Which method is most effective for demonstrating the success of an intervention strategy?

• A. Reviewing the results of standardized assessment instruments
• B. Utilizing a single-subject design (ABAB) or a reversal procedure (ABA)
• C. Utilizing the subjective, objective, assessment, and plan (SOAP) format
• D. Requesting that a colleague reevaluate the client

Answer: (B)

Utilizing a single-subject design (ABAB) or a reversal procedure (ABA) is considered the most effective method for demonstrating the success of an intervention strategy because it provides a reliable framework for assessing changes in an individual's performance over time in a controlled manner. This research design allows clinicians to observe the effects of an intervention by alternating between the treatment (B phase) and baseline conditions (A phase). By implementing the intervention and then withdrawing it, a therapist can accurately determine whether any observed changes are indeed a result of the intervention itself rather than other external factors. This design is particularly powerful as it emphasizes the individual's response to the treatment, offering clear visual data on trends and patterns of behavior or performance. In contrast, reviewing the results of standardized assessment instruments can provide useful baseline data and comparison metrics but may not capture the dynamic changes on a single-subject level. The SOAP format offers a structured way to document client interactions and progress but does not specifically measure effectiveness through a systematic intervention evaluation. Requesting a colleague to reevaluate the client may bring in a fresh perspective but does not provide the systematic and controlled observation that an ABAB design does. Therefore, the single-subject design stands out as the most effective approach in demonstrating the success of an intervention
