Alief——影响心血管康复的潜在心理状态

心血管康复是涉及医学评价、处方运动、心血管危险因素矫正、教育、咨询和行为干预等的长期综合治疗程序,以改善心血管病的生理和心理状态,减少再次心肌梗死和猝死的危险,控制心血管症状,稳定或逆转动脉硬化过程和改善患者的心理和职业状态。心血管康复干预具体包括药物治疗、行为干预和心理介入等治疗。其中涉及一系列的心理-行为现象及概念。最近,心理医学领域提出了介于信念和想象的状态——Alief,这一具象派状态可以很好地解释与心血管康复相关的一些心理-行为现象,本文就此作一论述。     

Predicting Successful Employment in the Community for People with a History of Chronic Mental Illness

Much work has been done to prepare people with a history of chronic mental illness for vocational placement. Evaluation tools can select some who are likely to be successful in competitive or sheltered work. Many whose psychiatric disability is so severe it interferes seriously with their capacity for work have need for more pre-vocational or vocational skills training. A literature survey shows many programs designed to help this population but little specific outcome data. Other articles state the need for empirical research. With limited funds and a large underserved population, further research is important.

Active Recreation and Well-Being: The Reconstruction of the Self Identity of Women With Spinal Cord Injury

This qualitative study obtained the viewpoints of four women with spinal cord injury about the meaning of active recreation in their lives. Using the constant comparison method, common points of view were revealed within the narratives, leading to the finding that active recreation contributed to a positive self-concept. This facilitated the reconstruction of participants' identities as fit, confident, and social women actively engaged in their communities. Since participation in active recreation was found to be important to the self-identity of women who value physical activity, integrating this role into occupational therapy can facilitate the recovery of a desired self.     

Fractioned Reaction Ttme in Power-Trained and Endurance-Trained Athletes under Conditions of Fatiguing Isometric Exercise

Fractionated knee extensor and plantar flexor reaction time (RT) components were assessed in a group of eight weightlifters and eight long distance runners. Following a 4-day period of baseline stabilization for each muscle group, a 50% maximal voluntary contraction (MVC) holding-time exercise was administered. Results showed that the runners had longer premotor times (PMT) than the weightlifters in the knee extensors, but had much faster PMTs than the lifters in the plantar flexor condition. Compared to previously reported investigations using non-athletes, the data for the present sample of athletes indicated faster total reaction times (TRT) in both the knee extensors and the plantar flexors. A resistance of 15% MVC applied during the RT task resulted in a lengthening of the motor time (MT) component in both groups prior to exercise. However, while knee extensor resisted motor time was lengthened by the exercise task, no such lengthening occurred in plantar flexor resisted RT. It is concluded that power-trained and endurance-trained athletes exhibit differences in response to a fractionated RT task, under both baseline and fatiguing exercise conditions.     

Effects of Gradual Versus Sudden Training on the Cognitive Demand Required While Learning a Novel Locomotor Task

The cognitive demand required for a range of locomotor tasks has been described for a variety of populations. However, the effect of different training strategies on the cognitive demand required while learning novel locomotor tasks is not well understood and may inform physical rehabilitation. The authors examined whether two training strategies, gradual and sudden training, influenced the cognitive demand required while practicing a novel locomotor task, asymmetric split-belt treadmill walking. Simple reaction times and whole-body kinematics were recorded throughout practice. Gradual training resulted in significantly lower reaction times during much of training, suggesting that gradual training is less cognitively demanding than sudden training, possibly due to a reduction in error feedback or movement planning demands.     

Psychiatric rehabilitation of schizophrenia: Unresolved issues, current trends, and future directions

Psychiatric rehabilitation refers to a treatment philosophy and to a set of assessment and treatment techniques designed to reduce disability and maximize environmental adaptation. The field of psychiatric rehabilitation of schizophrenia is now well developed, and successful interventions exist for teaching many essential community-living skills and for promoting maintenance and generalization of these gains. Recent developments include the creation of new skills-training interventions and cognitive rehabilitation techniques and improvements in the delivery of vocational and substance abuse treatments. As a field, psychiatric rehabilitation is continuing to develop in a manner that is responsive to perceived treatment needs, shortcomings of existing interventions, and developments in related fields (e.g., social psychology, neuroscience of schizophrenia). Some of these developments in theory and research point to areas of conceptual/theoretical weaknesses in existing treatments and assessment measures and suggest directions for further development. This article reviews the current status of a number of areas within the psychiatric rehabilitation of schizophrenia, highlighting future needs.     

Event-Based Prospective Memory in Children with Sickle Cell Disease: Effect of Cue Distinctiveness

Event-based prospective memory (EB-PM) is the formation of an intention and remembering to perform it in response to a specific event. Currently, EB-PM performance in children with sickle cell disease (SCD) is unknown. In this study, we designed a computer-based task of EB-PM; No-Stroke, Silent-Infarct, and Overt-Stroke groups performed significantly below the demographically similar control group without SCD. Cue distinctiveness was varied to determine if EB-PM could be improved. All groups, with the exception of the Overt-Stroke group, performed significantly better with a perceptually distinctive cue. Overall, these results suggest that EB-PM can be improved significantly in many children with SCD.     

An Evaluation of the Reliability and Validity of the Self-Appraisal Questionnaire (SAQ) in South African Context

The Self-Appraisal Questionnaire (SAQ: Loza, 2005) is a self-report questionnaire designed to assist with the prediction of violent and nonviolent recidivism among correctional populations. Use of scale could help in the assessment of risk and the identification of factors that could be addressed by programming or other intervention to reduce recidivism risk. Evidence for use of the SAQ in South African settings is needed. The SAQ was administered at two separate occasions and a week apart to a total of 125 male offenders in South Africa to evaluate its psychometric properties. Scores from the SAQ were reliable with South African inmates.     

Some Physiological Concomitants of Pursuit Rotor Performance and Reminiscence

A frustration theory of pursuit rotor performance and reminiscence has previously been presented (Costello, 1967; Costello & Discipio, 1967). The theory was reformulated in terms of arousal theory and the following hypotheses were tested: (1) an inverted “U” relationship exists between level of arousal and performance level; (2) reminiscence results when S during the rest period moves closer to his optimum level of arousal; (3) massed practice produces a higher level of arousal than spaced practice; (4) experimental conditions producing a high drive state will also increase his arousal level. Findings in line with these hypotheses were found for EMG measures but not for GSR and pulse rate. In view of what appears to be the task-specific nature of the physiological results it was concluded that there was no particular advantage in reformulating the frustration theory in terms of arousal theory.
