Abstract
The purpose of this study was to examine the internal reliability, factorial validity, and measurement invariance of a Brazilian-Portuguese version of the General Health Questionnaire-12 (GHQ-12) across clinical and nonclinical groups. The clinical sample consisted of 228 chronic hemodialysis patients (41.7% female), with a mean age of 48.23 (SD = 16.02) years, whereas the nonclinical sample comprised 350 university students (59.1% female), with a mean age of 21.15 (SD = 2.04) years. Initial model fit comparison of 16 factor structures reported in the literature, through confirmatory factor analysis (CFA), provided mixed results. Additional revisions based on CFA modification indices demonstrated that a reduced (8-item) one-factor model with three error covariances provided the best fit to the data in both samples (comparative fit index > .98 and root mean square error of approximation < .05) and acceptable internal reliability estimates (>.70). Pearson's correlations between the original and the reduced scale was .96 for both samples. Multigroup analysis supported partial strong measurement equivalence across groups. Latent mean differences showed an expected higher factor mean for the clinical sample. Overall results demonstrated that the 8-item one-factor of the GHQ-12 showed good psychometric properties in both samples and provided preliminary support for meaningful comparisons of factor means across clinical and nonclinical groups.

Abstract
The motivational orientation of an athlete aims to improve their skills (task) and getting a good result in a given competition (ego). Thus, the purpose of the present study was to compare players of one Portuguese team handball club. The independent variables were: competitive levels, years as competitors, time presence as player in the club and competitive position. The dependent variables were motivational orientations: task and ego. The sample consisted of 57 male athletes borne between 1977 and 1997. The Task and Ego Orientation Questionnaire in Sport (TEOSQp), validated by Fernandes and Vasconcelos-Raposo (2010) was used. Results revealed that the handball players in the club studied present high scores on both task and ego orientation with a higher score at the level of task orientation. The present results are not in accordance with previous studies. However they do not contradict consolidated theoretical proposal. Senior athletes presented higher scores in task orientation and lower on ego. Comparisons by years in competition, time presence in the club and competitive position in the do influence significantly the motivational orientation among this club team handball players.

Creating and using software documentation presents numerous challenges, namely in what concerns the expression of knowledge structures, consistency maintenance and classification. Adaptive Software Artifacts is a flexible approach to expressing structured contents that tackles these concerns, and that is being realized in the context of a Software Forge.
