Analisi preliminari di validazione del Lausanne Trilogue Play pre-natale per lo studio delle competenze genitoriali in gravidanza.

Object: the aim of study is to apply the prenatal Lausanne Trilogue Play procedure (LTP; Fivaz-Depeursinge, Corboz-Warnery,1999) in order to investigate the applicability and psychometric characteristics of the coding system (Carneiro et al., 2006) of the procedure. The prenatal Lausanne Trilogue Play is an observational procedure, usefull to assess parents' interactions with a doll, in which pregnant mother and father are in a role-play situation divided in 4 parts. Method: Forty couples from a non-clinical population, expecting their first child, took part and were studied at the 7th month of pregnancy with the prenatal LTP procedure, and compared with a non-clinical sample of 49 couples from a Swiss validation study (Carneiro et al., 2006). Results: the scales and total score of the procedure show good reliability (Prenatal LTP: a=.717) and they correlate with each others. There is no significant differences between Italian and Swiss samples (Carneiro et al., 2006). The data show a high degree of homogeneity in the distribution of the two groups. The only difference is on "Structure of play" : the scale shows no significant correlation with the other scales in the Italian sample. Conclusions: Lausanne Trilogue Play procedure can be adequately applied to the Italian setting, because it mantains good psychometric characterisitcs and enables interaction to be evaluated within the couple and mother-father-infant triad in the pregnancy period.
