During the twentieth century, many authors have offered their contributions to the controversial subject of test validity.
Thus, the concept of validity seems to be quite a simple idea until one looks at the literature on the subject. Validity can
be defined as “the degree to which the test actually measures what it purports to measure,” but the question of how to define
validity and how to test it is both an old question and a never-ending story. We have to deal with it every time we are asked
to use a test that already exists or to construct a new one. Therefore, the article aims at dealing with test validity in
order to point out the different (qualitative and quantitative) aspects of validity, which have emerged from empirical research
and theoretical reflections. It is thought as a critical review which can be useful both to theoretically oriented and practically
inclined psychologists. 相似文献

The paper presents the multidimensional measurement as a transparent and easy-to-interpret method to measure poverty, where poverty is measured with a set of direct and indirect poverty indicators side-by-side. Multidimensional measurement is formalised and compared to the traditional, one-dimensional measurement. This formalisation is based on the idea about a set of indicators that are measuring different manifestations of the same latent variable. The Latent Class Model (LCM) is proposed as a method to select a valid and reliable set of poverty indicators for multidimensional measurement. The LCM is used to test if these different poverty indicators really measure the same latent referent – an assumption on which the multidimensional measurement is based. Before this method presented here, constructing and selecting indicators for the multidimensional measurement of poverty has relied practically on theory and substance only. Naturally, the method presented here can be used generally for studying and developing multidimensional measurements. 相似文献

This paper studies how dyadic social support is affected by heterogeneity of the partners. We distinguish heterogeneity with respect to three parameters the likelihood of needing support; the benefits from receiving support; and the costs of providing support. Hypotheses are based on a game-theoretic analysis of an iterated support game. First, we predict that heterogeneity in one of the parameters hampers social support. Second, we predict that under heterogeneity with respect to two of the parameters, support is most likely if there is a specific heterogeneous distribution such that heterogeneity in one parameter ‘compensates’ for heterogeneity in the other parameter. If there is no compensation social support is even more hampered. The hypotheses have been tested by experimental data with a mixed within-subject, between-subject design. The data gives support to the hypotheses. 相似文献

International assignees face cultural adjustment challenges in their host countries in work and nonwork situations. At the same time, social capital theory suggests that individuals can access and mobilize resources from their social networks. We explore the use of social networks by international assignees from a non-governmental organization in their cross-cultural adjustment to the host country. Specifically, we are interested in the individuals who directly provided support to the expatriate, a network that we term the ‘current assignment support network’. We focus on the size, type and frequency of contact of the international assignee's support network, and investigate to what extent these variables can predict overall cultural adjustment to the host country, or separate dimensions of cultural adjustment such as interaction adjustment, general adjustment and work adjustment. Our findings indicate that certain characteristics of the international assignee's current assignment support network do impact their cultural adjustment to the host country, but that the effects are moderated by whether the assignee has prior international experience. 相似文献

Two existing measures of career motivation were used to collect data from a sample of Canadian managers and professionals recently displaced due to downsizing. Measurement models assessed the unidimensionality, reliability and discriminant validity of career motivation sub-domains while structural rnodcls were used to assess convergent validity. The career resilience construct received the most support but propositions about career identity end insight were also supported. The results clarify the riomological net of career motivation theory and produce an integrated, composite career motivation scale. 相似文献
