Abstract
OBJECTIVE The clock drawing test (CDT) is being used regularly by medical professionals in a variety of settings to aid in assessing cognitive functioning in adults of all ages. As our technological environment has changed significantly, because of the inception of this measure, the use of and exposure to the analog clock have diminished. We investigated whether young adults, who have grown up in a mainly digital world, can draw and tell time on an analog clock. METHOD Participants aged 18-30 years (N = 80, Mage = 24.2, SD = 3.93), who self-identified as having normal cognition, completed the CDT, as well as setting hands on a pre-drawn clock and identifying analog clock times. RESULTS About 25% of participants received a CDT score below the expected range. There was a moderate, positive correlation between analog clock hand setting and time identification in the group who scored below the expected range on the CDT only (rs(16) = 0.472, p = .048). Most participants reported not wearing an analog watch. CONCLUSIONS Based on these findings, the CDT should be used with caution to screen cognitive functioning in young adults (i.e., aged 18-30 years). Consideration of an alternative approach to screening cognition and modifying cognitive assessments in which the CDT is embedded is recommended for this population. These findings warrant further investigation into CDT performance in the young adult population.

Abstract
Differences in emotion experience and emotion expression between patients with schizophrenia and the healthy population have long been the focus of research and clinical attention. However, few empirical studies have addressed this topic using art-making as a tool of emotion expression. This study explores the differences in brain mechanism during the process of expressing anger between patients with schizophrenia and healthy participants using pictographic psychological techniques. We used functional near-infrared spectroscopy to fully detect changes in frontal cortex activity among participants in two groups-schizophrenia and healthy-during the process of experiencing and expressing anger. The results showed that there were no differences in the experience of anger between the two groups. In the process of anger expression, the dorsolateral prefrontal cortex, frontal pole, and other regions showed significant negative activation among patients with schizophrenia, which was significantly different from that of the healthy group. There were significant differences between patients with schizophrenia and the healthy group in the drawing features, drawing contents, and the ability to describe the contents of their drawings. Moreover, the effect size of the latter was greater than those of the former two. In terms of emotion expression, the drawing data and brain activation data were significantly correlated in each group; however, the correlation patterns differed between groups.

Abstract
The present work addresses the identification and qualitative assessment of errors that appear in a free-drawn clock-drawing test representing the time 8:20 in a sample of 455 children and adolescents with neurological diseases and their controls. The authors sought to verify whether the occurrence of particular errors in the clock drawings significantly differentiates the clinical groups. For statistical evaluation of the results, we applied correspondence analysis and cluster analysis. The results of the study showed that three types of errors played an important role in the differentiation of the groups: spatial neglect, mirror reflection, and phonological depletion.

Abstract
The purpose of this study was to examine the reliability and validity of the Executive Function Performance Test (EFPT) in a schizophrenic population. Participants were 30 individuals with the acute phase of schizophrenia and 31 with the chronic stage. Internal consistency using Cronbach's alpha was high (α = .88). Two-way multiple analysis of covariance revealed that the acute group scored significantly higher than the chronic group on almost all tasks and components of the EFPT ( p = .045 to .000), supporting construct validity. Moderate to high Spearman correlation coefficients were found between the total EFPT score and the total Behavioral Assessment of the Dysexecutive Syndrome profile and standardized scores within each of the groups ( r =.433 to .764; p < .017 to .000), supporting criterion validity. The findings support the use of the EFPT for identifying executive functions in the context of everyday life and instrumental activities of daily living tasks. However, further studies are needed in different populations and cultures.

Abstract
The clock-drawing test (CDT) is used widely to evaluate cognitive disorders, but its role in the assessment of psychotic disorders has not been studied. We sought to examine whether the CDT plays a role as an indicator of psychosis and to establish its sensitivity to clinical improvement of psychosis. The CDT was administered twice to 53 hospitalized patients without dementia but with psychosis: once at admission and again before discharge. The CDT scores were calculated in a random order by two independent senior psychiatrists who were blinded to the patients' status (admission or discharge). The inter-rater reliability was high (0.89 at admission, 0.85 at discharge, P<0.01 for both). The severity of psychosis was assessed by the Positive and Negative Syndrome Scale (PANSS). Patients had significantly lower CDT scores at admission than at discharge (2.87±1.39 vs. 3.91±1.08, respectively, P<0.01). The PANSS-total score of the patients showed a significant improvement (84.90±17.77 vs. 69.18±16.23, P<0.01). An inverse correlation was found between CDT performance and psychosis severity, as reflected by the PANSS-positive symptom subscale at admission (R=-0.279, P<0.05). Our findings suggest that the CDT may aid in the assessment of psychotic states and in their clinical monitoring.

Abstract
BACKGROUND The Mini-Mental State Examination (MMSE) is widely used in schizophrenia, although normative data are lacking in this population. This review and meta-regression analysis studies the effect of aging on MMSE scores in schizophrenic patients. METHODS We entered the search terms schizophrenia and MMSE in PubMed and PsychInfo. Bibliographies of pertinent articles were also examined. We included every study presenting the MMSE scores in schizophrenic patients along with a corresponding mean age. We conducted our analyses using simple linear regression weighted for the inverse of within-trial variance of the age variable, thus conferring more importance to studies with narrower age groups. RESULTS We identified 56 articles (n = 5,588) published between 1990 and 2012. The MMSE scores of schizophrenic patients decline by approximately 1 point for every four years (y = 34.939-0.247x, 95% Confidence Interval (CI) [-0.304, -0.189], R 2 = 0,545), which is five times the rate in the general population. Institutionalized patients account for a large proportion of this decline (y = 37.603-0.308x, 95% CI [-0.349, -0.267], R 2 = 0.622) whereas community-dwelling patients are relatively stable throughout aging (y = 27.591-0.026x, 95% CI [-0.074, 0.023], R 2 = 0.037). CONCLUSIONS Subgroup analyses show different trajectories between institutionalized and outpatients with schizophrenia. The deterioration observed in institutionalized patients may have to do with greater illness severity, heavier medication load, vascular risk factors, and lack of stimulation in institutional settings. Studies documenting the role of these variables would be useful. Cognitive screening tools that assess executive functions would be interesting to study in schizophrenics, as they may reveal more subtle age-related cognitive changes not measured by the MMSE.

Abstract
BACKGROUND In recent decades there has been an increasing interest in cognitive deficits in schizophrenia. However, only a few studies have examined the impact of psychosocial support on the prevention of cognitive deterioration in patients who suffer from schizophrenia. AIM The aims of the present study are: (1) to confirm the presence of cognitive deficits among patients with schizophrenia; (2) to explore any correlations between such deficits and a range of clinical and/or demographic characteristics of the patients; and (3) to investigate any association between cognitive deficits and psychosocial support. METHOD A total of 118 patients with schizophrenia (the patient group) and 102 healthy volunteers (the control group) had a cognitive assessment using a battery of neuropsychological tests. The patients were allocated to one of the following groups: (1) patients under routine outpatient follow-up; or (2) patients receiving or having recently received intensive psychosocial support, in addition to follow-up. This included daily participation in vocational and recreational activities provided by dedicated mental health day centers. The findings of the neuropsychological testing of individuals in all groups were compared, after controlling for clinical or demographic factors. RESULTS The scores in the neuropsychological tests were lower overall in the patients group compared to healthy volunteers. Within the patients group, those receiving/having received psychosocial support had higher scores compared to those on routine follow-up alone. There were no significant differences between patients currently receiving psychosocial support and those having received it in the past. Lower education, age and illness duration (but not severity of positive or negative symptoms) were factors associated with lower test scores. CONCLUSIONS The study provides some evidence that psychosocial support may be beneficial for the cognitive functioning of patients with schizophrenia and this benefit may be a lasting one.

Abstract
OBJECTIVE The clock drawing test (CDT) is a widely used cognitive screening tool that has been well accepted among clinicians and patients for its ease of use and short administration time. Although there is ample interest in the CDT as a screening instrument, there remains a range of CDT administration and scoring systems with no consensus on which system produces the most valid results while remaining user friendly. The aims of this review are to synthesize the available evidence on CDT scoring systems' effectiveness and to recommend which system is best suited for use at the clinical frontlines. DESIGN A Pubmed literature search was carried out from 2000 to 2013 including manual cross-referencing of bibliographies in order to capture studies published after Shulman's comprehensive review published in 2000. A brief summary of all original scoring systems is included, as well as a review of relevant comparative studies. RESULTS The consensus from multiple comparison studies suggests that increasing the complexity of CDT scoring systems does little to enhance the test's ability to identify significant cognitive impairment. Moreover, increased complexity in scoring adds to the administration time, thereby reducing the test's utility in clinical settings. CONCLUSIONS In comparing scoring systems, no system emerged as consistently superior in terms of predictive validity. The authors conclude that when scoring the CDT as a screening instrument in a primary/general medicine/community setting, simpler is better, and perhaps qualitative assessment of "normal" versus "abnormal" may be sufficient for screening purposes and the establishment of a baseline for follow-up.

Abstract
BACKGROUND There has been a growing need for a cognitive assessment tool that can be used for older adults with schizophrenia in clinical settings. The clock-drawing test (CDT) is a brief cognitive test that covers a wide range of cognitive function. Although it is widely used to assess patients with dementia, limited data are available on its usefulness in older patients with schizophrenia. Thus, we investigated the psychometric properties of the CDT and their relationship with life functions to examine the test's usefulness for assessing cognitive function in older adults with schizophrenia. METHODS Seventy-three older adults with chronic schizophrenia who had been hospitalized for over 1 year participated in the study. We adopted the executive clock-drawing task for administration and scoring of the CDT, which consists of free-drawn and copy conditions. The Mini-Mental State Examination and the Brief Assessment of Cognition in Schizophrenia were administered. Symptom severity and life functions were assessed with the Positive and Negative Syndrome Scale and the Life Skills Profile, respectively. RESULTS Both free-drawn and copy scores significantly correlated with the Mini-Mental State Examination score and the Brief Assessment of Cognition in Schizophrenia composite score. These scores also significantly correlated with symptom severity and length of current hospitalization. Stepwise regression analysis showed that only the copy score, together with symptom severity, predicted the Life Skills Profile score. CONCLUSIONS The CDT can assess cognitive function in older adults with schizophrenia. Moreover, CDT performance is associated with life functions independent from other clinical variables. These results suggest that the CDT is a useful cognitive assessment tool for this population.

Abstract
OBJECTIVE The Clock Drawing Test (CDT) is commonly used for cognitive screening, but there are few studies that compare performance on the CDT among schizophrenic patients of different ages. The objective of this study was to investigate the influence of schizophrenia and aging on performance in the CDT. METHOD Schizophrenic patients (N = 244) and a comparison group (N = 875) were recruited as subjects. Freedman's CDT was completed by all subjects, and the influences of disease and aging on performance in the CDT were examined. Multiple comparisons of the CDT scores between patients and the comparison group and within three age subgroups (young: less than 40 years, middle aged: 40-59 years, elderly: more than 60 years) were performed. RESULTS There was a significant interaction of diagnosis and age, and the education significantly influenced the total score for all CDT conditions. For almost all age subgroups of patients, individuals with schizophrenia had significantly lower scores on all the CDT conditions than did the comparison group subjects. For patients and the comparison group, the elderly subgroup performed significantly worse than the young and middle-aged subgroups on almost all conditions of the CDT. Qualitative analysis of the clocks drawn revealed that the number of CDT categories in which schizophrenic patients scored significantly lower than the comparison group tended to increase with aging across both groups. CONCLUSIONS This study suggests that performance on the CDT was impaired not only by disease but also by aging. The study confirms that the CDT is sensitive enough to screen for cognitive impairments in schizophrenia.

Abstract
OBJECTIVES The Clock Drawing Test (CDT) is commonly used for cognitive screening. The purpose of this study is to develop normative data for the CDT for the Japanese community-dwelling population, using the method of Freedman. This study also investigates the effect of demographic factors on the performance of the subjects in this task. METHODS We administered the CDT and the Mini-Mental State Examination (MMSE) to 873 volunteers. Using a multiple linear regression analysis, we found a gender difference in the free-drawn condition. RESULTS A detrimental effect of age was observed in the free-drawn and pre-drawn conditions. The years of education affected the CDT in the examiner 2 condition. Correlations of the MMSE with each of the five conditions of the CDT were significant, further validating this test. CONCLUSIONS Our study provides preliminary normative data for the Japanese population stratified by the age and level of education. However, interpretation of our results was hampered by the large variability in the performance of the subjects and the possibility of a selection bias. Thus, additional studies will be necessary to further characterise the CDT scores for the Japanese community.

Abstract
BACKGROUND Symptom rating scales are now well established in schizophrenia research but their scores are not the same as outcome. AIMS To appraise the usefulness of symptom rating scales in evaluating the outcome of people with schizophrenia. METHOD Literature on the use of the Brief Psychiatric Rating Scale (BPRS) the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression (CGI) in schizophrenia research was studied. RESULTS Scales were designed to make diagnoses, to categorise patients, syndromes or both, and to demonstrate antipsychotic efficacy, as well as to measure outcome. There is much redundancy both between and within scales. Early work suggests limited concurrent validity with external outcome variables. Data are at best ordinal and there are particular difficulties in equating outcome with percentage changes in scores. The concept of remission, which uses absolute item score thresholds with a duration criterion, is a promising outcome measure. CONCLUSIONS Symptom rating scale scores can only comprise a limited part of outcome measurement. Standardised remission criteria may present advantages in outcome research.

Abstract
Cognitive impairment is common to both schizophrenia and alcoholism. Despite increasing recognition that people with both disorders represent a problematic client group, little is known about the possible additive effect of a dual diagnosis upon impaired cognitive function. This study investigates impairment of cognitive functioning in patients with schizophrenia, alcohol dependence, or a dual diagnosis of schizophrenia and alcohol use disorder. It was hypothesised that patients with dual diagnosis would show greater cognitive impairment than those with a single diagnosis. The Mini-Mental State Examination (MMSE) and standardised measures of psychiatric health and substance use were administered to 120 community psychiatric patients with a diagnosis of schizophrenia, alcohol dependence and both conditions (dual diagnosis). Higher rates of cognitive impairment were found among dual diagnosis patients compared to the schizophrenia or alcohol patients. This was shown in age-adjusted measures of global functioning, and on the tests of language, reading and writing, and visuospatial construction. Despite its common usage, global MMSE scores were insensitive to the cognitive impairments typically found in these clinical groups. Where the MMSE is used as a screening tool, it is recommended that scores are adjusted for the effects of age.

Abstract
Schizophrenia is a common psychiatric condition, affecting approximately 1% of the population. Acute emergent presentations often include hallucinations, delusions, thought, and speech disorders. Agitation is common among emergency patients with schizophrenia. Decisional capacity should be assessed in all patients. Reversible causes of agitation should be ruled out, including infection, metabolic disorders, endocrine disorders, trauma, pain, noncompliance, toxicological disorders, and structural brain abnormalities. Agitation may be managed acutely using a combination of pharmacological agents and nonpharmacological interventions. Effective pharmacological agents include several classes of antipsychotic agents and benzodiazepines. Potential life-threatening complications of pharmacological therapy should be anticipated, which may include neuroleptic malignant syndrome (NMS), prolonged QT syndrome, and respiratory depression. Nonpharmacological interventions may include a quiet environment, physical restraints, and behavioral interventions. Disposition decisions should be made based on the etiology of agitation, effective management, decisional capacity, and presence of suicidal or homicidal intentions. Many patients who have required nonpharmacological or pharmacological management of agitation require inpatient psychiatric treatment, either voluntarily or involuntarily. Psychiatric consultation should be sought for patients with schizophrenia and uncertain disposition determinations, or those requiring other complex management decisions.
