Dear Stata users,
I'm currently working on my master thesis aiming to identify careless responding. As one indicator I'd like to use the even odd consistency.
I've already splitted the scales by even and odd items, caculated the subscale means, paired all even subsclaes with all odd subscales and calculated a correlation. Afterwards I applied Spearman-Brown Prophesy formula.
This is my code so far:
egen x_even = rowmean(x2 x4 x6 )
egen x_odd = rowmean(x1 vx3 x5 x7)
egen y_even = rowmean(y2 y4)
egen y_odd = rowmean(y1 y3)
egen z_even = rowmean(z2 z4 z6)
egen z_odd = rowmean(z1 z3 z5)
corr x_even x_odd y_even y_odd z_even z_odd
local sbpf 2*r(rho) / (1+r(rho))
di `sbpf'
My question is: How can I now assign an index value to each respondent based on this analysis?
I am very grateful for any help!
Best regards
Sina
