McNair Post-Baccalaureate Achievement Program provides higher education institutions with federal funds to increase the doctoral attainment for students from disadvantaged backgrounds. We conducted a meta-analysis of the impact of the McNair program on graduate program enrollment. After an exhaustive literature search, we found 7 publications containing 13 studies that met the inclusion criteria. From these studies, we found that McNair program students were almost six times as likely to enroll in a graduate program as the comparison group. Nonetheless, there was much unexplained variability in effects across studies.

To date, very little has been published on the properties of this subtest’s items and scores. The BP test is similar in design to the Block Design subtest found in many cognitive ability assessments but uses a matching format that minimizes the need for excess materials and time. We analyzed the BP items using item response theory (IRT) methods. Although designed to measure a single construct, the analyses from this study found that the BP subtest is likely measuring more than a single construct, which confounds the interpretation of the instrument’s scores. Before the subtest is used clinically, more research should be done to purposefully investigate the effects of ancillary variables on its scores.

Configural, metric, and scalar invariance were found. However, the error variance of the Coding subtest was not constant across time, allowing only partial strict invariance. This indicates that the WISC-IV (a) was measuring similar constructs at both test occasions, (b) constructs had the same meaning across time, (c) scores that changed across time can be attributed to change in the constructs being measured and not to changes in the structure of the test itself, and (d) measures the same constructs equally well across time with the possible exception of Processing Speed due to the noninvariance of the Coding subtest’s residual variance. This investigation provided support for intelligence as an enduring trait and for the validity of the WISC-IV.

A few studies have demonstrated counter-intuitive findings known as reverse epidemiology where normal levels of cholesterol are associated with higher levels of mortality. The purpose of this study was to determine if there are reverse epidemiological associations between lipid risk factors and mortality in ESRD patients. Methods: ESRD (n = 438) patients were recruited from 4 outpatient dialysis units. Patients were tracked for 36 months until study completion or death with mortality status as the outcome measure. Results: Analysis of covariance revealed significant differences at posttest and reverse epidemiological effects for total cholesterol (p = 0.0001), low-density lipoprotein cholesterol (LDL) (p = 0.023), LDL particle number (p = 0.0001), LDL size (p = 0.009), triglycerides (p = 0.0001), and very low-density lipo...

In this study, the authors examined the reliability and structural validity of the NEO-FFI scores at the item level in a large sample of Jamaican young adults ( N = 1,021; ages 17-24 years). Across different factor estimation and rotation methods, many NEO-FFI items performed poorly. Likewise, the estimated reliability of the NEO-FFI scores was poor (except Conscientiousness) across different estimations of reliability. These items and scores were then compared with other studies of the NEO-FFI that reported item-level pattern/structure coefficients or reliability estimates. Similarities in item performance and low reliability estimates across studies suggest that the items, rather than cultural differences, account for much of the poor performance of the NEO-FF...
