Kenji Yokotani, Tetsuya Yamamoto, Hideyuki Takahashi, Masahiro Takamura and Nobuhito Abe : Sounds like gambling: detection of gambling venue visitation from sounds in gamblers' environments using a transformer, Scientific Reports, 15, 1, 340, 2025. (Summary) Objective digital measurement of gamblers visiting gambling venues is conducted using cashless cards and facial recognition systems, but these methods are confined within a single gambling venue. Hence, we propose an objective digital measurement method using a transformer, a state-of-the-art machine learning approach, to detect total gambling venue visitations for gamblers who visit multiple gambling venues using sounds in gamblers' environments. We sampled gambling and nongambling event datasets from websites to create a gambling play classifier. We also sampled gambling and nongambling location datasets for a gambling location detector. Further, we sampled practical dataset with four different recording conditions and two different recording devices. Our Swin transformer model with 54 classes (4 gambling play classes and 50 nongambling event classes) achieved highest accuracy (0.801). The gambling location detector of the Swin transformer also achieved high performance; the areas under the receiver operating characteristic curves (AUCs) for bingo, mahjong, pachinko, and electronic gambling machine plays were 0.845, 0.780, 0.826, and 0.833, respectively. Moreover, gambling visitation detector of the Swin transformer showed high performance especially in Pachinko (AUCs 0.972-0.715) regardless of their recording conditions and devices. These preliminary findings highlight the potential of environmental sounds to detect visits to gambling venues.

(Summary) Electronic gambling machines (EGMs) in gambling venues cause gambling-related harm and are a public health concern. This study focused on pachinko parlours as gambling venues and income-generating crimes as gambling-related harm. We aimed to verify whether income-generating crime rates increase in proximity to pachinko parlours and during the opening and post-closing periods of pachinko parlours relative to the pre-opening periods.

10.	Kenji Yokotani and Masanori Takano : Avatars' Social Rhythms in Online Games Indicate Their Players' Depression., Cyberpsychology, Behavior and Social Networking, 25, 11, 718-732, 2022. (Summary) Data sets on gameplay, called digital biomarkers, contain many characteristics of game players and are associated with mental health problems. In fact, an avatar's behavior during an online game is said to be related to its player's mental health. Based on this information, we estimated the depressive state of players based on their avatar's behavioral logs. There were 3,361 participants who were players of Pigg Party, a popular Japanese online game application. In April 2020, the players logged into the Pigg Party and answered a questionnaire on depression. In May 2020, of the 3,361 participants, 658 players again logged into the Pigg Party and answered the depression questionnaire. Their responses to the questionnaire and behavioral logs of Pigg Party for April and May comprised the data sets used in the study. The data set from April showed that individuals without depression were more likely to perform activities in a 24-hour cycle than individuals with depression. Furthermore, the popular model of the time series data set trained on the April data set predicted depression in the May data set with an accuracy of around 0.3 to 0.4. The results suggest that these models are difficult to predict for sparse time series data sets, such as the study's data set, and require refinement.

(Summary) This study clarified the advantages of virtual communities on non-victim experiences among lesbian, gay, bisexual, transgender, questioning, intersex, and asexual (LGBTQIA) individuals in Japan. A total of 3504 Pigg Party users, including 1390 LGBTQIA individuals, reported their experiences of victimization, perceived emotional support, and concealment of their gender/sexual identity in both physical and virtual communities. Japanese individuals with multiple minority statuses had more victim experiences than those with a single or without minority status. Furthermore, differences in victim experiences by gender/sexual minority status were lower in the virtual community than in physical communities. Similar tendencies were also confirmed on perceived emotional support and concealment. Virtual communities provided a more bias-free social resource to Japanese LGBTQIA individuals than physical communities.

16.	Kenji Yokotani : A Change Talk Model for Abstinence Based on Web-Based Anonymous Gambler Chat Meeting Data by Using an Automatic Change Talk Classifier: Development Study., Journal of Medical Internet Research, 23, 6, e24088, 2021. (Summary) Change and sustain talks (negative and positive comments) on gambling have been relevant for determining gamblers' outcomes but they have not been used to clarify the abstinence process in anonymous gambler meetings. The aim of this study was to develop a change talk model for abstinence based on data extracted from web-based anonymous gambler chat meetings by using an automatic change talk classifier. This study used registry data from the internet. The author accessed web-based anonymous gambler chat meetings in Japan and sampled 1.63 million utterances (two-sentence texts) from 267 abstinent gamblers who have remained abstinent for at least three years and 1625 nonabstinent gamblers. The change talk classifier in this study automatically classified gamblers' utterances into change and sustain talks. Abstinent gamblers showed higher proportions of change talks and lower probability of sustain talks compared with nonabstinent gamblers. The change talk model for abstinence, involving change and sustain talks, classified abstinent and nonabstinent gamblers through the use of a support vector machine with a radial basis kernel function. The model also indicated individual evaluation scores for abstinence and the ideal proportion of change talks for all participants according to their previous utterances. Abstinence likelihood among gamblers can be increased by providing personalized evaluation values and indicating the optimal proportion of change talks. Moreover, this may help to prevent severe mental, social, and financial problems caused by the gambling disorder.

18.	Kenji Yokotani, Katsuhiro Tamura, Yusuke Kaneko and Eiichi Kamimura : Craving for Gambling Predicts Income-Generating Offenses: A Pathways Model of a Japanese Prison Population., Journal of Gambling Studies, 36, 2, 459-476, 2020. (Summary) The links between gambling and criminal offenses have been frequently reported, but the pathways from gambling to a particular offense have not. Our study applied a pathways model to predict participants' income-generating, drug-related, and violent offenses stemming from their craving for gambling. The participants were 332 male inmates in a Japanese local prison. They answered questionnaires on gambling behavior, alcohol addiction, Internet addiction, impulsivity, and psychopathy. Their official records with information on their current offense, sentence length, number of imprisonments, and length of education were also analyzed. The results show that 38.55% (n = 128) of the participants had a probable gambling disorder, a rate of problem gambling at least four times higher than that among the general Japanese population. Furthermore, their craving for gambling predicted their income-generating offenses, but not their drug-related and violent offenses. Their craving for gambling can thus be linked to their financial issues, rather than their emotional and impulsive issues. The pathways model explained the path not only from addiction/psychopathy to gambling, but also from gambling to committing an income-generating offense.

(Summary) Addiction is serious problem that requires effective treatment. Previous studies support personalized feedback interventions (PFIs) as an effective treatment for drinking; however, the potential beneficial effects of this treatment on illegal drug use have not been explored. The present study examined the effects of PFIs in a sample of repetitive drug-related offenders. Participants were 50 repetitive drug-related offenders incarcerated in a Japanese prison. They were randomly assigned to the PFIs (n = 20) or control (n = 30) group. The PFIs group received six letters for 3 months, whereas the control group did not undergo any interventions. We defined relapse and recidivism as drug-related reoffending and reentering prison after release, respectively. In the 3.6-year follow-up analysis (range, 0.1-5.8 years), participants' criminal records were examined, and results indicated a decreased risk of relapse and recidivism for the PFIs group relative to the control group, even when controlling for age, educational level, number of prison terms, and sentence length. Thus, our findings suggest that PFIs reduce the likelihood of relapse and recidivism in drug-related offenders.

(Summary) <p>Couples cope with their stress as a unit rather than two isolated individuals. Couples coping were well examined by the Dyadic Coping Inventory (DCI) in European and American population, but not in Asian population. We aim to examine the applicability of DCI in Japanese married couples. Participants were 44 heterosexual couples in Japan. They answered the DCI and marital satisfaction. Results supported the applicability of DCI generally and showed several partner effects. The partner effects of DCI were discussed from the perspective of perceived social support.</p> (Keyword) couples coping / dyadic coping / Japanese / marital satisfaction (Link to Publication Site) ● Publication site (DOI): 10.2117/psysoc.2015.155 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390282680088530048 ● Search Scopus @ Elsevier (DOI): 10.2117/psysoc.2015.155 (DOI: 10.2117/psysoc.2015.155, CiNii: 1390282680088530048)

(Summary) The aim of the present study is to investigate reliabilities and validities of the Japanese version of the Communication Patterns Questionnaire (CPQ). Participants were 76 married women and 55 married men. They answered questions regarding their marital satisfaction, their orientation toward divorce, and the CPQ. Results suggested that almost all CPQ scales reached the same levels of reliability as previous studies. The CPQ also had significant relationships with participants' marital dissatisfaction and orientation toward divorce. These results were regarded as empirical evidence concerning the application of the CPQ to Japanese couples.

(Summary) The effect of educational level on employment of people with high functioning autism spectrum disorders (HFASD) was examined. If education augments natural abilities to accomplish tasks in people with HFASD, then those with more education would have comparative advantages in both obtaining and retaining jobs. In contrast, if education did not augment natural abilities and only signaled unobservable abilities, one would expect an advantage only in obtaining a job, but not in retention. 22 people with HFASD replied to questionnaires regarding their history of education and employment. Those with job experience had higher educational levels than those with no job experience, but educational level was not significantly different between groups with and without more than one year of job experience. Educational level seems to be associated with abilities, but probably the unobserved abilities underlie both educational attainment and employment history.
