CASAC Screening, Assessment, and Diagnosis 2 — Questions and Answers

Question 1: When conducting a substance use history during assessment, which of the following information is most important to obtain for each substance used?

Only the name of the substance
Age of first use, route of administration, frequency and quantity of current use, last use, and previous treatment episodes (Correct answer)
How much the client spent on substances
Whether the client's friends also use substances

Correct answer: Age of first use, route of administration, frequency and quantity of current use, last use, and previous treatment episodes

A comprehensive substance use history must capture the full picture of each substance including onset, route, pattern, recency, and treatment history.

A thorough substance use history is the cornerstone of assessment and must be collected for every substance the client has used. Essential elements include: (1) Age of first use — early onset (before age 15) is associated with greater severity and worse outcomes; (2) Route of administration — oral, nasal, smoked, injected — each carries different health risks and indicates different levels of use severity; (3) Frequency of current use — daily, weekly, binge pattern; (4) Quantity — amount used per occasion; (5) Last use — critical for determining withdrawal risk and timing; (6) Progression pattern — how use has changed over time; (7) Periods of abstinence — when, how long, what supported them; (8) Previous treatment episodes — types, duration, what was helpful, reasons for relapse; (9) Consequences experienced — medical, legal, social, occupational; (10) Withdrawal history — any previous withdrawal complications, seizures, delirium. This comprehensive history informs: detoxification planning, level-of-care determination, treatment planning, relapse risk assessment, and outcome evaluation. The information should be gathered in a non-judgmental, systematic manner.

Question 2: The PHQ-9 (Patient Health Questionnaire-9) is commonly used in substance abuse settings to screen for which co-occurring condition?

Anxiety disorders
Major depressive disorder (Correct answer)
Attention deficit hyperactivity disorder
Personality disorders

Correct answer: Major depressive disorder

The PHQ-9 is a validated 9-item screening tool specifically designed to assess the severity of depressive symptoms based on DSM criteria.

The PHQ-9 is a brief, self-administered screening instrument that assesses the nine symptom criteria for major depressive disorder as defined by the DSM-5. Clients rate how often they have been bothered by each symptom over the past two weeks on a scale of 0 (not at all) to 3 (nearly every day). Total scores range from 0-27, with severity classifications: 0-4 minimal, 5-9 mild, 10-14 moderate, 15-19 moderately severe, 20-27 severe. The ninth item specifically asks about suicidal ideation, making it clinically actionable. In substance abuse settings, the PHQ-9 is valuable because: (1) Depression is the most common co-occurring psychiatric condition with SUDs; (2) It can be administered repeatedly to track changes over time; (3) It helps differentiate substance-induced depressive symptoms (which should improve with abstinence) from independent depressive disorder (which may require separate treatment); (4) It is brief enough for routine screening without disrupting clinical workflow; (5) It has been validated in diverse populations including substance abuse treatment clients. However, scores should be interpreted in clinical context — acute intoxication or withdrawal can artificially elevate scores.

Question 3: What is the clinical significance of distinguishing between a substance-induced psychiatric disorder and an independent psychiatric disorder in a client with co-occurring substance use?

There is no clinical difference between the two
The distinction guides treatment — substance-induced disorders are expected to resolve with abstinence, while independent disorders require ongoing psychiatric treatment even after substance use stops (Correct answer)
Substance-induced disorders are always more severe
Independent disorders cannot co-occur with substance use

Correct answer: The distinction guides treatment — substance-induced disorders are expected to resolve with abstinence, while independent disorders require ongoing psychiatric treatment even after substance use stops

Distinguishing between substance-induced and independent psychiatric disorders is essential because it determines whether psychiatric symptoms will resolve with abstinence or require separate, ongoing treatment.

The differential diagnosis between substance-induced and independent psychiatric disorders has direct treatment implications. Substance-induced disorders: caused by the direct pharmacological effects of substance use (intoxication or withdrawal). Key features include temporal relationship (symptoms begin during or soon after substance use/withdrawal), symptom resolution with sustained abstinence (typically within 2-4 weeks), and symptom characteristics matching the known effects of the substance (e.g., stimulant-induced psychosis, alcohol-induced depression). Treatment focus: achieve and maintain abstinence; psychiatric symptoms are expected to resolve. Independent disorders: exist separately from the substance use, though they may be exacerbated by it. Diagnostic indicators include: onset before substance use began, persistence during extended abstinence periods, family history of the psychiatric condition, and symptom severity exceeding what would be expected from the substance's pharmacological effects. Treatment requires: ongoing psychiatric intervention (medication, psychotherapy) in addition to substance abuse treatment. A monitored abstinence period (2-4 weeks minimum) is often necessary to clarify the diagnosis. Misdiagnosis in either direction can lead to: unnecessary psychiatric medication or, more dangerously, failure to treat an independent psychiatric condition.

Question 4: When assessing a client's readiness for change regarding substance use, which validated instrument specifically measures motivation and readiness along the stages of change continuum?

Beck Depression Inventory
URICA (University of Rhode Island Change Assessment) (Correct answer)
MMPI-2
CAGE questionnaire

Correct answer: URICA (University of Rhode Island Change Assessment)

The URICA is specifically designed to measure an individual's readiness for change across the stages of the Transtheoretical Model, helping match interventions to the client's current stage.

The University of Rhode Island Change Assessment (URICA) is a 32-item self-report measure specifically designed to assess readiness for behavior change based on Prochaska and DiClemente's Transtheoretical Model. It measures four subscales corresponding to stages of change: Precontemplation (not recognizing a problem or considering change), Contemplation (ambivalent about change), Action (actively making changes), and Maintenance (sustaining changes already made). A composite 'readiness' score can be calculated by summing Contemplation, Action, and Maintenance scores and subtracting the Precontemplation score. Clinical applications include: (1) Treatment matching — aligning interventions with the client's current stage (MI for contemplation, action planning for preparation/action); (2) Progress monitoring — tracking movement through stages over time; (3) Treatment planning — identifying specific barriers to change at each stage; (4) Clinical supervision — helping counselors avoid stage mismatches (using action techniques with precontemplators). The URICA is not a diagnostic tool and should be interpreted alongside clinical interview data. Other readiness measures include the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) and the Readiness Ruler.

Question 5: A substance abuse counselor administers the Columbia-Suicide Severity Rating Scale (C-SSRS) to a new client. What specific aspect of suicide risk does this instrument assess?

It measures the client's general happiness level
It systematically classifies suicidal ideation by severity (passive to active with plan and intent) and assesses suicidal behavior, providing a structured risk classification (Correct answer)
It only asks whether the client has ever thought about death
It diagnoses depression

Correct answer: It systematically classifies suicidal ideation by severity (passive to active with plan and intent) and assesses suicidal behavior, providing a structured risk classification

The C-SSRS provides a structured classification of suicidal ideation severity (from passive wish for death to active ideation with specific plan and intent) and documents suicidal behaviors.

The Columbia-Suicide Severity Rating Scale (C-SSRS) is a structured clinical assessment tool that provides a comprehensive evaluation of suicidal ideation and behavior. It assesses ideation across a severity spectrum: (1) Wish to be dead — passive ideation without specific suicidal thoughts; (2) Non-specific active suicidal thoughts — thinking about killing oneself without specific method; (3) Active suicidal ideation with any methods (not a specific plan) — thinking about methods without a specific plan; (4) Active suicidal ideation with some intent to act, without specific plan; (5) Active suicidal ideation with specific plan and intent — the highest severity level. It also documents suicidal behavior: actual attempts (with or without injury), interrupted attempts, aborted attempts, and preparatory behavior. For substance abuse counselors, the C-SSRS is particularly valuable because: it provides a common language for communicating risk level to the treatment team, it can be administered repeatedly to track risk changes, it helps determine appropriate intervention level, and it documents risk assessment thoroughly for clinical and legal purposes.

Question 6: What is the primary purpose of conducting a comprehensive psychosocial assessment in addition to substance-specific screening in a substance abuse treatment setting?

It is solely required for insurance billing purposes
It identifies the broader context of the client's functioning including relationships, employment, housing, legal issues, trauma history, and strengths that must be addressed for successful recovery (Correct answer)
It replaces the need for a substance use history
It is only necessary for clients with co-occurring disorders

Correct answer: It identifies the broader context of the client's functioning including relationships, employment, housing, legal issues, trauma history, and strengths that must be addressed for successful recovery

Comprehensive psychosocial assessment identifies the full range of factors affecting recovery, enabling treatment plans that address the whole person rather than substance use in isolation.

A comprehensive psychosocial assessment examines the complete context of a client's life to support holistic treatment planning. Essential domains include: (1) Social/relationship functioning — family dynamics, social support, interpersonal skills, isolation patterns; (2) Employment/education — work history, current employment, vocational skills, educational attainment, career goals; (3) Housing — stability, safety, living environment recovery-supportiveness; (4) Legal — current charges, probation/parole, history of legal involvement, pending cases; (5) Financial — income, debt, benefits eligibility, financial stressors; (6) Trauma and abuse history — physical, sexual, emotional abuse, neglect, witnessing violence, other traumatic experiences; (7) Medical history — chronic conditions, medications, healthcare access, HIV/hepatitis risk; (8) Mental health — psychiatric history, current symptoms, previous treatment, family mental health history; (9) Strengths and resources — resilience factors, coping skills, motivation, cultural resources, spiritual practices; (10) Cultural factors — cultural identity, acculturation, culturally specific risk and protective factors. All these domains interact with and influence substance use. A treatment plan that addresses only the substance use while ignoring unstable housing, active trauma responses, or legal pressures is unlikely to produce sustained recovery.
