REICHENHEIM, Michael Eduardo and MORAES, Claudia Leite. Psychometric properties of the Portuguese version of the Conflict Tactics Scales: Parent-child Version (CTSPC) used to identify child abuse. Cad. Saúde Pública [online]. 2006, vol.22, n.3, pp.503-515. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2006000300005.
This article follows another, which presented the first phase of the cross-cultural adaptation process examining the psychometric properties of the Conflict Tactics Scales, Parent-child Version (CTSPC), Portuguese version. Fieldwork took place in three public maternity wards in Rio de Janeiro, Brazil, from March to September 2000. Interviews relate to siblings of randomly selected live births. Respondents were mothers. Information on partners was obtained by proxy. Almost all intra-observer reliability kappa estimates were above 0.75. Depending on the scale and type of perpetrator, internal consistency (a) estimates ranged from 0.49 to 0.68. Using the same sample, the iterated principal factor analysis identified four dimensions. Although most items performed well, some failed to adequately load in their expected factors. Construct validity involved exploring the relationship between several other theoretical dimensions and a variable encompassing the cumulative pattern of violence severity. All the hypotheses tested were corroborated. The current evaluation indicates that the CTSPC can be recommended for use in Portuguese-speaking contexts. Still, it also identified some important points needing further investigation and discussion.
