Multiple baseline across settings

Julie & Nicole

Task 1

Multiple Baseline Design Across Settings

~Multiple baseline across settings design: a multiple baseline design in which the treatment variable is applied to the same behavior of the same subject across two or more different settings, situations, or time periods.

~Participant demonstrates target behavior across three or more settings (conditions)

~Select an intervention that is likely to have the same effect across multiple settings

~Settings should be functionally similar but also independent of one another

~Use a consistent measurement procedure for each setting

Task 2

MB Across settings

This graph shows MB Across Settings.

Three baselines were collected in three different settings; home classroom, playground, family home.

All 3 settings were showing impulsive/disruptive behaviors from this particular individual.

The graph also shows the impulsive/disruptive behavior after intervention was implemented.

Task 3

Why use mb across settings?

The multiple-baseline across settings design is particularly well suited to interventions whose objective is to bring about changes in behavior in more than one relevant environment. allows for one or two replications of the original effect (Kazdin, 1994).

Task 4

multiple baseline across settings - Example

Brandon, a 9-year-old diagnosed with attention-deficit disorder, has encountered significant difficulties both at home and at school because of impulsive and disruptive behavior. On the advice of a therapist, a behavioral intervention consisting of time-out and differential reinforcement contingencies is implemented both by Brandon’s teachers at school and by his parents at home. Instances of poor impulse control or disruption of the class or family result in 5-minute time-out periods, and periods of appropriate behavior result in receipt of tokens that can be exchanged for special privileges, toys, snacks, and so on. The behavioral intervention program is implemented in staggered fashion across three different environments: (1) the home classroom and (2) playground at school, and (3) at home.

Task 5

1. The multiple-baseline across settings design is particularly well suited to interventions whose objective is to bring about changes in behavior in more than one relevant environment.

2. valid due to the fact that data is being collected across multiple settings

3. Can be time saving

4. Does not require removal of intervention that is already effective

Task 6

1. Ambiguities can result from the interdependence of the settings that serve as the baselines. Extraneous events might coincide with the application of the intervention and lead to changes in performance. However, it is possible that the intervention accounted for the changes in different settings even though it was only applied in one.

2. The intervention may produce inconsistent effects on the situation/setting to which it is introduced. This means that some behaviors are altered when the intervention is introduced and others are not. The problem with this is that the intervention might be introduced in more than one setting at different times, but only one of the behaviors change.

3. Interventions are applied to the different settings one at a time, eventually it is extended to all baselines. if several settings/situations are included, this might take weeks before the final setting received the intervention. one issue with this is that if the intervention is successful, it is considered unethical to withhold intervention. Also, the withholding of intervention might have an impact on performance changes within the setting before the intervention has even been applied.

4. another limitation would be is if there is only one setting selected for treatment

5. a concern would also be when more than one intervention phase is desirable to demonstrate a functional relation

6. Finally, when constraints on resources make implementation impossible, this brings concerns to the table

Task 8

please go to our discussion board to answer the following question,

as well as find the link to play our kahoot!

can you think of any individuals or students that would benefit from

collecting data and implementing intervention using mb across settings? why?
