Time 1 and time 2 correlate highly 0. 80 or higher (self report data) Inter-rater reliability if two people are observing the same situation in one point in time they would agree as to what they are seeing. Used with 2 or more raters (observation data) Internal consistency reliability describing the inner cohesion of the scale, because we are creating & distributing the scale we need to make sure the scale is strong. The scale needs to be consistent, and give the same results overtime when repeated on same study. Degree to which test measures what it claims to measure capture what its supposed. Types of validity: are captured by different means: face validity, extent to which a scale gives you what its supposed to measure.
