The National Commission for the Protection of Human Subjects of Bio-medical and Behavioral Research ended its work by substantially endorsing the status quo which places primary reliance on local Institutional Review Boards for subject protection. This was predictable because of the commission's researcher-dominated composition which permitted it to assume that(1) research is good;(2) experimentation is almost never harmful to subjects; and (3) researcher-dominated IRBs can adequately protect the interests of human subjects. The successor Presidential Commission can learn much by reexamining these premises.  相似文献

United States federal regulations for pediatric research with no prospect of direct benefit restrict institutional review board (IRB) approval to procedures presenting: 1) no more than “minimal risk” (§ 45CFR46.404); or 2) no more than a “minor increase over minimal risk” if the research is commensurate with the subjects' previous or expected experiences and intended to gain vitally important information about the child's disorder or condition (§ 45CFR46.406) (DHHS 2001). During the 25 years since their adoption, these regulations have helped IRBs balance subject protections with the pursuit of scientific knowledge to advance children's welfare. At the same time, inconsistency in IRB application of these regulations to pediatric protocols has been widespread, in part because of the ambiguity of the regulatory language. During the past decade, three federally-charged committees have addressed these ambiguities: 1) the National Human Research Protections Advisory Committee (NHRPAC) (Washington, DC), 2) the Institute of Medicine (IOM) Committee on the Ethical Conduct of Clinical Research Involving Children (Washington, DC); and 3) the United States Department of Health and Human Services Secretary's Advisory Committee for Human Research Protections (SACHRP) (Washington, DC). The committees have reached similar conclusions on interpretation of language within regulations § § 45CFR46.404 and 406; these conclusions are remarkably consistent with recent international recommendations and those of the original National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research (1977) National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. 1977. Report and recommendations: Research involving children, Washington, DC: U.S. Government Printing Office.  [Google Scholar] report from which current regulations are based. Drawing on the committees' public reports, this article identifies the ethical issues posed by ambiguities in regulatory language, summarizes the committees' deliberations, and calls for a national consensus on recommended criteria.  相似文献

The aim of this research is to adapt the Quality of Work Life Scale developed by Sirgy et al. (Social Indicators Research, 55, 241–302, 2001) to Turkish culture, and to examine its psychometric properties. The research has been conducted on 254 academics who are affiliated to the Faculty of Education and Faculty of Science and Letters of four different universities in Ankara, Turkey. In order to provide the lingual equivalence, bilingual group pattern was used, and an English version of the scale was applied to a group of 34 academicians who are fluent in both English and Turkish. Nearly 1 month after this application, the Turkish version of the same form was applied once again to the same 34 people. The construct validity of the scale was conducted by using the Confirmatory Factor Analysis method. As a result of the study, it was determined that the original scale and its Turkish form yielded similar results. The fact that internal consistency is high is proved. Croanbach alpha coefficient was found as 0.84. This result indicates that the internal consistency of the test and accordingly the reliability are high and close to the original QWL scale. As a result of the Confirmatory Factor Analysis applied, it was determined that the Turkish form gave a factorial structure which was similar to the original scale and that no problems occurred in the course of using the scale total points. It is concluded that this scale, with its extremely comprehensible language, will contribute to defining the level of quality of the work life of those who work in Turkey and understand their behaviors and attitudes towards their work.  相似文献

There are points of convergences between Positive Psychology and Indian Psychology. But we do have to cross many barriers and travel some distance on converging pathways for the potential synergies between these fields to manifest. There are indicators in the global literature that Positive Psychology is maturing as an approach but this is yet to become very evident in the Indian research on Positive Psychology. Systematic efforts at discovering convergences between Indian Psychology and Positive Psychology can go a long way in enriching our understanding of well being.  相似文献

A taxonomy of literature reviews in education and psychology is presented. The taxonomy categorizes reviews according to: (a) focus; (b) goal; (c) perspective; (d) coverage; (e) organization; and (f) audience. The seven winners of the American Educational Research Association’s Research Review Award are used to illustrate the taxonomy’s categories. Data on the reliability of taxonomy codings when applied by readers is presented. Results of a survey of review authors provides baseline data on how frequently different types of reviews appear in the education and psychology literature. How the taxonomy might help in judging the quality of literature reviews is discussed, along with more general standards for evaluating reviews.  相似文献

Low-cost electronic experiment control boards (ECBs), developed by Walter and Palya (1984), were constructed and implemented for use at the Naval Aerospace Medical Research Laboratory. Each ECB was wired to control experiments using animals as subjects. The ECBs have been connected to IBM-compatible microcomputers and serve essentially as intelligent interfaces between the subject and the microcomputer. Relative advantages and disadvantages of the control board, including construction and programming techniques, as well as cost, are discussed.  相似文献

With data gathered from 96 female college students, intercorrelations were examined among self-concept ratings of masculinity and femininity, and scales from two personality-trait measures of masculinity and femininity—the Adjective Check List (ACL) and the Extended Personal Attributes Questionnaire (EPAQ). The sign and magnitude of the correlations between pairs of measures were successfully predicted on the basis of the congruence between measures of both the gender relevance and the desirability of the self-rated traits comprising each measure. The desirability of the trait items employed in self-report personality-trait scales of masculinity and femininity evidently introduces methods variance that can either inhibit or potentiate the relationship with other scales composed predominantly of either desirable or undesirable traits. When balanced for the desirability of trait items, personality-trait scores of masculinity and femininity were substantially inversely correlated with each other, and only marginally correlated with self-concept ratings of masculinity and femininity, but these correlations remained in the anticipated directions. This result is consistent with the findings of Pedhazur and Tetenbaum (“Bem Sex Role Inventory: A Theoretical and Methodological Critique,” Journal of Personality and Social Psychology, 1979, 37, 996–1016), and supports Spence's (Masculinity, Femininity, and Gender-Related Traits: A Conceptual Analysis and Critique of Current Research,” In B. A. Maher and W. B. Maher (Eds.), Progress in Experimental Research, Vol. XIII, Normal Personality Processes, New York: Academic Press, 1984) position that personality traits should be viewed as only one of many possible referents for gender/sex role identity.  相似文献

Research on children raises major ethical issues, the most important being the inability of the subjects to provide freely given informed consent. Committees in Canada and the United States charged with formulating recommendations for the protection of human subjects in research came to some fundamentally different conclusions. Two of these are discussed as they apply to children: first the distinction between therapeutic and non-therapeutic research, recognized implicitly by the National Commission (U.S.A.) and deliberately avoided by the Medical Research Council Working Group (Canada); and second, the looser relation between local committees and Council as defined by guidelines in Canada and the tighter relation between the institutional review committees and the Department of Health, Education and Welfare defined by regulations in the United States.  相似文献

The validity of the A-State Scale of the State-Trait Anxiety Inventory and the Zung Self-Rating Depression Scale was assessed using data from a general health survey. Depression and anxiety states were found to coexist, however, evidence from a factor analysis, showing items from the two tests loaded on separate factors, demonstrated that these states can be measured independently. Both the A-State and the Zung Scales were found to comprise two factors, and for each scale, one factor consisted of positively phrased items, and the other of negative items. The implications of these findings for the construct validity of the two scales are discussed.  相似文献

The paper argues that on three out of eight possible hypotheses about the EPR experiment we can construct novel and realistic decision problems on which (a) Causal Decision Theory and Evidential Decision Theory conflict (b) Causal Decision Theory and the EPR statistics conflict. We infer that anyone who fully accepts any of these three hypotheses has strong reasons to reject Causal Decision Theory. Finally, we extend the original construction to show that anyone who gives any of the three hypotheses any non-zero credence has strong reasons to reject Causal Decision Theory. However, we concede that no version of the Many Worlds Interpretation (Vaidman, in Zalta, E.N. (ed.), Stanford Encyclopaedia of Philosophy 2014) gives rise to the conflicts that we point out.  相似文献

Longitudinal studies have shown that preschool children’s diagnosis of Oppositional Defiant Disorder (ODD), Conduct Disorder (CD) and Attention-Deficit/Hyperactivity Disorder (ADHD) are likely to persist into school age. However, limited attention has been paid to instability of diagnosis. The aim of the present study, therefore, was to investigate both stability and change of ODD, CD and ADHD diagnosis in children aged 3.5–5.5 years. For diagnosing these disorders, a semi-structured diagnostic parent interview, i.e., the Kiddie-Disruptive Behavior Disorder Schedule (K-DBDS), was used at the first assessment and at follow-up assessments (9 and 18 months). Five diagnostic stability groups (chronic, partial remission, full remission, new onset, no diagnosis) were compared with regard to impairment and number of symptoms. Participants were referred preschool children with externalizing behavioral problems (N?=?193; 83 % male) and typically developing (TD) children (N?=?58; 71 % male). Follow-up assessments allowed to distinguish children belonging to the chronic group of ODD, CD or ADHD from those belonging to one of the remission groups. In addition, there was a substantial number of children with a new onset diagnosis. In conclusion, as a complement to studies showing stability of ODD, CD and ADHD diagnosis into school age, present findings point to changes of diagnosis in the preschool and early school period. Diagnostic reassessments therefore are needed in this age group.  相似文献

The third edition of theDiagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1980), outlines for the student what symptoms to consider when attempting to arrive at an accurate differential diagnosis of eight broad psychiatric categories. This paper describes a program developed to instruct a medical or graduate student in the science of such decision making.  相似文献

The Psychological Stress Evaluator (PSE) detects inaudible frequency changes in the human voice, and it is claimed that the pattern of these changes can provide a measure of psychophysiological arousal. A few studies have given some support to this hypothesis, but further clarifica tion is needed. One major technical problem in this research is that the traditional scoring esyStem is unreliable unless considerable numbers of scores are taken and averaged , The paper presents a conveniently brief scoring system which has fair reliahility, and which correlates significantly with a measure of Critical Flicker Fusion Threshold.  相似文献

Both perceived stress and negative recurrent thinking (rumination and worry) have been associated with depressive symptoms. However, no research to date has investigated the association between perceived stress and negative recurrent thinking. In the present study we aimed to explore whether perceived stress and negative recurrent thinking are associated and whether negative recurrent thinking moderates the relationship between perceived stress and depressive symptoms. A convenience sample of 273 undergraduate students completed the Perceived Stress Scale, the Ruminative Responses Scale-10, the Penn State Worry Questionnaire and the Hospital Anxiety and Depression Scale 2 weeks prior to sitting mid-year examinations. Correlation analyses showed that perceived stress, rumination and worry were positively and significantly associated with depressive symptoms and that perceived stress was positively and significantly associated with rumination and worry. A moderation analysis confirmed that negative recurrent thinking moderated the relationship between perceived stress and depressive symptoms. The implications of these findings are discussed.  相似文献

A model previously proposed for the size-weight illusion (Cross & Rotkin, 1975) was found unsatisfactory because the postulated volume parameter was not independent of the unit of measurement of weight and the model yielded a paradoxical prediction that the perceived heaviness of small objects should decrease as their weight increased. A new model was proposed based on Stevens and Rubin’s (1970) finding that heaviness functions are a family of con-verging power functions and some of Cross and Rotkin’s developments. The model was ex-amined by estimating its parameters from data previously reported by Cross and Rotkin, Stevens and Rubin, and Kolehmainen and Mikkonen (1970). The equations was found to fit each set of data well. Four independent estimates of a volume parameter of the model were in close agreement, .18, .21, .21, and .24, which is consistent with the model. nt]mis|This research was supported by Grants A0151 and A9582 from the National Research Council of Canada.  相似文献

Analysis of Eysenck Personality Inventory measures of personality and measures of mood obtained by the Nowlis Mood Adjective Check List revealed four main factors. Neuroticism was associated with a cluster of mood variables related to anxiety and depression and extraversion to a cluster related to self -confidence, but not to activation. Implications for the use of these measures in cognitive and other research are indicated.  相似文献

The purpose of this study was to document the relationship of parents' personal and marital adjustment to their own behavior as parents and the behavior of their children. A total of 31 families who had been referred for behavioral counseling regarding their male child's behavior problems were given a diagnostic battery which included home observations as well as administration to parents of the Minnesota Multiphasic Personality Inventory (MMPI) and the LockeWallace Marital Adjustment Test. Results revealed consistent negative relationships between marital satisfaction and the observed level of child deviance. Similarly, there were consistent negative relationships between marital satisfaction and the level of observed “negativeness” to the child. Analyses using the MMPI indicated that a large number of the fathers ' MMPI scales were related to child deviance, but this finding was not replicated for mothers. Several MMPI scales were related to marital satisfaction for both parents. These results are discussed in terms of their implications for the assessment and treatment of families with a problem child.  相似文献

This study was designed to investigate the role of sensory reinforcement in the motivation of self-stimulation. If self-stimulatory behavior is maintained by its sensory consequences, such as the proprioceptive, auditory, or visual stimulation it produces, then such behavior should extinguish when those sensory consequences are not permitted. The present study introduces a new procedure, Sensory Extinction, in which certain sensory consequences are masked or removed, to examine whether self-stimulation is operant behavior maintained by sensory reinforcement. The effectiveness of Sensory Extinction was assessed by a reversal design for each of three autistic children, and the results showed the following. First, self-stimulation reliably extinguished when a certain sensory consequence was removed, then increased when that consequence was permitted. This was replicable within and across children. Second, different Sensory Extinction procedures were required for different self-stimulatory behaviors, since the sensory reinforcers supporting them were idiosyncratic across children. Finally, regarding clinical gains, the data suggest that Sensory Extinction may be a relatively convenient and rapid alternative for the treatment of self-stimulation. The present findings extend the efficacy of extinction as a behavior-modification technique to instances in which the reinforcer is purely sensory. The implications of these results for the treatment of other forms of deviant behavior are discussed.  相似文献
