Assignment notes

Steps for assignment

1. Definition

2. Blueprint

There is also a supplemental reading on the test specification/blueprint (primarily pages 211-216, 218 rating scale, 221-224) which should help you better understand test specification /blueprint.

3. Nomological Net

Do not use content areas as correlations

ie. Use big 5 traitr outer option but not inner

Grit in middle (like mind map) and big 5 trait,

related but distinct construct ie IQ, academic performance, needs to 1 big 5 trait, impulsivity

must have relationship to GRIT (can be negative relationship)

include the figure

From tute slides:

Draw a small (3- 4 constructs) nomological network for your construct, indicating direction of relationship

Include references for these relationships

Include as a Figure + brief supporting text in your assignment

From this, select a BIG 5 construct to use to check the validity of your scale

Find a short, psychometrically sound scale to measure that 2nd construct to include in your questionnaire

Short 5-12 item scale, should be reliable Cronbach’s > .7

Tutor said this week to focus on working out which big 5 trait

Put in definition or methods section

DEscribe like scale from 1st year,

You will need to describe this additional BIG 5 construct and scale in your paper

Tip from tute

When selecting a related construct to use for your test of construct validity, you should :

Investigate the literature, and see what other theoretically related constructs have been identified.

Tips include a Google Scholar search for the name of your construct (GRIT), and words like correlated, phrases like “GRIT is correlated with” or “GRIT is associated with”.

You should select a BIG5 construct that will maximise your chances of demonstrating construct validity. Avoid trivial correlations like .1 .2, etc.

e.g. empathy is weakly associated with one of the Big 5, openness ~.22 (Mooradian, Davis, and Matzler)

But a GoogleScholar search will outline that empathy is strongly correlated with Big 5 agreeableness, so this might be a better choice.

4. Demographics

You will need to measure a few (approx. 3- 5) demographic items in your questionnaire

Gender

Describe sample

Test bias in the items

Age

Essential to describe your sample

Any other demographic details that might be relevant:

Are you a university student?

Anything relevant to correlations ie. GPA

To describe your specific sample adequately (what might be relevant descriptors)

Should be able to fit all on one short page of questionnaire
