“…From the EST perspective, the parent–child relationship was proposed to capture parent–child attachment security (Cummings & Davies, 2002), but measures of parent–child relationship vary (Erel & Burman, 1995). The IPC studies generally implement some form of emotional connection (or lack thereof) between a parent and a child, including different measures of parent–child attachment battery (e.g., Brock & Kochanska, 2016; de Silva et al, 2021; Grych et al, 2004), emotional quality of parent–child relationship (Gao & Cummings, 2019; Kouros et al, 2014), and parent–child conflict, particularly with older children (Bradford et al, 2008; El‐Sheikh & Elmore‐Staton, 2004; Sherrill et al, 2017; Skinner et al, 2021). Other specific aspects of parent–child relationship that have been investigated include communication quality (Mills et al, 2021), warmth (Skinner et al, 2021), and negative interactions, support, and behavioral control (Mastrotheodoros et al, 2019).…”
