Hi all,

Can anybody help me out how I can prevent STATA from reversing the data of aut3? Students filled in a survey with a five points lickert scale and I already reversed the data of the negatively asked questions myself (before entering the data in STATA).

. alpha aut1 aut2 aut3 aut4 aut5 aut6 aut7 aut8

Test scale = mean(unstandardized items)
Reversed item: aut3

Average interitem covariance: .2150992
Number of items in the scale: 8
Scale reliability coefficient: 0.7011

. alpha aut1 aut2 aut3 aut4 aut5 aut6 aut7 aut8, item

Test scale = mean(unstandardized items)

average
item-test item-rest interitem
Item Obs Sign correlation correlation covariance alpha

aut1 104 + 0.6266 0.4687 .2044125 0.6554

aut3 104 - 0.4409 0.2481 .2414382 0.7019

aut7 104 + 0.4360 0.2311 .2423806 0.7069
aut8 104 + 0.5751 0.3840 .2120941 0.6742

Test scale .2150992 0.7011
