Neuropsychopharmacology is an international scientific journal and the official publication of the American College of Neuropsychopharmacology (ACNP). This journal focuses upon clinical and basic science contributions that advance our understanding of the brain and behaviour, especially as related to the molecular, cellular, physiological and psychological properties of agents acting within the central nervous system and the identification of the new molecular targets for the development of the next generation of drugs. While original reports are preferred, mini-reviews and perspectives are invited by the editorial office.

Impact Factor

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?

III. Other Science Influence Indicators

Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
