本研究擬以心情修復 (mood repair theory)與自我控制 (self-control theory)理論之觀點，探討員工在職場中吃點心的前因變數、中介機制、干擾效果與後果變數。本研究採經驗抽樣法，於兩週內連續施測10個工作天；每日共施測2次，分別
於下午與下班時段收集資料，有效配對180位員工，共1298筆每日有效資料。經多層次路徑分析：一、每日初始負向心情會透過提升享樂動機，促使員工食用不健康的點心，且個人對享樂型食物的偏好會增強前述關係；二、雖然每日情緒型工作需求會提升每日自我耗竭感，但不會因此尋求健康點心來補充個人資源；三、食用不健康點心可提升後續正向心情，食用健康點心則可提升後續活力狀態。

Based on the mood repair and self-control perspectives, we develop an integrative model that explored the antecedents, mechanisms, boundary conditions, and consequences of snacking at work. We collected daily data twice (i.e., the afternoon and evening surveys) for two weeks, resulting in 1,286 matched daily responses from 180 employees. The results of multilevel path analyses showed that: (a) daily activating negative moods increase unhealthy snacking at work via enhanced hedonic motive, and employees’ preference to eat palatable foods can strengthen such positive indirect effect; (b) although daily emotional job demands increase daily ego-depletion, the
depleted states did not predict healthy snacking at work; (c) daily unhealthy snacking increases employees’ subsequent positive moods, whereas healthy snacking increases their subsequent vigor.
