Background: There is a lack of studies examining the prevalence and severity of psychosocial distress in parents caring for a child with life-limiting condition. More research is also needed to better understand the experience, support needs and quality-of-life of this population. Aim: To describe the experience and support needs of caring for children with life-limiting conditions and examine the level of distress and quality-of-life experienced by parents. Design: Cross-sectional, prospective, quantitative study guided by an advisory group. Participants completed a survey that included demographics and self-report outcome measures of unmet support needs, appraisal of caregiving, psychological distress and quality-of-life. Bivariate correlation analyses were performed to examine for associations between measures. Setting/participants: Parents currently caring for one or more children (⩽18 years) with a life-limiting condition and registered with a paediatric palliative care service (Australia). Results: In total, 143 parents (88% female) completed the questionnaire (36% RR). Compared with population norms, participants reported low quality-of-life, high carer burden and high psychological distress. Almost half (47%) of the sample met the criteria for one or more diagnoses of clinically elevated stress, anxiety or depression. There were significant associations between the psychosocial outcome variables; carer strain and depression had the strongest correlations with quality-of-life ( r = –.63, p < .001, for both). Participants also reported multiple unmet needs related to emotional and practical support. Conclusions: This study contributes to the growing body of evidence on paediatric palliative care, specifically that parents caring for a child with a life-limiting condition report high levels of distress and burden, low quality-of-life and need more emotional and practical support targeted at their unmet needs. Paediatric palliative care services should routinely assess parent mental health and provide appropriate support.
