Chronic health conditions impact children worldwide. In Australia, Type 1 diabetes (T1D), asthma and eczema are the most common. With young children (5-12 years), parents play an important role in illness care, while also meeting 'worker' and 'parent' roles. However, when doing so, the care they provide to their child is likely compromised, adversely impacting child health and Quality of Life (QoL). Although the experiences of working parents of children with various chronic conditions have been described, those specific to parents of children with the aforementioned types of chronic illness (CI) have not. Nor has an attempt been made to quantify or compare these to those of other parents. Therefore, the primary focus here will be on the well-being of these parents balancing all such demands, with a secondary focus being to compare the challenges of these parents to those all parents (e.g., those of healthy children) face. A review paper followed by three empirical papers are presented. The first study aimed to better understand the demands placed by work, family and carer roles. One-on-one interviews with 15 mothers (M age = 38.20 years; SD = 0.91) revealed that similar to all parents, mothers were impacted in both their work (e.g., missed work opportunities given parent role) and their family (e.g., less time at home given work). However, 'added' carer responsibilities were evident in terms of their work (e.g., taking time off work to care) and family (e.g., less care because of work). These mothers identified physical (e.g., exhaustion), social (e.g., less personal time) and psychological (e.g., overwhelmed) wellbeing as consequences of such demands. Support was identified as key to their ability to cope. These findings helped to inform the second study, which involved the development and validation of a new measure to quantify the 'additional' illness care demands specific to these parents. The Parent Daily Hassles-Chronic Illness (PDH-CI) scale aimed to measure both the 'frequency' and 'hassle' of these demands, using items developed based on past research and parent and expert feedback. An Exploratory Factor Analysis (EFA) using 80 parents (M age = 39.40 years, SD = 5.67) of children with CI revealed that the "Frequency" I acknowledge that copyright of all material contained in my thesis resides with the copyright holder(s) of that material.
