- Description: Background: Pornography Use (PU) has been defined as the viewing of explicit materials in the form of pictures and videos, in which people are performing intercourse with clearly exposed and visible genitals. The prevalence of PU has increased dramatically among adolescents, partly attributed to the wide availability of such online material. Objective: The aim of this systematic literature review is to map the research interest in the field and to examine whether statistically significant results have emerged from the areas of research focus. Methods: To address these aims: a) the PRISMA guidelines are adopted and; b) an integrative conceptualization (derived from the merging of two widely accepted models of understanding of Internet use behaviours) was introduced to guide the synthesis of the findings. Results: In total, 57 studies were integrated into the present literature review. Findings were concep-tualized/ classified into individual, contextual and activity factors related to PU in adolescence. In that context, individual associated factors, such as development, victimization, mental health and religiosity, appear to have primarily captivated research interest demonstrating significant relationships with adolescent PU. Conclusion: Results indicate that more research focus on contextual and activity related factors is required to improve the level of understanding of adolescent PU and to inform a more holistic conceptual framework of understanding of the phenomenon during adolescence that could potentially guide future research.

- Description: A meta-analysis of up to 20 datasets is reported that examined the relationships between Cloninger's personality dimensions and Attention Deficit Hyperactivity Disorder (ADHD). Cloninger's model comprises four temperament (Novelty-Seeking, Harm-Avoidance, Reward Dependence, and Persistence) and three character (Self-Directedness, Cooperation, and Self-Transcendence) dimensions. Major findings were that all personality dimensions, except Self-Transcendence, were significantly associated with ADHD. These associations had different directions and magnitudes of relationship with ADHD. The associations were especially strong for Novelty-Seeking and Self-Directedness, being positive for Novelty-Seeking and negative for Self-Directedness. In addition, the association between ADHD and Persistence was moderated by age (stronger in children than adults) and source (stronger in clinical samples than community samples). Further, the association between harm avoidance and ADHD was moderated by age (strong and significant in adults, but not significant in children). Findings are discussed in relation to past work and the different strengths of the associations found between Cloninger's personality dimensions and ADHD, developmental differences in these relationships, implications for theoretical models of ADHD, the influence of biological and environmental factors in the expression of ADHD, implications for treatment and diagnosis, and the underlying processes for the relationships between personality and ADHD. © 2016 Elsevier Ltd

- Description: Over the past two decades, many problematic/excessive behaviours have increasingly been conceptualized as addictions due to their similarity with more traditional psychoactive substance addictions. The primary aim of the present study was to simultaneously examine the factor structure of three psychoactive substance addictions (alcohol use, cigarette smoking, and substance use) and seven behavioural addictions (sex, social media use, shopping, exercise, online gambling, internet gaming, and internet use), using exploratory factor analysis (EFA; N = 481) and confirmatory factor analysis (CFA; N = 487). A total of 968 participants completed an online survey including ten psychometric scales assessing the ten different potentially addictive behaviours. EFA supported a two-factor solution, with different factors for the psychoactive substance and behavioural addictions (excluding exercise addiction). CFA supported the two-factor model in a separate sample. There was good support for the concurrent and discriminant validities of the CFA latent factors and the reliability of the behavioural latent factor in the two-factor CFA model. While there was support for the concurrent and discriminant validities of the psychoactive substance latent factor, there was insufficient support for its reliability. The taxonomic, theoretical, and clinical implications of the findings are discussed. © 2022
