| Primary |
The primary outcome of this study is the change in the oral health status of persons with IDD at 4 months and 12 months in comparison to the control group, after controlling for oral health status at baseline as measured by the Modified Gingival Index. |
Primary Outcome Measure the Modified Gingival Index (MGI). The MGI assesses the gingival condition, with scores ranging from 0 (no inflammation) to 4 (severe inflammation). Score range 0-128, higher is worse. |

The primary outcome of this study is change in the oral health status of persons with IDD at 4 months and 12 months in comparison to the control group, after controlling for oral health status at baseline as measured by the Community Periodontal Index. |
Primary Outcome Measure the Community Periodontal Index (CPI). The CPI assesses periodontal disease from a score of 0 (healthy - absence of periodontal disease) to 4 (deep pockets - severe periodontal disease). Score range 1-40, higher is worse outcome. |

| Secondary |
Change in caregiver self-efficacy from baseline to 4 months and 12 months in the experimental group compared to the control group of caregivers. |
Caregivers will self-report self-efficacy using an adapted version of the 10-item General Self- Efficacy Scale (Schwarzer, 1995). The adaptation was made to the lead-in statement in order to ask about general self-efficacy of Caregivers as they provide support to residents' oral hygiene and dietary practices. Response choices are: Never, Almost, Sometimes, Fairly Often, and Very Often. Score range 0-40, higher is good. |

| Secondary |
Change in caregiver outcome expectancies from baseline to 4 months and 12 months in the experimental group compared to the control group of caregivers. |
Caregivers will self-report outcome expectancies using an adapted version of Kakudate et al.'s (2010) 6-item Outcome Expectancies Scale. Response choices are: Strongly Disagree, Disagree, Agree, and Strongly Agree. Score range 0-48, higher good |
12 months |
|
| Secondary |
Change in caregiver behavioral capability from baseline to 4 months and 12 months in the experimental group compared to the control group of caregivers. |
Caregivers will self-report behavioral capability using an adapted version of Pradhan's (2016) Carer Activation Measure. Subscales of confidence (6 items) and skills (5 items) to measure behavioral capability. Response choices are: Strongly Disagree, Disagree, Agree, and Strongly Agree. Score range 0-44, higher is good. |

| Secondary |
Secondary outcomes are change in caregiver perceptions of environmental influences from baseline to 4 months and 12 months in the experimental group compared to the control group of caregivers. |
Caregivers will self-report environmental influences using a caregiver questionnaire developed specifically for this study, which assesses caregiver perceptions of the level of influence physical environmental influences (e.g., placement of posters as daily reminders) and social environmental influences (e.g., administrative support through policies and procedures). This is an 8-item scale. Response choices are: Strongly Disagree, Disagree, Agree, and Strongly Agree. Score range 0-32, higher is good. |

Change in Oral hygiene practices of persons with IDD will be measured by a dental oral examination guided by the Simplified Oral Hygiene Index (OHI-S) from baseline to 4 months and 12 months in the experimental group compared to the control group. |
The OHI-S has two components: the Debris Index and the Calculus Index. Each of these indices represents numerical determinations ranging from 0 (None) to 3 (Covering 2/3rd of tooth surface) of the amount of debris or calculus found on the preselected tooth surfaces. The six surfaces examined for the OHI-S are selected from four posterior and two anterior teeth. The buccal surfaces of the selected upper molars and the lingual surfaces of the selected lower molars are inspected. In the anterior portion of the mouth, the labial surfaces of the upper right (11) and the lower left central incisors The average individual or group debris and calculus scores are combined to obtain the Simplified Oral Hygiene Index. The CI-S and DI-S values may range from 0 to 3; the OHI-S values from 0 to 6. Higher scores indicate a worse outcome. |

Change in oral hygiene practices of persons with IDD will be measured by a caregiver-reported Daily Oral Health Checklist in the experimental group compared to the control group from baseline to 4 months and 12 months. |
The Daily Oral Health Checklist will be completed daily by each Caregiver for three days at all three time points in the study. These data will be used to calculate an index to assess Oral Hygiene Practices of residents' use (daily - yes/no) of oral hygiene devices as well as whether adequate time (at least one minute daily) was spent on oral hygiene activities, and whether hygiene activities were completed alone or with caregiver assistance. Dietary practices of persons with IDD will also be measured by the 3-day Daily Oral Health Checklist and completed by Caregivers to assess the frequency and timing of food and beverages that are good and bad for teeth and if caregivers cooperation strategies. |
