BACKGROUND Paranoia is an unregarded but pervasive attribute of human populations. In this study we carried out the most comprehensive investigation so far of the demographic, economic, social and clinical correlates of self-reported paranoia in the general population. METHOD Data weighted to be nationally representative were analysed from the Adult Psychiatric Morbidity Survey in England (APMS 2007; n=7281). RESULTS The prevalence of paranoid thinking in the previous year ranged from 18.6% reporting that people were against them, to 1.8% reporting potential plots to cause them serious harm. At all levels, paranoia was associated with youth, lower intellectual functioning, being single, poverty, poor physical health, poor social functioning, less perceived social support, stress at work, less social cohesion, less calmness, less happiness, suicidal ideation, a great range of other psychiatric symptoms (including anxiety, worry, phobias, post-traumatic stress and insomnia), cannabis use, problem drinking and increased use of treatment and services. CONCLUSIONS Overall, the results indicate that paranoia has the widest of implications for health, emotional well-being, social functioning and social inclusion. Some of these concomitants may contribute to the emergence of paranoid thinking, while others may result from it.

BACKGROUND Evidence is accumulating that child sexual abuse (CSA) is associated with many psychiatric disorders in adulthood. This paper uses the detailed information available from the 2007 Adult Psychiatric Morbidity Survey of England (APMS 2007) to quantify links between CSA and a range of psychiatric conditions. METHOD The prevalence of psychiatric disorder was established in a random sample of the English household population (n=7403), which also provided sociodemographic and experiential information. RESULTS We analyzed six types of common mental disorder, alcohol abuse and drug abuse, and people who screened positively for post-traumatic stress disorder (PTSD) and eating disorders. All were strongly and highly significantly associated with CSA, particularly if non-consensual sexual intercourse was involved, for which odds ratios (ORs) ranged from 3.7 to 12.1. These disorders were also related to adult sexual abuse (ASA), although the likelihood of reverse causality is then increased. Revictimization in adulthood was common, and increased the association of CSA with disorder. For several disorders, the relative odds were higher in females but formal tests for moderation by gender were significant only for common mental disorders and only in relation to non-consensual sexual intercourse. The population attributable fraction (PAF) was higher in females in all cases. CONCLUSIONS The detailed and high-quality data in APMS 2007 provided important confirmation both of the strength of association of CSA with psychiatric disorder and of its relative non-specificity. Our results have major implications at the public health level and the individual level, in particular the need for better recognition and treatment of the sequelae of CSA.

BACKGROUND Economic recessions are characterized by job insecurity and rising unemployment. The relationship between job insecurity and poor mental health is known. However, we do not know how this relationship is affected by individual socio-economic circumstances. METHOD A random probability sample comprising 3581 respondents (1746 men and 1835 women) were selected from the third national survey of psychiatric morbidity in Great Britain. Fieldwork was carried out throughout 2007. Depression was assessed using the revised Clinical Interview Schedule and ICD-10 research diagnostic criteria administered by well-trained lay interviewers. RESULTS One-fifth of all working men and women aged 16-64 years felt that their job security was poor. From a multivariate analysis of several job stressors, there was an increased likelihood of depression among those agreeing that their job security was poor [odds ratio (OR) 1.58, 95% confidence intervals (CI) 1.22-2.06, p<0.001]. After controlling for age and sex, job insecurity (OR 1.86, 95% CI 1.47-2.35, p<0.001) and being in debt (OR 2.17, 95% CI 1.58-2.98, p<0.001) were independently associated with depression. CONCLUSIONS Job insecurity has a strong association with feelings of depression even after controlling for biographic characteristics (age and sex), economic factors (personal debt) and work characteristics (type of work and level of responsibility). Despite the organizational changes needed to cope with a recession, employers should also take note of the additional distress experienced by workers at a time of great uncertainty, particularly those in less skilled jobs and in financial straits.

BACKGROUND Personal debt is one of many factors associated with anxiety, depression and suicidality. The aim of this study was to examine the relationship between personal debt and suicidal ideation in the context of sociodemographic factors, employment and income, lifestyle behaviours, and recently experienced traumatic events. METHOD Interviews were conducted with a random probability sample comprising 7461 respondents for the third national survey of psychiatric morbidity of adults in England. Fieldwork was carried out throughout 2007. The prevalence of suicidal thoughts in the past week, past year and lifetime was assessed and current sources of debt were recorded. RESULTS In 2007, 4.3% of adults in England had thought about taking their own life in the past 12 months, ranging from 1.8% of men aged ≥ 55 years to 7.0% of women aged 35-54 years. Those in debt were twice as likely to think about suicide after controlling for sociodemographic, economic, social and lifestyle factors. Difficulty in making hire purchase or mail order repayments and paying off credit card debt, in addition to housing-related debt (rent and mortgage arrears), was strongly associated with suicidal thoughts. Feelings of hopelessness partially mediated the relationship between debt and suicidal ideation. CONCLUSIONS The number of debts, source of the debt and reasons for debt are key correlates of suicidal ideation. Individuals experiencing difficulties in repaying their debts because they are unemployed or have had a relationship breakdown or have heavy caring responsibilities may require psychiatric evaluation in addition to debt counselling.

OBJECTIVES Individuals who are out of work have a higher rate of common mental disorders (CMD) than individuals who are employed. People who are unemployed in the UK are entitled to welfare benefits to alleviate financial strain. This study examined rates of CMD in individuals who were employed, unemployed and receiving various UK benefits. It also investigated associations between duration of unemployment, gender and CMD. STUDY DESIGN An analysis of 5090 working-age participants from the Adult Psychiatric Morbidity Survey 2007, a stratified probability sample survey conducted among adults aged 16 years and over living in private households in England. METHODS CMD was assessed using the Clinical Interview Schedule (Revised). Information was gathered on sociodemographics, employment, income, benefits and debt. Data were analysed using logistic regression. RESULTS Risk of CMD was significantly greater in individuals classified as: unemployed; economically inactive; not working due to physical health reasons; unable to find a suitable job; receiving housing, care or sickness benefit; and receiving income support. However, risk of CMD was not significantly greater in individuals receiving jobseekers allowance. Individuals unemployed for less than 1 year or more than 3 years had a higher risk of CMD. Some interactions with gender were significant, with associations being greater in men than women. CONCLUSIONS Job loss events are not the only reason for unemployed people to develop CMD. The state of unemployment itself may be detrimental to mental health. Risk of CMD is increased in those who have been out of work for 3 years or more. Associations between benefits and mental health are likely to be due to social, health or economic circumstances associated with benefit eligibility.

BACKGROUND There is concern surrounding the psychological health and uptake of treatment services among veterans of the UK Armed Forces. METHOD Data from a cross-sectional, nationally representative sample were used to compare health outcomes and treatment seeking among 257 post-national service veterans aged 16-64 years and 504 age and sex frequency-matched non-veterans living in the community in England. Early leavers (<4 years service) were compared with longer serving veterans. RESULTS Male veterans reported more childhood adversity and were more likely to have experienced a major trauma in adulthood than non-veterans. There was no association between any measure of mental health and veteran status in males, except reporting more violent behaviours [adjusted odds ratio (aOR) 1.44, 95% confidence interval (CI) 1.01-2.06]. In females, a significant association was found between veteran status and ever having suicidal thoughts (aOR 2.82, 95% CI 1.13-7.03). No differences in treatment-seeking behaviour were identified between veterans and non-veterans with any mental disorder. Early service leavers were more likely to be heavy drinkers (aOR 4.16, 95% CI 1.08-16.00), to have had suicidal thoughts (aOR 2.37, 95% CI 1.21-4.66) and to have self-harmed (aOR 12.36, 95% CI 1.61-94.68) than longer serving veterans. CONCLUSIONS The findings of this study do not suggest that being a veteran is associated with adversity in terms of mental health, social disadvantage or reluctance to seek treatment compared with the general population. Some evidence implies that early service leavers may experience more mental health problems than longer-serving veterans.

Common mental disorders, unemployment and psychosocial job quality: is a poor job better than no job at all?

Peter Butterworth; Liana S. Leach; Samuel P. McManus; Stephen Stansfeld

BACKGROUND Employment is associated with health benefits over unemployment, but the psychosocial characteristics of work also influence health. There has, however, been little research contrasting the prevalence of psychiatric disorders among people who are unemployed with those in jobs of differing psychosocial quality. METHOD Analysis of data from the English Adult Psychiatric Morbidity Survey (APMS) considered the prevalence of common mental disorders (CMDs) among 2603 respondents aged between 21 and 54 years who were either (i) employed or (ii) unemployed and looking for work at the time of interview in 2007. Quality of work was assessed by the number of adverse psychosocial job conditions reported (low control, high demands, insecurity and low job esteem). RESULTS The prevalence of CMDs was similar for those respondents who were unemployed and those in the poorest quality jobs. This pattern remained after controlling for relevant demographic and socio-economic covariates. CONCLUSIONS Although employment is thought to promote mental health and well-being, work of poor psychosocial quality is not associated with any better mental health than unemployment. Policy efforts to improve community mental health should consider psychosocial job quality in conjunction with efforts to increase employment rates.

Background The present study aimed to assess the prevalence of common mental disorders (CMDs) by occupation in a representative sample of the English adult population. Another aim was to examine whether the increased risk of CMD in some occupations could be explained by adverse work characteristics. Method We derived a sample of 3425 working-age respondents from the Adult Psychiatric Morbidity Survey 2007. Occupations were classified by Standard Occupational Classification group, and CMD measured by the Revised Clinical Interview Schedule. Job characteristics were measured by questionnaire, and tested as explanatory factors in associations of occupation and CMD. Results After adjusting for age, gender, housing tenure and marital status, caring personal service occupations had the greatest risk of CMD compared with all occupations (odds ratio 1.73, 95% confidence interval 1.16–2.58). The prevalence of adverse psychosocial work characteristics did not follow the pattern of CMD by occupation. Work characteristics did not explain the increased risk of CMDs associated with working in personal service occupations. Contrary to our hypotheses, adding work characteristics individually to the association of occupation and CMD tended to increase rather than decrease the odds for CMD. Conclusions As has been found by others, psychosocial work characteristics were associated with CMD. However, we found that in our English national dataset they could not explain the high rates of CMD in particular occupations. We suggest that selection into occupations may partly explain high CMD rates in certain occupations. Also, we did not measure emotional demands, and these may be important mediators of the relationship between occupation type and CMDs.

The Synthesis of Aminoalcohols from Epoxides and Ammonia

Samuel P. McManus; Charles A. Larson; Richard A. Hearn

Abstract In connection with another problem we had need for some simple aminoalcohols which were not commercially available. While textbooks make the reaction of ammonia and amines with epoxides appear inviting for the preparation of aminoalcohols, an examination of the literature yielded surprisingly few clearly written examples of the reactions of ammonia with epoxides and many of the good examples had undesirable features. For instance, one of the aminoalcohols desired was threo-3-amino-2-butanol. Lucas et al2. reported an improved synthesis of this compound in 76% yield by reacting the meso-epoxide with an excess of concentrated aqueous ammonia. The drawbacks to their synthesis were the long recommended reaction time (10 days) and the large volume of water to be removed by distillation (about 2 liters per mole of product obtained). While the yield is reasonably good, all other examples of the reaction that we have found report lower yields (18–70%). Malinovski3 has reviewed the general reaction and tr...

Age and birth cohort differences in depression in repeated cross-sectional surveys in England: the National Psychiatric Morbidity Surveys, 1993 to 2007.

Nicola Spiers; T Brugha; Paul Bebbington; Samuel P. McManus; R Jenkins; Howard Meltzer

BACKGROUND The National Psychiatric Morbidity Survey (NPMS) programme was partly designed to monitor trends in mental disorders, including depression, with comparable data spanning 1993 to 2007. Findings already published from this programme suggest that concerns about increasing prevalence of common mental disorders (CMDs) may be unfounded. This article focuses on depression and tests the hypothesis that successive birth cohorts experience the same prevalence of depression as they age. METHOD We carried out a pseudo-cohort analysis of a sequence of three cross-sectional surveys of the English household population using identical diagnostic instruments. The main outcome was ICD-10 depressive episode or disorder. Secondary outcomes were the depression subscales of the Clinical Interview Schedule - Revised (CIS-R). RESULTS There were 8670, 6977 and 6815 participants in 1993, 2000 and 2007 respectively. In men, the prevalence of depression increased between cohorts born in 1943-1949 and 1950-1956 [odds ratio (OR) 2.5, 95% confidence interval (CI) 1.4-4.2], then remained relatively stable across subsequent cohorts. In women, there was limited evidence of change in prevalence of depression. Women born in 1957-1963, surveyed aged 44-50 years in 2007, had exceptionally high prevalence. It is not clear whether this represents a trend or a quirk of sampling. CONCLUSIONS There is no evidence of an increase in the prevalence of depression in male cohorts born since 1950. In women, there is limited evidence of increased prevalence. Demand for mental health services may stabilize or even fall for men.
