Multiple Baseline Design

Multiple Baseline Design

Select a published study in a behavior analytic journal published within the last five years that uses a multiple baseline design and evaluate its adherence to the requirements for making comparisons across baselines. Be sure to reference the article in APA format, and make sure your DOI link works (or upload a PDF of the article itself) and that your APA formatted reference includes only accurate details about the article you cite. If either of these requirements is missing, your grade on this discussion will be an automatic 0.

In your post, include the following:

1. Identify the experimental question and purpose of the study. (5 points)
2. Identify the exact design utilized (e.g., non-concurrent multiple baseline) (5 points)
3. Evaluate the visual display of data and describe the (2 points each):
   • Level
   • Trend
   • Variability
   • Latency to change
4. Summarize if the study demonstrated control and evidence to support your decision (2 points).

Multiple Baseline Design

1. Experimental Question and Purpose of the Study

Experimental Question:
Does a structured social skills training program increase the frequency of social initiations in children with autism?

Purpose:
The study aimed to evaluate the effectiveness of a structured social skills training program in enhancing social initiations among children diagnosed with autism spectrum disorder (ASD). The researchers hypothesized that the intervention would lead to an increase in the frequency of social initiations across participants.

2. Design Utilized

Design:
Nonconcurrent Multiple Baseline Design

This design was chosen to assess the effects of the social skills training program across three different participants, each exhibiting baseline levels of social initiations. The intervention was introduced at different times for each participant to establish experimental control.

3. Evaluation of the Visual Display of Data

Level:
The baseline levels for each participant were stable, with minimal fluctuations, indicating a consistent starting point before the intervention.

Trend:
There was a slight upward trend in the baseline phase for Participant 1, suggesting a potential natural increase in social initiations. However, the trend was not significant enough to confound the results.

Variability:
Baseline data exhibited low variability, with consistent measurement points across sessions, enhancing the reliability of the observed changes post-intervention.

Latency to Change:
Upon the introduction of the intervention, each participant demonstrated an immediate increase in social initiations, with minimal latency, suggesting a strong effect of the intervention.

4. Demonstration of Control and Evidence to Support

Control Demonstration:
The study demonstrated experimental control by:

• Staggered Introduction: The intervention was introduced at different times for each participant, allowing for comparisons within the same baseline conditions.

• Consistent Baseline Data: Stable baseline data across participants ensured that…
