Item format and the structure of the Eysenck Personality Inventory: a replication.

A seven-choice response format for personality inventories allows finer distinctions by subjects than the traditional two-choice format. The Eysenck Personality Inventory was employed in the present study to test the hypothesis that use of the expanded format would result in a clearer indication of test structure. A principal components analysis with a varimax rotation retained two components for the two-choice format, clearly identifiable as Eysenck's "Neuroticism" and "Extraversion" which accounted for 16% of the variance. The expanded format retained four components accounting for 28% of the variance.

A systematic investigation of tardive dyskinesia in inpatients.

Although many scales to measure tardive dyskinesia have been developed, none has been widely accepted. The authors used the Abnormal Involuntary Movement Scale (AIMS) to evaluate a group of 293 inpatients who had been given a primary or secondary diagnosis of schizophrenia. They found a tardive dyskinesia prevalence of 30% using a criterion rating of 3 (moderate symptoms) or more on the AIMS. The prevalence figure declined as the criterion became more severe. They also found that women had a much higher prevalence of the disorder only when more severe symptoms were used as the criterion. They conclude that the AIMS is a reliable instrument for assessing tardive dyskinesia.

Tardive dyskinesia: age and sex differences in hospitalized schizophrenics.

An examination of the severity of tardive dyskinesia in psychiatric inpatients using the Abnormal Involuntary Movement Scale (AIMS) indicates differing trends with age for each sex. Females show a significant linear increase with age, while males display a significant curvilinear relationship. Reliable differences between males and females are found only for the 70-79 and greater than or equal to 80 year age groups. The differences between the sexes cannot be accounted for by differences in length of current hospitalization or by current level of neuroleptic medication. Possible reasons for the results are discussed.

Relationship between the Geriatric Interpersonal Evaluation Scale and the WAIS Verbal Scale.

27 psychogeriatric patients at Harlem Valley Psychiatric Center were tested by separate examiners on the WAIS Verbal Scale and the Geriatric Interpersonal Evaluation Scale to determine the relationship between these two tests. The sample was restricted to patients who were judged clinically to be "in contact," i.e., oriented as to time, place, and person. The correlation between the WAIS Verbal IQs and the geriatirc scale raw scores was .80; correlations with the individual verbal subscale scores ranged from .58 to .76. Relative advantages and disadvantages of the geriatric scale are discussed.

The effect of relocation on the satisfaction of psychiatric inpatients.

Fifty-one psychiatric inpatients were tested on a 36-item satisfaction scale before and after a reorganization at Harlem Valley Psychiatric Center. Patients were divided into three groups (Low, Medium, and High Stress) on the basis of whether they experienced no change as a result of the reorganization, environmental change only (different building), or environmental and social change (different building, different staff, different fellow patients). Patients in the three groups were matched on the basis of chronological age, length of hospitalization, and sex. Results indicated that there were no reliable differences among the satisfaction scores of the groups as a result of the relocation. This finding supports the hypothesis that the involuntary relocation of chronic psychiatric patients to another institutional treatment environment results in few demonstrable effects.
