Too Close for Comfort: Navigating the Ethics of Dual Relationships Between Supervision, Mentorship, and Friendship

Overview & Clinical Significance

Jamie Redding's presentation addresses one of the most practically challenging dimensions of BCBA supervisory practice: the fact that the supervisory relationship is simultaneously a professional evaluation relationship, a mentorship relationship, and — especially in settings where supervisors and supervisees share professional communities, workplaces, or social networks — often a relationship with meaningful personal dimensions as well. The BACB Ethics Code's guidance on avoiding dual relationships is clear in principle and complicated in practice.

The dual relationship problem in supervision is not primarily about obvious violations — the supervisor who enters a romantic relationship with a supervisee or who employs a family member in a supervisory capacity where clear conflicts of interest exist. Those situations are comparatively straightforward to identify and address. The harder cases are the ones Redding focuses on: the supervisor who has become a genuine friend to their supervisee over years of shared professional experience, the mentor whose deep investment in a supervisee's success creates unconscious pressure to evaluate more leniently than objectivity requires, or the supervisee who has also become a close peer through shared professional community participation.

These situations are common precisely because good supervision tends toward genuine relationship. Supervisors who invest deeply in supervisees' development, who share their own professional struggles, who celebrate supervisees' achievements — these behaviors build the kind of trust that makes supervision effective, and they also create the relational proximity that can eventually complicate the objectivity and power balance that ethical supervision requires. Understanding how to navigate this tension is not optional for behavior analysts who supervise — it is a core professional competency.

Background & Context

The BACB Ethics Code's treatment of dual relationships has evolved across code revisions. The current Ethics Code (effective January 2022) addresses multiple relationships in Code 3.01, which requires behavior analysts to avoid relationships with supervisees (and other stakeholders) that could compromise professional judgment or create conflicts of interest, while recognizing that professional obligations can legitimately overlap and that community norms in specific settings may differ from those in others.

The dual relationship literature in allied health professions is instructive here. Psychology's ethics literature has documented extensively the ways in which multiple relationships compromise objectivity, create coercive dynamics, and generate boundary ambiguity that harms supervisees even when no obvious harm was intended. The behavior analytic literature has been slower to produce this documentation, but the ethical principles involved are not discipline-specific: any relationship in which one party holds formal evaluative power over another, while also occupying another relational role, creates conditions for the power differential to distort both the professional relationship and the personal one.

Mentorship and friendship are not the same relational category, and conflating them introduces its own complications. Mentorship is an intentionally developmental relationship: the mentor's goals include the mentee's professional growth, and the relationship is asymmetric by design. Friendship is a relationship between approximate equals that exists for its own sake rather than for developmental purposes. The supervisory relationship is neither of these by itself — it is a formal professional relationship with evaluative and developmental components — but in practice it can develop elements of both.

Cultural and contextual factors complicate the picture further. In smaller professional communities, among members of the same cultural or ethnic group, or in geographically isolated practice settings, the strict separation of professional and personal relationships may be practically impossible and culturally anomalous. Redding's presentation directly addresses these contextual variables, which is important because an ethics framework that does not engage with contextual reality is not a functional guide to practice.

Clinical Implications

The clinical implications of navigating mentorship-friendship dual relationships in supervision are primarily about what happens to supervisory objectivity when the relationship becomes personally close. Objectivity in supervision requires the capacity to evaluate supervisee performance honestly — to provide critical feedback that is accurate even when it is uncomfortable, to identify significant competency gaps even when doing so has consequences for the supervisee's certification progress, and to make decisions about supervisory endorsement that are based on professional assessment rather than personal loyalty.

When the supervisory relationship has developed strong personal dimensions, each of these requirements becomes more difficult. Critical feedback to a close friend feels like a personal betrayal. Identifying a significant competency gap in a supervisee toward whom you have deep personal investment activates the same psychological resistance as criticizing a friend. Withholding or qualifying supervisory endorsement when a supervisee is a personal friend creates relational consequences that purely professional relationships do not involve.

The research on evaluation in personal relationships consistently documents leniency effects: evaluators rate people they like more positively than objective performance warrants. In supervisory contexts, this leniency effect directly harms supervisees by allowing competency gaps to go unaddressed, harms clients who will be served by an inadequately prepared behavior analyst, and harms the field by endorsing practitioners whose competence was not rigorously evaluated.

The converse dynamic — where personal closeness has soured and the supervisory relationship becomes tainted by the negative interpersonal history — is equally problematic. Supervisors who have experienced relationship difficulties with a supervisee may underrate their performance, over-scrutinize their work, or fail to invest in their development in ways that reflect the personal history rather than the professional assessment.

Both dynamics illustrate the same structural problem: when personal and professional relationships are entangled, the professional relationship cannot operate with full independence from the personal one.

Ethical Considerations

Code 3.01 is the primary relevant standard, requiring behavior analysts to avoid multiple relationships that could impair professional judgment or create exploitation or harm. The code explicitly acknowledges that not all multiple relationships are avoidable and that behavior analysts must use judgment in navigating them — which means the ethical imperative is not to categorically prohibit all personal connection in supervisory relationships but to maintain active awareness of how personal dimensions are affecting professional conduct.

Code 4.04 addresses corrective feedback, which is specifically relevant here: supervisors must provide honest, accurate performance feedback to supervisees. A supervisor whose personal relationship with a supervisee leads them to soften, delay, or withhold corrective feedback is not meeting Code 4.04, regardless of the warmth and genuine investment that motivated the leniency. The supervisee's right to accurate developmental feedback is not overridden by the supervisor's discomfort with delivering it.

Code 4.06 addresses the BACB's requirement that supervisors provide only supervised experience that meets the BACB's requirements. Allowing personal loyalty to influence supervisory endorsements — certifying hours or competencies that were not rigorously assessed — violates Code 4.06 and has downstream consequences for the clients the supervisee will serve.

Code 1.04 addresses behavioral integrity: behavior analysts should be honest with themselves and others about the factors influencing their professional decisions. A supervisor who has noticed that personal closeness is affecting their evaluative objectivity but has not disclosed or addressed this has an integrity problem that Code 1.04 requires them to address, even if no external party is aware of it.

Assessment & Decision-Making

Assessing whether a mentorship-friendship dynamic has compromised supervisory objectivity requires honest self-examination using several behavioral indicators. Ask: Have I delivered critical feedback to this supervisee that was as specific, direct, and honest as I would have delivered to a supervisee with whom I had a purely professional relationship? Have my performance evaluations of this supervisee been based on observed behavior and measurable outcomes, or have they been influenced by my personal investment in their success? If this supervisee were not my friend, would I assess their competencies the same way?

The answers to these questions, honestly pursued, reveal whether the dual relationship has introduced the bias that makes it ethically concerning. If the answer to any of these questions suggests personal factors are distorting professional assessment, the appropriate response is not to deny the relationship but to actively compensate for its influence — through structured evaluation processes that minimize subjective judgment, through consultation with a colleague who can provide an objective second assessment, or through disclosing the relationship to a supervisor or ethics consultant for guidance.

Decision-making about whether a supervisory relationship has become too personally close to continue requires weighing the potential for harm against the disruptiveness of reassignment. In cases where bias is identifiable and significant, reassigning the supervisee to a different supervisor — or bringing in co-supervision to ensure independent evaluation — is the most ethically defensible option. This decision is difficult precisely because it involves acknowledging the limitation in a relationship that may be genuinely valuable, but Code 3.01 does not provide an exception for dual relationships that feel beneficial.

What This Means for Your Practice

Redding's presentation does not argue that supervisors should prevent themselves from developing genuine care and investment in their supervisees — that kind of connection is often what makes supervision most effective and most meaningful for both parties. It argues instead for active, ongoing awareness of how personal dimensions are operating within the professional relationship and for structural safeguards that protect objectivity even when personal closeness makes it more difficult.

For your practice, this means developing a habit of self-examination around your current supervisory relationships: Where are the relationships where personal closeness has developed most significantly, and what evidence do you have that your professional assessments have remained objective? What structural mechanisms do you have in place to protect evaluative integrity in those relationships — peer consultation, co-supervision, structured assessment tools that reduce subjective bias?

It also means being willing to have explicit conversations with supervisees about the relational dynamic and its professional implications — a conversation that itself requires the kind of transparency and directness that Code 1.04 demands and that good supervisory relationships can sustain. The supervisor who can name the dual relationship, discuss its implications, and co-create with the supervisee a structure that protects the professional relationship's integrity is modeling exactly the kind of ethical self-awareness the field needs more of.
