  1. AB Design
    used in single-case evaluation. A-baseline phase and B-intervention phase
  2. ABAB withdrawal/reversal design
    used in single-case evaluation. if intervention was cause of improvement then in the second baseline phase target problem will be similar to original baseline. When intervention is reintroduced target problem should improve again
  3. baseline
    phase in single-case evaluation. repeated measure of a target problem before new intervention or policy is introduced
  4. generalization of effects
    occurs when intervention affects behaviors in addition to the target behavior
  5. multi-baseline design
    a type of single-case veal.- attempts to control for variables by having multiple baseline and intervention phases
  6. operational definition
    concrete and specific definition of something in terms of operations- can be observed and categorized
  7. reactivity
    a process in which change in a dependent variable in induced by the research procedures
  8. replication
    repeating study to reduce error. duplication of withdrawal or reintroduction of an intervention to hep increase internal validity
  9. self-reports scale
    subjects all respond to the some list of written questions. specifically designed to measure a particular construct
  10. single-case evaluation
    time-series design used to evaluate the impact of an intervention or policy change on individual cases
  11. triangulation
    the use of more than one imperfect data-collection alternative in which each option is vulnerable to different potential sources of error
