Validation of ageism scale for dental students in India: (Ageism Scale for Dental Students- India) - a cross sectional study

Ageism scale for dental students (ASDS): A focus group review of content validity

PURPOSE/AIM

Improve content validity of the Ageism Scale for Dental Students (ASDS) and identify barriers to using the scale.

METHODS

Thematic analysis of transcripts of three purposively sampled focus groups of 1) geriatric dentistry specialists, 2) older adult dental patients, and 3) dental students.

RESULTS

Twenty-five participants engaged in focus groups. No new concepts to define ageism were identified. Experts found the scale acceptable and appropriate, yet they raised specific potential revisions to scale questions. Commonly reported themes already addressed by ASDS included the importance of tailoring decision-making to patient preference and not making assumptions about older adults' capacity or preferences for dental care. Barriers to identifying ageism or using the scale included experiential differences in interpreting scale items, cultural differences in attitudes towards older adults, and potential overlap with social determinants of health. Secondary findings include recommendations for older-adult focused training for dental students to provide positive, concrete guidance on caring for older adults.

CONCLUSION

There are opportunities to refine the Ageism Scale for Dental Students and to allow tailoring of the scale for specific national or cultural contexts.

Translation and validation of ageism scale for dental students into Malay language

AIMS

Identifying ageism among dental students is essential in gerodontology courses. This study aimed to perform a preliminary validation of a Malay version of the ageism scale for dental students (ASDS-My).

METHODS AND RESULTS

The 27-item ASDS were translated into Malay language and completed by 168 dental students. Exploratory factor analysis (EFA) with Promax rotation, Polychoric Correlation Matrix and Principal Axis Factoring was conducted. Internal consistency reliability and discriminative validity were analysed. Criterion validity was measured by comparing ASDS-My with Fraboni Scale of Ageism (FSA). A Kaiser-Meyer-Olkin of 0.612 and a Bartlett's Test of Sphericity yielding p < .001 confirmed the adequate factorability. EFA revealed a 15-items scale distributed into five-factors explaining 54.5% of overall variance, with acceptable reliability. The two factors involved cost-benefit of dental treatment on older patients and challenges during medical history taking. The third, fourth and fifth factors explained attitude towards older patients, negative views of older patients and exposure of dental students to Gerodontology training and experiences respectively. Most factors were significantly positively related to FSA. Discriminative validity revealed significant differences for gender, place of stay and year of study.

CONCLUSION

Preliminary validation of the ASDS-My produced a five-factors 15-items scale with acceptable validity and reliability.
