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.
Performance
Within baseline, CG and you can IG don’t show one significant variations (p blk hesap silme > 0.05) with respect to gender, chronological many years, weight, height, Body mass index and you can terrible engine reputation, just like the revealed inside the Dining 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.

Figure 3. Score of locomotor and object control skills after 16 weeks of physical education program. ??? p < 0.01, compared with pre-test.
Table step 3 displays that exact bits of locomotor and you may target handle knowledge don’t upsurge in the fresh new manage class after the fresh several months, while a very significant improve are observed in all the items into the IG as a result to PEP.
Most of the pre-literacy knowledge somewhat improved from inside the IG pursuing the intervention months, during CG only the amount of problems into naming away from items somewhat reduced (discover Table 4). not, brand new analyses of obtain results and ANCOVA failed to tell you one extreme feeling from the input between CG and 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 application of gain scores otherwise ANCOVA has been mostly debated in past times regarding the analysis regarding pre-test/post-take to patterns. As ANCOVA is acceptable just for randomized controlled trials and you will can bias contributes to non-comparable groups or observational activities, the analysis out-of acquire score provides for suitable, unbiased evaluating for the majority search habits (Ragosa, 1995). About lack of randomization, when standard differences when considering groups exist, change-get activities give less biased quotes (Allison, 1990). Predicated on QGMD ratings recommended by the manual’s rules, we found that IG improved the latest terrible motor show off average so you can a lot more than average in contrast to CG, hence don’t let you know people related transform. On the other hand, the company of a single class in many sandwich-levels (social-heat up, main, cool-down-feedback stage) was a suitable treatment for increase kid’s contribution.
