RESUMO

The main objective of this study was to determine whether hope for success mediates the relationship between personality and goal orientation in high performance and recreational athletes. The cross-sectional study included 289 high performance and recreational athletes of various sports (age: M = 20.34, SD = 1.86). To examine personality, we used the Big Five IPIP-BFM-20 questionnaire. To assess hope for success, we used the Hope for Success Questionnaire. The Task and Ego Orientation in Sport Questionnaire (TEOSQ) was employed to examine goal orientation. Hope for success significantly mediates the relationships between conscientiousness, extraversion, emotional stability, intellect, and task goal orientation in sport. Higher levels of these personality traits are related to athletes' higher hope for success, which, in turn, is positively related to their task orientation. Personality traits may underpin the hope for success that develops from childhood. This, in turn, appears to be an important component on which, combined with the positive interaction and support from coaches, a task goal orientation beneficial to sport can be shaped in athletes.

RESUMO

Purpose: An increasing number of studies support the beneficial relationship between physical activity and stress coping in people with multiple sclerosis (MS). However, there has been limited understanding of the variables that may influence the nature of this relationship. Therefore, based on the social-cognitive framework and previous research, we aimed to examine the association between the habitual physical activity of people with MS and their coping effectiveness. Furthermore, we sought to determine the extent to which self-efficacy acts as a mediator in this relationship, considering the level of disability as a moderator variable. Methods: In this cross-sectional study, a total of 351 people with MS participated. The participants were asked to complete several assessment tools, including the Mini-COPE Inventory for Measurement—Coping with Stress, the Generalized Self-Efficacy Scale, and the Godin Leisure-Time Exercise Questionnaire. Additionally, a neurologist assessed the severity of the disease using the Expanded Disability Status Scale. Information on the demographic and clinical characteristics of the participants was collected via a self-report survey. Two moderated mediation analyses were conducted as part of the study. Results: The study findings indicated a positive correlation between engagement in physical activity and self-efficacy among participants with high and medium disability levels. This, in turn, demonstrated a positive association with effective stress-coping strategies and a negative association with ineffective coping methods. In particular, a significant relationship was observed between involvement in physical activity and self-efficacy in participants with high disability, while it was not statistically significant in participants with low disability.(AU)

RESUMO

Achievement goal models have been successfully applied in sport. In recent years, a framework that has emerged in this area is the 3 × 2 approach, being a natural evolution of years of research into the issue of achievement goals. Nevertheless, it is essential to further validate the abovementioned approach and explore its psychosocial context. Hence, the purpose of this study was to validate the latest 3 × 2 achievement goal model among high-performance and recreational athletes using the Polish version of the 3 × 2 Achievement Goal Questionnaire for Sport (3 × 2 AGQ-S), and to determine the relationship between personality traits and achievement goals of athletes. The study included 413 athletes, with M = 20.62 and SD = 2.72. The 3 × 2 AGQ-S was used to assess achievement goals, the Big Five personality traits were assessed using the IPIP-BFM-20 questionnaire. The model of the Polish version of the 3 × 2 AGQ-S achieved a satisfactory fit to the data (CFI = 0.940, TLI = 0.923, RMSEA = 0.086, SRMR = 0.061). Cronbach's alphas for the subscales were: 0.77-0.96. High-performance athletes obtained higher achievement goals in task and self subscales than recreational athletes. Personality traits explained no more than 3% of variance of achievement goals in sport. Research involving the Polish version of the 3 × 2 AGQ-S supports the validity of the 3 × 2 model in sport among high-performance and recreational athletes. Nevertheless, the small relationships between the personality traits and achievement goals prompt searching for other psychosocial determinants of goals in sport.

RESUMO

This study compared external training load (ETL) and its temporal changes across repetitions during a speed endurance production (SEP) training comprised of 1 × 1 short-bout, small-sided games (SSGs) in elite youth soccer players. Twenty U18 players were divided into two groups (SEP1 and SEP2) performing six 30 s and 45 s bouts of SSG (work-to-rest ratio 1:4) on a 10 by 15 m field. ETL was characterized by the total distance covered, Player Load, the total number of accelerations/decelerations, and their relative values (per minute). Significant overall decreases in the ETL parameter values across six repetitions in both SSG groups were observed relative to the measurement in the first set beginning in 3rd (SEP1) or 4th (SEP2) repetitions. Significant greater decreases in Player Load (F(5.90) = 2.99, p < 0.05, η P2 = 0.14), Player Load per minute (F(5,90) = 11.32, p < 0.001, η P2 = 0.39), total distance per minute (F(3.43,61.73) = 7.72, p < 0.001, η P2 = 0.30) and accelerations per minute (F(5,90) = 2.59, p < 0.05, η P2 = 0.13) were observed in the 30-s games than in the 45-s games. In conclusion, the use of SSGs in SEP training is associated with a decrease in the effectiveness of physical work performed across repetitions. In practice, due to the decrease in the measured ETL indicators already in the 3rd or 4th repetition (especially in the SEP1 group), the work-to-rest ratio could be increased from the applied 1:4 to 1:6.

RESUMO

This study aims to assess the validity and reliability of the Polish version of the Sport Anxiety Scale-2, as well as to determine the relationship between anxiety and goal orientation among high-performance and recreational athletes. A total of 519 athletes aged M = 22.83 (SD = 4.92) participated in the study, including 266 males and 253 females. 242 athletes trained professionally and 277 recreationally. The Sport Anxiety Scale-2 (SAS-2) was used to assess anxiety levels, while the Task and Ego Orientation in Sport Questionnaire (TEOSQ) and the Perception of Success Questionnaire (POSQ) enabled to assess athletes' goal orientation. Confirmatory factor analysis showed a good fit of the model to the data for the Polish version of the Sport Anxiety Scale-2 (CFI = 0.945, RMSEA = 0.072). The models obtained during analysis of high-performance and recreational athletes, women and men, also presented a satisfactory fit to the data (CFI 0.932-0.946). The configural, metric, scalar and strict measurement invariances were demonstrated for high-performance and recreational athletes as well as among women and men. High internal consistency coefficients (alpha 0.81-0.91) and a high test-retest reliability indexes were reported (ICC 0.74-0.87). Women presented higher level of competitive anxiety than men. A positive relationship between competitive anxiety and athletes' ego orientation was also presented. This relationship concerned particularly women practicing sport recreationally.

RESUMO

Purpose: Most stroke patients require long-term care of their family members. Excessive care burden entails several negative consequences; therefore, the severity of the burden should be periodically assessed. For this purpose, valid multidimensional measures are needed. Our study, which is a part of a larger research project, aims to translate and evaluate the psychometric properties of the Polish Caregiver Burden Scale (CBS) in relation to construct validity and internal consistency in caregivers of the patients after stroke. Patients and Methods: The sample of this cross-sectional observational study consisted of 366 informal caregivers to consecutive first-ever stroke survivors. The five-factor Polish CBS and the Hospital Anxiety and Depression Scale (HADS) were administered during the home visits at three to six months after patients' hospitalisation. Exploratory (EFA), confirmatory (CFA) factor analyses and a net analysis were performed to investigate the internal structure and a factorial construct validity of the CBS. Correlation analyses between the CBS and the HADS were carried out to examine convergent validity. Cronbach's alpha and item-total correlation were applied to assess internal consistency. Results: Three out of five factors identified by EFA were similar to the original indices of the CBS, while the remaining two deviated from the original structure of the CBS. The CFA five-factor model represented an acceptable fit (confirmatory fit index, CFI = 0.96, root mean square error, RMSEA = 0.04) but only after a modification. All subscale scores of the CBS were positively correlated with the HADS, supporting the convergent validity. Cronbach's alpha coefficients for the overall scale (0.92) and all subscales (0.72-0.87) except one (0.69) and item-total correlation results indicated good internal consistency. Conclusion: The Polish version of the CBS showed acceptable internal consistency and good convergent validity. Factorial validity and structural integrity were partially supported. The interrelationships between the CBS subdomains, their partial mutual contamination, and the scale's non-orthogonal structure should be considered when interpreting the results of further studies using this version of the scale.

RESUMO

Ecosystem-based management requires understanding of food webs. Consequently, assessment of food web status is mandatory according to the European Union's Marine Strategy Framework Directive (MSFD) for EU Member States. However, how to best monitor and assess food webs in practise has proven a challenging question. Here, we review and assess the current status of food web indicators and food web models, and discuss whether the models can help addressing current shortcomings of indicator-based food web assessments, using the Baltic Sea as an example region. We show that although the MSFD food web assessment was designed to use food web indicators alone, they are currently poorly fit for the purpose, because they lack interconnectivity of trophic guilds. We then argue that the multiple food web models published for this region have a high potential to provide additional coherence to the definition of good environmental status, the evaluation of uncertainties, and estimates for unsampled indicator values, but we also identify current limitations that stand in the way of more formal implementation of this approach. We close with a discussion of which current models have the best capacity for this purpose in the Baltic Sea, and of the way forward towards the combination of measurable indicators and modelling approaches in food web assessments.

RESUMO

The appropriate level of coordination motor skills (CMS) in a football player is one of the factors determining the effectiveness of their actions. Adaptability and complex reaction time are of particular importance in models of coordination requirements in football. The lead aim of this study is to determine the relationship between two selected coordination motor skills and the offensive, defensive and comprehensive effectiveness of an individual player's actions. The study was conducted on a group of 91 Polish male football players aged 20 to 31 years, all in the senior age category. The research tools included: a test assessing motor adaptation (research by dribbling the ball with the dominant leg), psychomotor test of complex reaction time (tested with an S-10.2 measuring device) and a test of the effectiveness of an individual player's actions (one-on-one simulation game). The conducted research indicated that adaptability and complex reaction time are both important abilities for success when attacking in an individual game, and in the assessment of a comprehensive index of individual competences in a one-on-one football game. However, the most significant factor influencing the effectiveness of a player's defensive action is solely the complex reaction time.

RESUMO

PURPOSE: The main aim of this study was to analyse the psychometric properties of the Polish version of the Multiple Sclerosis Self-Management-Revised Scale. METHODS: A total of 663 patients with multiple sclerosis were included in this study. The Polish version of the Multiple Sclerosis Self-Management-Revised Scale, The General Self-Efficacy Scale, Multiple Sclerosis Impact Scale-29, and Expanded Disability Status Scale were used. Cronbach's alpha and McDonald's omega coefficients were calculated to assess the Polish version of the scale's reliability. The reliability of the scale's test items was assessed using an information function with the multidimensional graded response model. Confirmatory factor and principal component analyses were conducted. RESULTS: Cronbach's α and McDonald's ω were obtained (α = 0.896, ω = 0.909). Correlations between the scores of the Polish version of the Multiple Sclerosis Self-Management-Revised Scale and the General Self-Efficacy Scale (r = 0.34; p < 0.001) and the neurological assessment of patients by a physician (r = -0.23; p < 0.001) were significant. The original factor structure of the scale was not confirmed (Chi2(242) = 1480; p < .001; CFI = 0.829; TLI = .805; RMSEA = 0.088, 90% CI = [0.084-0.092]; SRMR = 0.079). CONCLUSIONS: Using only the total score of the Multiple Sclerosis Self-Management-Revised Scale is recommended for Polish patients. The scale's factor structure requires further study.Implications for rehabilitationThe Polish version of the Multiple Sclerosis Self-Management-Revised Scale was reliable and valid when used in adult multiple sclerosis patients.At present, we recommend using only the total score of the Multiple Sclerosis Self-Management-Revised Scale. Further research is needed to distinguish the detailed subscales of the Polish version of the tool.The Polish version of the Multiple Sclerosis Self-Management-Revised Scale can be used in clinical practice and for research purposes to assess the general level of self-management in Polish-speaking multiple sclerosis patients in Poland.

RESUMO

Sustainable environmental management needs to consider multiple ecological and societal objectives simultaneously while accounting for the many uncertainties arising from natural variability, insufficient knowledge about the system's behaviour leading to diverging model projections, and changing ecosystem. In this paper we demonstrate how a Bayesian network- based decision support model can be used to summarize a large body of research and model projections about potential management alternatives and climate scenarios for the Baltic Sea. We demonstrate how this type of a model can act as an emulator and ensemble, integrating disciplines such as climatology, biogeochemistry, marine and fisheries ecology as well as economics. Further, Bayesian network models include and present the uncertainty related to the predictions, allowing evaluation of the uncertainties, precautionary management, and the explicit consideration of acceptable risk levels. The Baltic Sea example also shows that the two biogeochemical models frequently used in future projections give considerably different predictions. Further, inclusion of parameter uncertainty of the food web model increased uncertainty in the outcomes and reduced the predicted manageability of the system. The model allows simultaneous evaluation of environmental and economic goals, while illustrating the uncertainty of predictions, providing a more holistic view of the management problem.

RESUMO

BACKGROUND: Identifying the profiles of multiple sclerosis (MS) patients who employ similar patterns of coping may improve the understanding of how coping is associated with psychological adjustment. The purpose of this study was to identify the groups of MS patients using different coping strategies and compare the levels of psychological resources across the groups. METHODS: In this cross-sectional study 382 patients with MS completed a battery of self-report measures that assessed their use of different coping strategies, optimism, self-efficacy, health locus of control (HLC), and perception of disease. The groups with different coping profiles were selected by performing a cluster analysis. RESULTS: Five different coping profiles were highlighted and were defined as follows: "Emotional," "Temperate," "Active," "Passive," and "Problem copers." Significant differences were detected between the groups in the levels of optimism, self-efficacy, HLC, and perception of disease. CONCLUSION: Patients with MS use a varied repertoire of coping strategies, which allowed distinguishing coping profiles. Groups representing particular profiles differ in terms of psychological resources. This study contributed to increasing the interest in investigating coping profiles. Identifying subgroups of individuals based on their coping profiles and recognizing the differences is important for providing psychological support.

RESUMO

INTRODUCTION: In inflammatory bowel diseases (IBD), osteopenia and osteoporosis constitute a significant medical problem. Cytokines, especially IL-17, play an important role in the pathogenesis of IBD and osteoporosis. Vitamin D is a regulator of bone metabolism, and helps maintain immune system homeostasis. MATERIAL AND METHODS: The research sample consisted of 208 persons: 83 patients (age 35 ±11.99 years) with Crohn's disease (CD); 86 patients (age 39.58 ±14.74 years) with ulcerative colitis (UC); and 39 persons (age 30.74 ±8.63 years) in the control group (CG). Clinical data on bone mineral density of the lumbar spine (L2-L4), bone mineral density of the femoral neck (FN), and body mass index (BMI) were collected. 25OHD and IL-17 serum concentrations were also measured. RESULTS: Body mass index (kg/m2) results: in CD, 21.51 ±3.68; in UC, 23.31 ±4.38; and in CG, 24.57 ±3.45 (p < 0.01). Densitometry results for L2-L4 T-score SD: in CD -0.83 ±1.45; in UC -0.47 ±1.15; in CG 0.09 ±0.70. Densitometry results for FN T-score SD: in CD -0.62 ±1.26; in UC -0.29±1.17; in CG 0.41 ±1.03 25OHD (ng/ml) serum concentrations: in CD, 21.33±12.50; in UC, 22.04±9.56; in CG, 21.56±9.11 (ns). IL-17 (pg/ml) serum concentrations: in CD, 8.55±10.99; in UC, 11.67±12.97; in CG, 5.16±9.11 (ns). CONCLUSIONS: Inflammatory bowel diseases patients and persons from the CG did not differ in vitamin D or IL-17 levels. Patients with a mild course of the disease had a higher vitamin D concentration and bone mineral density. In UC, higher vitamin D concentrations were associated with lower IL-17 concentrations. The IBD patients with a severe course of the disease had a lower body mass than those in the CG and the patients with a mild course of the disease.

RESUMO

An effective visual perception strategy helps a fencer quickly react to an opponent's actions. This study aimed to examine and compare visual perception strategies used by high-performance foil fencers (experts) and beginners. In an eye tracking experiment, we analysed to which areas beginning and expert fencers paid attention during duels. Novices paid attention to all examined areas of interest comprising the guard, foil (blade and tip), armed hand, lower torso, and upper torso of their opponents. Experts, however, paid significantly less attention to the foil, picking up information from other areas, mainly the upper torso and the armed hand. These results indicate that expert fencers indeed engage different visual perception strategies than beginners. The present findings highlight the fact that beginner fencers should be taught already in the early stages of their careers how to pick up information from various body areas of their opponents.

RESUMO

Motivational factors are among the most important determinants of undertaking and participating in physical activity. An adequate measurement of motivation and the assessment of its initial characteristics form the basis for possible further practical interventions of a compensatory or promotional nature. Considering the above, the main aim of this study was to assess the psychometric properties of the Polish version of the Goal Orientation in Exercise Measure (GOEM), and to determine the association between the task and the ego orientations and selected components of physical activity, i.e., frequency of undertaking, declared time per session and time spent on physical activity. In addition to the typical indices of psychometric assessment, an analysis of the reliability of test items by applying the item response theory (IRT) model was also presented. The study included 318 individuals (173 females, 145 males), aged 21 years on average, undertaking recreational physical activity. The GOEM scale by Petherick and Markland (2008) was used. The model of the Polish version of the GOEM scale fitted the empirical data well (CFI = 0.955). Satisfactory reliability indices were also obtained (task subscale: alpha = 0.83, omega = 0.83; ego subscale: alpha = 0.86, omega = 0.86). Reliability, as assessed by the test-retest method, was ICC = 0.80 for the task subscale and ICC = 0.87 for the ego subscale. The IRT analysis showed that the ego subscale was more precise in the middle level of the trait, while the task subscale provided more information in the low and middle level of the trait and relatively little information in the high level of the trait. The positive associations of the task subscale with the frequency of physical activity and the time spent in a single exercise session were also noted.

RESUMO

Low level of self-management in people with multiple sclerosis (MS) is considered to be a predominant factor that leads to poor rehabilitation efficacy. Studies focusing on the relationship between self-management and psychological variables that can be modified could contribute to expanding the knowledge needed to propose interventional programs aiming at patient activation. This study aimed to analyze whether coping strategies play a mediating role in the association between the perceived impact of MS and level of self-management in people with MS. The cross-sectional study included 382 people with MS. The participants completed the Multiple Sclerosis Self-Management Scale-Revised, Multiple Sclerosis Impact Scale-29, and Coping Inventory for Stressful Situations. The study hypothesis was evaluated using mediation analysis. The STROBE checklist specifically prepared for cross-sectional research was applied in this study for reporting. Results indicate that the emotion- and problem-focused strategies of coping can be treated as mediating the association between the MS impact and level of self-management in people with MS. A negative relationship was found between the perceived MS impact and problem-oriented coping, while a positive relationship was found between problem-oriented coping and self-management. Furthermore, a positive relationship was found between the MS impact and emotion-oriented coping, while a negative relationship was found between emotion-oriented coping and self-management. The indirect role of avoidance-oriented coping was not significant. Our study confirms the role played by coping strategies in individuals' self-management. In MS, self-management determined by perceived MS impact can be controlled by decreasing emotional-coping while increasing problem-coping strategies. Our study imparts new knowledge regarding the potential interventions for improving the level of self-management in people with MS. It indicates that recognition of individuals' illness perceptions as well as maladaptive coping strategies can help health professionals identify those who might be having lower level of self-management.

RESUMO

In the etiology of inflammatory bowel disease (IBD) and osteoporosis, the connecting element is the involvement of environmental and genetic factors. Vitamin D receptor (VDR) gene polymorphisms may be associated with the pathogenesis of IBD and bone mineral density (BMD). The study aimed to analyze the relationship between ApaI and FokI polymorphisms of the VDR gene, serum vitamin D concentration, and BMD in patients with IBD. The studied group consisted of 172 patients (85 with Crohn's disease [CD], 87 with ulcerative colitis [UC], and 39 healthy subjects - control group [CG]) were examined. Lumbar spine densitometry (L1-L4) and the femoral neck (FN) measurements were performed using dual-energy X-ray absorptiometry (DXA). Serum concentrations of 25-hydroxyvitamin D were determined using electrochemiluminescence binding assay (ECLIA). Polymorphisms were determined with polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). . We found no statistically significant differences in vitamin D concentration between the 3 studied groups. CD patients who were FF homozygotes had significantly lower FN BMD than FF homozygous from CG (p-value < 0.05). CD patients who were Aa heterozygotes had significantly lower lumbar spine (L2-L4) BMD than Aa heterozygotes from CG (p-value < 0.05). Among patients with the same polymorphic variants, but belonging to different studied groups, statistically significant differences in bone mineral density in the lumbar spine and the closer end of the femoral neck were observed. We consider that it is the disease entity, not the polymorphism variant, may have a decisive impact on BMD.

RESUMO

The main aim of the study is a comprehensive assessment of psychometric properties of the Polish version of Perception of Success Questionnaire (POSQ) in sport. Apart from standard psychometric evaluation, the paper presents an analysis of item reliability through the use of Item Response Theory, as well as the analysis of relationships between sport type, level of participation, gender and goal orientation level. The study covered 412 people aged M = 23.46 (SD = 5.40). The Perception of Success Questionnaire (POSQ), the Task and Ego Orientation in Sport Questionnaire (TEOSQ) and the Sport Motivation Scale (SMS-28) were used. High reliability of POSQ ego subscale (α = 0.89, ω = 0.89) and POSQ task subscale (α = 0.90, ω = 0.91) were noted. The test-retest correlations at the two-week interval were ICC = 0.91 for ego subscale, and ICC = 0.71 for task subscale, respectively. Confirmatory factor analysis showed a relatively good fit of the two-factor model to the data (CFI = 0.94). Relationships between the goal orientation measured by the POSQ questionnaire and motivational traits measured by TEOSQ and SMS-28 were obtained. It was also shown that high-performance athletes had higher scores on the ego factor than recreational athletes. Moreover, men had higher scores on the ego factor than women. The Perception of Success Questionnaire (Polish version) is characterized by satisfactory psychometric properties and can be used for scientific research and diagnosis.

RESUMO

Objectives: Health-related fitness is a good predictor of health status of children and adults. Less is known about relationships of health-related fitness components between parents and children. Methods: Our study involved 58 children (30 girls and 28 boys, mean age = 7.97) and 58 parents (33 mothers, mean age = 39.32, and 25 fathers, mean age = 38.73) who were voluntarily enrolled in the program in 3 selected primary schools in the city of Poznan, Poland. Physical fitness was measured using the Eurofit test battery. Assessment of body composition was performed by measuring the bioimpedance. Results: Positive relationships were found among the levels of strength of abdominal muscle, flexibility of parents, and the slenderness of children. Slimmer parents also had more physically active children. Body composition parameters also were related to physical activity. More relationships were found between children and parents of the same sex. Conclusion: Data support the hypothesis that health-related risk factors are linked between parents and children and that sex plays an important role in these relationships. Our findings reinforce the need to develop health promotion programs that include children and their parents.

RESUMO

Left handers have long held the edge over right handers in one-on-one interactive combat sports. Particularly in fencing, top rankings show a relatively strong overrepresentation of left handers over right handers. Whether this can be attributed to perceptual strategies used by fencers in their bouts remains to be established. This study aims to verify whether right-handed fencers assess their opponents' behaviour based on different perceptual strategies when fencing a left vs. right hander. Twelve top-level (i.e., Olympic fencers, Junior World Team Fencing Champions, and top Polish senior foil fencers) right-handed female foil fencers (aged 16-30 years) took part in the study. They performed a total of 40 actions: 10 repetitions of offensive actions (attack) and 10 repetitions of defensive actions (defence), each type of action performed under 2 conditions (right- vs. left-handed opponent). While the participants were fencing, their eye movements were being recorded with a remote eye-tracker (SMI ETG 2.0). Both in their offensive and defensive actions, the fencers produced more fixations to the armed hand and spent more time observing the armed hand in duels with a left-handed (vs. right-handed) opponent. In defence, it was also the guard that attracted more fixations and gained a longer observation time in bouts with a left hander. In duels with a right-handed opponent, a higher number of fixations in attack and in defence, and longer observation times in defence were found for the upper torso. The results may point to different perceptual strategies employed in bouts with left- vs. right-handed individuals. The findings from this study may help to promote the implementation of specialized perceptual training programmes in foil fencing.

RESUMO

The main aim of the study was to assess the psychometric properties of the Polish version of the task and ego orientation in sport questionnaire (TEOSQ). The study covered 651 athletes aged 19.2 years, SD (Standard deviation) = 2.21. The task and ego orientation in sport questionnaire (TEOSQ) and sport motivation scale (SMS-28) were used. Cronbach's Alpha for the ego subscale was 0.84, and for the task subscale 0.81 (McDonald's omega was 0.84, 0.82 respectively). The reliability of the test-retest with two weeks interval was ICC (Intraclass correlation coefficient) = 0.86 for ego and ICC = 0.86 for task. Initially, the two-factor model was not fully fitted (CFI (Comparative fit index) = 0.84), however the model with correlated errors for selected test items was well fitted to data (CFI = 0.95). Statistically significant, positive correlations between the task orientation and the intrinsic motivation components were obtained. Additionally, individual athletes had higher scores on the ego factor and lower scores on the task factor than the team athletes. These effects were moderated by the level of participation and occurred among high-performance athletes. Due to satisfactory reliability and validity indicators the Polish version of the task and ego orientation in sport questionnaire (TEOSQ) can be used both for scientific research and in the individual diagnostics of athletes.
