# Music@Home–Retrospective: A new measure to retrospectively assess childhood home musical environments

## TL;DR

This paper introduces a new tool to assess childhood home musical environments based on adult recollections, linking it to later musical and emotional outcomes.

## Contribution

The novel contribution is the development and validation of the Music@Home–Retrospective scale for retrospective assessment of early musical environments.

## Key findings

- A 20-item scale with five subscales was validated through exploratory and confirmatory factor analyses.
- The scale correlates with adult musicality, melodic perception, and well-being.
- Two new dimensions of childhood musical environments were identified: attitudes and social listening contexts.

## Abstract

Early home musical environments can significantly impact sensory, cognitive, and socioemotional development. While longitudinal studies may be resource-intensive, retrospective reports are a relatively quick and inexpensive way to examine associations between early home musical environments and adult outcomes. We present the Music@Home–Retrospective scale, derived partly from the Music@Home–Preschool scale (Politimou et al., 2018), to retrospectively assess the childhood home musical environment. In two studies (total n = 578), we conducted an exploratory factor analysis (Study 1) and confirmatory factor analysis (Study 2) on items, including many adapted from the Music@Home–Preschool scale. This revealed a 20-item solution with five subscales. Items retained for three subscales (Caregiver Beliefs, Caregiver Initiation of Singing, Child Engagement with Music) load identically to three in the Music@Home-–Preschool Scale. We also identified two additional dimensions of the childhood home musical environment. The Attitude Toward Childhood Home Musical Environment subscale captures participants’ current adult attitudes toward their childhood home musical environment, and the Social Listening Contexts subscale indexes the degree to which participants listened to music at home with others (i.e., friends, siblings, and caregivers). Music@Home–Retrospective scores were related to adult self-reports of musicality, performance on a melodic perception task, and self-reports of well-being, demonstrating utility in measuring the early home music environment as captured through this scale. The Music@Home–Retrospective scale is freely available to enable future investigations exploring how the early home musical environment relates to adult cognition, affect, and behavior.
