Psychological aspects of sibling relational conflict vs. mental wellbeing levels in women’s perceptions

Abstract My research aim was to analyse sibling relational conflicts perceived by adult sisters and selected conflict determinants. The study also considered the discriminating significance of the sibling relational conflict intensity for experiencing mental wellbeing. The study included 240 adult women, coming from the Łódź district (M=41.94 SD=15.71). The following research instruments were applied: Adult Sibling Relationship Questionnaire (ASRQ) by C. Stocker et al. (1997) in its – adapted form by K. Walęcka-Matyja (2014), and Mental Health Continuum-Short Form by C.L.M. Keyes (2008) as adapted by D. Karaś et al. (2014). The research results allowed us to conclude about ambivalent kinds of bonds between siblings in adulthood, clearly indicating variation in the relational conflicts depending on the examined sisters’ ages. However, the study did not confirm the significance of gender constellation for experiencing general wellbeing by the examined women. It did verify the hypothesis that there is a significant role for age-level psychological well-being.
