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

Background: Ageism persists in many different societies as it is innate and subconscious in nature. Negative effects such as loneliness, mistreatment, and occupational discrimination are frequently present due to ageism. The dental students in our study were wary of the possible benefits of expensive dental care because ageism is rife in their field. There is no validated and reliable ageism scale to assess how dental students perceive ageism in India. The current study was carried out to validate the ageism scale for dental students in the Indian context.

This was a cross sectional analytical study carried out among both males and females in Manipal College of Dental Sciences, Mangalore in which the instrument was 27-item Ageism scale for dental students. Content validity was done by six subject experts. The final version was administered to 213 students/Residents of dental school. The factorability of data was confirmed with KMO = 0.61 and Bartlett's Test of Sphericity resulting in p < 0.001.

Final PCA model resulted in 15 items and six components that together accounted for 70.37% of overall variance. The six components had reliability ranging from marginal 0.51 (Component 6) to a high of 0.81 (Component 3). As per the gender differences by component females showed less ageism than men in "non-compliance" (-0.9(-1.66-0.14), p<0.05) and "practitioner perspective" (1.43 (0.84, 2.03), p<0.01). Statistical significance was seen in Barriers/concerns in dental treatment of elderly where residents showed reversed (1.4 (0.41, 2.38), p<0.01). Urban group showed more ageism for component 'time restraint' (-0.79 (-1.57, -0.02), p<0.05.

Preliminary validation resulted in 15 item scale with six components with acceptable validity of the ageism scale and could be further tested in large samples. This scale will help recognize ageism in Indian context and provide necessary information to make changes in the curriculum as required.
