Study Notes
Reliability and Validity of Interviews
- Interviews are frequently used in assessment but have limitations in reliability and validity
- Different interviewers may approach topics differently impacting client responses
- Even with consistent interview structures, nonverbal cues can influence results
- Limited research on inter-rater and test-retest reliability for interviews
- Interviews show good reliability for DSM-IV diagnoses
- Clients may distort information purposely, impacting validity
- Unstructured interviews are among the least reliable and valid assessment tools
Interview Strategies and Techniques
- Comprehensive and accurate information related to the assessment is crucial.
- Employ open-ended questions, encouragement, paraphrasing, and summarizing during interviews.
- Clinicians must interpret and integrate information accurately, considering recurring themes and multiple sources.
- Cultural biases can influence interpretations, necessitating awareness of client's race, ethnicity, social class, gender, and disability.
Observations
- Appearance: Evaluate grooming, clothing appropriateness, and alignment with the situation.
- Attitude: Assess calmness, cooperation, or hostility.
- Behavior: Note unusual movements or psychomotor changes.
- Speech: Evaluate rate, tone, and volume of speech.
- When used for diagnostic decisions, observations should have high reliability (0.8 to 0.99), with scores above 0.80 considered highly reliable.
Validity
- Refers to the extent to which inferences drawn from an instrument are meaningful and appropriate.
- Content validity: Measures whether items align with the intended scope of the assessment
- Face validity: Appraisal of a test's content based on initial perception.
- Construct validity: Determines if the measure accurately reflects the underlying theoretical construct.
-
Criterion-related Validity: Compares a test to another measure or outcome considered valid.
- Concurrent: Test scores and criterion performance scores are collected concurrently.
- Predictive: Criterion performance is measured some time after the test score.
- Incremental Validity: Indicates if a predictor adds value beyond existing measures in predicting an outcome.
Interview Structure
- Structured Interviews: Utilize predetermined questions in a fixed sequence, with limited flexibility.
- Semi-structured Interviews: Prescribed topics and general questions, with flexibility in sequencing and follow up.
- Unstructured Interviews: Leaves decisions regarding interview conduct to the practitioner's judgment, offering maximum flexibility.
Intake Interview
- A conversation between a counselor and client with a defined purpose.
- May include testing as part of the process.
Assessment
- Umbrella term for systematic procedures involving multiple sources and inferences.
- Includes evaluation, appraisal, and testing
Tests
- Standardized processes for sampling and describing a behavior of interest.
Measurement
- Assigning numbers to attributes of people based on specific rules.
Purposes and Uses of Assessment Information
- Screening applicants for employment, education, and human service programs.
- Classifying and placing individuals in educational and business settings.
- Evaluating work or academic performance for purposes like promotion or graduation.
- Providing personal counseling and guidance.
- Diagnosing conditions and establishing a baseline for treatment.
- Evaluating the effectiveness of interventions.
Common Assessment Hazards (Anastasi 1992)
- Hazard of the single score: Use a score range with a margin of error.
- Hazard of the single time period: Be cautious with dated results or limited observations.
- Hazard of the single indicator: Employ multiple methods for assessing a construct.
- Hazard of illusory precision: Avoid over-emphasizing numerical scores as inherently more objective than observations due to quantification.
Organizing Assessment Information
-
Assessment Report:
- Identifying Information
- Reason for Referral
- Background Information
- Behavioral Observations
- Results and Interpretation
- Recommendations
- Summary
- Signature
- Addendum (to clarify results shared with the client and their impressions)
Informed Choice and Consumer Empowerment in Assessment
- Informed choice: Individuals set goals, gather information, consider options, and take responsibility for choosing the most suitable option.
-
Consumer Empowerment:
- Establish a collaborative relationship with clients.
- Understand and analyze client needs, expectations, values, and goals.
- Communicate information about the evaluation process.
- Encourage active client participation and analysis of information.
