PSY 2301 Study Guide - Midterm Guide: Inter-Rater Reliability, Mental Disorder, Multiple Choice
Document Summary
Consistency of responses across items on measure (cronbach"s alpha: 0. 6-0. 7 acceptable, 0. 7-0. 8 good, 8-1. 0 very good) abnormality is binary (present or absent) Examine effect of experimentally manipulated: follows same person over time. Categorical approach: suicide rates higher for caucasian as opposed to non. Inter-rater reliability: external validity abnormality lies on a continuum may provide more valid portrayal of many clinical phenomena. Consistency of judgements across raters (kappa > 0. 75: internal validity. Generalizability of findings beyond study extent to which diagnostic category accurately captures abnormal phenomenon. Extent to which causal interpretations justified and alternative causal explanations ruled out. Examine associations btw two variables (predictor and outcome) for multiple people: facilitates communication about disorders. As internal validity increases, external validity: consistency of responses over time (r > 0. 7 good) Between-subject design: to define different "mental disorders" to make sure people get the services they need.
