Coping is the method through which people mobilize, adjust, manage, and harmonize various facets of themselves while under stress. Previous research has suggested that parents and children use similar coping strategies. Coping congruence refers to the similarity in coping strategies employed by two individuals within a relationship. The objectives of the present study were to analyze the congruence between caregivers’ and undergraduates’ coping behaviours and to evaluate how this congruence predicts relationship quality as measured by conflict in their relationship. 102 undergraduates (87 females, 15 males) and their caregivers (77 mothers, 7 fathers, and 2 listed as other) reported on their own coping behaviours and their perception of their relationship with the other. Pearson correlation coefficients measured congruence in coping behaviours and simple linear regressions predicted conflict based on congruence in coping. Undergraduates students did not consistently use the same coping strategies as their caregivers. Only use of Instrumental Social Support, Active Coping, Religious Coping, Behavioural Disengagement, and Restraint Coping were positively associated. The congruence in coping strategies did not consistently predict undergraduates’ or caregivers’ report on conflict in the relationship. However, low congruence on Behavioural Disengagement predicted caregivers’ report on conflict with the undergraduate. Problem- focused, emotion-focused, and dysfunctional coping scores did not predict conflict in the relationship. Possible explanations for these findings include limitations with congruence scores, that all types of coping may not be related to caregivers’ behaviour, that participants are young adults rather than children or adolescents, and that romantic relationships have become more important.
