8.5 Assessment, Intervention, Supervision, and Evidence Ethics
Key Takeaways
- Assessment standards (9.01-9.11) require valid instruments, qualified administration, explained results, and protected test security.
- Evidence-based practice (EBP) integrates the best research evidence, clinical expertise, and patient values/characteristics — not a single rigid protocol.
- Supervisors retain responsibility for client welfare and may delegate only work a supervisee can competently perform (Standards 2.05, 7.06).
- Standard 9.06 requires noting factors (language, culture, disability) that limit the accuracy or interpretation of assessment data.
Ethics Inside Core Psychological Work
An ethics item often arrives disguised as a testing, diagnosis, treatment, or supervision vignette. The ethical issue is hidden inside ordinary professional work.
Assessment ethics (Standards 9.01-9.11). Psychologists base opinions on information and techniques sufficient to support their findings (9.01). They use instruments whose validity and reliability have been established for the population tested (9.02) and obtain informed consent for assessment (9.03). Standard 9.06 requires interpreting results in light of factors — language, culture, disability, situational, and test-taking variables — that may reduce accuracy, and noting significant limitations.
Only qualified persons administer tests (9.07), obsolete/outdated results are not used (9.08), and test security of materials and items is maintained (9.11). Raw test data may be released to clients/authorized parties per 9.04, but secured materials are protected.
| Practice area | Ethical concern | Strong response pattern |
|---|---|---|
| Assessment | Invalid use or overinterpretation | Match instrument, norms, and validity evidence to the referral question (9.02) |
| Diagnosis | Bias or thin data | Use adequate data, differential diagnosis, and cultural formulation |
| Intervention | Unmonitored or unsupported treatment | Integrate research evidence, expertise, and client values; monitor progress |
| Crisis care | Safety and level of care | Assess risk, act within competence, consult, document, refer as needed |
| Supervision | Client welfare and supervisee competence | Clarify roles, monitor work, give feedback, document (2.05, 7.06) |
Diagnosis, Evidence-Based Practice, and Termination
Diagnosis carries weight because labels affect treatment, insurance, stigma, accommodations, and legal decisions. Avoid diagnosing from a thin record; weigh differential diagnosis, medical factors, substance use, trauma, development, and culture. Ethical diagnosis is accurate and humble about limits.
Evidence-based practice in psychology (EBPP), as defined by APA, is the integration of the best available research, clinical expertise, and patient characteristics, culture, and preferences. The exam trap is the answer that forces a single manualized protocol on every client regardless of fit; the correct stance integrates all three pillars and monitors response, adjusting when treatment is not helping or risk changes.
Termination (Standard 10.10). Services end when the client no longer needs them, is not benefiting, or is being harmed by continuation, or when threatened by the client or a third party. Pre-termination counseling and appropriate referrals are required except where precluded by the client's or a third party's conduct. Abrupt termination without transition risks abandonment.
Supervision Ethics
Supervision is more than being available for questions. Under Standards 2.05 (Delegation) and 7.06 (Assessing Student/Supervisee Performance), supervisors delegate only work a supervisee can competently perform, retain responsibility for client welfare, clarify expectations, evaluate competence on timely and specific criteria, give feedback, manage the inherent power differential, and document. If a supervisee practices outside competence or makes repeated errors, the supervisor must intervene — protecting the supervisee's feelings cannot outweigh client welfare.
Consultation likewise has confidentiality limits: share only the minimum identifying information necessary for competent input (Standard 4.06), not as gossip or a way to dodge responsibility.
For the exam, connect the task to the duty. If the stem is about a test, ask whether the instrument fits and is interpreted with its limits. If it is about therapy, ask whether consent, evidence, monitoring, and risk are handled. If it is about supervision, ask whether the supervisor is actively protecting clients.
Test Security, Raw Data, and Computer Reports
Two assessment items recur on the EPPP and are easy to confuse. Standard 9.04 (Release of Test Data) treats test data — raw and scaled scores, client responses, and the psychologist's notes about the client during the exam — as releasable to the client or to others with a valid release. Standard 9.11 (Maintaining Test Security) protects test materials — manuals, instruments, protocols, and test items — from release that would compromise their integrity. The trap blends them: a valid release entitles a client to their data, but not to copyrighted test items.
When law conflicts (e.g., a court compels materials), the psychologist takes reasonable steps to maintain security, such as a protective order.
Standard 9.09 (Test Scoring and Interpretation Services) holds the psychologist responsible for the appropriate application and interpretation of automated or computer-generated reports — the psychologist cannot hide behind a software narrative.
| Concept | What it covers | Release rule |
|---|---|---|
| Test data (9.04) | Raw/scaled scores, responses, exam notes | Release with valid authorization |
| Test materials (9.11) | Manuals, items, protocols | Protect security; do not release items |
| Computer interpretation (9.09) | Automated narratives | Psychologist retains interpretive responsibility |
| Obsolete results (9.08) | Outdated scores/tests | Do not base decisions on them |
Research and Publication Ethics
Because the domain spans professional issues, the EPPP also tests research ethics from Standards 8.01-8.15. Key points: informed consent for research (8.02) and for recording (8.03); deception (8.07) is permissible only when justified by significant value, no equally effective non-deceptive alternative exists, and it is not expected to cause pain or severe distress, with debriefing (8.08) afterward; Institutional Review Board (IRB) approval is required before data collection.
Publication standards bar plagiarism (8.11) and improper publication credit (8.12) — authorship reflects relative scientific contribution, and a student is generally listed as principal author on work substantially based on their dissertation. Data fabrication or falsification (8.10) is a severe integrity violation. The correct EPPP answer never trades participant welfare or scientific honesty for convenience or career advantage.
A psychologist uses a test normed only on English-speaking adults to evaluate a client who primarily speaks Spanish, without noting any limitation. Which standard does this most directly implicate?
Which statement best captures evidence-based practice in psychology (EBPP) as defined by APA?
A practicum supervisee is providing therapy beyond their demonstrated competence and making repeated clinical errors. What must the supervisor do?
