  1. Behavioral Assessment Lesson 8

  2. Behavioral Assessment • Measuring target behavior • Requires detailed behavioral definition • Quantifiable • Unambiguous (objective) • Hi inter-rater reliability • Purpose • Determine if treatment necessary • Aids in choosing treatment approach • Establishes baseline • Indicates change in target behavior ~

  3. Assessment Strategies • Direct assessment • Observe/record B as it occurs • Usually more accurate • Indirect assessment • Relies on observers memory • Questionnaires, interviews, rating scales • Continuous recording • Low frequency behaviors • Time sample recording • Hi frequency behaviors ~

  4. Assessment Methods • Type: Label  behavioral definition • Arm biting  closure of upper & lower teeth on any portion of skin from fingers to elbow • Face-hitting  audible contact of open or closed hand against face or head • Timing • Duration: how long behavior occurs • Latency: delay until behavior occurs ~

  5. Assessment Methods • Frequency • Number of occurrence during specified time period • Percentage of opportunities • e.g., compliance with request • Child complies 11/22 or 50% • Product recording (indirect) • e.g. # completed homework • # problems completed • Uncertainty: who completed B? ~

  6. Objective Measurement • Example: Reduce smoking • Form • # of packs, cigarettes, or puffs? • practical choice of measurement • Frequency • ratio of count & length of observation • Timing • duration of behavior ~

  7. Objective Measurement • Other useful measures • % of task completed • groups: # or % of people completing task • rating scales: qualitative behaviors • Use combination of scales • No predetermined scale for a behavior •  quality of social contacts, not number • or vice versa • depends on individual’s goals ~

  8. Recording Instruments • To record data • Immediately • Practical method • Checklists • Notebooks • ABC Diaries, etc. • Stopwatch, timers • Golf stroke counters • Smart phones ~

  9. ABC Diary for Child’s Tantrums •  behavioral excesses: split B column • Deceleration B, acceleration B ~

  10. Reactivity • Observing B  changes B •  inaccurate functional analysis? • Person knows they are being observed • Wait until accustomed to observer • Hidden observation • Self-monitoring • Sometimes part of treatment • Still important to establish baseline ~
