I’m trying to make sense of the screening data provided by Prolific.
Here are the details:
I ran a study to get responses from people with a diagnosis of Autism Spectrum Disorder (ASD). I selected this as an eligibility criterion on Prolific, i.e. Custom Screening > Autism Spectrum Disorder > “Yes - as a child” or “Yes - as an adult”. However, when I download the sample data (More > Download export), only half of the participants have an entry for the Autism Spectrum Disorder question. The rest have N/A.
Further, I administered a standard questionnaire of behaviours associated with ASD (Autism Quotient). It turns out that a lot of the participants from the “ASD” sample also do not meet the cut-off criteria for autism on that questionnaire. So, I’m wondering if I set the eligibility criteria correctly.
I’d be extremely grateful if anyone who did studies with clinical groups on Prolific shared their experience.
