This article concerns the question of journal impact factor and other
bibliometric indicators made available by the Institute for Scientific
Information in their Journal Citation Report for 1996. The impact factors
of journals within the subject category 'substance abuse' are listed along
with total citations, immediacy indices, and cited half-lives. The
relationship between cited and citing journals is discussed with the main
focus on the data available for Alcohol and
Alcoholism. Some of the problems and limitations of bibliometric
measures of productivity are dealt with, especially when these are used to
evaluate the work of individual scientists. Although bibliometric measures
are easy to compute, they become difficult to interpret, such as when
dealing with collaborative research and the problem posed by multiple
authorship. The need to adjust impact factors and citation counts for the
number of co-authors in a paper becomes important when credit has to be
attributed to one individual from a multi-author paper. This is often
necessary in connection with grant applications and when making decisions
about academic promotion and tenure. The impact factor of Alcohol
and Alcoholism has increased steadily over the past 5 years,
even after adjusting for the number of self-citations, which resulted in an
even greater increase in impact. However, the impact factors of substance
abuse journals are generally low, compared with disciplines such as
immunology, genetics, and biochemistry. Some suggestions are made for
increasing the impact factors of substance abuse journals if this is
considered necessary. But instead of paying attention to the impact factor
of a journal, scientists should give more consideration to the speed and
efficiency of the editorial handling of their manuscripts and particularly
to the quality and timeliness of the peer review.
