Alogram evaluation of these data was .Also, Rasch model showed that their item tests match a single scale construct.Furthermore, the partnership among age and Guttman scale score and Rasch Model was also calculated (r ) .Hutchins et al. that created PCToMME questionnaire reported criterionbased construct validity in regular young children and in these with ASD.Inside the ASD group, the Pearson correlation was .involving verbal mental age (VMA) and ToM tasks; Spearman correlation was .involving PCToMME and ToM task; and Spearman correlation was .among the predictive measure of ToM skills plus the ToM tasks.Inside the normal group, Pearson’s correlation showed a signification partnership among child’s age and PCToMME score (r ).Also, the distinction between judgments of ASD mothers and typical mothers about young children was significant (P), supporting construct validity.For face validity, they followed the literature, and every item was Cyclic somatostatin Biological Activity developed in order that it was a face valid indicator of child’s information.To evaluate the convergent validity on the PCToMME, of products on a ToM activity battery that had been identified to possess superior test etest reliability had been administered, and consisted of test concerns inside seven tasks.Testretest reliability in a single week apart in ASD and typical kids was .and respectively and it was .in .month apart in ASD group .BlijdHoogewys, Greet, Serra and Minderaa studied two sorts of validity (content material and construct validity) and three types of reliability (testretest, interrater reliability and internal consistency).For content material validity, they studied the correlation of subtypes of ToM in three groups that varied from .to .For construct validity, they tested each convergent and divergent validity of ToM storybooks.Regarding convergent validity, correlation with 3 related tests was calculated and it was involving .and .For divergent validity, correlations with language and intelligence tests had been calculated by Pearson productmoment correlations, which had been among .and .The test etest reliability for regular young children was PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21602316 .and it was .for PDD_NOS.Moreover, Cohen’s kappa scale was employed to assess interrater reliability.The correlations involving five raters have been ..For internal consistency, Cronbach’s alpha was utilized and correlation for age varied and it was .for dichotomous things .O’Hare, Bremner et al. studied only interrater reliability, in which correlation involving 3 raters was aside from the banana `pretense’ story exactly where it was .Iranian J Psychiatry , Sep ijps.tums.ac.irComprehensive Theory of Thoughts Tests ReviewHutchins et al. evaluated testretest reliability, internal consistency and criterionrelated construct validity of ToMI.For testretest reliability, Pearson’s solution moment correlation was calculated for ASD and normal young children, using an interval of days (in both of group, r ).Internal consistency was assessed utilizing Cronbach’s alpha .Also, criterionrelated validity was .and .in ASD and regular youngsters, respectively.Construct validity was .and .in two groups, respectively .Mohammadzadeh, Tehranidoost and Khorrami had no report regarding the validity and reliability of their computerized test and just explained that their test was based on original ToM test developed by Castelli and Frith .Tahiroglu et al. described crossvalidation data for the CSUS within a distinct sample of preschool children with a distinctive set of ToM tasks.Also, they studied internal consistency, test etest reliability, and relation of the scale to children’s pe.
