Problems and competencies reported by parents of Vietnamese children in Hanoi.

OBJECTIVE: To determine the distribution of behavioral and emotional problems and competencies among a sample of Vietnamese children aged 4 through 18 years living in Hanoi. METHOD: A representative community sample of 1,526 children and adolescents was selected from 2 precincts in Hanoi. Problems and competencies were assessed with the Child Behavior Checklist (CBCL). RESULTS: Vietnamese children had lower mean raw scores than U.S. norms on the CBCL's Total, Externalizing, Internalizing, and Competence scales. Boys were reported to have more externalizing problems and girls more internalizing problems. Girls' levels of internalizing problems increased significantly with age. CONCLUSION: The lower levels of problems and competencies reported in Vietnamese children may represent differences in the prevalence of psychiatric disorders, in parental perceptions of what constitutes deviant behavior, or in parental comfort with reporting psychopathological behaviors. Further research is needed to clarify the relationship between the reported behavioral and emotional problems of Vietnamese children and the presence of psychiatric disorders. From a clinical perspective, the study's results suggest that levels of problems and competencies may vary significantly between different ethnic and cultural groups. Specific clinical cutoffs used to identify children requiring further psychiatric assessment need to be established separately for different ethnic groups.

Vietnamese parental perceptions of child and adolescent mental illness.

OBJECTIVES: To determine the symptoms and behaviors in children which are considered psychopathological by Vietnamese parents, to identify professionals and agencies in the community whom Vietnamese parents would consult if their child had a mental illness, and to determine Vietnamese parents' awareness of existing community mental health services. METHOD: Structured interviews were conducted with a randomized community sample of 283 Vietnamese parents in Perth, Australia. Parents were asked to identify the symptoms and behaviors they considered psychopathological in children, where they would turn for help with a mentally ill child, their knowledge of community mental health services for children, and their understanding of the causes of child psychiatric disorders. RESULTS: Vietnamese parents identified psychotic symptoms, disorientation, and suicidal thoughts and behavior as psychopathological. They preferentially endorsed Western-style treatment approaches but had little awareness of existing community mental health services for children. A biological/chemical imbalance, traumatic experiences, and a metaphysical/spiritual imbalance were identified as the most likely causes of child mental illness. CONCLUSIONS: Despite a different cultural tradition, Vietnamese parents appear open to services provided by Western-trained mental health professionals. Their very limited awareness of child and adolescent mental health services in the community, however, may severely limit their utilization of such services.

Is there a role for child psychiatry in Vietnam?

OBJECTIVES: (i) To describe the need for child psychiatric services in Vietnam; (ii) to review child psychiatry's present role within the Vietnamese health care system; (iii) to identify cultural, economic and manpower obstacles to the development of child mental health services; and (iv) to recommend a course for the future development of child psychiatry in Vietnam. METHOD: The existing literature relevant to the Vietnamese health and mental health care systems, traditional practices and beliefs regarding health and mental health, and the current status of psychiatry and child psychiatry in Vietnam was reviewed. In addition, discussions regarding these topics, and the future of child psychiatry in Vietnam, were held with leading Vietnamese health and mental health professionals. RESULTS: The current role of child psychiatry in Vietnam is limited by the health care system's focus on infectious diseases and malnutrition, and by cultural, economic and manpower factors. Treatment is reserved for the most severely afflicted, especially patients with epilepsy and mental retardation. Specialised care is available in only a few urban centres. In rural areas treatment is provided by allied health personnel, paraprofessionals and community organisations. CONCLUSIONS: While the present role of child psychiatry in Vietnam is limited, it can still make important contributions. These include: research defining the need for child and adolescent mental health services, identifying priority child psychiatric disorders and assessing the effectiveness of priority disease treatment; and training to enhance the skills of primary health care providers in the treatment of priority disorders.

Visual persistence and code selection in short-term memory for letters.

Four experiments were conducted to examine temporal changes in visual and name codes and the relationship between them. Unlike earlier studies, the design included (a) several levels of visual similarity in addition to the conventional same case and different case conditions and (b) physical- as well as name-match tasks to provide direct evidence about subjects' retention of form information. The main results were as follows: First, the presence of multiple typefonts in the stimulus set does not eliminate convergence between the reaction time functions for the physical- and name-match conditions in a name-match task. Second, inclusion of a physical-match task, requiring subjects to retain form information, does not necessarily eliminate convergence in a primary, name-match task. When the secondary task does reduce convergence, however, the results suggest that it does this through its effect on the name-match function rather than on the physical-match function. Third, apart from difficulties with within-cluster typefont combinations, particularly at long interstimulus intervals, subjects can generally retain and use reliable information about letter form over the ISI range (.5--4.0 sec) used in the experiments. The results were thought to be consistent with the conclusion that convergence results from a combination of (a) a nonoptional decrease in the accessibility of the visual code as a function of increasing ISI and (b) an optional increase in the accessibility of the name code. Under ISI conditions at least, convergence cannot be attributed to either generation of a visual code of the alternative form of the target letter or to the absence of relevant form information.
