Starting from the observation that data sharing in general and sharing of reusable behavioral data in particular is still scarce in psychology, we set out to develop a curation standard for behavioral psychological research data rendering data reuse more effective and efficient. Specifically, we propose a standard that is oriented toward the requirements of the psychological research process, thus considering the needs of researchers in their role as data providers and data users. To this end, we suggest that researchers should describe their data on three documentation levels reflecting researchers’ central decisions during the research process. In particular, these levels describe researchers’ decisions on the concrete research design that is most suitable to address the corresponding research question, its operationalization as well as a precise description of the subsequent data collection and analysis process. Accordingly, the first documentation level represents, for instance, researchers’ decision on the concrete hypotheses, inclusion/exclusion criteria and the number of measurement points as well as a conceptual presentation of all substantial variables included in the design. On the second level these substantial variables are presented within an extended codebook allowing for the linkage between the conceptual research design and the actually operationalized variables as presented within the data. Finally, the third level includes all materials, data preparation and analyses scripts as well as a detailed procedure graphic that allows the data user to link the information from all three documentation levels at a single glance. After a comprehensive presentation of the standard, we will offer some arguments for its integration into the psychological research process.

Stability and change in students' achievement goals (AGs) are of great relevance for educational research and practice. In two separate meta-analyses, we investigated the rank-order stability (93 studies, 569 effect sizes, 54,736 students), as well as the mean-level change (157 studies, 1,170 effect sizes, 81,464 students) in AGs throughout students' academic careers (K-12 to university). We found that the average rank-order stability of AGs ([rho] = 0.51) was in the approximate range of rank-order stability reported for personality traits and other motivational constructs. Stability increased with students' grade level and decreased with increasing interval duration between measurement points. Overall, the mean levels of all AGs declined throughout K-12 (Glass's [delta] ranged from -0.15 to -0.06 per year), indicating a quantitative decrease in AGs throughout this academic stage. During the university years, only mastery-approach goals significantly declined ([delta] = -0.22 per year), indicating a qualitative decrease in AGs.
