While extensive evidence links service use for mental health problems to demographic variables and positive attitudes, studies have not explored the role of transdiagnostic risk factors, like distress intolerance (DI) and repetitive negative thinking (RNT). This study examined the relationship between parental DI and RNT on mental health treatment seeking for parents themselves and their children. Results suggest higher DI and RNT predict service use among parents ( p  < 0.05) but were not significantly associated with help seeking for their children, indicating that factors more proximal to the child may have greater influence when parents make treatment decisions for their children. Results also indicte that DI moderates the relationship between parent psychopathology and parent service use, such that parent psychopathology is significantly associated with service use for those with lower DI, but not at moderate or high levels of DI. Implications for marketing mental health information to parents and engaging them in treatment are discussed.
