coser的角色類似模特兒，會將自己的成果照片供他人觀賞，同時又有觀眾會給予相關評價，以及來自廠商或原作設定的標準需要符合，故coser是否會因此改變自我的觀點？因此本研究旨在探討coser之身體意象和自我認同的現況與關係，以及探討不同個人背景因素之coser在身體意象與自我認同上的差異情形。本研究採「問卷調查法」，以立意取樣及滾雪球方式對coser進行取樣，共取得222份有效樣本。研究工具包含：「身體意象量表」、「自我認同量表」與「個人背景資料調查表」。所得資料以描述性統計、單一樣本t檢定、獨立樣本t檢定、單因子變異數分析、雪費事後檢定法、皮爾森積差相關及強迫進入法多元迴歸加以分析。本研究結果如下：
一、Coser之身體意象與自我認同皆高於中間值，表示coser對自己的身體意象及自我認同皆有較正向之評價。
二、 平均一年玩 cosplay的次數在身體意象及自我認同上皆有顯著差異，平均一年內玩cosplay的次數越多，對身體意象的滿意度越高，自我認同也較正向。
三、Coser之身體意象及自我認同為顯著正相關，表示coser之身體意象越正向，自我認同也越高。
四、Coser之「身體意象」與「玩cosplay的時間」對「自我認同」具有58 %的解釋力。
根據研究結果，建議coser在可以負擔的範圍內盡量多參與此活動，增加活動的頻率，能維持較正向的身體意象及自我認同。
Cosers are like models, they will show the photos taken to the public, and the audience will give them feedback. In addition, cosers have a certain appearance that needs to be met.
This study adopted snowball sampling and purposive sampling,222 valid samples were pbtained. Research instrument included "Personal Background Questionnaires", "Body Image Scale"and"Self-Identity Scale".
The data were analyzed by descriptive statistics, one-sample t-test, independent sample t-test, one-way ANOVA, Scheffe’s method, Pearson’s product-moment correlation, and multiple regression analysis. The results of this study are as follows:
1. The score of "body image" and "self-identity" are above average, which means cosplayers have more positive attitude toward their body image and self-identity.
2. Coser’s "Frenquency of cosplays in a year" shows significant difference in "body image" and "self-identity".
3. "Body image" and "self-identity" show significantly positive correlation.
4. Cosplayer's "Body image"and "length of playing cosplay" has 58% of variance to self-identity.
According to the results, it is recommended that
cosers can participate in cosplay as much as possible, and increase the frequency of participation in order to maintain positive body image and self-identity.
