Background: Identifying what parents describe to be positive about parenting their child who has intellectual disabilities is important for professional practice and how parents can be supported over a lifespan. Methods: Studies in which parents describe the positive aspects of parenting their child with intellectual disabilities were identified via electronic databases searches and analysed in a narrative synthesis. Results: Twenty-two studies were included. Consistent themes emerged relating to positive change, increased personal strength, growth and development largely related to parental intrapersonal orientation. Several studies emphasized that the presence of growth or positive change does not imply the absence of distress. Conclusions: Positive aspects are not consistently defined and measured differently across studies. Consistent themes are described variously attributed to theories relating to coping, adaptation or growth following adversity; however, no single theoretical framework emerged. Factors likely to predict a parent's ability to identify positive aspects are inconclusive.
