The impact of psychological attributes on changes in disability among low-functioning older persons.

We studied the impact of four psychological attributes (neuroticism, extraversion, mastery or perceived control, and general self-efficacy expectancies) on changes in disability in a community-based sample of 575 low-functioning elderly persons between 1993 and 1995. Unlike elderly persons with low or medium levels of mastery and general self-efficacy expectancies, older persons with high levels of such attributes showed no significant increase of disability between 1993 and 1995. However, multivariate analyses showed only unique contributions of mastery to changes in disability. Neuroticism and extraversion were found to be not related to changes in disability, supporting previous research outcomes. Findings highlight that, particularly, feelings of perceived control are crucial for maintaining functional ability in later life.

Marital discord and well-being in older adults: is the association confounded by personality?

The associations between marital discord and multiple measures of well-being (depression, anxiety, life satisfaction, and self-esteem) were evaluated in a population-based sample of 416 couples in which the husband was 65 years or older. Results indicated that greater marital discord was associated with greater depression and lower life satisfaction and self-esteem. Furthermore, the associations between marital discord and well-being remained significant when statistically controlling for the rival explanation of the Big Five personality traits. Finally, there was little evidence for gender differences in the magnitude of the associations between marital discord and well-being. Findings suggest that marital discord is an important correlate of multiple measures of well-being in older individuals and that this association is not confounded by the Big Five personality traits.

Personality and psychopathology in schizophrenia: the association between personality traits and symptoms.

Research has indicated that stable individual differences in personality exist among persons with schizophrenia, and that they likely predate the onset of illness. Little is known, however, about whether individual differences in personality are related to levels of psychopathology. This study tested the hypotheses that levels of Extroversion, Neuroticism, and Psychoticism are associated with symptomatology. Accordingly, measures of these dimensions of personality and of symptomatology were obtained simultaneously for 113 male subjects with schizophrenia or schizoaffective disorder. Next, subjects were characterized as having high or low levels on each personality dimension and their scores on the five components of the Positive Negative Syndrome Scale were compared using multivariate and univariate procedures. Results indicate that extroverted subjects had lower levels of Positive, Negative, and Emotional Discomfort symptoms, and higher levels of Excitement symptoms than introverted subjects. Subjects with higher levels of Neuroticism had higher levels of Positive and Emotional Discomfort symptoms than subjects with lower levels of Neuroticism. No differences in symptoms were found among subjects with higher versus lower levels of Psychoticism. Results suggest individual differences in personality are associated with psychopathology in schizophrenia and may help further explain the heterogeneity widely observed in this disorder.

A relationship between Eysenck's P scale and change in muscle action potentials with attention to perceptual tasks.

An experiment is described in which an index of change in muscle tension produced by perceptual discrimination tasks, and scores on Eysenck's PEN scales, were measured on 39 university students. It was hypothesized that if P is an index of psychoticism, as has been claimed (Eysenck & Eysenck, 1968) then an index of one central feature of so called 'psychotics', namely attention difficulty while decision making, should correlate positively with P. P was found to correlate significantly with a measure of increase of EMG on the perceptual discrimination tasks (r = 0-54, P less than 0-001). Correlations of this index with N and E were zero. The results are considered to be particularly significant, since scores on P, E and N gave almost zero intercorrelations in the sample tested, and L scores were exceedingly low. Further evidence is provided which suggests that both P and muscle tension increase are directly related to the degree of endorsement of paranoid ideas.

Am empirical classification of psychopathic personality.

Personality profiles of 79 non-psychotic male offenders admitted to a security hospital were subjected to a cluster analysis. Four profile types were generated, classifying four-fifths of the sample, and differences were found between the types in previous antisocial behaviour. Two of the types were identifiable as primary and secondary psychopaths, while the remaining two showed little resemblance to the concept of the psychopathic personality. The primary psychopaths were extraverted but not neurotic, while the secondary psychopaths were neurotic, but not extraverted. Both were highly impulsive but distinguished by a dimension of sociability-withdrawal.
