Functions of nonsuicidal self-injury in a Hungarian community adolescent sample: a psychometric investigation

Background The Inventory of Statements About Self-Injury (ISAS) is a psychometrically valid tool to evaluate the motives of nonsuicidal self-injury (NSSI), but there are a few studies that test gender differences in the factor structure of the measurement. However, several differences across gender were identified in NSSI (e.g., in prevalence, methods, functions). Therefore, our study focused on further analyses of the dimensionality of the ISAS functions. Methods Among Hungarian adolescents with a history of NSSI (N = 418; 70.6% girls; mean age was 16.86, SD = 1.45), confirmatory factor analysis and exploratory structural equation modeling frameworks were used to test the factor structure of the ISAS part II. Results Results support the two-factor structure of the questionnaire. Intrapersonal and interpersonal motivation factors emerged in the whole sample, but this factor structure varied across gender. Among girls, intrapersonal motivation of NSSI was associated with higher loneliness, more inflexible emotion regulation, and a more pronounced level of internalizing and externalizing mental illness symptoms. Conclusions Our findings provide sufficiently solid arguments for the need to examine NSSI functionality separately for adolescent girls and boys because there were clear gender differences in the motives underlying NSSI. In addition, precise scanning of patterns of NSSI functions may further help us to identify the most at-risk adolescents regarding self-injury.

Do Negative Emotions Matter? Paths From Victimization to Cyber and Traditional Bullying From a General Strain Theory Perspective

Drawing on theoretical propositions of general strain theory (GST), the current study aims to examine whether general victimization as a source of criminogenic strain predicts two different types of bullying, traditional and cyberbullying perpetrations, and whether negative emotionality, such as trait-based anger and depression, conditions the effects of general victimization on bullying. Using a Korean adolescent sample, we adopt cross-lagged dynamic panel models to investigate the longitudinal effects and interactions of strain and negative emotionality. The results indicate a significant influence of general victimization on both types of bullying perpetrations, as expected, while the conditioning effects of negative emotionality are found only for traditional bullying, which may reflect differences in the nature of the two different forms of bullying.

Validation of the Greek version of the Adolescent Sleep Hygiene Scale (ASHS)

Transition from childhood to adolescence is known to bring about many changes in the lifestyle and psycho-emotional state of adolescents. One of the major lifestyle factors that affect adolescents’ physical and mental health is sleep. The aim of this study was to validate the Adolescent Sleep Hygiene Scale (ASHS), a tool that measures sleep hygiene, in an adolescent sample living in Greece. The study’s sample consisted of 146 Greek adolescents aged 12-18 years. The Adolescent Stress Questionnaire was used for convergent validity and correlation with adolescents’ stress. The pilot and the main study demonstrated sufficient internal consistency. Exploratory Factor Analysis showed an adequate adaptation of the original ASHS questionnaire to the Greek adolescents. The findings of this study support the use of ASHS as a reliable and valid tool for evaluating sleep-facilitating and sleep-inhibiting practices of Greek adolescents.
