The purpose of this article is to analyze the evolution of the International Journal of Psychology & Psychological Therapy (IJP&PT) throughout its first decade of publication (from years 2001 to 2010), comparing the quality measures that result from applying the three most important social science databases: Thomson-Reuters Web of Science, Elsevier-Scopus, and Google Scholar. We compared the three databases, using the citations recorded for IJP&PT as a �case study� applied to a journal. As quality indicators we used IJP&PT data available in the three databases, as well as other indicators related to the internationality of the journal. The results shows a increasing tend in all quality criteria during the time period evaluated as a first-level journal among psychology journals edited in Spain. Also, the results shows serious discrepancies when the data of the three databases are compared. We discuss the need to improve the criteria used by the databases, as well as the convenience to use several quality indicators for journals� evaluation
