Reliability and validity of observation
- Reliability of observation : Complexity of target behavior and training observers
- Validity of observation : mechanics of rating, observer error, reactivity, ecological validity
Behavioral Assessment
- SORC Model ( Kanfer and Philips, 1970 )
- Stimulus ( S )
- Organism ( O )
- Response ( R )
- Consequence ( C )
- Functional analysis ( ABC Model ) ( Skinner, 1953 )
- Antecedent event ( A )
- Behavior ( B )
- Consequence (C )
Two broad categories of behavior
- Responders : are the antecedent – controlled behaviors which function in a reflexive manner : Somatic reflexes, Emotional reactions and other responsesof the smooth muscles, gland and heart , and sensations
- Operants : are consequence – controlled : Actions, Instrumental responses of the smooth muscles, gland and cognitions
Assessment task
- Identify : respondent, operant, consequence of operant, setting event
- Classify : Behavioral excesses, behavioral deficits, behavioral anomalies, behavioral assets
- Prophesy : Theoretical orientation
- Specify : recommendations : precise goals, method of interventions, therapeutic agents
- Evaluation : What changes are occurring in behavior treatment : processes evaluation, outcome evaluation, follow up evaluation
Methods of behavioral assessment
- Behavioral interview
- Direct observation
- Psycho – Physiological measures
- Behavioral inventories and checklist
- BDI, CBCL
Behavioral sampling
- Event sampling
- Duration sampling
- Time sampling
- Interval sampling
- Subject sampling
- Situation sampling
