[Adaptation of the Multidimensional Trauma Recovery and Resilience (MTRR) questionnaire in a sample of Chilean mothers with a history of child abuse].
OBJECTIVE
Adaptation of the Multidimensional Trauma Recovery and Resilience (MTRR) in a Chilean sample.


METHODS
Participants were 80 mothers drawn from two large metropolitan areas (Santiago and Temuco). Sample participants (in a case control design) were redivided in two groups: 40 mothers identified as physical abusers with history of physical child abuse and 40 mothers identified as nonabusers with history of physical child abuse. Groups were matched on 5 sociodemographic variables. Reliability analysis, item analysis, and group comparisons on the 8 scales of the instrument were performed.


RESULTS
Interrater agreement level was .79 (Kendall's W coefficient) and the internal consistency as measured by Cronbach's alpha coefficient was .75. Twenty-five items (26.3%) significantly discriminated between the groups. Group comparison tests (Wilcoxon Rank-sum Test) also indicated that six of the eight domains discriminated between the groups.


CONCLUSIONS
In our sample, the instrument has reliable results which discriminate between the studied groups. These preliminary findings support future work toward the development of a Chilean version of this instrument.
