SXI-Y: Young Adult Xerostomia Inventory Factor Loadings

278 students aged 18–24 from two California public universities completed a survey to develop a xerostomia (dry mouth) assessment tool for young adults. The resulting 5-item Young Adult version of the Shortened Xerostomia Inventory (SXI-Y) demonstrated excellent internal consistency (Cronbach alpha = 0.817) and strong correlation with a global dry mouth measure. Author Benjamin W. Chaffee published the factor loadings and item response coefficients on figshare in May 2026.

Use Cases

• Validate a brief xerostomia assessment tool based on the 5-item SXI-Y scale.
• Analyze associations between xerostomia and oral health conditions like gum bleeding, oral pain, and halitosis.
• Investigate links between xerostomia and risk indicators such as prescription medication use, nicotine or cannabis use, sleep, and stress.
• Compare psychometric properties of a young adult-specific instrument against tools developed for older populations.

Strengths

• Dataset includes psychometric validation results with specific metrics like Cronbach's alpha (0.817) and polychoric correlation (0.711).
• Study population is clearly defined as 278 students aged 18–24 from two California universities.
• The 5-item scale is derived from a 14-item inventory using exploratory factor analysis and item response theory.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects a specific geographic and demographic bias (young adults at California universities).
