The main outcome of the study that researchers were concerned with was the duration of joint engagement. The JASPER group, when compared to the PEI group, showed a significant increase in length of time the child participants spent jointly engaged with parents. For initiating joint attention and number of symbolic play types, no major progressions or increase in data for either group occurred. For the number of functional play types, data showed that the JASPER group increased more in different types of functional play compared to the PEI group. Similarly, the JASPER group also increased more in highest play level achieved compared to the PEI group. Both groups yielded increase in receptive language and expressive language, and no significant differences were found between each group’s data. The PSI (child domain) results showed “…that parents in the PEI group experienced a larger reduction in child-related stress over time as compared with parents in the JASPER group…” (2015). The PSI for parent domain did not yield any significant differences in results comparing both groups. For classroom observations, results indicated that children in the JASPER group improved significantly more than those in the PEI group in the amount of time spent jointly engaged with the …show more content…
Ethical issues were addressed appropriately. Because participants were minors, informed consent was obtained from the parents prior to start of study. Also, a University Institutional Review board approved the study before it commenced. The study was associated with the University of California Los Angeles. Therapists that conducted training in the JASPER model were well trained; they were required to complete two to six months of training. Supervision of cases during training was conducted on a weekly basis. A high amount of treatment integrity was achieved for both PEI (92.7%) and JASPER (91.4%). Ensuring examiners of the treatment and video coders were blind to treatment conditions for each participant minimized
