Compulsive Internet Use Scale for assessment of self-reported problematic internet use in primary school-aged children.

Introduction: The tremendous growth of internet use during past few decades has been primarily led by young people. Despite a plenitude of studies reporting the pros and cons of excessive internet use by adolescents, the internet use of primary school-aged children is under-researched. First, there is lack of reliable and valid cultural invariant self-report instruments for children younger than 11-years-old.

Cultural contributions to adults' self-rated mental health problems and strengths: 7 culture clusters, 28 societies, 16 906 adults.

Background: It is unknown how much variation in adult mental health problems is associated with differences between societal/cultural groups, over and above differences between individuals.

Methods: To test these relative contributions, a consortium of indigenous researchers collected Adult Self-Report (ASR) ratings from 16 906 18- to 59-year-olds in 28 societies that represented seven culture clusters identified in the Global Leadership and Organizational Behavioral Effectiveness study (e.g.

Children's Internet Use Profiles in Relation to Behavioral Problems in Lithuania, Latvia, and Taiwan.

This study explored the profiles of elementary-school-aged children's Internet use in relation to their emotional and behavioral problems. Participating in this cross-sectional study were 877 child-parent dyads from Latvia, Lithuania, and Taiwan. Children (8-10 years old) provided information on three variables: the amount of time they spent online, frequency of online activities, and knowledge of how to do things online.

Older adult psychopathology: international comparisons of self-reports, collateral reports, and cross-informant agreement.

Objectives: To conduct international comparisons of self-reports, collateral reports, and cross-informant agreement regarding older adult psychopathology.

Participants: We compared self-ratings of problems (e.g.

The generalizability of Older Adult Self-Report (OASR) syndromes of psychopathology across 20 societies.

Objectives: As the world population ages, psychiatrists will increasingly need instruments for measuring constructs of psychopathology that are generalizable to diverse elders. The study tested whether syndromes of co-occurring problems derived from self-ratings of psychopathology by US elders would fit self-ratings by elders in 19 other societies.

Methods/design: The Older Adult Self-Report (OASR) was completed by 12 826 adults who were 60 to 102 years old in 19 societies from North and South America, Asia, and Eastern, Northern, Southern, and Western Europe, plus the United States.

Syndromes of Self-Reported Psychopathology for Ages 18-59 in 29 Societies.

This study tested the multi-society generalizability of an eight-syndrome assessment model derived from factor analyses of American adults' self-ratings of 120 behavioral, emotional, and social problems. The Adult Self-Report (ASR; Achenbach and Rescorla 2003) was completed by 17,152 18-59-year-olds in 29 societies. Confirmatory factor analyses tested the fit of self-ratings in each sample to the eight-syndrome model.

Cross-cultural comparisons of child-reported emotional and physical abuse: rates, risk factors and psychosocial symptoms.

Objectives: This study was designed to assess the incidence of child emotional and physical abuse, associated risk factors and psychosocial symptoms in a cross-cultural comparison between post-communist bloc countries.

Method: One-thousand one-hundred forty-five children ages 10-14 from Latvia (N = 297), Lithuania ( N = 300), Macedonia (N = 302), and Moldova (N = 246) participated in the study. They completed questionnaires assessing their experience of emotional or physical abuse, and provided information about family risk-factors and psychosocial symptoms, including PTSD-related symptoms.
