亲密关系的质量对个体的身心健康有着不可忽视的影响，而依恋模式会影响个体在亲密关系中的感受、认知和行为表现。然而，依恋模式也会在与亲密他人的互动中逐渐发生变化。Arriaga, Kumashiro, Simpson和Overall(2018)提出了依恋安全强化模型，指出可以从安抚不安全依恋和强化安全依恋两条途径，促使个体的依恋变得更加安全。以往研究更多地探索如何即时地安抚依恋焦虑和依恋回避，而忽视了如何帮助个体获得长程的安全依恋。现有的行为观察研究发现，伴侣的积极行为，例如欣赏、接纳、肯定、支持等，能够促使个体的依恋在较长的时间内变得更加安全，但没有对行为进行具体的区分。因此，本研究拟考察亲密关系中，伴侣的欣赏这一具体方面对个体的依恋模式和关系质量的影响。 在研究一中，处于亲密关系中的480名被试填写了翻译后的关系中的欣赏量表、亲密关系体验量表、亲密关系质量量表，以修订关系中的欣赏量表中文版。结果发现，中文版关系中的欣赏量表具有良好的内部一致性、结构效度和效标关联效度。但反向题载荷较低，未来研究可以进一步探索其原因。 在研究二中，通过对137对亲密伴侣的问卷调查，考察伴侣双方的欣赏伴侣和被伴侣欣赏程度对双方的依恋模式和关系质量的影响。结果发现：（1）在亲密关系中，女方的感受更差；双方都会低估伴侣对自己的欣赏程度。（2）个体欣赏伴侣的程度正向预测自身的关系质量，负向预测自身的依恋回避，但不能显著预测自身的依恋焦虑；依恋回避和依恋焦虑均负向预测关系质量。（3）个体欣赏伴侣的程度也会影响伴侣的依恋模式和关系质量：个体对伴侣的欣赏可以负向预测伴侣的依恋焦虑，个体越欣赏伴侣，伴侣的依恋焦虑程度越低；个体的依恋回避可以负向预测伴侣的关系质量，个体越依恋回避，伴侣的关系质量越差。（4）依恋模式部分中介欣赏对关系质量的影响：个体的依恋回避在欣赏伴侣对自身关系质量和对伴侣关系质量的预测中都起到中介作用；男方对女方的欣赏，还可以通过降低女方的依恋焦虑，提高女方的关系质量，反之，这一效应却不存在。（5）男方自我报告的被伴侣欣赏程度，可以通过降低男方的依恋焦虑和依恋回避，提高男方的关系质量。这一路径与上一条结论中，女方报告的对男方的欣赏，无法通过降低男方依恋焦虑，提高男方的关系质量的结论存在差异。 在研究三中， 通过预实验确定“表达欣赏”操纵的具体要求。正式实验中，40对情侣在前中后测均填写中文版关系中的欣赏量表、亲密关系体验量表、亲密关系质量量表。对照组的30对情侣同样填写3次问卷。在实验前后，双方都填写积极消极情感量表。结果发现：（1）表达欣赏可以有效提高个体感受到的被欣赏程度，并带来良好的情绪感受。（2）感受到伴侣的欣赏后，女方的依恋焦虑显著下降，这一效应在一周后仍然存在。但男方的依恋焦虑没有明显变化。依恋回避均没有变化。（2）表达欣赏对亲密关系质量没有明显影响，这可能存在多方面原因，未来可以继续探索如何提升关系质量。

The quality of romantic relationship has great impact on individual’s physical and psychological health. Adult attachment has been studied as an important predictor of cognitive, emotional, and behavioral indicators of romantic relationship quality. However, attachment changes during the interactions with close others. Arriaga, Kumashiro, Simpson and Overall(2018) proposed the Attachment Security Enhancing Model based on previous theories and studies. They posited that there are two pathways to help people gain greater security, which are buffering insecurity and enhancing security. Most studies were working on mitigating in-the-moment attachment anxiety and avoidance, whereas few studies worked on enhancing long-term security through promoting internal working models of self and others. Some previous behavior observation studies showed that partner’s positive behaviors, such as appreciation, acceptance, affirmation and support, could enhance long-term attachment security. But they often merge the positive behaviors rather than concentrating on one specific aspect. The study aimed at clarifying the impact of appreciation in romantic relationship on adult attachment and relationship quality. In study 1, 480 participants who were involved in romantic relationship completed translated Appreciation in Relationship Scale(AIR), Experience of Close Relationships Scale (ECR), the Quality of Relationship Index(QRI) online. Results showed that the AIR-Chinese Version had adequate internal consistency, structure validity and criterion-related validity. Future research could pay more attention to reversed coded items since their loadings were relatively lower. In study 2, 137 romantic couples completed AIR, ECR, QRI online and we examined the actor and partner effect of appreciation in relationships on adult attachment and relationship quality. The results were listed below: (1)Women rated lower than man on the appreciative subscale, appreciated subscale and relationship quality; Both men and women rated lower on appreciated subscale compared with the rating of appreciation given by their partner. (2)Actor effect: the appreciative scores directly positively predicted their relationship quality, negatively predicted attachment avoidance, but the appreciative scores could not predict attachment anxiety; both attachment avoidance and anxiety negatively predicted relationship quality. (3)Partner effect: both for men and women, the actor’s appreciation negatively predicted the partner’s attachment anxiety, the actor’s attachment avoidance negatively predicted the partner’s relationship quality. (4)Mediating effect: adult attachment partially mediated the impact of appreciation on relationship quality. the actor’s appreciation negatively predicted the actor’s avoidance, then improved the partner’s relationship quality. Only men’s appreciation to women could reduce the women’s attachment anxiety, thus enhancing the women’s relationship quality. But the reverse pathway was not significant. (5) Different from the appreciative scores reported by women, the appreciated scores reported by men could enhancing men’s relationship quality through men’s attachment anxiety and attachment avoidance. In study 3, the details of “express appreciation” manipulation was clarified. 40 romantic couples completed AIR, ECR, QRI on pre-test, mid-test, post-test. So do 30 romantic couples as control group. The experiment group also completed PANAS before and after the experiment. Results showed that: (1) After the manipulation, participants reported higher positive affect and appreciated scores, which supported the manipulation could promote appreciated feelings and positive affect. (2) After being appreciated by partners, women reported lower attachment anxiety both in mid-test and post-test, while men showed no significant changes in attachment anxiety. There are no significant changes for attachment avoidance. (3) Relationship quality showed no significant changes after manipulation, which might result from various reasons. Future studies could explore how to promote relationship quality.
