The feedback sandwich, a widely recommended practice in management and education, involves delivering corrective feedback between two layers of positive feedback. Despite its ubiquity in professional development literature, the empirical basis for this approach has been surprisingly thin. This course examines research by Henley and DiGennaro Reed (2015) that investigated the efficacy of feedback sequence and timing on performance, providing behavior analysts with an evidence-based perspective on a practice many use daily.
For behavior analysts, feedback delivery is not a peripheral concern but a core professional competency. Whether supervising RBTs, training parents, consulting with teachers, or managing clinical teams, the way feedback is structured directly affects the behavior of the recipient. Given that the BACB requires ongoing supervision and that effective feedback is the primary mechanism through which supervisors shape supervisee behavior, understanding the science behind feedback delivery is essential.
The feedback sandwich typically follows a positive-corrective-positive (PCP) sequence. The rationale is intuitive: beginning and ending with positive statements softens the impact of the corrective feedback, maintains the relationship, and keeps the recipient motivated. However, from a behavior-analytic perspective, this rationale raises several concerns. Does embedding corrective feedback between positive statements actually enhance its effectiveness? Could the positive statements function as conditioned reinforcers that inadvertently reinforce the very behaviors that need correction? Does the sequence create a predictable pattern that reduces the salience of any component?
The clinical significance of this topic extends across every setting where behavior analysts practice. In clinical supervision, ineffective feedback can lead to skill deficits that ultimately affect client outcomes. In organizational behavior management (OBM), feedback is the primary intervention for improving employee performance. In parent training, how practitioners deliver feedback to caregivers directly influences their adoption and maintenance of behavior-analytic strategies.
This research contributes to a broader conversation within organizational behavior management about evidence-based supervision practices. As the field of behavior analysis grows and the demand for qualified supervisors increases, the need for empirically supported supervision strategies becomes more pressing. This course equips practitioners with the knowledge to evaluate their own feedback practices and make data-driven decisions about how to structure the feedback they deliver.
The timing dimension of feedback is equally important. Research in OBM has consistently demonstrated that immediate feedback is more effective than delayed feedback, but practical constraints often make immediate delivery challenging. Understanding the interaction between timing and sequence helps practitioners optimize their feedback practices within the constraints of real-world settings.
The feedback sandwich has roots in management and communication literature dating back several decades. It became a staple of supervisory training programs across industries, including healthcare, education, and business. The underlying assumption is that corrective feedback is inherently aversive and that pairing it with positive feedback reduces its aversive properties, thereby maintaining the recipient's motivation and the quality of the supervisor-supervisee relationship.
From a behavior-analytic perspective, this assumption warrants scrutiny. Corrective feedback functions as a form of error correction, signaling a discrepancy between current performance and a desired standard. Whether this signal functions as a punisher depends on the individual's history and the context in which feedback is delivered. For some individuals, corrective feedback may function as an informational stimulus that occasions improved performance. For others, it may function as a conditioned punisher that evokes escape or avoidance behavior.
Organizational behavior management, the subfield of behavior analysis concerned with performance in organizational settings, has a rich literature on feedback. Research has demonstrated that feedback is most effective when it is specific, immediate, frequent, and delivered in a context where the recipient has the skills and resources to change their behavior. The question of sequence, however, has received less empirical attention.
Henley and DiGennaro Reed (2015) conducted their study with undergraduate participants performing a computer task, systematically manipulating both the sequence (positive-corrective-positive versus corrective only) and the timing (immediate versus delayed) of feedback. This controlled experimental approach allowed them to isolate the effects of these variables on performance.
The study's design reflects the strengths of behavior-analytic research: direct measurement of behavior, manipulation of independent variables, and within-subject comparisons. This stands in contrast to much of the management literature on the feedback sandwich, which relies heavily on self-report measures, satisfaction surveys, and theoretical arguments rather than direct measures of performance change.
The broader context for this research includes growing recognition within behavior analysis that supervision practices should be evidence-based rather than tradition-based. The BACB's emphasis on supervision quality, as reflected in the Ethics Code and the supervision requirements for certification, creates a professional mandate for supervisors to use effective feedback strategies. This research directly informs that mandate by providing empirical data on a common but empirically unsupported practice.
The study also connects to literature on verbal behavior in organizational settings. Feedback, from a behavior-analytic perspective, is verbal behavior that functions to alter the behavior of the listener. The sequence and timing of that verbal behavior affect its function, just as the sequence and timing of other antecedent and consequent stimuli affect the behavior they control.
The findings from this research have immediate and practical implications for behavior analysts across all practice settings. The central takeaway is that the feedback sandwich does not appear to enhance performance beyond what corrective feedback alone achieves, and in some cases may actually dilute the effectiveness of the corrective component.
For clinical supervisors, this means reconsidering the routine use of the feedback sandwich in supervision sessions. Many supervisors have been trained to use the PCP sequence and may feel uncomfortable delivering corrective feedback without a positive buffer. However, the research suggests that this discomfort may be more about the supervisor's own avoidance behavior than about the needs of the supervisee. Supervisees who are committed to professional growth often prefer clear, direct feedback that helps them improve rather than feedback that is embedded in a sequence that may obscure the critical message.
This does not mean that positive feedback should be eliminated. Positive feedback remains one of the most powerful tools for shaping and maintaining desired behavior. The key distinction is between using positive feedback contingently to reinforce specific desirable behaviors and using it noncontingently as a buffer around corrective feedback. Contingent positive feedback is a reinforcement operation; buffering positive feedback in a sandwich may function more as a social nicety that does not systematically strengthen any specific behavior.
The timing dimension has equally important implications. Immediate feedback consistently outperforms delayed feedback in the research literature, and this study adds further support to that finding. For supervisors who observe performance in real time, such as during direct observation of therapy sessions, delivering feedback as close to the observed behavior as possible maximizes its effectiveness. This argues for in-session feedback and coaching models over delayed feedback delivered only during weekly supervision meetings.
In parent training contexts, these findings suggest that behavior analysts should model direct, specific feedback when teaching parents to implement behavior plans. Rather than softening corrective feedback about implementation errors, practitioners can provide clear, specific information about what needs to change and how. This approach respects parents as capable adults who can handle direct feedback and avoids the patronizing tone that the feedback sandwich can sometimes create.
In organizational settings, these findings align with the broader OBM literature emphasizing the importance of specific, performance-based feedback. Managers and supervisors who rely on the feedback sandwich may be inadvertently reducing the clarity and impact of their corrective feedback. Training supervisors to deliver direct, respectful corrective feedback alongside separate, contingent positive feedback may produce better performance outcomes.
One important nuance is that the effectiveness of any feedback strategy depends on the quality of the supervisor-supervisee relationship. Corrective feedback delivered in the context of a trusting, supportive relationship is likely to be received differently than the same feedback delivered in a punitive or adversarial context. The research does not suggest that supervisors should be cold or uncaring in their feedback delivery, but rather that the structure of the feedback sandwich is not the mechanism through which relationship quality is built.

The delivery of feedback in supervisory and clinical contexts is governed by several provisions of the BACB Ethics Code for Behavior Analysts (2022), and behavior analysts have an ethical obligation to ensure that their feedback practices are effective, respectful, and grounded in evidence.
Code 4.05 (Maintaining Supervision Documentation) requires behavior analysts to document their supervision activities. While this code addresses documentation rather than feedback strategy directly, it underscores the expectation that supervision is a systematic, accountable process. Using evidence-based feedback strategies is consistent with the broader expectation that supervision be conducted professionally and effectively.
Code 4.07 (Incorporating and Addressing Diversity) requires supervisors to be sensitive to cultural and individual differences. Feedback delivery is an area where cultural responsiveness is particularly important. Some individuals and cultural groups may perceive direct corrective feedback as disrespectful, while others may view the feedback sandwich as patronizing or insincere. Supervisors must assess the preferences and histories of their supervisees and adjust their feedback approach accordingly, using the research evidence as a starting point rather than a rigid prescription.
Code 1.10 (Awareness of Personal Biases and Challenges) is relevant because supervisors' feedback practices are often influenced by their own comfort level with delivering corrective feedback. A supervisor who avoids direct corrective feedback because of their own discomfort with conflict is allowing personal bias to interfere with their professional responsibility. Awareness of this tendency, combined with the evidence that direct feedback can be equally or more effective, can help supervisors overcome avoidance patterns.
Code 2.01 (Providing Effective Treatment) extends to supervision because the quality of supervision directly affects client outcomes. If a supervisor uses an ineffective feedback strategy that fails to correct skill deficits in supervisees, the ultimate impact falls on the clients those supervisees serve. The ethical obligation to provide effective treatment therefore encompasses an obligation to use effective supervision strategies, including evidence-based feedback delivery.
Code 4.01 (Compliance with Supervision Requirements) requires behavior analysts to meet the BACB's supervision standards. While this code does not specify particular feedback strategies, it establishes the professional expectation that supervision be competent and thorough. Relying on a feedback strategy with limited empirical support, when more effective alternatives are available, could be seen as falling short of this standard.
Code 2.18 (Continual Evaluation of the Behavior-Change Program) applies analogously to supervision. Just as behavior analysts must evaluate and modify intervention programs based on data, they should evaluate and modify their supervision practices based on evidence. If data suggest that the feedback sandwich is not producing the desired changes in supervisee behavior, the supervisor should adjust their approach.
There is also an ethical dimension related to informed consent and transparency. Supervisees have a right to know how their supervision will be conducted and to provide input on the approach. Being transparent about feedback strategies, including the evidence behind them, respects supervisee autonomy and models the evidence-based decision-making that supervisors expect from their supervisees.
Effective feedback delivery requires behavior analysts to assess multiple variables before deciding on a feedback strategy. A decision-making framework for feedback should consider the characteristics of the recipient, the nature of the performance being addressed, the context in which feedback will be delivered, and the data on the effectiveness of the chosen approach.
The first assessment dimension is the supervisee's or trainee's current skill level and learning history. Novice practitioners who are still acquiring basic skills may benefit from a higher ratio of positive to corrective feedback, not because corrective feedback is harmful but because the frequent errors that characterize early skill acquisition create many opportunities for correction that, without balancing positive feedback, may make the supervision context aversive. For advanced practitioners, direct corrective feedback may be more efficient and more respectful of their competence.
The second dimension is the nature of the performance error. Critical errors that affect client safety or welfare require immediate, clear corrective feedback regardless of the broader feedback strategy. In these cases, embedding corrective feedback in a sandwich may delay the corrective message and reduce its urgency. For minor errors or areas for refinement, the approach can be more flexible.
The third dimension is the context and timing. Feedback delivered during a therapy session (in vivo) has different constraints than feedback delivered in a post-session debriefing. In vivo feedback must be brief and clear to minimize disruption. Post-session feedback can be more detailed and discussion-oriented. The research on timing suggests that in vivo feedback, when feasible, should be prioritized because of the closer temporal proximity between behavior and feedback.
The fourth dimension is the relationship between the supervisor and the supervisee. Assessment of this relationship should be ongoing. Signs that the relationship is strained, such as avoidance behavior by the supervisee, emotional responses to feedback, or declining performance after feedback sessions, may indicate that the feedback approach needs adjustment. However, these signs should be interpreted carefully, as they may also reflect other variables such as workload stress or personal issues.
Data collection on feedback effectiveness should be built into the supervision process. This can include direct measures of supervisee performance following feedback (did the targeted behavior change?), supervisee self-report on the helpfulness of feedback (with appropriate caveats about self-report validity), and supervisor self-monitoring of their own feedback practices. Regular review of these data allows supervisors to make informed adjustments to their approach.
A practical decision-making protocol might proceed as follows: Observe supervisee performance and identify specific behaviors to address. Determine the urgency and severity of any performance gaps. Deliver corrective feedback as close to the observed behavior as possible, using specific, behavioral language. Deliver positive feedback separately and contingently on specific desirable behaviors. Collect data on supervisee performance following feedback. Review data periodically and adjust the feedback approach based on outcomes.
This protocol is consistent with the broader behavior-analytic emphasis on data-driven decision-making and avoids the assumption that any single feedback strategy is universally effective.
The practical implications of this research are straightforward and actionable. If you have been using the feedback sandwich as your default supervisory strategy, the evidence suggests you may want to reconsider.
First, separate your positive and corrective feedback. Rather than embedding corrective feedback between positive statements, deliver positive feedback contingently when you observe desirable behavior and deliver corrective feedback directly when you observe errors. This ensures that each type of feedback maintains its function without one diluting the other.
Second, prioritize immediacy. The closer your feedback is to the behavior it addresses, the more effective it will be. If you currently rely primarily on weekly supervision meetings for feedback delivery, consider incorporating more in-the-moment feedback through observation and coaching.
Third, be specific. Both positive and corrective feedback should reference specific, observable behaviors. Telling a supervisee that they did a great job is less effective than telling them that their prompting hierarchy during the discrete trial session was perfectly executed. Similarly, telling a supervisee to do better is less effective than telling them that their inter-trial interval was too long and providing a specific target.
Fourth, monitor the outcomes. Track whether your feedback is actually changing behavior. If a supervisee continues to make the same error after repeated feedback, the issue may not be the content of the feedback but its delivery, timing, or the supervisee's skill deficits that require additional training.
Finally, remember that the goal of feedback is behavior change, not comfort. While maintaining a respectful and supportive supervisory relationship is important, the primary purpose of feedback is to improve performance. Evidence-based feedback strategies serve both the supervisee's professional development and the welfare of the clients they serve.
