Measuring control appraisals in chronic pain.
ABSTRACT Research has established a positive association between appraisals of control over pain and indexes of adaptive psychologic and physical functioning among persons with chronic pain. A number of measures of control appraisals have been used in the research literature. The current study sought to determine the number of factors or dimensions embedded in these commonly used measures of pain control appraisal. The study also sought to determine the association between the control appraisal construct(s) and measures of patient functioning. Two hundred fifty-two persons with chronic pain completed a questionnaire packet that included multiple measures of control appraisals. A factor analysis resulted in 6 factors: 1 factor representing beliefs about control over life in general, 1 representing perceived control over the effects of pain on one's life, and remaining 4 factors that appear to be more closely tied to perceived control over pain itself. Consistent with previous research, control appraisals made a significant contribution to the prediction of functioning (depression, disability, and pain interference). Most importantly, perceived control over the effects of pain on one's life and perceived control over life in general were more strongly associated with functioning than perceptions of control over pain itself.

ABSTRACT: In this work a new exact formula for determining the substrate resistance and capacitance is presented. For the formula analytical results of the Laplace equations of equivalent problems are exploited. Both simulation and measurement data are utilized in order to show the validity of the proposed formula. The measurement data are obtained from a fabricated test chip. The results show that the proposed method succeeds in computing the substrate resistance.Design & Technology of Integrated Systems in Nanoscale Era (DTIS), 2011 6th International Conference on; 01/2011

ABSTRACT: Prior studies found a range of psychological factors related to the perception of pain, maintenance of pain and disability. The aim of this study was to investigate the role of pain fear-avoidance and pain acceptance in chronic pain adjustment. The influence of two diathesis variables (resilience and experiential avoidance) was also analyzed. The sample was composed of 686 patients with chronic spinal pain. Structural equation modelling analyses were used to test the hypothetical model. Experiential avoidance was associated with pain fear-avoidance, and resilience was strongly associated with pain acceptance. Pain acceptance was negatively associated with negative mood, functional impairment and pain intensity. However, pain fear-avoidance was positively and significantly associated with negative mood but had no association with pain intensity. There was a path from functional impairment to pain fear-avoidance. Resilience and experiential avoidance appear as variables which could explain individual differences in pain experience.Annals of Behavioral Medicine 04/2014; 48(3).
