The COVID-19 pandemic and the confinement experience have significantly
affected the relationship between young adults and their parents. The present study
focuses on the design and validation of the Perceived Young Adult Lockdown Parental
Relationship Scale (PYALPRS), a measure assessing two dimensions of the child–parent
relationship associated with the COVID-19 lockdown period: Oppression-Conflict and
Closeness-Support. After a phase of construct definition and item design and purification,
100 Italian young adults (M = 24; SD = 3.9) were recruited to explore the factor structure of
the scale. Then, a sample of 259 Italian young adults (aged 18–35; M = 24; SD = 3.8) was used
to demonstrate the psychometric validity of the scale. The results of our confirmatory factor
analysis, which resulted in high goodness of fit scores, support two identifiable factors
reflecting the theory-based constructs of the PYALPRS. Moreover, internal consistency and
convergent and divergent validity analyses show that the PYALPRS can be considered a
reliable and valid instrument. ANOVA demonstrated that there were significant differences
between being a cohabitant or single as well as between different perceptions of the home
space during lockdown on the Oppression-Conflict dimension, while a larger home space
perception was associated with the Closeness-Support dimensio
