RESUMEN
The purpose of the current study was to examine the serial mediating effects of rejection sensitivity and social withdrawal on parental psychological control and attitudes toward seeking professional psychological help among senior high school students. In November 2022, 648 students completed a self-report questionnaire. The parental psychological control scale, senior high school students' rejection sensitivity scale, social withdrawal scale, and attitudes toward seeking professional psychological help scale were used for measurement. Correlation analysis showed parental psychological control and rejection sensitivity were positively correlated with social withdrawal (r = 0.387, 0.466, 0.495, all p < 0.001). Parental psychological control and rejection sensitivity were significantly negatively correlated with social withdrawal and attitudes toward seeking professional psychological help (r = -0.325, -0.324, -0.397, all p < 0.001). Mediating effect analysis indicated that parental psychological control had a significant direct effect on attitude toward seeking professional psychological help, and rejection sensitivity and social withdrawal had significant serial mediating effects among parental psychological control and attitudes toward seeking professional psychological help in senior high school students. These aspects warrant attention as they play significant roles in influencing students' willingness to seek psychological assistance.
