Future direction of addiction research-An expert questionnaire survey in Japan.

ABSTRACT: Addiction has become a major worldwide medical, public health, and social problem. Because the prevalence of addiction varies widely geographically, due to differences in ethnicity, culture, education, social environment, and regulation, each country or region needs to understand its current state of addiction and to take appropriate measures, in multidisciplinary collaboration. In order to understand the direction of addiction research in Japan, we analyzed 50 research and development topics and their characteristics, based on an expert questionnaire survey. The topics were placed in five categories, as follows. Category 1: Basic science; all 10 topics were of the Long-term project and International cooperation types. Category 2: Translational and clinical research; 6 out of 10 topics were of the Long-term project. Category 3: Fact-finding surveys; 8 out of 10 topics were of the Japan-specific type. Category 4: Health system and service; 8 out of 10 topics were of the Japan-specific type and Short-term project. Category 5: Study on society, culture, environment, education, and regulation; 7 out of 10 topics were of the Short-term project (similar to Category 4). As far as we know, this is the first systematic questionnaire survey on the direction of addiction research. The results of this study might support developing a strategy for addiction research, not only in Japan, but also in other countries.

Project description:BackgroundsInternet addiction (IA) has become a major public health issue worldwide and is closely linked to psychiatric disorders and suicide. The present study aimed to investigate the prevalence of IA and its associated psychosocial and psychopathological determinants among internet users across different age groups.MethodsThe study was a cross-sectional survey initiated by the Taiwan Suicide Prevention Center. The participants were recruited from the general public who responded to the online questionnaire. They completed a series of self-reported measures, including Chen Internet Addiction Scale-revised (CIAS-R), Five-item Brief Symptom Rating Scale (BSRS-5), Maudsley Personality Inventory (MPI), and questions about suicide and internet use habits.ResultsWe enrolled 1100 respondents with a preponderance of female subjects (85.8%). Based on an optimal cutoff for CIAS-R (67/68), the prevalence rate of IA was 10.6%. People with higher scores of CIAS-R were characterized as: male, single, students, high neuroticism, life impairment due to internet use, time for internet use, online gaming, presence of psychiatric morbidity, recent suicide ideation and past suicide attempts. Multiple regression on IA showed that age, gender, neuroticism, life impairment, internet use time, and BSRS-5 score accounted for 31% of variance for CIAS-R score. Further, logistic regression showed that neuroticism, life impairment and internet use time were three main predictors for IA. Compared to those without IA, the internet addicts had higher rates of psychiatric morbidity (65.0%), suicide ideation in a week (47.0%), lifetime suicide attempts (23.1%), and suicide attempt in a year (5.1%).ConclusionNeurotic personality traits, psychopathology, time for internet use and its subsequent life impairment were important predictors for IA. Individuals with IA may have higher rates of psychiatric morbidity and suicide risks. The findings provide important information for further investigation and prevention of IA.
