Working under the assumption that the marital relationship has the greatest influence on the atmosphere of family life, 75 married couples performing parental tasks were examined and divided, using M. Braun-Gałkowska’s Marriage Success Scale, into two groups: married couples with a higher and lower level of satisfaction with their relationships. Next, the personality characteristics of the surveyed spouses were determined and compared using the following research tools: H.G. Gough’s and A.B. Heilbrun’s Adjective Check List, Z. Uchnast’s Sense of Security Questionnaire, the Emotional Intelligence Questionnaire developed by A. Ciechanowicz, A. Jaworowicz, A. Matczak, the Social Competence Questionnaire developed by A. Matczak, M. Kaźmierczak’s and M. Plopa’s Questionnaire of Marriage Communication, M. Braun-Gałkowska’s Family Attitudes Scale. Spouses with a higher level of satisfaction with their relationship, when compared to spouses with a lower level of satisfaction, are characterized by greater socialization, selfcontrol, and kindness; they obtained higher results determining their level of emotional intelligence and the effectiveness of their behaviours in intimate situations. The presented characteristics of spouses with a higher level of satisfaction with their relationship can be achieved as a result of personal development and, above all, of ongoing dialogue in the ever-changing reality of marital life. Taking advantage of the expanding offer of various forms of individual and group support can be useful in this respect. Workshops based on the participants’ involvement and referring to their own experiences are particularly helpful in working on personal development and deepening the marital relationship.
