Psychometric evaluation of the Chinese version of the Multidimensional Competitive Orientation Inventory

This study examined the psychometric properties of the Chinese version of the Multidimensional Competitive Orientation Inventory (Ch-MCOI) in adults from Mainland China. A total of 1121 participants (50.6% male; M = 28.86, SD = 8.70) were recruited for this study. All participants completed the Chinese versions of the MCOI, the Connor-Davidson Resilience Scale (CD-RISC), the Warwick-Edinburgh Mental Well-being Scale (WEMWBS), the Almost Perfect Scale-Revised (APS), the Frost Multidimensional Perfectionism Scale (MPS-f), and the Competition Attitude Scale (Ch-CAS). A subsample of 239 participants (50.6% male; M = 32.04, SD = 8.13) completed the Ch-MCOI again after a two-week interval to assess test–retest reliability. Exploratory Structural Equation Modeling (ESEM) yielded a four-factor structure (hyper-competitive orientation, self-developmental competitive orientation, anxiety-driven competition avoidance, and lack of interest toward competition), which was further validated by confirmatory factor analyses with a satisfactory fit. Furthermore, test–retest reliability, internal consistency, and convergent and concurrent validity were also acceptable. Our findings suggest that the Ch-MCOI could be a reliable and valid instrument for assessing the adaptive and maladaptive facets of competitive orientations in the Chinese-speaking population.

through system control and manual checking.In the system control, the WJX platform excluded respondents with the same IP, the same device, or an incorrect answer to lie questions (e.g., What is the capital of China?).In manual checking, WJX staff excluded respondents with an abnormal completion time (i.e., extremely long or short), inconsistent responses (e.g., conflicting responses to two items with the same content), or inattentive responses (e.g.all responses identical on a measurement).Thus, our final sample size following data quality control was 1121 participants.Moreover, a sample of 239 participants (50.6% male, M = 32.04,SD = 8.13) completed the Ch-MCOI again after a two-week interval to assess test-retest reliability.All participants gave written informed consent prior to participation.This study was approved by the Ethical Review Board of the University of Nanjing.This study has been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments.

Measures The Chinese version of the Multidimensional Competitive Orientation Inventory (Ch-MCOI)
The MCOI is a 12-item self-report instrument that measures four facets of competitive orientation.Each item was rated on a Likert-6 point scale from 1 (not true to me at all) to 6 (completely true to me) 27 .It consists of the following four subscales: Hyper-Competitive Orientation, Self-Developmental Competitive Orientation, Anxiety-Driven Competition Avoidance, and Lack of Interest in Competition.As suggested by Ember and Ember 26 and Beaton et al. 28 , a two-way translation was performed independently.Specifically, two bilingual translators in China first translated the items of the MCOI into Chinese.Then, two bilingual translators in the U.S.A. back-translated their work.The original and back-translated versions were compared and discussed by the authors and translators.The purpose of this work was to minimize discrepancies between the translated instrument and the original instrument.

The Chinese version of the Connor-Davidson Resilience Scale (Ch-CD-RISC)
The Chinese version of the CD-RISC is a 10-item self-report instrument that assesses the level of individual psychological resilience 29 .Each item was rated on a Likert-5 point scale from 0 (not true at all) to 4 (true nearly all the time).The higher the score, the higher the perceived resilience level; the lower the score, the lower the perceived resilience level.Cronbach's α was 0.91 in this study, demonstrating adequate reliability.

The Chinese version of the Warwick-Edinburgh Mental Well-being Scale (Ch-WEMWBS)
The Chinese version of the WEMWBS is a 14-item self-report instrument that assesses the quality of life in terms of mental and social well-being 30 .Each item is rated on a Likert-5 point scale from 1 (none of the time) to 5 (all of the time).The higher the score, the higher the perceived level of quality of life; the lower the score, the lower the perceived level of quality of life.Cronbach's α was 0.94 in this study, demonstrating adequate reliability.

The Chinese version of the Almost Perfect Scale-Revise (Ch-APS-Revised)
The Chinese version of the APS-Revised is used to assess positive and negative aspects of perfectionism and refers to another 22-item self-report instrument 31 .Each item is rated on a Likert-7 point scale from 1 (strongly disagree) to 7 (strongly agree).It contains the following three subscales: high standards, order, and discrepancy.Cronbach's α for the total scale was 0.91 in this study, demonstrating adequate reliability.

The Chinese version of the Frost Multidimensional Perfectionism Scale (Ch-MPS-f)
Multidimensional perfectionism was measured using the Chinese version of the MPS-f 32 , which comprises 27 items, rated on a Likert-5 point scale ranging from 1 (Strongly disagree) to 5 (Strongly agree).It consists of the following 5 subscales: Concern over Mistakes, Doubt about Action, Parental Expectation, Organization, and Personal Standard.Cronbach's α for the total scale was 0.89 in this study, demonstrating adequate reliability.

The Chinese version of the Competition Attitude Scale (Ch-CAS)
The Chinese version of the Competition Attitude Scale (Ch-CAS) includes 27 items, rated on a Likert-5 point scale ranging from 1 (Strongly disagree) to 5 (Strongly agree) 21 .It consists of a benign competitive attitude subscale emphasizing individuals' attitude towards competition in terms of individuals' own development and ability enhancement and a negative competitive attitude subscale emphasizing individuals' attitude towards competition in terms of competing and winning at all costs as a means of maintaining or enhancing one's self-worth.This scale showed a Cronbach's alpha of 0.92, indicating high reliability.

Statistical analysis
Statistical analysis was involved in the following steps: (1) descriptive statistics calculations, (2) item analysis, (3) Exploratory Structural Equation Modeling (ESEM) and confirmatory factor analysis (CFA), and (4) assessment of reliability and, convergent and concurrent validity.
Specifically, calculations were made to identify descriptive statistics for the separate items of the Ch-MCOI for all the valid data including means, standard deviations, skewness, and kurtosis.An acceptable range indicating the normality of the items (skewness within ± 2.00 and kurtosis within ± 7.00) was adopted 33,34 .The data was split into two subsamples via odd and even numbers, with one serving as an exploratory subsample (Subsample 1, n = 560) and the other serving as a validation subsample (Subsample 2, n = 561).The item analysis of the Ch-MCOI was performed on Subsample 1 and determined the validity of each item using two methods.As the original English version of the MCOI is a multidimensional scale, the first method involved calculating the item-total correlation (ITC) between the score of each item of a factor of the Ch-MCOI and the total score www.nature.com/scientificreports/for that factor.The same procedure for performing item analysis as that described in the English version of the MCOI 27 was used for this.The second method involved the use of the critical ratio (CR) to determine the level of item discrimination for each factor of the Ch-MCOI.Then, to reveal the factor structures of the Ch-MCOI, we employed the same method as that described in the English version of the MCOI 27 .We conducted Exploratory Structural Equation Modeling (ESEM) on Subsample 1 and Subsample 2, to examine and validate the proposed four-factor structure of all 12 items.ESEM is a method of combining Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) 35,36 which enables the explicit description of item-level cross-loadings and also makes it feasible to fix these cross-loadings to zero 37 .The following seven fit indices were reviewed to assess the goodness-of-fit of the proposed four-factor structure of the Ch-MCOI, including the Chi-square statistic, root mean square error of approximation (RMSEA), standardized root mean square residual (SRMR), Bentler-Bonett normed fit index (NFI), incremental fit index (IFI), comparative fit index (CFI), and the Tucker-Lewis Index (TLI).Based on the recommendations by previous research 38,39 , 0.90 is thought to indicate a good fit for the NFI, IFI, CFI, and TLI indices.For the RMSEA and SRMR, values below 0.05 indicate a good fit, and values between 0.05 and 0.08 indicate an acceptable fit.In addition, reliability was assessed in terms of internal consistency reliability and test-retest reliability.Both Cronbach's alpha (α) and composite reliability (CR) were used to measure the internal consistency.Given that the original version of the MCOI is a multidimensional scale, Cronbach's alpha (α) and composite reliability (CR) were calculated for each factor of the Ch-MCOI, with values of 0.70 or higher indicating good reliability 40,41 .The 2-week test-retest reliability was also assessed for each factor of the Ch-MCOI via intra-class correlations (ICC).Meanwhile, both the convergent and concurrent validity of the Ch-MCOI were assessed.The average variance extracted (AVE) was estimated for each factor of the Ch-MCOI, with values of 0.50 or higher confirming the convergent validity.We followed the same procedure for assessing the concurrent validity of the English version of the MCOI 27 .Specifically, the concurrent validity of the Ch-MCOI was estimated through partial correlations to examine the relationship between the scores of each facet of the Ch-MCOI and the scores of the Ch-CD-RISC, the Ch-WEMWBS, the Ch-APS-Revised, the Ch-MPS-f, and Ch-CAS.Finally, given that gender differences in competition have been reported 26,42,43 , we further explored whether there is a potential gender effect on the Ch-MCOI scores using an independent sample t-test.Before doing this, we evaluated the invariance across gender groups for equality of the overall factor structure (configural invariance), equality of item factor loadings (metric invariance), and equality of item intercepts (scalar invariance) 44,45 .All data analyses were performed using IBM SPSS Statistics 25.ESEM was conducted with Mplus 7.4.A p-value of < 0.05 was considered to indicate a statistically significant finding.

Descriptive statistics
The descriptive statistics for each item are provided in Table 1, including means, standard deviations, skewness, and kurtosis.All skewness and kurtosis statistics were within the acceptable range (skewness within ± 2.00 and kurtosis within ± 7.00), which indicates that item scores followed an approximately normal distribution.

Item analysis
Our item-total correlation (ITC) test showed that the correlation coefficient (r) was between 0.77 and 0.91, reaching a significant level (ps < 0.001) (Table 2).This indicates that all 12 items had good psychometric properties.Meanwhile, the critical ratio (CR) method was also employed to determine the level of item discrimination for each factor of the Ch-MCOI.This method typically sets 27% of each factor's total score as the boundary point.The factors with a score in the top 27% were classified as a high-score group (n = 151), and those with a score in the bottom 27% were classified as a low-score group (n = 151).Then, an independent sample t-test was adopted to test whether each item could achieve a significant level.Our results revealed that Ch-MCOI CRs were between 18.44 and 33.46, reaching a significant level (ps < 0.001).This suggests that Ch-MCOI item discrimination is high.3).Moreover, there was a significant correlation across all four factors (r = -0.17~ 0.48, p < 0.01), consistent with the original research 27 .Given that this result supports the proposed four-factor structure of the English version of the MCOI 27 , we used the same terms to name these four factors: "Hyper-Competitive Orientation (HCO)", "Self-Developmental Competitive Orientation (SDCO)", "Anxiety-Driven Competition Avoidance (ADCA)", and "Lack of Interest in Competition (LIC)".Subsequently, to verify the factor structure identified, we carried out a confirmatory factor analysis (CFA) on Subsample 2. Our results showed that the model fit indices were acceptable (χ 2 = 184.05,df = 48, CFI = 0.95, TLI = 0.93, SRMR = 0.05, RMSEA = 0.07, NFI = 0.93, IFI = 0.95) (Table 4, Fig. 1).This solution confirmed that the four-factor structure of the Ch-MCOI is adequate.

Reliability
To assess the reliability of the CH-MCOI, Cronbach's α and composite reliability (CR) were calculated for each factor of the Ch-MCOI.The Cronbach's α for each of the four factors was acceptable, between 0.75 and 0.85 (Table 5).Similarly, the CR for each of the four factors was also acceptable, between 0.81 to 0.90 (Table 5).These results demonstrate the satisfactory internal consistency of the Ch-MCOI.The ICC was used to assess the 2-week test-retest reliability.The ICC coefficient for each of the four factors was between 0.67 and 0.73 ( p < 0.001), which was significant (ps < 0.01) (Table 5).The results indicated an adequate test-retest reliability for the Ch-MCOI.

Convergent and concurrent validity
The Average Variance Extracted (AVE) values corresponding to the HCO, SDCO, ADAC, and LIC are 0.64, 0.74, 0.60, and 0.63 respectively.As stated before, AVE ≥ 0.5 confirms the convergent validity.The convergent validity of the Ch-MCOI is established since all the AVE values of the four factors are greater than 0.50.www.nature.com/scientificreports/ Regarding the concurrent validity of the Ch-MCOI, we found that both the Ch-CD-RISC and Ch-WEM-WBS were positively correlated with the Ch-MCOI's SDCO subscale, whereas both the Ch-CD-RISC and Ch-WEMWBS were negatively correlated with the Ch-MCOI's ADCA.Furthermore, both the Ch-APS discrepancy subscale and high standards subscale were positively correlated with both the Ch-MCOI's HCO subscale and ADCA subscale, while both the Ch-APS high standards subscale and order subscale were positively correlated with the Ch-MCOI's SDCO subscale.In addition, the Ch-APS high standards subscale was negatively correlated with the Ch-MCOI's LIC subscale.Finally, all five Ch-MPS-f subscales were positively correlated with both the Ch-MCOI's HCO subscale and SDCO subscale, whereas the four Ch-MPS-f subscales were positively correlated with both the ADCA subscale of the Ch-MCOI.However, the organization subscale was negatively correlated with the Ch-MCOI's LIC subscale.The Ch-CAS benign competitive attitude subscale was positively correlated with the Ch-MCOI's SDCO subscale, while the Ch-CAS negative competitive attitude subscale correlated positively with the Ch-MCOI's HCO subscale (Table 6).
To summarize, the correlation tendency between the four subscales and these measurements was similar to that reported by Orosz et al. 27 , verifying that the Ch-MCOI had good concurrent validity.

Gender effects
Before evaluating whether there is a gender effect on the Ch-MCOI scores, we conducted invariance tests to check for equivalence across genders.Participants were split into a male group (N = 567) and a female group (N = 554).As shown in Table 7, a moderate model fit was obtained for both groups (CFI ≥ 0.92, RMSEA ≤ 0.09, SRMR ≤ 0.06), following the suggestion by 46 .Then, the test for the configural invariance (M0) supported a moderate fit to the data across gender groups (CFI = 0.94, RMSEA = 0.08, SRMR = 0.06), which can act as a baseline model to compare subsequent models 44 .Next, we assessed metric invariance (M1) by constraining all www.nature.com/scientificreports/factor loadings to be equal across gender groups.The metric invariance could be assumed across gender groups as evidenced by a nonsignificant drop in model fit (ΔCFI = 0.01, ΔRMSEA = 0.00, ΔSRMR = 0.00), according to practical fit indices: ΔCFI, ΔRMSEA, and ΔSRMR are within the threshold of ≤ 0.01 47,48 .Finally, we evaluated scalar invariance (M2) by constraining the item intercepts to be equal across gender groups.The scalar invariance could also be assumed across gender groups as evidenced by a nonsignificant drop in model fit (ΔCFI = 0.01, ΔRMSEA = 0.00, ΔSRMR = 0.00).Therefore, these results indicate that the factor structure, factor loadings, and intercepts of the Ch-MCOI were invariant across gender groups.Based on the results described above, we further performed the independent sample t-test to assess how gender affects scores on the Ch-MCOI.Our results revealed that Chinese males achieved a significantly higher mean score on both the HCO subscale (t (1074) = 8.03, p < 0.001) and the SDCO subscale (t (1119) = 7.68, p < 0.001) than Chinese females.In contrast, Chinese females achieved a significantly higher mean score on the ADCA subscale than Chinese males (t (1113) = 5.58, p < 0.001) (Table 8).

Discussion
This study clearly demonstrated that the Ch-MCOI has appropriate psychometric properties.Specifically, it has solid convergent validity, strong internal consistency, and temporal stability.Each factor of the Ch-MCOI demonstrates a meaningful relationship pattern with mental well-being, resilience, and perfectionism.In comparison with the English version of the MCOI, the Ch-MCOI achieved similar results for resilience, except for the lack of interest in competition.
The Ch-MCOI, similar to the original English version, could replace conventional monistic or dualistic measurements of competition 49,50 as the LIC subscale had a significant negative correlation with both a positive and negative competitive attitude 21 .The HCO subscale only had a positive correlation with a negative competitive attitude.The ADCA subscale had a negative relationship with a positive competitive attitude and a positive relationship with a negative competitive attitude.Conversely, the SDCO subscale had a positive correlation with a benign competitive attitude and a negative correlation with a negative competitive attitude.It shows the four different facets of competition have a diverse pattern with the negative and positive aspects of competition and it underlies the necessity of using multidimensional competitive measurement tools.In addition, regarding the Chinese sample, the LIC could not predict resilience.The SDCO was positively related to almost all factors of perfectionism, in line with prior studies 9,51 .The HCO was also related to the most negative aspect of Perfectionism.The LIC was negatively related to High Standards subscale, which is different from the original version, and had no relationship with Perfectionism characteristics, in line with expectations.
Compared to the original version, Chinese respondents scored relatively high on the LIC and ADCA subscales and relatively low on the SDCO subscale.Surprisingly, Chinese participants scored higher than Hungarians on the HCO subscale.One of the reasons for this could be the competitive societal environment in China.As a consequence of the rise of the socialist market economy and the burgeoning of the Chinese population, young Chinese confront intense competition today.They must engage in neijuan (irrational competition) with others, but they must also win or they could easily lose their jobs 24 .Due to the pressure to compete with others, they are unable to enjoy competition.This might be related to the combination of relatively low self-developmental competitive orientation and strong hyper-competitive pressures.Meanwhile, the LIC scores were also inversely associated with High Standards of Perfectionism scores.This link was not significant in the Hungarian sample.This result might be consistent with the Taoist philosophy: "When there is no desire, all things are at peace" (LaFargue, 1994).To summarize, it appears that a growing percentage of young people are exhausted by competition and want to "Lie Flat".Similarly, scores of the ADCA in the Chinese sample were inversely correlated with well-being and positively correlated with maladaptive Perfectionism.It may be inspired by Confucianism, which holds that those who like competition are not Junzi 20 and may be under more moral strain.This is in line with previous studies showing that all Junzi characteristics are adversely correlated with hyper-competitiveness (Ge et al. 20 .It is possible to interpret hyper-competitiveness as a hallmark of xiaoren (which can be translated as "villain"), which is the opposite of Junzi.This can create an internal conflict among young Chinese adults who live in an extremely competitive social environment and who are trying to do so without becoming xiaoren, even if they have a strong desire to win.
Finally, the Ch-MCOI showed gender differences that were not observed in the original version.Males scored lower on the LIC subscale, HCO subscale, and the SDCO subscale, while females scored significantly higher on the ADCA subscale.These results are consistent with Confucian values.According to these values, women are discouraged from engaging in any type of competition or from being aggressive 52 .Even if they choose to compete, females feel much more moral pressure than men.

Strengths and limitations
To the best of our knowledge, this is the first study to examine the psychometric properties of the MCOI in the Chinese-speaking population.Another strength of this study is relatively the large sample of adults with an age range from 18 to 63 years old.However, the present study may potentially be limited by a questionable generalization of our results to the wider, general Chinese population in other regions such as Hongkong and Taiwan.Moreover, other forms of reliability and validity tests could have been employed to strengthen the evidence of its applicability to the Chinese-speaking population.This obviously motivates future research clarifying this issue.

Conclusion
In terms of factor structure, internal consistency, temporal reliability, and convergent validity, the Ch-MCOI seems to have suitable psychometric features.The results of the LIC and ADCA subscales may reflect cultural values as well as Taoism and Confucianism principles.Thus, it is a valid instrument for the evaluation of the different aspects of competition in the Chinese-speaking population.Future research could examine individual variations in competitiveness in educational, occupational, and health-related situations by using this measurement in the Chinese cultural context.In addition, researchers could also use this tool in combination with neuroscience to find neural processes associated with different competition facets. https://doi.org/10.1038/s41598-024-57359-6
