Internal consistency reliability addresses the correlation of each question to other questions within the scale.Alternate forms reliability seeks to determine whether two forms of an instrument measure the same attributes.Interrater reliability measures whether two or more observers measure the same attributes.Test-retest reliability measures whether the same attribute is consistent from one testing time to another.
