BackgroundAdapted parenting support may alleviate the high levels of parenting stress experienced by many parents with intellectual disabilities. MethodsParents with mild intellectual disabilities or borderline intellectual functioning were randomized to experimental (n=43) and control (n=42) conditions. Parents in both groups received care-as-usual. The experimental group also received an adapted version of video-feedback intervention for positive parenting and learning difficulties (VIPP-LD). Measures of parenting stress were obtained pre-test, post-test and 3-month follow-up. ResultsRandomization to the experimental group ledto a steeper decline in parenting stress related to the child compared to the control group (d=0.46). Nostatistically significant effect on stress related tothe parent's own functioning or situation was found. ConclusionsThe results of the study suggest the feasibility of reducing parenting stress in parents with mild intellectual disability (MID) through parenting support, to the possible benefit of their children.
