The present findings are also in line with Dunn and Bennett’s (2002) study, currently the only other study in which the long version of the SP was used with this population.
Dunn and Bennett’s comparison of section scores revealed statistically significant differences between the groups on all 14 sections, while in our study significant differences were found in 11 out of the 14.
In addition, the discrepancies in scores between the ADHD and the control group were larger than those found in our study.
In our analysis of the factor scores, significant differences were also found between the study groups on 6 out of 9 factors.
Since Dunn and Bennett did not report on the factor scores in their study, no comparison could be made on this component.
