[Internet Addiction and Suicidality - A Comparison of Internet-Dependent and Non-Dependent Patients with Healthy...

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.

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.

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.

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.

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.
