Psychology: Assessment and Diagnosis

Definition and Purpose

• Psychological assessment refers to the process of evaluating an individual's cognitive, emotional, and behavioral functioning using standardized tests and procedures.
• The purpose of psychological assessment is to identify strengths and weaknesses, diagnose mental health conditions, and guide treatment planning.

Types of Assessment

• Norm-referenced assessment: compares individual's performance to that of a larger group (e.g., intelligence quotient (IQ) tests).
• Criterion-referenced assessment: evaluates individual's performance based on a specific standard or criterion (e.g., passing a driving test).
• Inferential assessment: makes inferences about an individual's underlying psychological processes or traits (e.g., personality tests).

Assessment Methods

• Self-report measures: individuals provide information about themselves through questionnaires, rating scales, or interviews.
• Behavioral observations: observer records individual's behavior in a controlled or naturalistic setting.
• Physiological measures: assesses physiological responses (e.g., heart rate, skin conductance) to understand psychological processes.
• Performance tasks: evaluates individual's performance on specific tasks or activities.

Test Development and Evaluation

• Test development: involves creating a test, piloting it, and refining it to ensure reliability and validity.
• Reliability: consistency of test scores across different administrations or scorers.
• Validity: extent to which a test measures what it claims to measure.

Ethical Considerations

• Informed consent: individuals must understand the purpose and potential risks of the assessment.
• Confidentiality: assessment results should be kept confidential and only shared with authorized individuals.
• Cultural sensitivity: assessments should be fair and unbiased, taking into account cultural differences.

Clinical Applications

• Diagnosis and treatment planning: assessment results inform diagnosis and guide treatment decisions.
• Screening and prevention: early identification of mental health issues enables early intervention and prevention.
• Research and evaluation: assessments help researchers evaluate the effectiveness of interventions and programs.
