Background: The conventional question (CQ) on subjective well-being (SWB) is e.g. “How is life?”, with ratings between e.g. ‘Best’ and ‘Worst possible’. Disadvantages may be casualness of responses and biases of proximate, peer or cultural relativity. Alternatively, with Anamnestic Comparative Self-Assessment (ACSA), the scale anchors are the respondents’ self-defined memories of their best and worst periods in life. Thus ACSA uses life review and experiential scale anchors. Objective: To compare the validity, sensitivity and responsiveness of the CQ and ACSA. Method: ACSA and the CQ were administered in parallel to 2584 university-hospital patients suffering from a wide range of psychiatric and somatic diseases. Results: ACSA and CQ did not measure the same construct (r = 0.50). CQ ratings were almost normally distributed, whereas ACSA ratings were overall lower, and clearly positively skewed, suggesting greater sensitivity to the respondents’ diseased state. Contrary to CQ, ACSA ratings of critically ill patients with end-stage liver disease were very low. After life-saving liver transplantation, ACSA ratings increased significantly more than CQ ratings, suggesting better responsiveness of ACSA to objective change. Trait-like socio-demographic variables such as sex, age, and marital status influenced CQ, but not ACSA ratings. Conclusion: In between-subject studies, depending on one’s study objectives, ACSA should be considered as a complement or an alternative to conventional SWB instruments. The CQ is probably preferable when socio-demographic variables are study endpoints. In longitudinal or intervention studies and for intercultural comparisons, ACSA, which reduces the need for correction of several biases or confounders, seems more useful. 相似文献

Personality constructs, attitudes and other non-cognitive variables are often measured using rating or Likert-type scales, which does not come without problems. Especially in low-stakes assessments, respondents may produce biased responses due to response styles (RS) that reduce the validity and comparability of the measurement. Detecting and correcting RS is not always straightforward because not all respondents show RS and the ones who do may not do so to the same extent or in the same direction. The present study proposes the combination of a multidimensional IRTree model with a mixture distribution item response theory model and illustrates the application of the approach using data from the Programme for the International Assessment of Adult Competencies (PIAAC). This joint approach allows for the differentiation between different latent classes of respondents who show different RS behaviours and respondents who show RS versus respondents who give (largely) unbiased responses. We illustrate the application of the approach by examining extreme RS and show how the resulting latent classes can be further examined using external variables and process data from computer-based assessments to develop a better understanding of response behaviour and RS. 相似文献

There are a growing number of item response theory (IRT) studies that calibrate different patient-reported outcome (PRO) measures, such as anxiety, depression, physical function, and pain, on common, instrument-independent metrics. In the case of depression, it has been reported that there are considerable mean score differences when scoring on a common metric from different, previously linked instruments. Ideally, those estimates should be the same. We investigated to what extent those differences are influenced by different scoring methods that take into account several levels of uncertainty, such as measurement error (through plausible value imputation) and item parameter uncertainty (through full Bayesian IRT modeling). Depression estimates from different instruments were more similar, and their corresponding confidence/credible intervals were larger when plausible value imputation or Bayesian modeling was used, compared to the direct use of expected a posteriori (EAP) estimates. Furthermore, we explored the use of Bayesian IRT models to update item parameters based on newly collected data. 相似文献

In contrast to the original Implicit Association Test (IAT), the Single‐Target Implicit Association Test (ST‐IAT) measures the evaluation of a target object without the need to simultaneously evaluate a counter‐category. The present research investigates (a) whether position within a series of several ST‐IATs affects reliability and validity, and (b) whether the ST‐IAT exhibits adequate construct validity if the target objects are closely interrelated. We address these questions by taking five interrelated yet distinct political parties in Germany as an exemplary domain. The ST‐IAT reliably and validly assessed attitudes towards political parties (Study 1). Serial position effects did not affect the results. The ST‐IATs mostly captured a specific party evaluation and exhibited discriminant validity. At the same time, discriminant validity was limited among parties within one wing of the political left–right spectrum that underlies implicit and explicit party evaluations (Study 2). If used with caution, the ST‐IAT can be a valuable supplement to implicit measures in the case of multiple single‐target assessments. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Prosody or speech melody subserves linguistic (e.g., question intonation) and emotional functions in speech communication. Findings from lesion studies and imaging experiments suggest that, depending on function or acoustic stimulus structure, prosodic speech components are differentially processed in the right and left hemispheres. This direct current (DC) potential study investigated the linguistic processing of digitally manipulated pitch contours of sentences that carried an emotional or neutral intonation. Discrimination of linguistic prosody was better for neutral stimuli as compared to happily as well as fearfully spoken sentences. Brain activation was increased during the processing of happy sentences as compared to neutral utterances. Neither neutral nor emotional stimuli evoked lateralized processing in the left or right hemisphere, indicating bilateral mechanisms of linguistic processing for pitch direction. Acoustic stimulus analysis suggested that prosodic components related to emotional intonation, such as pitch variability, interfered with linguistic processing of pitch course direction. 相似文献

Forgiveness is often assumed to be adaptive for psychological adjustment following interpersonal transgressions. Three hundred and forty seven individuals who had experienced a recent interpersonal transgression were surveyed on four occasions over the course of six weeks. Forgiveness was assessed with scales measuring interpersonal avoidance and revenge motivation and psychological adjustment was assessed with scales measuring depression and rumination. Latent growth curve analyses showed that intraindividual changes in forgiveness were positively correlated with changes in adjustment. Latent difference score analyses indicated that adjustment predicted subsequent change in forgiveness, but that forgiveness did not predict subsequent change in adjustment. The results suggest that adjustment facilitates forgiveness, but not that forgiveness facilitates adjustment. 相似文献

Drawing on motivational approaches to emotion, the authors propose that the perceived change in spatial distance to pictures that arouse negative emotions exerts an influence on the significance of these pictures. Two experiments induced the illusion that affective pictures approach toward the observer, recede from the observer, or remain static. To determine the motivational significance of the pictures, emotional valence and arousal ratings as well as startle responses were assessed. Approaching unpleasant pictures were found to exert an influence on both the valence and the arousal elicited by the pictures. Furthermore, movement of pleasant or neutral pictures did not influence startle responses, while the second experiment showed that approaching unpleasant pictures elicited enhanced startle responses compared to receding unpleasant pictures. These findings support the view that a change of spatial distance influences motivational significance and thereby shapes emotional responses. 相似文献

In 2 studies, the authors explored preadolescent and adolescent use of personal homepages in relation to mastery and identity formation. In Study 1, the authors attempted to determine the prevalence of personal homepage and online journal (blog) construction among a random sample (N=500) of preadolescents and adolescents. Adolescents were more likely to create personal homepages or blogs than preadolescents. Creation was related to feelings of mastery, expressions of identity, and a means to socialize. In Study 2, the authors explored the relationship of homepages to mastery and identity formation by content analysis of a random sample of homepages. Results suggest children use personal homepages to express and explore their forming identities. 相似文献

The authors investigated the phenomenon that performance in an ongoing task declines when individuals must carry out a prospective memory (PM) task. This effect is referred to as the PM interference effect. The authors examined whether the PM interference effect differs between event-based and time-based PM tasks and whether it is increased among the elderly. The authors also investigated adult age differences in PM performance and the potential underlying mechanisms of the age deficits in PM. They found that the PM interference effect was greater in event-based than in time-based tasks. However, aging was not associated with an increase in PM interference effects. Age differences in PM performance were more exaggerated in time-based than event-based PM, but they were not mediated by age differences in traditional cognitive ability measures. In time-based PM, age showed a unique adverse effect even after controlling for the ability to externally monitor the time, leading to the possibility that aging disrupts time-based PM because of deficits in internally processing the time. 相似文献
