Introduction
Consequences of disability include disorders of the functions or structures of the body, as well as significant problems with the healthy functioning of the disabled person as a member of society [1]. One of the most important areas in exercise with disabled people is to provide the conditions for their growth and socialization, neutralize negative emotional changes and prepare the person for physical and mental adaptation to new living conditions [2]. Competitive sport is considered a way to improve military veterans due to its physiological, psychological, and social benefits [3]. Exercise has become an important way for recovery after injury, adaptation, integration, and social coping of people with disabilities. The participation of people with disabilities in sports activities has important social consequences for an individual and the whole society [4].
Disabled athletes of different ethnicities with different cultures prepare for global events at national camps. On the other hand, as the country’s representatives, these people are connected with the different cultures of other countries. Differences in language, ethnicity, politics and many other characteristics can emerge as a potential source of conflict, which, if misunderstood, will make the problems for communication [5]. The effective interpersonal factors on the conflictions are the quality of relationships (including mutual respect and trust, commitment and joint orientation), communication (the process of developing and maintaining relationships and familiarity with the other person's needs and expectations for effective interaction), group unity (accepting the individual role in the team and understanding other team members, relationships and cooperation between the coach and the athlete) [6]. Training programs and competitions, expectations, values or interpersonal discrimination, and team selection processes may lead to conflicts between athletes and coaches or even the sports organization. The mentioned cases become more widespread after significant events inside or outside the country [7]. Conflict is a danger to any relationship if it is not resolved constructively. The ability to resolve conflict has been defined as the skill of effectively resolving a conflict by choosing the most appropriate strategy in each situation [8]. Therefore, relationship partners may decide to avoid situations leading to conflict, including public relations strategies and behaviors specifically focused on potential differences [9].
One of the psychological characteristics that help people to adapt to the culture of others is cultural intelligence. Cultural intelligence allows one to try other cultures effectively and interact with people from different cultures [10]. Individuals adjust their concepts and mental images based on real experiences that did not meet their expectations [11]. Cultural intelligence is the ability to learn new patterns in cultural interactions, provide correct behavioral responses to these patterns, and understand the appearance and inside of people intellectually and practically. It also provides a framework for understanding and investing in differences rather than tolerating or ignoring them. The level of cultural intelligence, in addition to affecting the efficiency of athletes of national teams (futsal, volleyball, basketball, and handball), the cohesion of sports teams, improvement of technical capabilities and performance of athletes [13-15], is effective in resolving the conflict between athletes and their coaches and approaches to prevent and manage interpersonal conflict [6]. It is well known that psychological skills have a significant impact on athletes' function and individual development. Professional athletes have excellent physical skills, but they must also have high psychological skills to control emotions by coping with stress and pressure, intense concentration, and setting challenging but realistic goals [16]. High levels of sports competition create high-pressure conditions for veteran and disabled athletes [17]. Sports success is an active learning process achieved through purposeful exercise and the necessary skills to achieve high sports performance and success [18]. A clear understanding of the nuances in the development of athletes with disabilities is important to create appropriate programs and strategies [19].
Factors influencing the development of athletes with disabilities are relatively less known than healthy athletes; therefore, special sports training programs are essential for the successful performance of athletes with disabilities. This study aimed to investigate the role of cultural intelligence and the ability to resolve conflict as psychological characteristics on the sports success of Iranian veterans and disabled athletes.
Instrument and Methods
The present descriptive-correlational research is applied research that was conducted by field method. This study was conducted on all disabled Iranian athletes and veterans participating in official competitions (n=389). Sports included wheelchair basketball, sitting volleyball, football, weightlifting, archery, athletics (weightlifting, javelin throw, discus throw, jumping), tennis, and boccia. The variables of the study were assessed using the cultural intelligence questionnaire of Ang & Earley with 20 items in four dimensions of metacognitive, cognitive, motivational, and behavioral (7-point Likert scale) [20], the Vickers & Fisher Conflict Resolve Questionnaire consists of 40 items in 10 subscales including conflict as a natural thing, space, and situation, transparency of receipts and impressions, paying attention to needs instead of wants, creating a positive collaborative relationship, focus on the future by learning from the past, provide options for mutual benefit, expand and provide achievable tasks and goal setting step by step, establish mutual benefit agreements excessive consideration (on a 5-point Likert scale) [21]. Vaez-Mousavi’s Sports Success Questionnaire, including 29 questions, was used in 6 subscales of Fluent performance, attention, technique, error sensitivity, commitment and progress (on a 6-point Likert scale) [22].
After obtaining ethical permission from the National Committee for Ethics in Biomedical Research and other necessary licenses, the researcher personally attended the training site of the sports teams and asked the subjects to fill out the questionnaires after giving full explanations about the research and receiving informed consent.
To test the hypotheses based on the conceptual model, multivariate regression analysis and structural equation modeling were used using SPSS 23 and AMOS 22 software. Fit indices based on three absolute, adaptive, and economical types were used to evaluate the model’s fit. The bootstrapping method was used to examine the parameters more accurately; Bootstrapping is a statistical method that resamples a dataset many times. A total distribution of samples can be achieved using the results of all sampling times. This distribution provides the basis for the estimates and the standard error estimation for the various parameters. However, the standard error is expected to be more accurate than the sampling load. The main sample from which the sub-samples are taken is a representative sample of the community. In bootstrapping, the distribution of experimental samples is obtained by multiple sub-sampling (200 times or more) instead of estimating the standard error based on one sample [23].
Findings
The frequency of the females was 43.5%, and males were 56.5%. The average age of the subjects was 26.62±7.22 years. Sports history of 16, 56.6, 12.4, and 5.9% of the subjects were less than 5, 5-10, 10-15, and more than 15 years, respectively. The highest level of competition the subjects have participated in were 5.7, 33.5, 17.1, and 11.4% of provincial, national, Asian, global, and Paralympic competitions, respectively. The frequency of winning bronze, silver, and gold medals was 15.3, 18.2, and 66.5%, respectively.
The results showed a significant correlation between most research variables (p<0.05; Table 1).
