What is a Test?

  • A test can be defined as a measuring device or procedure.

  • Psychological tests specifically measure psychological variables such as:

    • Intelligence

    • Personality

    • Aptitude

    • Interests

    • Attitudes

    • Values

  • Psychological tests differ in:

    • Content

    • Format

    • Administration procedures

    • Scoring and interpretation procedures

    • Technical quality

Content of Psychological Tests

  • The content varies according to the specific focus of the tests.

  • Different definitions of constructs (e.g., personality) can lead to variations in item content.

  • Test developers have differing theoretical orientations influencing their definitions.

Specific Content Examples

  • Lesbian, Gay, Bisexual Positive Identity Measure (LGB-PIM)

    • Insightfulness about oneself linked to LGBT identity.

    • Self-awareness and advocacy for LGBT rights linked to identity.

  • Internalized Homophobia (IHP)

    • Feelings about attraction to the same gender and wishes for change.

Format of Tests

  • Refers to the layout and arrangement of test items, including time limits.

  • Formats can be:

    • Computerized

    • Pencil-and-paper

Administration Procedures

  • Some tests require knowledgeable administrators, especially for one-on-one tests.

  • Pre-recorded versus interactive administration methods exist.

Scoring and Interpretation Procedures

  • Score represents an evaluation reflecting performance on a test.

  • Scoring is the process of assigning evaluative codes or statements to performance.

Technical Quality

  • Concerns measuring consistency and accuracy in what a psychological test purports to measure.

What constitutes a Test? (Thorndike & Thorndike-Chris)

  • Components of a test include stimuli/items, participant answers, and standardized scoring procedures.

Historical Context of Psychological Testing

  • First developed by Alfred Binet in 1905 (Binet-Simon Scale) for educational placement.

Areas of Application for Psychological Testing

  • Education: Assessing learning disabilities.

  • Work: Recruiting and resource identification.

  • Orientation: Academic and professional guidance.

  • Clinical: Identifying psychological issues.

Types of Tests

  • Objective: Defined scoring procedures.

  • Subjective: Subjective scoring assessment.

  • Projective: Participants provide personal and subjective responses based on ambiguous stimuli.

Testing vs. Assessment

  • Testing: Measuring psychology-related variables through standard tests.

  • Assessment: Data gathering and integration leading to psychological evaluation using tests, interviews, case studies, etc.

Different Aspects of Assessment

  • Gain metrics about abilities or attitudes.

  • Solve problems or answer referral questions.

Evaluator Role in Testing vs Assessment

  • Testers: Exchange roles with minimal impact.

  • Assessors: Crucial role in selecting tests and interpreting data.

Skills of the Evaluator

  • Testers require basic skills in administering and scoring tests.

  • Assessors need educated tool selection and integration capability.

Outcome Differences between Testing and Assessment

  • Testing yields numeric scores.

  • Assessment utilizes logic from diverse data sources to address questions.
