Background:
The SCOOHPI scale (Schizophrenia Coping Oral Health Profile and Index) assesses the coping strategies of schizophrenic patients in terms of oral health. In this article, we explore the sub-concepts assessed by the SCOOHPI scale to use it as a profile.
Methods:
We studied the internal consistency of the items of the SCOOHPI scale; then, the structural validity of this scale was examined using a principal component analysis. Finally, we studied the relationship between the SCOOHPI scale and sociodemographic and clinical variables.
Results:
The total sample consisted of 96 participants, including 72% men and 59% smokers. The SCOOHPI scale shows good internal consistency (α = 0.84). The principal component analysis reveals the existence of three sub-concepts assessed by the SCOOHPI scale.
Conclusion:
This study made it possible to examine the sub-dimensions of the SCOOHPI scale. This tool can contribute to a better assessment of the coping strategies of schizophrenic patients in terms of oral health. This study provides a preliminary validation of the SCOOHPI scale as a profile. Further confirmatory studies on independent samples are needed to confirm its factor structure.
