Grit has recently attracted the attention of researchers and practitioners. However, studies have reported inconsistent findings regarding its dimensionality and association with success outcomes. This study examined the reliability and construct validity of a new Japanese translation of the Short Grit Scale (Grit-S-J), a brief self-report measure of grit, in a sample of 276 Japanese college students (88 women, 188 men; mean age = 20.81 years, SD = 0.89). Exploratory and confirmatory factor analyses supported the two-factor structure comprising perseverance of effort and consistency of interests. The total Grit-S-J and its two subscales showed adequate internal consistency and 4-week test–retest reliability. Construct validity was supported by expected correlations with scores for personality traits (self-control, Big-Five personality traits, and vitality), hedonic and eudaimonic well-being, and mental health (psychological stress, depression, and anxiety). Meanwhile, discriminant validity of the Grit-S-J was suggested by partial correlations between scores on the Grit-S-J, well-being measures, and mental health measures, after controlling for scores for either self-control or conscientiousness. Overall, the findings preliminarily support the usefulness of the Grit-S-J in grit research in the Japanese population.

Total pages：253 Responsible for pages：3-14 Language：eng Book type：Scholarly book
Although numerous forgiveness measures have been developed, only a few are useful for assessing the value of forgiveness. This study examined the reliability and construct validity of the Japanese translation (ATF-J) of the six-item Attitudes Toward Forgiveness Scale to assess individuals’ value of forgiveness. The participants were 234 Japanese college students (39.3% women; mean age = 20.85 years, SD = 1.27) who completed the questionnaire on two occasions separated by four weeks. The one-factor structure of the ATF-J was confirmed through exploratory and confirmatory factor analysis. Internal consistency reliability (Cronbach’s αs = .71 and .73) and test–retest reliability over a 4-week period (r = .61) were acceptable. Construct validity was supported by the expected correlations with scores for dispositional forgiveness of others, hedonic and eudaimonic well-being, psychological stress, trait empathy, and trait anger. However, contrary to expectations, no significant correlations were found between ATF-J scores and depression and anxiety symptom scores. Overall, these findings provide preliminary support for the reliability and construct validity of the ATF-J. Therefore, the ATF-J is a useful tool for assessing the value of forgiveness in the Japanese population.

Katsunori Sumi, Akiko Sumi（ Role： Contributor , Need support and need satisfaction in Arabic language classes in Japanese universities from the viewpoint of self-determination theory）
Springer 2023.12 （ ISBN:9789819955701 ）
Total pages：389 Responsible for pages：175-191 Language：eng Book type：Scholarly book
According to the self-determination theory, teachers’ support for the satisfaction of students’ basic psychological needs is valuable in promoting students’ well-being. However, most Japanese university teachers, especially Arabic language teachers, seem to perform support behaviors to facilitate student motivation and achievement in class rather than their well-being. This study mainly aimed to examine the influence of Arabic language teachers’ support (need support) on Arabic language students’ satisfaction (need satisfaction) in Japanese universities using longitudinal data. Additionally, a new measure to assess Arabic language students’ perceived need support was created. The results of the analysis of the data from 324 Arabic language students showed a positive relationship between perceived need support and further need satisfaction. The results also provide preliminary support for the new scale of perceived need support as a reliable and valid measure. Limitations of the study, directions for future research, and implications for Arabic language teachers’ need support are discussed.

Responsible for pages：27-37 Language：eng Book type：Scholarly book
As a brief measure of trait forgiveness of others, the Tendency to Forgive Scale (Brown, 2003) has been widely used in research. The purpose of the present study was to provide preliminary reliability and construct validity data on the translation of the Tendency to Forgive Scale into Japanese (TTF-J). Data were collected from 320 Japanese college students (38.1% women; mean age 20.82 years, SD = 1.11). The one-factor structure of the TTF-J was confirmed with exploratory and confirmatory factor analyses. Both internal consistency reliability and test-retest reliability over a 4-week period were acceptable. The construct validity of the TTF-J was supported by the expected correlations with scores for hedonic and eudaimonic well-being, self-esteem, depression, anxiety, trait empathy, and trait anger. The findings of this study generally supported that the TTF-J is a useful measure of trait forgiveness of others.

The trait scale of the Subjective Vitality Scale (Ryan & Frederick, 1997) is a widely used self-report measure of subjective vitality as a characteristic of the individual. However, certain problems with two items included in the measure have been pointed out. Therefore, three versions with different items are currently used in research (i.e., the 7-item, 6-item, and 5-item versions). This study aimed to develop and validate a new Japanese translation (SVS-J) of these versions using a sample of 424 Japanese college students. Exploratory and confirmatory factor analyses supported the unidimensionality of the three versions. However, the one-factor structure provided a better fit to the data for the 5-item version than for the other versions. All the versions showed good internal consistency reliability (Cronbach’s alphas = .87 to .91) and test-retest reliability (rs = .79 to .80). The expected correlations with scores on the hedonic and eudaimonic well-being, self-esteem, and mental illness measures were found to be common to the versions, confirming the convergent validity of the SVS-J. These findings show little evidence of problems with items, indicating that the choice of version may be insignificant. The versions were shown to be reliable and valid trait scales of subjective vitality and to have almost the same utility.

Total pages：300 Language：eng Book type：Scholarly book
This study aimed to examine the influences of demographic factors on orientations for learning Arabic among Arabic major students. The demographic factors studied included sex, academic year, period of learning Arabic, and the experience of having stayed in Arab regions. The participants were 261 Arabic major students at a Japanese university. They completed a questionnaire, namely, the 15-item Orientation for Learning Arabic Scale, which assesses five types of orientation: integrative, instrumental, friendship, travel, and knowledge orientations. There were several statistically significant demographically based differences between the various groups of Arabic students with regard to the types of orientation for learning Arabic. In general, sex and the experience of having stayed in Arab regions had weaker influences on the orientations, whereas academic year and period of learning Arabic had greater influences on them. The female students had higher friendship and knowledge orientations than did the male students. Arabic major students who had stayed in Arab regions had a greater desire to obtain knowledge about the Arabs than did those who had never stayed in an Arab region. On the other hand, it was found that, in general, the lower the academic year or the shorter the period of learning Arabic, the greater was the orientation for learning Arabic. In the future, it would be desirable to compare the influences of demographic factors on the orientations of Arabic major students with those of non-Arabic major students, who account for a higher proportion of Arabic learners at Japanese universities.

The present study developed and validated a new 9-item measure called the Basic Psychological Need Satisfaction of Arabic Learners Scale (BPNSALS). This scale was designed to assess the satisfaction of three basic psychological needs (i.e., autonomy, competence, and relatedness), which is central to self-determination theory (SDT), of Arabic learners in Japan. A total of 314 students taking Arabic courses in Japanese universities participated in a study to examine the reliability and construct validity of the BPNSALS. Both exploratory and confirmatory factor analyses of the BPNSALS items confirmed the subscale structure corresponding to the three basic psychological needs. Each BPNSALS subscale displayed adequate internal consistency (Cronbach’s alpha) and temporal stability over 4-week period. The construct validity of the BPNSALS was provided by support for the hypothesized relationships with the different forms of Arabic learning motivation as proposed by SDT. In addition, the self-determination of motivation and Arabic learning outcomes, namely, satisfaction, subjective comprehension, and subjective achievement were also considered. Based on the findings, the study concluded that the BPNSALS is a useful tool for assessing basic psychological need satisfaction of Arabic learners in Japan.

Arabic has been taught in formal education in Japan for the past 90 years. Arabic instruction is mainly conducted within the sphere of higher education in Japan, where the most important L2 (i.e., second language) is English. This chapter is an investigation of both the history of Arabic teaching and learning in Japan, and an analysis of the current situation. For data, official statistics, data originally obtained by inquiry, and original survey data were used. Also, we include parts of the authors’ previous studies. The focus is core issues concerning the actual condition of Arabic instruction in Japan, and a discussion of the strengths and limitations of current practices. Future directions in the field are also proposed.

Life is a series of coping with a variety of problems. Major or minor problems arise for us all the time, and our life is filled with them. These problems make incessant demands on us to treat and solve them. Thus, we need to engage constant problem-solving in daily life. Real-life problems vary in difficulty in solving, from extremely easy for anyone to eternally unsolvable. When coping with solvable problems, our ability to solve such problems is of great import. In this chapter, the ability for solving problems in our day-to-day lives, called social problem-solving, is addressed.

第8章 ストレスの発生と解消─測定尺度にみるストレス評定と対処─
企業・組織にとって，従業員のストレスによる損失は深刻な規模に達しており，ストレスのマネジメントは大きな課題となっている。ストレスほど常に私たちの身近にありながら，姿を現すことなく，社会の安寧と個人の幸福を脅かしているものはない。人の背後に取り憑いて離れず，執拗に命を狙い続ける─ まさにストレスは社会に公然とはびこる幽鬼といえよう。ストレスの発生と解消に関する十分な理解は，現代の企業・組織，そしてすべての個人にとって必須である。
この章では，主に知覚されたストレスと対処の測定方法を紹介することで，ストレスの発生のメカニズムと解消の方法について理解を深めることを目的としたい。
そこで，まずストレスの理解と対策の重要性を再確認するために，ストレスによる社会的，経済的損失に関する最近の試算結果を紹介する。次に，ストレスのメカニズムを簡単に整理しながら，その発生と解消の鍵となるストレス評定（stress appraisal）とストレス対処（stress coping）について説明する。そして，ストレス評定と対処の詳細について，それらを測定するための尺度を具体例として参照しながら，解説をおこなう。また，日常語として使用されるストレスや対処に関する語句の意味についても触れていく。なお，ここで「ストレス評定」は「ストレスを評定すること」を意味するものではない点に注意してほしい。 -
