Griffith test in the evaluation of phycomotor development in the 1st year of life. A longitudinal study [Il test di Griffith per la valutazione dello sviluppo psicomotorio nel primo anno di vita. Studio longitudinale.]

Griffith psychometric test has been experimented on a group of 20 healthy newborn infants, monitored during their 1st year of life with quarterly check-ups. It was clear that the development general rates were constantly higher than the original values reported by the English author. In particular, in 12 months old infants, the rates appeared significantly higher than the rates observed on the same Italian specimen in past periods. A transverse and longitudinal study of the psychomotor development of subjects included in the specimen has given the opportunity to verify some of his features. The development outlines, traced by employing the average rates relevant to the 5 different aspects monitored (motor, personal-social, language, eye-hand co-ordination, practical reasoning), appeared to be well-balanced, that is without dissynchronisms between the different scales. The only exception being the scale of the social behaviour, were the average rates appear to be sensibly higher at every age. Individual development outlines, on the contrary, appeared to be disjointed in all aspects (except for 4 cases). In the longitudinal analysis then, some noteworthy oscillations in both general and partial rates, were observed among the controls carried out in subsequent periods in all the subjects.
