本研究以台灣地區所有特殊教育學校的學生家長為研究對象，充分調查感激在關係行銷中的角色，尤其探討關係行銷中關係利益、教師專業、及親師溝通這三個變項對家長感激的影響，並討論家長感激與家長忠誠度的關聯性。本研究採問卷調查法，並採立意抽樣的方式進行問卷調查，回收有效問卷410份，以結構方程模式（SEM）進行潛在變項間的路徑分析。本研究主要發現為：（1）影響家長感激的具體原因為關係利益、教師專業及親師溝通，且此三變項對於家長感激皆有正向的影響；（2）家長感激並非只產生正向情緒－回報感，亦會產生負向情緒－罪惡感；（3）家長感激會直接正向的影響家長忠誠度；（4）正向情緒－回報感會正向影響家長的忠誠度，但負面情緒－罪惡感對家長的忠誠度卻沒有顯著影響。
