Spirituality plays an important role in cancer coping among African Americans. The purpose of this study was to report on the initial psychometric properties of instruments specific to the cancer context, assessing the role of spirituality in coping. Items were developed based on a theoretical model of spirituality and qualitative patient interviews. The instruments reflected connections to self, others, God, and the world. One hundred African American cancer survivors completed the instruments by telephone. The instruments showed adequate internal reliability, mixed convergent validity, discriminant validity, and interpretable factor structures. 相似文献

We present age-of-acquisition (AoA) ratings for 30,121 English content words (nouns, verbs, and adjectives). For data collection, this megastudy used the Web-based crowdsourcing technology offered by the Amazon Mechanical Turk. Our data indicate that the ratings collected in this way are as valid and reliable as those collected in laboratory conditions (the correlation between our ratings and those collected in the lab from U.S. students reached .93 for a subsample of 2,500 monosyllabic words). We also show that our AoA ratings explain a substantial percentage of the variance in the lexical-decision data of the English Lexicon Project, over and above the effects of log frequency, word length, and similarity to other words. This is true not only for the lemmas used in our rating study, but also for their inflected forms. We further discuss the relationships of AoA with other predictors of word recognition and illustrate the utility of AoA ratings for research on vocabulary growth. 相似文献

Assessing reliability of situational judgment tests (SJTs) in high‐stakes situations is problematic with reliability inappropriately measured by Cronbach's alpha when test items are heterogeneous. We computed the corrected, weighted mean alpha from 56 alpha coefficients, which produced a value of α = .46 and reviewed appropriate types of reliability to use with SJTs. In the current longitudinal study, SJT test–retest reliability was r = .82, compared with internal consistency, α = .46, and stratified alpha, α = .45 at Time 1 and α = .52 and stratified α = .51 at Time 2. We used a student sample (Time 1: n = 185; Time 2: n = 132) with items from a credentialing exam with ‘should do’ instructions. The SJT correlated significantly with cognitive ability, r = .30, and agreeableness, r = .24. In Study 2, we assessed test–retest reliability with Human Resource professionals (Time 1: n = 94; Time 2: n = 32) who had been recently credentialed and who participated in a pilot test of new SJT items with ‘most likely/least likely do’ response options. The SJT test–retest reliability was r = .66 compared with internal consistency, α = .43 and stratified α = .47 at Time 1 and α = .61 and stratified α = .67 at Time 2. We discuss the theoretical implications of the Study 1 results as well as the practical implications for use of SJTs in credentialing examinations. 相似文献

In coincidence‐timing studies, children have been shown to respond too early to slower stimuli and too late to faster stimuli. To examine this velocity effect, children aged 6, 7.5, 9, 10.5, and adults were tested with two different velocities in a prediction‐motion task which consisted of judging, after the occlusion of the final part of its path, the moment of arrival of a moving stimulus towards a specified position. A similar velocity effect, resulting in later responses for the faster velocities than for the slower, was found primarily in the three younger groups of children (for the longer occlusion conditions: 600–1,320 milliseconds). However, this effect was not seen in all children in these groups. Individual analyses showed that this velocity effect, when present, is linked to the use of distance rather than time information, or to the confusion between these in extrapolating the occluded trajectories. The tendency to use one type of information or the other is a good predictor of accuracy and variability in this task and a good indicator of the development stage of the participants. Across development, children tend to initially use distance information with poor accuracy but relative consistency in responses. In a second stage, they use time and distance information alternatively across trials trying to find a better source of information with still poor accuracy and now great variability. In a final stage, they use time information to reach consistency and accuracy in their responses. This chronology follows the stages proposed by Savelesbergh and Van der Kamp (2000) explaining development with an initial stage of ‘freezing’ non‐optimal relationships between information and movement, then a ‘freeing’ stage during which new solutions are searched for, and finally an ‘exploiting’ stage with an optimal relationship between information and movement. 相似文献
