PurposeThe purpose of this paper is to examine the relationship between dark triad personality (DTP) and organizational and individual counterproductive work behaviors (CWB) and perceived career ...success among employees in Turkey. Additionally, the study examined the effects of four situational variables: perceived organizational politics, transparency, psychological contract breach, and accountability.Design/methodology/approachData were collected from 156 employees across five service organizations in Sakarya, Turkey, using the survey method.FindingsThe regression analysis findings showed that the three traits of the DTP, Machiavellianism, and psychopathy were significantly related to both organizational and interpersonal dimensions of the CWB. Narcissism was not related to any of the dimensions of CWB. The findings showed no significant relationship between any of the four situational variables and the two forms of CWB. However, three of the situational variables were related to perceived career success, while the three dimensions of DTP were not.Research limitations/implicationsThe main limitations of this study are its cross-sectional design and the self-reported measures of the dependent variables. Interestingly, the study showed that having high levels of DTP does not necessarily promote their careers.Originality/valueThis study contributes to examining career success as a dependent variable in addition to CWB. The findings showed that situational variables are related to career success, and DTP is related to CWB. This finding has both conceptual and practical implications.
The Dark Triad Dirty Dozen (i.e., DTDD), Short Dark Triad (i.e., SD3), and the Single Item Narcissism Scale (i.e., SINS) were adapted into Turkish and validated (N=368). We examined internal ...consistency, factor structures, and convergent and discriminant validity of the scales using the Mach-IV, LSRP, NPI-16, Rosenberg's self-esteem scale, and Big Five scales. The Turkish versions of the scales had good psychometric properties and can be used in further research.
•Psychometric properties of the DTDD-T, SD3-T and SINS-T are consistent with the original versions.•Internal consistency, factor structures, and convergent and discriminant validity of the scales were satisfactory.•The DTDD-T, SD3-T and SINS-T can be used in further research.
Although the Dark Triad has begun to be studied extensively, little is known about which of the Dark Triad traits is more malevolent in organizational context. Therefore in this study in order to ...compare the effects of Dark Triad traits on work-related attitudes, the effects of the Dark Triad traits (i.e., narcissism, Machiavellianism, and psychopathy) on counterproductive work behaviors (CWBs) (withdrawal, theft, and abuse) were examined. N= 244 employees participated in the study. Employees rated their own Dark Triad and CWBs. The results revealed that, in correlation analysis all the Dark Triad traits related to CWBs positively. Narcissism had the weakest correlation here (having only significant associations with withdrawal). However, according to the multiple regression findings, Machiavellianism and narcissism did not predict CWBs and only psychopathy predicted CWBs. Results were discussed and suggestions were made for further research. This study provided that comparing to narcissism and Machiavellianism, psychopathy could potentially be more malevolent in organizational context.
A primary contention of evolutionary models of the Dark Triad traits (i.e., narcissism, psychopathy, and Machiavellianism) is that they are adaptations for dealing with adverse socioecological ...circumstances. In this study (N = 557), we collected data from two countries that differ in socioecological conditions (i.e., Turkey and Australia). We measured perceptions of a dangerous and competitive world and individual differences in the Dark Triad traits. Turkish participants were higher in the Dark Triad traits than Australian participants were. All the Dark Triad traits were correlated with a competitive but not a dangerous worldview. Country-level differences in the Dark Triad traits were mediated by competitive worldviews, but not dangerous worldviews, and those effects were similar in each sex. And rates of narcissism depended on participant's sex and country. This study provided the first attempt to understand country-level differences in the Dark Triad traits using a life history framework.
•Turkish participants were higher on the dark traits than Australians.•Turkish participants had more competitive/dangerous worldviews.•Country-level differences were mediated by competitive worldviews.•These mediation effects were stronger in men than in women.•Sex differences in narcissism were only found in Australia.
Abstract
Personality traits have been extensively studied to understand different behavioral addictions. However, less is known about the relationship of employees’ dark personality traits and work ...addiction. The purpose of the present study was to examine the associations between the Big Five personality traits (i.e., extroversion, neuroticism, agreeableness, openness, conscientiousness) and dark personality traits (i.e., narcissism, Machiavellianism, psychopathy, sadism, and spitefulness) with work addiction. A total of 514 private sector employees completed a survey that included psychometric assessment tools for the aforementioned variables. Hierarchical regression analysis indicated that lower extroversion, lower openness to experience, higher narcissism, and higher spitefulness were positively associated with work addiction among private sector employees. The findings of the present study suggest that dark personality traits should also be taken into account in order to better understand work addiction among employees.
Background
Biochemical recurrence (BCR) can be seen in the early or late period after radical prostatectomy (RP). Various models have been developed to predict BCR.
Objective
In our study, we ...evaluated the accuracy of four pre‐operative models (GP score, PRIX, D’Amico risk classification, CAPRA) in predicting BCR after RP in Turkish patients.
Methods
Age, preoperative total prostate‐specific antigen (PSA) values, clinical stages, total number of cores taken in biopsy, number of positive cores, preoperative biopsy Gleason score (GS), follow‐up time and presence of BCR after RP were recorded. BCR was defined as a total PSA value >0.2 ng/dL twice consecutively after RP. Classifications or scoring was performed according to pre‐operative models. The 1‐, 3‐ and 5‐year BCR‐free rates of the patients were determined for each model. Also, the accuracy of four predictive models for predicting 1‐, 3‐ and 5‐year BCR was evaluated.
Results
For all pre‐operative models there was a statistically significant difference between risk groups in BCR‐free rates at 1‐, 3‐ and 5‐year after RP (P < .001). The Harrell's concordance index for 1‐year BCR predictions was 0.802, 0.831, 0.773 and 0.745 for the GP score, PRIX, CAPRA and D’Amico, respectively. For 3‐year BCR predictions, it was 0.798, 0.791, 0.723 and 0.714 for the GP score, PRIX, CAPRA and D’Amico and respectively. Finally, The Harrell's concordance index for 5‐year BCR predictions was 0.778, 0.771, 0.702 and 0.693 for the GP score, PRIX, CAPRA and D’Amico, respectively.
Conclusion
In the prediction of BCR, the accuracy of GP scoring and PRIX seems slightly higher than CAPRA and D’Amico risk classification. Surely our results should be supported by head to head comparisons within other larger cohorts.
Purpose
To investigate the effect of platelet-rich plasma (PRP) in reducing renal injury in ureteral obstruction.
Methods
Twenty-four Wistar Albino rats were randomized and divided into four groups ...as the donor (
n
= 6), sham (
n
= 6), saline (
n
= 6), and PRP (
n
= 6). Blood was obtained from the donor group by cardiac puncture and PRP was prepared. 2 cc blood was sampled from other groups to measure blood-urea nitrogen and creatinine levels. Baseline renal scintigraphy was performed. An abdominal midline incision was made and the left ureter was exposed in the sham group. Saline infusion was given to the kidneys of the saline group after left ureteral obstruction, while PRP was given to the PRP group. On postoperative Day 7, control biochemical and scintigraphic evaluations were performed and left nephrectomies were done. Left kidneys were evaluated histopathologically.
Results
DMSA measurements in the sham group were found to be significantly higher than the saline and PRP groups (
p
= 0.001 and
p
= 0.024, respectively). There were no significant differences between the saline and PRP groups (
p
= 0.525 and
p
> 0.05, respectively). Histopathologically, no significant difference was observed between the saline and PRP groups (
p
= 0.320), while the scores of the sham group were significantly higher than the saline and PRP groups (
p
= 0.02 and
p
= 0.001, respectively).
Conclusion
Our study results suggest that PRP may be effective in preventing ureteral obstruction-induced renal injury.
Abstract
Background
Testosterone plays a vital role in maintaining tissue homeostasis, and testosterone deficiency may potentially influence the likelihood of urethral stricture recurrence.
...Objectives
To evaluate the prognostic value of testosterone levels in the recurrence after direct visual internal urethrotomy in primary short segment bulbar urethral strictures and its clinical reflections.
Materials and methods
A total of 723 patients who underwent direct vision internal urethrotomy between January 2000 and October 2022 were retrospectively analyzed. After implying exclusion criteria, 116 patients with available data were enrolled. Patients were divided into two groups as recurrence and no recurrence. Age, stricture length, etiology, time of recurrence, diagnosis of previous diabetes mellitus, hypertension, smoking, body mass index, and total testosterone levels were recorded. Free testosterone and bioavailable testosterone values were calculated using total testosterone, albumin, and sex hormone binding globulin values. Hypogonadism was considered as a total testosterone level less than 300 ng/dL. Demographic characteristics and total testosterone, free testosterone, and bioavailable testosterone levels were compared between the two groups for statistical significance. The recurrence rates of patients with and without hypogonadism were compared.
Results
Recurrence was observed in 41.4% of the cases (
n
= 48). There was no statistically significant difference between the groups in terms of age, body mass index values, diabetes mellitus, hypertension, smoking status, presence of hypogonadism, and etiology (
p
= 0.745, 0.863, 0.621, 0.622, 0.168, 0.051, and 0.232). In terms of total testosterone levels and bioavailable testosterone levels, the recurrence group had significantly lower values (
p
= 0.018 and 0.04). There was no significant difference between the two groups in terms of stricture length (
p
= 0.071). Sixteen of 28 patients with hypogonadism had recurrence, whereas 32 of 88 patients without hypogonadism had recurrence (
p
= 0.051).
Discussion
Testosterone levels have potential to predict recurrence in primary short‐segment bulbar urethral strictures. This study represents the inaugural analysis of the impact of testosterone deficiency on recurrence within the cohort of patients with primary short‐segment bulbar urethral strictures.
Conclusion
Testosterone levels and ratios may serve as predictive factors for identifying recurrent cases in primary short‐segment bulbar strictures. For patients at a higher risk of recurrence, urethroplasty may be considered as an initial treatment option, even in cases of primary and short‐segment strictures.
