Abstract
Objective: To construct a scale for measurement of
rumination among traumatic amputees while utilizing
a Pakistani cohort.
Methodology: This was the first part of a scale
development and validation study carried out from
February 2018 to March 2019 including amputees
from multiple centers. We carried out thematic
analysis of lived experiences and perspectives on
complex phenomenon on 30 amputees and generated
an item pool. Seven experts first evaluated the item
pool and then Content Validity Ratio (CVR) was
calculated. Item reduction analysis was carried out
while recruiting 50 amputees using Cronbach’s alpha
evaluation. Factorial Validity and Internal Consistency
of the scale was determined on evaluating 200
amputees through Exploratory Factor Analysis (EFA).
Results: The CVR ≥ 0.99 and pilot study indices were
the criterion for item inclusion. Items were selected for
the scale measuring rumination. This scale comprised
of three sub scales, each having value of Cronbach’s
alpha as 0.90, 0.87, and 0.89. To establish factorial
validity, EFA identified three-factor solution and all
three emerged factors had Eigen values > 3. Six items,
each for three factors, accounted for almost 44% of the
total variance.
Conclusion: Rumination Scale for Traumatic
Amputees is a new scale developed in Urdu for the
measurement of rumination among traumatic amputees
in Pakistan.
Keywords: Rumination Scale, traumatic amputees,
statistical factor analysis.
