Decreased Occupational Functioning and Increased Physical Health Complaints in Treatment Seekers with Internet-Related Disorders: Compared to Patients with Gambling Disorder.

BACKGROUND

Internet-related disorders (IRDs) as a growing mental health issue will probably be included in the upcoming ICD-11. While research on psychological aspects has progressed, less data are available regarding the physical health status of patients. Thus, we provide new data on physical health complaints, prediagnosed illness, level of functioning, and work ability in a clinical sample.

METHODS

From consecutive treatment seekers, we included n = 286 patients with IRD, n = 95 subjects with excessive yet not disordered Internet use, and n = 106 patients with gambling disorder (GD). All 3 groups were compared regarding lifestyle habits, medical history, somatic complaints, sleep disturbances, level of functioning and work ability using standardized self-reports, and clinical ratings.

RESULTS

Patients with IRD differed from nonclinical controls by higher somatic complaints, a lower level of functioning, and a higher degree of impairment in social and occupational contexts. Only few differences were found between patients with IRD and GD.

CONCLUSIONS

Compared to individuals with excessive, not addictive online behaviors, patients diagnosed with IRD displayed higher somatic symptoms, and more sleep problems. This implies that psychotherapeutic interventions should also consider physical and psychosomatic problems when treating patients. Among patients with IRD, significant social and occupational deficits were comparable to patients with GD. This emphasizes that IRD are causing severe impairment in relevant aspects of the patients' lives.
