Abstract: Peer assessment has been the subject of considerable research interest over the last three decades, with numerous educational researchers advocating for the integration of peer assessment into schools and instructional practice. Research synthesis in this area has, however, largely relied on narrative reviews to evaluate the efficacy of peer assessment. Here, we present a meta-analysis (54 studies, k = 141) of experimental and quasi-experimental studies that evaluated the effect of peer assessment on academic performance in primary, secondary, or tertiary students across subjects and domains. An overall small to medium effect of peer assessment on academic performance was found ( g = 0.31, p .001). The results suggest that peer assessment improves academic performance compared with no assessment ( g = 0.31, p = .004) and teacher assessment ( g = 0.28, p = .007), but was not significantly different in its effect from self-assessment ( g = 0.23, p = .209). Additionally, meta-regressions examined the moderating effects of several feedback and educational characteristics (e.g., online vs offline, frequency, education level). Results suggested that the effectiveness of peer assessment was remarkably robust across a wide range of contexts. These findings provide support for peer assessment as a formative practice and suggest several implications for the implementation of peer assessment into the classroom.

Abstract: Social suffering, language difficulties, and cultural factors may all make the cancer experience more difficult for immigrants. This study aimed to document unmet needs, and variables associated with these, in a population-based s le of first-generation immigrants and Anglo-Australians who had survived cancer. Participants were recruited via Australian cancer registries. Eligible cancer survivors had a new diagnosis 1-6 years earlier and were aged between 18 and 80 years at diagnosis. Eligible immigrant participants and parents were born in a country where Arabic, Chinese (Mandarin, Cantonese, and other dialects), or Greek is spoken, and they spoke one of these languages. A random s le of English-speaking Anglo-Australian-born controls was recruited. Five hundred ninety-six patients (277 immigrants) were recruited to the study (response rate, 26%). Compared to Anglo-Australians, the adjusted odds ratio of Chinese immigrants for at least one unmet information/support need was 5.1 (95% CI 3.1, 8.3) and for any unmet physical need was 3.1 (95% CI 1.9, 5.1). For Greek, these were 2.0 (95% CI 1.1, 4.0) and 2.7 (95% CI 1.4, 5.2). Arabic patients had elevated, but not statistically significant, odds ratios compared to Anglo-Australians. Written information and having a specialist, support services, and other health professionals who spoke their language were in the top ten unmet needs amongst immigrants. Immigrant cancer survivors, several years after initial diagnosis, are more likely to have an unmet need for information or for help with a physical problem than Anglo-Australians. They strongly desire information and support in their own language.

Abstract: The purpose of this study was to assess the invariance of a culturally competent multi-lingual unmet needs survey. A cross-sectional study was conducted among immigrants of Arabic-, Chinese- and Greek-speaking backgrounds, and Anglo-Australian-born controls, recruited through Cancer Registries (n = 591) and oncology clinics (n = 900). The survey included four subscales, with newly developed items addressing unmet need in culturally competent health information and patient support (CCHIPS), and items adapted from existing questionnaires addressing physical and daily living (PDL), sexuality (SEX) and survivorship (SURV) unmet need. The survey was translated into Arabic, Chinese and Greek. Rasch analysis was carried out on the four domains. Whilst many items were mistargeted to less prevalent areas of unmet need, causing substantial floor effects in person estimates, reliability indices were acceptable. The CCHIPS domain showed differential item functioning (DIF) for cultural background and language, and the PDL domain showed DIF for treatment phase and gender. The results for SEX and SURV domains were limited by floor effects and missing responses. All domains showed adequate fit to the model after DIF was resolved and a small number of items were deleted. The study highlights the intricacies in designing a culturally competent survey that can be applied to culturally and linguistically erse groups across different treatment contexts. Overall, the results demonstrate that this survey is somewhat invariant with respect to these factors. Future refinements are suggested to enhance the survey's cultural competence and general validity.

Abstract: 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 s le 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. Eligible participants, recruited via 16 oncology clinics in Australia, included those over the age of 18, diagnosed with cancer (any type or stage) within the previous 12 months and having commenced treatment at least 1 month previously. In total, 571 migrant patients (comprising 145 Arabic, 248 Chinese, and 178 Greek) and a control group of 274 Anglo-Australian patients participated. In multiple linear regression models adjusted for age, sex, education, marital status, socioeconomic status, time since diagnosis, and type of cancer, migrants had clinically significantly worse health-related quality of life (HRQL 3.6–7.3 points on FACT-G, p & .0001), higher depression and anxiety (both p & .0001), and higher incidence of clinical depression (p & .0001) and anxiety (p = .003) than Anglo-Australians. Understanding the health system (p & .0001 for each outcome) and difficulty communicating with the doctor (p = .04 to .0001) partially mediated the impact of migrancy. In migrant-only analyses, migrant-related variables (language difficulty and poor understanding of the health system), not ethnicity, predicted outcomes. Migrants who develop cancer have worse psychological and HRQL outcomes than Anglo-Australians. Potential targets for intervention include assistance in navigating the health system, translated information, and cultural competency training for health professionals.

Abstract: 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. Without being demonstrated, we think the premise is potentially misleading.

Abstract: Health-related quality of life (HRQoL) and unmet needs (needs) questionnaires offer alternative perspectives for assessing cancer patients' concerns. We examined whether the conceptual differences underlying these alternative approaches yield corresponding empirical differences. Eight-hundred and seventy-four women with ovarian cancer completed the Functional Assessment of Cancer Therapy scale (FACT-G HRQoL) and the Supportive Care Needs Survey (SCNS-SF34 needs) every 3 months for 2 years. Correlational analysis, exploratory and confirmatory factor analysis (EFA/CFA), and Rasch analysis tested the relationship between patients' responses to similar domains and similar items across the two questionnaires. Strong correlations were found between items with virtually identical wording (0.67-0.75), while moderate to strong correlations (0.55-0.65) were found for those with very similar wording. EFA identified two common domains across the two questionnaires: physical and psychological. For each common domain, CFA indicated models involving a single construct with systematic variation within each questionnaire fit best. Rasch analysis including very similar items within the physical and psychological domains (separately) demonstrated strong evidence of unidimensionality. The high degree of similarity between patient responses to items addressing the same or very similar concerns suggests either that HRQoL and needs approaches do not reflect different constructs or that patients may not be able to differentiate between the severity of a concern and the level of need associated with that concern, especially when these are assessed in quick succession.

Abstract: This study compared health-related quality of life (QOL) and psychological morbidity in a population-based s le 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 s le of English-speaking Anglo-Australian-born controls frequency matched for cancer diagnosis was recruited. 596 patients (277 of whom were immigrants) participated (a 26% response rate). In multiple linear regression models adjusted for age, sex, education, marital status, socio-economic status, time since diagnosis and type of cancer, immigrants had clinically significantly worse QOL (5.4-8.5 points on Functional Assessment of Cancer Therapy - General (FACT-G), P<0·0001), higher depression (P<0·0001) and higher incidence of clinical depression (P<0·01) than Anglo-Australians. Understanding the health system partially mediated this relationship for depression (P=0·0004) and QOL (P=0·001). Immigrant survivors of cancer have worse psychological and QOL outcomes than Anglo-Australians. Potential targets for intervention include assistance in navigating the health system, translated information and cultural competency training for health professionals.

Abstract: 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. The results were consistent with a bipolar interpretation, providing support for the argument that ambivalent evaluations are the correct middle-point of a bipolar evaluative dimension. Thus, it is argued that attitudinal ambivalence does not necessitate moving beyond bipolarity, but rather, moving beyond the conventional conceptualization and assessment of attitudes.
