The findings of research conducted around the world indicate that the higher the level of stress associated with the COVID-19 pandemic in an individual, the greater the tendency to develop an addiction to the internet. The aim of this paper was to provide a brief overview of the available scientific findings on the impact of the COVID-19 pandemic on mental health and internet addiction. Methods: A sweep through available literature was performed using the database Medline via the PubMed interface for articles written in English, using keywords and MeSH terms "Internet addiction", "mental health" and "COVID-19". Results: With insight into the scientific literature on COVID-19, mental health, and internet addiction, we have concluded that during the COVID-19 pandemic, time spent on the internet increased.

This paper, which is one of the few in the world dealing with this topic, presented the psychologist's work based on the concepts of mentalization and internal working models (IWMs) of attachment, with an adolescent girl who was prone to nonsuicidal self-injury. Gaga, a student in the first grade of high school, had visible scars from cutting her hands on the inner sides of both forearms. Gaga told the psychologist that her mother believes that this is an attempt to draw attention to her problems, and even a suicide attempt. Together with Gaga, the psychologist made a formulation of her mental difficulties. The main aim of the psychologist's work with Gaga was to control unpleasant impulses and emotions, so as to eliminate self-injury. This aim has been achieved through three global tasks: 1) that Gaga, in the relationship with the psychologist, builds her IWMs as positive, so that she can see herself as a person who is worthy of the love and support of close people; 2) to develop a stable capacity for mentalization; 3) to apply this acquired skills in the interpretation of her affective experiences. The mentalizing approach in working with Gaga was based on an attitude of emotional warmth, acceptance and authentic interest in her inner world. The psychologist's work with Gaga led to her better self-control, which resulted in the cessation of her self-injury. In her work with a psychologist, Gaga acquired positive IWMs, which she transferred into other significant interpersonal relationships.

Exponential increase in the number of individuals using internet has been observed in last ten years. The term "internet addiction" (IA) describes a compulsive behavior associated with any online activity that disrupts everyday social interactions. Main aim of this research was to determine variables and development predictors of Internet addiction. A total of 1,669 respondents participated in this research; 1,040 of them (62.3%) were female, 590 (35.4%) were male, and 39 (2.3%) did not want to declare their gender. The average age of the respondents was 15.09±1.757. Data were collected using an online form consisted of demographic data, questions related to the use of the Internet, the Internet Addiction Scale, and the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-auto questionnaire version (TEMPS-A) for adolescents. According to the findings of the present study, the relationship between Internet addiction and age, addictive substance use frequency, purpose, time spent on the internet, and type of temperament has been proven. Analysis results indicate that the risk of developing internet addiction is higher if an adolescent spends 1-3 hours and more than 3 hours daily (2.8 and 8.2 times, respectively). Increasing age numbers for 1 unit (year), the risk of internet addiction developing is decreasing by 11.3%. Hyperthymic temperament type decreases the risk of 70.9% of internet addiction developing. It is important to highlight importance of our results since practitioners can utilize our findings to create targeted treatments and prevent internet addiction in adolescents.
