The moderating influence of procedural fairness on the relationship between work-life conflict and organizational commitment

To help employees better manage work-life conflict, organizations have introduced various initiatives, which have met with mixed results. The present studies examined the utility of a procedurally based approach to understanding employees' reactions to work-life conflict. The authors examined whether the fairness of procedures used by organizational authorities to plan and implement decisions moderates the (inverse) relationship between work-life conflict and employees' organizational commitment. Three studies using different methodologies showed support for the moderating role played by procedural fairness. That is, the tendency for greater work-life conflict to lead to lower commitment was significantly less pronounced when procedural fairness was high rather than low. Theoretical contributions to the work-life conflict and organizational justice literatures are discussed, as are practical implications.     

Aging holocaust survivors' well-being and adjustment: associations with ambivalence over emotional expression

A sample of 90 older respondents (age range: 78-83 years) composed of 2 Holocaust groups (camp inmates and other survivors) and a comparison group completed questionnaires measuring ambivalence over emotional expression, positive and negative affect, and psychosocial adjustment. The Holocaust groups rated higher than the comparison group on negative affect and ambivalence over emotional expression and lower on psychosocial adjustment. Ambivalence over emotional expression mediated the effects of the Holocaust on negative affect. These data suggest that the effects of the Holocaust are evident 60 years later, highlighting the role of ambivalence over emotional expression in the well-being of Holocaust survivors.     

Adaptation to display rotation and display gain distortions during drawing

The relationship between movement extent and movement direction coding mechanisms was investigated using a visuomotor adaptation paradigm. To determine if these mechanisms are either modular or interdependent, young healthy college students were tested while they performed a visually guided drawing task that incorporated varying combinations of movement distance and direction distortions. Analysis of participants' standardized movement duration, initial directional error, and movement length over the course of the adaptation process revealed a certain degree of interdependence between direction and extent coding mechanisms. Specifically, changes in final adaptation levels and after-effects depended on the order of introduction of the visual distortions. This interaction can be characterized as unidirectional, where alterations in rotational feedback interfere with subsequent adaptation to gain changes, whereas alterations in "display gain" do not significantly impede the adaptation to "display rotation". Moreover, simultaneous exposure to gain and rotational distortions resulted in better learning. The results argue against an independent coding of movement direction and extent during adaptation by the central nervous system.     

Illness perceptions or recurrence risk perceptions: What comes first? A longitudinal cross-lagged examination among cardiac patients

Objectives: Previous research suggested that illness perceptions provide the basis for illness risk perceptions through an inductive reasoning process. This study aimed to assess the direction of relationships between illness and recurrence risk perceptions over time, among cardiac patients.

Design: A longitudinal study was conducted among 138 patients undergoing coronary angioplasty. Self-report questionnaires measured perceived recurrence risk and illness perceptions one day and one month after catheterisation.

Results: Cross-lagged Panel Model Analyses revealed that higher perceptions of timeline, consequences and emotional representations of illness at hospitalisation were associated with higher recurrence risk perceptions one month later. Perceived personal control was the only illness perception with bi-directional associations: higher perceived personal control at hospitalisation was associated with higher recurrence risk perceptions one month later; and higher recurrence risk perceptions at hospitalisation was associated with lower personal control one month later.

Conclusions: The findings suggest that the associations between recurrence risk and illness perceptions can only partly be explained by inductive reasoning. Halo effects and defensive processes are suggested as complementary explanations for the observed associations between risk and illness perceptions.

Mothers' citizenship status and household food insecurity among low-income children of immigrants

Recent data have shown that children of immigrant noncitizens experience more persistent and higher levels of food insecurity than the children of citizens following welfare reform. However, little is known about the range of factors that might explain different rates of food insecurity in the different populations. In this study, the authors used national data from the Early Childhood Longitudinal Study-Kindergarten cohort to assess this question, using multivariate probit regression analyses in a low-income sample. They found that households of children (foreign and U.S.-born) with noncitizen mothers are at substantially greater risk of food insecurity than their counterparts with citizen mothers and that demographic characteristics such as being Latina, levels of maternal education, and large household size explain about half of the difference in rates.     

Reliability of a Longitudinal Sequence of Scale Ratings

Reliability captures the influence of error on a measurement and, in the classical setting, is defined as one minus the ratio of the error variance to the total variance. Laenen, Alonso, and Molenberghs (Psychometrika 73:443–448, 2007) proposed an axiomatic definition of reliability and introduced the R _T coefficient, a measure of reliability extending the classical approach to a more general longitudinal scenario. The R _T coefficient can be interpreted as the average reliability over different time points and can also be calculated for each time point separately. In this paper, we introduce a new and complementary measure, the so-called R _Λ , which implies a new way of thinking about reliability. In a longitudinal context, each measurement brings additional knowledge and leads to more reliable information. The R _Λ captures this intuitive idea and expresses the reliability of the entire longitudinal sequence, in contrast to an average or occasion-specific measure. We study the measure’s properties using both theoretical arguments and simulations, establish its connections with previous proposals, and elucidate its performance in a real case study.

Measurement of Ability in Adaptive Learning and Assessment Systems when Learners Use On-Demand Hints

Adaptive learning and assessment systems support learners in acquiring knowledge and skills in a particular domain. The learners’ progress is monitored through them solving items matching their level and aiming at specific learning goals. Scaffolding and providing learners with hints are powerful tools in helping the learning process. One way of introducing hints is to make hint use the choice of the student. When the learner is certain of their response, they answer without hints, but if the learner is not certain or does not know how to approach the item they can request a hint. We develop measurement models for applications where such on-demand hints are available. Such models take into account that hint use may be informative of ability, but at the same time may be influenced by other individual characteristics. Two modeling strategies are considered: (1) The measurement model is based on a scoring rule for ability which includes both response accuracy and hint use. (2) The choice to use hints and response accuracy conditional on this choice are modeled jointly using Item Response Tree models. The properties of different models and their implications are discussed. An application to data from Duolingo, an adaptive language learning system, is presented. Here, the best model is the scoring-rule-based model with full credit for correct responses without hints, partial credit for correct responses with hints, and no credit for all incorrect responses. The second dimension in the model accounts for the individual differences in the tendency to use hints.
