A deterioration in information-processing performance is commonly recognized in patients with chronic schizophrenia. Although the enhancement of cognitive skills in patients with schizophrenia is important, the types of external stimuli that influence performance have not received much attention. The aim of present study was to clarify the effects of spatial and affordance compatibility in patients with schizophrenia, compared with those in healthy people. The subjects (25 patients with schizophrenia and 25 healthy controls) participated in two experiment examining the effects of the spatial location of stimuli and the action-relevance of objects. The results showed that the effect of spatial compatibility was similar in both the patients and the controls, whereas the influence of action-relevant objects was not highlighted in either patients with chronic schizophrenia or healthy controls. These findings provide important evidence of a normal spatial compatibility effect in patients with chronic schizophrenia. However, further research examining the affordance compatibility effect is needed, taking into consideration the symptomatology and the severity of the social functioning level in patients with schizophrenia.

BACKGROUND: The circadian rhythm in older adults is commonly known to change with a decrease in physical activity. However, the association between circadian rhythm metrics and physical activity remains unclear. The objective of this study was to examine circadian activity patterns in older people with and without dementia and to determine the amount of physical activity conducive to a good circadian measurement. METHOD: Circadian parameters were collected from 117 older community-dwelling people (66 subjects without dementia and 52 subjects with dementia); the parameters were measured continuously using actigraphy for 7 days. A receiver operating characteristic (ROC) curve was applied to determine reference values for the circadian rhythm parameters, consisting of interdaily stability (IS), intradaily variability (IV), and relative amplitude (RA), in older subjects. RESULTS: The ROC curve revealed reference values of 0.55 for IS, 1.10 for IV, and 0.82 for RA. In addition, as a result of the ROC curve in the moderate-to-vigorous physical Activity (MVPA) conducive to the reference value of the Non-parametric Circadian Rhythm Analysis per day, the optimal reference values were 51 minutes for IV and 55 minutes for RA. However, the IS had no classification accuracy. CONCLUSIONS: Our results demonstrated the reference values derived from the circadian parameters of older Japanese population with or without dementia. Also, we determined the MVPA conducive to a good circadian rest-active pattern. This reference value for physical activity conducive to a good circadian rhythm might be useful for developing a new index for health promotion in the older community-dwelling population.

要旨：1年以上の入院生活および地域の中で生活している統合失調症患者22名（入院群11名，地域群11名）を対象に，腕時計型加速度計Actiwatch2（以下，AW2）による生活リズム評価と，統合失調症認知機能簡易評価尺度日本語版（以下，BACS-J）による認知機能評価を用いて，異なる環境下で生活する統合失調症患者の特性について比較・検討した．入院群は認知機能の著しい低下を示し，地域群は生活リズムの不安定さが認められた．主観的な評価に加え，AW2とBACS-Jは地域生活支援における精神科作業療法の効果の検証において有用な評価法になると考える．

ABSTRACT Background: Irregular circadian rhythm and cognitive impairment are frequently observed in patients with chronic schizophrenia. However, their effects in different living environments or with aging remain unclear. The aim of this study was to clarify the characteristics of circadian rhythm and cognition function in the patients with chronic schizophrenia. METHODS: This report described data collected using continuous wrist-active monitoring in real-life settings for seven days and the Brief Assessment of Cognition in Schizophrenia Japanese Version (BACS-J) from 10 inpatients with chronic schizophrenia, 10 outpatients with chronic schizophrenia, and 15 healthy elderly people. The Global Assessment of Functioning (GAF) Scale was used to measure the social functioning in the patients with chronic schizophrenia. RESULTS: The outpatients with chronic schizophrenia exhibited highly interrupted circadian patterns in terms of stability and the fragmentation of activity (p < 0.05) as indexed according to Interdaily Stability (IS) and Intradaily Variability (IV). The inpatients with chronic schizophrenia indicated the most stable rhythm (p < 0.05) and inactive state (p = 0.001) among the groups. Also, the inpatients with chronic schizophrenia showed poorer cognitive functioning with Z-scores of subtests except digit sequencing (p < 0.01). According to stepwise linear regression analysis, the motor speed of BACS-J and IS of circadian parameters were the most powerful variables to predict the GAF in patients with chronic schizophrenia. CONCLUSIONS: The characteristics of circadian rhythm and cognition function in the inpatients with chronic schizophrenia appear distinct from those in the outpatients and the healthy elderly people. Circadian rhythm and cognition function in the patients with chronic schizophrenia may, in part, be affected by different living environments.

アルコール依存症による認知機能の低下を示したクライアントに対し、人間作業モデル(Model of Human Occupation、以下、MOHO)の評価ツールである「作業に関する自己評価・改訂版(Occupational Self Assessment,Revised.以下、OSA-II)」を用いて、入院時から在宅による地域生活まで協業によるアプローチを実施した。OSA-IIによる協業により表出された意志と役割を踏まえたプログラムと生活環境の調整により、作業機能状態が改善し、在宅生活が実現した。地域支援にOSA-IIを用いた協業によるアプローチを継続することで、クライアントが生活を見直す機会となり、MOHOによるアプローチが入院生活から地域生活の支援に有用であることが示唆された。(著者抄録)
