The main purpose of this study is to assess the factor structure and the measurement invariance of the Mini-International Personality Item Pool (Mini-IPIP; Donnellan, Oswald, Baird, & Lucas, 2006). The Mini-IPIP is a brief instrument evaluating personality traits according to the Big Five models. Two samples were collected comprising nearly 800 participants. Confirmatory factor analyzes reveale...

This note clarifies aspects of impulse invariance and, in particular, the handling of multiple-order poles. The user is currently faced with incorrect formulas and Matlab software. The problems are discussed, and a method valid for any order poles is presented via a numerical example using original Matlab code.

This study tested for measurement invariance of VandeWalle’s (1997) goal orientation instrument across Korean and American workers using multi-group confirmatory factor analysis. Across groups, learning and proving orientations were invariant, but avoiding goal orientation was partially noninvariant. Implications for goal orientation and comparisons between Korean and American respondents are d...

Within the theoretical framework of achievement goals (Nicholls, 1989), Duda and Nicholls (see Duda, 1989; Duda & Whitehead, 1998) developed the Task and Ego Orientation in Sport Questionnaire (TEOSQ) to assess individual differences in achievement goal orientations. This study searches for validity evidence of the TEOSQ in the case of Spanish (2473) and Portuguese (2486) junior high school. Th...

The analysis of measurement invariance of latent constructs is important in research across groups, or across time. By establishing whether factor loadings, intercepts and residual variances are equivalent in a factor model that measures a latent concept, we can assure that comparisons that are made on the latent variable are valid across groups or time. Establishing measurement invariance invo...

a r t i c l e i n f o Keywords: Customer value Relationship value Formative and reflective value models Crosscountry measurement equivalence This commentary reflects on Blocker's cross-cultural investigation of relationship value in business markets, published in this issue, and identifies several research avenues. From a theoretical point of view, researchers should develop and test hypotheses...

Researchers often compare groups of individuals on psychological variables. When comparing groups an assumption is made that the instrument measures the same psychological construct in all groups. If this assumption holds, the comparisons are valid and differences/similarities between groups can be meaningfully interpreted. If this assumption does not hold, comparisons and interpretations are n...
