Age–period–cohort analysis of the incidence of schizophrenia in Scotland
Authors: Takei Noriyoshi , Lewis Glyn , Sham Pak C. , Murray Robin M. 
Published: July 2009

SynopsisStudies examining a possible decline in the incidence of schizophrenia over the last two to three decades have paid little attention to the possible role of birth cohort effects. We collected data on a Scottish national sample of all schizophrenic patients, admitted for the first time between 1966 and 1990 (N = 11348; male = 6301). In an Age–Period–Cohort analysis, a full model, incorporating three factors, had a substantially better fit to the data than other models (especially, an Age–Period model), providing clear evidence of the presence of a cohort effect. After adjustment for the effects of age and period, there was a 55% reduction in the rate of schizophrenia in men and a 39% fall in the number of women over the 50-year birth period from 1923 to 1973. The marked decline in the first admission rates observed in Scotland cannot, however, be attributed entirely to this cohort effect. Rather, a greater proportion of the declining first admission rates (88%) is ascribed to the period effect (i.e. artefactual or causally related cross-sectional effects). Nevertheless, the fact that a birth-cohort effect accounts for part of the declining incidence, suggests that causal environmental factors operating early in life have been diminishing in intensity.
Prevalence of psychiatric morbidity in the adult population of a rural South African village

Published: July 2009

SynopsisWe report on the first South African two-stage community prevalence study of psychiatric morbidity, conducted in Mamre, a rural ‘coloured’2 village, 50 km from Cape Town. Randomly selected adults (N = 481) were assessed using the Self-Reporting Questionnaire (SRQ) as a first-stage screen and the Present State Examination (PSE-9) was administered to a proportion of the sample (N = 121) as the second-stage criterion. Demographic, health care utilization, and substance abuse data were also collected. Using the PSE-9 CATEGO Index of Definition of 5, the weighted prevalence of psychiatric morbidity was 27·1 % (confidence interval of 19·5−34·7 %), the majority of cases being given a tentative diagnosis of depressive or anxiety disorder. The CATEGO algorithm may not be fully appropriate in this cultural context as there was an apparent overdiagnosis of paranoid states. The SRQ's weighted sensitivity and specificity were 0·49 and 0·82 respectively. Overall, the SRQ correctly identified 67% of cases and non-cases. No demographic variables predicted psychiatric morbidity, but there was an indirect link between morbidity and primary care utilization. Further South African studies of the validity of both the SRQ and of criterion instruments are needed. These may contribute to knowledge regarding cultural factors affecting psychiatric diagnosis.
Pre-morbid asociality in neuroleptic-resistant and neuroleptic-responsive schizophrenia
Authors: Findling R. L. , Jayathilake K. , Meltzer H. Y. 
Published: July 2009

SynopsisThe purpose of this study was to evaluate whether childhood and adolescent premorbid asociality differed in neuroleptic-responsive and neuroleptic-resistant schizophrenia. Premorbid asociality was assessed with the Pre-morbid Asociality Adjustment Scale in 411 patients meeting DSM-III-R criteria for chronic schizophrenia or schizoaffective disorder categorized as being either neuroleptic-responsive or neuroleptic-resistant. Patterns of childhood and adolescent asociality were found to be different in neuroleptic-resistant and neuroleptic-responsive patients. Pre-morbid asociality during the pre-adult years was not consistently worse in patients with poor response to neuroleptic treatment. Greater impairment in late adolescent psychosexual functioning was predictive of poor outcome with regard to neuroleptic treatment.
Patterns of DSM-III-R alcohol dependence symptom progression in a general population survey
Authors: Nelson C. B. , Little R. J. A. , Heath A. C. , Kessler R. C. 
Published: July 2009

SynopsisAge of onset reports obtained retrospectively for each symptom of DSM-III-R alcohol dependence (AD) are used to study patterns of lifetime symptom progression in a large general-population survey of people in the United States. It is shown that symptom progression among a substantial majority of respondents can be summarized as movement across three clusters. Cluster A is defined by symptoms of role impairment/hazardous use (A4), use despite social, psychological or physical problems (A6), and drinking larger amounts or over a longer period of time than intended (A1). Cluster B is defined by tolerance (A7) and impaired control (A2, A3). Cluster C is defined by withdrawal (A8, A9) and giving up activities in order to drink (A5). Clusters are shown to follow a time sequence, with at least one symptom in Cluster A usually occurring first, followed by symptoms in Clusters B and C. In all, 83·4% of the symptom cluster transitions estimated from retrospective age of onset reports are consistent with this progression. Progression to AD is differentially predicted by symptom profiles reported at the age of first symptom onset, with persons reporting Cluster C symptoms most likely to progress subsequently to AD. Furthermore, profiles of AD defined by the highest symptom cluster present at AD onset are differentially predicted by prior personal and parental histories of psychopathology and, among men, are predictive of diagnosis persistence.
A longitudinal study of factors predicting change in cognitive test scores over time, in an older hypertensive population
Authors: Prince M. , Lewis G. , Bird A. , Blizard R. , Mann A. 
Published: July 2009

SynopsisThis study aims to describe factors associated with cognitive decline among 2584 subjects, aged 65–74, who were followed up for 54 months in the Medical Research Council Elderly Hypertension Trial (1982–1989). The subjects completed a cognitive test, the Paired Associate Learning Test (PALT), five times over this period. Decline on the PALT was associated with advanced age, male sex, rural residence, depression and low intelligence. These effects were modified by gender and level of pre-morbid intelligence. Advanced age, rural residence and number of cigarettes smoked daily were only associated with PALT decline among women of below median intelligence. The association between depression and PALT decline was only apparent in women of below median intelligence and men of above median intelligence. While these findings are consistent with other research into cognitive decline, they differ in some ways from reported risk factors for dementia, suggesting aetiological separateness. That women were more vulnerable than men to the effects of age and smoking raises the question of the impact on cognition of accelerated atherosclerosis after the menopause.
Infant growth in the context of maternal eating disorders and maternal depression: a comparative study
Authors: Stein A. , Murray L. , Cooper P. , Fairburn C. G. 
Published: July 2009

SynopsisThere is evidence of growth faltering in infants of mothers with eating disorders. The aim of the current study was to examine whether this is a specific relationship. Thus, the infants of mothers with eating disorders were compared with infants of mothers with post-natal depression and a large comparison group. This study also aimed to explore possible mechanisms whereby growth disturbance comes about.It was found that the infants of mothers with eating disorders were smaller, both in terms of weight for length and weight for age, than either comparison group infants or infants of mothers with post-natal depression. There was little evidence, however, that mothers with eating disorders preferred smaller children or were dissatisfied with their children's shape or that they misperceived their children's size. On the contrary these mothers seemed highly sensitive to their children's shape and, compared with the other two groups, were more likely to judge their children's size accurately. None of these maternal measures significantly predicted the child's growth.The mechanism whereby growth disturbance arises in the context of eating disorders does not appear to be by means of a direct extension of the maternal psychopathology to the infant.
Relationships between age and symptom severity among women seeking medical treatment for premenstrual symptoms
Authors: Freeman E. W. , Rickels K. , Schweizer E. , Ting T. 
Published: July 2009

SynopsisAge at the time of seeking treatment for premenstrual symptoms (PMS) was examined in a sample of 332 women who reported severe distress and met criteria for Late Luteal Phase Dysphoric Disorder (LLPDD). The mean age of the sample was 33·1 (±5·3) years. Severity of symptoms decreased with age and was not associated with the duration of symptoms. Depression-related factors were associated with the severity of PMS, and together with the duration of symptoms, were the best discriminators between the younger (ages 20–35) and older (ages 36–44) women in this sample. These data suggest that the years of the late twenties through mid-thirties are the most vulnerable time for distressing PMS and fail to support the clinical premise that PMS worsens with age until menopause. Further longitudinal study should be conducted to confirm and extend these findings.
Cerebral hemispheric asymmetry revisited: effects of handedness, gender and schizophrenia measured by radius of gyration in magnetic resonance images
Authors: Bullmore E. , Brammer M. , Harvey I. , Murray R. , Ron M. 
Published: July 2009

SynopsisAbnormal patterns of cerebral hemispheric asymmetry have been inconsistently reported in association with schizophrenia. Radius of gyration (Rg) is a measure of the mean dispersion of points in a radially organized structure about that structure's centre of gravity. We developed computerized methods for estimating Rg of the magnetic resonance image (MRI) boundary between cortex and subcortex, and applied these methods to measurement of cerebral hemispheric asymmetry in 37 schizophrenics (SZs) and 30 controls (CONs). In right-handed CONs, Rg of right brain boundaries was significantly greater than Rg of left brain boundaries; in left-handed CONs, Rg of left brain boundaries was significantly greater than Rg of right brain boundaries. In right-handed males (both SZ and CON), there were significant differences in Rg between hemispheres; whereas in females (both SZ and CON) there were no such differences. Right-handed male SZs (N = 26) were distinguished by reversal of the right-handed male CON pattern of interhemispheric difference in Rg, and by global reduction in Rg of right brain boundaries. There was no evidence for significant abnormality of Rg in right-handed female SZs (N = 7). These findings suggest an important interactive effect of gender and schizophrenia on lateralized cerebral structure.
Life events and senile dementia. I. Admission, deterioration and social environment change
Authors: Orrell Martin , Bebbington Paul 
Published: July 2009

SynopsisThis study examines the frequency of life events before admission and before deterioration in 70 dementia patients, in comparison with 50 dementia controls living in the community and 50 fit elderly people matched for age and sex. We hypothesized that there would be an excess of events connoting changes in routine and the social environment. Specific scales were developed to measure these aspects of events. Our results supported the initial hypothesis, confirming that it is the social disruptiveness of change rather than the threat implied by life events that is associated with deterioration. The findings are discussed in the light of current models of the dementia process.
Is early separation anxiety a specific precursor of panic disorder–agoraphobia? a community study
Authors: Silove D. , Harris M. , Morgan A. , Boyce P. , Manicavasagar V. , Hadzi-Pavlovic D. , Wilhelm K. 
Published: July 2009

SynopsisThe present study aimed to examine memories of early separation anxiety symptoms in a community sample of women at heightened risk to neurotic disorder. The chief finding was that subjects with a lifetime history of panic disorder–agoraphobia (PD–Ag) returned statistically higher scores on a retrospective measure of early separation anxiety compared to subjects with either generalized anxiety or other phobic disorders, a result which was not accounted for by differences in neuroticism or General Health Questionnaire scores. Although limited by its retrospective design and the problem of co-morbidity in subclassifying the anxiety disorders, the present study does provide added support for the hypothesis – endorsed by DSM-III-R – that there is a developmental link between early separation anxiety and panic disorder.
Cognitive dysfunction in schizophrenia followed up over 5 years, and its longitudinal relationship to the emergence of tardive dyskinesia
Authors: Waddington John L. , Youssef Hanafy A. , Kinsella Anthony 
Published: July 2009

SynopsisIn this study, 51 chronic schizophrenic in-patients were evaluated for a range of demographic, clinical and medication variables, and followed up over five years. There was no significant overall change in cognitive function in this patient group as a whole, suggesting the absence of active disease at this stage of the illness. The only correlate of individual instances of cognitive deterioration over the study period was the emergence of new cases of tardive buccal-lingual-masticatory but not of limb-trunkal dyskinesia, and the greater severity of such movement disorder. A positive family history was also identified prospectively as a predictor of the emergence of tardive dyskinesia in chronic schizophrenia.
Families coping with schizophrenia: coping styles, their origins and correlates
Authors: Birchwood Max , Cochrane Raymond 
Published: July 2009

SynopsisAn analysis of the coping styles adopted by relatives of schizophrenic patients has been identified by many reviewers as essential to an understanding of the complex interactions between patient and caregiver and to the origins of relatives' expressed emotion (EE). This study reports a taxonomy of coping behaviour derived from interviews with relatives of schizophrenic patients. It was found that relatives adopted broad styles of coping across all areas of patients' behaviour change. Relationships were uncovered between the styles and (a) relatives perceived control, burden and stress, (b) patients' social functioning, severity of behavioural disturbance and progress of the illness. It is suggested that advising relatives of changes in their coping styles in the course of family intervention must be tempered by an understanding of their origins in patients' behaviour. Further research is recommended to identify the coping styles associated with the high EE/low EE research classification.

An electrophysiological correlate of Eating Attitudes Test scores in female college students
Authors: Wilson Josephine F. , Mercer Joy C. 
Published: July 2009

SynopsisEating Attitudes Test (EAT) scores of forty female college students were compared to their electrodermal activity (EDA) responses when offered a plate of chocolate chip cookies. A significant positive correlation was detected between the EAT scores and the skin conductivity measures associated with the presentation of food. Women with the highest EAT scores also exhibited the greatest sympathetic nervous system responses to a plate of cookies. This finding supports the conclusion that the EAT is capable of identifying individuals who are preoccupied with food or anxious about eating.
Coping with chronic fatigue syndrome: illness responses and their relationship with fatigue, functional impairment and emotional status
Authors: Ray C. , Jefferies S. , Weir W. R. C. 
Published: July 2009

SYNOPSISThe implications of patients' approaches to managing chronic fatigue syndrome were examined in a cross-sectional study. With severity of fatigue controlled, attempting to maintain activity was associated with less functional impairment, while accommodating to the illness was positively related to impairment; behavioural disengagement was related not only to higher levels of impairment but also to greater emotional disturbance. Fatigue itself was positively associated with focusing on symptoms and with behavioural disengagement; it was associated also with illness accommodation, but only for illness of longer duration. The causal direction of relationships between coping and fatigue severity is ambiguous, and a follow-up study will address the effects of coping on changes in the illness over time.
Cognitive dysfunction in chronic schizophrenia followed prospectively over 10 years and its longitudinal relationship to the emergence of tardive dyskinesia
Authors: Waddington John L. , Youssef Hanafy A. 
Published: July 2009

SynopsisBasic cognitive function was assessed at initial and at 5- and 10-year follow-up assessments among 41 primarily middle-aged in-patients manifesting the severest form of schizophrenia; additionally, the presence and severity of tardive dyskinesia was evaluated on each occasion. Overall, there was a modest but significant deterioration in cognitive function over the decade, particularly among older men. Longitudinally, patients with persistent tardive (orofacial) dyskinesia continued to show poorer cognitive function than those consistently without such movement disorder, though within neither group did cognitive function change over the decade. Those patients demonstrating prospectively the emergence of orofacial dyskinesia showed a marked deterioration in their cognitive function over the same time-frame within which their movement disorder emerged, but this decline did not progress further thereafter. There appears to exist some modest, progressive deterioration in cognitive function even late in the chronic phase of severe schizophrenic illness which appears to derive primarily from patients showing de novo emergence of tardive orofacial dyskinesia.
Maladaptive coping and affective disorders among cancer patients
Authors: Parle M. , Jones B. , Maguire P. 
Published: July 2009

SynopsisCoping has attracted much attention in research as a possible mediator of the psychological impact of cancer. Yet, conceptual ambiguity and methodological limitations have resulted in weak and contradictory findings. A major shortcoming has been the use of designs which do not represent adequately the complexity or the diversity of demands which arise from the diagnosis and treatment of cancer. The neglect of appraisal in the assessment of the relationship between coping and mental health is of particular concern, given the role it has been found to play in the onset and maintenance of affective disorders.In a prospective study 673 newly diagnosed cancer patients were interviewed 4 to 8 weeks and 1 year later to assess the effects of their appraisals, coping responses and resolution of any concerns on subsequent mental health. Logistic regression analyses, adjusted for possible confounding variables, were used to investigate the relationships between coping variables and affective disorders. When examined separately the degree of threat appraised, the reporting of a helpless response and perceived success of primary responses in resolving concerns all predicted subsequent affective disorder. However, in a multivariate model only appraisal and success of the response in resolving the concern were significant. No response was found to prevent affective disorders, however certain types of responses were associated with the resolution of specific concerns. The results highlight the importance of assessing the whole coping process and the need to address the complex and multifaceted characteristics of cancer demands. On the basis of our findings we describe a maladaptive cycle of coping, which we believe contributes to the later onset of affective disorders in cancer patients.
Unexplained physical symptoms: outcome, utilization of medical care and associated factors
Authors: Speckens A. E. M. , Van Hemert A. M. , Bolk J. H. , Rooijmans H. G. M. , Hengeveld M. W. 
Published: July 2009

SynopsisThe aim of the study was to investigate the recovery and frequency of physician contact in patients with unexplained physical symptoms and to identify factors associated with persistent disorder. Of 100 consecutive patients who presented with medically unexplained symptoms to a general medical out-patient clinic, 81 participated in a follow-up study. The mean follow-up time was 15·2 months (S.D. 4·0). At follow-up, many of the patients with unexplained physical symptoms reported that they had recovered (30%) or improved (46%) with regard to their presenting symptoms. Female sex and a high number of symptoms predicted a bad outcome in terms of recovery. Persistence of symptoms was not related to the duration of the symptoms, type of presenting complaint or the presence of psychiatric disorder. Forty per cent of patients with unexplained symptoms did not visit their general practitioner on their own initiative in the year following the initial visit to the clinic. Medical care utilization appeared to be associated with female sex, age, number and duration of symptoms, fatigue and psychiatric disorder, especially somatoform disorders. However, the association of a high frequency of physican contact with female sex and psychiatric disorder was not sustained after controlling for possible confounding factors.
The relationship between depression and anxiety: construction of a prototypical anxiety and depression scale
Authors: Koeter Maarten W. J. , Van Den Brink Wim 
Published: July 2009

SynopsisThe question of the relationship between anxiety and depression remains to be solved. The fact that clinical pictures show substantial overlap makes it difficult, using conventional instruments, to distinguish between the co-occurrence of anxiety and depression and overlap in definitions and measurement of the two syndromes. This calls for the construction of scales which exclude symptoms common to both syndromes and incorporate symptoms specific only to anxiety or only to depression; i.e. scales with maximum discriminant validity. This article describes the construction of two such scales based on PSE symptoms; a prototypical anxiety scale and a prototypical depression scale. In a sample of 134 non-psychotic psychiatric out-patients these scales show good reliability and validity, both as a measure of severity and as a screening device. Compared to the Hamilton anxiety and depression scales (HARS and HRSD), the correlation between the prototypical anxiety and depression scales is low.
