The aim of this study was to determine the prevalence of cyberstalking victimization, characteristics of victims and offenders, and the impact of cyberstalking on the victims' well-being and mental health. An online survey of 6,379 participants was carried out, involving users of the German social network StudiVZ. Subjective mental health status was assessed with the WHO-5 well-being index. The prevalence of cyberstalking was estimated at 6.3%. In various aspects, cyberstalking was comparable to offline stalking: cyberstalking occurred most often in the context of ex-partner relationships; most of the victims were female and the majority of the perpetrators were male. Compared to non-victims, victims of cyberstalking scored significantly poorer on the WHO-5 well-being index. The prevalence of cyberstalking is considerable. However, if stringent definition criteria comparable to those of offline stalking are applied, it is not a mass phenomenon. The negative impact of cyberstalking on the victims' well-being appears similar to that of offline stalking. Hence, cyberstalking should be taken as seriously as offline variants of stalking by legal authorities and victim assistance professionals.

The similarity of IEI and SFD regarding symptoms and psychological features of somatization support the hypothesis that IEI is a variant of SFD.

Idiopathic environmental intolerance (IEI) refers to a polysymptomatic condition, similar to somatoform disorders. Various processes seem to contribute to its yet unknown etiology. Attention and memory for somatic symptom and IEI-trigger words was compared among participants with IEI (n = 54), somatoform disorders (SFD; n = 44) and control participants (n = 54). Groups did not differ in a dot-probe task. However, in an emotional Stroop task, attention was biased in IEI and SFD groups toward symptom words but not toward IEI-trigger words. Only the IEI group rated trigger words as more unpleasant and more arousing, and participants remembered them better in a recognition task. These implicit and explicit cognitive abnormalities in IEI and SFD may maintain processes of somatosensory amplification.

The present prospective follow-up study of 163 schizophrenic patients admitted to hospital for the first time examined the relationship between premorbid adjustment and different measures of the 3-year course and outcome. The same instruments had been used in all phases of the study. The Premorbid Adjustment Scale was used to assess premorbid social functioning. Outcome measures were positive symptoms, negative symptoms, social disability and number of rehospitalizations. The results of the multiple regression analyses showed that premorbid adjustment was the strongest overall predictor of outcome. Premorbid adjustment was significantly associated with negative symptoms and social disability over the 3-year course of illness. In a further step, we examined the relationship between good, moderate and poor premorbid adjustment and the course of positive symptoms, negative symptoms and social disability within the first 3 years after index admission. The most important finding was that premorbid functioning showed a stronger correlation with the course of negative symptoms and social disability than with the course of positive symptoms. Poor premorbid social functioning implies a poor social course of the illness. Female subjects showed better premorbid functioning than male subjects. Good premorbid adjustment was strongly associated with an acute onset of the illness, and poor premorbid adjustment with an insidious onset.

These results do not support the proposed splitting of health anxiety/hypochondriasis into two diagnoses. Further validation studies with larger samples and additional control groups are warranted to prove the validity of the new diagnoses.

IEI and SFD are highly stable conditions. In both SFD and IEI, NA and the processes of symptom perception, interpretation and attribution contribute substantially to the persistence of typically somatoform symptoms and IEI complaints. Treatment of IEI and SFD should address these psychological factors and mechanisms.
