Document Summary
Iq: alternate-form reliability: using two forms of tests rather than giving the same test twice, perhaps when there is concern that people will remember their answers from the first test and aim merely to be consistent. Internal consistency reliability: assesses whether the items are related to one another (like on an anxiety questionnaire all the questions are related to anxiety) In each of these types of reliability, a correlation (measure of how closely 2 variables are related) is calculated b/w raters or sets of items the higher correlation, the better the reliability. Structured interviews: one in which the questions are set out in a prescribed fashion for the interviewer: structured clinical interview diagnosis (scid) for axis 1 of dsm-iv. Branching interview (client response to one question determines the next question asked) Rated on a 3 point scale of severity. Also developed for diagnosing personality disorders and more specific disorders.
