Autism-Spectrum Quotient-Japanese version and its short forms for screening normally intelligent persons with pervasive developmental disorders . A Japanese version of the Autism Spectrum Quotient ( AQ ) , AQ-J was administered to 25 normally intelligent high-functioning pervasive developmental disorder ( HPDD ) patients ( mean age , 24.2 years ; 24 male , one female ) and 215 controls ( mean age , 30.4 years ; 86 male , 129 female ) randomly selected from the general population . The AQ-J had satisfactory internal consistency reliability ( Cronbach 's alpha > 0.70 in the two groups ) , test-retest reliability , and discriminant validity [ i.e . the AQ-J score was significantly higher in the HPDD ( mean , 29.6 ) than controls ( mean , 22.2 ) ] . At a cut-off of 26 , the AQ-J had satisfactory sensitivity , specificity , and negative predictive value , but it had low positive predictive value ( 0.24 ) possibly due to the facts that the 25 mild HPDD patients scored lower and the controls scored higher on the AQ-J than British counterparts on the AQ . The AQ-J-21 ( consisting of 21 items significantly associated with HPDD diagnosis ) and the AQ-J-10 ( consisting of 10 of the 21 items with an effect size > 0.17 ) had higher , although not satisfactory , positive predictive values of 0.35 and 0.46 at cut-offs of 12 and 7 , respectively , than the AQ-J . The AQ-J and two short forms are useful not to predict but to rule out mild HPDD , the most difficult part of HPDD to be distinguished from non-PDD conditions , in persons scoring under the cut-offs and to consider professionals ' examination of HPDD in persons scoring over them , because their negative predictive values were satisfactory .
