Abstract

Objectives
This study examined the research trends in the field of the five addictions, examining the correlations and co-occurrence among addiction studies.
Methods
Bibliographic information from papers was used to examine the correlations and cooccurrence between different fields of addiction. The analysis covered the entire period and specific time frames. Correlation analysis was conducted using cosine similarity, while co-occurrence analysis was performed using text network analysis.
Results
An analysis of the correlations and co-occurrence among the five addictions revealed the following. First, since 2000, studies on internet and smartphone addiction have become more active, leading to a significant increase in research connections between the different types of addiction. Second, there is a high correlation between alcohol addiction and internet addiction, with shared research topics being actively explored. Finally, the most commonly addressed topic across studies on the five addictions is adolescent addiction.
Conclusion
The significance of this study lies in its contribution to understanding the trends in addiction-related research and the insights into the treatment of cross-addiction.
