Parenting-related trauma exposure among parents of children with intellectual and developmental disorders: Development and validation of the Parenting Trauma Checklist.

Parents of children with intellectual and developmental disorders (IDDs) often encounter parenting-related traumatic events. Trauma exposure is a risk factor for mental health problems, including posttraumatic stress disorder (PTSD). Little is known regarding the types of traumatic events that parents commonly experience and how to best assess parenting-related trauma exposure. To address this gap, we developed the Parenting Trauma Checklist (PTC) and tested its psychometric properties. The PTC was created based on an extensive literature review and consultation with stakeholders, which led to the creation of a 17-item instrument. Participants (N = 424) were Canadian parents of children with IDDs who completed an online test battery that included the PTC and several questionnaires to assess PTSD symptoms, global mental and physical health, lifetime trauma exposure, and functional impairment, which were included to test the validity of the new instrument. The PTC demonstrated good construct validity. Ninety four percent of the sample reported parenting-related trauma exposure. Parents reported having experienced an average of 5.79 parenting-related traumatic events, with seeing their child undergo a medical procedure the most frequently endorsed event (68.6%). Experiencing more parenting-related traumatic events was positively associated with higher PTSD symptom levels, r = .35, p < .001. The PTC is a promising instrument that can be used to examine parenting-related trauma exposure. The measure can be used as a screening tool to detect parents' risk of traumatic stress disorders, evaluate traumatic experiences, and assess whether trauma-focused treatment is warranted.
