Summary View help for Summary
The Requests for Assistance with Adaptive Switches from Individuals with Severe Communication Impairments study is one of the three projects in the Communication of People with MR, 2006 to 2012 Series, which focuses on identifying participant variables that predict success in increasing communication skills of individual with intellectual disabilities. The study data were collected to show how children and adults with profound multiple impairments can learn to request assistance with adaptive switches and to on examine the change from pre-intentional to intentional symbolic communication.
The study examined 77 respondents, ages 2 through 71, by administering three assessments: the Communication Complexity Scale (CCS), the Mullen Scales of Early Learning and a functional vision assessment. The CCS was administered to 68 respondents on up to three occasions. The first occasion of administration was to participants who were pre-intentional communicators. The CCS was administered on a second occasion to participants when they were identified as being on the cusp between pre-intentional and intentional communication. The third and final occasion of administration occurred when participants were identified as "learners" and could express preferences using switches and other means.
The Mullen Scales were administered to 22 of the participants. Of the 77 participants initially selected for the study, 7 did not complete either scale. Vision impairment was identified in 68 respondents, 28 who had no functional use and 41 who had some functional use of their vision.

This study is one of the three projects in the Communication of People with MR, 2006 to 2012 Series. The other two studies in this series are:
- Language Development of Non-verbal Children Age 3 Years through 7 Years, 2007 to 2012 [Kansas City Metro Area] (ICPSR 36472)
- Young Children with Physical Disabilities, 2007 to 2012 [Seattle, Washington] (ICPSR 36516)
This study used two scales. The Communication Complexity Scale, which was developed for the Communication of People with MR 2006 to 2012 series, and the Mullen Scales of Early Learning. For more information on the Communication Complexity Scale, see the following publication:

The Communication Complexity Scale (CCS) was administered on up to three occasions to study participants. The first occasion of administration was to participants who were pre-intentional communicators. The CCS was administered on a second occasion to participants when they were identified as being on the cusp between pre-intentional and intentional communication. The third occasion of administration occurred when participants were identified as "learners" and could express preferences using switches and other means.
Sample View help for Sample
Respondents were convenience sampled through their participation in a requesting-via adaptive-switch intervention. Respondents were selected from the group participating in the intervention because of their severe and multiple disabilities and suspected vision impairments. Respondents were between ages 2 to 71 years.

2016-10-25 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Standardized missing values.
- Checked for undocumented or out-of-range codes.
The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.
