Home Administration
One or two research staff members visited the child’s home, brought the BOSCC kit, videotaped, and assisted with timekeeping. Research staff used a script to provide directions to parents to “play with the toys in the kit as [they] normally would play” and prompted transitions (i.e., end of free play, start of bubble play). Other than these instructions, parents were not otherwise trained to administer the BOSCC, however the BOSCC has been used successfully in previous research to code unstructured parent-child free play (Grzadzinski et al., 2016). Parents selected a space with minimal distractions where they could play uninterrupted with the child for the duration of the assessment.
