基于遗传算法的模糊综合评价在心理测量中的应用 总被引:1,自引:0,他引:1
提出了运用模糊数学对利克特量表数据进行分析的方法, 探讨了人们在进行模糊综合评价时, 所采用的算子和对各个自变量的权重分配, 并且运用遗传算法(GA)来确定相关的权重。以大学生对康师傅红烧牛肉面的评价数据为例, 运用基于遗传算法的模糊综合评价方法, 发现男生采用了“最大最小”合成算子, 女生采用了“有界和、取小”合成算子。研究结果表明, 基于遗传算法的模糊综合评价方法可以对利克特量表的心理测量数据进行有效的分析。 相似文献

Analysing ordinal data is becoming increasingly important in psychology, especially in the context of item response theory. The generalized partial credit model (GPCM) is probably the most widely used ordinal model and has found application in many large-scale educational assessment studies such as PISA. In the present paper, optimal test designs are investigated for estimating persons’ abilities with the GPCM for calibrated tests when item parameters are known from previous studies. We find that local optimality may be achieved by assigning non-zero probability only to the first and last categories independently of a person's ability. That is, when using such a design, the GPCM reduces to the dichotomous two-parameter logistic (2PL) model. Since locally optimal designs require the true ability to be known, we consider alternative Bayesian design criteria using weight distributions over the ability parameter space. For symmetric weight distributions, we derive necessary conditions for the optimal one-point design of two response categories to be Bayes optimal. Furthermore, we discuss examples of common symmetric weight distributions and investigate under what circumstances the necessary conditions are also sufficient. Since the 2PL model is a special case of the GPCM, all of these results hold for the 2PL model as well. 相似文献

The purpose of the study was to evaluate the factor structure and the reliability of the Prosocial Behavior Scale (PBS). To our knowledge, no factorial validity of the multifactorial structure of PBS has been published to date. The psychometric characteristics of the PBS were examined in several samples of French adolescents (aged 11–19, N1 = 1141, N2 = 1071, and N3 = 1640) using Confirmatory factor analyses (CFA). The original four-factor structure was not confirmed due to lack of discriminant validity. CFA led us to retain a two-factor solution with a good fit and a satisfactory reliability. Furthermore, the results support the convergent validity of the PBS: helping and caring dimensions were positively correlated with empathy. In addition, partial measurement invariance across gender and grade was attested. In conclusion, the results indicate that the French version of the PBS is a useful instrument for the assessment of prosocial behaviors in adolescence. 相似文献

The experiences in close relationships revised (ECR-R) is widely used to assess romantic attachment dimensions. Investigating cultural limitations in its applicability is imperative. This study aims to examine the instrument’s: (1) factor structure in two large and normative samples of Greek (N = 1706, M age = 16.16; SD = 2.16; 49.7% male) and Cypriot (N = 1279; M age = 15.54; SD = 0.65; 44.9% male) adolescents; (2) measurement invariance between these groups, accounting for potential gender and age effects. Results supported the two-factor structure and indicated partial invariance of the constructs between Greek and Cypriot adolescents. Findings support limitations in the use of instruments adapted for Greece in Cyprus. 相似文献

Using Curriculum-Based Measurements for Program Evaluation: Expanding Roles for School Psychologists
Educators increasingly need to evaluate schoolwide reform efforts; however, complex program evaluations often are not feasible in schools. Through a case example, we provide a heuristic for program evaluation that is easily replicated in schools. Criterion-referenced interpretations of schoolwide screening data were used to evaluate outcomes associated with participation in four-year-old kindergarten. Nonparametric analyses allowed for group comparisons across early literacy screening outcomes. Risk ratios demonstrated that four-year-old kindergarten participants were less likely to score “at-risk” on kindergarten and first grade screenings. The methods employed meaningfully addressed local program effectiveness questions. Further, they were easily determined and disseminated. Implications for extensions of the heuristic to other evaluation questions and data sources as well as limitations of the approach are discussed. 相似文献

This study examined the relationship between proactive personality and career decision‐making self‐efficacy. In Study 1, the authors validated the Proactive Personality Scale–Korean Short Form, using the Rasch model with 315 participants, and found that fit statistics, point‐measure correlations, and item difficulty estimates satisfy the construct validity criterion. In Study 2, the authors administered the Proactive Personality Scale, Career Decision‐Making Self‐Efficacy Scale, and Career Search Self‐Efficacy Scale to 296 freshman and sophomore college students. Hierarchical regression analyses showed that proactive personality scores explain additional variance in both career decision‐making self‐efficacy and career search self‐efficacy scores. Implications for theory and practice are discussed. 相似文献

The Big Five Inventory–2 (BFI-2) uses 60 items to hierarchically assess the Big Five personality domains and 15 more-specific facet traits. The present research develops two abbreviated forms of the BFI-2—the 30-item BFI-2-S and the 15-item BFI-2-XS—and then examines their measurement properties. At the level of the Big Five domains, we find that the BFI-2-S and BFI-2-XS retain much of the full measure’s reliability and validity. At the facet level, we find that the BFI-2-S may be useful for examining facet traits in reasonably large samples, whereas the BFI-2-XS should not be used to assess facets. Finally, we discuss some key tradeoffs to consider when deciding whether to administer an abbreviated form instead of the full BFI-2. 相似文献

Racial identity means different things to members of different racial and ethnic groups in the United States. However, while the study of race and politics is often the study of White racial attitudes ( Dawson & Cohen, 2003 ), research on racial identity almost always refers to non-White identity. This article addresses this hole in the literature by examining the extent and effects of White identity. We compare White identification and Black identification using National Election Studies data (1972–2000) and examine the relationships between racial identity and racial and political attitudes. This study adds a missing case to the study of racial identity, tests how well the theories about the concept travel across cases, and highlights the need for more frequent studies of the racial identity of all groups. 相似文献
