EBP#2 Chpt 14: Data Collection in Quantitative Research

Comprehensive vocabulary flashcards covering data collection methods, instrument types, response biases, and implementation strategies in quantitative research.

Structured Data

Data collected using formal instruments that place constraints on those collecting the data and those providing it.

Pretesting

The process of evaluating a data collection package to identify hard-to-read parts, offensive questions, sensible sequencing, and training needs.

Open-ended questions

Questions that permit respondents to reply in their own words in a narrative fashion.

Closed-ended questions

Also known as fixed-alternative questions, these offer response alternatives from which respondents must choose the one that most closely matches their answer.

Dichotomous questions

A specific type of closed-ended question that offers only two response options, such as yes or no.

Forced-choice questions

Closed-ended questions that require respondents to choose between two competing positions.

Rating questions

Questions that ask respondents to make judgments along a bipolar dimension.

Checklists

A type of closed-ended question format where several questions share the same response format.

Visual analog scales (VASs)

Instruments used to measure subjective experiences on a continuum.

Likert-type summated rating scales

Composite scales consisting of several positive and negative statements where respondents indicate their level of agreement or disagreement.

Mini-Mental Status Examination (MMSE)

An example of a neurophysiological test used in structured self-reporting.

Semantic differential (SD) scales

A specific type of structured self-report instrument used to measure attitudes or concepts.

Patient-Reported Outcomes Measurement Information System (PROMIS®)

A system used for collecting patient-reported data via methods like the internet.

Social desirability response bias

A type of response bias where participants provide answers that are more socially acceptable rather than their true feelings.

Acquiescence response set

Also known as Yea-sayers, this is the tendency of a respondent to agree with statements regardless of their content.

Nay-sayers

Respondents who tend to disagree with statements regardless of the content.

Time sampling

A sampling method for structured observations based on specific time periods.

Event sampling

A sampling method for structured observations focusing on specific occurrences or behaviors.

Halo effect

An evaluative bias encountered in structured observation where the observer's general impression of a person influences their specific ratings.

In vivo measurements

Biomarker measurements performed directly within or on a living organism.

In vitro measurement

Biomarker measurements performed outside of the organism, such as on a specimen in a laboratory.

6-Minute Walk Test (6MWT)

A specific physical performance test used to measure a client's endurance and mobility.

Data Extraction Blinding

The practice of ensuring record abstractors are unaware of study hypotheses or participant group membership to prevent bias.
