“…Nor were we able to find a discussion of why individuals answering "yes" to at least seven of the ten questions are deemed time-crunched. Thus, the question that needed to be asked first was whether the time-crunch scale is a theoretically meaningful construct (Piazza 1980). As Beaujot and Andersen (2007) point out, the time-crunch scale is a somewhat problematic measure because it includes a broad range of questions that are not necessarily coherent in terms of their content.…”

“…Single-item indicators are problematic; when they are coded on a nominal level of measurement, they lack explanatory power and are insufficiently reliable indicators of the construct being measured, particularly when it is as complex as the work-family conflict. Thus, evidence provided by multiitem indicators is often more persuasive than that based on a single-item indicator (Piazza 1980). Grzywacz and Carlson (2007) argue that recent theoretical and conceptual developments of work-family balance do not reflect the vast academic and popular interest in the issues.…”

The issue of work and family balance has been on the agenda of many governmental and non-governmental organizations in recent years and has led to the adoption of various policies. However, combining work and family responsibilities remains a challenge for many parents. In this paper, we examine the work-family conflict experienced by Canadian working parents. For the purpose of this paper, work-family conflict is conceptualized as the time-related stress arising from the competing demands of the different roles imposed on working parents. Our objective is three-fold. First, we take a critical look at how time stress has been conceptualized and measured in previous studies. Using data from the 2005 Canadian General Social Survey on time use, we suggest an alternative multi-item scale. Second, we examine the impact of different predictors on parents' time stress, paying special attention to the impact of work-related factors. Finally, we discuss the impact of provincial variations in family policy on parents' time stress. Although Québec has introduced a number of family-oriented policies, we do not find evidence that these policies have resulted in less time stress for working parents in Québec. La balance entre le travail et la famille est un sujet qui a été présent sur l’agenda de plusieurs gouvernements et organisations non-gouvernementales au cours des dernières années et qui a donné lieu à l’adoption de diverses politiques. Cependant, la combinaison des responsabilités reliées au travail et à la famille demeure un défi pour de nombreux parents. Dans ce papier, nous examinons le stress temporel (time stress) vécu par les parents Canadiens qui ont un emploi rémunéré. Notre objectif est triple. Premièrement, nous portons un regard critique sur la façon dont le stress temporel a été conceptualisé et mesuré dans les études antérieures. Sur la base des données de l’enquête canadienne générale sur l’emploi du temps de 2005, nous suggérons une échelle multi-items. Deuxièmement, nous examinons l’impact de différentes variables sur le stress temporel des parents tout en portant une attention toute spéciale sur les variables reliées au travail. Finalement, nous discutons de l’impact des variations provinciales en matière de politique familiale sur le stress temporel des parents. Bien que le Québec ait introduit un nombre de politiques reliées à la famille, nous n’obtenons pas de résultats qui suggèrent que ces politiques ont réduit le stress temporel pour les parents québécois qui ont un emploi.

“…While item-to-criterion assessment has been discussed as one potential way to decide to retain or discard items (e.g., Ghiselli et al, 1981), a summary index for the test, based on these item indices has not been fully described. This paper offers a method for doing so and was developed based on the item selection technique described by Piazza (1980). As will be shown Piazza's method, and the Piazza's P 2 index resulting from it, suffers from some serious limitations.…”

While most validity indices are based on total test scores, this paper describes a method for quantifying the construct validity of items. The approach is based on the item selection technique originally described by Piazza in 1980. Unfortunately, Piazza's P2 index suffers from some substantial limitations. The Dm coefficient provides an alternative which can be used for item selection and provides a validity index for a set of items. The index is similar to that of traditional criterion-related validity indices. Criterion-related validity is used to demonstrate the accuracy of hypothesized relations of the measure with outcome variables of interest in research and practice. This method may be useful when the sample of items or persons is small, rendering more traditional approaches such as factor analysis or item response theory inappropriate. An example of how to use the technique is provided.
