What is a Multiple Baseline Design? | Guide
In the realm of behavioral research, a robust methodology often bridges the gap between theoretical understanding and practical application, and the American Psychological Association emphasizes the importance of rigorous experimental designs. Understanding what is a multiple baseline design is crucial for professionals aiming to evaluate the effectiveness of interventions across different subjects, settings, or behaviors. This approach becomes particularly relevant when randomized controlled trials are not feasible or ethical. The core strength of the multiple baseline design lies in its ability to demonstrate a functional relationship without the need for a control group. A prominent figure, such as Donald Baer, significantly contributed to the establishment and popularization of single-subject research methodologies, which include the multiple baseline design. Researchers often use specific data analysis software to visually and statistically analyze the effects of the interventions implemented across these baselines.
Multiple baseline designs are a cornerstone of single-case research methodology, particularly valuable in applied settings where the rigorous control of traditional group designs is impractical or unethical. But what exactly is a multiple baseline design?
At its core, it's an experimental approach used to demonstrate a functional relationship between an intervention and a target behavior across multiple baselines. These baselines can represent different behaviors, individuals, or settings.
Purpose and Functionality
The primary purpose of a multiple baseline design is to evaluate the effectiveness of an intervention in a real-world context. Instead of randomly assigning participants to treatment or control groups, the intervention is systematically introduced across different baselines at staggered points in time.
This staggered introduction is the key to demonstrating experimental control, showing that behavior change coincides with the introduction of the intervention and not some extraneous variable.
Significance in Applied Behavior Analysis (ABA)
In the field of Applied Behavior Analysis (ABA), the multiple baseline design holds particular significance. ABA focuses on applying principles of behavior to improve socially significant behaviors, and often operates in applied settings such as schools and clinics.
Multiple baseline designs provide a practical and ethical means of evaluating the impact of behavioral interventions on individuals in these settings.
The design allows practitioners to systematically introduce interventions and collect data on their effectiveness without withholding potentially beneficial treatments from any individual for an extended period.
Addressing Practical and Ethical Concerns
One of the most appealing aspects of the multiple baseline design is its ability to address practical and ethical concerns often encountered in applied research. By staggering the introduction of the intervention, every participant eventually receives the treatment.
This addresses the ethical concern of withholding a potentially effective intervention from a control group.
Furthermore, the staggered implementation is often more feasible in real-world settings where logistical constraints may make simultaneous intervention impossible. This makes the multiple baseline design a pragmatic choice for researchers and practitioners alike.
The staggering across baselines also aids in isolating the effect of the intervention, as changes in behavior are expected to occur only after the intervention is introduced to that specific baseline. This helps to rule out confounding variables and strengthens the evidence for a causal relationship.
Core Concepts and Principles of Multiple Baseline Designs
Multiple baseline designs are a cornerstone of single-case research methodology, particularly valuable in applied settings where the rigorous control of traditional group designs is impractical or unethical. But what exactly is a multiple baseline design?
At its core, it's an experimental approach used to demonstrate a functional relationship between an intervention and a behavior, across multiple baselines. This section explores the fundamental concepts and principles that make this design so powerful.
Understanding Baseline Logic
Baseline logic is the bedrock upon which multiple baseline designs are built. It provides a systematic framework for determining whether an intervention is truly responsible for changes in behavior. This framework is based on three key elements: prediction, verification, and replication.
Prediction
Prediction involves anticipating the future pattern of the data if no intervention were to occur. We establish a baseline, a period of observation without the intervention, to determine the typical level and trend of the target behavior.
This baseline then allows us to predict what the behavior would look like in the future if conditions remained unchanged. A stable baseline is crucial for making accurate predictions.
Verification
Verification is the process of confirming that the behavior only changes when the intervention is applied. We strategically introduce the intervention across different baselines at different times.
If the behavior in a given baseline changes only after the intervention is introduced, and not before, this provides evidence that the intervention is responsible for the change. This verifies our initial prediction that the behavior would remain stable without intervention.
Replication
Replication strengthens the evidence for a functional relationship by repeating the effect across multiple baselines. When the intervention consistently produces similar behavior changes across different behaviors, participants, or settings, it demonstrates the reliability and generalizability of the findings.
Replication is critical for establishing a robust cause-and-effect relationship and minimizing the possibility that extraneous factors are responsible for the observed changes.
Establishing a Functional Relationship
The ultimate goal of a multiple baseline design is to establish a functional relationship between the independent variable (IV), which is the intervention, and the dependent variable (DV), which is the target behavior. This means demonstrating that the IV directly causes changes in the DV.
Independent and Dependent Variables
The independent variable is the intervention being evaluated. It is what the researcher manipulates. For example, it could be a specific teaching strategy, a new therapy technique, or a behavioral management protocol.
The dependent variable is the behavior being measured. It's what we expect to change as a result of the intervention. The DV must be clearly defined and measurable, allowing for objective data collection.
Ruling Out Extraneous Variables
Establishing a functional relationship requires ruling out extraneous variables. These are factors other than the intervention that could potentially influence the dependent variable.
Careful planning, consistent implementation of the intervention, and close monitoring of the environment are essential for minimizing the impact of extraneous variables and strengthening the evidence for a causal relationship.
Ensuring Experimental Control
Experimental control is the extent to which the researcher can confidently conclude that the independent variable is directly responsible for the observed changes in the dependent variable.
This is achieved by systematically manipulating the IV and demonstrating that the DV changes only when the IV is applied, while also controlling for extraneous variables.
Achieving Internal Validity
A high degree of experimental control leads to high internal validity. Internal validity refers to the extent to which a study's findings are trustworthy and accurately reflect the relationship between the IV and the DV.
Without strong internal validity, it's impossible to confidently conclude that the intervention caused the observed behavior change.
The Importance of Treatment Fidelity
Treatment fidelity, also known as implementation fidelity, refers to the degree to which the intervention is implemented as planned. It's crucial to ensure that the intervention is delivered consistently and accurately across all baselines and throughout the duration of the study.
Failing to maintain treatment fidelity can compromise the internal validity of the study, making it difficult to determine whether the intervention was truly effective.
By understanding and adhering to these core concepts and principles, researchers and practitioners can effectively use multiple baseline designs to evaluate the effectiveness of interventions and improve outcomes in a variety of applied settings.
Key Components of a Multiple Baseline Design
Multiple baseline designs are a cornerstone of single-case research methodology, particularly valuable in applied settings where the rigorous control of traditional group designs is impractical or unethical. But what exactly makes up a multiple baseline design? Let’s break down the core components that are essential for understanding and implementing this powerful research tool, focusing on the dependent variable, independent variable, and the crucial concept of baselines.
Understanding the Dependent Variable (DV)
The dependent variable (DV) is the heart of your research, acting as the target behavior you aim to change through your intervention. It must be a clearly defined and, crucially, measurable behavior.
This clarity ensures that any changes observed can be reliably attributed to the intervention, rather than to ambiguity in defining the behavior itself.
Examples of Dependent Variables
Consider these examples across different settings:
-
Schools: A dependent variable might be the number of math problems a student correctly completes in a 30-minute period, or the frequency of disruptive behaviors like calling out in class.
-
Clinics: Here, the DV could be the number of self-injurious behaviors exhibited by a client during a therapy session, or the level of anxiety reported on a standardized anxiety scale.
-
Homes: In-home settings, the DV could be the amount of time a child spends engaging in cooperative play with siblings, or the frequency of completing assigned chores without prompting.
Defining the Independent Variable (IV)
The independent variable (IV) represents the intervention you're evaluating. It's what you manipulate to see if it has an effect on the dependent variable. The success of a multiple baseline design hinges on a well-defined IV.
The Importance of Operational Definitions
It’s crucial to have a precise operational definition of your intervention. This means describing the intervention in specific, observable, and measurable terms.
For example, instead of simply stating "a social skills intervention," specify the exact components of the intervention, such as "a 30-minute social skills training session involving role-playing, feedback, and positive reinforcement, conducted three times per week."
This level of detail ensures that the intervention is implemented consistently across all baselines and allows for replication by other researchers.
The Critical Role of Baselines
Baselines are the foundation upon which the effects of your intervention are evaluated. They involve the concurrent measurement of multiple behaviors, participants, or settings before the intervention is introduced. Baselines are your primary comparison point.
Staggered Implementation: The Key to Control
The hallmark of a multiple baseline design is the staggered implementation of the intervention across these baselines. This means that the intervention is introduced at different points in time for each baseline.
For example, in a multiple baseline design across behaviors, you might start an intervention to increase on-task behavior in week 1, then start an intervention to improve assignment completion in week 3, and finally, start an intervention to reduce disruptive behavior in week 5.
This staggered approach allows you to demonstrate that changes in the dependent variable are indeed caused by the intervention, rather than by extraneous factors that might be present at a particular point in time. The baselines thus act as controls for each other.
Types of Multiple Baseline Designs: A Comprehensive Overview
Multiple baseline designs are a cornerstone of single-case research methodology, particularly valuable in applied settings where the rigorous control of traditional group designs is impractical or unethical. But what exactly are the different types of multiple baseline designs? Let’s break down the core types, each offering a unique approach to evaluating intervention effectiveness.
Multiple Baseline Across Behaviors
This design is employed when the focus is on changing multiple behaviors within the same individual. The intervention is sequentially introduced to each behavior, allowing researchers to assess whether the intervention, rather than extraneous factors, is responsible for the observed changes.
Application and Examples
Imagine a scenario where a student needs to improve several academic skills.
For example, you may be working with a student that needs to improve on their reading fluency, writing proficiency, and mathematical problem-solving. The intervention (e.g., a targeted tutoring program) is first applied to reading fluency while the other behaviors remain in the baseline phase.
Once a stable change is observed in reading, the intervention is then applied to writing, and finally to math. If each behavior improves only after the intervention is applied, a functional relationship between the intervention and behavior change is demonstrated.
Advantages of Across Behaviors Designs
One of the primary advantages of this design is its ability to demonstrate that the changes are specific to the introduced intervention and not due to other variables.
It’s also very flexible and can be tailored to address a variety of issues.
Multiple Baseline Across Participants
In this design, the same intervention is applied to the same target behavior across multiple individuals. The intervention is introduced at different times for each participant.
This staggered introduction helps to rule out extraneous variables that might be influencing behavior.
Real-World Scenarios
For instance, you might be evaluating a new social skills intervention for several children diagnosed with autism spectrum disorder.
Each child begins with a baseline phase measuring their social interactions.
The intervention is then introduced sequentially to each child.
If improvements in social skills are observed only after the intervention is introduced for each child, this provides strong evidence that the intervention is effective.
Participant Selection
Selecting participants with similar baseline levels of behavior is crucial for this design to be effective.
This helps ensure that the comparison across individuals is meaningful.
Multiple Baseline Across Settings
This design is implemented when the goal is to change a specific behavior across different environments or contexts. The intervention is introduced in each setting at different points in time.
Examples and Implementation
Consider a scenario where a classroom management strategy is being implemented to reduce disruptive behaviors.
This can be implemented in different classrooms in a school.
The strategy might first be introduced in one classroom, while the other classrooms remain in the baseline phase.
Once a stable change is observed in the first classroom, the intervention is then implemented in the next classroom, and so on.
This staggered approach helps to determine if the intervention is effective across various settings and not influenced by setting-specific factors.
Contextual Considerations
When using this design, it’s important to consider the characteristics of each setting. For instance, the physical layout, resources, and the adults in each setting.
Addressing differences in these setting factors can impact the effectiveness of the intervention.
By understanding the nuances of each type of multiple baseline design, researchers and practitioners can choose the most appropriate method for evaluating interventions. This will contribute to evidence-based practice and effective behavior change strategies.
Data Collection and Analysis in Multiple Baseline Designs
Effective data collection and rigorous analysis are paramount for demonstrating the effectiveness of an intervention using a multiple baseline design. These procedures provide the evidence needed to determine whether the intervention truly impacted the target behavior, across individuals, settings, or behaviors. Let's examine the key components of this process, from structured data collection to visual analysis techniques.
Structuring Data Collection Systems
The foundation of any strong multiple baseline design lies in well-organized data collection. A clearly defined and consistently implemented data collection system is essential. This system ensures that observations are recorded accurately and reliably, providing the raw material for subsequent analysis.
Data Collection Sheets and Operational Definitions
Begin by creating structured data collection sheets.
These sheets should include:
- Clearly defined variables.
- The observer's name.
- The date and time of observation.
- Space to record the target behavior and any relevant contextual information.
The target behavior must be operationally defined, specifying exactly what constitutes an instance of the behavior. This reduces ambiguity and enhances inter-observer agreement.
Ensuring Data Reliability
Reliability is the degree to which data collection yields consistent results. To ensure reliability:
- Train all observers thoroughly on the operational definitions and data collection procedures.
- Conduct inter-observer agreement (IOA) checks regularly.
- Aim for an IOA of 80% or higher.
If IOA falls below this threshold, retrain observers and refine the operational definitions as needed.
Visual Analysis: Unveiling Trends and Changes
Visual analysis is the primary method used to interpret data in multiple baseline designs. This involves graphing the data and visually inspecting it for changes in level, trend, and variability that coincide with the introduction of the intervention.
Graphing Data
Create a line graph with:
- The x-axis representing time (e.g., sessions, days, weeks).
- The y-axis representing the measurement of the target behavior (e.g., frequency, duration, percentage).
- Separate data paths for each baseline.
- Vertical lines indicating when the intervention was introduced in each baseline.
Clear labeling of axes and data points enhances the readability and interpretability of the graph.
Analyzing Data Patterns
When analyzing the graph, consider:
- Level: The average value of the data within a phase (baseline or intervention). A change in level indicates an immediate effect of the intervention.
- Trend: The direction of the data path (increasing, decreasing, or stable). A change in trend suggests a gradual effect of the intervention.
- Variability: The degree to which the data points deviate from the mean. Lower variability indicates greater stability in the behavior.
Look for a clear and consistent change in level, trend, or variability that occurs only after the intervention is introduced in each baseline. This strengthens the evidence that the intervention is responsible for the observed changes.
Leveraging Graphing Software
While graphs can be constructed manually, graphing software can streamline the process and produce professional-looking visuals.
Software Options
Many software programs can create graphs suitable for multiple baseline designs.
Some popular options include:
- Microsoft Excel.
- Google Sheets.
- Specialized statistical software (e.g., SPSS, R).
Enhancing Data Presentation
Use the software to:
- Create clear and accurate graphs.
- Label axes and data points appropriately.
- Add annotations to highlight key findings.
- Customize the appearance of the graph for optimal visual appeal.
Ensuring Treatment Integrity
Treatment integrity, also known as treatment fidelity, refers to the extent to which the intervention is implemented as planned. Maintaining high treatment integrity is crucial for ensuring that the observed behavior changes are indeed due to the intervention, and not to variations in its implementation.
Treatment Integrity Checklists
One effective way to monitor treatment integrity is to use treatment integrity checklists. These checklists outline the steps involved in implementing the intervention and provide a means for recording whether each step was performed correctly.
Addressing Deviations
If deviations from the planned intervention are detected, take immediate steps to:
- Correct the implementation.
- Provide additional training to the implementer.
- Document the deviations and their potential impact on the results.
By systematically collecting and analyzing data, and by ensuring high treatment integrity, you can draw valid and reliable conclusions about the effectiveness of your intervention. This will provide valuable insights for improving outcomes in applied settings.
Ensuring Validity and Reliability in Your Research
Effective data collection and rigorous analysis are paramount for demonstrating the effectiveness of an intervention using a multiple baseline design. These procedures provide the evidence needed to determine whether the intervention truly impacted the target behavior, across individuals, settings, or behaviors. However, strong methodology goes beyond just data collection. It requires careful attention to validity, reliability, generalization, and treatment fidelity to ensure the credibility and practical significance of the research. Let's explore these crucial elements in detail.
Internal Validity: Establishing Cause and Effect
Internal validity refers to the degree to which a study demonstrates a causal relationship between the intervention (independent variable) and the observed changes in behavior (dependent variable). In simpler terms, it's about confidently concluding that the intervention, and not some other factor, caused the change.
Controlling Confounding Variables
Confounding variables are extraneous factors that could potentially influence the outcome of your study. These variables can threaten internal validity by providing alternative explanations for the observed behavior changes.
Carefully controlling or accounting for potential confounders is essential. This might involve:
-
Using standardized procedures.
-
Randomly assigning participants (when appropriate).
-
Monitoring and documenting any significant events that occur during the study.
By minimizing the influence of confounding variables, we can strengthen the argument that the intervention is responsible for the observed effects.
Demonstrating Causation
In a multiple baseline design, causation is demonstrated by showing that the target behavior changes only after the intervention is introduced across each baseline. The staggered introduction of the intervention is key to ruling out other explanations.
If behavior changes consistently coincide with the intervention across multiple baselines, it provides strong evidence that the intervention is the active ingredient.
Treatment Fidelity: Implementing the Intervention as Planned
Treatment fidelity, also known as intervention fidelity, refers to the extent to which an intervention is implemented as intended. Maintaining high treatment fidelity is critical for ensuring that the observed effects are truly attributable to the intervention.
Monitoring Implementation
Regular monitoring of the intervention's implementation is essential. This can involve:
-
Direct observation of intervention sessions.
-
Self-reports from interventionists.
-
Review of session materials.
Using Treatment Integrity Checklists
Treatment Integrity Checklists are valuable tools for systematically assessing whether the intervention is being delivered as planned. These checklists should include specific steps or components of the intervention and a rating scale to indicate the degree to which each component was implemented correctly.
Using these checklists regularly allows for the identification and correction of any deviations from the planned protocol, thus bolstering treatment fidelity.
Generalization and Maintenance: Extending the Impact
While demonstrating an intervention's effectiveness under controlled conditions is important, it's equally vital to consider its real-world impact. This involves assessing generalization and maintenance.
Generalization
Generalization refers to the extent to which the effects of the intervention extend to other:
- Settings.
- Behaviors.
- Individuals.
For instance, an intervention that improves a student's on-task behavior in the classroom may also lead to improvements in their behavior at home. Measuring behavior changes across different settings can help determine the intervention's broader impact.
Maintenance
Maintenance refers to the durability of the intervention effects over time. Does the behavior change persist even after the intervention is withdrawn?
Assessing maintenance involves follow-up data collection at specified intervals after the intervention has ended. This provides valuable information about the long-term effectiveness of the intervention.
Single-Case Reporting Guidelines: Ensuring Transparency
Adhering to established reporting guidelines is crucial for ensuring the transparency and replicability of single-case research.
Following Established Guidelines
Several sets of guidelines exist for reporting single-case research, such as the Single-Case Reporting Guideline in BEhavioural interventions (SCRIBE). These guidelines provide detailed recommendations for describing:
- Participants.
- Interventions.
- Outcomes.
- Data analysis procedures.
Promoting Replicability
By following these guidelines, researchers can ensure that their studies are clearly and comprehensively reported, making it easier for others to replicate their findings. This is essential for building a robust evidence base for effective interventions.
Applications of Multiple Baseline Designs in Real-World Settings
Effective data collection and rigorous analysis are paramount for demonstrating the effectiveness of an intervention using a multiple baseline design. These procedures provide the evidence needed to determine whether the intervention truly impacted the target behavior, across individuals, settings, or behaviors. Now, let's delve into the practical applications of multiple baseline designs across diverse real-world settings.
Schools: Enhancing Academic and Behavioral Outcomes
Multiple baseline designs are invaluable in educational settings for evaluating a wide range of interventions.
These designs help educators make data-driven decisions, ensuring that interventions are effective and tailored to meet the specific needs of their students.
Improving Academic Performance
One common application is evaluating academic interventions aimed at improving student performance. For example, a researcher might use a multiple baseline design across different academic skills (reading, writing, math) to assess the impact of a new teaching strategy.
By staggering the introduction of the intervention across these skills, researchers can determine whether the teaching strategy is causally related to improvements in each area.
This approach provides strong evidence for the effectiveness of the intervention, as improvements should only occur when the intervention is actively implemented.
Addressing Behavioral Challenges
Multiple baseline designs are also used to address behavioral challenges in schools. Interventions targeting disruptive behaviors, such as classroom rule violations or off-task behavior, can be systematically evaluated using these designs.
For instance, a behavior specialist might implement a positive reinforcement system across different classrooms to assess its impact on reducing disruptive behaviors.
The staggered introduction of the intervention allows for the demonstration of a functional relationship between the reinforcement system and behavior change, thus supporting its efficacy.
Clinics: Evaluating Therapeutic Interventions and Patient Progress
In clinical settings, multiple baseline designs play a crucial role in evaluating the effectiveness of therapeutic interventions and tracking patient progress.
These designs offer a rigorous and ethical approach to assessing the impact of treatments, ensuring that interventions are both effective and beneficial for patients.
Assessing Therapeutic Interventions
Multiple baseline designs can be used to evaluate the effectiveness of therapeutic interventions for various conditions, such as anxiety disorders, depression, and autism spectrum disorder.
For example, a clinician might use a multiple baseline design across different clients to assess the impact of a cognitive-behavioral therapy (CBT) intervention on reducing anxiety symptoms.
By staggering the start of the CBT intervention for each client, the clinician can determine whether the intervention is causally related to improvements in anxiety levels.
Measuring Treatment Progress
Multiple baseline designs are also valuable for measuring progress in treatment and tracking patient outcomes.
These designs allow clinicians to monitor changes in target behaviors or symptoms over time, providing valuable feedback on the effectiveness of the treatment plan.
For instance, a therapist might use a multiple baseline design across different behaviors (e.g., social interaction, communication skills) to assess the progress of a child with autism receiving behavioral therapy.
This approach allows the therapist to track improvements in each behavior as the intervention is implemented, guiding adjustments to the treatment plan as needed.
Home Settings: Enhancing Family Interactions and Behavior Management
Multiple baseline designs are also highly applicable in home settings, where they can be used to evaluate behavioral interventions aimed at improving family interactions and managing challenging behaviors.
These designs empower families to implement evidence-based strategies, ensuring that interventions are effective and tailored to their unique needs.
Evaluating Behavioral Interventions
In the home environment, multiple baseline designs can be used to evaluate the effectiveness of behavioral interventions aimed at addressing various issues, such as non-compliance, aggression, or sleep problems.
For example, a parent might implement a token economy system across different children in the family to assess its impact on improving compliance with household chores.
By staggering the introduction of the token economy for each child, the parent can determine whether the intervention is causally related to improvements in compliance.
Improving Family Interactions
Multiple baseline designs can also be used to improve family interactions by targeting specific communication or interaction patterns.
For instance, a family therapist might implement a structured communication protocol across different family members to assess its impact on reducing conflicts and improving understanding.
This approach allows the therapist to track improvements in communication patterns as the intervention is implemented, fostering a more harmonious family environment.
Hospitals/Healthcare Settings: Optimizing Patient Outcomes and Adherence
In hospitals and healthcare settings, multiple baseline designs are used to evaluate interventions aimed at improving patient outcomes and adherence to medical regimens.
These designs provide a systematic way to assess the impact of interventions, ensuring that healthcare practices are evidence-based and effective.
Improving Patient Outcomes
Multiple baseline designs can be used to evaluate interventions designed to improve various patient outcomes, such as reducing hospital readmissions, improving pain management, or enhancing rehabilitation outcomes.
For example, a hospital might implement a post-discharge support program across different patient groups to assess its impact on reducing readmission rates.
By staggering the implementation of the support program, the hospital can determine whether the intervention is causally related to improvements in patient outcomes.
Measuring Adherence to Medical Regimens
Multiple baseline designs are also valuable for measuring and improving patient adherence to medical regimens, such as medication schedules, dietary guidelines, or exercise programs.
For instance, a healthcare provider might implement a medication reminder system across different patients to assess its impact on improving adherence to medication schedules.
This approach allows the provider to track improvements in adherence as the intervention is implemented, helping patients achieve better health outcomes.

FAQs: Multiple Baseline Design
What makes a multiple baseline design different from other research designs?
Unlike designs that focus on group averages, a multiple baseline design evaluates the impact of an intervention on multiple individuals, behaviors, or settings, one at a time. This sequential introduction helps establish a causal relationship between the intervention and changes in each baseline. In essence, what is a multiple baseline design aims for personalized insights.
How does a multiple baseline design help establish causality?
The staggered introduction of the intervention is key. If behavior only changes after the intervention is applied at each baseline, it suggests the intervention caused that change. This reduces the likelihood that other factors, outside the design, are responsible. This is a major strength of what is a multiple baseline design.
When is it appropriate to use a multiple baseline design?
A multiple baseline design is ideal when you cannot or should not remove an intervention after it's introduced (like in many educational or clinical settings). It is also beneficial when randomly assigning participants to control groups is unethical or impractical. Understanding when to use it is vital to knowing what is a multiple baseline design.
What are some common weaknesses of multiple baseline designs?
It can be time-consuming to collect baseline data across multiple subjects, behaviors, or settings. Also, the success of the design depends on demonstrating independence between the baselines. If the intervention applied in one baseline influences another, the design's validity is weakened. Recognizing these weaknesses is part of understanding what is a multiple baseline design.
So, there you have it! Hopefully, this guide helped demystify what a multiple baseline design is and gave you a better understanding of how it can be a powerful tool in research and practice. Now you can confidently spot it in action or even consider using it yourself when you need a solid way to demonstrate cause-and-effect without a full-blown randomized controlled trial.
