OBJECTIVE This study examined predictors of excess psychological morbidity in parents of children with intellectual disabilities. METHODS Thirty-two parents of children with intellectual disabilities and 29 parents of typically developing children completed the Hospital Depression and Anxiety Scale, and measures of social support, child problem behaviors, sleep quality, and perceived caregiver burden. RESULTS Parents of children with intellectual disabilities registered high depression and anxiety scores, and the majority met the criteria for possible clinical depression and/or anxiety. The strongest predictor of psychological morbidity was caregiver burden. Analyses of its component dimensions indicated that feelings of guilt held the greatest consequence for depression and anxiety. CONCLUSIONS Caregiver burden, in general, and its guilt component, in particular, predicted symptoms of depression and anxiety in parents of children with intellectual disabilities. Assisting such parents to resolve their feelings of guilt should benefit their psychological status.

In older populations, caregiving for a spouse with dementia has been associated with a poor antibody response to vaccination. The present study examined whether younger caregivers, specifically the parents of children with developmental disabilities, would also show a diminished antibody response to vaccination. At baseline assessment, 30 parents of children with developmental disabilities and 29 parents of typically developing children completed standard measures of depression, perceived stress, social support, caregiver burden, and child problem behaviours. They also provided a blood sample and were then vaccinated with a pneumococcal polysaccharide vaccine. Further blood samples were taken at 1- and 6-month follow-ups. Caregivers mounted a poorer antibody response to vaccination than control parents at both follow-ups. This effect withstood adjustment for a number of possible confounders and appeared to be, at least in part, mediated by child problem behaviours. The negative impact of caregiving on antibody response to vaccination is not restricted to older spousal caregivers, but is also evident in younger parents caring for children with developmental disabilities. The behavioural characteristics of the care recipients may be a key consideration in whether or not immunity is compromised in this context.

BackgroundExaggerated cardiovascular reactions to psychological stress are considered a risk factor for cardiovascular morbidity. Social support may reduce such risk by attenuating cardiovascular reactivity to stress.PurposeTo examine the effects of three independent social support variables and their interaction on cardiovascular reactivity to acute stress. The variables were stranger or friend presence, active supportive or passive presence, and male or female presence.MethodsCardiovascular reactions to mental arithmetic stress were measured in 112 healthy young women tested in one of eight distinct independent conditions: active supportive male friend; active supportive female friend; passive male friend; passive female friend; active supportive male stranger; active supportive female stranger, passive male stranger; and passive female stranger.ResultsSupport from a friend rather than a stranger was associated with attenuated blood pressure reactivity, but only when the supporter was a male friend. Support from a male stranger or female friend was associated with augmented blood pressure reactivity.ConclusionsThis interaction between the intimacy and sex of the supporter on cardiovascular reactivity extends the findings of previous laboratory studies of social support and can, to an extent, be interpreted in terms of the Social Comparison Theory.

Although the chronic stress of caring for a sick/disabled relative has been associated with poorer immunity using a range of outcomes, its impact on secretory immunoglobulin A (S-IgA) in saliva has yet to be examined. Three hypotheses were tested in analyses of data from a large community sample: first, caregivers would have lower S-IgA secretion rates than non-caregivers; second, the impact of caregiving on S-IgA would be particularly apparent in older participants; third, for caregivers, caregiving burden would be negatively associated with S-IgA. The sample comprised three distinct age cohorts, one young (N=623), one middle aged (N=639), and the other elderly (N=582). Participants were classified as caregivers if they regularly cared for somebody other than routine childcare. Caregiving strain was measured and a caregiving burden index was then derived as the composite of the number of people being cared for, the type of care provided, and the residential status of the person being cared for. From 2-min saliva samples, S-IgA secretion rate was measured. There was a significant caregiver status by age cohort interaction; caregivers in the eldest cohort had lower S-IgA secretion rates than their non-caregiving counterparts. Caregiving strain and burden and S-IgA were related, such that caregivers who experienced greater strain and burden had lower S-IgA secretion rates. These findings resonate with those from other studies using different immune outcomes. Considered together, it is clear that that the chronic stress of caregiving has widespread effects on immunity.

OBJECTIVES The origins and persistence of psychological morbidity in caregivers are not fully understood. The present analysis examined the relationship between the strain and burden of caregiving and depression and anxiety in a large community sample. Social support and sleep quality were investigated as potential mediators. DESIGN Cross-sectional and prospective observational study. METHOD Individuals caring for someone other than their own child (N=393) were identified from a population of 2,079. Caregiving strain and burden, social support, and sleep quality were assessed. Participants completed the hospital anxiety and depression scale at the same time and 5 years later. RESULTS Caregiving strain and burden were associated with depression and anxiety symptoms cross-sectionally, and with a worsening of symptoms 5 years later. Sleep quality appeared to mediate the cross-sectional relationships. CONCLUSIONS The demands of caregiving and associated sleep disruption contribute to symptoms of depression and anxiety in caregivers.

Objective: Older spousal caregivers of dementia patients have been found to show a relatively poor antibody response to medical vaccination. In the present case control study in a different caregiving environment, we sought to compare antibody responses to vaccination in parents of children with disabilities and parents of typically developing children. Methods: At baseline assessment, 32 parents of children with developmental disabilities and 29 parents of typically developing children completed standard measures of perceived stress and child problem behaviors. They also provided a blood sample and were then vaccinated with the thymus-dependent trivalent influenza vaccine. Further blood samples were taken at 1- and 6-month follow-ups. Results: Relative to parents of typically developing children (mean titer = 458, standard deviation (SD) = 155.7 at 1 month follow-up and mean titer = 265, SD = 483.0 at 6-month follow-up), caregivers (mean titer = 219, SD = 528.4 at 1-month follow-up and 86, SD = 55.0 at 6-month follow-up) mounted a poorer antibody response than controls to the B/Malaysia strain of the vaccine. Conclusion: The negative impact of caregiving on antibody response to vaccination would not seem to be restricted to older spousal caregivers, but is also evident in younger parents caring for children with developmental disabilities. The behavioral characteristics of the care recipients may be a determinant of whether or not antibody response to vaccination is compromised.

The present study tested whether parents caring for children with developmental disabilities would have higher blood pressure compared to parents of typically developing children (controls). It also examined the psychosocial factors underlying this observation. Thirty-five parents of children with developmental disability and thirty controls completed standard measures of perceived stress, child challenging behaviours and social support and wore an ambulatory blood pressure (BP) monitor throughout the day, for one day. Relative to controls, parents caring for children with developmental disabilities reported poorer psychosocial functioning and had a higher mean systolic BP. Of the psychosocial predictors, only social support was found to be predictive. Moreover, variations in social support accounted for some of the between group differences with the β for parental group attenuated from .42 to .34 in regression analyses. It appears that social support may influence blood pressure responses in parental caregivers. Finally, our findings underscore the importance of providing psychosocial interventions to improve the health of family caregivers.

To date, much of the research linking the stress of caring for children with developmental disabilities (e.g. Autism & Down syndrome) with parental health outcomes have tended to concentrate on mental health with less attention paid to the physical health consequences. Thus, this study sought to explore the psychosocial predictors of poor physical health in these caring parents. One hundred and sixty-seven parents (109 caregivers and 58 control parents) completed measures of stress, child problem behaviours, social support, mastery and physical health. Parents of children with developmental disabilities had poorer physical health compared to control parents. Stress and mastery, but not social support and problem behaviours, were significant predictors of poor physical health within caring parents for children with developmental disabilities. However, the association between mastery and physical health was mediated by perceived stress such that those parents who were higher on mastery reported less stress and better physical health; furthermore, the association between stress and physical health was moderated by social support; those parents high on social support and low in stress had better physical health. These results indicate that the paths between psychosocial factors and poor physical health in the caring parents are working synergistically rather than in isolation. They also underscore the importance of providing multi-component interventions that offer a variety of psychosocial resources to meet the precise needs of the parents.

Epidemiological evidence suggests that poor physical health and depression are highly co-morbid. To date, however, no study has considered whether depression in parents caring for children with developmental disabilities is partly driven by poor physical health. Using data from the Growing Up in Ireland national cohort study (2006 to date), 627 parents of children with developmental disabilities were compared with 7941 parents of typically developing children on scores from the Centre for Epidemiological Depression Scale, chronic health conditions, socio-demographic and child behavioural characteristics. Having a child with disabilities was associated with a higher risk of depression (odds ratio (OR)=1.83, 95% confidence interval (CI): 1.43, 2.35) compared to parents of typically developing children. Adjusting for the presence of chronic health conditions accounted for some of this excess risk (OR=1.77, 95% CI: 1.38, 2.27). The association between having a child with disabilities and increased risk of depression was explained, however, by adjusting for the child problem behaviours (OR=1.07, 95% CI: 0.81, 1.43). This study has confirmed, in a population-based sample, the high risk of depression in parents caring for children with developmental disabilities after adjusting for the presence of a chronic health condition. Importantly, given that poor mental health in these parents is associated with a battery of negative health and social family outcomes, it is imperative that health professionals pay attention to the mental health needs of these parents.

The present study examined the moderating role of social support and challenging behaviour on the stress–physical health relationship in parents caring for children with intellectual disabilities. Parents of children with intellectual disabilities (n = 70) reported more physical health problems compared to control parents (n = 45) and were more likely to visit their general practitioner. Furthermore, challenging behaviours, but not social support, moderated this association: parents of children with intellectual disabilities reported poorer physical health when both challenging behaviours and stress were perceived to be high. These findings suggest that interventions need to be directed towards ameliorating the impact of challenging behaviours.
