A Comparison of Distractors for Controlling Distress in Young Children During Medical Procedures

Distraction is a strategy that has been shown to be effective and safe in the control of pain and distress. We assessed the utility of two simple distraction procedures for reducing children's pain and distress. Three conditions, control, brief film, and short story, were delivered during repeated medical procedures in a randomized sequence to eight young children with cancer. Scores on the Observational Scale of Behavioral Distress (OSBD-R) as well as observer ratings of overall behavioral distress showed that the short story procedure was more effective than either the control condition or the cartoon film. These results argue for the utility of simple parent–child interactive distraction tasks to ameliorate children's procedural distress.     

Extending Psychometric Norms for Pre-Cardiac Transplantation Evaluations: The Florida Cohort, 1990–1996

Multidisciplinary pre-cardiac transplantation evaluations determine an individual's ability to benefit from potential transplantation. Psychologists are routinely consulted to perform psychological evaluations and testing to examine the candidate's current functioning and to forecast future functioning in the event of transplantation. The establishment of appropriate norms for psychological tests is an ethical imperative to provide high quality psychological consultations that maximize the utility of information gathered. The purpose of this paper is to present pre-cardiac transplant norms for a battery of psychological tests in a large population of consecutive transplant candidates. Together with other recently published norms on alternative test batteries, these norms allow the transplant psychologist to select from a range of psychological tests that span multiple domains of critical importance including the affective, behavioral, coping, cognitive, and health related quality of life domains. These norms appear to set a standard of practice for the use of psychological tests by a consulting transplantation psychologist.     

Coping and the Job Demands-Control-Support Model: An Exploratory Study

The job demands-control-support model indicates job control and social support enhance coping with job demands. This proposition was tested, using a heterogeneous sample of 272 full-time workers. The results indicated a series of complex interactions among demands, control, support, and coping on psychological well-being. Overall, control and support appeared to increase the effectiveness of problem-focused coping and emotion-focused coping up to a threshold depending on job demands. The results indicate that beyond this threshold, these forms of coping become less effective. Control appeared to enhance moderate levels of appraisal and cognitive escape-focused coping, but not high levels of appraisal or cognitive escape-focused coping. Social support appeared to enhance high levels of appraisal-focused coping. The results indicate that including coping in empirical tests of the job demands-control-support model enhances its explanatory and predictive power.     

Facial reactions to different emotionally relevant stimuli

Facial EMG activity was measured from the Corrugator supercilii and the Zygomatic major muscle regions while 48 subjects were exposed to pictures of angry and happy facial expressions, snakes and flowers as well as low and high preference nature scenes. The valency perspective predicted that facial reactions should be related to the intensity of the positive and the negative valency of stimuli. The mimicking behavior approach predicted that facial reactions should only be reflected as a mimicking response to the facial stimuli, whereas the evolutionary:biological perspective predicted that the most clearcut positive and negative facial reactions should be evoked by facial stimuli and by snakes. In support of the latter perspective, the present results showed that angry faces and snakes evoked the most distinct Corrugator supercilii muscle response, whereas happy faces evoked the largest Zygomatic major muscle response.     

Parents of Special Needs Children Mastering the Job of Parenting

The purpose of this investigation was to learn how parents master the job of parenting children with special needs. Through collaborative interviews using qualitative research methods, this study taps into the stories of five veteran families who reflect on the many challenges they faced from difficult beginnings to years of day-to-day struggles, and how they managed these challenges. Guidelines for family practitioners, based on the results, are discussed.

The Perceived Stress Scale: Factor structure and relation to depression symptoms in a psychiatric sample

The present study sought to examine the factor structure and psychometric properties of the Perceived Stress Scale (PSS) when administered to psychiatric patients. We also examined predictive validity of the PSS by assessing the association between the Perceived Stress Scale and the Beck Depression Inventory. A heterogeneous sample of 96 psychiatric patients (48 men, 48 women) completed the Perceived Stress Scale (PSS) and the Beck Depression Inventory. Factor analysis of the PSS established that the scale consisted of two factors. The first factor was comprised primarily of items reflecting adaptational symptoms. In contrast, the second factor consisted of items reflecting coping ability. Both factors had an adequate degree of internal consistency. Finally, a series of regression analyses predicting depression found that both factors accounted for unique variance in depression scores in women, but only the first factor accounted for unique variance in men. It is concluded that the PSS is a multidimensional and internally consistent measure of perceived stress.This research was supported by Grant 410-91-1690 from the social sciences and Humanities Research Council of Canada as well as by grants from the Research and Program Evaluation Committee Brockville Psychiatric Hospital.     

The contexts of adolescents' chronic life stressors

Proposed and tested a model of the determinants of adolescents' chronic life stressors, consisting of sociodemographic, personal, and contextual stress and coping factors, using baseline and 1-year follow-up data from 259 adolescents who varied in their psychological and physical health. Concurrent regression analyses at Time 1 and at Time 2, and longitudinal regressions that controlled for the levels of chronic stressors 1 year earlier, showed that sociodemographic, personal, and contextual factors each made a significant contribution to predicting adolescents' ongoing stressors with their mother, father, siblings friends and classmates and teachers at school. Personal factors of an emotional temperament and low perceived self-worth, and contextual factors of more negative life events and fewer social resources, were related to more chronic stressors. Suggestions for further development of the model are discussed. This research was supported by the William T. Grant Foundation, NIAAA Grants AA02863 and AA06699, and Department of Veterans Affairs Medical and Health Services Research and Development Services research funds.

时序信息提取特点的实验研究

时距区分性理论认为提取时序信息是在包含一定项目的检索系中检索抽样的过程,通道因素应当对正确率和速度都产生影响.本文分别以英文字母和汉字为材料,对时序信息的提取特点作了两个实验研究.结果表明,只有材料的呈现顺序对时序信息提取的正确率和速度都有影响,通道因素只影响提取的正确率,而速度则未受其影响。显然,用时距区分性理论来说明时序信息提取特点是缺乏足够证据的.本文提出,对时序信息提取机制尚值得进一步研究.     

Facial reactions to facial expressions in subjects high and low in public speaking fear

This study investigated whether subjects high and low in public speaking fear react with different facial electromyographic (EMG) activities when exposed to negative and positive social stimuli. A High-fear and Low-fear group were selected by help of a questionnaire and were exposed to slides of angry and happy faces while facial-EMG from the corrugator and zygomatic muscle regions were measured. The subjects also rated the stimuli on different emotional dimensions. Consistent with earlier research it was found that Low fear subjects reacted with increased corrugator activity to angry faces and increased zygomatic activity to happy faces. The High fear group, on the other hand, did not distinguish between angry and happy faces. Rating data indicated that the High fear group perceived angry faces as being emotionally more negative. The present results are consistent with earlier studies, indicating that the facial-EMG technique is sensitive to detect differential responding among clinical interesting groups, such as people suffering from social fears.
