The psychophysiological and health corollaries of child problem behaviours in caregivers of children with autism and ADHD

Feasibility, acceptability, and effects of a web-delivered behavioral parent training intervention for rural parents of children with autism spectrum disorder: A protocol

Caregivers of children with autism spectrum disorder (ASD) often report higher levels of stress and mental health issues. Support services and parent training programs may help buffer the effects of caring for a child with ASD. However, due to the national lack of trained ASD providers and disparity of ASD support resources available in rural areas, caregivers often go without support. A possible solution to reach caregivers in rural areas is web-based interventions. This paper describes an ongoing pilot study examining the feasibility, acceptability, and preliminary effects on caregiver well-being and disruptive child behaviors for a web-based parent training program (Attend Behavior) for caregivers of young children (ages 2-11 years old) with autism spectrum disorder (ASD) living in rural areas (trial registration NCT05554198). The intervention is available on the internet as well as a downloadable app for mobile phones. Participants will be invited to use the intervention program for 12-weeks. Prior to using the program, participants will be asked to take a baseline survey assessing depressive symptoms (PROMIS Depression Short Form-6a), caregiver stress (Parenting Stress Index-Short Form), child disruptive behaviors (Home Situations Questionnaire-ASD and Aberrant Behavior Checklist). After 12-weeks, participants will be asked to complete a post-intervention survey with the same measurement scales plus questions regarding intervention acceptability, appropriateness, and feasibility (Acceptability of Intervention, Intervention Appropriateness Measure, and the Feasibility of Intervention Measure). Participants are also invited to partake in a brief 1:1 interview with a study team member to give further feedback regarding the intervention. Study retention and participant app usage data will be examined. Information generated from this pilot study will be used to inform a future larger scale randomized control trial of Attend Behavior.

Caring by default: experiences of caregivers of children with developmental disabilities in Ghana mirrored in the context of the stress process model

BACKGROUND

Caring for a child with developmental disabilities (DD) is associated with significant stress and burden. Caregivers' experiences are influenced by factors such as poverty, stigma, and the lack of accessibility to services, equipment, and assistive devices. These factors are prevalent in a low-resource setting like Ghana which ultimately influences the experiences of caregivers. The aim of the study was to explore the experiences of caregivers of children with DD in the context of the Stress Process Model.

METHODS

The study employed a descriptive phenomenological design Caregivers of children with DD attending the Neurodevelopmental Clinic of a Teaching Hospital were purposively sampled. Data collection involved semi-structured interviews, reaching saturation with 14 participants. The interviews were audio-recorded transcribed verbatim and analysed using thematic analysis.

RESULTS

Four main themes emerged: perception of caregiving, stressors faced by caregivers, negative health outcomes and coping strategies. Perception of caregiving had two sub-themes as stressful nature of caregiving and time-consuming. Six sub-themes were linked to stressors faced by caregivers: the child's ADL needs, communication barrier, managing challenging behaviour, child's health needs, unmet educational needs, and economic burden. Negative health outcomes had three sub-themes: decline in physical, mental and social well-being. While some caregivers used maladaptive coping strategies like blaming, others employed adaptive coping strategies like religious coping through prayer, self-encouragement and support from other family members.

CONCLUSION

The study highlights the complex interaction between caregivers' perception of their caregiving situation, the stressors they experience, their coping resources,  and the negative health outcomes associated with caregiving. These findings underscore the need for context-specific caregiver programmes to mitigate the negative impacts of caregiving.

A secondary analysis examining the influence of emotional support on the mental health of caregivers of children with autism spectrum disorder

PURPOSE

The study purpose was to examine the effect of emotional support on the overall mental health and stress for caregivers of children with autism spectrum disorder (ASD).

METHODS

A cross-sectional retrospective study using secondary data from the 2016-2019 National Survey of Children's Health was conducted using single variable and multivariable linear regression analyses.

RESULTS

More informal emotional support sources were associated with better overall mental health (β = 0.124, SE = 0.015, p < .001) and reduced stress (β = -0.261, SE = 0.039, p < .001) for caregivers of children with ASD, controlling for covariates. The number of formal emotional support sources was not significantly associated with caregiver overall mental health or stress when controlling for covariates. Increased amounts of total emotional support sources were significantly associated with increased overall mental health (β = 0.042, SE = 0.010, p < .001) and reduced stress (β = -0.093, SE = 0.024, p < .001) for caregivers. Other factors significantly associated with caregiver outcomes included caregiver sex, caregiver marital status, caregiver education level, economic hardship, child sex, child race/ethnicity, ASD severity, and child receipt of ASD treatment.

CONCLUSION

More emotional support sources, in particular informal support sources, may be a protective factor for well-being for caregivers of children with ASD.

PRACTICE IMPLICATIONS

Health care providers should evaluate the impact of their formal support services on caregivers of children with ASD and advocate for increased informal and formal support resources for these caregivers.

Collateral Damage: The Impacts of School Exclusion on the Mental Health of Parents Caring for Autistic Children

Despite legislative and policy mechanisms that promote inclusion in education for children with disabilities, many students still experience exclusion from the education setting. For example, autistic children are more likely than their neurotypical counterparts to be expelled or suspended from school or to refuse to attend school on an ongoing basis. This situation gives rise to various challenges for their parents. This discursive paper synthesizes current knowledge on school exclusion involving autistic children, including the causes and consequences of exclusionary practices. The paper also considers the negative impacts of these exclusionary practices on the emotional and psychological well-being of parents and caregivers. Mental health nurses who understand the issues related to school exclusion can better support the educational, social, and developmental needs of autistic children and the mental health needs of parents or caregivers.

Clinically elevated depression scores do not produce negative attentional biases in caregivers of autistic children

Objective

Depression scores in caregivers of autistic children often fall in the clinical range. The attention of clinically depressed individuals tends to be biased toward negatively toned information. Whether caring for an autistic child might also be characterized by a negative attentional bias was explored here.

Methods

A sample of N = 98 (57 caregivers and 41 controls) completed questionnaires assessing depressive symptoms. Orienting attention to (i.e., vigilance), and shifting attention away from (i.e., disengagement), negative information was assessed via an online version of the emotional face dot probe task.

Results

Mean depression scores in caregivers, falling in the borderline clinical range, were significantly higher compared with controls. Groups, however, were indistinguishable with respect to vigilance and disengagement, and these attentional indices were unrelated to depression scores.

Conclusion

Caring for an autistic child, while associated with borderline clinical depression scores, was not characterized by a negative attentional bias. Findings are discussed in the context of methodological shortcomings and recommendations for future research.

Are all parental experiences equal?: Cluster analysis of salivary cortisol and perception of parental stress in mothers of children with autism spectrum disorder

Many parents of children with autism spectrum disorder (ASD) report high stress levels related to their parenting role. The experience of stress is reflected in physical symptoms and well-being, as observed by abnormal patterns of cortisol regulation. However, it may be a mistake to conceive parenthood as unilaterally stressful as diverse experiences are possible. Mothers of children with ASD provided salivary cortisol samples and self-rated parental stress. The area under the curve with respect to ground was calculated in regard to three daily collection time points. As a group, mothers reported average levels of parenting stress and flat daily cortisol output. The current age of the child and age at the time of diagnosis moderately predicted overall daily cortisol. Hierarchical clusters analysis identified four distinct profiles of stress regulation based on daily cortisol regulation and perception of parental stress. Groups did not differ based on the severity of symptoms related to autism or demographic information. We suggest that other variables, such as stress mediators and secondary stressors, may explain variability in stress regulation. Future research and intervention should perceive the parental experience as heterogeneous and focus on individualizing the support offered in light of diverse experiences.

Co-occurrence of Neurodevelopmental Disorders Predict Caretaker Mental Health in a Latinx Sample

Caretakers to children and adults with neurodevelopmental disorders (NDDs) experience more emotional distress compared to community control samples. Risk factors for poorer mental health among this population include symptom severity and an autism spectrum disorder diagnosis. This study aimed to ascertain a relationship between NDD severity and caretakers' mental health. It was hypothesized that co-occurrence of multiple diagnoses would predict higher anxiety and depressive symptomatology and suicidality. Data was collected from a sample of 93 Latinx caregivers to a child or adult with at least one NDD. Multiple NDDs predicted higher levels of anxiety and depression compared to the symptom severity endorsed by caregivers to those with a single NDD diagnosis, but did not predict increased suicidality endorsement. Because caregivers to those with multiple NDDs are at an elevated risk for depression and anxiety, clinicians should consider screening for internalizing disorders in caregivers when treating individual with an NDD.

Cortisol Reactivity and Observed Parenting among Mothers of Children with and without ADHD

OBJECTIVE

Neurobiological models suggest links between maternal cortisol reactivity and parenting; however, no studies have examined cortisol reactivity and parenting in mothers of school-age children with ADHD.

METHOD

We examined the relationship between observed parenting and maternal cortisol reactivity in two laboratory contexts: the Trier Social Stress Task (TSST) and parenting-child interaction (PCI). Mothers of children with (N = 24) and without (N = 36) ADHD participated.

RESULTS

During the TSST, greater cortisol output and increase were associated with decreased positive and increased negative parenting. However, during the PCI, cortisol output was associated with increased self-reported and observed positive parenting, and decreased observed negative parenting. Cortisol change during the PCI was associated with decreased observed positive parenting and increased self-reported negative parenting. Among mothers of children with ADHD, cortisol output during the PCI was negatively associated with negative, inconsistent parenting. Change in cortisol predicted more inconsistent discipline and corporal punishment.

CONCLUSION

Findings contribute to an integrative biological, psychological, and cognitive process model of parenting in families of children with ADHD.

The Mediating Effect of Parenting Stress on the Relationship Between Social Support and Quality of Life in Parents of Children With Autistic Spectrum Disorder: A Meta-Analytic Structural Equation Modeling

OBJECTIVE

The aim of the present study is to investigate whether parenting stress mediate the relationship between social support and quality of life in parents of children with Autistic Spectrum Disorder. In addition, we examined what other variables moderate the relationships in this mediation model.

METHODS

Using the two-stage meta-analytic structural equation modeling approach (MASEM), 44 correlation matrices were synthesized from 28 empirical studies (N = 13,270) and fitted to the hypothesized mediation model.

RESULTS

There is a significant partial mediation effect of parenting stress on the relationship between social support and quality of life. Subgroup analysis through the first stage analysis suggested that social support measurements, parental role, and child's age moderated the relationship between social support and parenting stress, and that the focus of quality of life moderated the relationship between social support and quality of life. Subgroup analysis through the second stage analysis indicated that parenting stress had a significantly stronger predictive effect on quality of life in Western culture, while the predictive effect of social support on quality of life was significantly stronger in Eastern culture.

CONCLUSION

Having more social support can reduce parents' stress and then improving their quality of life, which can help them cope more positively and effectively with their autistic children.

Caregivers of Children with Autism Spectrum Disorder in Rural Areas: A Literature Review of Mental Health and Social Support

PROBLEM

Caregivers of children with Autism Spectrum Disorder (ASD) report high levels of stress, social isolation, and poor mental health. Social and emotional support may buffer negative effects of stress for caregivers of children with ASD, however, those living in rural areas may be disadvantaged due to social isolation and increased distance from resources. This scoping review examined the literature regarding the mental health and impact of support for rural caregivers of children with ASD.

ELIGIBILITY CRITERIA

Articles were limited to those available in the English language and conducted in a high income country. Articles had to include a population of rural caregivers of children with ASD and focus on caregiver mental health and/or the impact of support on caregiver mental health.

SAMPLE

Searches were conducted with Embase, PubMed, CINAHL, ERIC, and PsycINFO and 22 articles were included.

RESULTS

Study findings indicate overall poor mental health for rural caregivers of children with ASD. Formal and informal support appear to be beneficial in decreasing stress for rural caregivers of children with ASD. However, a few studies indicated that formal support may add stress to rural caregivers.

CONCLUSION

There is limited information regarding support needs and the impact of support services on the mental health of rural caregivers of children with ASD.

IMPLICATIONS

There is a need to increase access to support resources in rural areas for caregivers of children with ASD. Healthcare professionals, including nurses, can play a fundamental role in supporting, educating, and connecting caregivers to other support services.

Diagnostic and Medication Treatment Disparities in African American Children with ADHD: a Literature Review

BACKGROUND

Despite a national focus on achieving health equity, limited attention has been paid to behavioral and pediatric health disparities. As the most common pediatric neurobehavioral disorder, attention-deficit/hyperactivity disorder (ADHD) provides an opportunity to assess the status of pediatric behavior health disparities. The purpose of this literature review is to provide a synthesis of existing research on ADHD diagnostic and treatment disparities between African American and White children.

METHODS

Studies were systematically identified through searches in PubMed, CINAHL, and APA PsycInfo using the terms attention-deficit/hyperactivity disorder, disparity, race, ethnicity, diagnosis, medication, and treatment. Summary calculations were conducted to report the proportions of studies with statistically significant differences in ADHD diagnosis and treatment between White and African American children, and to describe trends in disparities over time.

RESULTS

Forty-one studies were included in this review. The majority of studies identified significant disparities in ADHD diagnosis and medication treatment between African American and White children. While diagnostic disparities show a trend toward reduction over time, a similar trend was not observed in medication treatment disparities. This synthesis provides a critique of the existing literature and recommendations for practice and future research.

Sleep disturbances and physical health problems in caregivers of children with ASD

OBJECTIVES

Caregivers of children with autism spectrum disorder self-report more physical health problems than controls. Sleep disturbances are also more prevalent in caregivers, and are positively associated with physical health problems. The negative impact of caring for a child with ASD on physical health therefore, might occur indirectly via poorer sleep.

METHODS

Participants, of which n = 43 were caregivers and n = 17 were controls, completed self-report measures of physical health problems and, to capture objective measures of sleep, wore an actigraphy device.

RESULTS

Physical health problems were greater in caregivers, as were subjective reports of disturbed sleep. Objectively, waking after sleep onset (WASO) and average number of awakenings were higher, as was sleep latency, and sleep efficiency was poorer, in caregivers. Total sleep time however, was greater in caregivers, as was time in bed. Physical health problems, while unrelated to actigraphy measures, were positively associated with self-reported sleep disturbances. Caregivers' increased risk for physical health problems occurred indirectly via greater self-reports of disturbed sleep.

CONCLUSIONS

Interventions that help alleviate caregivers' sleep disturbances might be effective, by reducing physical health problems, for improving quality of provided care, and this might be explored in future research.

A Virtual Resiliency Intervention for Parents of Children with Autism: A Randomized Pilot Trial

Parents of children with Autism experience high levels of stress. Resiliency is the ability to cope and adapt when faced with stressful events. This randomized, waitlist controlled pilot trial examines the feasibility, acceptability, and preliminary efficacy of an adapted virtual mind-body group intervention for parents of children with ASD. The intervention was feasible and acceptable. The immediate treatment group showed no difference in distress and greater improvement in resiliency and stress reactivity/coping relative to the delayed treatment group, (M difference 5.78; p = .038 and M difference 7.78; p = .001 respectively). Findings showed promising feasibility, acceptability, and preliminary efficacy for parents of children with ASD.

Exploring the Moderating Role of Benefit Finding on the Relationship Between Child Problematic Behaviours and Psychological Distress in Caregivers of Children with ASD

Caregivers of children with ASD often find benefits associated with their caregiving role, and benefit finding predicts lower distress. Child problematic behaviours (CPB), which positively predict caregivers' distress, are perceived to be being less problematic, or more manageable, by caregivers who find benefits. Benefit finding therefore might mitigate the negative psychological impact of CPB. A sample of n = 158 caregivers of children with ASD completed an online survey assessing benefit finding, CPB, and psychological distress. CPB positively, and benefit finding negatively, predicted caregivers' distress. Moderation effects however were not observed. Findings implicate increased CPB and lower benefit finding as risk factors for caregivers' psychological distress. Findings provide clearly definable targets for intervention.

Mental health outcomes among parents of a child who has a developmental disability: Comparing different types of developmental disability

BACKGROUND

There is very little information on the effects of different types of developmental disability on the mental health of parents of children who have a DD.

OBJECTIVE

This paper compared the mental health of parents of children with Autism Spectrum Disorder (ASD), Down syndrome, Fetal Alcohol Syndrome (FAS) and other types of DD.

METHODS

A cross-sectional design was used to examine population-level administrative health data for mental health outcomes in cohorts of fathers and mothers of children with four different types of a DD. As well as type of DD, additional variables were examined, these included: sex of the parent, age of the parent at birth of the child with the DD, income, sex of the child with the DD, number of children in the family and place of residence.

RESULTS

For both fathers and mothers odds of a diagnosis of depression or another mental health problem were associated with type of DD. Parents of children with FAS experienced the greatest odds of a depression or other mental health diagnosis. Odds of a diagnosis for fathers were associated with low income. Odds of a diagnosis for mothers were associated with the sex of the child with the DD.

CONCLUSIONS

These findings are important for understanding families which include a child with a DD, as a guide for future research, and for developing effective programs and services for these parents.

Competition Stress Leads to a Blunting of the Cortisol Awakening Response in Elite Rowers

Background: Anticipation of forthcoming demands is often met with biological up-regulation, for example, levels of the stress hormone cortisol are typically elevated immediately prior to an anticipated event. Similarly, the cortisol awakening response (CAR), a surge in cortisol in the period following waking, is elevated on days of anticipated demand and this is viewed as an adaptive response in the preparation for challenge. This study assessed the effects of competition as an anticipated challenge in elite rowers. Methods: Elite rowers (N = 8) were assessed during two training and two competition weekends. Each assessment involved the measurement of self-reported competitive (cognitive and somatic) anxiety and salivary diurnal cortisol across 2 days representing a preparation day prior to either a training or competition day. Competitive anxiety was measured each morning and saliva samples were provided immediately upon waking and 30 min post waking (CAR) and before bed. Results: Self-reported cognitive and somatic anxiety levels were significantly greater during the competition phase compared with training. Additionally, levels of cognitive anxiety were greater on the day of competition compared with the preparation day. CAR magnitude was significantly reduced during the competition phase compared with training; however, there were no differences between preparation and event days. Conclusions: Reduced or blunted CARs are typically observed in chronically stressed populations and are characteristic of burnout and fatigue. While an increased CAR during competition may represent an adaptive response to challenge, blunted CARs and the concomitant increases in competitive anxiety observed here indicate maladaptive responding during a period where maximized functioning is critical.

Mental Health and Coping in Parents of Children with Autism Spectrum Disorder (ASD) in Singapore: An Examination of Gender Role in Caring

Research has supported the notion that gender plays a significant role in coping and mental health outcome among parents of children with ASD. The current study aims to examine gender role in the relationship between mental health outcome and coping in parents of children with ASD in Singapore. This study involved 97 fathers and 106 mothers of children with ASD completing self-report questionnaires. MANOVA revealed mothers experienced significantly higher stress levels than fathers. Stress was a significant predictor of depression for fathers but not for mothers. Regression analyses found use of active avoidance coping moderated the relationship between stress and depression in both parents. Implications of these findings on intervention are discussed.

Aging and sex affect soluble alpha klotho levels in bonobos and chimpanzees

BACKGROUND

Throughout life, physiological homeostasis is challenged and the capacity to cope with such challenges declines with increasing age. In many species, sex differences exist in life expectancy. Sex-specific differences have been related to extrinsic factors like mate competition and/or intrinsic proximate mechanisms such as hormonal changes. In humans, an intrinsic factor related to aging is soluble alpha klotho (α-Kl). Both sexes show an age-related decline in α-Kl, but throughout life women have higher levels than men of the same age. Sex differences in α-Kl have been linked to a shorter lifespan, as well as to specific morbidity factors such as atherosclerosis and arteries calcifications. In non-human animals, information on α-Kl levels is rare and restricted to experimental work. Our cross-sectional study is the first on α-Kl levels in two long-lived species: bonobos (Pan paniscus) and chimpanzees (Pan troglodytes). As in most mammals, female bonobos and chimpanzees have longer life expectancy than males.

METHODS

We measured serum α-Kl levels of 140 subjects from 16 zoos with an ELISA to examine if α-Kl levels reflect this difference in life expectancy.

RESULTS

In both species and in both sexes, α-Kl levels declined with age suggesting that this marker has potential for aging studies beyond humans. We also found species-specific differences. Adult female bonobos had higher α-Kl levels than males, a difference that corresponds to the pattern found in humans. In chimpanzees, we found the opposite: males had higher α-Kl levels than females.

CONCLUSION

We suggest that contrasting sex differences in adult α-Kl levels mirror the dominance relations between females and males of the two Pan species; and that this might be related to corresponding sex differences in their exposure to stress. In humans, higher cortisol levels were found to be related to lower α-Kl levels. We conclude that there is great potential for studying aging processes in hominoids, and perhaps also in other non-human primates, by measuring α-Kl levels. To better understand the causes for sex differences in this aging marker, consideration of behavioural parameters such as competition and stress exposure will be required as well as other physiological markers.

Lower cortisol response in high-resilient caregivers of people with autism: the role of anger

Caring for an offspring with an autism spectrum disorder (ASD) has been related to high stress levels and health disturbances. However, a protective effect against these negative health outcomes has been described in high-resilient caregivers. In this context, the main aim of the present study was to assess the association between resilient coping and cortisol response to acute stress in caregivers of people with ASD. Furthermore, the study aimed to explore the mediating role of anger in this association. We exposed 40 caregivers of people with ASD to an acute psychosocial stressor in the laboratory. Salivary cortisol samples were obtained before, during, and after the stressor. Resilient coping, anger, and socio-demographic variables were also assessed. Resilient coping was negatively correlated with cortisol response. Specifically, cortisol release was lower in high-resilient than low-resilient caregivers. Anger was positively correlated with cortisol response, mediating the association with resilient coping. The observed associations of resilient coping and anger with cortisol response indicate that these variables may affect health outcomes, resilience being protective and anger harmful. Psychotherapeutic interventions focused on strengthening resilience and anger management could benefit caregivers, improving their health status and quality of life.

Psychosocial functioning and the cortisol awakening response: Meta-analysis, P-curve analysis, and evaluation of the evidential value in existing studies

Cortisol levels rise immediately after awakening and peak approximately 30-45min thereafter. Psychosocial functioning influences this cortisol awakening response (CAR), but there is considerable heterogeneity in the literature. The current study used p-curve and meta-analysis on 709 findings from 212 studies to test the evidential value and estimate effect sizes of four sets of findings: those associating worse psychosocial functioning with higher or lower cortisol increase relative to the waking period (CARi) and to the output of the waking period (AUCw). All four sets of findings demonstrated evidential value. Psychosocial predictors explained 1%-3.6% of variance in CARi and AUCw responses. Based on these effect sizes, cross-sectional studies assessing CAR would need a minimum sample size of 617-783 to detect true effects with 80% power. Depression was linked to higher AUCw and posttraumatic stress to lower AUCw, whereas inconclusive results were obtained for predictor-specific effects on CARi. Suggestions for future CAR research are discussed.

Stress among Parents of Children with and without Autism Spectrum Disorder: A Comparison Involving Physiological Indicators and Parent Self-Reports

Parents of children with Autism Spectrum Disorder (ASD) have been reported as experiencing higher levels of stress and poorer physical health than parents of typically developing children. However, most of the relevant literature has been based on parental self-reports of stress and health. While research on physiological outcomes has grown in recent years, gaps still exist in our understanding of the physiological effects, if any, of stress related to parenting a child with ASD. The present study compared parent-reported stress, anxiety, and depression, as well as selected physiological measures of stress (i.e., cortisol, alpha-amylase, and ambulatory blood pressure and heart rate) between matched groups of parents of children with (N = 38) and without (N = 38) ASD. Participants completed questionnaires, collected saliva samples for the purpose of measuring cortisol and alpha-amylase, and wore an ambulatory blood pressure monitor for 24 h. Parents of children with ASD reported significantly higher levels of parental distress, anxiety, and depression than parents of typically developing children. Parent-reported distress, anxiety, depression, and health were not correlated with physiological measures. With the exception that parents of children with ASD had significantly lower cortisol levels 30 min after waking, no other significant group differences were found for physiological measures. Parents of children with ASD reported significantly higher use of a number of adaptive coping strategies (e.g., emotional support) in comparison to parents of typically developing children. Results are discussed in the context of implications for future research directions, stress research, and practical implications for parental support.

Pilot Study of Parent Psychophysiologic Outcomes in Pediatric Hematopoietic Stem Cell Transplantation

BACKGROUND

Parents of children undergoing hematopoietic stem cell transplantation (HSCT) are at risk for psychological distress. This distress may result in aberrant immune, inflammatory, or endocrine effects. These physiologic outcomes have not been reported previously.

MAIN OBJECTIVE

The aim of this study is to examine the feasibility of longitudinal testing of psychophysiological parameters of stress in parents of children undergoing HSCT.

METHODS

This pilot study was conducted at a large children's hospital in the Midwest and included parents of children who received autologous or allogeneic HSCT. Time points included before the start of HSCT conditioning and day +30, +60, and +100. Outcome variables included parent-perceived stress, lymphocyte subsets, C-reactive protein (CRP), proinflammatory cytokines, salivary cortisol, and salivary amylase. Effect sizes were calculated for each outcome.

RESULTS

Twelve parent-child dyads were enrolled (10 mothers, 2 fathers). Missing data were minimal. Parent-perceived stress significantly increased from pre-HSCT through day +100, and parent CD3+ T-lymphocyte counts decreased from pre-HSCT through day +100. No significant effects were observed for salivary studies, CRP, or proinflammatory cytokines. Effect sizes ranged from 1.23 (perceived stress) to 0.07 (CRP).

CONCLUSION

The results of this study suggest that it is feasible longitudinally measure parent psychophysiologic outcomes in the pediatric HSCT setting. In addition, parent-perceived stress increased linearly from start of conditioning through day +100, whereas parent T-lymphocyte counts decreased concurrently.

IMPLICATIONS FOR PRACTICE

Routine psychological and physical health screening of parents of children undergoing HSCT is needed. Multidisciplinary psychosocial support services should be offered to parents at regular intervals during their child's HSCT.

The psychophysiological impact of childhood autism spectrum disorder on siblings

OBJECTIVE

The negative impact of caring for a child with autism spectrum disorder (ASD) on parents' psychophysiological functioning has been widely evidenced. However, siblings, who also face emotional, social and physical challenges associated with having a brother/sister with ASD, have been less widely studied. This study examined the psychophysiological impact of childhood ASD on siblings.

METHODS

A sample of 25 siblings of children with ASD (and their mothers) and a control group of 20 siblings of neuro-typical children (and their mothers) completed questionnaires assessing: (a) demographic and lifestyle information, (b) family characteristics, (c) child behaviour problems, (d) social support and (e) depressive symptomology. Saliva samples were collected at several time points on two consecutive days, and estimates of the cortisol awakening response (CAR), diurnal cortisol slope and mean diurnal cortisol output were derived.

RESULTS

Total depressive symptoms were higher in siblings of children with ASD compared with controls. Group differences with respect to depressive symptomology were driven more by emotional than functional problems. With respect to physiological functioning, groups were comparable on all cortisol indices. In siblings of children with ASD, social support, especially from parents and close friends, predicted total depressive symptoms, as did the behaviour problems of their brother/sister with ASD.

CONCLUSION

Siblings of children with ASD experience greater emotional problems and overall depressive symptoms compared with a control group. Interventions that enhance social support, as well as helping siblings better understand the behaviour problems of their brother/sister with ASD, might be effective for alleviating depressive symptoms.

Parenting stress, salivary biomarkers, and ambulatory blood pressure: a comparison between mothers and fathers of children with autism spectrum disorders

Parents of children with autism spectrum disorders (ASD) may experience higher levels of stress and health problems than parents of children with typical development. However, most research has focused on mothers, with emphasis on parent-reported stress and wellbeing. This study compared parenting responsibility, distress, anxiety, depression, cortisol, alpha-amylase, and cardiovascular activity between 19 mother-father dyads of children with ASD. Mothers reported higher parenting responsibility, distress, anxiety, and depression than fathers, while fathers had higher blood pressure and heart rate variability. Mothers and fathers had lower than average morning cortisol levels, suggesting stress effects on the hypothalamic-pituitary-adrenal-axis. Parents of children with ASD may benefit from routine health screening (particularly adrenal and cardiovascular function) and referral for stress reduction interventions or supports.
