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.
Efficiency
During the standard, CG and you will IG failed to tell you one extreme variations (p > 0.05) with regards to intercourse, chronological many years, lbs, height, Body mass index and you can disgusting motor profile, while the revealed inside the Table dos.
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.

Table step 3 displays that specific items of locomotor and you may target control experiences didn’t rise in the brand new control category pursuing the fresh period, when you are a very high increase are seen in all the items from inside the IG in response so you can PEP.
The pre-literacy knowledge notably increased in the IG after the input several months, during CG just the number of problems towards the naming off items significantly diminished (get a hold of Dining table 4). not, new analyses away from gain score and ANCOVA didn’t reveal any high effect about input between CG and you will IG.
Conversation
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.
Using get score otherwise ANCOVA has been mainly argued before in the research of pre-test/post-sample activities. As the ANCOVA is appropriate only for randomized regulated examples and you can can prejudice contributes to non-comparable groups or observational activities, the study out-of gain scores offers compatible, objective assessment for some lookup activities (Ragosa, 1995). About absence of randomization, when baseline differences between groups are present, change-rating habits give less biased prices (Allison, 1990). Predicated on QGMD score suggested by manual’s guidelines, i found that IG improved this new terrible system performance away from average so you’re able to significantly more than mediocre weighed against CG, which don’t let you know one associated changes. As well, the firm of just one lesson in a lot of sub-levels (social-warm up, central, cool-down-opinions stage) are a suitable way to increase children’s involvement.
