Study addiction and 'dark' personality traits: a cross-sectional survey study among emerging adults.

Background: Research has shown that personality traits can have an important role in the development and maintenance of behavioral addictions. However, the relationship between dark personality traits (i.e., Machiavellianism, psychopathy, narcissism, sadism, spitefulness) and 'study addiction' has yet to be investigated.Objectives: The purpose of the present study was to examine the associations of dark traits with study addiction among the total sample, males, and females separately, while adjusting for the Big Five personality traits (i.e., extroversion, neuroticism, agreeableness, openness, conscientiousness).Methods: A total of 716 university students completed an online survey, including questions assessing the aforementioned variables.Results: Hierarchical regression analysis suggested that being female, neuroticism, conscientiousness, Machiavellianism, and sadism were positively associated with study addiction. However, dark personality traits (i.e., Machiavellianism, sadism) were significantly related to study addiction only in males but not in females.Conclusions: Findings of this preliminary study suggest that dark personality traits may be better at explaining male addictive studying patterns and that gender should be taken into account when investigating the role of personality in the development of study addiction.

The role of childhood emotional maltreatment and body image dissatisfaction in problematic smartphone use among adolescents.

Growing empirical evidence has identified specific psychological and contextual risk factors associated with problematic smartphone use (PSU). However, the potential direct and indirect impact of childhood emotional maltreatment (CEM) on PSU remains largely unexplored, despite the established role of CEM in the onset of other excessive, problematic, and addictive behaviors. Consequently, the purpose of the present study was to test the direct and indirect relationships of emotional abuse and neglect (two facets of CEM) with PSU via specific mediational pathways including body image dissatisfaction (BID), social anxiety, and depression. The sample comprised 443 adolescents who completed a questionnaire that included assessment tools of aforementioned variables. Multiple mediation model results indicated that CEM was directly and indirectly associated with PSU via BID, depression, BID-related depression, and BID-related social anxiety. Results suggested that emotionally traumatic experiences were associated with PSU in adolescents and that this relationship may partially be explained by BID and psychosocial risk factors. The present study draws caution to the amplifying roles of CEM and BID on increased PSU. The results of the study have important clinical and public health implications, but additional research is needed before interventions can be developed and implemented on the basis of present results.
