When parents are taught to use applied behavioural techniques family context can be addressed (Moes & Frea, 2002), twenty-four hours a day. Generalization is more likely to occur for both the parents using this coaching, and for their children receiving the training. Parental behavioural instructional methods, usually with mothers, have had positive effects on childrens behaviour, although no studies follow-ups have been monitored past a year (Bergstrom, 2013; Csapo, 1979; Muir & Milan, 1982). This study with children diagnosed with autism begins when they were four-years-old and follows their varied diagnoses and development until their nineteenth years. Voluminous behavioural techniques were utilized over the 14 years in conjunction with numerous behaviours and settings. Some of the examples being presenting include shaping and fixed ratio scheduling in toilet training, variable ratio schedules for eating, and fixed ratio with limited hold to elicit appropriate hygiene. Results indicate constant parental use of behavioural methods produce significant changes in their childrens behaviour allowing for an increase in abilities and life skills.
