 Procedure. After a family has been assessed as eligible for the study, and have signed consent forms to participate in the study, they will be given an appointment time to attend the nursery setting for pre-measures. One parent will be asked to engage in free play with their child similar to how they would at home using a standardized set of toys. The parent will be video recorded playing with their child for a ten-minute period, and then asked to answer the three questionnaires. This procedure will occur at baseline Time 1, within 2 months of diagnosis, and after the treatment period Time 2, at least four months after the baseline measure. After base-line measures, families will be randomly assigned to the treatment group, and the waitlist group, using a random numbers table and a pre-arranged opaque envelope system. Treatment group parents will then be given access to participate in the on-line self-directed parent training and support intervention between Time 1 and Time 2, and the waitlist group parents will be given access to the intervention after Time 2. Parents will be given codes to access the on-line resources to ensure their anonymity to other participants. The codes will also allow the principle investigator to track when parents access the on-line training and support and when they have completed the on-line training. When treatment group parents have completed the on-line training and after at least a four-month period has elapsed since the baseline measure the parent and child will be invited back to the nursery setting for Time 2 measurements.
