Goldberg’s (2006) bass-ackwards approach to elucidating the hierarchical structure of individual differences data has been used widely to improve our understanding of the relationships among constructs of varying levels of granularity. The traditional approach has been to extract a single component on the first level of the hierarchy, two components on the second level, and so on, treating the correlations between the components on adjoining levels akin to path coefficients in a hierarchical structure. This article proposes three modifications to the current approach with a particular focus on examining associations among all levels of the hierarchy: 1) identify and remove redundant components that perpetuate through multiple levels of the hierarchy; 2) (optionally) identify and remove artefactual components; and 3) plot the strongest component correlations among the remaining components to identify their hierarchical associations. Together these steps can offer a simpler and more complete picture of the underlying hierarchical structure among a set of observed variables. The rationale for each step is described, illustrated in a hypothetical example, and then applied in real data with specific methodological recommendations. The results are compared to the traditional bass-ackwards approach, and basic code is provided to apply the proposed modifications in other data.

Objective: To examine the extent to which neuroscience accounts for mental disorders. Method: Relevant literature on this problem was selectively reviewed. Results: Thus far, neuroscience research has contributed more to the understanding of the brain than to determining the causes of mental disorders. Its model is more appropriate to severe than to common mental disorders. A reductionistic approach cannot account for emergent phenomena occurring at the level of the mind. Conclusions: Mental disorders cannot be reduced to abnormalities in neuronal activity; psychiatric symptoms need to be understood at multiple levels.

SummaryThe paper presents an overview of the WHO World Mental Health (WMH) Survey Initiative and summarizes recent WMH results regarding the prevalence and societal costs of mental disorders. The WMH surveys are representative community surveys that were carried out in 28 countries throughout the world aimed at providing information to mental health policy makers about the prevalence, burden, and unmet need for treatment of common mental disorders. Results show that mental disorders are commonly occurring in all participating countries. The inter-quartile range (IQR: 25th-75th percentiles) of lifetime DSM-IV disorder prevalence estimates (combining anxiety, mood, disruptive behavior, and substance disorders) is 18.1-36.1%. The IQR of 12-month prevalence estimates is 9.8-19.1%. Analysis of age-of-onset reports shows that many mental disorders begin in childhood-adolescence and have significant adverse effects on subsequent role transitions. Adult mental disorders are found in the WMH data to be associated with high levels of role impairment. Despite this burden, the majority of mental disorders go untreated. Although these results suggest that expansion of treatment could be cost-effective from both the employer perspective and the societal perspective, treatment effectiveness trials are needed to confirm this suspicion. The WMH results regarding impairments are being used to target several such interventions.

AbstractThe following paper depicts the history of Saint Simeon Stylites Uniate Parish in Rachanie since it became known in historical sources until 1811- that is the time it ceased to be an independent church unit. The introduction of the article contains the geographical location of the parish, its size and the position within the hierarchical structure of the Church. Having analysed post-visit inspection protocols left by Chelm Bishops, the appearance as well as fittings and ancillary equipment of the church in Rachanie in that particular period are reported. Moreover, the list of 4 local clergymen is recreated and their benefice is determined. As far as possible, both the number of worshipers and the number of Holy Communion receivers is determined.

Aims: To explore associations between experiences of mental illness, migration status and languages spoken among Pacific adults living in NZ. Methods: SURVEY FREQ and SURVEY LOGISTIC procedures in SAS were applied to data from Te Rau Hinengaro: The New Zealand (NZ) Mental Health Survey, a survey of 12,992 New Zealand adults aged 16 and over in 2003/2004. Pacific people were over sampled and this paper focuses on the 2374 Pacific participants but includes, for comparison, 8160 non-Maori-non-Pacific (NMNP) participants. Results: Pacific migrant respondents had the lowest prevalence of mental disorders compared to other Pacific peoples. However, Pacific immigrants were also less likely to use mental health services, suggesting an increased likelihood of experiencing barriers to available mental health care. Those who were born in NZ and who were proficient in a Pacific language had the lowest levels of common mental disorders, suggesting a protective effect for the NZ-born population. Additionally, access to mental health services was similar between NZ-born people who spoke a Pacific language and those who did not. Conclusions: We conclude that, given the association between Pacific language and reduced mental disorder, there may be a positive role for Pacific language promotion in efforts to reduce the prevalence of mental health disorder among Pacific communities in NZ.
