1

Where is data collection found?

Methods section of the article.

2

Rule of thumb

"Garbage in, garbage out" If you make poor measurements, you're going to get bad results

3

Pretest tools. Why?

Performs as expected
Ease of administration
Time commitment
Subject understanding

4

Data/datum

Data is plural, datum singular

5

Instrument/tools

Different word, same thing

6

Remote indicator

how to measure something.
Example: A way to measure pain...facial expression, body language

7

Standardized instrument

An instrument (or tool) that has been checked for reliability/validity, always will work the same

8

Subscale

Take a general topic, break it down

9

Explicit

As accurate as possible

10

Widely applicable

Applies to the general population

11

Orderly

Tidy flow...visually aesthetic

12

Specific

Specific to topic...
Example: DEPRESSION, not anxiety or sadness

13

Realistic

Time appropriate, cost appropriate

14

Structure

High(forces subject to pick a specific answer), middle, low(open ended questions)

15

Quantifiability

Ability of data to be recorded by numbers

16

Obtrusiveness

To what extend does the subject know they are being observed/assessed

17

Objectivity

To what extend are the results subject to bias

18

Descriptive/Exploratory Design

Observational checklist - unique to this design
Questionnaire - very popular
Scale

19

Correlational/Quasi-Experimental/Experimental/Clinical Trial

Questionnaire
Survey
Biophysical

20

Biophysical Measurement...why use?

Relevance to nursing (BP, HR, Temp, Lab values...etc)
Impact of nursing actions
Evaluate nursing procedures
Find health related correlations

21

Biophysical Measurements need to be...

Appropriately collected, recorded, stored, tested, and reported

22

Psychosocial Measurements
Self Reports

Interviews, written questionnaires, etc

23

Psychosocial Measurements
Observations

Checklists, observational rating scales

24

Likert-type

5-7 points
Ex: strongly agree, agree, undecided, disagree, strongly disagree

25

Visual Analog Scale (VAS)

0-100mm
100mm line, subject places vertical line on scale based on their answer.

26

Semantic differential

Forced choices, range
Ex: range of sad to happy, five blank lines, place check mark saying how happy you feel.

27

Q-sort

agree/disagree
Sort index cards into piles...agree/disagree, then agree/strongly agree; strongly disagree/disagree

28

Projective techniques

Appropriate for right brained people/children
Ex: Ink blots, pictures, music. Opinions are projected on the image

29

Criteria when examining tools

Appropriate (to question/design/population)
Feasible
Acceptable to subject
Reliable and valid

30

Measurement Errors

Need to reflect as much truth as possible in our measurements
