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.
