Background: The use of objective measurement via Rasch models in self-report scales has increased in the recent past, which in turn has enabled the development of computer adaptive tests (CATs). Despite significant advances in both objective measurement and computer adaptive applications few studies have ventured into the personality domain and the emergent field of emotional intelligence. The development of CATs of personality attributes holds advantages such as the reduction in items used for the assessment, reduction of respondent fatigue, and greater cooperation from respondents in the assessment. Research purpose: The aim of this study was to develop a computer adaptive test of the trait Self-control sub-scale of a trait-based emotional intelligence inventory (Trait Emotional Intelligence Questionnaire: TEIQue). Secondary objectives were to examine the functioning of the CAT by (a) comparing the CAT with a static version, and (b) to establish a practical approach to developing a computer adaptive solution to existing static fixed format self-report inventories. Research design: Participants were 681 working South African adults who participated in a local validation research project of the TEIQue. All respondents completed an informed consent form indicating willingness to participate in the research process. The self-control scale consists of 31 items. Each item employs a 7-point Likert-type response format. The data analysis entailed three steps. Step 1 focussed on establishing a benchmark based on the static measurement of trait based self-control. The analysis entailed calibrating and composing a core self-control item bank by means of a Rasch rating scale analysis. The Rasch analysis focussed on how well the observed data fitted the measurement model and identifying items that meet the criteria for inclusion into the item bank. The data were analysed for individual item fit, unidimensionality, local independence, and differential item functioning across gender. Items that did not meet the criteria for good fit were excluded from the item bank. The rating scale analysis yielded 16 items that met the requirements of the Rasch model. These items constituted the static item bank. Step 2 involved obtaining person measures and standard errors for the static item bank. Step 3 involved a post hoc CAT simulation of the responses of the 681 persons to the 16 items, where different item selection criteria and stopping rules were applied to obtain CAT based person measures and standard errors. All simulations were carried out with the Firestar software. The aim of this step was to evaluate the correspondence between static person measures (i.e. measures obtained with the full item bank) and adaptive person measures (i.e. measures obtained with the simulated CAT). Main findings: Overall, high correlations were found between person measures of the static inventory and the CAT version. With a 13 out of 16 item strategy a very high correlation (r = .97) was obtained. The 7 out of 16 item strategy yielded a satisfactory, but somewhat weaker result (r = .91). Results showed that on average about ten items were required to obtain a standard error of person measures < .40. Different initial item starting and subsequent item selection strategies yielded largely similar results with no one single strategy clearly appearing to be the best strategy.
