Dance Imagery

AbstractGiven the differences between young dancers’ and adult dancers’ use of imagery, a valid and reliable questionnaire specific to young dancers was necessary. The current study is the first phase of a multi-phase study in the development of the Dance Imagery Questionnaire for Children (DIQ-C). Specifically, the purpose of this study was to establish content validity of the DIQ-C. This was achieved through the following three stages: (1) definition, item, and scale development, (2) assessment of item clarity and appropriateness via cognitive interviews, and (3) assessment of item-content relevance via an expert rating panel. Guided by previous qualitative research with young dancers, 46 items representing seven subscales (i.e., imagery types) were developed. The initial item pool was then implemented during cognitive interviews with 16 dancers (15 females; Mage=10.63, SD=1.82), which led to the removal of 13 items and the modification of 21 items. Consequently, the revised 33-item pool was then administered to an expert panel of four imagery researchers and four dance instructors to measure item-content relevance. This resulted in the removal of eight items, the revision of four items, and the merging of two subscales. Overall, the current study provides content validity evidence for a 25-item pool (representing five subscales) to be used in further development of the DIQ-C (i.e., identifying and establishing factor structure).

Abstract Purpose The purpose of the study was to validate the AQoL-8D questionnaire in the adult population of patients referred to an otolaryngology clinic. Methods AQoL-8D was translated into Polish. 463 patients (age18–80 years) with otolaryngological conditions were assessed with the AQoL-8D, SF-6D, and SWLS questionnaires. We investigated the item content-relevance, factor structure by means of Confirmatory Factor Analysis, corrected item-total correlations, Cronbach’s alpha, Pearson correlation of the AQoL-8D scores with results from SF-6D and from the SWLS questionnaires. Finally, ANOVA was used to test the AQoL-8D ability to group the HRQoL of patients in terms of their otolaryngological management type. Results The median score of item content-relevance was 5.0 for all AQoL-8D items. Confirmatory Factor Analysis revealed the following fit indices: Comparative Fit Index = 0.81; Tucker–Lewis Index = 0.80; and Root Mean Square Error of Approximation = 0.07. Cronbach's alpha for AQoL-8D dimensions ranged from 0.48 to 0.79. Mean item-total correlations over all dimensions, super dimensions, and the instrument overall were higher than 0.3. There was a significant Pearson correlation between the results obtained with AQoL-8D and SF-6D (r = 0.68), and with AQoL-8D and SWLS (r = 0.43). A one-way ANOVA showed a significant effect of management type on HRQoL as measured by AQoL-8D [F(4,458) = 6.12, p < 0.001] Conclusion AQoL-8D provides valid and reliable measures of HRQoL in patients undergoing otolaryngological treatment. Because it is a generic questionnaire, it is possible to make general comparisons of otolaryngology outcomes with those from other subspecialties.

Background: The objective of this qualitative methods study was to develop the domains and items to support the content validity for the Pediatric Quality of Life Inventory (PedsQL) Multiple Sclerosis Module for youth with pediatric-onset multiple sclerosis. Methods: A literature review of multiple sclerosis–specific questionnaires and clinical research was conducted to generate domains. An expert panel composed of 12 neurologists who were pediatric-onset multiple sclerosis specialists provided feedback on the conceptual framework. Focus interviews with 9 youth with pediatric-onset multiple sclerosis and 6 parents were conducted to develop the relevant domains and item content from the patient and parent perspective. In the cognitive interviews phase, 9 youth with pediatric-onset multiple sclerosis and 6 parents provided feedback on item content, relevance, importance, and understandability of the pediatric-onset multiple sclerosis–specific domains and items. The final interview phase with 5 youth with pediatric-onset multiple sclerosis and 5 parents comprised a pilot testing of the new PedsQL MS Module. Results: Eighteen domains were derived from the qualitative methods with item content saturation achieved at 100 items based on 40 interviews with 23 youth with pediatric-onset multiple sclerosis aged 10-21 years and 17 parents. The domains derived include general fatigue, sleep/rest fatigue, cognitive functioning, tingling sensations, numbness sensations, physical weakness, pain, speech, balance, fine motor, vision, urination, constipation, bowel incontinence, worry, communication, treatment, and medicines. Conclusions: Qualitative methods involving 23 youth with pediatric-onset multiple sclerosis and 17 parents in the domain and item development process support the content validity for the new PedsQL MS Module. Future plans include a national field test of the PedsQL MS Module scales and items.

Scanning tunneling microscopy (STM) has evolved rapidly in the past few years. Major developments have occurred in instrumentation, theory, and in a wide range of applications. In this paper, an overview of the application of STM and related techniques to polymers will be given, followed by a discussion of current research issues and prospects for future developments. The application of STM to polymers can be conveniently divided into the following subject areas: atomic scale imaging of uncoated polymer structures; topographic imaging and metrology of man-made polymer structures; and modification of polymer structures. Since many polymers are poor electrical conductors and hence unsuitable for use as a tunneling electrode, the related atomic force microscopy (AFM) technique which is capable of imaging both conductors and insulators has also been applied to polymers.The STM is well known for its high resolution capabilities in the x, y and z axes (Å in x andy and sub-Å in z). In addition to high resolution capabilities, the STM technique provides true three dimensional information in the constant current mode. In this mode, the STM tip is held at a fixed tunneling current (and a fixed bias voltage) and hence a fixed height above the sample surface while scanning across the sample surface.
