How self-compassion operates within individuals: An examination of latent profiles of state self-compassion in the U.S. and Japan. Mindfulness.
セルフ・コンパッションは個人内でどのように作用するのか：日米における状態セルフ・コンパッションの潜在プロフィールの検討
https://doi.org/10.1007/s12671-023-02143-2

Self-compassion is theorized to be a state of mind representing the balance of compassionate self-responding (CS; kindness, common humanity and mindfulness) and uncompassionate self-responding (UCS; self-judgment, isolation and over-identification) in times of distress. However, there is an on-going debate about this conceptualization, with some arguing that CS and UCS operate separately and independently. A variation on this view is that the operation of self-compassion differs by culture: In Eastern dialectic cultures like China and Japan, individuals are thought to experience CS and UCS simultaneously but not in Western non-dialectic cultures like the U.S. Our research investigated this issue by examining how state self-compassion operates within individuals in both the U.S. and Japan. We conducted latent profile analyses of state self-compassion both before (n = 855) and after (n = 455) a self-compassion mood induction designed to increase CS. In both cultures, individuals were classified into one of three latent profiles only: Low State Self-Compassion (low CS and high UCS), Moderate State Self-Compassion (moderate CS and UCS), and High State Self-Compassion (high CS and low UCS). We did not find any individuals with a profile characterized by simultaneously high levels of CS and UCS. This was true even after a self-compassion mood induction, although the distribution of people in the three profiles changed reflecting a simultaneous increase in CS and decrease in UCS. Results suggest that CS and UCS operate holistically and not independently within individuals in both dialectical and nondialectical cultures. This study is not pre-registered.

Does the Study of Culture Enrich Our Understanding of Autism? A Cross-Cultural Exploration of Life on the Spectrum in Japan and the West.
文化研究は自閉症への理解を深めるか？日本と西洋における自閉スペクトラムの生活についての文化比較

Autism spectrum condition is a neurodevelopmental condition in which people are characterized by their social differences. As such, autistic behaviors are often identified as deviating from what is considered normal or neurotypical ways of interacting with the world as dictated by a particular culture. This theoretical article explores a cultural model of disability concerning autism spectrum condition and how Western ideals of “normality” dominate autism-related discourses. To illustrate this point, the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association [APA]) descriptors are discussed concerning Western and, in contrast, Japanese cultural practices. Cross-cultural research from several domains reveals the subjectivity inherent to what is considered “normal” across cultures. In addition, research into the prevalence and lived experiences of autistic people and their families in Japan reveals the complexity of understanding neurodevelopmental conditions in non-Western countries. The article discusses autism in the context of culture and suggests further areas for cross-cultural research that can further build on the cultural model of disability.

自閉スペクトラム症とは，社会的な差異を特徴とする神経発達状態を指す。そのため，自閉行動は，文化によって定められた正常または定型発達的な「世界との関わり方」から逸脱しているとみなされがちである。この論文では，自閉症スペクトラム症に関連する障害の文化モデルを提案し，西洋的な「正常」概念がいかに自閉症関連の言説を支配しているかを明らかにする。この点を示すために，まず，DSM-5という世界的に用いられている精神障害の診断・統計マニュアルの記述について，西洋の文化的慣習と，またその対比として日本の文化的慣習とどう関連づけられるのかを議論する。続いて，いくつかの異なる領域における文化比較研究から，なにが「正常」とみなされるかには文化によって固有のばらつきがあることを示す。さらに，日本において自閉的な人やその家族がどの程度存在するのかというデータ，またその人たちの生きた経験から，非西洋圏において神経発達状態を理解する時の複雑さを明らかにする。この論文では，文化という文脈の違いから自閉症について議論し，障害の文化モデルの足場となりうるような，比較文化研究における今後発展可能な領域を示すものである。

The effects of seeing an older person who violated or observed prescriptive stereotypes on ageism.
高齢者への規範的ステレオタイプに反する/遵守する高齢者について知ることがエイジズムに及ぼす影響
International Journal of Gerontology, 17(2), 144-145.
https://doi.org/10.6890/IJGE.202304_17(2).0013

People generally exhibit ageism toward older adults that adversely affects the older adults’ health status. The prescriptive stereotypes held by younger individuals, such as succession (i.e., older adults should not accumulate wealth and pass it on to the younger generation), consumption (i.e., older adults should not receive more social security than they need), and identity (i.e., older adults should behave in an age-appropriate manner without trying to look young), account for the ageism. Moreover, if younger people see an older person violating such stereotypes, their ageism toward them will increase. We conducted an online experiment with young Japanese participants (N = 931). Each participant read one of the six vignettes about an older person who violated/observed the succession/consumption/identity aspect of prescriptive stereotypes. Results reveal that except for a single case involving the succession stereotype, other participants who read the vignettes of an older person violating prescriptive stereotypes did not exhibit more ageism than those who read the vignettes of an older person who observed the stereotypes. However, this result might be due to the inadequate sample size, and further research is required.

Acculturation attitudes and adaptation among South Korean residents in Japan: The mediating role of coping strategies. 
日本の韓国人ニューカマーにおける文化受容態度と適応： 対処戦略の媒介的役割
International Journal of Intercultural Relations. 
https://doi.org/10.1016/j.ijintrel.2023.101799

Acculturation processes and intergroup experiences of minority groups have been little studied in East Asian societies, including Japan. The number of migrants in Japanese society is steadily increasing, suggesting that the country is a new immigration destination in the 21st century. Therefore, further research on the acculturation processes of immigrants in Japan is warranted. This study examined the relationships among acculturation attitudes, coping strategies, and psychological adjustment in a sample of South Korean newcomers living in Japan. The results of this study support the integration hypothesis, which states that balanced acculturation attitudes that favor engagement in both the host and home cultures lead to higher levels of psychological and sociocultural adaptation. Assimilation attitudes did not contribute significantly to adaptation. Different coping strategies employed by individuals during interethnic discrimination mediated the links between individual acculturation attitudes and the two aspects of adaptation. By linking acculturation attitudes and relevant social behaviors, this study sheds light on the role of coping strategies as mediators of the relationships between acculturation attitudes and psychological and sociocultural adjustment in ethnic minority groups.

日本を含む東アジア社会では、マイノリティグループの文化変容の過程や集団間の経験はほとんど研究されていない。日本社会における移民の数は着実に増加しており、日本が21世紀における新たな移民先の一つであることを示唆している。したがって、日本における移民の文化変容の過程に関するさらなる研究が必要である。本研究では、日本に住む韓国人ニューカマーをサンプルに、文化変容態度、対処戦略、心理的適応の関係を検討した。本研究の結果は、統合仮説を支持するものであった。すなわち、ホスト文化と自文化の両方へ関与しようとするバランスのとれた文化変容態度は、より高いレベルの心理的・社会文化的適応をもたらすというものである。同化の態度は適応に大きく寄与しなかった。民族間差別の際に個人が採用する対処戦略の違いは、個人の文化変容態度と適応の2つの側面との間のリンクを媒介した。本研究は、文化変容態度と関連する社会的行動とを関連づけることで、民族的マイノリティにおける文化変容態度と心理的・社会文化的適応との関係の媒介としての対処戦略の役割に光を当てている。

Anti-old and anti-youth attitudes among older adults: Focusing on middle-aged and old age identity. 
高齢者が抱く、高齢者および若者への否定的態度：中年アイデンティティや高齢者アイデンティティに着目して
The Journal of Social Psychology, 163(2), 248-255.
https://doi.org/10.1080/00224545.2022.2061893

There is currently a lack of comprehensive scholarly information concerning the attitudes older people hold toward both older adults and the young. Using the social identity theory framework, this study investigated older identity issues including middle-aged identity and old age identity. We conducted an online survey of Japanese older participants (N = 301) and then implemented a Bayesian structural equation modeling to examine whether age and gender predicted middle-aged/old age identity in addition to whether middle-aged/old age identity predicted anti-old/anti-youth attitudes. Results showed the more strongly participants identified with being middle-aged the more positive their attitudes were toward old/young people, while they showed no significant relationship between old age identity and the attitudes. Regarding participant ages, the results found no significant relationship with middle-aged identity but a positive relationship with old age identity. These findings will contribute to psychological research aimed at reducing anti-old/anti-youth attitudes among older adults.

Attitudes toward possible food radiation contamination following the Fukushima nuclear accident: A nine-year, ten-wave panel survey.
福島第一原発事故による食品放射線リスクへの態度：9年10波パネル調査による検討 
Journal of Risk Research.
https://doi.org/10.1080/13669877.2023.2181856

After the Fukushima nuclear accident, we examined changes in risk perception regarding the radiation contamination of food and information-seeking behavior among residents of three regions progressively more distant from the disaster area, the Tokyo Metropolitan area to the Kansai area. We conducted a ten-wave panel survey and obtained data from 1,752 citizens six months to nine years after the accident. The results indicate that anxiety related to radioactive contamination, active information-seeking behavior, and avoidance of foods from affected areas decreased with time. Active information-seeking behavior and radiation-related knowledge were higher in the disaster-affected prefectures than in other areas. Conversely, avoidance of foods from affected areas was lower in affected prefectures than in the Kansai area. The credibility of government information increased from a considerably low level but did not reach the midpoint level. Multiple regression analysis, cross-lagged analysis, and structural equation modeling indicated that avoidance of foods from affected areas was promoted by anxiety related to radioactive contamination (experiential thinking/System 1) and inhibited by critical thinking attitudes (analytical thinking/System 2). Finally, we discussed the significance of risk literacy, which integrates risk-related knowledge, scientific literacy, media literacy, and critical thinking.

福島原発事故後、首都圏から関西圏へと被災地からの距離の異なる3地域の住民を対象に、食品の放射能汚染に関するリスク認知や情報探索行動の変化を調査した。10波パネル調査を実施し、事故から半年から9年後の市民1,752名からデータを得た。その結果、放射能汚染に関する不安、積極的な情報探索行動、被災地産食品の忌避が時間の経過とともに減少していたことが示された。積極的な情報探索行動や放射線に関する知識は、被災県で他の地域より高かった。逆に、被災地産食品の忌避は、関西圏よりも被災県で低下した。政府情報の信頼性は、かなり低い水準から上昇したが、中位水準には達しなかった。被災地の食品を避けることは、放射能汚染に関する不安（経験的思考/システム1）が促進し、批判的思考態度（分析的思考/システム2）が抑制している可能性が示された。リスクに関する知識、科学的リテラシー、メディアリテラシー、批判的思考を統合したリスクリテラシーの意義について考察した。

Paranoid thinking and perceived competitive intention. 
パラノイア思考と競争的意図
PeerJ, 11:e15003
https://doi.org/10.7717/peerj.15003

Paranoid thinking, that others are hostile, can be seen even in the general population. Paranoia is considered the expectation that others are competitors who aim to maximize the differences in payoffs rather than maximize their own payoffs. This study examined whether paranoia reflects the irrational belief that others have a competitive intention and is associated with avoiding perceived competition. We recruited 884 US residents via the Internet and conducted a modified Dictator Game, in which monetary allocation was carried out between the Dictator and the Recipient. The Dictator chooses either fair or competitive allocation while selecting the competitive allocation is irrelevant to increasing the Dictator’s payoffs. The Recipient decides whether to accept the Dictator’s decision or receive sure but low rewards. We found that Recipients with high-level paranoid thinking expected their opponent to select competitive allocation more than those with low levels, even when selecting it was costly for Dictators. Paranoid thinking was not associated with selecting sure rewards or competitive allocations. The results suggest that paranoia reflects the belief that others have a competitive intention but is not related to avoidance behavior against perceived threats and unilateral attacks.

The impact of television on-air time on hand hygiene compliance behaviors during COVID-19 outbreak. 
新型コロナウイルス感染禍における手指消毒遵守に及ぼすテレビ報道時間の効果
American Journal of Infection Control.
https://doi.org/10.1016/j.ajic.2023.03.001

Background
There is limited data to support the impact of the COVID-19 pandemic on hand hygiene compliance among hospital visitors.

Methods
We monitored hand hygiene compliance among university hospital visitors in Osaka, Japan by direct observation, from December 2019 to March 2022. During this time, we measured the amount of coverage time dedicated to COVID-19 related news on the local public television channel and the number of confirmed cases and deaths.

Results
Over 148 days, 111,071 visitors hand hygiene compliance was monitored. The baseline compliance was 5.3% (213 of 4026) in December 2019. From late January 2020, compliance rose significantly to almost 70% in August 2020. It remained at a level of 70% to 75% until October 2021, after which, the compliance slowly declined to the mid-60% range. The number of newly confirmed cases and deaths were not related to the change in compliance, but the association between the on-air time of COVID-19-related news and compliance was statistically significant.

Conclusions
Hand hygiene compliance dramatically increased following the COVID-19 pandemic. The role of television in increasing hand hygiene compliance was significant.

Popular names are given less frequently to babies in individualistic countries: Further validation of unique names as an indicator of individualism. 
個人主義的な国では人気のある名前が新生児に与えられる頻度が低い：個性的な名前が個人主義傾向を示す指標として妥当かに関する更なる検証
Current Research in Behavioral Sciences, 4, 100094. 
https://doi.org/10.1016/j.crbeha.2022.100094

A prior study showed that popular names are given less frequently to babies in individualistic countries in European, Anglo-American (North American), and Oceanian cultures. However, the samples of the previous study were limited, and it did not examine other cultures, leaving it unclear whether the relationship is still found even when other cultures are included. It is important to confirm validity of indices cross-culturally. Thus, the present study included two unexamined cultures in the analyses: East Asian culture and Latin American culture. Following the previous study, I calculated the rates of popular baby names in Japan and Puerto Rico, and examined how the addition of these two regions affected the results. Analyses showed that the negative relationships between the rates of popular names and individualism scores were still salient. Therefore, this study further confirmed the validity of unique names as an indicator of individualism in more diverse cultural contexts. / ヨーロッパ・北アメリカ・オセアニア文化圏における個人主義的な国では、人気のある名前が新生児に与えられる頻度が低いことを、先行研究は示していた。しかし、先行研究のサンプルは限定されており、他の文化を含めてもその関係が見られるか不明であった。指標の妥当性を文化横断的に検証することが重要である。よって本研究では、これまで検討されていなかった東アジア文化（日本）とラテンアメリカ文化（プエルトリコ）を含めて分析を行った。先行研究に従い、日本とプエルトリコにおける人気のある新生児の名前の割合を算出し、その2つの地域を含めることで結果がどのように変わるのかを検討した。分析の結果、人気のある名前の割合と個人主義得点には、負の関連が依然として見られた。そのため本研究は、名前指標が個人主義指標として妥当であることを、より文化的に多様な文脈において再確認したと言える。

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data.
