Pilot study
A pilot study was conducted to identify and investigate the
feasibility of the proposed study and detect any errors in the
data collection instruments.Any changes made to the instruments
were tested for reliability using Cronbach’s alpha test
to assess internal consistency or reliable acceptable results.
The Cronbach’s alpha value for the 20 items in the DMSESscale
was found to be highly reliable (a = 0.951). The Cronbach’s
alpha value for the 10 items in the SDSCA scale was
a = 0.740.
