PSYB01H3 Chapter Notes - Chapter 9: Regression Analysis, Time Point, Internal Validity
Document Summary
We are oftentimes too quick to attribute improvement of client to own treatment. Single subject = one subject, small-n designs = 1 9 subjects. Focus on one individual: clinical processes of assessment, establishing intervention goals and specific outcomes, providing intervention and evaluating progress. An in-depth study of a single or relatively few subjects under tightly controlled experimental conditions in which the independent variable(s) is repeatedly manipulated over successive trials or conditions and in which the dependent variable(s) is repeatedly measured. Stable line: line that is relatively flat, little variability, changes easily detected. Trends (scores may be either increasing or decreasing during baseline period): variable flat-line. Linear trend (increasing or decreasing at a constant rate: curvilinear trend (rate of change is accelerating over time, cyclical (regular increase and decrease) Chapter 9 small-n and single-subject designs: no pattern: get more data points to make certain about pattern or lack of, internal validity.
