In this study, Icelandic youth international soccer players were asked to answer a questionnaire that measured psychological skills, anxiety, and mental toughness. The questionnaire was submitted at two different points of time, once in 2018 and again in 2021. The first aim of the study was to see if players who better utilize psychological skills have lower anxiety and higher mental toughness than those who utilize them less. The second aim was to see if players who start more games have lower anxiety, higher mental toughness, and utilize better psychological skills. The third aim was to investigate if higher skilled players had improved more in psychological skills and mental toughness, and had less performance anxiety compared to those who were not regular starters on their teams. Psychological skills were measured using the Test of Performance Strategies (TOPS) scale, performance anxiety was measured using the Sports Anxiety scale-2 (SAS-2), and mental toughness was measured using The Sport Mental Toughness Questionnaire (SMTQ). The results showed that the better use of psychological skills was negatively correlated with performance anxiety and was positively correlated with mental toughness. Also, the better use of psychological skills in 2018 was negatively correlated with performance anxiety in 2021. No significant correlation was found between better use of psychological skills in 2018 and mental toughness in 2021. The starters were significantly better than non-starters in utilizing psychological skills; relaxation and emotional control during competition in 2018 and automaticity in 2021. Regarding mental toughness, starters scored significantly higher in the control subscale in 2018. Starters had also improved significantly more in the psychological skills; activation and relaxation during competition and negative thinking during practice. No significance was found in the improvement of performance anxiety in 2021 compared to 2018 in either group. In regards to mental toughness, starters significantly improved in the control subscale from 2018 to 2021.
