Abstract
ABSTRACT
Background
The Neuroticism subscale of the Eysenck Personality Questionnaire Revised Short
Form (12 items) (EPQRS-N) has proven to be a reliable and valid measure in multiple
languages.
Objective
To develop a single-factor Nepali-language version of the EPQRS-N for use in the
adult population of Nepal.
Method
The original English version of EPQRS-N was translated into Nepali using a forward-
backward translation protocol. The first set of translated items was modified after
testing by factor analysis with principal component extraction in an outpatient
sample. Items with low factor correlations or poor semantic consistencies were
reworded to fit the gist of the original items in a Nepali cultural context; the revised
version was then tested in a representative random sample from the general
population. Again, the same statistical procedures were applied.
Results
The first trial gave three factors. Based on the factor distribution of the items or
their semantic quality, five were reworded. In the second trial, a two-factor solution
emerged; the second factor had only one item with high correlation, which also had
modest correlation with the first factor. Accordingly, a forced one-factor solution was
chosen. This gave an internal consistency (Cronbach’s alpha) of 0.80, with item-to-
factor correlations from 0.40 to 0.73, and item-to-sum correlations from 0.31 to 0.61.
Conclusion
The final Nepali version of EPQRS-N achieved satisfactory internal consistency. The
item distribution coincided with the original English version, providing acceptable
construct validity. It is psychometrically adequate for use in capturing the personality
trait of neuroticism, and has broad applicability to the adult population of Nepal
because of the diversity of the participant samples in which it was developed.
