A brief assessment tool for body image in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) may adversely affect body image in multitude ways. Development and validation of a brief and valid SLE specific body image tool were undertaken. Eleven items were identified on interview of 21 SLE patients for the Body Image Lupus Scale (BILS v1.0). The tool was administered to 70 SLE patients. Based on analysis, feedback, and refinement of items, the final iteration BILS v1.2 with five items was administered to 233 SLE patients along with validated body image measures (Situational Inventory of Body Image Dysphoria and Body Image Quality of Life Inventory) and health-related quality of life measures for a subsample. The BILS scores' had an internal consistency reliability of .94. It correlated with both the referent body image measures, and with health-related quality of life. It differentiated participants by health status and disease activity. Test-retest reliability estimates exceeded .90. These results support the psychometric properties of BILS.     

Selling and Sales Management in Action: The Sales Force's Role in International Marketing Research and Marketing Information Systems

Many companies resist global markets because of seemingly insurmountable problems with these markets. Salespeople are often used successfully to gather market information. There is a wealth of market data that can be collected by a company's international sales force and distributors' sales force which can prove to be valuable in surmounting cultural and marketing barriers associated with global markets. The current paper discusses how and with what success U.S. multinational companies are using their international sales forces in gathering international marketing research data.     

The Parentification Inventory: Development,Validation, and Cross-Validation

Abstract

This study hypothesized that subjects who strongly endorse unrealistic beliefs about intimate relationships would score higher on a measure of exposure to popular romantic media than subjects who do not. The relationship between exposure to media and satisfaction with one's current intimate relationship was also explored. Results for the 109 adult subjects support the hypothesis (r=.18, p<.05). There was also a trend for married women who were more exposed to the popular romantic media to be less satisfied with their current intimate relationships (r=? .26, p<.10). These results would seem to have significant psychological and social implications.     

I Knew It All Along,Unless I Had to Work to Learn What I Know

After receiving knowledge regarding some topic, people usually overestimate their prior topic knowledge. Two experiments investigated whether people would claim less prior knowledge if they worked to earn their present knowledge. In Study 1, students finishing a psychology course claimed less precourse psychology knowledge if they reported devoting more effort toward the course. In Study 2, the knew-it-all-along effect was stronger for participants who were simply given the answers to questions than for participants who studied for 20 minutes to learn the answers. Both cognitive and motivational factors can account for the observed effects of effort investment on retrospective knowledge judgments.     

The Effects of Time and Distance on Accuracy of Target-Directed Locomotion

Dual adaptation to different amounts or directions of prismatic displacement, or both, can be acquired and maintained with little mutual interference. Associative recalibration of the regional task- or workspace, contingent on differentiation of distinguishing sensory information, can explain such adaptation. In contrast, nonassociative realignment restores dimensional mapping among spatial representations. Methods for measuring the separate contributions of those 2 kinds of prism adaptation are identified in the present article. On the basis of a critique of dual-adaptation studies, the authors suggest that recalibration can explain the data but that the method used in those experiments confounded realignment and might have obscured the effectiveness of dual-calibration training.

The Coding of Location

One prediction of the recent target hypothesis for movement control (MacNeilage, 1970; Russell, 1976) holds that location reproduction is not solely dependent upon stored kinesthetic information. Three experiments were performed to test this prediction by requiring the subject to reproduce the location with the limb opposite to the one used for criterion production. This switched-limb procedure was assumed to force the subject to rely upon more abstract information rather than the kinesthetic cues of the criterion movement. With movement direction invariant, switched-limb reproduction was equal to same-limb reproduction. The alteration of movement direction hampered switched-limb reproduction but same-limb reproduction was not greatly affected. These findings gave some support to the target hypothesis but suggested that the context of the movement may affect the potency of the location code. Implications of the switched-limb technique for future research were briefly discussed.     

Distance and Movement Time Effects on the Timing of Agonist and Antagonist Muscles

The experiment examined the effects of movement time (MT) and distance on the timing of electromyographic (EMG) activity from an agonist and antagonist muscle during rapid, discrete elbow movements in the horizontal plane. According to impulse-timing theory (Wallace, 1981) MT, not distance moved, should have a pronounced effect on the timing of EMG activity (duration of initial agonist and antagonist burst and time to onset of initial antagonist burst). The levels of MT were 100 and 160 msec and the levels of distance were 27° and 45° of elbow flexion. In general support of impulse-timing theory, the results of the three EMG timing measures showed that MT had a more pronounced effect on these measures than distance. In addition, the timing of EMG activity in relation to total MT remained fairly consistent across the four MT-distance conditions.     

Memory and Perceptual Trace Development in Ballistic Timing

Adams’ (1971) closed-loop theory holds that memory and perceptual trace development is a function of the amount of practice with knowledge of results. If knowledge of results is withdrawn before these two memory states are strong performance will worsen, but after substantial practice performance can be maintained and evaluated in the absence of knowledge of results. To test the first prediction, three independent groups were given varying amounts of KR trials prior to early knowledge of results withdrawal. Subjects attempted to produce a 24.13-cm movement in exactly 150 msec. Memory and perceptual trace performance (as reflected in mean absolute and mean absolute estimated error, respectively) were dependent on the amount of knowledge of results practice, and the memory and perceptual trace remained reasonably strong during late knowledge of results withdrawal.
