BM chapter 2 - Behavioral assessment: measurement of the target behavior in BM. Its imp coz 1) measuring behavior before the treatment can help you determine whether treatment is necessary 2) Behavioral assessment can provide information that helps you choose the best treatment 3) measuring the target behavior b4 & after the treatment allows you to determine if the behavior changed after the treatment. Two types of BA: 1) Indirect assessment: involves using interviews, questionnaires and rating scales to obtain information on the target behavior from the person exhibiting the behavior or from others. Information on the target behavior depends on peoples memories. May also be based on incomplete info about TB thats why we rely on direct assessment. 2) Direct assessment: a person observes and records the target behavior as it occurs. Usually more accurate than indirect assessment coz observer is trained specifically to observe the TB & record its occurrence immediately. A) The observer must be in close proximity to the person exhibiting the behavior so the target behavior can be seen or heard in the case of camera usage B) Observer must also have a precise definition of the target behavior so that its occurrence can be distinguished from occurrences of other behaviors. C) To record the target behavior (TB) observer must register the occurrence of the behavior when its observed. - Defining target behavior: 1 step in developing a behavior-recording plan is to define the TB u want to record. To define TB u must 1) identify exactly what the person says or does that constitutes the behavioral excess or deficit targeted for change. A behavioral definition includes active verbs describing specific behaviors that a person exhibits and it is objective and unambiguous. Ie it doesnt refer to internal states such as being angry. A behavioral definition does not make inferences about intentions coz they can be observed and recorded. And labels cant be used to define behavior. Labels for behavior are ambiguous; they can mean different things to different people. i.e repeating words and syllables is not caused by stuttering it is a behavior called stuttering. the main value of labels is that they may be used as convenient shorthand when referring to a target behavior. However, the behavior must always be defined before it can be observed and recorded.
