[Internet Addiction and Suicidality - A Comparison of Internet-Dependent and Non-Dependent Patients with Healthy Controls]. / Internetabhängigkeit und Suizidalität ­ ein Vergleich Internet-abhängiger und nicht abhängiger Patienten mit einer gesunden Population.

BACKGROUND: Internet addiction (IA) is associated with a high level of comorbid mental disorders and significant distress. With regard to the resulting hazardous potential, the present study examines the prevalence of suicidal ideation and behavior in a population with IA compared to a clinical and a healthy sample. METHODS: 60 patients with Internet addiction, 29 with and 31 without comorbid mental disorder were compared to an outpatient sample with other mental disorders (n=35) and 57 healthy controls regarding symptom load and suicidality. RESULTS: 48.3% of the patients with Internet addiction (with and without comorbidity) exhibited significantly more often suicidal symptoms as compared to healthy controls (3.5%). The level of both suicidal symptoms was significantly higher in all clinical samples in comparison to healthy controls , whereas no significant differences were shown between the clinical samples. For patients with Internet addiction and comorbid disorders a significant positive correlation between the level of Internet addiction and the extent of suicidal ideations were found. DISCUSSION: The results contribute to the notion that Internet addiction is associated with an increased risk for suicidal ideation and therefore represents a serious mental illness. Internet addiction is comparable to other mental disorders in terms of symptom load, impaired quality of life and suicidality. Larger samples have to be examined to clarify the question of mediating and moderating variables with regard to suicidality. CONCLUSION: A diagnostic workup and treatment regime for patients with Internet addiction should include an exploration of suicidality, not least because of possible risks in withdrawl.

[Internet Addiction, Suicidality and Non-Suicidal Self-Harming Behavior - A Systematic Review]. / Internetabhängigkeit, Suizidalität und selbstverletzendes Verhalten ­ Ein systematisches Review.

BACKGROUND: Internet addiction (IA) is associated with a high rate of co-morbid mental disorders, especially depression, anxiety disorders, ADHD and personality disorders and a considerable level of psychological strain. In terms of risk assessment, the present work investigates the current research literature on suicidal behavior and non-suicidal self-injurious behavior (NSSI). METHODS: We performed a systematic literature search in 14 databases on title and abstract level for the most common keywords for IA, NSSI and suicidality. After deduction of multiple items, 2334 articles remained. They were filtered per inclusion and exclusion criteria. We identified studies that examined the relationship between IA, NSSI and suicidality, which were assessed by validated psychometric instruments. This allowed a total of 15 studies to be included. RESULTS: The relationship between IA and suicidality was examined in 10 studies, four studies examined the relationship of IA, suicidality, and NSSI, and one study exclusively focused on IA and NSSHB. All studies showed higher prevalence for NSSI and respectively suicidality of the subjects with an IA compared to subjects without IA, with point prevalence varying considerably between 1.6-18.7%. DISCUSSION: The results of the included publications suggest that Internet dependency is associated with an increased rate of non-suicidal self-harming behavior and increased suicidality, with suicidal ideation being more closely related to IA than suicidal actions. In order to develop a better understanding of causal relationships between IA, NSSI and suicidality, further longitudinal studies are required. CONCLUSION: Against the background of the presented studies NSSHB and suicidality need to be explicitly addressed within the assessment and treatment of IA patients.
