PSYB45: Behaviour Modification Textbook Notes Chapter 2: Observing and Recording Behaviour One fundamental aspect of behaviour modification is measuring the behaviour that is targeted for change. Measurement of the target behaviour (or behaviours) in behaviour modification is called behavioural assessment. Behavioural assessment is important for a number of reasons: o Measuring the behaviour before treatment provides information that can help you determine whether treatment is necessary. o Behavioural assessment can provide information that helps you choose the best treatment. o Measuring the target behaviour before and after treatment allows you to determine whether the behaviour changed after the treatment was implemented. Direct and Indirect Assessment There are two types of behavioural assessment: direct and indirect. Indirect assessment involves using interviews, questionnaires, and rating scales to obtain information on the target behaviour from the person exhibiting the behaviour or from others. With direct assessment, a person observes and records the target behaviour as it occurs. To observe the target behaviour, the observer must be in close proximity to the person exhibiting the behaviour. In addition, the observer must have a precise definition of the target behaviour so that its occurrence can be distinguished from occurrences of other behaviours. Direct assessment usually is more accurate than indirect assessment. Usually because the }Z]Z]L}LZ}Z ]] oo}Z:L] ZZZZKLLZ}L}o[Z memories. Direct assessment methods for observing and recording the target behaviour in a behaviour modification program include the following steps: o Defining the target behaviour o Determining the logistics of recording o Choosing a recording method o Choosing a recording instrument Defining the Target Behaviour The first step is to define the target behaviour. You must identify exactly what the person says of does that constitutes the behavioural excess or deficit targeted for change. The behavioural definition uses active verbs, it is objective and unambiguous. It does not refer to an internal state (e.g. angry, happy, sad, etc) because such internal states cannot be observed and recorded by another person. @Z}7ZZ]}o]L]]}L}ZL}Kl]LL Z}Z}L[Z]LL]}LZ: Labels are not used.

When two people independently observe the same behaviour and both record that the behaviour occurred, this is called interobserver reliability (IOR) or interobserver agreement. www.notesolution.com
