Varimax – Simple Structure – Cluster Structure
In the pursuit of diverse trait indicators, it was important to distinguish true covariation between seemingly disparate response measures from chance patterns. It was required that each factor and each item identified as a factor marker be replicated in subsequent rounds of data analysis. Factor replicability was evaluated separately in both sexes with samples large enough (n > 250) to keep the probability of discarding good items tolerably low. Factor replication typically involved two stages: first, a subset of items consisting of established markers of each scale was factoranalyzed; this rarely resulted in item removals. Next, the remaining items, consisting largely of new candidates, were correlated with the replicated marker scales, and itemsshowing a good convergent-discriminant pattern in both sexes were retained.
To Balance (or not Balance) # T and # F Items
Although both true-keyed and false-keyedcandidate items were written for each scale, the scales were not required to contain an equal number of both (to have 'balanced’ keys). The critical attributes determining inclusion of an item were its convergent and discriminant correlational properties. It was not assumed, and it appeared not to be the case, that any given construct is representedequally well and 'naturally' by true- andfalse-keyed items.
TRIN and VRINResponse Aberrancy Assessment
An alternative to controlling (counter-)acquiescence is to measure it, so that problematic individual records can be identified. The true response inconsistency (TRIN) scale was constructed for that purpose. It is designed to detect the characteristic inconsistencies in response content that are the result of a (counter-) acquiescent style. TRIN is one of two MPQ inconsistency measures, the second being the variable-response inconsistency (VRIN) scale (for a discussion of TRIN and VRIN and of inconsistencyassessment generally, see Tellegen, 1988
