riment among a small group of autistic children in different settings to analyze the results of multi-exemplar training to establish a repertoire of sharing behaviour.
Evaluating the research design using the Scientific Merit Rating Scale (SMRS) the writer would assign a rating of four to this design. This rating is based on the study using a single-subject design with four subjects in total. The researchers compared control and treatment data by using a concurrent multi-probe design and baseline treatment. The research design helped in maintaining uniformity and accuracy of the response of the subjects. Each baseline and treatment trials consisted of eighteen sessions each out of which 9 sessions were teaching sessions. The verbal offers for sharing were randomly assigned to each of the participants and the offers were rotated in each session. The order of trials was also randomized the only exception being the training trials which was conducted both before as well as after a session. There was no mention of data loss of any kind in the article.
Direct observation was adopted in the experiment to measure response which was done by trained observers using pencils and paper data sheets. The scoring of two observers was compared. Interobserver data was collected for all the subjects and the mean percentage was 99% across all the trials and all the subjects. Using the SMRS the researchers would rate the quality of dependent measure a five.
Each verbal instruction tasks and observation were specified. The mean percentage accuracy on procedural components was 99%. Subject wise individual integrity scoring was also done. A rating of four would be given according to SMRS since the overall accuracy was above 80 and implementation accuracy as studies in at least 25% of the sessions for each participant.
The four children who participated in the study were diagnosed with autism. The diagnosing was done by independent agencies. The 4 participants studied in a school
