people living with HIV aged 50 years and over in Australia: Identifying opportunities to support better ageing.

OBJECTIVES: Improved life expectancy has led to an ageing population of people living with HIV in most countries. Research on ageing among people living with HIV has predominantly focused on physical and health-related quality of life rather than multidimensional quality of life. We measured quality of life among older people living with HIV in Australia and identified opportunities to guide the development and implementation of appropriate interventions. METHODS: In a national health and wellbeing survey of Australian people living with HIV, participants aged ≥50 years completed additional questions relevant to ageing. Quality of life was measured using PozQoL, a validated multidimensional instrument assessing quality of life among people living with HIV (range 1-5). Exploratory bivariate analyses aimed to identify sociodemographic characteristics associated with quality of life. Adjusted linear regressions aimed to assess changes in PozQoL score associated with recent experiences (last 12 months) of four exposures: food insecurity, HIV-related stigma, isolation from the HIV community, and difficulties accessing non-HIV health services. RESULTS: Among 319 older people living with HIV, the mean PozQol score was 3.30 (95% confidence interval [CI] 3.20-3.39). In bivariate analyses, PozQol scores were significantly higher among participants who were older (p = 0.006), had higher educational attainment (p = 0.009), were in a relationship (p = 0.005), were employed (p = 0.005), and had a higher income (p = 0.001). In adjusted regression models, PozQoL scores were lower among participants who reported recent experiences of food insecurity (ß -0.49; 95% CI -0.74 to -0.24), stigma (ß -0.53; 95% CI -0.73 to -0.33), isolation from the HIV community (ß -0.49; 95% CI -0.70 to -0.29), and difficulties accessing non-HIV health services (ß -0.50; 95% CI -0.71 to -0.30). CONCLUSIONS: Overall, older people living with HIV in this study had a moderate quality of life. Our findings suggest that HIV services should integrate programmes to support economic security and foster connections within the HIV community and across health services.

Adolescent psychological adjustment and social supports during pandemic-onset remote learning: A national multi-wave daily-diary study.

In spring 2020, U.S. schools universally transitioned to online learning due to the COVID-19 pandemic's onset, thus creating a natural experiment for examining adolescents' risk and resilience during an ongoing school crisis response. This longitudinal study used a daily-diary approach to investigate the role of social support in the link between remote learning and psychological well-being across 64 days among a national sample of adolescents (n = 744; 42% Black, 36% White, 22% Other ethnicity/race; 41% boys; 72% eligible for free/reduced-priced lunch; Mage=14.60, SDage=1.71, age-range = 12-17 years). On days when youth attended remote learning, they reported lower daily positive affect, more daily stress, and higher parent social support. There were no significant differences in the effect of remote learning on affect or stress by race or economic status. On days when youth experienced more parent support, they reported lower daily stress and negative affect and higher daily positive affect. On days when youth experienced more peer support, they reported higher daily positive affect. Overall, the study highlights the impact of pandemic-onset remote learning on adolescents' psychological well-being and emphasizes the need for future research on school crisis contingency planning to address these challenges.

Home quarantine during COVID-19 blunted childhood trauma-related psychiatric symptoms in Chinese college students.

Background: Childhood trauma confers risks to mental health. However, little is known about whether home quarantine (HQ) during the coronavirus disease 2019 (COVID-19) pandemic exaggerated or mitigated the effect of childhood trauma on mental health. Objective: To examine the modulating effects of prior childhood traumas on the longitudinal changes of psychiatric symptoms in college students before and after HQ during the pandemic. Methods: This was a two-wave longitudinal study on the mental health of 2,887 college students before and after HQ during the COVID-19 pandemic. The relationships between the changes in the Patient Health Questionnaire-9 (PHQ-9), Symptom Checklist-90 (SCL-90), 16-item Prodromal Questionnaire (PQ-16), Childhood Trauma Questionnaire (CTQ), and Social Support Rating Scale (SSRS) scores were analyzed. Results: The students with childhood trauma showed a significantly greater decrement in psychiatric symptoms after HQ (F = 17.21, 14.11, 18.87, and 17.42 for PHQ-9, PQ-16 objective and distress, and SCL-90, respectively). The correlation coefficients between the CTQ and these symptoms scales were significant at baseline (r = 0.42, 0.34, 0.37, and 0.39), and decreased after HQ (r = 0.17, 0.20, 0.18, and 0.19). The decrement of depressive, psychotic, and overall symptoms was positively correlated with the scores of the CTQ (r = 0.08-0.27) but negatively correlated with SSRS (r = -0.08--0.14). Multilinear regression analysis confirmed the results of the CTQ and SSRS regarding the modulation of the dynamic changes in psychiatric symptoms. A constructed structural equation model indicated that the total effects of childhood trauma on decreased psychiatric symptoms were partly mediated by lower baseline social support. Conclusion: Home quarantine during the COVID-19 pandemic could blunt the adverse effects of childhood trauma on mental health, especially for prodromal psychotic symptoms in college students. Changes in relative deprivation and social support may be mediating factors.

Eliciting social stressors, supports, and determinants of health through the DSM-5 cultural formulation interview.

Objective: As recognition of the importance of social determinants of mental health has increased, the limitations of clinical competence-enhancing interventions that do not emphasize this approach have emerged. The Cultural Formulation Interview (CFI) is a cultural competence intervention that emerges from a confluence of social medicine and medical anthropology traditions. Limited research has examined how patients respond to CFI questions on social-structural aspects of illness and care to assess whether the CFI adequately elicits information on social determinants of mental health. Methods: Patients' responses during a first intake appointment to three CFI questions on social stressors, supports, or barriers to care from 27 patient-clinician dyads are analyzed through qualitative content analysis. The data come from a hyper-diverse clinical setting in Queens, New York, where no ethnoracial group has a majority and all patient-clinician dyads reflect cross-cultural interactions. Results: At least one social determinant was coded in 89 of all cases, and nearly 44% included themes related to multiple determinants of health. The most-commonly coded theme was social relationships (n = 21), followed by financial instability (n = 7), stigma (n = 5), housing instability (n = 2), and poor access to healthcare, involvement in the criminal justice system, employment instability, area-level poverty, and immigration policies (n = 1 each). Conclusion: Our work shows that social determinants of mental health can be elicited through the CFI. Future work should examine how this information is included in clinicians' formulations and whether the cultural formulation approach would benefit from additional revision to facilitate assessment of socio-structural factors.

Social Support in a Cancer Patient-Informal Caregiver Dyad: A Scoping Review.

Social support that includes promoting healthy behaviours throughout the oncology pathway, from diagnosis to treatment to survival, can leverage existing support networks and improve the health of patients and family members in supportive roles. This scoping review aimed to identify and summarise the impact of social support on the patient-informal caregiver relationship during cancer treatment. Inclusion criteria were related to a high focus on dyadic cancer patient-informal caregiver relationships, considering a population of adult cancer patients in active hospitalisation on an oncology ward, and published between 2012 and 2022 to get a portrait of the literature that might influence the current practice. A systematic search using the "Population, Concept, and Context" framework was performed in PubMed, Web of Science, SCOPUS, EBSCO Medline, and CINAHL: 13 articles from the 16,425 pre-qualified articles published between 2012 and 2022. The narrative synthesis of the included studies highlighted that social support, encompassing its different forms within the context of dyads, is frequently associated with an enhanced quality of life, hope, and resilience of both patients and informal caregivers. However, it is important to recognize that the support interventions provided to patients, particularly caregivers, were frequently not thoroughly evaluated or explained, and the sample sizes of the included studies were often limited. Therefore, this review clarified the social and clinical potential of social support for the patient-informal caregiver relationship, paving the way for future robust studies that require to be powered and designed on specific outcomes to allow informing the practice on specific recommendations.

MAPPING AND IDENTIFYING BARRIERS AND FACILITATORS TO MENTAL HEALTH AND PSYCHOSOCIAL SUPPORT INTERVENTIONS FOR WAR-AFFECTED CHILDREN.

OBJECTIVE: Aim: to map MHPSS interventions for war-affected children, and to identify the barriers and facilitators for interventions target¬ing different layers of the MHPSS pyramid; to assess differences in methodology and study design to give a general outlook for potential future evaluation of interventions. PATIENTS AND METHODS: Materials and methods: A scoping review was conducted by utilising PubMed, Scopus, PsychINFO scientific databases (765 articles were found). In addition to IASC MHPSS intervention pyramid as our framework, we used a combination of inductive and de¬ductive coding to find common themes in facilitators and barriers to the effectiveness of interventions within each layer. To geographically illustrate the locations of war-affected areas and their correlating intervention types, we developed a visual map. CONCLUSION: Conclusions: The phenomenon of unequal distribution of interventions (concentrated in West Asia, North and sub-Saharan Africa, with no interventions (found in literature) in South American or South-East Asia). III-rd level of IASC MHPSS Pyramid "focused, non-specialized supports", received great deal of efforts in MHPSS interventions conducted for children in war-affected areas. Main barriers: increasing trauma-related symptoms; lack of parental or caregiver support impaired successful intervention out¬comes for war-affected children; lack of political will and financial resources, difficulties in priority-setting, or an insufficient health workforce ongoing conflicts. Main facilitators: culturally appropriate design and collaboration with local stakeholders; caregiver involvement in interventions for war-affected children.

Later-life depressive symptoms during the Covid-19 pandemic: Investigations of individual, cumulative, and synergistic effects of social isolation.

OBJECTIVES: This study examines associations between social isolation and depressive symptoms among Hong Kong Chinese adults aged 65 and older by investigating the distinct effects of individual indicators, cumulative index, and typologies of social isolation during the Covid-19 pandemic. METHODS: We used a sample of 260 older adults from a cross-sectional, city-wide online survey targeting 1,109 aged 45+ adults through purposive sampling. Seven indicators of social isolation (not married; living alone; not engaging in social/organizational activities; no social contact with friends or families; lack of family and friends networks; loneliness) using Cornwell & Waite's framework were selected to construct three unique types of social isolation measures. We used latent class analysis (LCA) and regression models to examine the effects of varied typologies of social isolation on depressive symptoms. RESULTS: Individual model of social isolation showed that lack of social contact and feeling lonely were significant predictors of depressive symptoms. A strong linear-trend gradient effect of cumulative social isolation on depressive symptoms was also observed. The LCA model identified four typologies of social isolation (socially isolated; living alone but socially engaged; married but lacking social ties, and not socially isolated); those in the 'socially isolated' and 'married but lacking social ties' groups had the most depressive symptoms. CONCLUSION: Three operationalizations of social isolation demonstrated different utilities and implications in assessing the impacts of social isolation on depressive symptoms. Social contacts and loneliness, rather than living status or other characteristics of isolation, were the factors most strongly associated with depressive symptoms. Support programs should target lonely older adults who lack social engagement opportunities, as they are at increased risk of depression.

A Tale of Two Countries: Changes to Canadian and U.S. Senior Population Projections due to the Pandemic-Implications for Health Care Planning in Canada and Other Western Countries.

To examine COVID-19 mortality demographics to determine if there will be any substantive shifts in population forecasts that will impact health and long-term care planning for seniors in both countries. Demographic data from Statistics Canada and the U.S. Census Bureau to 2060 are adjusted for COVID-19 age-group-specific mortality and then projected forward in five-year increments. These projections are then annualized using a linear imputation between each projected value. Consideration is given to the seniors 65 + , 75 + and 85 + as well as dependency ratios of each age category. Forecasts suggest that the proportion of seniors in the population will roughly plateau in 2035 at approximately 21% (U.S.) and 24% (Canada)-with another uptick observed beginning in 2050 for those aged 75 + . Adjustments due to the pandemic have had little impact on these projections suggesting that-unless there is a major shift in the demographics of pandemic-related mortality-the resource planning implications will be largely inconsequential. Investments in resources to serve seniors need not be done with the intention to repurpose these assets before they are fully depleted. While the demonstrated demographic plateau is likely to hold steady, there is uncertainty around the expected rate of decline in the health of seniors. Depending on this trajectory, community-level social supports could play a large role in lengthening the duration of senior health and independence.

Frontline Service Employees' Profiles: Exploring Individual Differences in Perceptions of and Reactions to Workplace Incivility.

Employee turnover is a big issue in the service industry, which can be significantly affected by job stressors including workplace incivility. This exploratory study aims to identify the frontline service employees' profiles exploring to what extent individuals may have different perceptions of incivility and social supports at work and showing different reactions (job outcomes). In a cross-sectional study, 291 completed questionnaires from a sample of Norwegian frontline service employees were subjected to correlation analysis, K-means clustering, and post hoc ANOVA analysis with Bonferroni correction. Cluster analysis revealed three distinct clusters of employees with different profiles, which indicated that those who perceived the highest level of workplace incivility and the lowest level of social supports at work showed the highest turnover intention compared to that of others. Moreover, employees with longer tenure and the highest perception of social supports at work coped better with workplace incivility and showed the lowest turnover intention.

Needs of care partners of older Veterans with serious illness.

BACKGROUND: The quality of life of care partners and care recipients may be improved by programs that address unmet needs. The aim of this qualitative study was to identify care partners' social and practical needs as they care for Veterans (65 yo+) with serious illness. METHODS: Semi-structured interviews with Veterans with serious illness and care partners of Veterans with serious illness. Interview question domains examined through care partner and Veteran perspectives included: types of support/services currently used, still needed, and anticipated as well as barriers to obtaining those supports/services. Qualitative analyses used an inductive descriptive content approach. RESULTS: Seventeen care partners and 11 Veterans participated. Three main themes emerged from the data: (I) care partners' and Veterans' identified barriers to support (e.g., technology, rurality, awareness of services); (II) care partners' and Veterans' understanding of available supports and services (e.g., misunderstandings regarding VA role and services, heavy reliance on VA, identified sources of support); and (III) care partners' understanding of their caregiving roles (e.g., by tasks and self-identification). CONCLUSION: Results indicate that care partners experience barriers to supporting seriously ill Veterans including awareness, information, and access obstacles that can be addressed to improve access and utilization of available services and supports.

Themes describing social isolation in family caregivers of people living with dementia: A scoping review.

INTRODUCTION: The number of people with dementia has been increasing. Evidence shows that over 16 million family caregivers provide unpaid care for people with dementia. However, family caregivers experience several challenges throughout their caregiving role, including that of social isolation. Although social isolation in people with dementia has been well documented, social isolation in their family caregivers has not received as much scholarly attention. This scoping review sought to address this dearth of research through the following research question: "What are themes, concepts, or constructs that describe social isolation of family caregivers for people living with dementia?". METHOD: An electronic search was conducted in PubMed, PsycInfo, and Scopus, using the following Boolean search phrase: dementia AND "social isolation" AND (caregiver OR carers). Content analysis was conducted to identify relevant themes. FINDINGS: The initial search yielded 301 studies. Through screening processes, 13 studies were eligible for review. Based on a synthesis of evidence, five themes emerged from the data: disease progression, psychological state, social networks, social supports, and technology. DISCUSSION: This review demonstrates that caregiving is related to social isolation in family caregivers of people living with dementia. The experience of social isolation was related to the progression of dementia, psychological states, and lack of supports. In contrast, social supports, social networks, and using technology may reduce social isolation. Identifying themes provides policy and practice implications, such as using information and communication technology to create and redefine social networks.

Young carers and educational engagement: Quantitative analysis of bursary applications in Australia.

Young carers support family members affected by disability or a health condition. The Young Carer Bursary Program aims to support young carers' education. This paper analysed data from consenting bursary applicants (2017-2019) to investigate relationships between wellbeing, educational attendance, home study and other factors. Descriptive statistics, correlation and regression analysis determined significant issues, relationships and influential factors related to young carer (N = 1,443) wellbeing and education. Sixty-eight percent were aged between 13 and 18 years and attended secondary school. One third of the sample reported that they were the main carer in their family and 29% reported receiving no support. Female applicants from single parent households who were the main carer attended educational settings less often. Eighteen percent (n = 267) rated their wellbeing as poor/very poor. Better wellbeing was associated with increased educational attendance (rs  = 0.33, p < 0.001) and home study (rs  = 0.34, p < 0.001). Wellbeing was associated with main carer status, caring for a parent, having a disability, being older and having few supports. Educational attendance was associated with main carer status, higher care load and fewer supports. Home study was associated with having a disability, caring for a sibling, caring for more than 11 hr per week and having fewer supports. Important factors about the age, life situation and challenges experienced by young carers identified in this paper indicate that further research into preferred supports and effectiveness of the bursary in improving educational engagement is warranted.

Relationship between maternal mental status and social supports during pregnancy and until one month after childbirth in a local city.

The aim of this study was to clarify the relationship between maternal mental status and social supports during pregnancy and until one month after childbirth in order to evaluate the actual situation in a local city. A survey was conducted on 78 pregnant women who completed the CES-D (depression score), STAI (anxiety score) and Social Support Scale. Data were collected four times : during the second trimester, the third trimester, postpartum hospitalization, and 1 month after childbirth. The CES-D and STAI scores were initially high during pregnancy and decreased during the postpartum period. The Social Support Scale score, however, was initially low during pregnancy and increased during the postpartum period. The CES-D and STAI scores was significantly and negatively correlated with The Social Support Scale score during all four time periods. Participants ≧ 35 years of age scored lower on The Social Support Scale than did participants < 35 years of age in the second trimester, third trimester, and 1 month after childbirth. These findings should assist with the implementation of a comprehensive support center and may be useful for a local city in Japan. J. Med. Invest. 68 : 265-270, August, 2021.

Self-employment, work and health: A critical narrative review.

BACKGROUND: Self-employment (SE) is a growing precarious and non-standard work arrangement internationally. Economically advanced countries that favor digital labor markets may be promoting the growth of a demographic of self-employed (SE'd) workers who are exposed to particular occupational diseases, sickness, and injury. However, little is known about how SE'd workers are supported when they are unable to work due to illness, injury, and disability. OBJECTIVE: Our objective was to critically review peer-reviewed literature focusing on advanced economies to understand how SE'd workers navigate, experience, or manage their injuries and illness when unable to work. METHODS: Using a critical interpretive lens, a systematic search was conducted of five databases. The search yielded 18 relevant articles, which were critically examined and synthesized. RESULTS: Five major themes emerged from the review: (i) conceptualizing SE; (ii) double-edged sword; (iii) dynamics of illness, injury, and disability; (iv) formal and informal health management support systems; and (v) occupational health services and rehabilitation. CONCLUSION: We find a lack of research distinguishing the work and health needs of different kinds of SE'd workers, taking into consideration class, gender, sector, and gig workers. Many articles noted poor social security system supports. Drawing on a social justice lens, we argue that SE'd workers make significant contributions to economies and are deserving of support from social security systems when ill or injured.

Prevalence and Correlates of Anxiety and Depressive Symptoms in Patients With and Without Multi-Drug Resistant Pulmonary Tuberculosis in China.

China is still among the 30 high-burden tuberculosis (TB) countries in the world and TB remains a public health concern. TB can be a cause of mental illness, with prolonged treatment and several anti-TB drugs leading to extreme mental health problems such as depression and anxiety in TB patients. To investigate the prevalence of anxiety and depressive symptoms among TB patients, and to explore whether drug resistance is a covariate for depressive and anxiety symptoms, a total of 167 pulmonary tuberculosis patients were enrolled in this study, which was conducted from January 1 to September 30, 2020. Data were collected, using a structured questionnaire with a demographic component, the Hospital Anxiety and Depression Scale (HADS), General Health Questionnaire 20 (GHQ-20), the Tuberculosis-related Stigma Scale (TSS) and the Social Support Rating Scale (SSRS). Association between demographics, disease/treatment characteristics, stigma, social support, and anxiety/depression symptoms were investigated either based on Pearson's correlation coefficient or group comparisons based on independent t-test (or Mann-Whitney U-test) Multiple linear stepwise regression analysis was used for determining the predictors of anxiety and depression. The results showed that multi-drug resistance pulmonary tuberculosis patients were associated with anxiety challenges. Multiple linear regression analysis indicated that self-esteem accounted for 33.5 and 38% of the variation in anxiety and depression, respectively. This shows that among tuberculosis patients, self-esteem is the factor that could most explains the depression and anxiety symptoms of patients, suggesting that we may could through improving the environment, society, and family respect and tolerance of tuberculosis patients, thereby improving the mental health of tuberculosis patients.

Marrying into it: Siblings-in-law in the social support networks of adults with intellectual and developmental disabilities.

BACKGROUND: Although attention has been devoted to social supports provided by parents and siblings of adults with intellectual and developmental disabilities (IDD), much less is known about supports provided by the spouses of these siblings-the so-called siblings-in-law. This study examined the role of the sibling-in-law in the social support networks of their brother/sister-in-law with IDD and factors associated with providing greater amounts of tangible, informational and emotional support. METHOD: Siblings-in-law of adults with IDD living predominately in the United States (N = 99) participated in a cross-sectional survey. Measures covered demographic and family background, perspectives towards having a brother/sister-in-law with IDD, supports provided and characteristics of the adult with IDD's social support network. RESULTS: Most siblings-in-law reported providing support to their brother/sister-in-law with IDD. Percentages of siblings-in-law providing support were similar to that of the spouse and the spouse's family in the area of emotional support and similar to percentages of paid professionals in tangible and informational supports. Across all three support types, the main predictor of increased sibling-in-law support levels was a decreased ability of the parents-in-law to care for their child with IDD. Other predictors (e.g. distance from brother/sister-in-law with IDD and disability 'insider' status) varied by support type. CONCLUSIONS: Findings highlight the role of siblings-in-law in the social support networks of adults with IDD, with implications for policy and practice.
