This study examined associations between self-reported family wealth and parent–child relationships, by contrasting three theoretical perspectives on the shape of the association. The study utilized data from the Norwegian part of the “Health behaviour in school-aged children study (HBSC) 2013/2014”, with a sample of 3383 children aged 11–15 years old. The shape of associations between family wealth and parent–child communication were tested using regression spline models with knots at 1 SD below mean family wealth and at 1 SD above mean family wealth. The regression spline models showed that increasing family wealth was associated with easier family communication, clearer family communication, and higher family support. Results revealed that for boys, the association between family wealth and outcomes was stronger for the lower segment of family wealth, than in medium and high segments of family wealth. For girls, the gradient across level of wealth was monotone, with higher parent–child communication and higher family support at higher family wealth. To conclude, the results from this study suggest a nonlinear pattern of inequality in parent–child relationships across the range of family wealth.
