Perceiving one's self as accepted by important others, such as parents, is fundamental and crucial for the well-being of each individual. One major aspect of interpersonal acceptance-rejection theory (IPARTheory) is examining how parental acceptance-rejection affects people's psychological adjustment. This theory has been validated in many countries and cultural groups around the world, but has not been utilized in the Vietnamese context. This research aims to assess the reliability of IPARTheory measures in Vietnam and applicability of the theory itself among a Vietnamese sample. Participants included 162 students from a high school in Hanoi (Mage = 15.58 years; 69.8% female). Materials consisted of Vietnamese versions of various IPARTheory measures: Parental Acceptance-Rejection Questionnaire, Personality Assessment Questionnaire, Interpersonal Relationship Anxiety Questionnaire, and a demographics form designed specifically for this research. Analyses show that psychological maladjustment significantly correlated with perceived paternal rejection, maternal rejection, and their subscales. Cronbach's alphas were strong, ranging from .73 to .97, except for the dependency subscale and hostility subscale of the Personality Assessment Questionnaire. Thus, the results provide evidence for the reliability of various IPARTheory measures in Vietnam. The relationships found in this study have implications for parents, teachers, and psychologists to employ in order to provide adolescents with appropriate guidance and intervention based on the importance of perceived parental acceptance-rejection.
