Early and middle childhood developmental,cognitive, and psychiatric outcomes of Malawian children affected by retinopathy positive cerebral malaria

The objective is to determine the short -and long-term developmental, cognitive, and psychiatric effects of retinopathy positive cerebral malaria (CM-R) among young children in a prospective study assessing them around the onset of disease and again 2 years at preschool and again at school age.

In total, 109 children were recruited from the Queen Elizabeth Central Hospital in Blantyre, Malawi, (N = 49) with CM-R and non-malaria controls (N = 60). Children were assessed for overall motor, language, and social skills using the Malawi Developmental Assessment Tool (MDAT) at preschool age. At school age, the same children were then given the Kaufman Assessment Battery for Children, second edition (KABC-II), which assessed global cognitive performancememory, and learning; as well as the Test of Variables of Attention (TOVA), which assessed attention. The Achenbach Child Development Checklist (CBCL) was administered at both time points to assess emotional and behavioral patterns.

Controls scored significantly better on all KABC-II global domains as well as on the mental processing index than their CM-R group counterparts, but showed no performance differences in the TOVA and CBCL assessments at school age, or in the MDAT and CBCL assessments at preschool age. The MDAT total score was significantly correlated with the KABC-II sequential processing, learning, and mental processing index among CM-R survivors but not among controls.

Persisting neurocognitive effects of CM can be captured with the KABC-II at school age. The MDAT at preschool age is correlated with the KABC-II among CM-R survivors and can be used to capture early emerging developmental deficits due to CM-R.     

Personnel selection in the digital age: a review of validity and applicant reactions,and future research challenges

ABSTRACT

We present a targeted review of recent developments and advances in digital selection procedures (DSPs) with particular attention to advances in internet-based techniques. By reviewing the emergence of DSPs in selection research and practice, we highlight five main categories of methods (online applications, online psychometric testing, digital interviews, gamified assessment and social media). We discuss the evidence base for each of these DSP groups, focusing on construct and criterion validity, and applicant reactions to their use in organizations. Based on the findings of our review, we present a critique of the evidence base for DSPs in industrial, work and organizational psychology and set out an agenda for advancing research. We identify pressing gaps in our understanding of DSPs, and ten key questions to be answered. Given that DSPs are likely to depart further from traditional non-digital selection procedures in the future, a theme in this agenda is the need to establish a distinct and specific literature on DSPs, and to do so at a pace that reflects the speed of the underlying technological advancement. In concluding, we, therefore, issue a call to action for selection researchers in work and organizational psychology to commence a new and rigorous multidisciplinary programme of scientific study of DSPs.     

Psychometric properties of the Turkish version of the Flourishing Scale and the Scale of Positive and Negative Experience

ABSTRACT

The Flourishing Scale (FS) and the Scale of Positive and Negative Experience (SPANE) are scales that are newly introduced to evaluate well–being. The present study aims to assess the psychometric distinctive features of two scales by utilising two different Turkish samples: university students (n?=?320), and employees (n?=?180). Confirmatory factor analysis results demonstrate that a one-factor model of the FS and a two–factor model of the SPANE yield significant findings in those samples. Scales’ factorial structures are valid for gender groups also they have good internal consistency. Concurrent validity, and discriminant validity with the use of several conceptually related and unrelated measures in two samples reveal satisfactory validity results for both the FS and the SPANE. The results of the present study show the utility of these scales in Turkish culture.     

Factorial validity of the Utrecht Work Engagement Scale (UWES) across occupational groups in Norway

Nerstad, C.G.L., Richardsen, A.M. & Martinussen, M. (2009). Factorial validity of the Utrecht Work Engagement Scale (UWES) across occupational groups in Norway. Scandinavian Journal of Psychology. The present study investigated the factorial validity of the Utrecht Work Engagement Scale (UWES) among 1266 participants from ten different occupational groups. Confirmatory factor analyses of the total sample, as well as multi‐group analyses and analyses of each of the ten occupational groups separately, indicated that a three‐dimensional model of both the UWES‐17 and the short version, UWES‐9, provided a better fit to the data than a one‐ and two‐dimensional model. The results of multi‐group analyses and analyses of each of the groups separately, indicated that with a few exceptions, the three‐factor model of work engagement provided the best fit. Results indicated factorial invariance and the internal consistencies were acceptable. The fit of the UWES‐9 was slightly better than the UWES‐17. It is concluded that the Norwegian short version may be recommended over the UWES‐17.     

Quantifying definitional relations in psychological measurement

Quantitative inferences about psychological attributes, such as extraversion, depression and empathy, involve measurement instruments as well as mathematical models that specify how indicators should be aggregated. The type of model that is appropriate for doing so is conditional on the type of relation that exists between an attribute, its facets and its indicators. The common assumption is that such relations are causal relations. Here, instead, we address definitional attribute-facet relations. Our aim is to find an appropriate mathematical model for when an attribute is defined in terms of facets, instead of causing or being caused by facets. In doing so, we describe the semantics of definitions in logical form. From this form we then derive continuous functions for attribute-facet relations using fuzzy logic. A model with main effects and interactions between facets seems to be more powerful for representing definitional relations than traditional formative and reflective models. This has important implications for measurement in basic and applied research.     

Do overall dimension ratings from assessment centres show external construct-related validity?

ABSTRACT

There have been repeated calls for an external construct validation approach to advance our understanding of the construct-related validity of assessment centre dimension ratings beyond existing internal construct-related validity findings. Following an external construct validation approach, we examined whether linking assessment centre overall dimension ratings to ratings of the same dimensions that stem from sources external to the assessment centre provides evidence for construct-related validity of assessment centre ratings. We used data from one laboratory assessment centre sample and two field samples. External ratings of the same dimensions stemmed from assessees, assessees’ supervisors, and customers. Results converged across all three samples and showed that different dimension-same source correlations within the assessment centres were larger than same dimension-different source correlations. Moreover, confirmatory factor analyses revealed source factors but no dimension factors in the latent factor structure of overall dimension ratings from the assessment centre and from external sources. Hence, consistent results across the three samples provide no support that assessment centre overall dimension ratings and ratings of the same dimensions from other sources can be attributed to dimension factors. This questions arguments that assessment centre overall dimension ratings should have construct-related validity.
