In recent years there has been a growing research interest in expanding knowledge about parental influence on youth mental health beyond adolescence, i.e. during emerging adulthood. At the same time, newer theoretical frameworks in developmental psychology suggest that some emerging adults may be more strongly affected by positive and negative parental behaviors than others, in terms of mental health outcomes. Research shows that environmental sensitivity, a trait that refers to the ease of perception and the depth of processing of information about the environment, may underlie such differences in sensitivity to environmental influences. This study aimed to examine the role of environmental sensitivity and perceived parental behavior (acceptance, rejection and control) in predicting psychological distress among emerging adults who live with their parents. In addition, we wanted to examine if predictive power of three perceived parental behavior variables for emerging adults' psychological distress depends on their level of environmental sensitivity. A total of 323 participants, aged between 19 and 30, filled out an online questionnaire that contained sociodemographic questions and measures of environmental sensitivity, perceived parental behavior (acceptance, rejection, control) and psychological distress. Results showed that environmental sensitivity and perceived parental control significantly positively, while parental acceptance significantly negatively predicted psychological distress among youth. A moderating role of environmental sensitivity in the relation between perceived parental control and psychological distress was found. A positive relation between perceived parental control and psychological distress was the strongest among highly sensitive youth, while among individuals with low environmental sensitivity this relation was not significant.
