<p style="text-align: justify;"><strong>Objective. </strong>Adaptation of the Parental Stress Scale by J. Berry and V. Jones on a sample of mothers of Russian schoolchildren &ndash; first and fourth grade students of elementary schools in Nizhny Novgorod and the Nizhny Novgorod region. <br><strong>Background. </strong>Modern parenting research highlights the complex nature of parenting experiences, the diversity of parental practices, the changes associated with the child's upbringing and the dynamics of the family system, and the combination of both positive and negative emotions in parenting. However, there is a noticeable shortage of tools in the Russian-language literature to measure both parental satisfaction and parental stress. <br><strong>Study design. </strong>The study was conducted using an online survey within the &ldquo;Longitudinal study of factors of school failure&rdquo;, implemented in Nizhny Novgorod and the Nizhny Novgorod region. <strong>Participants. </strong>The study included a sample of 900 mothers of fourth grade and 1120 mothers of the first grade school students. <strong>Measurements.</strong> Exploratory and confirmatory factor analysis and McDonald's Omega coefficients were used for psychometric data analysis. The PERMA Profiler questionnaire and correlation analysis were used to assess validity based on convergent and discriminant evidence. The data was analyzed in the Jamovi 2022 and R programs. <br><strong>Results. </strong>Factor analyses of the internal structure suggest two factors, including 8 items each. The subscales &ldquo;Parental stress&rdquo; and &ldquo;Parental satisfaction&rdquo; demonstrate a high level of internal consistency. The assessment of validity based on the convergent and discriminant evidence confirms the reliability and validity of the instrument. <br><strong>Conclusions. </strong>The scale demonstrates good psychometric properties and can be used for parenting research, as well as in applied projects to improve parental competence and emotional support for parents.</p>
