Young adults are characterized by the fact that they are no longer in the period of adolescence, but still in a transition phase towards adulthood. They are therefore undergoing major changes, particularly in their relationships with their parents and with romantic partners. The link between attachment and the quality of interpersonal relationships has been widely documented, and a positive association between attachment security and good relationship quality has been widely shown in the literature (Berlin, Cassidy, & Appleyard, 2008). The study of the effects of mindfulness on the quality of interpersonal relationships has grown rapidly over the last fifteen years. The results point to a positive association between high levels of mindfulness and satisfactory relationship quality (McGill et al., 2016). Moreover, it seems that mindfulness and attachment are also linked. The current study aimed at better understanding the unique and combined roles of mindfulness and attachment in predicting relationship quality with parents and with romantic partners.
1.2. Attachment and the quality of interpersonal relationships
Attachment is constructed from birth and corresponds to the affective bond that develops between the infant and the parent or any other person taking care of the child during the first years of life (Bowlby, 1977). Some authors hypothesized that early attachment, attachment to parents, continue to influence relationships in adulthood, particularly via the working models of self and others that the individual has internalized (Mikulincer & Shaver, 2007). In adult attachment, four prototypical attachment models have been defined to interpret positive or negative images of self and others (i.e., internal working models): secure attachment, anxious-preoccupied attachment, anxious-avoidant attachment and fearful-avoidant attachment (Bartholomew & Horowitz, 1991). Adult attachment can also be understood along two dimensions: anxiety, which refers to the fear of abandonment, and avoidant attachment, which refers to the fear of intimacy and dependence (Fraley, Waller, & Brennan, 2000; Mikulincer & Shaver, 2007).
Dinero et al. (2008) showed that parental attachment had an indirect contribution through both romantic interaction and attachment security on young adult. Similarly, Nosko et al. (2011) found that positive parent-child relationship could have an impact on the quality and development of romantic relationship. However, no study has confirmed these findings and the direction of these associations. Some studies have shown that an individual's attachment style with their romantic partner, or in their romantic relationship, is not correlated with parental attachment (Furman, Simon, Shaffer, & Bouchey, 2002; Fraley & Shaver, 2000), and the nature of the attachment may vary depending on the relationships involved (Caron, Lafontaine, Bureau, Levesque, & Johnson, 2012; Ross & Spinner, 2001). It is therefore useful to study other related variables that could help understand what may influence de role of attachment styles on relationship quality. One of the variables that may influence this relationship is trait mindfulness.
1.3. Mindfulness and the quality of interpersonal relationships
Mindfulness can be defined as the awareness that arises from deliberate, non-judgmental attention to the present moment (Kabat-Zinn, 2003). It can be represented as a dispositional trait (Jones, Welton, Oliver, & Thoburn, 2011) on a continuum ranging from low daily frequency of mindfulness to high frequency (Brown & Ryan, 2003). Over twenty years ago, authors suggested that mindfulness should promote a greater sense of connection (Kabat-Zinn, 1993; Welwood, 1996). More recent studies on the association between mindfulness and quality of interpersonal relationships, particularly romantic relationships, have underlined a positive correlation (Barnes, Brown, Krusemark, Campbell, & Rogge, 2007; Brown & Ryan, 2007; Burpee & Langer, 2005; Jones et al., 2011, Pepping, Davis, & O’Donovan, 2013; Wachs & Cordova, 2007). This relationship appears to be explained by the fact that mindfulness is also positively correlated with emotional intelligence and social skills (Baer, Smith, & Allen, 2004; Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006; Walchs & Cordova, 2007), as well as empathy (Dekeyser, Raes, Leijssen, Leysen, & Dewulf, 2008). Indeed, Fonagy et al. (2002) have also shown that mindfulness is close to the concepts of reflexivity and mentalization, i.e. the ability to understand the relationships of others in relation to their underlying mental states, thoughts, beliefs or intentions, which are necessary for good relationship quality. However, although it appears that a high level of mindfulness promotes better romantic relationships, and that this ability can be trained and improved (Kappen, Karremans, & Burk, 2019), some authors question the accessibility of these interventions for all individuals based on other individual characteristics (Farias & Wikholm, 2016). It is therefore useful to better understand how mindfulness may influence attachment, and hence relationship quality.
1.4. Mindfulness and attachment
The working models of self and others, developed from childhood, contain 'guidelines' and 'prototypes' for future relationships, including friendships and romantic relationships. Authors have shown that attachment styles in adulthood are however changeable (Davila, Karney, & Bradbury, 1999; Nosko et al., 2011). It is therefore necessary to study variables that may influence how attachment styles guide future relationship models or help remain more open to new attachment styles during adulthood. Many studies have shown a positive link between secure attachment and mindfulness (Pepping, O’Donovan, & Davis, 2014; Shaver, Lavy, Saron, & Mikulincer, 2007; Walsh et al., 2009). In romantic relationships, Jones et al. (2011) found that anxious and avoidant attachments mediated the relation between trait mindfulness and marital satisfaction. However, Pepping et al. (2015) showed that there was no direct, immediate and causal relationship between attachment and state mindfulness. Specifically, improving one did not lead to an improvement in the other, in either direction. The relationship between mindfulness and attachment is therefore complex, and needs further studies to analyse their respective roles and mutual influences.
1.5. The present study
The literature shows that attachment and mindfulness are correlated with relationship quality. This study therefore aims to refine the understanding of the link between these three variables according to the type of relationship considered (romantic vs. family). Moreover, the transition period between adolescence and adulthood corresponds to a period during which attachment style is stronger associated to development of close relationships (Feeney, 2004). For this reason, the study focuses on young adults, first-year university students. This population is also interesting for this study because they are likely to be non-experts in mindfulness. Furthermore, young adults tend to seek emotional support from friends and romantic partners rather than parents during the transition to adulthood (Sukhawathanakul, Ames, & Leadbeater, 2020). This would imply that the relationships young adults have with their friends and romantic partners are flourishing, and those with their parents are becoming less predominant. The current study therefore aimed at studying the role of adult attachment in the quality of romantic relationships and the role of attachment to parents in the quality of family relationships, and seeks to identify a possible mediator of these relationships: mindfulness, which could act as a resource fostered by secure attachment which could promote relationship quality.
The following two hypotheses were therefore put forward:
Hypothesis 1
Mindfulness mediates the relationship between adult attachment and the quality of romantic relationship.
Hypothesis 2
Mindfulness mediates the relationship between parental attachment and the quality of family relationship.
