The development, validation, and applications of a computerized measurement of cognitive impairment from the content analysis of verbal behavior

Expressive language disturbance in borderline personality disorder in response to emotional autobiographical stimuli

Clinicians recognize expressive language disturbances in borderline personality disorder (BPD) as a feature attenuating psychiatric history-taking. Neuroimaging studies demonstrate activation of key differentiating neural networks characterizing a traumatic memory system in BPD patients. Yet there are few BPD studies evaluating expressive language disturbances in response to emotionally salient, clinically relevant stimuli and no controlled studies. The aim was to examine expressive language disturbances in response to a clinically relevant emotional stimulus, the Adult Attachment Interview (AAI). Twenty BPD participants and 20 age-, sex-, and education-matched controls were administered the AAI. Verbatim transcripts were analyzed by four computerized measures designed to evaluate various linguistic components of speech (i.e., overall expressive language impairment, lexical complexity, syntactic complexity, and semantic complexity). BPD participants evidenced significantly greater levels of overall expressive language impairment and reduced syntactic and lexical complexity, but not semantic complexity scores. Detailed linguistic profiles demonstrated specific deficits linked to BPD.

Mutilation anxiety differs among females with fibromyalgia and functional dyspepsia and population controls

BACKGROUND

Studies using self-report rating scales suggest a considerable overlap regarding symptom complaints in patients with fibromyalgia (FM) and functional dyspepsia (FD), while clinical assessments point to important psychological differences.

PURPOSE

To test the hypothesis that measurement of psychological state by means of content analysis of speech will demonstrate differentiation between the two patient groups and between patients with these disorders and age-matched population-based random sample controls.

METHOD

The Giessener Symptom Complaints Checklist assessed somatic complaints. The computerised Gottschalk-Gleser content analysis method assessed psychological state in 42 females with FM, 17 females with FD and 48 population-based, randomly selected control subjects.

RESULTS

FM patients score higher on mutilation anxiety than FD and control subjects. FD patients had the highest score for death anxiety. Mutilation anxiety and low hope score identified FM patients (sensitivity 68%, specificity 81%, overall classification 75%), but only 19% of the variation in total somatic complaints could be predicted from these or other psychological state scores. In FD patients, however, death anxiety explained 59% of the variance in gastrointestinal complaints.

INTERPRETATION

Psychological state was differentiated among the three groups. Mutilation anxiety may be a psychological marker of an underlying neurobiological vulnerability for FM or may represent a secondary long-term consequence of chronic illness. In FD, death anxiety is directly related to symptom complaints, suggesting a stronger etiological association between emotions and somatic complaints in this disorder.

Computer detection of cognitive impairment and associated neuropsychiatric dimensions from the content analysis of verbal samples

This is a report of a study testing the capacity of a computerized measure of the content analysis of five minute verbal samples to detect and measure cognitive impairment and comorbid neuropsychiatric dimensions in 117 drug-abusing inpatients. The cognitive impairment scores obtained from the computerized procedure correlated significantly with independent scores from the Trails B and Stroop Color and Word test as well as with ANAM (Automated Neuropsychiatric Assessment Metric) neuropsychological tests, including the Matching to Sample Efficiency and Accuracy, the Code Substitution Efficiency, the Continuous Performance Task Efficiency and Accuracy, the Code Substitution Delayed Recall Accuracy, and the Simple Reaction Time Efficiency. When the computerized verbal-content-analysis-derived cognitive impairment scores were combined with scores of selected other ANAM measures, more and higher intercorrelations occurred with Trails A, Trails B, the Stroop Color and Word test, and the Wisconsin Card Sort test. In addition, validated measures of a broad range of associated neuropsychiatric dimensions can be obtained simultaneously from the same five minute verbal samples providing the cognitive impairment scores. No significant effects were found on the cognitive impairment scores of age, education, gender, race, and duration of drug-abuse abstinence.

Psychotherapy with multiple-sclerosis patients

We wanted to find out if psychotherapy may influence the course of the physical aspects of multiple sclerosis and the consequences of psychotherapy for coping processes. 46 patients diagnosed with multiple sclerosis who had chosen to undergo a 1-yr. group psychotherapy treatment were compared with a control group of 24 multiple-sclerosis patients without such treatment. They were given the Giessen test (personality test), the Achievement Capacities Questionnaire by Kesselring, an intensive interview as well as the content analysis scales of verbal behavior by Gottschalk and Gleser. The various tests were carried out at each of four times of measurement with a 2-yr. follow-up. There were significant changes in the area of relationships and aggressive loosening (interview) between the Therapy and Control groups. Several changes were also found with regard to physical symptoms (Achievement Capacities Questionnaire) in the Therapy group compared to the Control group, e.g., increases in physical mobility and decreases in care of the body. The decreases appear to be a known effect of therapy with psychosomatic disorders. We interpret it psychoanalytically as resistance against releasing anxiety of counter-cathected motives which multiple sclerosis helps to keep unconscious. In a follow-up, the Therapy group showed greater optimism and physical improvements, e.g., decrease in feeling cold and lack of energy. Some positive changes appeared in both groups, such as, for example, an improvement of cognitive impairment (Gottschalk & Gleser). It appears that the attention from the research itself may have affected both groups because some members of both groups were in contact and hence the Control group was also informed about the research project and its underlying hypothesis.

Stuttering: neuropsychiatric features measured by content analysis of speech and the effect of risperidone on stuttering severity

Positron-emission tomographic (PET) studies and genetic research of stuttering have recently revealed underlying cerebral neurobiologic contributing factors in this disorder. We aimed to assess whether cognitive impairment and other neuropsychiatric dimensions could be detected through computerized content analysis of short samples of speech from stutterers, and whether administration of risperidone in a double-blind placebo-controlled study could decrease the severity of stuttering, as well as any of the neuropsychiatric features of these stutterers. A group of 21 stutterers with the developmental form of stuttering, an onset before age of 6 years, aged 20 to 74 years, and who were otherwise free of major medical or psychiatric problems, initially gave a 5-minute tape-recorded speech sample in response to purposely ambiguous instructions to talk about any interesting or dramatic life experiences. Then, half of these subjects (n = 10) were randomly selected to receive 6 weeks of risperidone treatment up to 2.0 mg/d and the other half (n = 11) were administered a placebo. Both groups of subjects gave a second verbal sample after 6 weeks of treatment. Significantly elevated cognitive impairment and social alienation-personal disorganization scores, derived from the computerized content of the initial 5-minute speech samples, were found. After 6 weeks, the risperidone group improved significantly on a measure of severity of stuttering but did not improve on the percentage of time spent stuttering. The placebo group did not improve on either measure of stuttering. The psychopathological processes of subjects who received risperidone treatment, including those with elevated cognitive impairment and social alienation-personal disorganization, did not change significantly. However, stutterers who had lower scores on verbal content analysis-derived shame anxiety, guilt anxiety, or hostility inward measures improved significantly more with risperidone than stutterers with higher scores on these measures. The findings of elevated cognitive impairment and social alienation-personal disorganization scores of adult stutterers with the early developmental form of stuttering are consistent with the neurobiologic abnormalities found in PET-scan and genetic research involving stutterers. Risperidone (< or =2.0 mg/d) can reduce the severity of stuttering while not significantly affecting the magnitude of neuropsychiatric dimensions such as cognitive impairment or social alienation-personal disorganization. The less the inward shame, guilt, or hostility of the stutterers, the better the beneficial effect of risperidone on the severity of stuttering.
