Positive interpersonal relationships between the coach, the athlete and the parents (C-A-P) in sports are one of the most important factors in relation to athlete’s long-term involvement in sport. In this sense, the evaluation of such relationships is very important in sports context. However, there is a lack of such evaluation instruments related to the C-A-P. It is noteworthy that the only instrument evaluating coach-athlete-parent interpersonal relationships is the English language PNPCAP (Positive Negative Processes Coach Athlete Parent) by Lisinskiene, Lochbaum, May, Huml, (2019). The purpose of this paper is to present the Coach-Athlete-Parent (C-A-P) Positive and Negative Interpersonal Relationship Processes (PNPCAP): Lithuanian version of the questionnaire. It is noteworthy that in order to create a new PNPTST questionnaire, several stages of research were carried out: 1) Two qualitative studies were performed (Lisinskiene, May, Lochbaum, 2019); 2) Two quantitative research studies were done (Lisinskiene, Lochbaum, May, Huml, 2019); 3) Analysis of PNPTST questionnaire, Success perception questionnaire, Sports climate questionnaire, Sports decision-making questionnaires were analysed in order to test PNPCAP validity. Based on the above mentioned research studies, this article presents the Lithuanian version of the PNPTST questionnaire. PNPTST is a suitable brief tool for evaluating coach-athleteparent relationships in both team and individual sports. In the future, it would be useful to translate the PNPTST questionnaire into other foreign languages and use them in other cultures.

Phenomenological analysis revealed the importance of the coaches’ – as a sport educators – sport psychologists – sport professional specialist’s role in encouraging parent–child interaction in youth sport. In order to create a positive motivational environment for young athletes there is a need of a positive training and education strategy used by the coach, the coach’s ability to create parental interest in the child’s sport, to build and maintain positive relationships between sport participants, solve ethical and social problems arising in the sporting environment. The effectiveness of the coach’s influence on parent–child interaction in the sporting environment largely depends on the coach’s basic professional skills and intrapersonal competencies acquired in higher sport education institutions, through growing work experience and various professional development programmes.

Sport plays an important role in the lives of many children. Sport is important not only for the athletes themselves, but also includes other important participants: parents, coaches, referees, teammates. However, in the current period more attention is being paid to children’s sports activities and the influence of parents on the education of young athletes. There is a tendency to note that parental involvement in children’s sports can be diverse. As the researchers highlight, it is important for parents to understand that they should show the young athlete as many as possible ways, to introduce to different sports so that the young athlete later could find himself/ herself, to enjoy sport and to have positive experiences. However, resent research shows that parents’ desire to see their offspring succeeding, and parents often forget what really matters in children’s sport. Therefore, the role of parents in motivating adolescent basketball players in sports is the object of this research. The tasks of the study is to reveal the importance of parents’ (mothers and fathers separately) role in motivating basketball players (15–18 years of age), regarding of the athletes age; and to reveal the importance of parents’ (mothers and fathers separately) role of motivating basketball players regarding athletes experience in their career. The following research methods are used: Analysis of the scientific literature; Quantitative study: Questionnaire; Mathematical statistics methods. Basketball players of two basketball schools (n = 75) participated in the questionnaire survey. The results of this study have demonstrated that mother’s and father’s role is important in both age groups (15–16 years old and 17–18 years old). In autonomy support range (scale) mother’s role is stronger and more important for younger players than in group of 17–18 years old athletes.[...]
