Comparisons
UKPQ scales correlate with their equivalents in the OPQ®, ranging from R = 0.80 (Warmth)
to R = 0.68 (Assertiveness). They correlate with their equivalents in ASE PeopleMapper,
ranging from R = 0.82 (Work Oriented) to R = 0.62 (Detail-Consciousness). They correlate
with their equivalents in 16PF-5, such as the scale for 'Openness to Experience'
(R = 0.73). They correlate with the OPP, such as the scale for 'Assertiveness' (R
= 0.74) and Optimism (-0.65 with 'Pessimism').
Each scale correlates highest with the scale whose conceptualisation most closely
matches itself. Some correlations were found to exceed 0.8, and all but two exceed
0.68. By comparison, the OPQ ® 5.2 shows correlates with the 16PF that range from
0.70 to 0.19
UKPQ Validity
The UKPQ's validity was - of course - extremely important to the test designers,
and it demonstrates its validity and utility in terms of its construction and its
predictive capability. The UKPQ began with a search for personality constructs with
practical importance to the UK workplace in the middle-to-late years of the first
decade of the 21st century. This effectively defined the broad domains of the questionnaire,
and items were written to be content valid within those domains. In other words,
the items directly address attitudes or behaviour related to the construct under
consideration.
A total of 525 items were written, and after internal analysis, a total of 368 were
chosen for the initial statistical analysis exercise conducted within various industry
sectors within the UK. The 368 items were administered to around 1000 employees in
the healthcare, retail, manufacturing, wholesaling, professional and service sectors,
together with other well-regarded instruments that, together, covered the broad spectrum
of items contained within the UKPQ. From the analysis, each question was carefully
correlated against its own scale, and also all other scales. No item was successful
if it correlated more highly with another scale than its own, irrespective of the
degree of correlation reported with its own scale. The question bank was reduced
from 368 to 199. Still further evidence comes from the correlation of the UKPQ with
other well-known tests as described in the technical manual. The tests were chosen
because of the similarity between their scales and those of the UKPQ. Click here
