For questionnaires with two answer categories, it has been proven in complete generality that if a minimal sufficient statistic exists for the individual parameter and if it is the same statistic for all values of the item parameters, then the raw score (or the number of correct answers) is the minimal sufficient statistic. It follows that the model must by of the Rasch type with logistic item characteristic curves and equal item-discriminating powers.This paper extends these results to multiple choice questionnaires. It is shown that the minimal sufficient statistic for the individual parameter is a function of the so-called score vector. It is also shown that the so-called equidistant scoring is the only scoring of a questionnaire that allows for a real valued sufficient statistic that is independent of the item parameters, if a certain ordering property for the sufficient statistic holds. 相似文献

Abstract : A Lutheran bioethics must rest on a reconstructed version of Martin Luther's ethics. In the article it is shown that this ethics is Christian in that it has faith in Jesus Christ as its source. But the ethics of neighbor love is practiced in the secular world where it to some extent corresponds with natural law ethics. A Christian believer acts ethically both as an individual and as a citizen. Against the background of this understanding of Lutheran ethics, the position of Ted Peters and Gilbert Meilaender on genetics and stem cells is presented and criticized. One conclusion is that there is no Lutheran doctrine on the status of the human embryo. 相似文献

Since 1998, soldiers deployed to war zones with the Danish Defense (≈31,000) have been invited to fill out a questionnaire on post‐mission reactions. This provides a unique data source for studying the psychological toll of war. Here, we validate a measure of PTSD‐symptoms from the questionnaire. Soldiers from two cohorts deployed to Afghanistan with the International Security Assistance Force (ISAF) in 2009 (ISAF7, N = 334) and 2013 (ISAF15, N = 278) filled out a standard questionnaire (Psychological Reactions following International Missions, PRIM) concerning a range of post‐deployment reactions including symptoms of PTSD (PRIM‐PTSD). They also filled out a validated measure of PTSD‐symptoms in DSM‐IV, the PTSD‐checklist (PCL). We tested reliability of PRIM‐PTSD by estimating Cronbach's alpha, and tested validity by correlating items, clusters, and overall scale with corresponding items in the PCL. Furthermore, we conducted two confirmatory factor analytic models to test the factor structure of PRIM‐PTSD, and tested measurement invariance of the selected model. Finally, we established a screening and a clinical cutoff score by application of ROC analysis. We found high internal consistency of the PRIM‐PTSD (Cronbach's alpha = 0.88; both cohorts), strong item‐item (0.48–0.83), item‐cluster (0.43–0.72), cluster‐cluster (0.71–0.82) and full‐scale (0.86–0.88) correlations between PRIM‐PTSD and PCL. The factor analyses showed adequate fit of a one‐factor model, which was also found to display strong measurement invariance across cohorts. ROC curve analysis established cutoff scores for screening (sensitivity = 1, specificity = 0.93) and clinical use (sensitivity = 0.71, specificity = 0.98). In conclusion, we find that PRIM‐PTSD is a valid measure for assessing PTSD‐symptoms in Danish soldiers following deployment. 相似文献

Time-out (TO) is one of the most common and effective disciplinary tactics used to address problem behavior; however, parents rate TO as one of the least useful behavior modification techniques. This may be due to a discrepancy between empirically supported TO procedures and how mothers are actually conducting TO. Fifty-five mothers were asked to define TO, provide information on how they conduct TO, and identify errors in TO procedures. Results indicate that maternal knowledge and implementation of TO differs considerably from the empirical ideal, potentially impacting the utility and frequency of TO usage in the home to address child problem behaviors. 相似文献

Can we see the expressiveness of other people's gestures, hear the intentions in their voice, see the emotions in their posture? Traditional theories of social cognition still say we cannot because intentions and emotions for them are hidden away inside and we do not have direct access to them. Enactive theories still have no idea because they have so far mainly focused on perception of our physical world. We surmise, however, that the latter hold promise since, in trying to understand cognition, enactive theory focuses on the embodied engagements of a cognizer with his world. In this paper, we attempt an answer for the question What is social perception in an enactive account? In enaction, perception is conceived as a skill, crucially involving action (perception is action and action is perception), an ability to work successfully within the set of regularities, or contingencies that characterize a given domain. If this is the case, then social perception should be a social skill. Having thus transformed the question of what social perception is into that of what social skill is, we examine the concept of social contingencies and the manner in which social skills structure—both constrain and empower—social interaction. Some of the implications of our account for how social and physical perception differ, the role of embodiment in social interaction and the distinction between our approach and other social contingency theories are also addressed. 相似文献

Religion and spirituality are resources regularly used by patients with cancer coping with diagnosis and treatment, yet there is little research that examines these factors separately. This study investigated the relationships between religious practice and spirituality and quality of life (QoL) and stress in survivors of breast cancer. The sample included 130 women assessed 2 years following diagnosis. Using hierarchical multiple regression analysis, the authors found that spiritual well‐being was significantly associated with QoL and traumatic stress, whereas religious practice was not significantly associated with these variables. The results suggest that it may be helpful for clinicians to address spirituality, in particular with survivors of breast cancer. 相似文献

This study obtained feedback from intimate partner abuse survivors (N = 104) regarding helpful and unhelpful aspects of therapy. The survivors’ narrative accounts and answers to quantitative questions were subjected to quantitative and qualitative analysis. Results suggest that survivors sought therapy to understand themselves and the abuse they endured. Clinicians’ diagnoses of codependency or assertions that survivors chose the relationship weakened the therapeutic alliance and reduced the perceived helpfulness of therapy. 相似文献

Kersten et al (1997 Perception 26 171-192) found that the perceived motion of an object in a 3-D scene was determined by the motion of a shadow. In the present study, we compared the effect of a shadow to that of a second object on the ground in determining the perceived position in depth of a floating object in both dynamic and stationary scenes. Changing the second (lower) object from textured to dark increased the influence of the second object on the judged position of the first object. Giving the second object zero thickness had this effect only if it was also dark. Variations in the height of the floating object were important with a second object but not with a shadow, in motion scenes. With alternative shadows present, the position of the floating object was determined primarily by matching speeds, with matching sizes as a secondary factor. These results show some similarities but important differences between the effect of a second object and that of a shadow. 相似文献

This prospective, naturalistic study evaluated the practice and effectiveness of an outpatient group therapy program following day treatment for patients with personality disorders (PDs). One hundred and eighty-seven patients (86% patients with PDs and 14% with no PDs), were treated in outpatient psychodynamic group therapy. Outcome was assessed by Global Assessment of Functioning, Symptom Check List 90-R, and Inventory of Interpersonal Problems-Circumplex, short version, at admission and discharge from day treatment, and at the end of outpatient group therapy. Average length of outpatient therapy was 24 months. Forty-three percent terminated in an irregular manner. Outcome of the continuation therapy was satisfactory for patients without PDs. For PD patients, the improvement from the day treatment was maintained during outpatient therapy, but further improvements were modest for symptoms and interpersonal distress, somewhat better for global functioning. Implications for further treatment development are discussed. 相似文献
