a

Scores reversed

b

This is the correlation of the item designated with the summated score for all other items.

c

This represents the scale’s Cronbach’s alpha reliability coefficient for internal consistency if the individual item is removed from the scale. This value can be compared to the Alpha coefficient value at the bottom of the table to see if one wants to delete the item.
