This study examined the factor structure, validity, and reliability of the Fear Questionnaire in Hong Kong. The sample consisted of 226 college students who were ethnic Chinese and they came from different parts of Hong Kong. Exploratory factor analysis produced three meaningful factors. Confirmatory factor analysis supported the three-factor model of Marks and Mathews (1979) in the present sample of subjects. Findings also showed that the Fear Questionnaire was both reliable and valid. Limitations of the study and implications for future research in this area were discussed. In particular, the need to assess the cross-cultural application of the Fear Questionnaire was stressed.This research project was supported by the Research and Conference Grants of the University of Hong Kong. 相似文献

Researchers conducting longitudinal studies with children or adults are inevitably confronted with problems of attrition and missing data. Missing data in longitudinal studies is frequently handled by excluding from analyses those cases for whom data are incomplete. This approach to missing data is not optimal. On the one hand, if data are missing at random, then dropping incomplete cases ignores information collected on those cases that could be used to improve estimates of population parameters (e.g., means, variances, covariances, and growth rates) and improve the power of significance tests of statistical hypotheses. On the other hand, if data are not missing at random, then dropping incomplete cases leads to biased parameter estimates and hypothesis tests that may be internally and externally invalid. This study uses three years of follow-up data from a longitudinal investigation of neuropsychological outcomes of cancer in children to demonstrate the problems presented by missing data in repeated measures designs and some solutions. In evaluating potential biasing effects of attrition, the study extends previous research on neuropsychological outcomes in pediatric cancer by inclusion of patients whose disease had relapsed, and by comparison of surviving and nonsurviving patients. Although the data presented have specific relevance to the study of neuropsychological outcome in pediatric cancer, the problems of missing data and the solutions presented are relevant to a wide variety of diseases and conditions of interest to researchers in child and adult neuropsychology. 相似文献

We measured depressive symptomatology of 134 outpatient veterans treated within a Behavioral Medicine Clinic utilizing three reliable instruments with depression subscales: Minnesota Multiphasic Personality Inventory (MMPI), Derogatis Stress Profile (DSP), and Symptom Checklist 90—Revised (SCL-90-R). Results indicate that although the instruments correlate significantly, they differ in sensitivity to depression and are clinically discordant. The MMPI classified a substantially higher number of patients as depressed than either the DSP or SCL-90-R. The present study argues that the discrepancy in clinical concordance and sensitivity of the three depression scales has considerable implications for psychologists concerned with the assessment and treatment of depression. 相似文献

Urinary incontinence (UI) is a disorder receiving little attention from clinical health psychologists. This paper establishes the importance of addressing the issue of UI within the clinical and research practices of clinical health psychologists. Over 10 million Americans suffer from loss of bladder control. Incontinence affects over half of older individuals in long-term care institutions, about one-third of hospitalized elderly, and up to 30% of Americans over the age of 60 living at home. Because of social stigma and misconceptions attached to urinary incontinence, it is estimated that less than half of those affected see a physician about their condition. Since UI is generally associated with medical, social, psychological, and economic consequences, a multidisciplinary perspective is important because these factors are integral in the selection of appropriate treatment. Definitions of UI, its incidence and costs, and brief reviews of treatment and management techniques are presented. Psychological sequelae and treatments are presented as a foundation for developing further treatment and research approaches. Guidelines for collaboration and consultation by clinical health psychologists with medical professionals in the area of UI are also discussed. 相似文献

In the present experiment we report effects of cerebral asymmetry, or laterality, during classical conditioning to facial
emotional stimuli. Twenty-five female subjects were presented with slides of a happy face in one visual half-field (VHF),
and simultaneously a slide of an angry face in the other VHF, followed by shock as the unconditioned stimulus (UCS). To control
for effects of sensitization, a new stimulus, never associated with the UCS, was introduced in the extinction phase. Dependent
measures were phasic heart rate responses (HR) and skin conductance responses (SCR). The HR results showed a significant right
hemisphere effect for the CS-UCS association, that was not attributable to UCS sensitization. No significant effects were
found for the SCRs. The basic HR finding was a right hemisphere superiority for learning of a conditioned association. 相似文献

Multivariate effects of demand characteristics on the analogue assessment of heterosocial competence
The present study assessed the effects of a contextual demand manipulation (pretreatment assessment versus experiment) and an instructional demand manipulation (high demand for competent behavior versus neutral demand) on the analogue assessment of heterosocial competence. Also assessed was the interaction between each demand manipulation and subject characteristics (high-frequency dating/low heterosocially anxious versus low-frequency dating/high heterosocially anxious college males). Students were assigned randomly to one of four groups receiving differential information and instructions. Students completed a battery of five standard paper-and-pencil questionnaires, responded out loud to 10 taped social situations, and conversed with a female confederate while being videotaped for five minutes. Multivariate analyses revealed highly significant differences between subject groups and between contextual manipulation groups. Univariate analyses revealed that only 3 of the 16 dependent measures, including 2 of the self-reports, were significantly affected by the contextual demand. Results are discussed in light of previous studies of phobic behavior and social skills. Various avenues for future research were presented. 相似文献

An assessment instrument is presented for the evaluation of the quantity and quality of dyadic interaction, as well as for the daily recording of behaviors presented and omitted which influence marital satisfaction. Comparison of data from ten happy couples and from ten couples entering therapy indicated two distinct dysfunctional patterns among distressed couples, with significantly different patterns of time-together and positive/negative ratios differentiating the happy versus therapy groups. Independent behavioral recording for 14 consecutive days significantly increased husband-wife agreement on a traditional adjustment questionnaire without significantly increasing or decreasing the level of satisfaction being assessed. There was no difference between groups as to interspousal agreement on amount of time together. However, the happy couples agreed on daily quality ratings of the 72 15-minute segments significantly more often than did the distressed couples. Couples at the extremes of the happy-distressed continuum reported rewarding and punishing, respectively, in response to the partners presence, regardless of behaviors emitted. Midrange happy couples defined "pleasant" as positive behaviors presented; midrange distressed couples defined "pleasant" as negative behaviors omitted. Theoretical and clinical implications of behavioral analysis of sequential patterns are discussed. 相似文献

Various statistics have been proposed as standard methods for calculating and reporting interobserver agreement scores. The advantages and disadvantages of each have been discussed in this journal recently but without resolution. A formula is presented that combines separate measures of occurrence and nonoccurrence percentages of agreement, with weight assigned to each measure, varying according to the observed rate of behavior. This formula, which is a modification of a formula proposed by Clement (1976), appears to reduce distortions due to "chance" agreement encountered with very high or low observed rates of behavior while maintaining the mathematical and conceptual simplicity of the conventional method for calculating occurrence and nonoccurrence agreement. 相似文献
