The popularity of using the Internet and related applications has grown in European countries in the last two decades. Despite numerous advantages in terms of optimizing communications among individuals and social systems, the use of the Internet may be associated with excessive use and possible Internet addiction. The goals of the current study were to validate a French version of the compulsive Internet use scale (CIUS) and to assess its links with common psychiatric symptoms such as depression (assessed with the Beck depression inventory: BDI), anxiety (assessed with the trait anxiety inventory: STAI) and alcohol misuse (assessed with the alcohol use disorder identification test: AUDIT). The French versions of the CIUS, BDI, STAI and AUDIT were administered to a sample of Internet users. Exploratory and confirmatory analyses, correlation analysis and logistic regression were performed. As previously found with the original version, a one-factor model of the CIUS had good psychometric properties and fit the data well. Excessive use of the Internet was associated with depressive symptoms. [less ▲]

Obesity and binge eating disorder are common in individuals with psychotic disorders. Eating and weight-related cognitions are known to influence eating behaviors. The study was designed to assess the psychometric properties of the Mizes Anorectic Cognitions Questionnaire (MAC-R) in patients with psychotic disorders. Binge eating disorder (BED), body mass index (BMI), the MAC-R and the three factor eating questionnaire (TFEQ) were assessed in 125 patients with a diagnosis of schizophrenia or schizoaffective disorder. Whereas the MAC-R has not acceptable psychometric properties, a brief version of the MAC-R (BMAC) has good psychometrical properties and is correlated with TFEQ and BMI. Binge eating disorder is also correlated to the Rigid Weight Regulation and Fear of Weight Gain subscale. The BMAC is a useful brief measure to assess eating and weight related cognitions in people with psychotic disorders. [less ▲]

AIMS: To investigate the beliefs and attitudes of Swiss general psychiatrists toward Internet addiction. METHODS: Ninety-fourth Swiss psychiatrists filled out a questionnaire at a conference of general psychiatry assessing their views on the concept of Internet addiction, their evaluation methods and treatment procedures they use. RESULTS: A cluster analysis revealed three groups: DISBELIEVERS (N = 20) rejected the concept of Internet addiction and its importance, not considering it a real clinical problem and consequently not considering the existence of a specific treatment. The NOSOLOGY BELIEVERS (N = 66) and NOSOLOGY/TREATMENT BELIEVERS (N = 8) assumed that Internet addiction is a real problem. While NOSOLOGY/TREATMENT BELIEVERS asserted the availability of effective treatment (mainly psychological), NOSOLOGY BELIEVERS were less affirmative regarding treatment. CONCLUSION: Thought the concept of Internet addiction is largely acknowledged as a clinical reality by Swiss psychiatrists, routine screening and treatment remain uncommon, mainly due to the belief that efficient treatment is still lacking.
