本研究旨在探討人格特質、Instagram 社群影像色彩特徵與飲食行為之關聯性。研究採問卷調查法蒐集資料,共取得182份有效樣本,並分析受試者 Instagram照片之 HSV色彩特徵。研究工具包含大五人格量表(BFI-10)與荷蘭飲食行為量表(DEBQ);資料分析方面,人格特質與飲食行為以簡單線性迴歸進行分析,社群影像色彩特徵則依三分位數分組,並以飲食行為歸類次數進行交叉表與卡方檢定。 研究結果顯示,盡責性與限制性飲食、神經質與情緒性飲食皆呈顯著正向關聯,外向性與外因性飲食之間則未達統計顯著。社群影像色彩特徵方面,僅色相(H)分組與飲食行為類型達顯著關聯,其中情緒性飲食與限制性飲食較多分布於色相高組,外因性飲食則較多分布於色相低組;飽和度(S)與明度(V)分組皆未達顯著。由上述結果可知,部分人格特質與特定飲食行為之間具有顯著關聯,而社群影像色彩特徵可作為探索飲食行為差異之輔助參考。本研究嘗試將社群影像色彩特徵納入飲食行為研究,補充過去多以問卷心理變項為主之研究取向。;This study examined the relationships among personality traits, Instagram image color features, and eating behaviors. Data were collected through a questionnaire survey from 182 valid participants, and the HSV features of their Instagram photos were analyzed. Personality traits and eating behaviors were assessed using the BFI-10 and DEBQ. Simple linear regression was used to test personality–eating behavior relationships, while HSV features were grouped into tertiles and examined using cross-tabulation and chi-square tests based on eating behavior classification frequencies. Conscientiousness was positively associated with restrained eating, and neuroticism was positively associated with emotional eating, whereas extraversion was not significantly associated with external eating. Among the HSV features, only hue was significantly related to eating behavior type. Emotional and restrained eating were more common in the high-hue group, while external eating was more common in the low-hue group. Saturation and value were not significant. These findings suggest that certain personality traits are associated with specific eating behaviors, while image color features may serve as supplementary indicators for exploring differences in eating behavior.
