在人際互動的應對進退之間拿捏分寸，是華人社會中一門巧妙而高深的藝術。雖然拿捏看似一個重要的適應能力，然而，相關研究卻指出，拿捏不必然有助於提升個體的心理適應，也可能反過來造成個體的心理壓力。因此，本研究指出僅僅是注重行為上「怎麼做」是不夠的，更重要的是行為背後的思維模式，並主張具有中庸思維的拿捏行為才有利於個體的心理適應。研究一與研究二皆著眼於人際衝突情境中的拿捏行為，前者探討個體在情緒表達或是忍耐上的拿捏；後者則是聚焦於滿足己方或是對方需求之間的拿捏，進一步提出中庸作為拿捏行為與心理適應之間的調節變項。研究一與研究二皆符合預期，發現拿捏行為與心理適應的正相關在高中庸思維的情況下相對被強化，反之，在低中庸思維的情況下則沒有顯著相關。顯示以中庸思維為基底的拿捏行為，才能進退有據，綜觀全局權衡得失，彈性地因應不同情境而提升心理適應。

Na-Nie (拿捏) behavior refers to the ability to express theappropriate behavior in various situations. Although behavingappropriately is expected to correspond to positive psychologicaladjustment, it may also lead to anxiety and pressure. The current studyexamined a moderating factor that could contribute to these divergentresults. Zhong yong moderated the relationship between na-niebehavior and psychological adjustment. Both Study 1 and Study 2 supported our hypotheses: For those high in zhong yong thinking style,na-nie behavior promoted psychological adjustment, whereas for thoselow in zhong yong, there was no significant relationship between na-nieand psychological adjustment.
