Q

Speed based tests

A

Speed:
- time limited, not expected to finish, focus on performance

  • Mathematics and Reading Fluency in achievement tests (e.g., WIAT)
  • Block Design in Wechsler Intelligence Scales
  • > calculate scores with and without time bonus points for added interpretation

Q

Administration of tests

A
  • Paper-and-Pencil vs. Computerised Administration
  • Increasing test adaptation for computerised administration
  • > E.g., Wechsler scales designed for paper-and-pencil administration, Now available for administration on tablets via Pearson Q-interactives

Increased move to computerised adaptive test (CAT) format
- Items completed by any given test taker are individualised (adapted) based on running calculation of their ability/level

Q

Scoring and interpretation

A

Norm vs. Criterion referenced

Normed: comparison to average performance of normative or standardisation sample
“Bill performed better than 65% of same-age peers would be expected to”
- Most big commercial psychological tests are norm-referenced

Criterion referenced: comparison to objective criterion
“Mary met the criteria for being promoted”
- e.g., Driving Test, Citizenship Test, University grading

Q

Test quality

A
  • Consider issues of reliability, validity, and comprehensiveness
  • Scale development paper is an initial start
  • Manual will usually provide further evidence of these details
  • But manual information may be dated, selective, or biased
  • Ideally look at peer-reviewed journal articles that report information on test w/different samples (e.g. correlates w/similar measures, predicts future outcomes, etc.)
17
Q

Test competency

A

Competency in psychological assessment and testing requires knowledge of

  • Test construction/ scale development (assignment!)
  • Test bias, reliability and validity (psychometric soundness)
  • Relevant major psychological theories/constructs
  • Measurement and scoring issues
  • Ethical and legal issues around test administration
18
Q

Test-taker rights:

A
  • Competent assessment
  • Assessment using most appropriate, sound tools
  • Informed consent (purpose, time, location/use of results)
  • Treated in fair, impartial, courteous manner
  • Be informed of test results
  • Privacy
  • Have findings held confidential
  • Least stigmatizing label (e.g., feeble minded, moron)
19
Q

Risks of incompetency

A
  • Inappropriate diagnosis
  • Personal distress
  • Inadequate or inappropriate treatment/intervention
  • Poorly informed educational, career, or life decisions
  • Legal risks
  • Invalidation of diagnostic tools (e.g., test-retest period, security breaches)
20
Q

Principles relating to publication, distribution, and use of psychological tests (APS)

A

Members (incl. students) must not:

  • publish/divulge test contents to mass media or public display
  • ignore restriction on distribution of tests set by test suppliers
  • act as agent to obtain tests for untrained others
  • let tests fall into the hands of the general public/unqualified users
  • allow students to use tests unsupervised
  • allow students to retain tests
  • provide test answers to the general public
  • attempt to affect performance on any individual being assessed
21
Q

Testing responsibilities and students

A

When using “test materials for teaching or demonstration purposes, students or trainees are made aware of the full, delegated responsibilities they take on, particularly in relation to the non-disclosure of secure test materials and the confidentiality of results”

22
Q

Can test-takers provide true, informed consent?

A

Consider various tests/assessments we encounter throughout the lifespan.
- Developmental ability to understand
- Language
- Mental capacity
Are we (or are parents) able to provide truly informed consent for:
- Diagnostic educational assessments?
- Assessments used in the workplace ?
- Neurological assessments (e.g. dementia)?

This is why informed consent is so important. Understanding what the test measures, what it will be used for, whether and how it is appropriate for use, whom will have access to information in the future.

23
Q

Publisher restrictions

A

Depending on the nature (content) and usage (educational assessment, clinical diagnosis), test publishers will restrict access to certain psychological tests
