Validity and Reliability of a Pre-Employment Screening Test: The Counterproductive Behavior Index (CBI)

The Counterproductive Behavior Index (CBI) is a 120-item, true-false questionnaire developed to assess five aspects of counterproductive workplace behavior: Dependability Concerns, Aggression, Substance Abuse, Honesty Concerns, and Computer Abuse, plus an overall measure of Total Concerns. It also yields a Good Impression score. To assess predictive validity, undergraduates with significant work experience simulated persons who had each of the five counterproductive behaviors but were exercising care not to get caught trying to conceal that behavior. All differences between simulated and normative responding were highly significant, with a median sensitivity of .89 for a specificity of .90. For similar participants, construct validity correlations ranged from .37 though .72 with a median of .50, and the correlation of CBI Total Concerns with a Total Validity Index was .66. Test-retest reliabilities of the CBI scales ranged from .79 to .94 with a median correlation of .87. These compare favorably with previously reported internal consistencies (Cronbach alphas). Analysis of the CBI scores of the original normative group at different levels of Good Impression showed that none of the six Concerns scores were affected by attempts to make a good impression until the Good Impression score reached the 90th percentile.

语音训练对幼儿英语语音意识和字母知识的促进

语音意识是影响英语阅读能力的关键因素。本研究结合语音教学法的思想,采用自编的教学材料和语音游戏,通过字母故事和语音训练游戏,训练儿童的语音意识。研究者在北京市一所普通幼儿园选取了无英语学习经验的3岁左右中国幼儿63名,随机分为实验组和控制组,经过8周的语音教学实验,发现接受语音教学的实验组儿童在音节意识、音韵意识、音素意识和字母识别等方面较接受普通英语教学的控制组都有显著提高。结果表明早期有针对性的语音训练可能能够更快地提高幼儿的语音意识。     

OBSERVATIONAL LEARNING AND THE EMERGENCE OF SYMMETRY RELATIONS IN TEACHING SPANISH VOCABULARY WORDS TO TYPICALLY DEVELOPING CHILDREN

One 9‐year‐old child was taught conditional discriminations between dictated names in Spanish and their corresponding pictures across three stimulus sets while her 10‐year‐old brother observed. Posttests revealed the emergence of symmetry relations in the form of oral naming skills by both children.     

A retrospective survey of community based utilization of Tay Sachs screening in Eight New Jersey counties

The purpose of this study was to determine the rate of utilization of Tay Sachs disease screening by the Ashkenazi Jewish population. Pregnant women who were referred to one of three genetic centers in New Jersey for amniocentesis unrelated to Tay Sachs screening were the study population. 4490 charts were reviewed retrospectively to determine the at risk population for Tay Sachs disease (Ashkenazi Jews) and whether or not patients and their spouses had elected Tay Sachs screening prior to referral. A group of 25 patients who did not elect screening were questioned as to their specific reason for declining Tay Sachs screening. Overall community utilization was 90%. Of the couples who did not elect screening, 64% felt that their risk to have an affected child was too small, 16% could not recall Tay Sachs screening being offered to them, 8% felt that screening was inconvenient. Tay Sachs screening as a voluntary preventive health care program has a high utilization rate in our study group.     

Education and testing strategy for large-scale cystic fibrosis carrier screening

Population-based screening for cystic fibrosis carrier mutations presents a number of challenges for genetic counselors, owing primarily to the inability of current DNA testing technology to identify all possible mutations and the difficulty involved in conveying the concept of residual risk to those patients who test negative. To address these issues, we are conducting a pilot study, as part of a consortium established by the National Center for Human Genome Research, to explore the efficacy, acceptance, and psychosocial impact of various approaches to carrier screening in an ethnically diverse Southern California population. This article reports the patient instructional and screening strategies we developed in the initial phase of the project in order to optimize our chances of answering these questions and delivering this service on a large scale.     

Update and Review: Maternal Serum Screening

Maternal serum levels of alpha fetoprotein (AFP), human chorionic gonadotropin (hCG), and unconjugated estriol (uE3) can be used to screen pregnancies for neural tube defects, Down syndrome, Trisomy 18, and pregnancy complications. This article summarizes the most recent information regarding maternal serum screening, including genetic counseling issues.     

Intervention and sleeper effects: A reply to Victoria Seitz

Victoria Seitz (Developmental Review, 1981, 1, 361–373) has misperceived and misunderstood our position (A. D. B. Clarke & A. M. Clarke, Developmental Review, 1981, 344–360). For example, our argument endorsed a transactional and not a main-effect model, nor was our aim to argue that early intervention has no important later consequences, nor did we dispute Consortium findings (I. Lazar & R. Darlington, Lasting effects after preschool, Washington, D.C.: DHEW Publication No. (OHDS) 79-30178, 1978). In fact, agreements with Seitz greatly exceed disagreements. Our skepticism about whether a behavioral treatment can have long-range effects without also having earlier ones remains. Long-term changes appear to result from ongoing long-term processes.     

Are General Practitioners Willing and Able to Provide Genetic Services for Common Diseases?

Primary care in the United Kingdom has been advocated as an optimal location for the provision of genetic services for common diseases. Little, however, is known about general practitioners' own views toward this suggestion or the possible demand for such services from patients. To assess general practitioners' attitudes to providing genetic services for common diseases, and to estimate the demand from patients for these services, we used a single-page postal questionnaire survey of all 359 general practitioners registered with the Oxfordshire Health Authority; 339 (94%) responded. These physicians reported that a mean 4.1 patients (95% CI, 3.3–4.9) out of every 1,000 consulting them were concerned about their own risk of a common disease associated with a diagnosis in a family member. Half of the general practitioners (95% CI, 45–56%) counseled about genetics in the last year. A majority of general practitioners accept the need to provide genetic services, but far fewer are competent to do so. Although 60% (95% CI, 55–65%) believed they should be involved with genetic screening for common diseases, only 29% (95% CI, 24–34%) felt sufficiently prepared to take family histories and draw pedigrees, and only 15% (95% CI, 11–19%) felt sufficiently prepared to counsel patients about their genetic test results. Given the necessary training and information, 63% (95% CI, 58–68%) and 64% (95% CI, 59–69%) were willing to provide these services. Even with training and information, not all would be willing to provide these services, and lack of time may be a major deterrent. Practice-enabling strategies, such as computerized aids in genetics, may be useful.     

The Concept of Abnormality in Medical Genetics

This paper explores usage of the concept ofabnormality in medical genetics and proposesdirectives for more careful usage of this concept.The conceptual difficulties are first explored, thena model is developed to assess actual usage, followedby analysis of a sample of genetic textbooks andgenetics literature. It appears that fact andvaluation are often intermingled, that referencestandards used to define 'genetic abnormalities' areoften not clear and that the concept of abnormality isoften used independent of the degree of certainty withwhich the altered genetype develops into a (seriously)harmful phenotype. On the basis of these findings itis argued that more restraint and more careful use ofthe concept of genetic abnormality of medical geneticsis appropriate as well as more agreement on the use ofreference standards.
