We searched 5 electronic databases (PubMed, Embase,
Popline, National Library of Medicine Gateway, Cochrane Library) to identify studies of IPT published in English, French, or Spanish from 1951 to October 2003.
Medline,
Popline, and Health Star were searched from January 1980 to August 2000 using the terms "pregnancy in adolescence," "parents," and "program evaluation." The Psych Info database was searched using the terms "adolescent mothers," "adolescent pregnancy," and "program evaluation." Two investigators independently reviewed the results of each search to identify articles that were potentially eligible for inclusion.
To identify relevant studies in both developing and developed countries, we undertook an extensive search using databases (i.e.,
Popline, Medline and Population Index) and available bibliographies.
Lexus/Nexis, Medline,
Popline, Uncover, and other electronic literature data bases have replaced the Reader's Guide to Periodical Literature and the Social Science Index as the starting points for undergraduate and graduate research papers.
