positively correlated (Bell & Poul, 2009). The world
of sport recognizes the importance that confidence
has on success (Cox, 2007).
The sources of sport confidence identified by the
athletes were categorised into nine global
dimensions representing preparation, performance
accomplishments, coaching, social support, innate
factors, experience, competitive advantage, trust and
self-awareness. The role of the coach in the form of
social support for the athlete is very important, in the
environment of swimming sports the reality on the
field of the coach becomes a central figure. One of
the functions of sport psychology over 80 years ago
was that experienced and successful coaches and
athletes be systematically studied for the purposes of
identifying the psychological principles they
employ, so that these principles can then be
disseminated to inexperienced and less successful
coaches and athletes. Few studies have explored
sport confidence in World Class sport performers;
although there is evidence to suggest that these
athletes derive confidence from mental and physical
training and performance accomplishments (Cox,
2007)
(Landy & Conte, 2007).
2 METHODS
The subject of this research is the swimming athletes
in Yogyakarta Special Region province, which
joined the Swimming Fun Championship 2019. The
total population of the swimming athlete is 78
people consisting of 33 males and 45 females from
12 swimming clubs. This present study employed
purposive sampling technique. The samples in this
study were 30 athletes consisting of athletes in the
age of 10 to 12 years old (FINA, 2017). Before
conducting further research, the participants were
first required to fill out a letter of willingness to be
involved in this research.
In this study, the data were collected through
instruments investigating athlete’s performance at
Swimming Fun Championship 2019, which then
included in data documentation by the researchers.
In addition, this research instrument also used both a
self-confidence scale and social support model for
collecting data. The questionnaire consists of 45
items divided into 21 items measuring social support
and 24 item concerning self-confidence. The
statement in the questionnaire include four choices
of answers, namely VA (very appropriate), A
(appropriate), NA (not appropriate), and VNA (very
inappropriate). The scoring system for each
statement is different. A favourable statement, the
answer score will move from number 4 for VA, 3 for
a, 2 for NA san 1 for VNA, whereas in the
unfavourable statement, the answer score will move
from number 1 for VA, 2 for A 3 for NA and 4 for
VNA.
All the statements in the questionnaire refer to
the variables in this research that is self-confidence
and social support model (Landy & Conte, 2007).
The aspects of social support refer to the theory put
forward by Landy and Conte (2007) including
appreciation, informative, emotional and
instrumental. Social support in this study is
expressed by the scale of social support. The higher
the score obtained by the subject, the higher the
social support. On the contrary, the lower the score
obtained by the subject, the lower the social support.
In addition, the aspects of self-confidence refer to
the theory put forward by Lauster (1992) which
includes optimism, confidence in one’s ability,
objective, consequence, rationality and reality. Self-
confidence in this study is expressed by the scale of
self-confidence. The higher the score obtained by
the subject, the higher the self-confidence. In
contrast, the lower the score obtained by the subject,
the lower the self-confidence. Meanwhile the
performance athlete used the result on 50 m and 100
m freestyle at swimming fun championship 2019.
After all the data were collected, they were
processed with descriptive statistical techniques
using SPSS 16 for windows program. Meanwhile for
the data analysis by using PLS (Partial Least Square)
in which the processing was done by Smart PLS 3.0
program to test suitability of measurement model
with existing data in field.
3 RESULT AND DISCUSSION
The data collected for the study were analysed using
SPSS 16 for Windows to get a general description of
the respondents’ data. Furthermore, to test the
suitability of measurement model with existing data
field will use SmartPLS program. The result of the
data is presented below.
