Ribas, Seidl de Moura, and Bornstein (2003) administered a Brazilian version of the KIDI (MacPhee, 1981; Ribas, Seidl de Moura, Gomes, & Soares, 2000) and a sociodemographic questionnaire to 64 primiparous mothers of 5-month-old babies living in Rio de Janeiro.
The KIDI was selected for this study because it provides a broad coverage of information.
The KIDI was originally standardized on four groups: college students, mothers, doctoral level psychologists, and pediatricians in the United States (MacPhee, 1981).
Several steps were taken to promote the validity and cultural appropriateness of the Brazilian form of the KIDI and to arrive at a translation that had "adapted" equivalence from a psychological perspective (van de Vijver & Leung, 1997).
In the present study, 11 KIDI items (14, 28, 30, 31, 37, 40, 41, 52, 60, 65, 67) were omitted from the analyses because they did not reach satisfactory discrimination indices in our sample (Anastasi & Urbina, 1997).
Mothers and fathers were asked to complete the KIDI individually.
