ABPP Clinical Psychology common mistakes
ABPP Clinical Psychology · Understand the traps and how to avoid them.
Selecting a diagnosis based on the single most salient symptom in a vignette (e.g., choosing major depressive disorder because mood is mentioned first) without checking duration, functional impairment, and exclusion criteria.
Vignettes are written to bury the discriminating feature (duration, onset relative to a substance or medical condition, presence of mania/hypomania) in a later sentence; candidates pattern-match on the first recognizable symptom cluster.
What to do instead
Before answering, write down the four to five DSM criteria that separate the top two contenders and locate each one in the stem. If a criterion is absent, the answer that requires it is wrong regardless of how well the rest fits.
Confusing assessment instrument purpose: choosing a screening tool when the stem asks for a diagnostic or differential measure, or choosing a self-report inventory when the question specifies a performance-based or clinician-administered method.
Candidates memorize instrument names and acronyms without tagging each by format (self-report vs. interview vs. performance), population, and purpose (screen, diagnose, track outcome, assess personality).
What to do instead
Maintain a one-line card per instrument with four fields: format, purpose, population, and key limitation. When reading a stem, extract those four requirements first, then match.
Applying a therapeutic technique from the wrong theoretical orientation to a case description (e.g., recommending cognitive restructuring for a problem the stem frames as maintained by avoidance and reinforcement contingencies).
Candidates learn interventions as a list of names rather than as derivations from a case formulation, so the named technique sounds plausible even when its mechanism does not match the described maintaining factors.
What to do instead
For each vignette, state the hypothesized maintaining mechanism in one sentence before looking at options, then choose the intervention whose mechanism matches. Eliminate any option that targets a mechanism the stem did not describe.
Ignoring base rates and setting-specific prevalence when answering a probability or 'most likely' question, treating all listed conditions as equally probable.
Clinical training emphasizes not missing dangerous diagnoses, which biases candidates toward rare but severe options over common ones; exam items exploit this by offering a rare dramatic diagnosis against a common one that fits equally well.
What to do instead
When two options both fit, ask which is more prevalent in the stated population and setting. Choose the common condition unless a stem feature (e.g., acute onset, focal neurologic sign) specifically raises the rare one.
Answering ethics items from personal or institutional practice norms rather than from the enforceable standard, e.g., deciding whether to break confidentiality based on what a particular supervisor or agency does.
Candidates generalize from their own training site's policies, which are often stricter or looser than the actual standard, and they have not separated aspirational principles from mandatory standards.
What to do instead
Classify each ethics item before answering: is it asking about an enforceable standard, an aspirational principle, or a legal requirement? Answer according to the enforceable standard, and treat agency policy as a floor only when the stem says so.
Missing the distinction between informed consent, assent, and authorization to release information, and selecting an answer that conflates them (e.g., treating a signed release as sufficient consent for a different service).
These terms are used loosely in everyday clinical speech, so candidates treat them as interchangeable and overlook that consent is service-specific and time-limited while a release covers disclosure of records.
What to do instead
Memorize the elements of each separately (consent: capacity, voluntariness, information, documentation; assent: minor's agreement plus guardian permission; release: scope, recipient, expiration, revocation). Match the stem to the correct instrument.
Choosing the option that protects confidentiality absolutely, or the option that discloses most freely, instead of the option that discloses the minimum necessary to the appropriate party for a defined purpose.
Candidates know confidentiality is important and gravitate to the most protective-sounding answer, but many ethics items test the narrow exceptions and the minimum-necessary principle, where the fully protective option is wrong.
What to do instead
For every confidentiality item, identify the specific exception or legal duty in the stem, then pick the answer that discloses the least information to the fewest people needed for that purpose. Reject both absolute-protection and broad-disclosure options.
Failing to recognize a multiple relationship when the second role is non-clinical (e.g., supervising a trainee who is also a friend, providing therapy to a colleague's employee, bartering for services), and concluding no conflict exists because the roles 'are not both therapy'.
Candidates define multiple relationships narrowly as sexual or familial and underestimate role conflicts involving power, evaluation, or financial ties, which are the most commonly tested forms.
What to do instead
For each scenario, list every role the psychologist holds and ask whether any role gives the psychologist power over, or a separate interest in, the other person. If yes, treat it as a potential multiple relationship and evaluate whether it is avoidable and whether it impairs objectivity.
Answering competence and supervision items by endorsing the option where the psychologist learns on the job or delegates without oversight, rather than the option that establishes competence before or alongside service delivery.
Candidates confuse 'seek consultation' with 'be competent' and accept supervision as a substitute for training, when the standard requires practicing within boundaries of competence and obtaining supervision or referral for areas outside them.
What to do instead
Apply a two-part test to each option: does the psychologist obtain the needed competence (training, supervision, consultation) before or concurrent with service, and does the plan include a boundary or referral? Reject options that have the psychologist practicing outside competence with only informal support.
Skipping or rushing the final review of flagged items, leaving changed answers unverified for reading errors such as 'EXCEPT', 'NOT', 'most' versus 'least', and 'initial' versus 'follow-up'.
Time pressure and fatigue lead candidates to answer stems from memory of similar items and to change answers impulsively at the end without re-reading the qualifier that determines the correct option.
What to do instead
Use a two-pass method: first pass answers only items you are confident on and flags the rest; second pass re-reads each flagged stem aloud mentally, underlines the qualifier, and confirms the chosen option answers the question actually asked. Do not change an answer unless you can name the specific misread or missed fact.
