LanguageScreen: The Development, Validation, and Standardization of an Automated Language Assessment App.

Purpose: Oral language skills provide a critical foundation for formal education and especially for the development of children's literacy (reading and spelling) skills. It is therefore important for teachers to be able to assess children's language skills, especially if they are concerned about their learning. We report the development and standardization of a mobile app-LanguageScreen-that can be used by education professionals to assess children's language ability.

The Bipolarity of Attitudes: Unfolding the Implications of Ambivalence.

Recently, some attitude researchers have argued that the traditional bipolar model of attitudes should be replaced, claiming that a bivariate model is superior in several ways, foremost of which is its ability to account for ambivalent attitudes. This study argues that ambivalence is not at odds with bipolarity per se, but rather the conventional view of bipolarity, and that the psychometric evidence supporting a bivariate interpretation has been flawed. To demonstrate this, a scale developed out of the bivariate approach was examined using a unidimensional unfolding item response theory model: general hyperbolic cosine model for polytomous responses.

Migrant health in cancer: outcome disparities and the determinant role of migrant-specific variables.

Background: Multiethnic societies face challenges in delivering evidence-based culturally competent health care. This study compared health-related quality of life and psychological morbidity in a hospital-based sample of first-generation migrants and Australian-born Anglo cancer patients, controlling for potential confounders related to migrant status. Further, it explored the relative contribution of ethnicity versus migrant-related variables.

Inferior health-related quality of life and psychological well-being in immigrant cancer survivors: a population-based study.

This study compared health-related quality of life (QOL) and psychological morbidity in a population-based sample of first generation immigrant and Anglo-Australian cancer survivors. Eligible participants, recruited via three State Cancer Registries, included those: with a new diagnosis of one of 12 most incident cancers (all stages) 1-6years earlier; aged 18-80 at diagnosis; born in a Chinese, Arabic, or Greek speaking country and able to speak one of these languages. A random sample of English-speaking Anglo-Australian-born controls frequency matched for cancer diagnosis was recruited.

Psychological morbidity and quality of life of ethnic minority patients with cancer: a systematic review and meta-analysis.

Background: Ethnic minority is associated with higher cancer incidence and poorer survival than is being in the majority group. We did a systematic review and meta-analysis to assess whether psychological morbidity and health-related quality of life (HRQoL) were affected by minority status.

Methods: We searched Medline, AMED, PsycINFO, Embase, CENTRAL, CINAHL, PubMed, Sociological Abstracts, and Web of Science for English-language articles published between Jan 1, 1995, and October, 2009.

Is there a contradiction between the network and latent variable perspectives?

First, we question whether Cramer et al.'s proposed network model can provide a viable scientific foundation for investigating comorbidity without invoking latent variables in some form. Second, the authors' claim that the network perspective is radically different from a latent variable perspective rests upon an undemonstrated premise.
