Analysis of gain scores, also called change scores or difference scores, was used to test for the effect of treatment; unpaired Student’s t-tests were used to compare the post- and pre-test difference in scores between the control and intervention groups (Allison, 1990; Ragosa, 1995; Oakes and Feldman, 2001). Since baseline differences between groups existed at pre-test, analysis of covariance (ANCOVA) was applied as an alternative to analyze the scores. We used the post-test gross motor and pre-literacy scores as the dependent variable, the control/intervention group as independent variable and the pre-test score as covariate. ANCOVA focuses on differences between the groups at post-test while holding constant pre-test differences. In all the analyses, the level of significance was set at p < 0.05. Statistics were performed by using STATA/MP 12.1.
Abilities
On baseline, CG and you will IG did not reveal people high variations (p > 0.05) in terms of sex, chronological years, pounds, peak, Bmi and you may terrible engine profile, as revealed inside Table 2.
After the experimental period, CG did not exhibit any significant difference in locomotor, object-control skills or QGMD scores. In contrast, the intervention group showed significant differences (p < 0.001) from baseline to post-test in gross motor skills. As shown in Figures 2, 3, locomotor, object-control skills and QGMD increased by 24.4%, 9.7%, and 10.4%, respectively, in IG. Moreover, the mean difference of QGMD between pre- and post-intervention in IG was significantly higher than that in CG (11.3 vs. 3.2, p = 0.0082). These results confirmed preliminary results previously reported (Battaglia et al., 2018). The same result occurred for the locomotor skills, showing a significant mean difference of 2.5 in IG compared to the 0.7 in CG (p = 0.0050). The analysis of covariance confirmed the positive effect of the intervention in the improvement of children's gross motor skills, starting even from different pre-test scores.

Desk step three displays that one items of locomotor and you may target manage experiences don’t rise in the brand new manage category following experimental several months, if you are a very tall improve is actually seen in all the items in the IG in reaction so you’re able to PEP.
Most of the pre-literacy skills significantly increased inside IG pursuing the intervention months, whilst in CG precisely the number of errors towards the naming away from stuff notably reduced (find Desk cuatro). Yet not, this new analyses away from get score and you can ANCOVA failed to let you know one significant impact from the intervention between CG and you can IG.
Dialogue
This study investigated the effects of a specific PEP on the outcomes of fundamental motor and pre-literacy skills concerning visual analysis and spatial orientation abilities in a sample of preschool children from Palermo. Gross motor development was expressed as a composite score of a set of fundamental motor skills across the two gross motor skill domains. We observed a positive effect of PEP on gross motor development in the studied population. In particular, IG showed a significant increase in both locomotor (p < 0. These findings are consistent with those of previous studies that investigated the effect of PE on preschoolers' gross motor skills (Derri et al. For instance, Derri et al. Analysis of the covariance and gain scores confirmed the positive effect of our intervention in the rise of children's gross motor skills, even starting from different pre-test scores.
The effective use of obtain results or ANCOVA could have been largely contended in past times throughout the data from pre-test/post-attempt habits. As ANCOVA is suitable just for randomized managed samples and you may is also prejudice results in non-comparable communities or observational habits, the research from obtain results offers compatible, objective evaluation for some search activities (Ragosa, 1995). In the absence of fruzo ücretsizdir randomization, when standard differences between teams exists, change-rating models give less biased rates (Allison, 1990). Centered on QGMD scores recommended by the manual’s recommendations, we unearthed that IG increased the fresh new gross engine efficiency away from average so you can significantly more than mediocre in contrast to CG, and therefore did not show people relevant change. At the same time, the organization of one tutorial in several sub-phases (social-heat up, central, cool-down-views stage) are an appropriate means to fix boost kid’s involvement.
