In the following study, 187 fathers of young children contributed by completing questionnaires assessing paternal stress, paternal sense of competence, father’s involvement and socioeconomic situation. If disadvantaged fathers feel less competent and more stressed in their paternal role, they are as much involved as wealthier fathers. Furthermore, financial constraint perception seems to play a central role in the explanation of how fathers experience their paternity. Following these results, some suggestions regarding interventions towards these fathers will be offered.
