“…Previous research has provided support for the HAPA constructs in predicting preventive health behaviours, with prominent roles for outcome expectancies, self‐efficacy, planning, and action control (Schwarzer & Hamilton, 2020; Zhang et al., 2019). Recent meta‐analytic evidence provides support for some of the proposed relationships among HAPA motivational factors, identifying social cognition constructs self‐efficacy, attitude, and intention as significant correlates of parental supervised toothbrushing (Smith et al., 2020). While a limited evidence base has prevented a meta‐analysis of self‐regulatory factors in relation to parental supervised toothbrushing (Smith et al., 2020), HAPA volitional processes (i.e., self‐regulatory skills) have been shown to relate directly to oral hygiene behaviours in populations other than parents of preschoolers (Gholami, Knoll, & Schwarzer, 2015; Hamilton, Bonham, Bonham, Bishara, Kroon, & Schwarzer, 2017; Lhakhang et al., 2016; Zhou et al., 2014).…”
