The impact of behaviour problems on caregiver stress in young people with autism spectrum disorders.

Abstract: Background The purpose of this study was to examine the correlates of caregiver stress in a large sample of young people with autism spectrum disorders (ASDs). Two main objectives were to: (  ) disentangle the effects of behaviour problems and level of functioning on caregiver stress; and (  ) measure the stability of behaviour problems and caregiver stress. Methods Parents or teachers of  young people with ASDs completed measures of stress, behaviour problems and social competence. Parents also completed an adaptive behaviour scale. Eighty-one young people were rated twice at a  -year interval. Results Parents and teachers did not perfectly agree on the nature and severity of behaviour problems. However, both sets of ratings indicated that behaviour problems were strongly associated with stress. Conduct problems in particular were significant predictors of stress. Adaptive skills were not significantly associated with caregiver stress. Parental reports of behaviour problems and stress were quite stable over the  -year interval, much more so than teacher reports. Parent ratings suggested that behaviour problems and stress exacerbated each other over time. This transactional model did not fit the teacher data. Conclusion Results of this study suggested that it is a specific group of externalized behaviours that are the most strongly associated with both parent and teacher stress. Results were discussed from methodological and conceptual perspectives.

Pre-school children with and without developmental delay: behaviour problems and parenting stress over time

Abstract: Background Children with intellectual disability are at heightened risk for behaviour problems and diagnosed mental disorder. Methods The present authors studied the early manifestation and continuity of problem behaviours in 205 pre-school children with and without developmental delays. Results Behaviour problems were quite stable over the year from age 36-48 months. Children with developmental delays were rated higher on behaviour problems than their non-delayed peers, and were three times as likely to score in the clinical range. Mothers and fathers showed high agreement in their rating of child problems, especially in the delayed group. Parenting stress was also higher in the delayed group, but was related to the extent of behaviour problems rather than to the child's developmental delay. Conclusion Over time, a transactional model fit the relationship between parenting stress and behaviour problems: high parenting stress contributed to a worsening in child behaviour problems over time, and high child behaviour problems contributed to a worsening in parenting stress. Findings for mothers and fathers were quite similar.

Parenting stress and coping styles in mothers and fathers of pre-school children with autism and Down syndrome.

Abstract: Background The study examined the profile of stress in mothers and fathers of preschool children with autism, Down syndrome and typically developing children. A further aim was to assess the association between parenting stress and coping style. Methods A total of 162 parents were examined using Holroyd's 66-item short form of Questionnaire of Resources and Stress for Families with Chronically Ill or Handicapped Members and the Coping Inventory for Stressful Situations by Endler and Parker. Results and Conclusions The results indicated a higher level of stress in parents of children with autism. Additionally, an interaction effect was revealed between child diagnostic group and parent's gender for two scales of parenting stress: dependency and management and limits of family opportunities. Mothers of children with autism scored higher than fathers in parental stress; no such differences were found in the group of parents of children with Down syndrome and typically developing children. It was also found that parents of children with autism differed from parents of typically developing children in social diversion coping. Emotion-oriented coping was the predictor for parental stress in the samples of parents of children with autism and Down syndrome, and task-oriented coping was the predictor of parental stress in the sample of parents of typically developing children. The results strongly supported earlier findings on parenting stress in parents of children with autism. They also shed interesting light on the relationship between coping styles and parental stress.

Depression in mothers and fathers of children with intellectual disability

Abstract: Parental depression was assessed using the Beck Depression Inventory (BDI) in 216 families with children with autism and/or intellectual disability (ID), and in 214 control families. Mothers with children with autism had higher depression scores (mean = 11.8) than mothers of children with ID without autism (mean = 9.2), who in turn, had higher depression scores than fathers of children with autism (mean = 6.2), fathers of children with ID without autism (mean = 5.0), and control mothers (mean = 5.0) and fathers (mean = 4.1). Forty-five per cent of mothers with children with ID without autism and 50% of mothers with children with autism had elevated depression scores (BDI > 9), compared to 15-21% in the other groups. Single mothers of children with disabilities were found to be more vulnerable to severe depression than mothers living with a partner.

Risk markers associated with challenging behaviours in people with intellectual disabilities: a meta-analytic study.

Abstract: A meta-analysis of prevalence and cohort studies conducted over the last 30 years was carried out to identify risk markers for challenging behaviour shown by individuals with intellectual disabilities (IDs). A total of 86 potential studies was identified from the review, with 22 (25.6%) containing sufficient data to enable a statistical analysis to be conducted. Results indicated that males were significantly more likely to show aggression than females, and that individuals with a severe/profound degree of ID were significantly more likely to show self-injury and stereotypy than individuals with a mild/moderate degree of ID. Individuals with a diagnosis of autism were significantly more likely to show self-injury, aggression and disruption to the environment whilst individuals with deficits in receptive and expressive communication were significantly more likely to show self-injury. In most cases, tests for heterogeneity were statistically significant, as expected. The meta-analysis highlighted the paucity of methodologically robust studies of risk markers for challenging behaviours and the lack of data on incidence, prevalence and chronicity of challenging behaviour in this population.
