Longitudinal psychometric evaluation of the developmental disorder parenting stressor index with Japanese parents of children with autism

Abstract

Assessing parenting stress in parents of children with autism has crucial clinical implications because increased parental stress is associated with psychological disorders and personal distress, which can result in worse child–parent relationships. We examined the psychometric properties of a new index for assessing parenting stressors—the Developmental Disorder Parenting Stressor Index and the temporal variability of parenting stressors using longitudinal data of 212 Japanese parents of children with autism aged 2–18 years. The findings indicated that the Developmental Disorder Parenting Stressor Index has appropriate cross-validity, structural validity, construct validity, and reliability. Moreover, the psychometric properties and the brevity of the Developmental Disorder Parenting Stressor Index increase the clinical utility of the scale. The implications of the findings of this study are discussed.

Lay abstract

Parents of children with autism experience high rates of parenting stress. Assessing parenting stress in them has crucial clinical implications because increased parental stress is associated with psychological disorders and personal distress, which can result in worse child–parent relationships. Theorists have proposed that a person’s cognitive appraisal determines whether or not a situation or an encounter is personally stressful. However, prior scales merely measure the outcomes of parental stress as a stress response: little the scales were designed to assess events and cognitive appraisal-related parenting stressors of parents of children with autism. We investigated whether a new index for assessing parenting stressors—the Developmental Disorder Parenting Stressor Index is a valid measure to assess parenting stressors of parents of children with autism using longitudinal online surveys at three times. Participants were 212 Japanese parents of children with autism aged 2–18 years who completed the Developmental Disorder Parenting Stressor Index and measures of autism symptoms and stress response . Overall, the findings indicated that the Developmental Disorder Parenting Stressor Index can be reliably used to measure both experiences and cognitive appraisal of parenting stressors among parents of children with autism. Moreover, the Developmental Disorder Parenting Stressor Index has several advantages and is a valuable measurement tool to be able to evaluate parenting stressors in clinical settings; Developmental Disorder Parenting Stressor Index is shorter, easier to complete, and can evaluate both viewpoints of parenting stressors.
