Report of Psychological Competitive Ability of Rugby Players in Each Unit Who Belong to Companies

The purpose of this study is to clear their psychological athletic ability by comparison between members and non-members as Team and Units, and also to assess the different of the psychological ability between elite rugby players and collegiate athletes and collect those data. This study conducted a survey on psychological-competitive ability of rugby players who belong to companies with a focus on members and non-members in a whole team in-cluded both Backs (BK) and Forwards (FW), or each unit. Comparison between these players and collegiate players was also carried out and their differences were clarified. The results of the survey showed that the members’ scores of “Judgment” and “Strategic ability” were higher than the non-mem-bers’ scores. The comparison with the collegiate players indicated that the elite players’ scores of “Self-control”, “Ability to relax”, “Concentration”, and “Mental stability and concentration” were higher than the collegiate players’ score as well as the collegiate players’ scores of “Volition for winning” and “Volition for competition” were higher than the elite players’ scores. These results suggested that rugby players need decision making skills in the game situations and these psychological skills such as “Judgment” and “Strategic ability” are important in selection criteria of members and coaching guidelines even for the players who belong to companies.


Purpose of This Study
The purpose of this study is to clear their psychological athletic ability by comparison between members and non-members as Team and Units, and also to assess the difference of the psychological ability between elite rugby players and collegiate athletes and collect those data. Based on this assessment, making a plan to improve psychological ability for their future and linking this to how we coach athletes are important as well.

Literature Review
Not only rugby players but also other athletes need basic physical ability, skills, and specific physical ability and skills for each sport, which are required for them to perform better in the game with their own talent. Zushi (2014) showed that coaches and trainers can clear their goals and problems, choose their exercise or drills with limited time, and make a plan and execute them by understanding their goal of Sports performance very well and assess them properly. It is very important to do assessment from those aspects. Trainers and Coaches assess their ability by doing tests regularly in off-season, pre-season and in season, and having training matches. Based on the assessment, they plan to develop athletes' ability. It is clear recently that not just physical and skills ability but also psychological ability is very important to develop and execute those abilities.
Assessing psychological ability regularly is very important as much as assessing physical ability, or performance to improve athletes' ability systematically and efficiently. Takeno et al. (2014) studied the relationship between psychological competitive ability and athlete's performance in Soccer and Volleyball. They reported that a team with higher psychological competitive ability has better athletic performance in both sports. Therefore, assessing psychological competitive ability is very helpful to check their current athletic performance.
Researchers overseas used psychological ability assessment such as MTQ48 (Clough et al., 2002), and they pull out mental toughness and provide it as mental ability, which is seen in a controlled environment such as competitive sports (Nicholls et al., 2009).
Other psychological ability assessments for athletes were developed. One is, the Athletic Mindfulness, which was recently developed by Amemiya et al. (2015). Also other diagnostic inventory of psychological competitive ability for athletes such as DIPCA.3, was developed and improved by Tokunaga (2001). It consists of five factors and twelve lower scales and used to survey a lot of sports.
Enda et al. used this test and surveyed collegiate athletes. They reported that athletes who were more talented showed higher psychological competitive ability.
There is some research, which used DIPCA.3 for surveying Rugby Football Team. The research by Terada et al. (1996) and Yonechi (2001) used high school athletes as their participants. There is the research by Okamoto et al. (1998) whose participants were collegiate athletes, and also Okamoto et al. (1996)  year of careers as players, or as international players.

Participants
The study involved 39 elite male rugby players, all belonging to teams in Japan

Survey and Research Term
Surveys were done in the 2018 season (Sep-Nov 2018). The team filled out the Ethical consent form before surveys were done. In addition, the elite rugby teams participated in this study as private organizations in order to get an outside evaluation of them, thus giving their players the opportunity to freely ex-

press their views without having to consider coaches. Given these conditions, in accordance with Japanese rule on ethics, the material contained in the report can be used to compile an article.
If they had less than 12 points in Lie Scale, we planned to eliminate the data.
But we could not find any data which was less than 12 points in Lie Scale.
We gave feedback of their individual results to all players to improve their ability.

Statistics
Each 12 lower scales and 5 factors of DIPCA.3 was used for analysis, and independent variables of the 2 groups were analyzed by T-test. The independent variables of more than 3 groups were analyzed by one-way analysis of variance. If significant variables were found, those variables were tested by Tukey. Statistical level was 5%. IBM SPSS Ver. 25 was used for statistical analysis.

Unit: FW vs BK
Independent Sample t-test was used to analyze the relationship of Psychological ability. Table 1 showed the relationship of Psychological ability as Units between Forward (FW) and Backs (BK).
As a Team, no significant differences were found in any factors and in lower scale between FW and BK.

Unit: Members vs Non-Members
Independent Sample t-test was used to analyze the relationship of psychological ability between "members" and "non-members" in a team. Table 2 showed the analysis of 2 groups in a team such as "members" and "non-members". It showed "members" were significantly higher than "non-members" in "Judgment (p < .05)" and "Strategic ability (p < .05)".
Independent Sample t-test was used to analyze the relationship of psychological ability between "members" and "non-members" in each unit. Table 3 and Table 4 showed the analysis of 2 groups in each unit such as "members" and "non-members". It showed that "FW (members)" was significantly higher than "FW (non-members)" in "Predictive ability (p < .05)", "Judgment (p < .001)", and "Strategic ability (p < .001)". No significant differences were found in any other factors and lower scale.  Also, no significant differences were found in any factors and lower scale between "BK (members)" and "BK (non-members)".
One-way analysis of variance was used to analyze the relationship of psychological ability among 4 groups. Table 5 showed comparison of 4 groups such as "FW (members)", "FW (non-members)", "BK (members)" and "BK (non-members)". It showed that "FW (members)" and "BK (members)" had significantly higher scores than "FW (Non-members)" in "Judgment (p < .05)" and "Strategic ability (p < .05)". Table 6 showed the comparison by using One Sample t-test between the results of this research ("elite players") and the study by  which targeted collegiate rugby players' psychological abilities.

Comparison with Collegiate Players
About 5 factors, elite players had significantly higher scores than collegiate players in "Confidence (p < .05)", "Mental stability and concentration (p < .01)".

Unit
There is no significant difference between FW and BK on the team in 5 factors and 12 lower scales. This result showed a contrast from research by  which said that BK was significantly higher than FW in "Decision" and "Strategic ability". We might be able to say that there is no difference between FW and BK in this team in "Decision" and "Strategic ability".
On the other hand, when we made a comparison between members and non-members, members had a significantly higher score than non-members in "Decision" and "Strategic ability". These results showed that understanding rugby and details of tactics were essential factors when coaches selected players for the games in this team. Psychology When we looked at the results between members and non-members in FW, it showed that members had a significant higher score in "Predictive ability" and "Judgment" in 12 lower factors, and "Strategic ability" in 5 Factors. These results showed that coaches looking at their "Predictive ability" and "Judgment" which come from understanding rugby and details of tactics, and "Strategic ability" which is a factor of these scales when they selected members for a game on this team.
On the other hand, there is no significant difference between members and non-members in BK. This result showed that the standard of member selection for BK is different from FW. Coaches were looking at their "Predictive ability", "Judgment" and "Strategic ability" for FW member selection, but the BK coach was looking at other factors as a standard of member selection for BK.
Research by Okamoto showed that BK is significantly higher than FW in "Predictive ability", "Judgment" and "Strategic ability". These showed that BK has training to improve those abilities in regular training, or that players who have aptitude for those abilities are playing rugby as BK.
When we compared 4 groups of "FW (members)", "FW (non-members)", "BK (members)", and "BK (non-members)", "FW (members)" and "BK (members)" had higher scores than "FW (non-members)" in "Judgment" and "Strategic ability". As mentioned previously about differences in teams and between members and non-members in a unit, non-members in FW, had less understanding of tactics and strategies in this team. Coaching understanding of tactics and strategies to non-members in FW is very important to improve the whole team.

Comparison between Elite Players and Collegiate Players
About 5 factors, elite players had significantly higher scores than collegiate players in "Confidence" and "Mental stability and concentration". On the other hand, collegiate players had significantly higher scores than elite players in "Volition for competition".
About the 12 lower scales, elite players had significantly higher scores than collegiate players in "Confidence", "Self-control", "Ability to relax", "Concentration", and "Decision". On the other hand, collegiate players had significantly higher scores than elite players in "Volition for winning". Also, collegiate players had a higher tendency than elite players in "Volition for self-realization".
Elite players had higher scores than collegiate players in "Mental stability and concentration" and lower scale of factors such as "Confidence", "Self-control", and "Ability to relax", and "Concentration". These results were matched with not only the study by Takizawa et al. (2018), which reported that experienced players had higher scores in "Self-control" and "Mental stability and concentration", but also Study by Takenouchi & Oohata (2015), which reported accomplishment of psychological development task are related to psychological ability very much. Even this study showed that experience and accomplishment of psychological development task are related to psychological ability very much. Psychology On the other hand, elite players had significantly lower score than collegiate players in "Volition for competition" in 5 factors. Also, they had a significantly lower score than collegiate players in "Volition for winning" which is the lower scale of "Volition for competition", and they have lower tendency in "Volition for self-realization". These results are same as Takizawa et al.'s study (2018), which reported that less experienced player had significantly higher score in "Volition for self-realization". Elite players have more opportunity to think about reality based on their life experience because they were matured as a person and they were working in society. Because of it, they are losing of challenging to their own potential, self -affirmation to win as players, and motivation to their future. We assume these are the reason elite athlete had lower score than collegiate player in "Volition for competition", "Volition for winning", and "Volition for self-realization".
The study of Kashizuka et al. (2000), whose participants were handball player, and the study of  whose participants were rugby players reported that experienced players were getting their "Judgment" and "Strategic ability" higher. However, experienced players in this study did not have higher scores related to "Strategic ability" than collegiate players. We have to coach this aspect which did not match to previous studies, to improve ability to compete as one of team tasks in the future.

Summary of findings
Summary of results in this study were the followings: 1) "Judgment" and "Strategic ability" of members of teams and FW were higher than non-members. In addition, "Predictive ability" of FW members was also higher than FW non-members. Also, members of FW and BK had higher "Judgment" and "Strategic ability" than non-members of FW.
2) Elite rugby players had higher "Self-control", and "Ability to relax", "Concentration" and "Mental stability and concentration" than collegiate players. However, collegiate players had higher "Volition for winning" and "Volition for competition" than elite rugby players.

Conclusion
The purpose of this study was to clear their psychological athletic ability by comparison between members and non-members as a team and unit, and also to assess the difference of the psychological ability between elite rugby players and collegiate athletes and collect those data. Based on them, making plans to improve psychological ability for their future and linking how we coach the athletes as well.
Participants in this study were 39 players who belong to elite rugby team and Diagnostic inventory of psychological competitive ability for athletes (DIPCA.3) was used. The results of this study showed the followings: 1) In comparison between members and non-members of elite rugby players,

T. Hatachi et al. Psychology
"Judgment" and "Strategic ability" of members were higher than non-members.
In comparison between members and non-members of FW, "Predictive ability", "Judgment" and "Strategic ability" of members were higher than non-members.
Also, members of FW and BK had higher "Judgment" and "Strategic ability" than non-members of FW.
2) In comparison between elite rugby players and collegiate rugby players, elite rugby players had higher "Self-control", "Ability to relax", "Concentration" and "Mental stability and concentration" than collegiate players. However, collegiate players had higher "Volition for winning" and "Volition for competition" than elite rugby players.
From these results, we concluded that that rugby players need decision making skills in game situations, and psychological skills such as "Judgment" and "Strategic ability" are important in selection criteria of members and coaching guidelines even for the players who belong to companies.
As the previous study of Yonechi et al. (1997) showed that decision making skills in situations are very important, we confirmed that this skill is very important even for elite rugby players when they were selected as members and when coach made a coaching guideline for their team. Also, we confirmed about the relationship between accomplishment of psychological development tasks and improvement of psychological competitive ability like Takizawa et al. showed previously. Based on these results, it will be very helpful as guidelines for coaching rugby and its development of psychological competitive ability. We think that this will link to efficient team development to coach by assessing team characteristics. In this study, we picked up participants from one team and used one psychological assessment. Therefore, we may need to study by using other teams and other psychological assessments to know a tendency in the future.
