This article describes a multidimensional, multivariate, and multilevel approach to the assessment of nicotine withdrawal. In this prospective study, 70 adult smokers assigned to an active or placebo nicotine patch condition completed multiple daily assessments using an electronic diary. Average and individual growth curves were estimated for affective and nonaffective withdrawal symptoms. All symptoms but hunger increased significantly on the quit day and remained elevated for three weeks. Variability in symptom experiences across individuals increased from pre- to post-quit. Relations between symptom reports (e.g., negative affect or craving) and episodic events (e.g., stressful events or seeing someone smoke) changed from pre-quit to post-quit. Pre-quit increases in negative affect and quit-day increases in craving were inversely related to abstinence three months after the quit day, suggesting that anticipatory and immediate reactions to quitting influence success. 相似文献

We examine the nature of motor representations evoked during comprehension of written sentences describing hand actions. We distinguish between two kinds of hand actions: a functional action, applied when using the object for its intended purpose, and a volumetric action, applied when picking up or holding the object. In Experiment 1, initial activation of both action representations was followed by selection of the functional action, regardless of sentence context. Experiment 2 showed that when the sentence was followed by a picture of the object, clear context-specific effects on evoked action representations were obtained. Experiment 3 established that when a picture of an object was presented alone, the time course of both functional and volumetric actions was the same. These results provide evidence that representations of object-related hand actions are evoked as part of sentence processing. In addition, we discuss the conditions that elicit context-specific evocation of motor representations. 相似文献

To assess test-retest reliability scores on 16 balance tests of 21 individuals with Down syndrome whose ages ranged from 5 to 31 yr., participants performed a standing test on firm and soft surfaces with the eyes open and closed, the balance subset of the Bruininks-Oseretsky test, full turn, timed-up-and-go test, forward reach, and sit-to-stand. Each participant completed all 16 tests twice in one day and then again on a subsequent day for a total of 4 sessions. The interclass reliability correlation coefficients (ICC) value for each measure of balance varied considerably by age and sex. Based on having an ICC > .50, only 3 tests were reliable in young males and young females, whereas 5 tests could reliably be used in adult females and 9 tests could reliably be used in adult males. The results of this study raise suspicions as to the reliability of tests commonly used to assess balance and differences in reliability due to age and sex. Results of balance tests should be interpreted with caution in males and females with Down syndrome across the age span. 相似文献

This paper analyzes assault victims’ reactions over the course of two months. Specifically, reaction types are analyzed across four dimensions: behavioral changes, interpersonal difficulties, physical symptoms, and emotional responses. Initially, most rape victims report fairly high levels of disruption across three of the four reaction types, with some signs of recovery two months later. Patterns of reactions are also exhibited. At the two month follow‐up, behavioral changes, physical symptoms, and emotional responses have declined, while interpersonal difficulties have increased slightly. These data suggest that the present service delivery system of the rape crisis center may be problematic in that they offer only short‐term intervention. Some victims of rape may require a different type of service from such centers. 相似文献

Abstract The Views of Life Scale (VOLS) was designed to measure perception of well-being in three areas: inherent value of life, effective life management, and sense of health. Items were placed in these three categories by a team of advanced doctoral students; their overall agreement on item placement was 91.8%. These three categories became Subscales I, II and III of the total instrument. Seven hundred and thirty-two participants responded to the 42 item VOLS; subsamples of this group also took various other instruments with which the VOLS was being compared. Reliability assessment yielded very strong test-retest stability (I=0.80, II=0.87, III=0.76, Total=0.86) and high internal consistency (I=0.76, II=0.83, III=0.81, Total=0.91) for the VOLS measures. Relationships between the VOLS and other inventories provided consistent support for the convergent and divergent validity of the VOLS. An oblique rotation factor analysis produced five major quantitative clusters in the VOLS. There was considerable overlap between these factors and the original subscales. 相似文献
