Performance Assessment - WHY?

To assess important problem solving, critical thinking, communications, hands-on and other complex skills that:

– Impact clients' safety and welfare if not performed adequately and

– Are difficult to assess in a multiple choice question format

Page 6: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

HOW?• ‘Pot luck’ direct observation (e.g., medical

rounds, clerkships and internships)• Semi-structured assessments (e.g. orals

and Patient Management Problems) • Objective, Structured Clinical Examinations

(OSCEs) (combining standardized client interactions with other formats)

• Other standardized simulations (e.g., airline pilots' simulators)

• Electronic simulations (e.g., real estate, respiratory care, architecture)

Validity – an ascent from Practice Analysis to Test

ResultsJob/practice analysis

– Who/what contexts?– How?

Test specifications & sampling– Which competencies?– Which tasks/scenarios?– Other parameters?

Item writing and review– Who and how?

Scoring– Analytic (checklists) &/or holistic (scales)?

Detect and minimize unwanted variability, e.g.:– Items/tasks – does the mix matter?– Practice effect – how can we avoid it?– Presentation/administration – what is the impact of

different SPs, computers, materials/equipment?– Scores – how do we know how accurate and dependable

they are? What can we do to improve accuracy?

Set Defensible Pass-fail Standards– How should we do this when different standard setting

methods -> different standards?– How do we know if the standard is appropriate?

Report Results– Are they clear? Interpreted correctly?– Are they defensible?

Evolution of Simulation Exam Format

• AMP’s parent company, NBRC, provided oral exams from 1961 to 1978

• Alternative sought due to:– Limited number of candidates that

could be tested each administration– Cost to candidates who had to travel

to location– Concern about potential oral

examiner bias

Page 20: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Evolution of Simulation Exam Format

• Printed simulation exam format introduced in 1978 using latent image technology

• Latent image format used by NBRC from 1978 to 1999

• NBRC decision to convert all exams to computer-based testing

• Proprietary software developed by AMP to administer simulation exams in comparable format via computer – introduced in 2000

• Both latent image test booklets & computerized format being used

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

How Simulation Exams Differ from MCQs

• Provides accurate assessment of higher order thinking related to a content area of interest (testing more than just recall)

• Challenge test takers beyond complexity of MCQs

• Simulation problems allow test takers to assess their skills against test content drawn from realistic situations or clinical events

IG Section Details

• IG section– A section in which test takers choose

information that will best help them understand a presenting problem or situation

– Facilitative options may receive scores of +3, +2, or +1

– Uninformative, wasteful, unnecessarily invasive, or potentially illegal options may receive scores of –1, –2, or –3

– Test takers who select undesirable options accumulate negative section points

Page 28: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

IG Section Details

• IG Section Minimum Pass Level (MPL)– Among all options with positive scores

in a section, some should be designated as REQUIRED for minimally competent practice

– The sum of points for all REQUIRED options in a section equals MPL

Page 29: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

DM Section Details

• DM section– A section of typically 4-6 options in which

the test taker must make a decision about how to handle the presenting situation

– Facilitative options may receive scores of +3, +2, or +1

– Harmful or potentially illegal options may receive scores of –1, –2, or –3

– Test takers who select undesirable options accumulate negative section points and are directed to select another option

First Principles

• If it’s worth testing, it’s worth testing well– it is possible to test anything badly– this is more expensive

• Some things are not worth testing– trivia– infrequently used skills

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Focus of Station

• Each station must have a clear focus– establish the focus in one sentence– take time to get this right– you can’t write a good station without

a clear focus

• Example: Perform passive range of motion of the arm for a client who has had a stroke.

Page 59: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

SP Portrayal - General

• Consider SP movement, behaviour– a picture in your head– use real situations to guide you

• Not detailed yet• Example: Client is 55 years old, is

disoriented, and has no movement in the left arm or leg.

“OSCE Research: The Key to a Successful

Implementation”

Page 72: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Prior to the OSCE: CPBC and PEBC

• Need for assessing communication, counseling, and interpersonal skills to provide pharmaceutical care to patients

• PEBC MC examination was not assessing the full scope of pharmacy practice as profiled by NAPRA (National Association Pharmacy Regulatory Authorities of Canada)

Page 73: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Generalizability: Data Analyses

• Psychometrically, OSCEs, are complex phenomena, producing scores with potential errors from multiple sources, including: – Examiners (pharmacists and non-

pharmacists)– Cases (context, complexity, # of

stations)– Scoring methods (global vs. checklists)– Standard setting– Differential grading practices

Page 74: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Research Question # 1

• How many examiners are required to obtain consistent and dependable candidates’ scores?

Page 75: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Results #1-1998

• 1 examiner per case yielded similar consistency as 2 (G=.82, .81, D=.81, .79) indicating that examiners agreed highly on their scores

• Examiners contributed little to the scoring errors of candidates’ performance

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Research Question # 2

• How many cases are required to maintain consistency, validity and generalizability of scores? – Adequate and representative sampling of

professional practice are necessary to capture a candidate’s abilities.

– Multiple observations of abilities yield more consistent and content valid inferences.

– Logistical constraints restrict the number of cases that are timely and economically feasible to administer within one OSCE examination.

Page 78: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Results # 2-1998

• 15 cases reduced the candidate’s score error due to sampling variability of the cases dramatically from 5 or 10 cases and improved the consistency of scores from G=.60 to .81

• 15 cases reduced the cases and raters interaction variance as an indication that raters agreed on their scores across cases

Page 79: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Results # 2-1998• Candidates’ scores varied mostly due

to their differential performance across cases.

• Sampling of the cases might affect the candidates’ performance on an OSCE.

• We suggest, however, that differential performance across cases might be due to candidate’s differential levels of skills across the pharmacy competencies assessed

Research Question # 3

• How do different scoring methods such as checklists or global grading affect candidates’ scores?

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Results # 3-1998

• Low correlations between checklist and global scores suggest both methods might not be interchangeable

• If used in isolation they would yield different end results, particularly for borderline candidates

• Global grading yields higher mean scores than checklist grading (p values.81 and .59)

Results # 4-1998

• SME’s agreed highly on the minimum standard necessary for safe pharmacy practice for the borderline qualified pharmacists

• On different occasions, SME’s had similar standards for entry-to-practice for the core cases

• Standards varied little between 26 & 20 cases and were consistent enough with 15 cases (G=.74, .74, .71)

Results # 5-Videos 2003• Variability in scores between sites are due

mostly to true score variance• Differences between exam sites are in

magnitude of scores but not in pass/fail status

• Differences between assessors are mostly of magnitude of scores but not in pass/fail status

• Pass/Fails decisions did not vary between sites and assessors

• There is more variance between assessors than between exam sites

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Conclusions 1998-2004

• Development of cases should follow templates, guidelines and a detailed blueprint

• Selection of cases must follow a detailed blueprint to mirror OSCE forms between exam administrations to control for differences in cases such as complexity and content

Page 93: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Conclusions 1998-2004

• Multiple sources of errors in OSCEs forces us to do more extensive and non-traditional research than for MC exams

• OSCEs require continuous vigilance to assess the impacts of the many sources of errors

• OSCE research must be planned and implemented beyond exam administrations

Page 94: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Conclusions 1998-2004

• OSCE infrastructure must support both design research and exam administration research

• Successful implementation and continuous improvements of OSCE go hand and hand with research

• More collaborative efforts among OSCE users are needed to built on each other’s success and avoid pitfalls

Page 95: “Show Me How to Get Past MCQs: Emerging Opportunities in Measurement ” Carol O’Byrne, PEBC Karen S. Flint and Jaime Walla, AMP Drs. Frank Hideg, Paul Townsend,

Presented at the 2004 CLEAR Annual ConferenceSeptember 30 – October 2 Kansas City, Missouri

Conclusions 1998-2004

• Although OSCE research is costly it is a deterrent to litigation and wasted exam administration resources

• Similar conclusions may apply to other performance assessments
