Abstract

The validity of the Self-Consciousness Scale (SCS) for use with adolescents was investigated. Also, a path model of blood pressure based on the cognitive social learning theory was tested using sets of biological (i.e., family history of hypertension and age), psychological (i.e., public self-consciousness, private self-consciousness, suppressed anger and outwardly expressed anger), and lifestyle (i.e., relative weight and smoking) variables.Subjects were 169 female and 124 male adolescents from the southeastern United States. Parents provided information about the subjects' family history of hypertension and health. Subjects completed the SCS and Anger Expression Scale and a health questionnaire. Subjects' blood pressures, weights, and heights were assessed. Data from all subjects were used for the SCS analyses. Data from 36 subjects who reportedly had health problems or used drugs with cardiovascular effects were excluded from the path model analyses.The SCS data were factor analyzed. Based on the initial analysis, four items were excluded from the data. The subsequent factor analysis suggested that the SCS is a valid measure of the dimensions of self-consciousness in adolescents. Test-retest reliabilities and internal consistencies of the SCS showed reasonable reliability. Comparisons of the SCS scores between college students and adolescents and between female and male adolescents were made.The path model was tested separately for males and females on both systolic blood pressure (SBP) and diastolic blood pressure (DBP), using hierarchical multiple regression analyses of sets. Although the variables collectively explained a significant amount of variance in DBP and SBP for both sexes, few had significant direct and total effects on DBP and SBP, and none had indirect effects on DBP or SBP. Sex differences emerged in the variables' effects on DBP and SBP and the variables' effects on other variables. DBP and SBP increased as relative weight increased for both sexes. No other variables influenced SBP or DBP for males or SBP for females. Females with a positive family history of hypertension had higher DBPs. Females' DBPs decreased as private self-consciousness increased. The implications of the findings and suggestions for future research are discussed.
