PSYB45: LECTURE 9
Dealing with Behavioural Data
Behavioural Assessment
Collection and analysis of data
Four purposes:
Identify and describe target behaviour
Identify possible causes of the behaviour
Select appropriate treatment strategy
Evaluation of treatment outcome
Four phases of behaviour modification programs:
Screening or intake
Baseline
Treatment
Follow-up
1) Screening or intake phase:
Collect basic information
Determine appropriateness of services
Discuss rules and procedures with clients
Crisis screening
Which behaviour to focus on?
2) Baseline phase:
Determine the level of target behaviour prior to treatment intervention
oDifferent assessment procedures for collecting baseline information
Indirect
Direct
Experimental
Computer-assisted
- Indirect assessment procedures
Interviews
Questionnaires
Numerous types (e.g., behavioural checklists)
Role-playing
Information from other professionals
Client self-monitoring eg. personal diaries (mood diary)

oAdvantages of indirect assessment procedures:
Convenient
Can provide information about covert procedures
oDisadvantages of indirect assessment procedures:
Relies on accurate memory
Data can be inaccurate, biased
- Direct assessment procedures
Direct observation of behaviour
oMain advantage of direct assessment procedures:
Accuracy - more accurate than indirect assessment
oDisadvantages of direct assessment procedures:
Time consuming
Resource intensive (training required)
Cannot capture covert behaviours

- Experimental assessment procedures
Examine factors that control and maintain problem behaviour
Functional analysis
- Computer-assisted data collection
3) Treatment phase:
Design treatment program
Apply the program
Measure/monitor behaviour regularly
4) Follow-up phase:
Determine whether improvements are maintained
(general notes for behavioural assessment)
Collection of accurate behavioural data can be very important for numerous reasons. For example:
Confirming there actually is a problem
Aid with treatment planning
Assess whether behaviour change is occurring
Reactivity - Simply tracking/recording behaviour can lead to behaviour change
Direct Behavioural Assessment
Characteristics that may be assessed:
Topography
Amount
Intensity
Stimulus control
Latency
Quality
Topography
oThe specific movements involved in a particular response
oNeed specific guidelines (e.g., pictures, descriptions) to help record aspects of topography
