Interventions

Intervention 1: Experiment group: The Ziggurat Model begins the process with an assessment of individual strengths and concerns related specifically to ASD and identifies interventions across five tie

control group will receive simultaneously a shorten version of the program in 4 sessions

in order to manage Hawthorne effect. If the results for experiment group are suitable, the control group will also benefit similar training opportunity.
