Editors can lead researchers to confidence intervals, but can't make them think: statistical reform lessons from medicine 总被引:3,自引:0,他引:3
Since the mid-1980s, confidence intervals (CIs) have been standard in medical journals. We sought lessons for psychology from medicine's experience with statistical reform by investigating two attempts by Kenneth Rothman to change statistical practices. We examined 594 American Journal of Public Health (AJPH) articles published between 1982 and 2000 and 110 Epidemiology articles published in 1990 and 2000. Rothman's editorial instruction to report CIs and not p values was largely effective: In AJPH, sole reliance on p values dropped from 63% to 5%, and CI reporting rose from 10% to 54%; Epidemiology showed even stronger compliance. However, compliance was superficial: Very few authors referred to CIs when discussing results. The results of our survey support what other research has indicated: Editorial policy alone is not a sufficient mechanism for statistical reform. Achieving substantial, desirable change will require further guidance regarding use and interpretation of CIs and appropriate effect size measures. Necessary steps will include studying researchers' understanding of CIs, improving education, and developing empirically justified recommendations for improved statistical practice. 相似文献

A sex difference in security of infant attachment was found in a sample of 52 infant-mother dyads. The infants were enrolled in early care and education programs within a predominantly small-town geographic area in the southwest. Security of attachment was assessed using the Strange Situation procedure. Male infants (76%) were significantly more likely to be securely attached than female infants (39%). No other variables related to the infants' early care and education experience or mothers' age, race, marital status, and education were significantly associated with infants' attachment status. 相似文献

A new testing package, including apparatus and tasks, is described for the study of behavior of a variety of species in a variety of experiments. The package is described with respect to the kinds of comparative psychological investigations for which it is well suited. The preliminary data generated within this new testing paradigm demonstrate that the NASA/LRC Computerized Test System provides a flexible yet powerful environment for the investigation of behavioral and psychological processes. 相似文献

Two behavioral avoidance tests were administered, before and after in vivo exposure treatment, to 39 female patients with chronic and severe agoraphobia. The first test consisted of walking alone along a standard course covering several city blocks, and the second of entering and remaining in five different, individually selected phobic situations. Although significant improvement on the tests was observed in the sample as a whole, neither test had a high nosographic sensitivity (nearly two-thirds of the patients completed them initially) and subgroups of avoiders and nonavoiders, classified simultaneously on both tests, did not differ significantly in their clinical characteristics or response to treatment. The difficulty for the behavioral test to account for the majority of variance in phobic avoidance, and the severity of agoraphobia in general, is discussed with particular reference to the differences between the going to and the being in types of phobic situations and the essentially anticipatory nature of anxiety and fear.This research was supported by Grants MH40141 and MH34177 from the National Institute of Mental Health. 相似文献

A study was carried out to investigate whether supervisors of counsellors considered themselves to be clinically responsible for the work of their supervisees, what responsibilities they considered themselves to have for the counsellors' work, and how they managed their responsibilities. The purpose of the study was to enhance the counselling profession's understanding of the responsibility of supervisors and of the supervisory relationship. The study was confined to supervisors working in private practice. Ten experts in the field of counselling and supervision were interviewed, using a semi-structured questionnaire. The interviews were analysed using the 'constant comparative method'. They revealed that the participants would not use the term 'clinical responsibility' to describe their responsibilities. There were mixed views about the nature of the responsibility of the supervisor when supervising counsellors practising independently. The participants indicated a preference to supervise only the most experienced counsellors, with whose practice they were already familiar and in whose work they already had considerable confidence. None of the supervisors interviewed considered themselves to be legally responsible for the counsellors' work. All the participants were aware that the risks associated with counselling in private practice could be considerable and had an acute sense of responsibility for the content of the work. Reluctance to take action against supervisees who were in breach of the code of ethics was expressed. There was scepticism about the requirement for them to have supervision for their supervisory work. Implications for the practice of counselling supervision and for the profession are discussed. 相似文献

Differences in the personal nature of police officers as well as differences among the situational constraints due to assignments are considered in an examination of the occurrences of police involvement in shooting incidents. The Poisson and negative binomial models used in accident research are considered for representing the occurrence of shooting incidents. Data were gathered from incidents in a large metropolitan police department over a 34-month period and used to test the two models. Various analyses indicate a good Poisson fit. Implications of the data are discussed. 相似文献
