Assessment and Evaluation Flashcards

Which type of assessment uses a stopwatch-timed walk test and measured grip strength rather than participant self-report?

Answer: Performance-based outcome measure

Performance outcomes are based on standardized tasks the participant actively performs.

When a validated English questionnaire is used with Spanish-speaking participants, what is the recommended approach?

Answer: Use a formally translated and culturally adapted version, typically developed with forward-back translation

Formal translation with forward-back translation and cultural adaptation preserves the instrument's validity.

The smallest change in a score that participants perceive as meaningful is known as what?

Answer: Minimal clinically important difference (MCID)

The MCID is the smallest score change considered meaningful to patients or clinicians.

On a Likert scale, what kind of data does each individual item's response (e.g., strongly disagree to strongly agree) represent?

Answer: Ordinal

Likert item responses are ordered categories without guaranteed equal spacing, making them ordinal.

An assessment's ability to detect true change in a participant's condition over time is called what?

Answer: Responsiveness

Responsiveness, or sensitivity to change, is an instrument's ability to detect real change over time.

An assessment is completed outside the protocol-defined visit window. What should the research assistant do?

Answer: Record the actual date and report the deviation according to study procedures

Accurate dates must be recorded and protocol deviations reported per GCP and study procedures.

Participants answer survey questions in a way they think will be viewed favorably by staff. What bias is this?

Answer: Social desirability bias

Social desirability bias occurs when respondents give answers that make them look good rather than accurate ones.
