Clinical and research interest is growing in mental health support for elite athletes, based on findings from epidemiological surveys conducted in Australia, the United States, and European countries. However, little is known about the mental health status of elite athletes in Asia, including Japan. In the current study, we examine the prevalence of mental health problems and suicidal ideation and its risk factors in Japan Rugby Top League players. We analyze anonymous web-based self-reported data from 251 currently competing Japan Rugby Top League male players. During the off-season from December 2019 to January 2020, data on anxiety and depression symptoms were collected using the Japanese version of the 6-item Kessler-6. Suicidal ideation was assessed using the Baron Depression Screener for Athletes. Among the players, 81 players (32.3%) had experienced symptoms of mild anxiety and depression during the previous 30 days, while 12 (4.8%) and 13 (5.2%) had suffered from moderate and severe symptoms, respectively. Nineteen athletes (7.6%) reported that they had experienced suicidal ideation during the previous 2 weeks. Players with mental health problems experienced more events in competitions and daily life, including reduced subjective performance, missing opportunities to play during the last season, changes in health condition, and thinking about a career after retirement, compared with players without such problems. Mental health issues in Japan Rugby Top League players, as elite athletes, may be common, and research and practice development is expected in the near future.

The Baron Depression Screener for Athletes (BDSA) is a brief, valid, and reliable athlete- specific assessment tool developed in the US to assess depressive symptoms in elite athletes. We examined the applicability and reliability of a Japanese version of the BDSA (BDSA-J) in a Japanese context, and further examined the construct validity of the BDSA-J. Web-based anonymous self-report data of 235 currently competing Japanese professional male rugby players (25–29 years = 123 [52.3%]) was analyzed. A two-stage process was conducted to validate the factor structure of the BDSA-J using exploratory factor analysis in a randomly partitioned calibration sample, and confirmatory factor analysis in a separate validation sample. Cronbach’s alpha was used to assess internal consistency. Spearman’s rank-order correlation coefficients were calculated to examine convergent validity with the Kessler-6. We identified a one-factor structure for BDSA-J. Confirmatory factor analysis supported this one-factor model, revealing good model fit indices. The standardized path coefficients for each of the items were β = 0.52 to 0.79 (p < 0.001). A Cronbach’s alpha of 0.71 was obtained for the BDSA-J. BDSA-J showed significant positive correlations with the Kessler-6. The BDSA-J is an appropriate and psychometrically robust measure for identifying depressive symptoms in Japanese male rugby players.

Background Globally increasing clinical and research interests are driving a movement to promote understanding and practice of mental health in elite athletes. However, few studies have yet addressed this issue. This study aims to describe the association of the intention to seek help with mental health knowledge and stigma and the severity of depressive symptoms in Japan Rugby Top League players. Methods As a target population, we studied 233 Japan Rugby Top League male players (25–29 years = 123 [52.8%]), who were born in Japan, using a cross-sectional design. Surveys were conducted using anonymous, web-based self-administered questionnaires. Structural equation modelling was performed to evaluate the hypothesis of an interrelationship between mental health knowledge, stigma, and severity of depressive symptoms as factors influencing the intention to seek help. Results Players with more severe depressive symptoms were more reluctant to seek help from others (β = - 0.20, p = 0.03). Players with greater knowledge about mental health tended to have less stigma toward others with mental health problems (β = 0.13, p = 0.049), but tended not to seek help with their own mental health problems. Conclusions Rugby players in need of mental health support, even with greater knowledge, tend not to seek help from others, while having less stigma toward people with mental health problems. Rugby players might require approaches other than a knowledge-based educational approach to encourage them to seek help.

Objectives: The primary objective is to compare the prevalence of mental health problems, including psychological distress, anxiety and depressive symptoms in Japan Rugby Top League players in the new life with COVID-19 with those evaluated before COVID-19.Methods: An observational comparative web-based cross-sectional study was employed for Japan Rugby Top League players. We compared the data from 220 Japanese and 7 foreign players during the new life with COVID-19 with the data from before COVID-19, which was obtained from 233 Japanese and 18 foreign players. We measured anxiety and depression symptoms with the validated Kessler-6, which has been widely used in clinical and research settings among different populations. To investigate the distribution of K6 score and whether there are discrete clusters or not, we conducted the two-step cluster analysis.Results: In the new life with COVID-19, 15.0% of players reported mild symptoms, which was significantly lower than the 32.3% of players before COVID-19. The prevalence of moderate and severe symptoms was 6.7 and 3.5%, respectively, in the group during the new life with the COVID-19, and 4.8 and 5.2% in the pre-COVID-19 group, with no significant difference. A two-step cluster analysis supported the existence of these two qualitatively different clusters in both groups.Conclusions: With the spread of new lifestyles related to COVID-19, some rugby players may have improved mental health status due to changes in their daily living environment. Such environmental adjustments alone may not have been sufficient to change the mental health status of others. Rugby players or their teams may require mental health professionals and systems that ensure rest, adjust the environment, and sustainably provide more professional care.

Background There is increasing international interest in clinical practice and research related to mental health in the international sports society. The athlete-specific psychological distress assessment tool that addresses potential mental health needs can help promote early detection and recovery of mental illness, as well as physical illnesses. Currently, little is known about the applicability of the useful assessment tool for Japanese elite athletes. The Athlete Psychological Strain Questionnaire (APSQ) is a brief, effective and reliable screening tool to identify early signs of athlete-specific distress and potential mental health symptoms. We examined the applicability and reliability of a Japanese version of the APSQ (APSQ-J) in a Japanese elite athlete context. Further, we examined the construct validity of the APSQ-J. Methods We collected web-based anonymous self-report data from 219 currently competing Japanese professional male rugby players. A two-stage process was conducted to validate the factor structure of the APSQ-J using exploratory factor analysis (EFA) in a randomly partitioned calibration sample and confirmatory factor analysis (CFA) in a separate validation sample. Cronbach’s alpha is used to assess internal consistency. Pearson product-moment correlation coefficients were calculated to determine if the APSQ-J was significantly associated with measures of psychological distress and well-being using Kessler-6 (K6) and the WHO-5 Well-Being Index, respectively. Results We identified a one-factor structure for the APSQ-J. Confirmatory factor analysis supports this one-factor model, revealing good model fit indices. The standardized path coefficients for each of the items were β = 0.41–0.83 (p < 0.001). A Cronbach’s alpha of 0.84 was obtained for the APSQ-J. The APSQ-J demonstrated significant correlations with the K-6 (r = 0.80, p < 0.001) and WHO-5 (r = −0.58, p < 0.001). Conclusion The APSQ-J can be an appropriate and psychometrically robust measure for identifying athlete-specific distress in elite athletes in Japan. Widely disseminating and utilizing this scale in Japanese sports society may support athletes' mental health via early detection of symptoms of psychological distress.
