FCTs are generally composed by blocks of items with different items measuring different dimensions (Multidimensional, MFCTs) or the same dimension (Unidimensional, UFCTs).
Empirical evidence shows that MFCTs, to some extent, can control response biases (e.g., Cheung & Chan, 2002; Saville & Willson, 1991), increase criterion validity (Bartram, 2007; Brown & Maydeu-Olivares, 2013), and avoid or reduce faking (Christiansen et al., 2005; Heggestad, Morrison, Reeve, & McCloy, 2006; Hirsh & Peterson, 2008; Jackson, Wroblewski, & Ashton, 2000).
To gain insight into how normative information can be extracted from MFCTs, two approaches have been followed.
Most operational MFCTs have been elaborated with dominance items (Brown & Bartram, 2009; Brown & Maydeu-Olivares, 2010) as they are based on classical test theory, where item selection criteria advise to discard nonmonotonic (ideal point process) items because they are characterized by low or negative item-total correlations or weak factor loadings.
Apart from the differences between the DM and UM, importantly, the pattern of results turns out to be largely the same for both models: (a) EAP correlate higher with the true scores than TS do; (b) the RANK and MOLE format yielded quite similar results, as the PICK and PAIR formats do, and the results for the former were clearly better than for the latter; (c) MFCTs with more blocks, consisting of a mix of positive and negative items that have high discrimination parameters result in estimates that better predict the true scores; and, finally, (d) the effect of the intra-block variability among the items' difficulties was negligible.
TA: AIPDC is 100% owned by the MFCT. We report directly to the minister of the FCT and our work cuts across all the departments and agencies in the ministry.
We are presently recruiting top class management personnel in order to rebuild the manpower base of the company, and we will engage in more training to ensure that the human resources' capacity we have within the AIPDC will be able to handle other important tasks for the MFCT.
