Reliability Analysis - Doubt of Alpha de cronbach in item sign


Good morning, I'm doing a reliability analysis and I have positive and negative items in my survey. My question is how to interpret the signs reported by the items, that is, to know when I have to revert items based on these resulting signs.

Ex.
Positive items: item1, item2, item3, item4, item5 item6 item9 item11
Negative item: item 7 item8 item10 item12

Annex the result obtained for better support.

in this case I still do not reverse the negative items, I have not done the collection or database, so since I do not have information about it I would like to know how is the address of the item.

You may wish to type - help alpha - and check, among other interesting aspects the information on the ‘asis’ option. Also, the third paragraph of Remarked and Examples.

In short, Stata automatically - and empirically - catches the sign.

You may let Stata convert it automatically. You may as well recode previously, with (probably) the same results. You may finally take each item ‘as is’, or treat the coefficients in absolute terms. To follow specifically the field of the research, taking a look at previous articles is helpful.
