Ecological momentary assessment of parent-child attachment via technological devices: A systematic methodological review

Abstract

Despite extensive research about parent-child attachment using observational and self-report studies, complementary measures are needed to assess this construct objectively with ecological validity, as well as less obtrusiveness and reactivity than traditional measures. This systematic review describes existing technology-based ecologically momentary assessment (EMA) tools examining attachment-related emotions, cognition, and behaviors between the child and its parents. From the study’s inception until March 2021, four databases were searched resulting in 11,910 screened citations. Finally, 18 records were included, characterized by a broad variety of assessment tools, sample characteristics, study designs, and attachment outcomes. Technology-based EMA methods comprised audio, video, diary, and sensory assessment modalities, each occuying its methodological niche. When reported, the psychometric properties of the EMA methods were evaluated as very good; however, the included studies’ psychometric data was not completely examined. The main attachment outcomes assessed by EMA were emotional and cognitive reactions and actions of the children, the parents, and the dyad. Cognition was rarely assessed using EMA methods. Future research should focus on the complexity of attachment considering different ethnic backgrounds, multiple caregivers' viewpoints, gender aspects, as well as cognitive and dyadic contents in the naturalistic environment.
