Autism Res. 2016;9(8):838–45. This paper examines the age neutrality of the Social Communication Questionnaire (SCQ); the authors “suggest that evidence indicating the lack of age neutrality of the SCQ indicates that the SCQ cutoff scores may need to be re-evaluated with consideration for age and/or that SCQ items themselves may need to be modified with respect to age.”

Psychometric analysis of the Social Communication Questionnaire using an item-response theory framework: implications for the use of the lifetime and current forms. J Psychopathol Behav Assess. 2015;37(3):469–80. This paper compares the two versions of the SCQ, and found that (i) the SCQ Lifetime form indicated sufficient psychometric properties and (ii) measurement issues emerged with respect to the SCQ Current form. The authors caution researchers and clinicians about the use of the SCQ Current form.
