Exploring the Dark side of conscientiousness. The relationship between conscientiousness and its potential derailers: perfectionism and narcissism

The current study aimed to identify what individual differences and situational variables cause derailment in highly conscientious people. Data were from a representative working sample of 716 participants across 27 industries, spanning both management and non-management roles. We tested four hypotheses with regard to bright- and dark-side personality traits and the relationship between boss/manager and staff member. Hierarchical linear regressions revealed mixed findings for Leader-Member Exchange (LMX) as a stressor. For maladaptive perfectionism it was confirmed, but not for adaptive perfectionism or narcissism. Results suggest introverts may be more prone to maladaptive perfectionism, even with higher levels of conscientiousness if there are lower LMX levels. Overall, the findings suggest selecting for conscientiousness alone and discounting other personality traits and situational variables may be detrimental in practice. Further implications are discussed alongside the study limitations.


Introduction
The Big Five model has been the primary focus of personality research across organizational psychology (Barrick et al., 2001).There is an abundance of research linking personality to academic success (Poropat, 2009), career success (Judge et al., 1999), job performance (Hogan & Holland, 2003;Salgado, 1997), leadership emergence (Judge et al., 2002) as well as health related outcomes (Bogg & Roberts, 2004).
Meta-analyses also confirm this, citing conscientiousness as the most highly correlated trait with these outcomes (Sackett & Walmsley, 2014): estimates of correlations are from r = .20 to 0.30 (Hurtz & Donovan, 2000).Conscientiousness is often used as a proxy for motivation as extreme scores can be detrimental: recent research looking into this idea that there may be a dark side to bright side traits (Judge & LePine, 2007;McCord et al., 2014;Pierce & Aguinis, 2013;Smith et al., 2018).These studies suggest there may be a 'too-much-of-a-good-thing effect', whereby excessive scores of personality traits relate to negative outcomes (Widiger et al., 2002).Others within the literature suggest dark side personality better seen as derailment, whereby stress is most often the trigger for the specified negative outcome (Hogan et al., 2011).
To understand causes of stress, this study draws on the Job Demands-Resources (JD-R) model (Bakker & Demrouti, 2007), which has strong longitudinal and metaanalytic support in the literature (Lesener et al., 2019).JD-R views stress as arising from an imbalance between the two variables: job demands and job resources.Job demands are described by Demerouti et al., (2001, p. 501) as "physical, social, or organizational aspects of the job that require sustained physical or mental effort and are therefore associated with certain physiological and psychological costs".Common examples may include time and work pressure, role conflicts, or quantitative workload.Job resources are "those physical, psychological, social, or organisational aspects of the job that either/or (1) reduce job demands and the associated physiological and psychological costs; (2) are functional in achieving work goals; (3) stimulate personal growth, learning and development" (Demerouti et al., 2001, p. 501).

Dark side of conscientiousness
Conscientiousness has been shown to have a curvilinear relationship with performance, task performance, Organizational Citizenship Behaviours (OCB) and Counterproductive Work Behaviours (CWB) (Carter et al., 2016;Le et al., 2011).CWB is a construct that covers a range of acts or behaviors, such as withholding effort, absenteeism, interpersonal aggression, and theft which are harmful for organizations and their stakeholders (Bennett & Robinson, 2000).Several different categorizations and measurers of counterproductive behavior exists.
Other findings by Martocchio and Judge (1997) also posit how conscientiousness can lead to impaired learning via self-deception and self-efficacy.Interestingly, Boyce et al. (2010) longitudinal study of 9,570 participants also found higher levels of conscientiousness can result in significantly lower life satisfaction following unemployment, because conscientious people seek out a sense of personal accomplishment that work provides.They also value rules and structure to their lives usually provided in the workplace.Furnham (2017) found a significant relationship between higher conscientiousness scores and higher scores on the dark side trait Diligence on the HDS, which is relates to perfectionism.Diligence is essentially a sub-clinical manifestation of OCD.Evidence in the same study suggests a relationship with the Bold, scale from the HDS also known as narcissism.If conscientiousness is characterised by detail-orientation and ambition, then derailers would logically be highly perfectionistic and narcissistic.

Conscientiousness and perfectionism
Conscientiousness' link with perfectionism stems from simple lexical association, often with words such as 'stringent', 'overbookish', 'overcautious', 'tight' and 'leisureless' (Coker et al., 2002).Researchers have linked conscientiousness to Obsessive Compulsive Disorders (OCD) (Samuel & Gore, 2012;Samuel & Widiger, 2011;Stairs et al., 2012).Those who are very high in conscientiousness may be rigid and inflexible, thus being less adjustable to change (LePine et al., 2000).High levels of conscientiousness also likely accompany a focus on following rules and the defined role, possibly resulting in less innovation and opportunity to learn new skills (Tett, 1998).
Perfectionism is a complex construct itself, traditionally viewed as having two forms (Stoeber et al., 2009;Stricker et al., 2019).The first is a more adaptive form of perfectionism, which relates to individuals who have high personal standards for performance on themselves (Dunkley et al., 2012).This often is referred to as excellence-seeking (Harari et al., 2018), or perfectionistic strivings (Stoeber & Otto, 2006), as these individuals escalate in their goal setting to higher and higher goals on themselves in order to derive self-worth.The secondary form is maladaptive form of perfectionism which relates more so to failure-avoiding (Harari et al., 2018) or perfectionistic concerns (Stoeber & Otto, 2006).
Overall, perfectionism is believed to have a net negative effect on both the individual and organization, particularly failure-avoiding perfectionism, and evaluative concerns (Harari et al., 2018;Hill & Curran, 2016).We hypothesised: H1 Conscientiousness will be positively correlated with adaptive perfectionism.H2 Conscientiousness will be negatively correlated with maladaptive perfectionism.

Conscientiousness and narcissism
Furnham (2017) also found a significant relationship between conscientiousness and the 'bold' construct on the HDS, which relates to narcissism (Furnham & Crump, 2005;Saulsman & Page, 2004) also found a slight negative relationship, although this may be explained to the metaanalysis focusing on DSM criteria rather than subclinical traits.
Like perfectionism, Narcissism is also believed to comprise of two forms (Miller et al., 2011).For the purposes of this study, the focus is on grandiose narcissism.Vulnerable narcissism is more neurotic, while grandiose narcissism is more attention-seeking (Morf & Rhodewalt, 2001).This study hypothesizes this attention-seeking may be interpreted as excessive goal setting and achievement-orientation, hence the link between conscientiousness and narcissism.
Narcissism has been linked with negative effects such as engaging in more CWBs (Grijalva & Newman, 2015) however, narcissists believe they do not engage as often in such behaviours (Judge et al., 2006).In the context of subclinical narcissism, like perfectionism, it is not always a negative trait.Furnham et al. (2012) found narcissism to be positively related to certain areas of potential such as sales, while other studies have shown those scoring higher on the bold trait of the HDS (i.e., narcissists) are more likely to have shorter times to promotion (Furnham et al., 2013).H3 Conscientiousness will be positively correlated with grandiose narcissism.

LMX as a Stressor
We also focus in this study on the relationship between a worker and his/her boss or leaders often known as Leadermember exchange (LMX) This study conceptualises low Leader-member exchange as a missing job resource and thereby becoming a stressor drawing on the JD-R model.That is, a good relationship with one's boss is benefit, but a bad one a stressor.LMX is a relationship-based approach to leadership that is centred on the two-way relationship between leaders and followers (Graen & Uhl-Bien, 1995).LMX has been shown, through meta-analysis, to be consistently positively correlated with job performance, satisfaction (both overall and supervisory), commitment, role perceptions and negatively correlated with turnover intentions (Gerstner & Day, 1997).
A meta-analysis by Martin et al. (2016) suggests that the costs of low LMX could be more significant than originally suspected as neglected followers may be more likely to engage in CWBs.Bakker et al., (2005) also demonstrated the effect of high-quality relationships and social support on buffering the impact of other stressors on individuals, suggesting high LMX to be a job resource.Consequently, low LMX is posited to be a potential stressor.Perceived social support has been found to mediate the relationship with perfectionism, with higher support leading to lower levels of distress (Dunkley et al., 2000).H4 LMX will be negatively related to adaptive and maladaptive perfectionism.
Interpersonal conflict at work has been shown to negatively impact self-esteem and be a stressor (De Dreu et al., 2002).Narcissism was shown to moderate the levels of CWB against the organisation and towards individuals, with higher narcissism resulting in higher levels of CWB (Meurs et al., 2013;O'Boyle et al., 2012, p.5) found that the relationship between narcissism and CWB was weakened in organizational cultures that "emphasize duty and loyalty to the organization and its members, cohesiveness among coworkers and relatedness among peers".This suggests that when there is a culture of high LMX, there may be a lesser risk of narcissism.H5 LMX will be negatively related to narcissism.

Interactive Effects of individual differences and situational variables
Regarding perfectionism, conscientiousness is expected to be the strongest predictor of personal standards and adaptive perfectionism (Dunkley et al., 2012;Smith et al., 2019;Furnham & Crump, 2005) also found this relationship between self-oriented perfectionism and extraversion and conscientiousness but no relationship between low agreeableness and self-oriented perfectionism as had been expected.Extraversion was expected to be positively related to adaptive perfectionism (Rice et al., 2007).Like LMX being a situational factor, extraversion is considered an individual difference influencing the conscientiousness and perfectionism relationship.
Regarding maladaptive perfectionism there is an expected negative relationship between extraversion with failure-avoiding and maladaptive perfectionism (Rice et al., 2007;Smith et al., 2019).

H6a Extraversion will positively moderate the LMX effect between conscientiousness adaptive perfectionism, as measured by the Standards subscale.
H6b Extraversion will negatively moderate the LMX effect between conscientiousness and maladaptive perfectionism, as measured via the Discrepancy subscale.

High potential traits inventory (HPTI)
The HPTI measures personality traits in the organisational workplace settings (MacRae & Furnham, 2020).Previous research has shown the HPTI relates to both objective and subjective measures of workplace success (Furnham & Impellizzeri, 2021;Teodorescu et al., 2017).There are 12 items measuring conscientiousness with an alpha of 0.82.It was favoured over other measures of conscientiousness because it focuses specifically on behaviour at work.

Extraversion -big-five factor structure
Extraversion was measured using the Big-Five Factor I, which related to surgency or extraversion (Goldberg, 1992).This was accessed online via the International Personality Item Pool (IPIP) (Goldberg et al., 2006).It is a 10-item scale and has a Cronbach's alpha of 0.87.

Narcissistic personality inventory (NPI-16)
Narcissism was measured using a shortened 16 item version of the NPI (Ames et al., 2006), which is based on the original scale by Raskin and Terry (1988).The NPI-16 has a Cronbach's alpha of 0.72, compared to the original NPI-40's 0.84.The NPI-16 correlates with the NPI-40 scale at 0.90 and maintained good levels of test-retest reliability 0.85 (Ames et al., 2006).It is essentially a measure of grandiose, rather than vulnerable, narcissism.
However, similarly to perfectionism as was discussed earlier, Furnham and Crump (2014) found only a single facet of agreeableness to be linked with narcissism, while all the facets of extraversion correlated positively.
For the purposes of this study, the focus on being broad traits, extraversion rather than agreeableness will be used as a moderating variable.Extraversion has been shown to be the most strongly correlated personality factor of the Big Five with grandiose narcissism (Mathieu, 2013;Zajenkowski & Szymaniak, 2019).As previously discussed, grandiose narcissism reflects an individual who is often overconfident, attention-seeking, highly extraverted, dominant, and interpersonally exploitative.This echoes the description of extreme ends of extraversion with phrases such as selfaggrandizing and egotistic (Coker et al., 2002).Those who score high on dominance and assertiveness, which is a facet of extraversion may be viewed as a tyrant as shown in a study by Ames and Flynn (2007) who found high levels of assertiveness were not conducive to leadership.This study predicts extraversion will positively moderate the relationship between conscientiousness and narcissism when LMX is low.

Procedure
Participants were recruited through a UK based psychometric company via email, having signed up to volunteer for future research projects.The questionnaire was created online using a university account of Qualtrics.Participants were sent instructional text for each section of the questionnaire and advised it would take between 10 and 15 min to complete.Consent was provided by all participants before engaging in the study at the beginning of the questionnaire.

Analyses
New codes were created for Managerial Level to transform the variable into ordinal data and allow for more statistical tests such as correlations.The new codes were 1 (Administrative), 2 (Professional/ Non-Management), 3 (First-Line Management), 4 (Middle Management), and 5 (Executive/ Senior Management).In doing this, 69 cases were excluded with answers such as 'I don't know' and 'Other management', as these could not be categorized into the ordinal structure and would not allow further statistical tests.
Using Rice and Ashby's (2007) classification of scores on the APS-R, those with scores of 42 and above on the standards subscale are classified as adaptive perfectionists.Those with scores below 42 are considered non-perfectionists.Individuals with scores of 42 and above on the Standards subscale and scores of 42 and above on discrepancy, may be classified as maladaptive perfectionists.Similar cutoff points were also found by Rice & Richardson (2014) across the groups of perfectionism in a non-university population.

Descriptives and correlations
Pearson's product-moment correlation coefficient analyses were run to assess relationships across all the study variables (see Table 1).It shows conscientiousness highly correlated with standards and order, extraversion with narcissism, and standards with order and perfectionism.H1, H2 and H3 were initially tested with correlations to investigate the relationship between conscientiousness, standards, discrepancy, and narcissism.In support for H1, a significant strong positive correlation was found between conscientiousness and standards.In support of H2, a significant negative relationship was discovered between conscientiousness and discrepancy.Finally, in support of H3, a significant positive relationship between conscientiousness and NPI scores.With respect to H4, mixed results were found.LMX was shown to have a have a significant negative relationship with discrepancy, which was expected.However, LMX was found to have a significant positive relationship with Standards, which was surprising.Interestingly, standards and discrepancy were positively correlated which is contrary to previous research showing a negative correlation (Rice et al., 2011).Contrary to H5, there was a significant positive relationship between LMX and NPI scores, compared to the hypothesized negative relationship.Age was also checked for correlations with narcissism and perfectionism, as previous research has shown a slight negative relationship (Twenge et al., 2008).This was to ensure age effects would not impact the hierarchical regressions in the next step.

Hierarchical regressions
To further investigate the relationships observed in the Pearson's correlations table a series of hierarchical regressions were carried out to test the hypotheses.The regressions helped identify how interpersonal differences in extraversion, as well as situational variables i.e., LMX, may predict the derailment above and beyond conscientiousness alone.Within each of the hierarchical regressions, gender and age were entered in the first step of each regression to establish if the independent variables were able to predict over and above the scores for gender and age.

Discrepancy
To investigate H6a, a hierarchical regression was carried out to assess if extraversion and LMX moderated the relationship between conscientiousness and Discrepancy i.e., maladaptive perfectionism.Preliminary analyses indicated that the assumptions required for multiple linear regression were met with Cook's distance below 1, Durbin Watson statistic of 2.054, VIF values below 10 and Tolerance values above 0.2.Full results are shown in Table 2.
Results of the hierarchical linear regression, shown in Table 2, indicated that there was a collective significant effect for the overall model, explaining 10% of the variance of maladaptive perfectionism.
Step one involved inputting age and gender to ensure the following steps would predict discrepancy over and above age and gender effects.Conscientiousness followed in step two and was a significant positive predictor, but extraversion in step three was the largest predictor of the model.LMX in step four and was also a significant predictor.At step five the interaction variables were entered into the model, with conscientiousness and extraversion, being the only significant predictor of the three interactions.Finally, the interaction between conscientiousness, extraversion and LMX was added in step six, which was a

Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 significant predictor above and beyond the other variables in the model.As hypothesized there was a significant interaction effect between conscientiousness, extraversion and LMX, negatively predicting scores on discrepancy.Overall, support for H6a was observed.

Standards
To investigate H6b, a hierarchical regression was carried out (See Table 3) to assess if extraversion and LMX moderated the relationship between conscientiousness and Standards (i.e., adaptive perfectionism).Preliminary analyses indicated that the assumptions required for multiple linear regression were met with Cook's distance below 1, Durbin Watson statistic of 2.022, VIF values below 10 and Tolerance values above 0.2.Full results are shown in Table 3.
Results of the hierarchical linear regression indicated that there was a collective significant effect for the model, explaining 36.5% of the variance of standards, with conscientiousness accounting for the largest proportion of variance.
Step one involved inputting age and gender to ensure the following steps and variables would predict Standards over and above age and gender effects.Conscientiousness followed in step two and was a significant predictor, while extraversion and LMX were added in step three and four, respectively.LMX was found to be a significant predictor while extraversion was not.At step five the interaction variables were entered into the model but were not found to be significant.Finally, the interaction between conscientiousness, extraversion and LMX was added in step six.There were no significant interaction effects across the model, suggesting conscientiousness and LMX are independent contributors to standards.
Those who are low in LMX and conscientiousness, appear to have lower personal standards, which suggests these individuals may be less motivated and driven comparing to those with higher scores.By promoting and investing in activities to foster higher LMX levels in those with lower conscientiousness scores, there may be a possibility to improve these individual's personal standards.Despite the independent contributions of conscientiousness and LMX, overall, support for H6b was not observed.

Narcissism
To investigate H7, a hierarchical regression was carried out to assess if extraversion and LMX moderated the relationship between conscientiousness and narcissism.Preliminary analyses indicated that the assumptions required for multiple linear regression were met with Cook's distance below 1, Durbin Watson statistic of 1.984, VIF values below 10 and Tolerance values above 0.2.

Table 3 Hierarchical Linear Regression Analysis for Variables Predicting Standards
Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Results of the hierarchical linear regression indicated that there was a collective significant effect for the overall model but that there were no interaction effects among the variables.Step one involved inputting age and gender to ensure the following steps would predict narcissism over and above age and gender effects.Conscientiousness followed in step two as a significant predictor, as was extraversion in step three.LMX was added in step four but was not found to be significant.At step five the interaction variables for conscientiousness and extraversion, conscientiousness and LMX, as well as LMX and extraversion were entered into the model.
Finally, the interaction between conscientiousness, extraversion and LMX was added in step six.Conscientiousness and extraversion were observed to independently contribute to NPI scores, with higher levels of each, predicting higher levels of narcissism.LMX was not found to be a significant predictor in the model, higher.Overall, these results did not support the expected H7 (see Table 4).

ANOVA -perfectionism
Rather than just looking at each subscale of the APS-R in isolation, as was done in the regressions, participants were grouped using Rice and Ashby's (2007) scoring classification system on the APS-R for adaptive and maladaptive perfectionists, as well as non-perfectionists.The current study found a slightly higher proportion of maladaptive perfectionists 30.2% maladaptive, compared to previous studies at 26.9%.This was offset with slightly lower adaptive perfectionists at 32.5% compared to 40.7% and non-perfectionist 37.3% compared to 32.4% (Rice & Ashby, 2007).The three groups were then analysed via a one-way ANOVA to compare differences across the three groups in each of the study variables.
As Levene's test of homogeneity of variance revealed most variables did not have equal population variance.Hence, a Welch's ANOVA was used for this reason to calculate Welch's F to ensure more accurate statistics (Cribbie et al., 2012).This likely arises from the unequal group sizes across the conditions.Despite some of the variables being slightly skewed, being the sample sizes were large enough beyond 160 cases per group to avoid issues of normality (Wilcox, 2010).Research also shows the ANOVA to be robust even in non-normally distributed data (Schmider et al., 2010).
With respect to standards, no significant difference was found between adaptive and maladaptive perfectionists.However, significant differences were found at p < .05 between non-perfectionists, perfectionists and the other two groups, scoring much lower than these groups.Regarding order, there was no significant difference observed between

2012).
Being discrepant relates to the concern between performance and expectation.It is likely neuroticism is the strongest predictor of discrepancy because anxious individuals would worry most about not achieving their goals and targets (Smith et al., 2019).
With respect to the positive relationship between conscientiousness and narcissism, the current results were in line with the literature.This suggests those who may be highly goal-oriented and achievement-oriented may be at more risk of narcissistic derailment, although the relationship is much weaker than for perfectionism.That is, the positive results of conscientiousness may lead workers to become hubristic.

Evidence of LMX as a Stressor
The major finding of the study relates to the interactive moderating effect of extraversion and LMX on the relationship of conscientiousness and discrepancy.Support was found for the hypothesis that LMX moderates the relationship between personality and discrepancy, particularly at lower levels of conscientiousness and extraversion.These results may suggest that introverts may be more prone to maladaptive perfectionism and even with higher levels of conscientiousness if there are lower LMX levels.Conversely, at higher levels of conscientiousness and extraversion, higher LMX is observed to further reduce the levels of discrepancy, suggesting this social support may have a buffering effect on maladaptive perfectionism.This is in line with what was hypothesized utilizing the JD-R model (Bakker & Demrouti, 2007), that by providing better job resources such as improved LMX, it may be possible to reduce maladaptive perfectionism.
This suggests greater care may be advised for managers in organisational settings who have introverted yet highly conscientious team members.On the outward appearance they may be seen as hard-working and driven colleagues adaptive and maladaptive perfectionists.Significant differences were found at p < .05 between non-perfectionists and the other two groups, scoring lower than both adaptive and maladaptive perfectionists.For discrepancy there were significant differences at p < .05found across all three groups with maladaptive perfectionists scoring significantly higher than both other groups and adaptive perfectionists scoring the lowest compared to non-perfectionists.
Next to LMX, no significant difference was found between non-perfectionists and maladaptive perfectionists.However, significant differences at p < .05were found between adaptive perfectionists and the other two groups, scoring much higher than the others.Regarding narcissism, there was no significant difference found between adaptive and maladaptive perfectionist groups.There were significant differences found at p < .05 between non-perfectionists and the others, with non-perfectionists scores lower than both groups.

Discussion
As expected, conscientiousness did show a positive relationship with both standards subscale and narcissism, which is in line with previous research.Individuals who may be described as highly diligent, industrious, and thorough are also likely to derail through excessively high personal standards and perfectionistic strivings (Stoeber & Otto, 2006).Conscientiousness was also found to have a negative relationship with the discrepancy subscale, which was as anticipated based on previous studies.This may be explained at the facet level of conscientiousness, with higher levels of competence and self-discipline shown to be the main driver of this negative association as these individuals are totally focused and confident in their ability, and hence less prone to the perfectionist or evaluative concerns (Dunkley et al.,  relationship observed, which was contrary to the hypothesis.This is surprising as research has shown those higher in narcissism are likely to have lower levels of concern for others, hold a negative view of others, often with a tendency to focus on dominating others and their adversarial orientation towards them (Paulhus, 2001).It is suggested that narcissists reject intimacy, lack empathy, and seek applause and when threatened tend to derogate others (Stucke & Sporer, 2002).Bushman and Baumeister's (1998) study, which examined interpersonal interactions between narcissists and other individuals, found a positive relationship between narcissism and hypervigilance to threats, which then led to aggressive behaviours.
However, much of this research often focuses on vulnerable narcissism, which involves a higher level of otheroriented narcissism rife with neuroticism (Zajenkowski & Szymaniak, 2019).Hence, the more grandiose narcissism may view LMX as a positive reflection on the individual, and there may be under-reporting of problems in LMX much like the underreporting of workplace deviance (Judge et al., 2006).Perhaps as this study used the NPI-16, thereby not being able to look at the facet level of narcissism and identify potential relationships with LMX such as Leadership/Authority facets which were related to social support in Rhodewalt and Morf's (1995) study.This may be a promising future research study to investigate the facet level of narcissism alongside the facet level conscientiousness.
The results of the current study show a different pattern compared to a clinical population, which tend to show narcissism to be mainly linked with low trait agreeableness, whereas this study showed the narcissist to be conscientious and extraverted.This is in line with previous suggestions that the subclinical narcissism measure may be tapping into the profile of what may be a successful manager (Furnham, 2010;Howard & Howard, 2001).Further to this, Furnham et al. (2016) found narcissism was positively linked with management and sales potential.Others have also linked narcissism to leadership emergence (Brunell et al., 2008).
Extraversion was found to be a key factor in linking conscientiousness with perfectionism and narcissism.In the case of socially prescribed perfectionism, higher extraversion reduced the discrepancy scores and chances of maladaptive extraversion.However, high extraversion and high conscientiousness individuals may be more at risk for narcissism derailment.This highlights how it is important to not view derailers, personality traits and outcomes in isolated siloes (Penney et al., 2011), rather it is better to acknowledge where strengths in one area may become risks in other areas.Research has linked narcissism with forms of perfectionism, so it is possible the two can manifest together and are not necessarily discrete.The observed positive relationship between narcissism and the standards subscale was in who get on with their tasks, but they may be susceptible to socially oriented maladaptive perfectionism behaviours, ruminating on perceived standards of others, while not seeking out help and interaction with their manager to resolve matters and the manager being oblivious to the situation.Lesener et al. (2019) suggest fostering environments that create a resource-oriented working environment including regular feedback sessions with managers, more cooperative working conditions, proactive promotion of learning opportunities, variety in job tasks, and an increase of autonomy for both individual and team.

Positive relationship of LMX with Derailers
Conscientiousness was shown to account for a large proportion of the variance of Standards link to adaptive perfectionism, which is in line with previous findings (Smith et al., 2019).In this circumstance LMX does not appear to be a stressor, but in fact a positive predictor of personal standards.This may be explained as managers are likely to promote and reward these types of behaviours displayed by conscientious individuals in organizational settings, whereby the higher personal standards may result in a more engaged LMX relationship (Stoeber & Damian, 2016).However, it was surprising that extraversion was not related as it was hypothesized that higher extraversion would relate to higher standards via the assertiveness and high energy associated with extraversion, which in turn would be related to motivational intentions for status striving (Barrick, Mitchell & Stewart, 2003;Barrick , Mount & Gupta, 2003).One reason maybe that the measure of extraversion in this study differed from those in others studies by having more emphasis on affective rather than arousal needs.That is extraversion has different facets which some questionnaires emphasise more than others (Furnham, 2008).Similarly, highly conscientious, and highly extraverted persons are often described as ambitious, serious, and purposeful, which is similar to what one may imagine to be adaptive perfectionists (Hofstee et al., 1992;Johnson & Ostendorf, 1993).
Overall, the findings of this positive relationship suggest LMX has mixed support as a stressor.It raises the question that LMX may in fact be a product of the high standards and performance of an adaptive perfectionist.Clearly there are different aspects of an LMX which could in part be governed by both corporate culture as well as the nature of the work activity.
The findings concerning narcissism are in line with even the early work of Emmons (1987) who suggested it correlates positively with self-esteem, extraversion, dominance, and independence; and negatively with abasement, self-ideal discrepancy, neuroticism, and social anxiety, In terms of the moderating effect of LMX, there was a significant positive included in the article's Creative Commons licence and your intended use is not permitted by statutory regulation or exceeds the permitted use, you will need to obtain permission directly from the copyright holder.To view a copy of this licence, visit http://creativecommons. org/licenses/by/4.0/.line with previous findings (Smith et al., 2016).This relates back to comments in the literature on the link between conscientiousness and the bold derailer profile, suggesting the conceptualisation of this derailer to be the profile of a successful manager being stable, self-assured, extraverted and low agreeableness (Furnham, 2010;Howard & Howard, 2001).In practice, selecting personnel with higher conscientiousness and extraversion scores to avoid possible maladaptive perfectionists may result in those who are at risk of narcissistic derailment, which could also negatively impact the organization such as risk-taking behaviours (Buelow & Brunell, 2014).

Limitations
There are difficulties in classifying perfectionists (Rice & Richardson, 2014), with other cut-off scores used and suggested as well such as those for adolescent populations > 35 standards and > 45 discrepancy (Rice et al., 2011).This may raise questions on the usefulness of categorical cut-off scoring for the APS-R as those classified as non-perfectionists, may in fact have high levels of perfectionist concerns, which can be missed due to the labelling used.Another limitation of the study is that it is cross-sectional in nature, so extrapolating cause and effect is challenging.A further limitation may be that tenure within their current job role was not recorded.Finally, the study suffers from method-invariance relying exclusively on self-report, and it is always desirable to have observational and behavioural data to supplement self-report. .
