This study aimed to investigate the relationship between dark personality traits and insomnia by considering the mediated effects of perceived stress and ethical judgments. This descriptive and correlational study was conducted with 464 university athlete students from individual and team sports. Dark Triad Scale (DTS), Insomnia Severity Index (ISI), Perceived Stress Scale (PSS), and Moral Content Judgment in Sport Questionnaire (MCJSQ) were used. Significant correlation coefficients were observed between the dark personality traits and other variables. Regression analysis showed that psychopathy (about 19%) and ethical judgments (about 16%) could predict insomnia. It was shown that among dark personality traits, psychopathy along with ethical judgments could predict insomnia.

The purpose of the present investigation was to examine the relationship between multidimensional perfectionism and athlete burnout. The target population of research consisted of 168 elite handball players who participate in National Junior Championships. 123 athletes were selected randomly as the sample. We used a multi-section inventory to collect data, contained measures of multidimensional perfectionism, dispositional achievement goals, athlete burnout, perceived satisfaction with goal attainment and perceived coach satisfaction with goal attainment. In this study was used Pierson correlation and Hierarchical regression for the analysis of collected data. Regression analyses revealed that socially prescribed perfectionism demonstrated a significant positive association, and self-oriented perfectionism a significant negative association with burnout dimensions. In conclusion, in this study were not supported the hypotheses of the moderating influence of Perceived satisfaction with goal attainment and achievement goal orientations on the relationship between multidimensional perfectionism and athlete burnout.
