Relation between social functioning and neurocognitive test results using the Optional Thinking Test in schizophrenia.

The current study investigated the relationship between clinical evaluations of social functioning and neurocognitive test results, including various fluency tests for assessing divergent thinking, in patients with schizophrenia. The Optional Thinking Test (OTT) was used to measure the ability of individuals to conceive of alternatives. This test assesses alternative thinking, or the capacity to generate solutions to problems. The current study examined 36 schizophrenia patients and 25 normal subjects using the Mini-Mental State Examination (MMSE), the Rey Auditory Verbal Learning Test (RAVLT), the Letter Cancellation Test (LCT), the Letter and Category Fluency Tests, and the OTT for neurocognitive assessment, as well as the Positive and Negative Syndrome Scale (PANSS), the Global Assessment of Functioning (GAF), the Social Functioning Scale (SFS), and the Life Assessment Scale for the Mentally Ill - Interpersonal Relations (LASMI-I) for clinical measures. The schizophrenia patients had significantly poorer performances on the MMSE, RAVLT, LCT (time), fluency tests, and OTT than the controls. In the OTT, the proportions of classified strategies were indistinguishable between the schizophrenia patients and the controls. Alternative thinking, as measured by the OTT, was correlated with verbal fluency and attention but was not correlated with the social functioning scores (GAF, SFS, LASMI-I), whereas the Means-Ends Problem-Solving was correlated with the GAF in schizophrenia. Patients with schizophrenia could conceive of the same categories of alternatives as healthy people, but could not conceive as many alternatives.

Social cognitive problem-solving in schizophrenia: associations with fluency and verbal memory.

This study assessed the relationship between social functioning and neurocognitive function in individuals with schizophrenia. Social cognitive problem-solving (SCPS) is a significant contributor to social competence and is an aspect of information processing that is involved in the identification and resolution of interpersonal or social problems. We examined 49 schizophrenia patients and 28 healthy controls using the means-ends problem-solving procedure (MEPS) for SCPS, the Rey Auditory Verbal Learning Test (RAVLT), the Wisconsin Card Sorting Test (WCST), and a series of fluency tests for neurocognitive assessment, as well as the Positive and Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning (GAF). Fluency tests can be used to evaluate divergent thinking, and a qualitative analysis was done of the fluency test responses. The results suggest that patients with schizophrenia have a significantly poorer MEPS performance than normal controls. In patients with normal RAVLT scores, MEPS scores were correlated with task-modified responses on the fluency test but not with any of the WCST scores. This suggests that SCPS is related to divergent thinking that requires concept flexibility and/or the conversion of viewpoint in patients with schizophrenia in whom verbal memory function is preserved.

Expressed emotion and social functioning in chronic schizophrenia.

The aim of this study was to reveal the relationships between family expressed emotion (EE), family evaluations of social functioning, and the psychopathologic symptoms of patients with schizophrenia. We examined whether EE influenced the social functioning of patients with schizophrenia. Forty-four subjects with schizophrenia and 82 of their relatives participated in this study. The Five-Minute Speech Sample (FMSS) was conducted to evaluate EE, and subjects were divided into high-EE and low-EE groups. The Positive and Negative Symptom Scale (PANSS) was used to assess symptom severity. Social functioning was compared between the two groups using the Social Functioning Scale (SFS). No differences in symptom severity or social adjustment, as evaluated by a global assessment of functioning, were observed between the two groups. However, the high-EE relatives tended to evaluate the social functioning of the schizophrenia patient in their family as being rather low and showed a strong dissatisfaction with the patient's social withdrawal and level of independence (competence). Furthermore, low-EE relatives in high-EE families showed the same tendencies. The family members who were evaluated as low-EE relatives in a high-EE family were dissatisfied with the patient's social withdrawal, level of independence (competence), and also their interpersonal functioning. In the chronic stable phase of schizophrenia, the attention of the family members may be more directed towards changes in social functioning; thus, the EE may reflect a family's attitude towards improvements in the patient's social functioning.

[Implementation of integrated mental health care in an urban district of Tokyo].

Japan had a long history of long-term hospital care and is now trying to change it into community-based psychiatry. Implementing comprehensive approach that has already been proven effective through evidence based data in one particular community, one has to overcome several local barriers, if the same approach is to be implemented in different situations, such as differences in socio-cultural background and health care system. This is a report of the activities of Minato Net 21 pointing out the "local barriers" on implementing comprehensive approach in an urban district of Tokyo.
