Childhood illness-related parenting stress: the pediatric inventory for parents.

OBJECTIVE To develop a measure of parenting stress related to caring for a child with an illness and to evaluate its psychometric properties with a group of parents of children with cancer. METHODS One hundred twenty-six parents (105 mothers, 21 fathers) of children (65 boys and 61 girls, M: age: 12.75 years) being followed by an oncology service were assessed using the 42-item self-report Pediatric Inventory for Parents (PIP). Internal consistency was assessed and construct validity was investigated with standardized, general self-report measures of anxiety and parenting stress. RESULTS Internal consistency reliability for the PIP was high (Cronbach alpha range:80-.96). PIP scores were significantly correlated with a measure of state anxiety and also with parenting stress, demonstrating construct validity. After we controlled for demographic variables and general parenting stress, PIP scores showed strong independent associations with state anxiety. CONCLUSIONS Preliminary data indicate that the PIP is a reliable and valid tool to assess parenting stress in pediatric oncology populations. As a measure of illness-related parenting stress, the PIP may be used to provide information about parent well-being that extends beyond that obtained from general measures.
