3 facet rating scale: Creativity (with Excel input data file)

In a study commissioned by the US Navy (J.P. Guilford, 1954, Psychometric Methods, 2nd Ed., New York: McGraw-Hill, p.282, and MFRM Chapter 10), three senior scientists rated seven junior scientists on five traits of creativity. Ratings ranged from 1 to 9, with 9 meaning most creative.

 

Facets specifications and data (in file Guilford.txt):

 

Title = Ratings of Scientists (Psychometric Methods p.282 Guilford 1954)

; measurement model

Facets = 3  ; three facets: judges, examinees, items

Non-centered = 1 ; examinees and items are centered on 0, judges are allowed to float

Positive = 2  ; the examinees have greater creativity with greater score

Model = ?B,?B,?,Creativity ; judges, examinees and items produce ratings on "Creativity".

 ; A bias/interaction analysis, ?B,?B,?, will report interactions between facets 1,

 ; senior scientists (judges,) and 2, junior scientists (examinees).
