Sociometric measures have been used frequently to measure social status; however, reliable sociograms for young children usually involve time-consuming administrations. A group-administered, peer-rating sociogram, the Sociometric Peer-Rating Scale (SPRS), was devised and given to 217 first and second graders. Concomitantly, teacher nominations of children most liked, aggressive, or withdrawn and behavioral observations of the high- and low-SPRS children were obtained. After 7 months, the SPRS was readministered. On a separate population of eight kindergarten children, this sociogram and a similar, individually administered sociogram were given. Normative data, test-retest reliability, and split-half reliability were reported. The test-retest reliability was comparable to the reported reliability of other peer-rating sociograms, and the SPRS correlated significantly with teacher ratings of aggressiveness and likability and with the individually administered sociogram. The number of positive interactions was significantly different for high-versus low-SPRS children. The usefulness of the SPRS as a measure of social competence was discussed.This research was submitted by the author in partial fulfillment of the requirements of a master's degree at the Florida State University.I would like to thank the Master's committee, Wallace Kennedy, William Pelham, and Joseph Torgesen, and the participating schools, Developmental Research School of Florida State University and Woodville Elementary School of the Leon County School District, for their assistance in this study. 相似文献

Portable electronic data collection devices permit investigators to collect large amounts of observational data in a form ready for computer analysis. These devices are particularly efficient for gathering continuous data on multiple behavior categories. We expect that the increasing availability of these devices will lead to greater use of continuous data collection methods in observational research. This paper addresses the difficulties encountered when calculating traditional interobserver agreement statistics for continuous, multiple-code scoring. Two alternative strategies are described that yield interobserver agreement values based on the exact time of behavior code entries by the primary and secondary observers.Work on this paper was supported in part by NICHD Grants P01HD15051 and R01HD17650 and Office of Special Education and Rehabilitation Services Grant G008302980. 相似文献

Under the assumption of normality, a formula is derived for the reliability of the maximum score. It is shown that the maximum score is more reliable than each of the single observations, but less reliable than their composite score. 相似文献

In a variety of measurement situations, the researcher may wish to compare the reliabilities of several instruments administered to the same sample of subjects. This paper presents eleven statistical procedures which test the equality ofm coefficient alphas when the sample alpha coefficients are dependent. Several of the procedures are derived in detail, and numerical examples are given for two. Since all of the procedures depend on approximate asymptotic results, Monte Carlo methods are used to assess the accuracy of the procedures for sample sizes of 50, 100, and 200. Both control of Type I error and power are evaluated by computer simulation. Two of the procedures are unable to control Type I errors satisfactorily. The remaining nine procedures perform properly, but three are somewhat superior in power and Type I error control.A more detailed version of this paper is also available. 相似文献

This study investigated the stability of the Millon Clinical Multiaxial Inventory (MCMI) in a sample of psychiatric inpatients over a longer time period and from different perspectives than previous reliability studies. Test-retest reliability was assessed from three perspectives: correlation/regression, equivalence of dimensional structures across testings upon different admissions, and stability of personality style across testings. Some stability from a correlational perspective was found, with higher stability estimates indicated for the basic personality scales in comparison with the clinical symptom scales which is consistent with Millon's theory. The internal structure of the MCMI was essentially identical across testings. Although source of reinforcement and instrumental or coping style were stable across testings beyond chance, the MCMI profiles of a considerable number of subjects were inconsistent across testings. Correspondingly, clinicians should be cautious in using the MCMI to make categorical decisions regarding personality style with inpatients who are tested at admission and who have had repeated hospitalizations. 相似文献

How changes in the interobserver agreement and disagreement cells in the reliability matrix are reflected differently in eight commonly used reliability indices is shown graphically. Indices which take into account expected chance difference are compared to those indices which do not. Differences between indices which do and do not treat the agreement and the disagreement cells equally are also illustrated. 相似文献

The Dating Anxiety Survey (DAS) was constructed to assess dating anxiety in males and females. Factor analysis of the survey revealed three factors: passive contact, active intentions for dating, and dating interactions. The reliabilities of the three subscales, as determined by coefficient alpha, were .87, .91, and .93 for males and .90, .90, and .92 for females, respectively. Correlations with dating history and a measure of social anxiety were generally of a low but significant magnitude, providing some support for concurrent validity. The results of the factor analysis lend support to the construct validity of the DAS. These findings suggest that the DAS is a potentially useful instrument in the self-report of dating anxiety.Portions of this paper were presented at the meeting of the Southeastern Psychological Association, Atlanta, GA, March 1983. 相似文献

A new form (VI) of the Sensation Seeking Scale (SSS) was developed which separates reports of past experiences from desired or intended future experiences on both Disinhibition (Dis) and Thrill and Adventure Seeking (TAS) factors. Factor analyses were used to select items for the scales. High internal reliabilities were found for the Experience-Dis, Intention-TAS, and Intention-Dis scales, but only moderate reliability was found for the Experience-TAS scale. Retest reliabilities were high for all scales. The Experience-TAS and -Dis scales were highly correlated for males but not for females. The Experience- and Intention-TAS scales were moderately correlated, and the Experience- and Intention-Dis scales were highly correlated for both sexes. Both the TAS and the Dis scales on form V were highly correlated with the corresponding Intention scales on form VI. Uses for the new SS scales in individual assessment are suggested.A copy of SSS form VI may be obtained from the author. 相似文献

Let Σ
x
be the (population) dispersion matrix, assumed well-estimated, of a set of non-homogeneous item scores. Finding the greatest
lower bound for the reliability of the total of these scores is shown to be equivalent to minimizing the trace of Σ
x
by reducing the diagonal elements while keeping the matrix non-negative definite. Using this approach, Guttman's bounds are
reviewed, a method is established to determine whether his λ4 (maximum split-half coefficient alpha) is the greatest lower bound in any instance, and three new bounds are discussed. A
geometric representation, which sheds light on many of the bounds, is described.
