questions on life satisfaction flzm a short questionnaire for assessing subjective quality of life
European Journal of Psychological Assessment, 2000Co-Authors: Gerhard Henrich, Peter HerschbachAbstract:Summary: A short questionnaire for assessing general and health-related quality of life is presented. Test Construction and psychometric evaluation are described and recent findings obtained with the instrument reported and plans for developing additional modules outlined. Questions on Life SatisfactionModules (in the original German: FLZM, Fragen zur LebenszufriedenheitModule) combines three features: economy, modular structure, and individual weighting of items. The questionnaire consists of two 8-item modules, “General Life Satisfaction” and “Satisfaction with Health.” The respondent rates each items twice, once for the subjective importance of the aspects of life or health addressed, and once for the degree of satisfaction in that area. The two ratings are combined into a “weighted satisfaction” score. The total score is the sum of these eight scores. Norms for Germany and Spain have been established. Data for patients from different diagnostic groups in Germany are also available. The work in progres...

standards for the development and review of instrumental studies considerations about Test selection in psychological research
International Journal of Clinical and Health Psychology, 2007Co-Authors: Hugo Carreterodios, Cristino PerezAbstract:This paper discusses the criteria that should be considered when selecting psychological assessment Tests in a research context. Traditionally attention has focused - and still does - on the stages that must govern any process of Test Construction/ adaptation. This work is guided by internationally accepted standards, whose scientific importance is agreed by the scientific community. However, beyond any Construction/ adaptation process, the use of Tests is a constant feature of psychological research, so it is of vital importance to select the Tests adequately. For this reason, in this theoretical study we provide a summary of the criteria that should guide Test Construction/adaptation as well as some general guidelines to consider when selecting Tests for psychological research. The information presented is organized into six sections, each of which corresponds to a different stage in the process of Test creation: a) conceptual definition of the construct to assess; b) information about item Construction and qualitative assessment; c) results of the statistical analysis of the items; d) empirical evidence of the internal structure of the Test; e) results of the reliability estimation; and f) external evidence of score validity. The study ends with a reflection on the scope of the proposed guidelines and the importance of using clear criteria to select the Tests used in research.

environmental control on shell structure and composition of agglutinated foraminifera along a proximal distal transect in the marmara sea
Marine Geology, 2013Co-Authors: Eric Armynot Du Châtelet, Viviane Boutroumazeilles, Rodolfo Coccioni, Fabrizio Frontalini, Francois Guillot, Michael A Kaminski, Philippe Recourt, Armelle Riboulleau, Alain Trentesaux, Nicolas TribovillardAbstract:Abstract The study of benthic foraminifera in a complex marine system, like the Marmara Sea, is a key for understanding the influence of environmental factors on foraminiferal species, density, assemblage composition, and shell Construction. This kind of study is important for further extensive use of foraminifera-based investigation of water mass and sediment exchange between the eastern Mediterranean and Black Sea through the Marmara Sea. Based on proximal–distal transect from the southwest coast of the Erdek Bay to the top of canyon close to the North Anatolian Fault, this study aims at defining the geochemical conditions at the seafloor and identifying the sediment constraints that act upon agglutinated Test Construction for selected species (Eggerelloides scaber, Textularia agglutinans, Textularia sagittula, Textularia truncata and Textularia bocki). Grain size, mineralogical, and chemical analyses of their shells were investigated and confronted with the main geochemical conditions prevailing during deposition and within the sediment. Among grains used to construct the agglutinated foraminiferal Tests from available grains, both grain size selection and sorting have been evidenced. This suggests that the mineralogical composition is related to the species and the sample localization within the basin. Our observations further suggest that bottom water conditions of the Marmara Sea do not have a significant influence on agglutinated foraminiferal shell development, which is primarily driven by sediment characteristics. Our results are thus transposable to other environments.
