To cite this version:Alexandra Rouquette, Bruno Falissard. Sample size requirements for the internal validation of psychiatric scales.. International Journal of Methods in Psychiatric Research, Wiley, 2011, 20 (4) Abstract:The ratio of subjects to variables (N/p), as a rule to calculate the sample size required in internal validity studies on measurement scales, has been recommended without any strict theoretical or empirical basis being provided. The purpose of the present study was to develop a tool to determine sample size for these studies in the field of psychiatry. First, a literature review was carried out to identify the distinctive features of psychiatric scales. Then, two simulation methods were developed to generate data according to: 1/ the model for factor structure derived from the literature review and 2/ a real dataset. This enabled the study of the quality of solutions obtained from principal component analysis or Exploratory Factor Analysis (EFA) on various sample sizes. Lastly, the influence of sample size on the precision of Cronbach"s alpha coefficient was examined. The N/p ratio rule is not upheld by this study: short scales do not allow smaller sample size. As a rule of thumb, if one"s aim is to reveal the factor structure, a minimum of 300 subjects is generally acceptable but should be increased when the number of factors within the scale is large, when EFA is used and when the number of items is small.

“…The western definition of psychiatric disorders, with its emphasis on biological factors, may increase the rate of somatoform disorders in communities with culturally different symptoms 19 , particularly among Asians 20 , who show more physical complaints than psychological symptoms 21,22 . However, a higher frequency of somatoform disorders among immigrant Koreans than among non-immigrant Koreans (7.4% vs. 0.6%) raises questions about the role of immigration on the onset of this psychiatric disorder.…”

“…The comparison with Chinese-Americans revealed a similar rate of depressive episodes (6.2% vs. 6.9%), but a lower rate of dysthymia (2.5% vs. 5.2%) 24 . Surveys show that Asians have lower rates of mood disorders than Western people because they rarely report psychological complaints 21,22,24 . However, even considering this culturally different psychopathological pattern among Asians, Korean immigrants have more depressive disorders (8.3%, depressive episode/dysthymia) than other Asian communities in Brazil: Japanese-Brazilians (3.2%; using the Self Reported Questionnaire -SRQ-20) 3 and Chinese-Brazilians (4.8%; using the Beck Depression Inventory) 22 .…”

Although rates obtained by using different instruments are not easily compared, the higher rates of mood disorders among subjects from this study, compared with the population of their native country and other Asian communities in Brazil, may indicate a higher vulnerability to mood disorders among this community.…”

This study investigated the frequency of lifetime mental disorders among Korean immigrants in the city of São Paulo, Brazil. Snowball sampling with multiple focuses was used to recruit Korean immigrants older than 18 years and living in São Paulo. A total of 324 Korean immigrants were selected and their mental status was evaluated using a structured interview, namely the Portuguese or the Korean version of the Composite International Diagnostic Interview 2.1. The diagnoses of mental disorders were made according to the ICD-10. The frequency of any lifetime psychiatric disorder was 41.9%. The frequencies of main disorders were: anxiety disorder, 13% (post-traumatic stress disorder, 9.6%); mood disorder, 8.6%; somatoform disorders, 7.4%; dissociative disorder, 4.9%; psychotic disorder, 4.3%; eating disorder, 0.6%; any substance (tobacco, alcohol, drugs) use disorder, 23.1%. The frequency of any psychiatric disorder except alcohol and tobacco use disorders was 26.2%. Korean immigrants have more psychiatric disorders than the Korean population in Korea, particularly post-traumatic stress disorder, and almost the same rate as the Brazilian population. Mental health authorities should promote a healthier integration and the development of culturally sensitive mental health programs for Korean immigrants.
