European Journal of Personality publishedto occupy a distinctive portion with the target construct's variance. It uses an alternative representation with the construct to assess whether or not a measure's facets fulfil this common criterion. Prior to describing the system in detail, it is essential to specify its unique focus and explain how it supplements existing test construction approaches. We then proceed with a short overview on the construct of trait emotional intelligence (trait EI), on which the system will be applied within the present investigation. Equivalent to definitions frequently applied in the literature (Costa McCrae, 1995; Smith, Fischer, Fister, 2003), we use the term facet to refer to a variable representing a narrow and very homogenous subset of affective, behavioural, or cognitive tendencies connected with a offered construct. Facets are interrelated and define the hypothetical domain of a construct; their prevalent variance is conceptualized as representing the construct of interest. We make use of the term issue to designate a variable that subsumes the frequent, construct-related variance of a number of facets. Elements offer a mid-level in between facets and the latent construct, serving to organize the facets into subcategories and providing the basis for subscales.Rationale and focus: Redundant and extraneous facets The psychometric literatures of quite a few constructs suggest that the contemporary scale-construction approaches.F Personality published by John Wiley Sons Ltd on behalf of European Association of Personality Psychology. Crucial words: scale construction and improvement; facets; psychometrics; assessment; trait emotional self-efficacy; TEIQueExamining the literature of an individual-differences construct, a single typically finds a diversity of measures, with an all round abundance of facets. Even individual measures composed of a fairly massive quantity of facets are rather typical. In some situations, the arrays of facets employed to represent precisely the same construct diverge considerably (in quantity and/or varieties), and correlations involving their composites are weak or moderate (e.g. Baer, Smith, Hopkins, Krietemeyer, Toney, 2006; Brackett Mayer, 2003). It is then tough to accept that all measures reflect the identical underlying attribute to a comparable degree. This rather messy state reflects the lack of adequate criteria for defining psychological constructs, which are only indirectly inferable and measurable (Cronbach Meehl, 1955). Therefore, researchers have noted that there is considerable uncertainty in determining the set of facets and models from which the composite representative of the targeted attribute is often derived (e.g. Petrides Furnham, 2001). The present post describes and applies a brand new psychometric technique for creating and optimizing multi-faceted measurement instruments. Since scale development goes hand-in-hand with all the development of construct representations (e.g. structural models), in addition, it has implications for the latter. The strategy is intended to supplement the contemporary theoretical and empirical approaches to scale construction, by targeting `problem' facets detrimental to construct validity.
