NCT03834064

Brief Summary

A Phase II cluster randomized controlled trial of the (OHPROM) strategy/intervention will be conducted in partnership with several organizations that provide residential services for persons with intellectual developmental disabilities (IDD) in north central Kentucky and southern Indiana. The investigators have identified a purposive sample of group homes, caregivers, and persons with IDD and have the support of these organizations.

Outcome Measures

Primary Outcomes (2)

  • 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.

    12 months

  • 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.

    12 months

Secondary Outcomes (6)

  • Change in caregiver self-efficacy from baseline to 4 months and 12 months in the experimental group compared to the control group of caregivers.

    12 months

  • Change in caregiver outcome expectancies from baseline to 4 months and 12 months in the experimental group compared to the control group of caregivers.

    12 months

  • Change in caregiver behavioral capability from baseline to 4 months and 12 months in the experimental group compared to the control group of caregivers.

    12 months

  • 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.

    12 months

  • 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.

    12 months

  • +1 more secondary outcomes

Study Arms (2)

Intervention

EXPERIMENTAL

Homes where participants with intellectual/developmental disabilities reside will be randomly assigned to the intervention arm. Caregivers working in that home will receive the oral health promotion strategy/intervention over the course of a year.

Behavioral: Oral health promotion strategy

Control

NO INTERVENTION

Homes where participants with intellectual/developmental disabilities reside will be randomly assigned to the control arm. Caregivers in that home will not receive the oral health promotion strategy/intervention over the course of a year but will be offered a compressed intervention after a year.

Interventions

The proposed intervention is comprised of four components : (a) planned action including a behavioral contract Activity 1) with caregivers and action planning for oral health (Activity 2), (b) caregiver capacity building with didactic training (Activity 3), observational learning and caregiver practice (Activity 4); (c) environmental adaptations with location of oral health activities and reminder posters - physical environment (Activity 5) and administrative oral health support- (social environment (Activity 6); and (d) reinforcement with caregiver coaching (Activity 7).
