The main scope of the research was to identify and explain the differences in situational efficiency and individual psychological characteristics of futsal players with different competitive performance. The respondent sample represented a total of 127 players and goalkeepers from all 10 clubs of the First Minifootball Division in Croatia in the first part of the 2020/2021 season, observed in all 45 matches, 9 rounds of the mid-season. Sample for variable in this research is divided in 3 groups: competitive performance, situational efficiency and psychological characteristics. Competitive performance is defined with reference to the quality of the player within the team and the club rank. Situational efficiency is described by the ratio of the sum of the selected indicators and in the period of 600 seconds of every observed player. It is defined by the variables that were written down during the matches as the performance indicators of the futsal players and goalkeepers. Futsal players are evaluated by variables in the phase of defense (overall/successful/unsuccessful: knocking the ball away, fumble recovery and intercepting) and in the phase of offense (overall/successful/unsuccessful: dribbling and feinting, ball receiving, active and passive ball passing and shots on target). Futsal goalkeepers are evaluated by the defense variables (overall/successful/unsuccessful saves: kicks within penalty area, kicks outside the penalty area and individual actions) and pass variables (overall/successful/unsuccessful: active and passive ball passing (by hand); overall/successful/unsuccessful: active and passive ball passing (by foot)). Psychological characteristics were assessed by means of questionnaires Competitive State Anxiety Inventory – 2, CSAI-2 and Athletic Coping Skills Inventory – 28, ACSI-28. Data processing methods include the calculation of parameters of reliability and sensibility. One-way ANOVA was used in order to identify statistically significant differences between the groups. Bonferroni post hoc was used for identification of statistical significance of the main effect. Multiple regression analysis with the use of cross-validation of generated regression model was used in order to determine a statistically significant correlation. Metric characteristics of all used variables were determined by applied analysis to evaluate situational efficiency and psychological characteristics. The correlation coefficient values (r) between test-retest method in establishing the reliability on the applied variables vary from 0,94 – 1,00 and they are all statistically significant. KS test values do not exceed the limit values, asymmetry measures, and the roundness of distribution does not deviate from the normal distribution. Used tests meet the reliability, homogeneity and sensibility criteria in assessing situational efficiency. In Athletic Coping Skills Inventory questionnaire and Competitive State Anxiety Inventory the reliability of scales of internal consistency (Cronbach alpha) are ranked between 0,61 – 0,88. Because this research is at an early stage of determining psychological characteristics of futsal players, scales with internal consistency 0,60 – 0,69 can be considered as low but conditionally satisfactory reliability. Differences between the groups of futsal players and futsal goalkeepers were analyzed in the space of the situational efficiency. The most successful futsal players in the most variables have higher average values. By analyzing the situational efficiency of futsal players significant differences were obtained in 13 out of 18 observed variables in the phase of offense and a significant difference in 1 out of 9 observed variables in the phase of defense. The biggest differences between the groups of competitive performance were determined in the phase of offense in the ball receiving and passing, especially with the purpose of continued ball possession and/or preparing the team for the offense in order to activate the game and/or achieving positive transition and/or creating a favorable opportunity to score (assistance, pre-assistance). Competitively more successful futsal players are significantly better than competitively less successful futsal players in the situational efficiency in the phase of offense, while in the phase of offense there is no significant difference, besides in unsuccessful fumbles. Significant differences in the space of the situational efficiency futsal goalkeepers were obtained in 3 out of 24 observed variables. Significant differences in 1 out of 7 observed variables were obtained by analyzing variance in the space of coping style for sport, while in the space of competitive anxiety there were in 1 out of 3 observed variables. In psychological coping skills that is Peaking under Pressure and in psychological skills of a state of competitive anxiety Cognitive Anxiety. The most successful futsal contestants significantly differ from the least successful futsal contestants in those differences. By means of discriminant analysis in the space of coping style for sport it was determined that more successful futsal contestants significantly differ from those that are less successful, while in the space of psychological characteristics there were no significant differences. In psychological characteristics of coping style for sport the scales Peaking under Pressure and the State of Anxiety contribute the most to differentiation of 4 groups of futsal contestants with different indices of individual competitive performance. The correlation of situational efficiency of futsal players and the final outcome of the matches was determined by means of multiple regression analysis. In the results of the criterion variable prediction of the goal difference the club’s performance in the variables ball pass – active, successful and ball fumble – successful significantly contributes to the prognosis of success. No correlation of a set of predictor variables has been determined with the futsal goalkeepers, in which the performance was observed with the final outcome of the matches, goal difference. In the space of the psychological characteristics the significant correlation of futsal contestants and the final outcome of the matches can be seen only in the scale Athletic Coping Skills Inventory, Peaking under Pressure.
