In the development of a psychological instrument, two essential aspects of psychometrics i.e. 'reliability and validity' of the instrument is required. In the present study the questionnaire developers starts content validity process with a set of 122 items by computing Content Validity Index (CVI) using judges' ratings on each item by considering the item's 'relevancy and clarity' rated by the panel of seven subject experts. Their ratings were used to calculate the Item level content validity index (I-CVI) and scale level content validity index (S-CVI). Scale level content validity index (S-CVI) was calculated by using the average approach. On the basis of the I-CVI, decision for retaining, retaining, revising and excluding the items was taken. Modified kappa was also performed for adjusting chance agreement from the degree of agreement. The final SPQ contained 120 items.

In the development of a psychological instrument, two essential aspects of psychometrics i.e. 'reliability and validity' of the instrument is required. In the present study the questionnaire developers starts content validity process with a set of 122 items by computing Content Validity Index (CVI) using judges' ratings on each item by considering the item's 'relevancy and clarity' rated by the panel of seven subject experts. Their ratings were used to calculate the Item level content validity index (I-CVI) and scale level content validity index (S-CVI). Scale level content validity index (S-CVI) was calculated by using the average approach. On the basis of the I-CVI, decision for retaining, retaining, revising and excluding the items was taken. Modified kappa was also performed for adjusting chance agreement from the degree of agreement. The final SPQ contained 120 items.
