RESUMO

The diagnosis of cancer interferes in the well-being of the family due to frequent hospitalizations and painful procedures that the child undergoes and can unleash symptoms of stress and anxiety in parents. The investigation of psychosocial factors associated to the experience of childhood cancer has been rendered relevant in front of high cure and survival rates of the child and the use of instruments to evaluate the impact of the child s disease on the life of the parents. Considering the inexistence of instruments with this application in our culture, the present study had as objective the translation and cross-cultural adaptation of the Pediatric Inventory for Parents (PIP) for the Brazilian population, as well as evaluation of reliability, validity and usability. PIP is composed of 42 items distributed in four domains of communication, medical care, emotional function and role function. The items are evaluated as to the event frequency in the last week and the difficulty presented during these events. A 5-point Likert-type summative measurement scale was used, where 1 = none and 5 = very high. Larger scores indicate an elevated level of stress. For the procedures of translation and cross-cultural adaptation, the stages of translation, synthesis, backtranslation, evaluation by expert committee and pretest with 30 parents of children with cancer were followed. For evaluation of internal consistency, Cronbach s alfa coefficient was applied. For evaluation of convergent validity, correlation between the adapted instrument and the state portion of the State-Trait Anxiety Inventory (STAI-S) was made. Usability was verified considering the time needed for filling out the instrument, understanding of the instrument and the form of marking the answers. The final version was named "Pediatric Inventory for Parents - Brazilian version" (PIP-BV) and applied to a sample of 101 parents of children with cancer. The subscales and domains of PIP-BV obtained Cronbach s alfa coefficients equal or superior to 0.70. Spearman s rank correlation coefficient varied from +0.28 to +0.83, indicating positive correlation between PIP-BV and STAI-S. The mean time for filling out the instrument was 27.46 minutes and was considered simple and easy to be filled out. The procedure of cross-cultural adaptation was carried out with success and the psychometric properties of validity, reliability and usability of PIP-BV were satisfactory. Further psychometric evaluations in other populations are recommended.
