Mattering is defined as experiences of feeling valued and adding value in different domains of life: self, relationships, work, and community. Mattering is a construct with great relevance across psychological and social issues. Research has suggested there may be value in understanding group differences in mattering. Following the recent validation of a scale which measures mattering across multiple domains of life (MIDLS), the present study analyzed a representative US sample to identify demographic group differences in domain-specific mattering. Despite the presence of few differences in Overall Mattering, significant differences were found among all domains and between groups for each demographic variable. Overall, high incomes, advanced degrees, and employment were most consistently associated with higher mattering across domains. In addition, individuals across demographic groups and domains were more likely to report adding value than feeling valued.Age, gender, ethnicity, and marital status correlations were found in certain domains. These results demonstrate the value of a multidimensional conception of mattering and provide initial insight into demographic differences in mattering in a United States, English-speaking sample.
