The number of publications in this area is growing, but it is difficult to conduct precise searches due to a lack of clear terminology. To facilitate retrieval, bibliographic databases should include descriptor terms referring specifically to Internet, video games, and cell phone addiction as well as to more general addictions involving communications and information technologies and other behavioral addictions.

PsycINFO is useful for making comparisons between countries, because it includes the name and country of the institution. The number of publications in the EU on alcohol and drug misuse increased over the quarter-century analysed. The most used language was English, as it also is for PsycINFO as a whole, and a tendency towards its increased use was observed. Classification of the articles by subject by the Classification Code is too general, and makes it difficult to distinguish between the areas it proposes. Production tends to be concentrated in journals dealing specifically with drug dependence and psychiatry. The index of collaboration is similar to that found in other scientific areas.

Pain in neonates was a neglected subject of publication until the mid-1980s, and, currently, only a few countries seem interested in this type of pain. This lack of interest may be related to the undertreatment of pain in the neonatal period.

Background:The goals of the present work were to retrieve the scientific articles published on addiction to the Internet, video games, and cell phones and to analyze the pattern of publications in this area (who is doing the research, when and where it is taking place, and in which journals it is being published), to determine the research being conducted as well as to document geographical trends in publication over time in three types of technological addictions: Internet, cell phones, and video games.Methods:Articles indexed in PubMed and PsycINFO between 2006 and 2010 related to the pathological use of Internet, cell phones, and video games were retrieved. Search results were reviewed to eliminate articles that were not relevant or were duplicates.Results:Three hundred and thirty valid articles were retrieved from PubMed and PsycINFO from 2006 to 2010. Results were compared with those of 1996–2005. The year with the highest number of articles published was 2008 (n = 96). The most productive countries, in terms of number of articles published, were China (n = 67), the United States (n = 56), the United Kingdom (n = 47), and Taiwan (n = 33). The most commonly used language was English (70.3%), followed by Chinese (15.4%). Articles were published in 153 different journals. The journal that published the most articles was Cyberpsychology and Behavior (n = 73), followed by Chinese Journal of Clinical Psychology (n = 27) and International Journal of Mental Health and Addiction (n = 16). Internet was the area most frequently studied, with an increasing interest in other areas such as online video games and cell phones.Conclusions:The number of publications on technological addictions reached a peak in 2008. The scientific contributions of China, Taiwan, and Korea are overrepresented compared to other scientific fields such as drug addiction. The inclusion of Internet Gaming Disorder in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition could change the publication trends in the technological addiction area and underline the relevance of this upcoming disorder in dissatisfaction with life in general.

RESUMEN.La investigación es susceptible de ser evaluada de la misma manera que lo son otras actividades intelectuales y profesionales. Se presentan unas consideraciones acerca de la evaluación concreta de la investigación en las ciencias sociales, en contraste con las evaluaciones habituales de las ciencias experimentales y de la salud. Los indicadores son múltiples pero su uso para evaluar las ciencias sociales merece algunas consideraciones. Se expone una bibliografía comentada que cubre un amplio espectro de sociología y política de la ciencia y la tecnología con un énfasis en los aspectos de evaluación.La búsqueda de indicadores para evaluar la calidad, impacto y evolución de la investigación ha tomado una importancia creciente en los últi-mos años tanto en los países occidentales como en los países del Este de Europa 1 . Un repaso a la literatura lleva a listar los indicadores comúnmen-te aceptados por su utilidad o repercusión en las políticas sectoriales, consecuencia de una investigación social que siempre se puede analizar a nivel individual o de grupo de investigación:* VII Encuentro CIS-Universidad, Granada, 13 de diciembre de 1991. 1 Se agradece a la Secretaría General del Plan Nacional de la CICYT la financiación del proyecto PBS90-0160. Gracias a las sugerencias de Montserrat Jiménez, Josep A. Rodríguez y Jesús M. de Miguel y a la transcripción de Eva Perelló. Reís56/91 pp. 219-237
