Rationale: A large body of work demonstrates the impact of caregiving burden on the well-being of parents of individuals with developmental conditions or mental health problems. However, a relative dearth of research examines this impact longitudinally into parents' older age.

Objective: The current study examines (1) longitudinal changes in the effect of having a child with a developmental or mental health problem on parental negative affect, psychological well-being, and somatic symptoms, (2) age and gender moderations on these effects, and (3) the unique impact of factors related to the child's condition.

The gene on the X chromosome has varying numbers of CGG repeats. The modal number is 30, and expansion to >200 results in fragile X syndrome, but the copy number extends down to 6. Past research suggests that individuals whose CGGs are in the "low zone" (LZ; defined here as ≤ 25 CGGs) may be more environmentally-reactive than those with normal range repeats (26-40 CGGs)-a gene x environment interaction.

Objectives: Parents of individuals with disabilities face ongoing responsibilities of providing care and support for their children, even during the child's adulthood. Past research has shown that this caregiving role is linked to chronic stress and subsequent adverse health outcomes for parents, including impaired cognition. This study examines the impacts of genetic risk for cognitive impairment (apolipoprotein [APOE] ɛ4 allele) among parents of adults with disabilities and comparison parents whose adult children do not have disabilities.

This study examined trajectories of daily living skills, behavior problems, body mass index (BMI), and health conditions spanning nearly a decade in adolescents and adults with fragile X syndrome (N = 134; age range at study end = 19-49 years), examining influences of sex and autism spectrum disorder (ASD) symptoms. Hierarchical linear modeling revealed early increases in daily living skills, with decreases at older ages. Behavior problems became less severe over time, with some increases at older ages.

Parents who have a child with a developmental problem or mental disorder often provide support and assistance to their child throughout their lives, and the burden of caregiving can have an adverse impact on parents' mental and physical health. Using Erikson's theory as a framework, the present study investigated generativity as a moderator of the effects of parenting a child with a disability on parents' well-being during mid- to late life. Using data from the study of Midlife in the United States, we identified 220 parents who had a child with a disability and 3,784 parents whose children did not have a disability.

According to family systems theory, strains from parenting an adult with disabilities may spill over to parents' relationships with their other children and disrupt family dynamics and their well-being in later-life. This study examined whether parental ambivalence toward their nondisabled children is greater in families of adults with disabilities (developmental disabilities [DD] or serious mental illnesses [SMI]) than families without any adult children with disabilities. The study also investigated whether ambivalence mediates the associations between having an adult child with DD or SMI and parents' health.

We examined the benefit of emotional support on daily health in premutation carrier mothers of adolescents and adults with fragile X syndrome ( = 114), and whether this benefit was moderated by the mother's genetic status ( CGG repeat length). In an 8-day daily diary, maternal daily health was assessed subjectively through self-reported number of physical health symptoms and physiologically via cortisol awakening response. Multilevel lagged-day models indicated that premutation carrier mothers with midrange CGG repeats derived less health benefit from a day with high positive emotional support than those with lower or higher numbers of repeats within the premutation range.

The present longitudinal study investigated changes in service receipt and unmet service needs spanning 14 years before and after high school exit in a large community-based sample of individuals with autism spectrum disorder (ASD) (n = 204), of whom 59% had co-occurring intellectual disability (ID). Using multilevel models, potential discontinuity of service patterns at the point of high school exit was examined, as well as the rate of change in services received and needed during the high school years and into the post-high school period. Differences between those with and without ID were probed.

Neuroticism is a stable and heritable personality trait that is strongly linked to depression. Yet, little is known about its association with late life depression, as well as how neuroticism eventuates into depression. This study used data from the Wisconsin Longitudinal Study (WLS; N = 4,877) to examine the direct and indirect effects of neuroticism on late life depression at 3 points in the life course-ages 53, 64, and 71-via stressful life events (i.

Research has shown that individuals with autism spectrum disorder have higher rates of health problems throughout childhood, adolescence, and adulthood, and that this may result in elevated risk of early mortality. This study reported the rate, timing, and causes of death in a large community-based cohort of adolescents and adults with autism spectrum disorder ( = 406) over a 20-year period (1998-2018) and identified predictors of mortality. Over this period, 6.

Objective: Parents of individuals with developmental disorders or mental health problems often provide life-long care and support to their children, which negatively affects their health in part due to chronic stress. This study aimed to examine the experience of stigma as a source of chronic stress among parents of individuals with developmental disorders or mental health problems and the effect of stigma on parental health outcomes.

Method: Using data from the Survey of Midlife in the United States (MIDUS 2 and 3), we constructed a sample for a longitudinal analysis including 128 parents of individuals with developmental disorders (e.

The present study investigated the effects of children without disabilities on maternal physical and mental health in families with adolescents or adults with fragile X syndrome. Mothers with the premutation ( = 87) reported on behavior problems and functional limitations of their adolescent or adult child with fragile X syndrome and their own physical and mental health. Mothers also provided a blood sample to determine CGG repeat length.

Article Synopsis
  • - The study focused on 100 mothers who are carriers of the premutation associated with fragile X syndrome, exploring their health and cognitive characteristics in relation to different CGG repeat patterns in their DNA.
  • - Participants were divided into three groups based on their CGG repeat patterns: non-mosaic premutation, mosaic premutation, and a mix of premutation/full mutation, with the use of machine learning for classification.
  • - Surprisingly, mothers with a small number of full mutation cells (Group 3) reported better overall health and mental functioning compared to other groups, suggesting a potential link between genetic mosaicism and health outcomes.

Very little is known about the health problems experienced by individuals with autism spectrum disorder (ASD) throughout their life course. We retrospectively analyzed diagnostic codes associated with de-identified electronic health records using a machine learning algorithm to characterize diagnostic patterns in decedents with ASD and matched decedent community controls. Participants were 91 decedents with ASD and 6,186 sex and birth year matched decedent community controls who had died since 1979, the majority of whom were middle aged or older adults at the time of their death.

This research examined how parenting adults with developmental disabilities affects parental well-being beyond midlife and into old age. Parents of adults with developmental disabilities ( n = 249) and parents of adults without disabilities ( n = 9,016), studied in their early 50s and mid-60s, were longitudinally tracked into their early 70s. Compared to parents of adults without disabilities, parents of adults with disabilities showed a pattern of normative functioning in their 50s, followed by poorer well-being in their mid-60s, and further declines in health and well-being into the early 70s.

Friendships and social participation are key domains of quality of life for individuals with intellectual disabilities. This study examined the friendships, social and recreational activities, and family social networks of individuals with intellectual disabilities from two distinct diagnostic groups: individuals diagnosed with fragile X syndrome (n = 81) compared with those diagnosed with autistic disorder (n = 226). Within each diagnostic group, individuals in two developmental stages were compared: adolescence and adulthood.

Sustaining community employment is a challenge for adults with autism spectrum disorders, especially for those who have co-occurring intellectual disability, but factors contributing to this employment outcome have not been fully evaluated. This study utilized longitudinal data to explore the impact of contextual influences, family factors, and individual characteristics on sustained employment over approximately 18 months ( N = 105). Very few adults with autism spectrum disorder and intellectual disability achieved sustained employment (14.

Background And Objectives: Parents of sons and daughters with disabilities have ongoing financial burdens and vulnerability due to the demands of caregiving responsibilities and their related direct and indirect costs. This study aims to investigate whether midlife and older parents of individuals with a mental health problem or a developmental disability were particularly vulnerable to the impact of the recession.

Research Design And Methods: The data were drawn from Midlife in the United States (MIDUS), a longitudinal survey of a national probability sample in the United States, Waves II (2004-2006) and III (2013-2014; 84 parents of individuals with a mental health problem, 98 parents of individuals with a developmental disability, and 2,029 parents of individuals without any conditions as a comparison group).

As the number of adults with autism spectrum disorder (ASD) grows, the need to identify modifiable correlates of positive outcomes and quality of life (QoL) gains in importance. Research indicates that perceived stress is significantly correlated with QoL in adults with ASD. Studies in the general population of individuals without disabilities indicate that greater participation in social and recreational activities may lessen the negative impact of perceived stress on well-being, and this association may also hold among adults with ASD.

The present investigation explored long-term relationships of behavioral symptoms of adolescents and adults with developmental disabilities with the mental health of their mothers. Fragile X premutation carrier mothers of an adolescent or adult child with fragile X syndrome (n = 95), and mothers of a grown child with autism (n = 213) were included. Behavioral symptoms at Time 1 were hypothesized to predict maternal depressive symptoms at Time 3 via maternal executive dysfunction at Time 2.

This study aims to extend the definition of quality of life (QoL) for adults with autism spectrum disorder (ASD, n = 180, ages 23-60) by: (1) characterizing the heterogeneity of normative outcomes (employment, independent living, social engagement) and objective QoL (physical health, neighborhood quality, family contact, mental health issues); and (2) identifying predictors of positive normative outcomes and good objective QoL. Findings of an exploratory latent class analysis identified three groups of adults with ASD-Greater Dependence, Good Physical and Mental Health, and Greater Independence. Findings indicate that better daily living skills, better executive function, and more maternal warmth are associated with assignment to better outcome groups.

Background: Research suggests siblings of individuals with schizophrenia are at a heightened risk for depressive symptomatology. Research has not yet examined whether the strains of growing up with a brother or sister with schizophrenia contribute to this risk. This study examined whether early life course burdens associated with an emerging mental illness, and current objective and subjective caregiver burden predicted depressive symptoms in siblings of individuals with schizophrenia.
