Crossing the North Sea seems to make DCD disappear: Cross-validation of Movement Assessment Battery for Children-2 norms

The Movement Assessment Battery for Children has been revised as the Movement ABC-2 (Henderson, Sugden, & Barnett, 2007). In Europe, the 15th percentile score on this test is recommended for one of the DSM-IV diagnostic criteria for Developmental Coordination Disorder (DCD). A representative sample of Dutch and Flemish children was tested to cross-validate the UK standard scores, including the 15th percentile score. First, the mean, SD and percentile scores of Dutch children were compared to those of UK normative samples. Item standard scores of Dutch speaking children deviated from the UK reference values suggesting necessary adjustments. Except for very young children, the Dutch-speaking samples performed better. Second, based on the mean and SD and clinical relevant cut-off scores (5th and 15th percentile), norms were adjusted for the Dutch population. For diagnostic use, researchers and clinicians should use the reference norms that are valid for the group of children they are testing. The results indicate that there possibly is an effect of testing procedure in other countries that validated the UK norms and/or cultural influence on the age norms of the Movement ABC-2. It is suggested to formulate criterion-based norms for age groups in addition to statistical norms.     

Norms for College Undergraduates for the Bem Sex-Role Inventory and the Wiggins Interpersonal Behavior Circle

Norms based on large random samples of introductory psychology college students are presented for the Bem Sex-Role Inventory (N = 1,133) and the Wiggins Interpersonal Behavior Circle (N = 564). The use of normative data, as compared with raw data or data standardized separately within studies, should result in more precise and meaningful measurement of subjects' locations on sex-role dimensions (i.e., instrumentality and expressiveness) by future researchers using these instruments, although norms should be updated to reflect future research results. Conventional definitions of moderately extreme and statistically extreme scores are presented for these instruments based on these norms, encouraging standardization of sample characteristics of future studies.

Addressing Issues in the Development and Use of the Composite International Reference Values as Rorschach Norms for Adults

This article describes 3 studies evaluating normative reference data for the Rorschach Comprehensive System (CS; Exner, 2003, 2007), with a particular focus on the viability of the Composite International Reference Values (CIRVs) that were compiled from 21 adult studies by Meyer, Erdberg, and Shaffer (2007). Study 1 documented how the CIRV norms are virtually identical when organized into 3 groups differentiated by the quality of their data collection effort, including an optimal group of 4 samples that relied on multiple experienced examiners and provided ongoing quality control over administration and coding. Analyses also showed that relative to the group of more optimal samples, the group of less optimal samples did not produce more variability in summary scores within or across samples or lower interrater reliability for coding. Study 2 used the existing CS reference norms to generate T scores for the CIRV means and documented how the CS norms make other samples of healthy nonpatients look psychologically impaired in multiple domains. Study 3 documented with examples from 4 different countries how 2 sets of within-country local norms produced notably different results on some variables, which compromises the ability of local norms to be used instead of the CIRVs. Taken together, the 3 studies provide support for the use of CIRVs in clinical practice as norms that are generalizable across samples, settings, languages, and cultures and that account for the natural variability that is present when clinicians and researchers contend with the ambiguity contained in the standard CS reference materials concerning the proper ways to administer and code. We conclude by urging CS users to rely on the CIRVs when making clinical inferences and to adopt alternative methods of ensuring they are following cohesively standardized administration and coding guidelines.     

A comparison of stimulus ratings made online and in person: Gender and method effects

In Experiment 1, separate samples rated nouns on danger, using either an online survey or the same survey in person. In Experiment 2, a single sample rated words on familiarity, using both methods. Women’s in-person and online ratings correlated significantly better than men’s. In-person ratings correlated significantly better with existing norms in 4 of 8 instances. There were significant effects of condition on mean ratings and completion times. Ratings from participants who withdrew from the experiment correlated significantly less well with existing norms than did ratings from those who completed the whole experiment, in 12 of 16 instances. Analysis of existing data showed that a different statistical conclusion is reached depending on whether in-person or online ratings are used. Furthermore, the categorization of 17.9% (Experiment 1) and 5.3% (Experiment 2) of the items as high or low depends on which ratings are used. Ratings gathered in person and online cannot be freely substituted.     

Scoring the DSM-IV personality disorders using the Five-Factor Model: development and validation of normative scores for North American, French, and Dutch-Flemish samples

Five-Factor Model (FFM) personality disorder (PD) counts have demonstrated significant convergent and discriminant validity with DSM-IV PD symptoms. However, these FFM PD counts are of limited clinical use without normative data because it is difficult to determine what a specific score means with regard to the relative level of elevation. The current study presents data from three large normative samples that can be used as norms for the FFM PD counts in the respective countries: United States (N = 1,000), France (N = 801), and Belgium-Netherlands (N = 549). The present study also examines the performance, with regard to diagnostic efficiency, of statistically-defined cut-offs at 1.5 standard deviations above the mean (T > or = 65) versus previously identified cut-offs using receiver-operator characteristics (ROC) analyses. These cut-offs are tested in three clinical samples-one from each of the aforementioned countries. In general, the T > or = 65 cut-offs performed similarly to those identified using ROC analyses and manifested properties relevant to a screening instrument. These normative data allow FFM data to be used in a flexible and comprehensive manner, which may include scoring this type of personality data in order to screen for DSM-IV PD constructs.     

Neuropsychological test norms controlled for physical health: Does it matter?

The objective of the present study was to investigate the effects of physical health on neuropsychological test norms. Medical and neuropsychological data from 118 healthy volunteer controls, aged 26–91 years, were collected during five recruitment occasions. The examinations included a clinical investigation, brain neuroimaging, and a comprehensive neuropsychological test battery. Test‐specific statistical regression‐weights for age, education and gender were calculated to establish preliminary test norms. Hierarchical regression analyses demonstrated that control in addition for physical health moved best performance from age 60 to 65 for abstraction; replaced a plateau above age 70 for verbal fluency, with a continued rise in performance; eliminated significant negative influences of age on auditory learning, spatial reasoning and complex copying; reduced them on wordlist recall, psychomotor speed, visual scanning and mental shifting; and slightly reduced negative influences of low education on most verbal tests, several memory tests, and psychomotor speed, indicating rises in normative scores of up to 0.8 SD at age 80 and 0.4 SD at age 60. No differences were found at age 40. Although the sample size is not adequate to be used for normative data, the findings indicate that norms uncontrolled for health overestimate the negative influence of advanced age and low education, implying a risk of drawing false diagnostic conclusions.     

The interplay of individual differences,norms, and group identification in predicting prejudiced behavior in online video game interactions

Despite the increasing popularity of video games and the diversity of people who play, prejudice remains common in online gaming. In the current study, we use structural equation modeling to test the role of social norms, individual differences, and gamer identification as predictors of how likely someone is to report engaging in prejudiced behavior while playing online video games. We also test the relative importance of these predictors to assess how likely people are to confront prejudice when it occurs in online video games. Participants (N = 384) completed a series of questionnaires to assess their attitudes and perceptions of online gaming norms, as well as to report their own prejudiced and confrontation behavior in video games. We found that both social norms and individual differences are significant predictors of behavior in online gaming. The more normative people report prejudice to be, the more they report making prejudiced comments. Similarly, the more normative confrontation of prejudice is reported to be, the more likely people are to report confronting prejudice. The more people endorsed generally prejudiced attitudes, the more likely they were to report making prejudiced remakes in online gaming and the less likely they were to report confronting prejudiced remarks. These results provide a foundation to inform interventions to reduce prejudice in gaming and indicate that both individual differences and norms are important to consider when designing interventions.     

Psychometric properties and reference data for Danish versions of Free and Cued Selective Reminding Test,Category Cued Memory Test and Logical Memory

Memory assessment is a key element in neuropsychological testing. Gold standard evaluation is based on updated normative data, but in many small countries (e.g. in Scandinavia) such data are sparse. In Denmark, reference data exist for non‐verbal memory tests and list‐learning tests but there is no normative data for memory tests which capture narrative recall and cued recall. In a nation‐wide study, Free and Cued Selective Reminding Test (FCSRT ), WMS ‐III Logical Memory (LM ) and a newly developed test Category Cued Memory Test (CCMT ‐48) were applied in 131 cognitively intact persons (aged 60–96 years). Regression‐based reference data for Danish versions of FCSRT , CCMT ‐48 and LM adjusted for age, education and gender are provided. Gender and age‐group had a significant impact on the expected scores, whereas the effect of education had a limited effect on expected scores. Test performances were significantly correlated in the range 0.21–0.51. Based on these findings and previous results it may be relevant to assess both free recall, cued recall and recognition to tap the earliest changes associated with neurodegeneration, and this study therefore provides an important supplement to existing Danish normative data. Future studies should investigate the discriminative validity of the tests and the clinical utility of the presented reference data.     

眼睛效应不稳定与感知规范：一个新视角

眼睛效应指人们面对眼睛或类似眼睛的图案时会发生行为改变的现象。但是, 眼睛效应的稳健性备受争议, 主要有4种观点：促使人们更亲社会、更遵守社会规范、降低反社会行为、无效果。结合规范错觉和创新扩散理论, 基于感知规范的视角, 当感知亲社会规范流行程度较高时, 眼睛效应既会“促进亲社会行为”或“促进人们遵守社会规范”, 也会“降低反社会行为”; 但当感知亲社会规范流行程度较低时, 眼睛效应对一些反社会行为“无效果”; 当规范错觉较大且无规范干预时, 眼睛效应同样对一些反社会行为无效果。因此, 将以上4种争议观点整合为“不同感知规范条件下的眼睛效应”, 揭示了眼睛效应不稳定的原因, 为未来实证研究和实践应用提供理论基础。     

The silence of the library: environment,situational norm,and social behavior

On the basis of the idea that situational norms are mentally represented as associations between environments and normative behavior, it was proposed that an environment can automatically direct normative behavior. More specifically, when situational norms are well-established (e.g., when entering the library, one should be silent), an environment is capable of automatically activating mental representations of normative behavior and the behavior itself. In these experiments, participants were exposed to pictures of environments, and effects on accessibility of representations of normative behavior and on actual behavior were assessed. Results indicated that representations of behavior and actual behavior itself are activated automatically when (a) goals to visit the environment are active and (b) strong associations between environment and normative behavior are established.     

Health‐adjusted neuropsychological test norms based on 463 older Swedish car drivers

There is a need for improved normative information in particular for older persons. The present study provides neuropsychological test norms on seven cognitive tests used in a sample representing the general older driving population, when uncontrolled and controlled for physical health. A group of 463 healthy Swedish car drivers, aged 65 to 84 years, participated in a medical and neuropsychological examination. The latter included tests of visual scanning, mental shifting, visual spatial function, memory, reaction time, selective attention, and simultaneous capacity. Hierarchical regression analyses demonstrated that, when uncontrolled for health, old age was associated with significant impairment on all seven tests. Education was associated with a significant advantage for all tests except most reaction time subtests. Women outperformed men on selective attention. Controlling for health did not consistently change the associations with education, but generally weakened those with age, indicating rises in normative scores of up to 0.36 SD (residual). In terms of variance explained, impaired health predicted on average 2.5%, age 2.9%, education 2.1% and gender 0.1%. It was concluded (1) that individual regression‐based predictions of expected values have the advantage of allowing control for the impact of health on normative scores in addition to the adjustment for various demographic and performance‐related variables and (2) that health‐adjusted norms have the potential to classify functional status more accurately, to the extent that these norms diverge from norms uncontrolled for physical health.     

The identification of deviance: A conceptualization and initial test of a model of social norms

This paper outlines and initially tests a conceptual model of social norms, within the context of a general research framework for examining how deviant behaviour is identified and responded to. Norms are examined vis-a-vis (a) the structure of beliefs and expectancies toward one's own and [deviant] individual's behaviour, and (b) normative focus, representing the social context of behaviour and the nature of the group the norm is shared within. The results showed both of these constituents to be salient to the application of the model to the identification of alcohol abuse, particularly in terms of (i) the relationship between normative structure and the recognition of and evaluation of deviant drinking, (ii) a strong influence of social context on norms and (iii) the finding of powerful differences in normative structure in socio-economically different communities. This latter effect is discussed in terms of the [social ecology] of norms. It is hoped that this model will have heuristic value in expediting theory based studies of both normative regulation, and perceptions of abnormal behaviour.     

How Many is Enough? Determining Optimal Sample Sizes for Normative Studies in Pediatric Neuropsychology

The purpose of this investigation was to determine how confidence intervals (CIs) for pediatric neuropsychological norms vary as a function of sample size, and to determine optimal sample sizes for normative studies. First, the authors calculated 95% CIs for a set of published pediatric norms for four commonly used neuropsychological instruments. Second, 95% CIs were calculated for varying sample size (from n?=?5 to n?=?500). Results suggest that some pediatric norms have unacceptably wide CIs, and normative studies ought optimally to use 50 to 75 participants per cell. Smaller sample sizes may lead to overpathologizing results, while the cost of obtaining larger samples may not be justifiable.     

A correction for recruitment bias in norms derived from meta-analysis

Normative comparisons are an integral component of neuropsychological test interpretation and provide the basis for an inference of abnormal function and impairment. In order to remedy a deficit of normative standards for a large number of neuropsychology tests, Mitrushina, Boone, Razani, and D'Elia (2005) used the meta-analysis of studies that incorporated normal volunteers to create a type of normative standard for many tests in neuropsychology that were not adequately normed in the past. The present study examined this method by contrasting meta-analysis norms of the Wechsler Adult Intelligence Scale-Revised (WAIS-R; Wechsler, 1981) with its published quota norms. The study examined 12 experimental studies of the WAIS-R that included normal, control volunteers (N = 2,147). These were combined by meta-analysis, and the summary scores were compared. The meta-analysis revealed a significant sampling bias with studies recruiting more White and higher educated respondents than indicated by the U.S. Census. This bias was successfully corrected using Monte Carlo simulation and adjustments for quota sampling. The corrections could be applied to all meta-analysis norms currently in use and bring them in line with the U.S. Census demographics.     

MMPI Adolescent Norms: Patterns and Trends Across 4 Decades

This article examines central issues involving the accuracy of Minnesota Multiphasic Personality Inventory (MMPI) adolescent norms through examination of findings from eight investigations (n = 17,286), reporting MMPI mean values for samples of normal adolescents conducted between 1949 and 1964, and four studies (n = 1,758), based on adolescent samples collected since 1975. issues related to sex and racial differences in adolescent samples are also examined. In addition, MMPI data from 1,315 normal adolescents, collected at the Mayo Foundation, and from 217 normal adolescents, collected in Norfolk, Virginia, are evaluated in relation to adult normative values on the Harris-Lingoes (Harris & Lingoes, 1955) content subscales to identify unique characteristics of adolescents' response patterns. Results support the adequacy of the adolescent norms, developed by Marks, Seeman, and Hailer (1974), for evaluation of samples of normal adolescents collected between 1947 and 1965. MMPI patterns, produced by contemporary samples of adolescents collected since 1975, are elevated above the Marks et al. norms on most clinical scales. This latter finding indicated the need for the development of new adolescent norms that more precisely reflect current adolescent response frequencies and patterns. Finally, results from Harris-Lingoes subscales are reviewed to highlight unique aspects of adolescent developmental experience and to underscore the necessity of development of age appropriate adolescent norms for MMPI special scales.
