Reliability in behavioral assessment is derived through the calculation of interobserver agreement. Describe how interobserver agreement can be impacted by such issues as reactivity, observer drift, observer bias, complexity of response codes, and expectancy bias. End your post with a description of methods for calculating interobserver agreement and the various issues associated with the calculation methods.
These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.In behavioral assessment, reliability is derived through the calculation of interobserver agreement (Cooper, Heron, and Heward, 2007). Interobserver agreement can be impacted by many issues. The first one is reactivity, an error in measurement that results from an observer’s awareness that others will be evaluation the data he/she reports. This is similar to reactivity of participants when they are aware their behavior is being observed by others. During a study, an interobserver agreement is usually checked periodically. The observers are usually aware when their observations checks occur, by seeing another observer entering the situation or by observing...
