| Summary: | 碩士 === 國立政治大學 === 企業管理研究所 === 97 === The concept of consumption fantasy has continually been receiving attention and kept developing by researchers in relevant fields, but relevant research could only focus on concept development (Belk et al., 2003; Julia Lee, 2005) or specific groups with higher degree of fantasy (Martin, 2004) due to lack of instruments to measure fantasy. Research about consumption fantasy through quantitative method has been commenced after the first fantasy inventory was built by domestic researcher Huang I-tin (2006). Nevertheless, there is still room for further revision and improvement in the development process, test-retest reliability, criterion-related validity and the dimensions of fantasy inventory build by Huang I-tin. This study is aimed to access the traditional fantasy inventory and rebuild it into an inventory with better quality on reliability and validity.
The second edition of pretest questionnaire used by Huang I-tin was chosen to conduct subsequent development of dimension assessment, inventory purification, reliability and validity analysis to increase the quality of fantasy inventory. The face validity analysis was executed due to the discovery of unstable of inventory dimensions, the result unveiled that some items in some dimensions are hard to distinguish and some items do not satisfy the definitions of their dimensions. Referring to literatures and reassessing the purpose of fantasy inventory due to the need of rearrangement of dimensions in this inventory, “dimension-factor” matrix of design concept was initiated, and the first draft of revised fantasy inventory was developed after two panel discussions held on the revision and integration of old items extract from old fantasy inventory with new designed items. Once the fantasy inventory had been proved to have face validity via dimensional assessment, three small-scale surveys, in which the respondents are composed of students, were executed to develop the formal fantasy inventory through internal consistency reliability and exploratory factor analysis aimed to purify the draft of fantasy inventory. After the small-scale surveys, 200 general consumers were chosen to conduct formal questionnaire survey, which included reliability analysis, confirmatory factor analysis and criterion-related validity analysis, to build a fantasy inventory containing 19 Likert-type items. Overall, the Cronbach’s Alpha of this inventory is 0.90; test-retest reliability is 0.81. This inventory covers four dimensions: the distance of “Accessibility”, ”Pass Experience Relatedness”, the degree of “Fineness ”, and the degree of “Continuity”.
In addition, the degree of vividness of visual imagery is discovered to be the criterion of fantasy from literature review. By assessing criterion validity, the degree of vividness of visual imagery is confirmed to be fit for criterion of fantasy. Finally, for the test of thesis that older people have lower degree of fantasy; the result indicated that there’s no negative relation existing between the dimension of “experience-relativity” and the dimension of “the degree of fineness”.
