Although there are psychometric evaluations of the Revised Conflict Tactics Scales (CTS2) when applied to heterosexual relationships, none has used item response theory (IRT). IntroductionThe increase in family violence has generated a growing body of research on the development of measurement tools, including the class of instruments known as Conflict Tactics Scales 1,2,3,4,5,6,7 . These are based on 'conflict theory' and aim to identify strategies used by individuals to solve disagreements and impasses 8,9 . The first instrument in the series (CTS1) was proposed in the late 1970s and sought to address any kind of violent relationship 10 . Despite its encouraging evaluations over the years and successful use in at least 20 countries 3,11,12,13,14,15 , a more refined instrument was subsequently developed for dealing exclusively with intimate partner violence. The Revised Conflict Tactics Scales (CTS2) was presented in 1996 and consists of 39 items forming five scales, namely negotiation (6 items), psychological aggression (8 items), physical violence (12 items), sexual coercion (7 items), and injury (6 items) 13 .The CTS2 has been studied since its release. Results show acceptable reliability, validity, and a factor structure in tune with the underlying theory 13,16,17,18,19 . However, when focusing on intimate partner violence in heterosexual couples, such psychometric evaluations have exclusively used classical test theory 20 . In order to address this gap, the aim of the present paper is to provide a more in-depth item analysis than is possible with traditional psychometric procedures.ARTIGO ARTICLE Reichenheim ME et al. 54

“…In the first stage the assumption of unidimensionality is tested by a partial-credit Rasch model (Masters, 1988;Masters and Wright, 1984;Rost, 1996) within one latent class. The same response categories from 'seldom/never' to 'almost all the time' are employed for all items, so measurement models for ordered categories can be applied.…”

Scale development is a major part of the work of industrial and organizational psychologists (e.g., developing selection tests or employee attitude surveys), and item analysis is an essential aspect of this process. Item analysis attempts to address "the problem of selecting items for a test, so that the resulting test will have certain specified characteristics" (Gulliksen, 1950, p. 363).In this chapter we demonstrate how to conduct an item analysis using two psychometric frameworks: classical test theory (CTT; Gulliksen, 1950) and item response theory (IRT; Lord and Novick, 1968). Methodology based on IRT (sometimes known as modern test theory or latent trait theory) is relatively new to I-O psychologists. Embretson and Reise have commented on recent changes in psychometrics:Although classical test theory (CTT) has served test development well over several decades, item response theory (IRT) has rapidly become mainstream as the theoretical basis for measurement. Increasingly, standardized tests are developed from IRT due to the more theoretically justifiable measurement principles and the greater potential to solve practical measurement problems. (2000, p. 3) These authors demonstrate how some old rules of measurement based on CTT have been revised or made obsolete by IRT. IRT enables us to solve some problems (e.g., test equating, detecting differential item functioning (DIF), and developing computer adaptive tests) that were difficult or impossible to address with CTT. In terms of item analysis, IRT is more difficult to apply, but offers some advantages over CTT alone. Thus, we advocate that the CTT and IRT approaches be combined in conducting an item analysis. Throughout this chapter, we have tried to present a balanced picture of the advantages and disadvantages, both practical and psychometric, of using CTT and IRT in conducting an item analysis. The remainder of the chapter is divided into the
