Introduction: Access to oral healthcare services for people with disabilities continues to
be an issue. The accessibility measuring tool is limited or not exclusive to children with
cerebral palsy (CP). Accessibility of children with CP to oral healthcare services (CP2OHS)
is a new questionnaire that was developed, and exploratory factor analysis (EFA) is a
preferable procedure in determine and refining meaningful underlying constructs.
Objectives: The objective of this study is to determine the internal structure of the
CP2OHS questionnaire. Materials and methods: The caregivers of children with CP who
had registered with the Kelantan Department of Welfare were invited to participate in the
study and completed the CP2OHS questionnaire via telephone interview. EFA and
reliability analysis were used to determine correlations among measured variables on the
particular constructs. Results: The caregivers of 106 children with CP took part in the
study. The final model of the CP2OHS questionnaire in the EFA has 28 items with factor
loading > 0.4, and loaded across five factors namely Abilities to Perceive, Ability to Seek,
Ability to Reach, Ability to Pay and Ability to Engage. Three domains obtained Cronbach’s
Alpha values above 0.7 which are Ability to Perceive (α = 0.834), Ability to Seek (α = 0.822),
and Ability to Pay (α = 0.725). Both Ability to Reach (α = 0.679) and Ability to Engage (α =
0.597) presented with Cronbach’s Alpha below the recommended value of 0.7.
Conclusion: The process of implementing appropriate and successful measures to
increase access to oral healthcare services require knowledge of the barriers. The CP2OHS
questionnaire can be integrated for the detailed assessment of perceived access to oral
healthcare services. The application of the measure may enhance understanding and
recognition of the barriers to accessing oral healthcare services by the caregivers of
children with CP.
