This study aimed to understand the effects of family conflicts on the psycho-spiritual well-being of students in Catholic secondary schools in the Kabgayi Diocese,
Rwanda. It adopted a convergent parallel design mixed method. The study was guided by Murray Bowen’s family system theory. The target population of the study
were 2402 students and 29 teachers. The sample size was 347 participants, selected through simple random sampling. The objective of this study is to determine
the effects of family conflict on psycho-spiritual well-being of students studying in catholic secondary schools in Kabgayi Diocese. The data was collected through
a questionnaire, semi-structured interview. The results of the research objectives were analysed. For quantitative questionnaires, the researcher used frequencies,
tables and diagrams. Quantitative data was analysed descriptively using the Statistical Package for Social Sciences IBM (SPSS) version 23. The qualitative data
was analysed using the thematic analysis method. The findings of the study show that there is a significant negative relationship between family conflict and the
Psycho-spiritual well-being of students, where Pearson’s correlation coefficient of two variables r = -0.174, indicating that heightened conflict levels corresponded
with diminished psycho-spiritual well-being which shows that family conflicts have effects on student’s psycho-spiritual well-being. The study therefore
recommended the government to augment the access to school-based counseling services, wherein students can avail themselves of support and guidance from
adequately trained professionals. It is imperative that these services be easily accessible and provided without cost, thereby guaranteeing universal access
irrespective of students' financial circumstances.
