COCAS key terms

The process of systematically distinguishing between two or more conditions that share overlapping symptoms, so that the best-fitting explanation is identified before treatment planning begins.

An individualized explanatory account that integrates predisposing, precipitating, perpetuating, and protective factors to guide treatment selection for a specific client.

The frequency with which a condition occurs in a given population; it strongly influences how much weight a positive or negative assessment finding should carry.

Sensitivity is the proportion of people with a condition who test positive; specificity is the proportion without it who test negative. Together they describe a measure's discriminative accuracy.

The probability that a person actually has (or does not have) a condition given a particular test result; it depends on both test accuracy and the condition's prevalence.

A structured observational assessment covering appearance, behavior, speech, mood and affect, thought process and content, cognition, insight, and judgment, used to document current functioning.

A structured appraisal of the likelihood and imminence of harm to self or others, including identified risk factors, protective factors, and the rationale for a chosen level of care.

A working hypothesis about the origins and maintenance of a client's difficulties that links assessment findings to a specific intervention plan and is revised as new data emerge.

A therapeutic procedure in which clients learn to identify, evaluate the evidence for, and replace distorted automatic thoughts with more balanced and accurate interpretations.

Brief, spontaneous interpretations that arise in response to events and can bias emotional reactions; they are often outside awareness until deliberately elicited and examined.

A systematic pattern of biased thinking, such as catastrophizing or overgeneralization, that maintains distress by misrepresenting available evidence.

A structured intervention that schedules meaningful activity based on values and goals, aiming to increase contact with reinforcement and reverse withdrawal cycles in depression.

Planned, repeated contact with feared stimuli without avoidance or escape, allowing fear responses to diminish through new learning rather than mere distraction.

A learning process in which the frequency of a behavior changes as a result of the consequences that follow it, such as reinforcement or punishment.

The collaborative emotional bond and shared agreement on tasks and goals between client and clinician, which predicts engagement and treatment outcome.

The ongoing process of disclosing the nature, risks, benefits, and alternatives of treatment, confirming comprehension, and documenting the client's voluntary agreement.

The ethical and legal duty to protect client information, together with the recognized exceptions, such as imminent danger or mandated reporting, that permit or require disclosure.

A legal obligation, arising in many jurisdictions after a credible threat to an identifiable person, to take reasonable steps such as warning, notifying authorities, or arranging protective services.

A situation in which a clinician holds another role with a client, supervisee, or their close associates, creating risk of impaired objectivity, exploitation, or harm.

A departure from customary professional practice that may be benign or may precede harm; it is evaluated by context, client welfare, and whether it is disclosed and documented.

The range of services a clinician is trained and qualified to provide, which must be expanded only through appropriate education, consultation, or supervised experience.

Providing clients and families with accurate information about a condition, its course, and its treatment, to build understanding, reduce blame, and support adherence.

The degree to which a client takes a prescribed medication as directed; it is influenced by side effects, cost, beliefs, and the quality of the therapeutic relationship.

A team-based model in which mental health and medical providers coordinate treatment, share information with proper consent, and jointly monitor outcomes.

A written, time-limited, and revocable client authorization specifying what information may be shared, with whom, and for what purpose.

The process of giving prospective participants complete information about purpose, procedures, risks, and voluntariness so they can decide freely whether to take part.

A committee that reviews research involving human participants to ensure risks are minimized, selection is fair, and consent and privacy protections are adequate.

Clinical decision-making that integrates the best available research, the clinician's expertise, and the client's values, preferences, and circumstances.

A study in which participants are randomly assigned to conditions, allowing stronger causal inference about an intervention's effects than observational designs permit.

A standardized index of the magnitude of a difference or association, used to judge practical importance independently of whether a result reached statistical significance.

A lifelong stance of self-reflection, openness to correction, and attention to power differences that supports respectful work across cultural identities.

A structured method for describing a client's cultural identity, explanatory models of illness, stressors, and supports, and how these shape the clinical encounter.

Automatic associations that can influence perception and judgment outside conscious awareness; recognizing them is a step toward reducing their impact on clinical decisions.

A structured, evaluative relationship in which a more experienced clinician monitors and develops a supervisee's competence while attending to client welfare and role boundaries.

A voluntary, non-evaluative request for another professional's expertise on a case or program, with the consultee retaining responsibility for decisions.

Supervision organized around observable knowledge, skill, and attitude benchmarks, with direct observation and structured feedback used to document trainee development.

Establishing charges that reflect the value and cost of services while offering adjusted rates based on documented financial need, disclosed in advance and applied consistently.

Ending services in a planned, ethically sound way, or transferring care when the clinician cannot meet the client's needs, with adequate notice and continuity safeguards.
