Background and aims

Behavioral addictions and bipolar disorders have a certain probability of co-occurrence. While the presence of a manic episode has been defined as an exclusion criterion for gambling disorder, no such exclusion has been formulated for Internet addiction.

Methods

A clinical sample of 368 treatment seekers presenting with excessive to addictive Internet use was screened for bipolar spectrum disorders using the Mood Disorder Questionnaire. Psychopathology was assessed by the Symptom Checklist 90R and a clinical interview was administered to screen for comorbid disorders.

Results

Comorbid bipolar disorders were more frequent in patients meeting criteria for Internet addiction (30.9%) than among the excessive users (5.6%). This subgroup showed heightened psychopathological symptoms, including substance use disorders, affective disorders and personality disorders. Further differences were found regarding frequency of Internet use regarding social networking sites and online-pornography.

Discussion

Patients with Internet addiction have a heightened probability for meeting criteria of bipolar disorders. It is not possible to draw conclusions regarding the direction of this association but it is recommended to implement screening for bipolar disorders in patients presenting with Internet addiction.

Conclusion

Similar to gambling disorder, it might prove necessary to subsume bipolar disorders as an exclusion criterion for the future criteria of Internet addiction.

Background and aims

Internet Gaming Disorder (IGD) and other Internet-related disorders (IRDs) have become growing health concerns in our today’s lives. Based on defined diagnostic criteria, IGD has been recognized as a condition for further research in the DSM-5; however, other IRDs have been excluded. Since the release of the DSM-5, representativeness and appropriateness of the nine diagnostic criteria have been debated. Although some first evidence has been published to evaluate these criteria, our knowledge is still limited. Thus, the purpose of this study was to provide data on the clinical validity of the DSM-5 criteria for IGD and other types of IRD. We were also interested in examining the additional diagnostic validity of craving that is currently not being considered in the DSM-5.

Methods

Analyses on a sample of n = 166 treatment seekers for IRDs were performed. The clinician’s diagnosis was used as a main reference for determining the DSM criteria’s diagnostic performance. Secondary criteria (depression and anxiety) were defined as indicators for the construct validity.

Results

The overall diagnostic accuracy ranged between 76.6% for deceiving and 92% for loss of control and craving. Considerable differences occurred in the degree of sensitivity and specificity between the single criteria. No particular differences were found for the applicability of the criteria to other forms of IRDs.

Discussion and conclusions

Our results confirm the validity of the DSM criteria. However, the diagnostic utility of the criterion escaping aversive moods is critically discussed. Considering craving as an additional diagnostic indicator might be recommendable.

Background and aims

Gambling disorder is a significant public health concern. Especially, male minors have been shown to gamble in a problematic way, despite legal prohibitions.

Methods

We examined representative samples of students aged from 12 to 18 years (N = 9,309) in two German federal states to provide prevalence data and clinical description of risk factors for problematic gambling.

Results

We found that about 40% of the adolescents reported engaging in gambling activities within the past 12 months and found prevalence rates of 1.7% and 2.2% for problematic gambling. Especially, use of online gambling and slot machines was found to be related to problematic gambling. Male adolescents with a migration background were of higher risk for problematic gambling and psychopathological symptoms were significantly elevated among that group.

Discussion

The results indicate that participation in gambling activities is common among underaged adolescents and that prevalence of problematic gambling exceeds rates of adults. Similarly, problematic gambling is associated with increased psychopathological strain.

Conclusion

Given that a high proportion of adult gamblers report having started gambling in adolescents, our data emphasize the need for prevention and early intervention strategies for problematic gambling.
