This study continues to develop and test an integrated conceptual model of journal citation impact. The main objective is to obtain a more complete understanding of how and to what extent the external factors affect journal citation impact. Four external factors have been identified from previous studies: journal properties, journal accessibility, journal internationality and perceived journal quality. A conceptual model of journal citation impact is developed and a web-based survey is conducted for obtaining information on the perceived journal quality. Structural equation modeling (SEM) with partial least squares (PLS) is used to test the conceptual models with empirical data from 41 research journals in clinical neurology. Interrelationships among journal citation impact and the four external factors have been successfully explored. The results also suggest that, for an integrated conceptual model of journal citation impact, various citation indicators should be used.
