The present study provides much needed empirical data on the adolescent loneliness experience. One hundred adolescents were given measures of loneliness, loneliness attributions, coping styles, and personal characteristics. Loneliness was positively related to state and trait anxiety, an external locus of control, depression, self-consciousness, and social anxiety and negatively related to self-reported attractiveness, likability, happiness, and life satisfaction. Lonely adolescents were also less willing to take social risks. Adolescents most often attributed loneliness to boredom and most often coped with loneliness by watching TV or listening to music. The implications of these findings for adolescent social development are discussed.

Regression analyses using Blood Pressure, Age, and the multiplicative effect of Blood Pressure and Age as predictors of performance (on selected tests from the Halstead-Reitan neuropsychological test battery) were done. Three hypotheses were tested with subjects ranging in age from 20 to 72 years of age: (1) blood pressure values predict neuropsychological test performance over a wide range of hypertensive and normotensive blood pressure values; (2) blood pressure predicts performance within the narrower range of normal and borderline values; (3) blood pressure X age interactions, when observed over this age and education range, are such that negative blood pressure effects on performance are larger for younger than older subjects. Regression analyses confirmed each of these hypotheses and indicated that strength of prediction was not reduced when participants free from hypertension-related complications and medication were tested. Blood pressure X age interactions were seen for Trailmaking-B Test and the Tactile Performance Test-Localization for the primary sample. However, only Blood Pressure main effects were observed for the Average Impairment Rating, the Categories Test, TPT-Memory and TPT-Localization when age, sex, and education were controlled. Implications of these findings for the role of blood pressure in aging research and for longitudinal studies with subjects free from the need for treatment with antihypertensive medications are discussed.

SUMMARY Fifty-four subjects with uncomplicated essential hypertension and 54 normotensive subjects were compared with regard to a widely employed clinical index of cognitive dysfunction (the Average Impairment Rating) calculated from neuropsychologkal tests that discriminate between brain-damaged and neurologically normal persons. Hypertensive subjects exhibited lower mean scores on this index when education was ignored, but results were not the same for highly educated and less well educated groups. There were no differences between exceptionally well educated hypertensive and normotensive subjects, but in the less well educated group, hypertensive subjects performed more poorly than normotensive subjects. The percentages of hypertensive and normotensive subjects scoring in a cognitively impaired range on the Average Impairment Rating were low and did not differ for either education group. These data 1) indicate the important role of subtle differences in education level with respect to positive or negative findings for studies comparing hypertensive and normotensive subjects and 2) illustrate the important role of clinical neuropsychological indices of cognitive dysfunction when one wishes to make meaningful inferences regarding cerebral cortical function in hypertensive subjects.

This study examined the effects of age and hypertension on WAIS performance. Previous studies have reported that hypertension adversely affects cognitive functioning, but few have considered the influence of hypertension on discrete age groups. Hypertension was found to be negatively associated with WAIS Verbal scores for younger (21 to 39 years) but not older (45 to 65 years) subjects. Further, younger subjects attained higher WAIS Performance scores than did older subjects. Medication history was not associated with performance levels for hypertensives, nor was performance of controls influenced by whether or not they were tested while on a diuretic. When WAIS Performance scores were analyzed for subjects matched on WAIS Verbal scores across age (21 to 39 vs 45 to 65 years) and blood pressure (normotensive vs hypertensive), a significant age by blood pressure interaction was found. The effect of blood pressure on Performance scores was found to be greater for younger than for older subjects. The association between plasma renin activity (PRA) level and WAIS Performance scores was also examined. Contrary to previous findings PRA was not related to Performance scores. The results are discussed in the context of previous hypertension research and their implications for comparisons across age levels.

The present study examined sex differences among college students in the quantitative and qualitative aspects of loneliness. Measurements of loneliness, emotional reactivity, and social risk taking were administered to 112 undergraduates. Males evidenced greater self-reported loneliness than females. Generally, affective and social risk-taking measures were more highly related to loneliness among males than females. The results suggest that loneliness is more likely to be associated with negative personal and affective self-evaluations for males than for females. Males may react to loneliness more negatively than females because of a tendency to attribute loneliness to personal failure rather than external, uncontrollable causes. Evidence also suggests that having difficulty in initiating social risks may contribute to loneliness for males more than females.
