The development of a computerized assessment for minor psychiatric disorder

A pandemic toll in frail older adults: Higher odds of incident and persistent common mental disorders in the ELSA-Brasil COVID-19 mental health cohort

INTRODUCTION

We aimed to investigate the association of frailty with persistent and incident common mental disorders (CMD) in older adults during the pandemic.

METHODS

We included 706 older adults who participated in the onsite wave of the ELSA-Brasil study (2017-2019) and the online COVID-19 assessment (May-July 2020). CMD were assessed in both waves by the Clinical Interview Schedule-Revised. Frailty was defined according to the physical phenotype and Frailty Index in the 2017-2019 wave. Logistic regression was used to investigate the association of frailty with persistent and incident CMD, adjusted for sociodemographics.

RESULTS

Frailty according to both definitions were associated with persistent CMD (Frailty Index: OR = 8.61, 95 % CI = 4.08-18.18; physical phenotype: OR = OR = 23.67, 95 % CI = 7.08-79.15), and incident CMD (Frailty Index: OR = 2.79, 95 % CI = 1.15-6.78; physical phenotype OR = 4.37, 95 % CI = 1.31-14.58). The exclusion of exhaustion (that overlaps with psychiatric symptoms) from the frailty constructs did not change the association between frailty and persistent CMD, although the associations with indent CMD were no longer significant.

LIMITATIONS

Fluctuations in CMD status were not captured between both assessments.

CONCLUSION

Frailty status before the COVID-19 outbreak was associated with higher odds of persistent and incident CMD in older adults during the pandemic first wave. Identifying individuals at higher risk of mental burden can help prioritize resources allocation and management.

Prevalence and risk factors of psychiatric symptoms and diagnoses before and during the COVID-19 pandemic: findings from the ELSA-Brasil COVID-19 mental health cohort

BACKGROUND

There is mixed evidence on increasing rates of psychiatric disorders and symptoms during the coronavirus disease 2019 (COVID-19) pandemic in 2020. We evaluated pandemic-related psychopathology and psychiatry diagnoses and their determinants in the Brazilian Longitudinal Study of Health (ELSA-Brasil) São Paulo Research Center.

METHODS

Between pre-pandemic ELSA-Brasil assessments in 2008-2010 (wave-1), 2012-2014 (wave-2), 2016-2018 (wave-3) and three pandemic assessments in 2020 (COVID-19 waves in May-July, July-September, and October-December), rates of common psychiatric symptoms, and depressive, anxiety, and common mental disorders (CMDs) were compared using the Clinical Interview Scheduled-Revised (CIS-R) and the Depression Anxiety Stress Scale-21 (DASS-21). Multivariable generalized linear models, adjusted by age, gender, educational level, and ethnicity identified variables associated with an elevated risk for mental disorders.

RESULTS

In 2117 participants (mean age 62.3 years, 58.2% females), rates of CMDs and depressive disorders did not significantly change over time, oscillating from 23.5% to 21.1%, and 3.3% to 2.8%, respectively; whereas rate of anxiety disorders significantly decreased (2008-2010: 13.8%; 2016-2018: 9.8%; 2020: 8%). There was a decrease along three wave-COVID assessments for depression [β = -0.37, 99.5% confidence interval (CI) -0.50 to -0.23], anxiety (β = -0.37, 99.5% CI -0.48 to -0.26), and stress (β = -0.48, 99.5% CI -0.64 to -0.33) symptoms (all ps < 0.001). Younger age, female sex, lower educational level, non-white ethnicity, and previous psychiatric disorders were associated with increased odds for psychiatric disorders, whereas self-evaluated good health and good quality of relationships with decreased risk.

CONCLUSION

No consistent evidence of pandemic-related worsening psychopathology in our cohort was found. Indeed, psychiatric symptoms slightly decreased along 2020. Risk factors representing socioeconomic disadvantages were associated with increased odds of psychiatric disorders.

Examining the impact of the COVID-19 pandemic through the lens of the network approach to psychopathology: Analysis of the Brazilian Longitudinal Study of Health (ELSA-Brasil) cohort over a 12-year timespan

Cohort studies have displayed mixed findings on changes in mental symptoms severity in 2020, when the COVID-19 pandemic outbreak started. Network approaches can provide additional insights by analyzing the connectivity of such symptoms. We assessed the network structure of mental symptoms in the Brazilian Longitudinal Study of Health (ELSA-Brasil) in 3 waves: 2008-2010, 2017-2019, and 2020, and hypothesized that the 2020 network would present connectivity changes. We used the Clinical Interview Scheduled-Revised (CIS-R) questionnaire to evaluates the severity of 14 common mental symptoms. Networks were graphed using unregularized Gaussian models and compared using centrality and connectivity measures. The predictive power of centrality measures and individual symptoms were also estimated. Among 2011 participants (mean age: 62.1 years, 58% females), the pandemic symptom 2020 network displayed higher overall connectivity, especially among symptoms that were related to general worries, with increased local connectivity between general worries and worries about health, as well as between anxiety and phobia symptoms. There was no difference between 2008 and 2010 and 2017-2019 networks. According to the network theory of mental disorders, external factors could explain why the network structure became more densely connected in 2020 compared to previous observations. We speculate that the COVID-19 pandemic and its innumerous social, economical, and political consequences were prominent external factors driving such changes; although further assessments are warranted.

Prevalence of Alcohol Use Disorders and Their Association with Sociodemographic Determinants and Depression/Anxiety Disorders in a Representative Sample of the Greek General Population

BACKGROUND

Country-level epidemiological data about alcohol-related problems is useful for planning prevention and treatment services. Heavy Alcohol Consumption (HAC) and Alcohol Use Disorder (AUD) are two syndromes of alcohol-related problems that have been recognized worldwide. Study of the epidemiological determinants of HAC and AUD in different sociocultural contexts could inform hypotheses about the etiology or the consequences of alcohol-related problems.

OBJECTIVES

We assessed the prevalence and associations of HAC and AUD with sociodemographic variables adjusting for common mental disorders in a representative sample of the general population of Greece (N = 4894 participants). The period of data collection just preceded the emergence of the financial crisis in Greece.

RESULTS

The majority of the population did not report HAC, AUD or abstinence from alcohol. HAC was reported by 12.7% (95% CI: 11.8-13.6) of the population while 3.1% (95% CI: 2.7-3.6) met criteria for AUD. Younger age, divorce, lower educational level, living in an urban area, physical health problems, and smoking were associated with a higher prevalence of both conditions. Presence of severe financial difficulties and never married family status were associated with a higher prevalence of HAC but not AUD. HAC was associated with nonspecific psychiatric morbidity while AUD was associated with more specific psychiatric disorders. Conclusion/Importance. Both alcohol-related problems are frequent in the general population and have common and distinct determinants. The comparison between the findings of our study and those of similar studies during or after the period of financial austerity in Greece, would offer the opportunity to assess the possible effects of changes in the economical context in the determinants of alcohol-related problems.

The Victorian Intergenerational Health Cohort Study (VIHCS): Study design of a preconception cohort from parent adolescence to offspring childhood

BACKGROUND

There is increasing evidence that parental determinants of offspring early life development begin well before pregnancy.

OBJECTIVES

We established the Victorian Intergenerational Health Cohort Study (VIHCS) to examine the contributions of parental mental health, substance use, and socio-economic characteristics before pregnancy to child emotional, physical, social, and cognitive development.

POPULATION

Men and women were recruited from the Victorian Adolescent Health Cohort (VAHCS), an existing cohort study beginning in 1992 that assessed a representative sample of 1943 secondary school students in Victoria, Australia, repeatedly from adolescence (wave 1, mean age 14 years) to adulthood (wave 10, mean age 35 years).

METHODS

Victorian Adolescent Health Cohort participants with children born between 2006 and 2013 were recruited to VIHCS and invited to participate during trimester three, at 2 months postpartum, and 1 year postpartum. Parental mental health, substance use and socio-economic characteristics were assessed repeatedly throughout; infant characteristics were assessed postnatally and in infancy. Data will be supplemented by linkage to routine datasets. A further follow-up is underway as children reach 8 years of age.

PRELIMINARY RESULTS

Of the 1307 infants born to VAHCS participants between 2006 and 2013, 1030 were recruited to VIHCS. At VIHCS study entry, 18% of recruited parents had preconception common mental disorder in adolescence and young adulthood, 18% smoked daily in adolescence and young adulthood, and 6% had not completed high school. Half of VIHCS infants were female (48%), 4% were from multiple births, and 7% were preterm (<37 weeks' gestation).

CONCLUSIONS

Victorian Intergenerational Health Cohort Study is a prospective cohort of 1030 children with up to nine waves of preconception parental data and three waves of perinatal parental and infant data. These will allow examination of continuities of parental health and health risks from the decades before pregnancy to offspring childhood, and the contributions of exposures before pregnancy to offspring outcomes in childhood.

Pre-conception self-harm, maternal mental health and mother-infant bonding problems: a 20-year prospective cohort study

BACKGROUND

Self-harm in young people is associated with later problems in social and emotional development. However, it is unknown whether self-harm in young women continues to be a marker of vulnerability on becoming a parent. This study prospectively describes the associations between pre-conception self-harm, maternal depressive symptoms and mother-infant bonding problems.

METHODS

The Victorian Intergenerational Health Cohort Study (VIHCS) is a follow-up to the Victorian Adolescent Health Cohort Study (VAHCS) in Australia. Socio-demographic and health variables were assessed at 10 time-points (waves) from ages 14 to 35, including self-reported self-harm at waves 3-9. VIHCS enrolment began in 2006 (when participants were aged 28-29 years), by contacting VAHCS women every 6 months to identify pregnancies over a 7-year period. Perinatal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale during the third trimester, and 2 and 12 months postpartum. Mother-infant bonding problems were assessed with the Postpartum Bonding Questionnaire at 2 and 12 months postpartum.

RESULTS

Five hundred sixty-four pregnancies from 384 women were included. One in 10 women (9.7%) reported pre-conception self-harm. Women who reported self-harming in young adulthood (ages 20-29) reported higher levels of perinatal depressive symptoms and mother-infant bonding problems at all perinatal time points [perinatal depressive symptoms adjusted β = 5.40, 95% confidence interval (CI) 3.42-7.39; mother-infant bonding problems adjusted β = 7.51, 95% CI 3.09-11.92]. There was no evidence that self-harm in adolescence (ages 15-17) was associated with either perinatal outcome.

CONCLUSIONS

Self-harm during young adulthood may be an indicator of future vulnerability to perinatal mental health and mother-infant bonding problems.

Epidemiology of Alcohol Use in Late Adolescence in Greece and Comorbidity with Depression and Other Common Mental Disorders

BACKGROUND

The aim of the current study was to examine the prevalence and associations of hazardous alcohol use with sociodemographic variables and its comorbidity with depression and other common mental disorders in a sample of Greek adolescents between 16 and 18 year old.

METHODS

We recruited 2431 adolescents attending 25 senior high schools in Greece. We assessed depressive and anxiety disorders using the computerized version of a fully-structured psychiatric interview (the revised Clinical Interview Schedule / CIS-R). Alcohol use was assessed using questions taken from a previous WHO school survey.

RESULTS

Approximately one-third of adolescents (overall: 30.7%, boys: 39.2%, girls: 21.9%, p < 0.001) consumed alcohol on a weekly basis. The experience of excessive consumption, leading to drunkenness at least two or more times in their lifetime, was reported by 15.39% of the adolescents (19.42% for the boys and 11.24% for the girls, p < 0.001). Frequent alcohol consumption and drunkenness were strongly associated with the presence of depression, all other anxiety disorders except panic disorder, current smoking, and lifetime cannabis use, lower school performance, bad or fair relationship with parents, and increased health services use.

CONCLUSION

Alcohol use is highly prevalent among Greek adolescents. Special attention for the development of more focused preventive strategies should be paid to adolescents suffering from depression or other common mental disorders.

A comparison of the interviewer-administered phone and self-complete online versions of the computerized eMINI 6.0 in a sample of pregnant women

BACKGROUND

This study compares the prevalence rates of depressive and anxiety disorders identified during pregnancy using an interviewer-administered phone version and a self-complete online version of the computerized eMINI 6.0.

METHODS

888 pregnant women completed the computerized eMINI 6.0 (interviewer-administered phone, n = 253; self-complete online, n = 635).

RESULTS

There were no significant differences in the proportions of women meeting eMINI 6.0 criteria for current major depression, any current anxiety disorder, or lifetime panic or depressive disorder, by mode of administration. However, a greater proportion of women in the interviewer-administered phone group than in the self-complete online group met criteria for current minor depression (2.0% vs 0.2%, p = .008).

LIMITATIONS

Study limitations include its non-randomized design, overall low prevalence of depressive and anxiety disorders in the sample and inclusion of only a select number of eMINI 6.0 modules.

CONCLUSIONS

This study demonstrated few differences in the rates of DSM-IV depressive and anxiety disorders identified between the interviewer-administered and self-administered versions of the eMINI 6.0. Findings provide preliminary support the practical value of self-completed computerized interviews in large scale studies examining common mental disorders in pregnant women.

An evaluation of automated, internet-based psychiatric history taking

History taking using a web-based, automated software module (Historian) was compared with standard outpatient initial assessment on a community sample of 27 new psychiatric outpatients. The comprehensiveness and acceptability of the computer interview was evaluated. Historian was found to take psychiatric histories comparable with regard to content and comprehensiveness with those taken by clinicians. Historian was found to be highly acceptable to patients on a wide range of measures. History-taking software may help to prioritise referrals, focus the initial assessment and reduce consultation time in a psychiatric outpatient setting. The availability of a comprehensive history (Historian) is likely to lead to a shorter face-to-face consultation which could then be better focused on diagnosis and treatment. Service users with special needs such as hearing impairment, poor mobility or with no command of the English language (but literate in their native tongue) may benefit from improved access to psychiatric services.

Debt Counselling for Depression in Primary Care: an adaptive randomised controlled pilot trial (DeCoDer study)

BACKGROUND

Depression and debt are common in the UK. Debt Counselling for Depression in Primary Care: an adaptive randomised controlled pilot trial (DeCoDer) aimed to assess the clinical effectiveness and cost-effectiveness of the addition of a primary care debt counselling advice service to usual care for patients with depression and debt. However, the study was terminated early during the internal pilot trial phase because of recruitment delays. This report describes the rationale, methods and findings of the pilot study, and implications for future research.

OBJECTIVES

The overarching aim of the internal pilot was to identify and resolve problems, thereby assessing the feasibility of the main trial. The specific objectives were to confirm methods for practice recruitment and the ability to recruit patients via the proposed approaches; to determine the acceptability of the study interventions and outcome measures; to assess contamination; to confirm the randomisation method for main trial and the level of participant attrition; and to check the robustness of data collection systems.

DESIGN

An adaptive, parallel, two-group multicentre randomised controlled pilot trial with a nested mixed-methods process and economic evaluation. Both individual- and cluster (general practice)-level were was used in the pilot phase to assign participants to intervention or control groups.

SETTING

General practices in England and Wales.

PARTICIPANTS

Individuals were included who were aged ≥ 18 years, scored ≥ 14 on the Beck Depression Inventory II and self-identified as having debt worries. The main exclusion criteria were being actively suicidal or psychotic and/or severely depressed and unresponsive to treatment; having a severe addiction to alcohol/illicit drugs; being unable/unwilling to give written informed consent; currently participating in other research including follow-up phases; having received Citizens Advice Bureau (CAB) debt advice in the past year; and not wanting debt advice via a general practice.

INTERVENTIONS

The participants in the intervention group were given debt advice provided by the CAB and shared biopsychosocial assessment, in addition to treatment as usual (TAU) and two debt advice leaflets. The participants in the control group were given advice leaflets provided by the general practitioner and TAU only.

MAIN OUTCOME MEASURES

(1) Outcomes of the pilot trial - the proportion of eligible patients who consented, the number of participants recruited compared with target, assessment of contamination, and assessment of patient satisfaction with intervention and outcome measures. (2) Participant outcomes - primary - Beck Depression Inventory II; secondary - psychological well-being, health and social care utilisation, service satisfaction, substance misuse, record of priority/non-priority debts, life events and difficulties, and explanatory measures. Outcomes were assessed at baseline (pre-randomisation) and at 4 months post randomisation. Other data sources - qualitative interviews were conducted with participants, clinicians and CAB advisors.

RESULTS

Of the 238 expressions of interest screened, 61 participants (26%) were recruited and randomised (32 in the intervention group and 29 in the control group). All participants provided baseline outcomes and 52 provided the primary outcome at 4 months' follow-up (14.7% dropout). Seventeen participants allocated to the intervention saw a CAB advisor. Descriptive statistics are reported for participants with complete outcomes at baseline and 4 months' follow-up. Our qualitative findings suggest that the relationship between debt and depression is complex, and the impact of each on the other is compounded by other psychological, social and contextual influences.

CONCLUSIONS

As a result of low recruitment, this trial was terminated at the internal pilot phase and was too small for inferential statistical analysis. We recommend ways to reduce this risk when conducting complex trials among vulnerable populations recruited in community settings. These cover trial design, the design and delivery of interventions, recruitment strategies and support for sites.

Anxiety disorders, gender nonconformity, bullying and self-esteem in sexual minority adolescents: prospective birth cohort study

BACKGROUND

Sexual minority adolescents (i.e. youth not exclusively heterosexual) report more anxiety than heterosexual youth on symptom questionnaires but no research has used standardised diagnostic tools to investigate anxiety disorder risk. This study uses a UK birth cohort to investigate the risk of anxiety disorders in sexual minority and heterosexual youth using a computerised structured clinical interview and explores the influence of gender nonconformity, bullying and self-esteem.

METHODS

Participants were 4,564 adolescents (2,567 girls and 1,996 boys) from the Avon Longitudinal Study of Parents and Children (ALSPAC). Logistic regression analyses were performed to investigate the association between sexual orientation at 15.5 years and the presence of an anxiety disorder at 17.5 years. Covariates including maternal occupation, ethnicity, mother-reported childhood gender nonconformity at 30, 42 and 57 months, child-reported gender nonconformity at 8 years, child-reported bullying between 12 and 16 years and self-esteem at 17.5 years were added sequentially to regression models.

RESULTS

Sexual minority adolescents (i.e. those not exclusively heterosexual) had higher early childhood gender nonconformity (CGN), lower self-esteem and reported more bullying than adolescents identifying as 100% heterosexual. Minority sexual orientation at 15.5 years was associated with increased risk of an anxiety disorder at 17.5 years for girls (OR 2.55, CI 1.85-3.52) and boys (OR 2.48, CI 1.40-4.39). Adjusting for ethnicity, maternal occupation, mother-reported and child-reported CGN had minimal impact on this association. Adjusting for bullying between 12 and 16 years and self-esteem at 17.5 years reduced the strength of the associations, although the overall association remained significant for both sexes (girls OR 2.14 and boys OR 1.93).

CONCLUSIONS

Sexual minority youth are at increased risk of anxiety disorders relative to heterosexual youth at 17.5 years. Bullying between 12-16 years and lower self-esteem may contribute to this risk.

The level of cognitive function and recognition of emotions in older adults

Background

The association between cognitive decline and the ability to recognise emotions in interpersonal communication is not well understood. We aimed to investigate the association between cognitive function and the ability to recognise emotions in other people’s facial expressions across the full continuum of cognitive capacity.

Methods

Cross-sectional analysis of 4039 participants (3016 men, 1023 women aged 59 to 82 years) in the Whitehall II study. Cognitive function was assessed using a 30-item Mini-Mental State Examination (MMSE), further classified into 8 groups: 30, 29, 28, 27, 26, 25, 24, and <24 (possible dementia) MMSE points. The Facial Expression Recognition Task (FERT) was used to examine recognition of anger, fear, disgust, sadness, and happiness.

Results

The multivariable adjusted difference in the percentage of accurate recognition between the highest and lowest MMSE group was 14.9 (95%CI, 11.1–18.7) for anger, 15.5 (11.9–19.2) for fear, 18.5 (15.2–21.8) for disgust, 11.6 (7.3–16.0) for sadness, and 6.3 (3.1–9.4) for happiness. However, recognition of several emotions was reduced already after 1 to 2-point reduction in MMSE and with further points down in MMSE, the recognition worsened at an accelerated rate.

Conclusions

The ability to recognize emotion in facial expressions is affected at an early stage of cognitive impairment and might decline at an accelerated rate with the deterioration of cognitive function. Accurate recognition of happiness seems to be less affected by a severe decline in cognitive performance than recognition of negatively valued emotions.

Epidemiology and comorbidity of obsessive-compulsive disorder in late adolescence: a cross-sectional study in senior high schools in Greece

OBJECTIVE

The aim of this study was to examine the epidemiology, comorbidity and use of health services of obsessive-compulsive disorder (OCD) and subclinical obsessive-compulsive symptoms in late adolescence.

METHODS

A total of 2427 adolescents attending senior high schools in Greece were selected for a detailed psychiatric interview using the revised clinical interview schedule (CIS-R). Use of alcohol, nicotine and cannabis, and several socio-demographic and socio-economic variables were also assessed.

RESULTS

The prevalence of OCD was 1.39% (95% confidence interval [CI]: 1.05-1.84) while that of subclinical obsessive-compulsive symptoms was 2.77% (2.22-3.45). There was a female preponderance for subclinical symptoms. Financial difficulties of the family was the only socio-demographic variable that was significantly associated with OCD but not with subclinical symptoms. The pattern of comorbidity was similar for both conditions but milder in the subclinical form. About one in three reported use of general health services and one in ten use of psychiatric services.

CONCLUSIONS

OCD and subclinical obsessive-compulsive symptoms were relatively common. Comorbidity with other psychiatric disorders and use of substances was considerable even in subclinical status, but use of specialised health services was small. Clinical and research implications are discussed.

Sugar intake from sweet food and beverages, common mental disorder and depression: prospective findings from the Whitehall II study

Intake of sweet food, beverages and added sugars has been linked with depressive symptoms in several populations. Aim of this study was to investigate systematically cross-sectional and prospective associations between sweet food/beverage intake, common mental disorder (CMD) and depression and to examine the role of reverse causation (influence of mood on intake) as potential explanation for the observed linkage. We analysed repeated measures (23,245 person-observations) from the Whitehall II study using random effects regression. Diet was assessed using food frequency questionnaires, mood using validated questionnaires. Cross-sectional analyses showed positive associations. In prospective analyses, men in the highest tertile of sugar intake from sweet food/beverages had a 23% increased odds of incident CMD after 5 years (95% CI: 1.02, 1.48) independent of health behaviours, socio-demographic and diet-related factors, adiposity and other diseases. The odds of recurrent depression were increased in the highest tertile for both sexes, but not statistically significant when diet-related factors were included in the model (OR 1.47; 95% CI: 0.98, 2.22). Neither CMD nor depression predicted intake changes. Our research confirms an adverse effect of sugar intake from sweet food/beverage on long-term psychological health and suggests that lower intake of sugar may be associated with better psychological health.

20-year outcomes in adolescents who self-harm: a population-based cohort study

BACKGROUND

Little is known about the long-term psychosocial outcomes associated with self-harm during adolescence. We aimed to determine whether adolescents who self-harm are at increased risk of adverse psychosocial outcomes in the fourth decade of life, using data from the Victorian Adolescent Health Cohort Study.

METHODS

We recruited a stratified, random sample of 1943 adolescents from 44 schools across the state of Victoria, Australia. The study started on Aug 20, 1992, and finished on March 4, 2014. We obtained data relating to self-harm from questionnaires and telephone interviews at eight waves of follow-up, commencing at mean age 15·9 years (SD 0·5; waves 3-6 during adolescence, 6 months apart) and ending at mean age 35·1 years (SD 0·6; wave 10). The outcome measures at age 35 years were social disadvantage (divorced or separated, not in a relationship, not earning money, receipt of government welfare, and experiencing financial hardship), common mental disorders such as depression and anxiety, and substance use. We assessed the associations between self-harm during adolescence and the outcome measures at 35 years (wave 10) using logistic regression models, with progressive adjustment: (1) adjustment for sex and age; (2) further adjustment for background social factors; (3) additional adjustment for common mental disorder in adolescence; and (4) final additional adjustment for adolescent antisocial behaviour and substance use measures.

FINDINGS

From the total cohort of 1943 participants, 1802 participants were assessed for self-harm during adolescence (between waves 3 and 6). Of these, 1671 were included in the analysis sample. 135 (8%) reported having self-harmed at least once during adolescence. At 35 years (wave 10), mental health problems, daily tobacco smoking, illicit drug use, and dependence were all more common in participants who had reported self-harm during the adolescent phase of the study (n=135) than in those who had not (n=1536): for social disadvantage odds ratios [ORs] ranged from 1·34 (95% CI 1·25-1·43) for unemployment to 1·88 (1·78-1·98) for financial hardship; for mental health they ranged from 1·61 (1·51-1·72) for depression to 1·92 (1·79-2·04) for anxiety; for illicit drug use they ranged from 1·36 (1·25-1·49) for any amphetamine use to 3·39 (3·12-3·67) for weekly cannabis use; for dependence syndrome they were 1·72 (1·57-1·87) for nicotine dependence, 2·67 (2·38-2·99) for cannabis dependence, and 1·74 (1·62-1·86) for any dependence; and the OR for daily smoking was 2·00 (1·89-2·12). Adjustment for socio-demographic factors made little difference to these associations but a further adjustment for adolescent common mental disorders substantially attenuated most associations, with the exception of daily tobacco smoking (adjusted OR 1·74, 95% CI 1·08-2·81), any illicit drug use (1·72, 1·07-2·79) and weekly cannabis use (3·18, 1·58-6·42). Further adjustment for adolescent risky substance use and antisocial behaviour attenuated the remaining associations, with the exception of weekly cannabis use at age 35 years, which remained independently associated with self-harm during adolescence (2·27, 1·09-4·69).

INTERPRETATION

Adolescents who self-harm are more likely to experience a wide range of psychosocial problems later in life. With the notable exception of heavy cannabis use, these problems appear to be largely accounted for by concurrent adolescent mental health disorders and substance use. Complex interventions addressing the domains of mental state, behaviour, and substance use are likely to be most successful in helping this susceptible group adjust to adult life.

Drinking patterns of adolescents who develop alcohol use disorders: results from the Victorian Adolescent Health Cohort Study

OBJECTIVE

We identify drinking styles that place teens at greatest risk of later alcohol use disorders (AUD).

DESIGN

Population-based cohort study.

SETTING

Victoria, Australia.

PARTICIPANTS

A representative sample of 1943 adolescents living in Victoria in 1992.

OUTCOME MEASURES

Teen drinking was assessed at 6 monthly intervals (5 waves) between mean ages 14.9 and 17.4 years and summarised across waves as none, one, or two or more waves of: (1) frequent drinking (3+ days in the past week), (2) loss of control over drinking (difficulty stopping, amnesia), (3) binge drinking (5+ standard drinks in a day) and (4) heavy binge drinking (20+ and 11+ standard drinks in a day for males and females, respectively). Young Adult Alcohol Use Disorder (AUD) was assessed at 3 yearly intervals (3 waves) across the 20s (mean ages 20.7 through 29.1 years).

RESULTS

We show that patterns of teen drinking characterised by loss of control increase risk for AUD across young adulthood: loss of control over drinking (one wave OR 1.4, 95% CI 1.1 to 1.8; two or more waves OR 1.9, CI 1.4 to 2.7); binge drinking (one wave OR 1.7, CI 1.3 to 2.3; two or more waves OR 2.0, CI 1.5 to 2.6), and heavy binge drinking (one wave OR 2.0, CI 1.4 to 2.8; two or more waves OR 2.3, CI 1.6 to 3.4). This is not so for frequent drinking, which was unrelated to later AUD. Although drinking was more common in males, there was no evidence of sex differences in risk relationships.

CONCLUSIONS

Our results extend previous work by showing that patterns of drinking that represent loss of control over alcohol consumption (however expressed) are important targets for intervention. In addition to current policies that may reduce overall consumption, emphasising prevention of more extreme teenage bouts of alcohol consumption appears warranted.

Depression in late adolescence: a cross-sectional study in senior high schools in Greece

BACKGROUND

Depression is a common mental health problem in adolescents worldwide. The aim of the present study was to investigate the prevalence, comorbidity and sociodemographic and socioeconomic associations of depression and depressive symptoms, as well as the relevant health services use in a sample of adolescents in Greece.

METHODS

Five thousand six hundred fourteen adolescents aged 16-18 years old and attending 25 senior high schools were screened and a stratified random sample of 2,427 were selected for a detailed interview. Psychiatric morbidity was assessed with a fully structured psychiatric interview, the revised Clinical Interview Schedule (CIS-R). The use of substances, such as alcohol, nicotine and cannabis, and several sociodemographic and socioeconomic variables have been also assessed.

RESULTS

In our sample the prevalence rates were 5.67 % for the depressive episode according to ICD-10 and 17.43 % for a broader definition of depressive symptoms. 49.38 % of the adolescents with depressive episode had at least one comorbid anxiety disorder [OR: 7.76 (5.52-10.92)]. Only 17.08 % of the adolescents with depression have visited a doctor due to a psychological problem during the previous year. Anxiety disorders, substance use, female gender, older age, having one sibling, and divorce or separation of the parents were all associated with depression. In addition, the presence of financial difficulties in the family was significantly associated with an increased prevalence of both depression and depressive symptoms.

CONCLUSIONS

Prevalence and comorbidity rates of depression among Greek adolescents are substantial. Only a small minority of depressed adolescents seek professional help. Significant associations with financial difficulties are reported.

Replication of a whole school ethos-changing intervention: different context, similar effects, additional insights

BACKGROUND

Whole school, ethos-changing interventions reduce risk behaviours in middle adolescence, more than curriculum-based approaches. Effects on older ages are not known. We set out to replicate one of these interventions, Australia's Gatehouse Project, in a rural Canadian high school.

METHODS

A guided, whole school change process sought to make students feel more safe, connected, and valued by: changes in teaching practices, orientation processes, professional development of staff, recognition and reward mechanisms, elevating student voice, and strategies to involve greater proactivity and participation. We conducted risk behaviour surveys in grades 10 to 12 before the intervention and 2 years afterwards, and social network analyses with the staff. Changes in health and health risk behaviours were assessed using chi-square. Interactions between the intervention and gender and between the intervention and school engagement were assessed using interaction terms in logistic regression models. Changes in the density of relationships among staff were tested with methods analogous to paired t-tests.

RESULTS

Like Gatehouse, there was no statistically significant reduction in depressive symptoms or bullying, though the trend was in that direction. Among girls, there was a statistically significant decrease in low school engagement (45% relative reduction), and decreases in drinking (46% relative reduction), unprotected sex (61% relative reduction) and poor health (relative reduction of 73%). The reduction in drinking matched the national trend. Reductions in unprotected sex and poor health went against the national trend. We found no statistically significant changes for boys. The effects coincided with statistically significant increases in the densities of staff networks, indicating that part of the mechanism may be through relationships at school.

CONCLUSIONS

A non-specific, risk protective intervention in the social environment of the school had a significant impact on a cluster of risk behaviours for girls. Results were remarkably like reports from similar school environment interventions elsewhere, albeit with different behaviours being affected. It may be that this type of intervention activates change processes that interact highly with context, impacting different risks differently, according to the prevalence, salience and distribution of the risk and the interconnectivity of relationships between staff and students. This requires further exploration.

Cognitive styles and future depressed mood in early adulthood: the importance of global attributions

BACKGROUND

Cognitive theories of depression suggest that beliefs of low self-worth and the tendency to attribute negative events to causes that are global (widespread rather than specific) and stable (will persist rather than change in the future) are associated with the development of depressed mood. Such theories are supported by evidence from prospective studies and have guided the development of successful treatment and prevention strategies such as CBT. However, the relative importance of different psychological constructs within cognitive theories is unknown. This is important to refine cognitive theories and develop more efficient prevention strategies.

METHOD

We used prospective data from over 3500 young adults from the Avon Longitudinal Study for Parents and Children (ALSPAC) cohort in the UK to investigate the association between cognitive style, measured by short forms of the Dysfunctional Attitudes Scale (DAS) and Cognitive Styles Questionnaire-Short Form (CSQ-SF) at age 18, and future depressed mood at age 19. Structural equation modelling techniques were used to separate cognitive style constructs.

RESULTS

Cognitive styles were associated with future depressed mood, independently of baseline mood, both as measured by the DAS-SF and the CSQ-SF. Of the different CSQ-SF constructs, only global attributions were associated with both baseline and future mood independently of other constructs.

LIMITATIONS

The study was subject to attrition and the follow-up was relatively short (10 months).

CONCLUSION

The findings suggest that the tendency to attribute negative events specifically to global causes could be particularly important for depression. Reducing global attributions is potentially important in the prevention and treatment of depression.

Association of the catechol-O-methyltransferase val158met polymorphism and anxiety-related traits: a meta-analysis

OBJECTIVES

The aims of this study were (i) to examine genotypic association of the catechol-O-methyltransferase (COMT) val158met polymorphism with anxiety-related traits with a meta-analysis; (ii) to examine sex and ethnicity as moderators of the association; and (iii) to evaluate whether the association differed by particular anxiety traits.

METHODS

Association studies of the COMT val158met polymorphism and anxiety traits were identified from the PubMed or PsycInfo databases, conference abstracts, and listserv postings. Exclusion criteria were (a) pediatric samples, (b) exclusively clinical samples, and (c) samples selected for a nonanxiety phenotype. Standardized mean differences in anxiety between genotypes were aggregated to produce mean effect sizes across all available samples, and for subgroups stratified by sex and ethnicity (Whites vs. Asians). Construct-specific analysis was conducted to evaluate the association of COMT with neuroticism, harm avoidance, and behavioral inhibition.

RESULTS

Twenty-seven eligible studies (N=15 979) with available data were identified. Overall findings indicate sex-specific and ethnic-specific effects: valine homozygotes had higher neuroticism than methionine homozygotes in studies of White males [mean effect size(Equation is included in full-text article.)=0.13; 95% CI 0.02, 0.25; P=0.03], and higher harm avoidance in studies of Asian males ((Equation is included in full-text article.)=0.43; 95% CI 0.14, 0.72; P=0.004). No significant associations were found in women and effect sizes were diminished when studies were aggregated across ethnicity or anxiety traits.

CONCLUSION

This meta-analysis provides evidence for sex and ethnic differences in the association of the COMT val158met polymorphism with anxiety traits. Our findings contribute to current knowledge on the relation between prefrontal dopaminergic transmission and anxiety.

The association between bullying-related behaviours and subjective health complaints in late adolescence: cross-sectional study in Greece

BACKGROUND

Bullying is quite prevalent in the school setting and has been associated with several subjective health complaints such as headache, backache, abdominal pain, dizziness, fatigue and sleep problems. The aim of the present study was to investigate the association between bullying and subjective health complaints in a sample of Greek adolescents taking into account the presence of psychiatric morbidity.

METHODS

A stratified random sample of 2427 adolescents aged 16-18 years old and attending senior high schools were randomly selected for a computerized interview. Subjective health complaints were assessed using a symptom checklist used in the context of a previous World Health Organization study and relevant sections of the revised Clinical Interview Schedule (CIS-R). The latter was also used for the assessment of psychiatric morbidity. Bullying was assessed with the revised Olweus bully/victim questionnaire. A series of logistic regression models were used to investigate the association between bullying and subjective health complaints.

RESULTS

Victims of bullying were more likely to report backache (Odds Ratio [OR] = 1.92, 95% CI: 1.01-3.67), dizziness (OR = 2.83, 95% CI: 1.11-7.22) and fatigue (OR = 0.41, 95% CI: 0.19-0.86), independently of the presence of psychiatric morbidity. In addition bullying perpetrators were more likely to report backache (OR = 3.49, 95% CI: 1.49-8.18). It is worth noting that sleep problems and abdominal pain were also associated with being bullied and fatigue with bullying perpetration but these associations were all attenuated after adjustment for psychiatric morbidity.

CONCLUSIONS

Strong associations between bullying in schools and subjective health complaints among a sample of Greek students aged 16-18 years have been observed. The exact nature of these associations should be investigated in future longitudinal studies.

Use of self-administered instruments to assess psychiatric disorders in older people: validity of the General Health Questionnaire, the Center for Epidemiologic Studies Depression Scale and the self-completion version of the revised Clinical Interview Schedule

BACKGROUND

Diagnosis of depressive disorder using interviewer-administered instruments is expensive and frequently impractical in large epidemiological surveys. The aim of this study was to assess the validity of three self-completion measures of depressive disorder and other psychiatric disorders in older people against an interviewer-administered instrument.

METHOD

A random sample stratified by sex, age and social position was selected from the Whitehall II study participants. This sample was supplemented by inclusion of depressed Whitehall II participants. Depressive disorder and other mental disorders were assessed by the interviewer-administered structured revised Clinical Interview Schedule (CIS-R) in 277 participants aged 58-80 years. Participants also completed a computerized self-completion version of the CIS-R in addition to the General Health Questionnaire (GHQ) and the Center for Epidemiologic Studies Depression Scale (CES-D).

RESULTS

The mean total score was similar for the interviewer-administered (4.43) and self-completion (4.35) versions of the CIS-R [95% confidence interval (CI) for difference -0.31 to 0.16]. Differences were not related to sex, age, social position or presence of chronic physical illness. Sensitivity/specificity of self-completion CIS-R was 74%/98% for any mental disorder and 75%/98% for depressive episode. The corresponding figures were 86%/87% and 78%/83% for GHQ and 77%/89% and 89%/86% for CES-D.

CONCLUSIONS

The self-completion computerized version of the CIS-R is feasible and has good validity as a measure of any mental disorder and depression in people aged ≥ 60 years. GHQ and CES-D also have good criterion validity as measures of any mental disorder and depressive disorder respectively.

Prevalence and sociodemographic associations of common mental disorders in a nationally representative sample of the general population of Greece

BACKGROUND

No study in Greece has assessed so far the full range of common mental disorders using a representative sample of the population from both mainland and insular regions of the country. The aim of the present paper was to present the results of the first such study.

METHODS

The study was carried out between 2009-2010 in a nationally representative sample of 4894 individuals living in private households in Greece. Common mental disorders in the past week were assessed with the revised Clinical Interview Schedule (CIS-R). We also assessed alcohol use disorders (using AUDIT), smoking and cannabis use.

RESULTS

14% of the population (Male: 11%, Female: 17%) was found to have clinically significant psychiatric morbidity according to the scores on the CIS-R. The prevalence (past seven days) of specific common mental disorders was as follows: Generalized Anxiety Disorder: 4.10% (95% CI: 3.54, 4.65); Depression: 2.90% (2.43, 3.37); Panic Disorder: 1.88% (1.50, 2.26); Obsessive-Compulsive Disorder: 1.69% (1.33, 2.05); All Phobias: 2.79% (2.33, 3.26); Mixed anxiety-depression: 2.67% (2.22, 3.12). Harmful alcohol use was reported by 12.69% of the population (11.75, 13.62). Regular smoking was reported by 39.60% of the population (38.22, 40.97) while cannabis use (at least once during the past month) by 2.06% (1.66, 2.46). Clinically significant psychiatric morbidity was positively associated with the following variables: female gender, divorced or widowed family status, low educational status and unemployment. Use of all substances was more common in men compared to women. Common mental disorders were often comorbid, undertreated, and associated with a lower quality of life.

CONCLUSIONS

The findings of the present study can help in the better planning and development of mental health services in Greece, especially in a time of mental health budget restrictions.

The persistence of the association between adolescent cannabis use and common mental disorders into young adulthood

AIMS

Debate continues about whether the association between cannabis use in adolescence and common mental disorders is causal. Most reports have focused on associations in adolescence, with few studies extending into adulthood. We examine the association from adolescence until the age of 29 years in a representative prospective cohort of young Australians.

DESIGN

Nine-wave, 15-year representative longitudinal cohort study, with six waves of data collection in adolescence (mean age 14.9-17.4 years) and three in young adulthood (mean age 20.7, 24.1 and 29.1 years).

PARTICIPANTS

Participants were a cohort of 1943 recruited in secondary school and surveyed at each wave when possible from mid-teen age to their late 20s.

SETTING

Victoria, Australia.

MEASUREMENTS

Psychiatric morbidity was assessed with the Revised Clinical Interview Schedule (CIS-R) at each adolescent wave, and as Composite International Diagnostic Interview (CIDI)-defined ICD-10 major depressive episode and anxiety disorder at 29 years. Frequency of cannabis use was measured in the past 6 months in adolescence. Cannabis use frequency in the last year and DSM-IV cannabis dependence were assessed at 29 years. Cross-sectional and prospective associations of these outcomes with cannabis use and dependence were estimated as odds ratios (OR), using multivariable logistic regression models, with the outcomes of interest, major depressive episode (MDE) and anxiety disorder (AD) at 29 years.

FINDINGS

There were no consistent associations between adolescent cannabis use and depression at age 29 years. Daily cannabis use was associated with anxiety disorder at 29 years [adjusted OR 2.5, 95% confidence interval (CI):< 1.2-5.2], as was cannabis dependence (adjusted OR 2.2, 95% CI: 1.1-4.4). Among weekly+ adolescent cannabis users, those who continued to use cannabis use daily at 29 years remained at significantly increased odds of anxiety disorder (adjusted OR 3.2, 95% CI: 1.1-9.2).

CONCLUSIONS

Regular (particularly daily) adolescent cannabis use is associated consistently with anxiety, but not depressive disorder, in adolescence and late young adulthood, even among regular users who then cease using the drug. It is possible that early cannabis exposure causes enduring mental health risks in the general cannabis-using adolescent population.

Cannabis and depression: an integrative data analysis of four Australasian cohorts

BACKGROUND

This study presents an integrative data analysis of the association between frequency of cannabis use and severity of depressive symptoms using data from four Australasian cohort studies. The integrated data comprised observations on over 6900 individuals studied on up to seven occasions between adolescence and mature adulthood.

METHODS

Repeated measures data on frequency of cannabis use (not used/<monthly/≥monthly/≥weekly) and concurrently assessed depression scores were pooled over the four cohorts. Regression models were fitted to estimate the strength of association between cannabis use and depression. Fixed effects regression methods were used to control for confounding by non-observed fixed factors.

RESULTS

Increasing frequency of cannabis use was associated with increasing depressive symptoms (p<0.001). In the pooled data weekly users of cannabis had depression scores that were 0.32 (95%CI 0.27-0.37) SD higher than non-users. The association was reduced but remained significant (p<0.001) upon adjustment for confounding. After adjustment depression scores for weekly users were 0.24 (95%CI 0.18-0.30) SD higher than non-users. The adjusted associations were similar across cohorts. There was a weak age×cannabis use interaction (p<0.05) suggesting that the association was strongest in adolescence. Attempts to further test the direction of causality using SEM methods proved equivocal.

CONCLUSIONS

More frequent cannabis use was associated with modest increases in rates of depressive symptoms. This association was stronger in adolescence and declined thereafter. However, it was not possible from the available data to draw a definitive conclusion as to the likely direction of causality between cannabis use and depression.

Economic evaluation of a task-shifting intervention for common mental disorders in India

OBJECTIVE

To carry out an economic evaluation of a task-shifting intervention for the treatment of depressive and anxiety disorders in primary-care settings in Goa, India.

METHODS

Cost-utility and cost-effectiveness analyses based on generalized linear models were performed within a trial set in 24 public and private primary-care facilities. Subjects were randomly assigned to an intervention or a control arm. Eligible subjects in the intervention arm were given psycho-education, case management, interpersonal psychotherapy and/or antidepressants by lay health workers. Subjects in the control arm were treated by physicians. The use of health-care resources, the disability of each subject and degree of psychiatric morbidity, as measured by the Revised Clinical Interview Schedule, were determined at 2, 6 and 12 months.

FINDINGS

Complete data, from all three follow-ups, were collected from 1243 (75.4%) and 938 (81.7%) of the subjects enrolled in the study facilities from the public and private sectors, respectively. Within the public facilities, subjects in the intervention arm showed greater improvement in all the health outcomes investigated than those in the control arm. Time costs were also significantly lower in the intervention arm than in the control arm, whereas health system costs in the two arms were similar. Within the private facilities, however, the effectiveness and costs recorded in the two arms were similar.

CONCLUSION

Within public primary-care facilities in Goa, the use of lay health workers in the care of subjects with common mental disorders was not only cost-effective but also cost-saving.

Bullying behaviour in schools, socioeconomic position and psychiatric morbidity: a cross-sectional study in late adolescents in Greece

BACKGROUND

Bullying is quite prevalent in the school setting and has been associated with the socioeconomic position and psychiatric morbidity of the pupils. The aim of the study was to investigate the association between bullying and socioeconomic status in a sample of Greek adolescents and to examine whether this is confounded by the presence of psychiatric morbidity, including sub-threshold forms of illness.

METHODS

5,614 adolescents aged 16-18 years old and attending 25 senior high schools were screened and a stratified random sample of 2,427 were selected for a detailed interview. Psychiatric morbidity was assessed with a fully structured psychiatric interview, the revised Clinical Interview Schedule (CIS-R), while bullying was assessed with the revised Olweus bully/victim questionnaire. The following socio-economic variables were assessed: parental educational level and employment status, financial difficulties of the family and adolescents' school performance. The associations were investigated using multinomial logit models.

RESULTS

26.4% of the pupils were involved in bullying-related behaviours at least once monthly either as victims, perpetrators or both, while more frequent involvement (at least once weekly) was reported by 4.1%. Psychiatric morbidity was associated with all types of bullying-related behaviours. No socioeconomic associations were reported for victimization. A lower school performance and unemployment of the father were significantly more likely among perpetrators, while economic inactivity of the mother was more likely in pupils who were both victims and perpetrators. These results were largely confirmed when we focused on high frequency behaviours only. In addition, being overweight increased the risk of frequent victimization.

CONCLUSIONS

The prevalence of bullying among Greek pupils is substantial. Perpetration was associated with some dimensions of adolescents' socioeconomic status, while victimization showed no socioeconomic associations. Our findings may add to the understanding of possible risk factors for bullying behaviours in adolescence.

Adolescent depressive symptoms and subsequent pregnancy, pregnancy completion and pregnancy termination in young adulthood: findings from the victorian adolescent health cohort study

STUDY OBJECTIVE

To examine relationships between depressive symptoms in adolescence (14-18 years of age) and becoming pregnant, completing a pregnancy (live birth) and terminating a pregnancy in young adulthood (21-24 years of age).

PARTICIPANTS AND DESIGN

Data from 1000 females were drawn from a larger sample of 1943 young Australians participating in a longitudinal study of adolescent health and development, followed across 8 waves from adolescence (waves 1-6) to young adulthood (waves 7 and 8).

SETTING

Victoria, Australia.

MAIN OUTCOME MEASURES

Pregnancy, pregnancy completion and pregnancy termination between 21-24 years of age.

RESULTS

We observed a twofold increase in the odds of becoming pregnant in those reporting persisting patterns of depressive symptoms during adolescence (2+ waves); however, after staged adjustment for adolescent antisocial behaviour, drug use and socioeconomic disadvantage, there was no evidence of association. Of particular note, and consistent with previous research, adolescent antisocial and drug use behavior were strongly associated with becoming pregnant and pregnancy termination in young adulthood.

CONCLUSIONS

Adolescent antisocial and drug use behavior, not depressive symptoms, independently predict pregnancy outcomes in young adulthood.

Mixed anxiety and depressive disorder outcomes: prospective cohort study in primary care

BACKGROUND

Mixed anxiety and depressive disorder (MADD) is common yet ill-defined, with little known about outcomes.

AIMS

To determine MADD outcomes over 1 year.

METHOD

We recruited 250 adults attending seven London general practices with mild-moderate distress. Three groups were defined using a diagnostic interview: MADD, other ICD-10 psychiatric diagnosis, no psychiatric diagnosis. We assessed symptoms of distress (General Health Questionnaire-28), quality of life (12-item Short Form Health Survey), general practitioner (GP) diagnosis and consultation rate at baseline, 3 months and 1 year.

RESULTS

Two-thirds of participants with MADD had no significant psychological distress at 3 months (61%) or 1 year (69%). However, compared with those with no diagnosis, individuals had twice the risk of significant distress (incidence rate ratio 2.39, 95% CI 1.29-4.42) at 3 months but not 1 year, and persistently lower quality of life (mental health functioning). There was no significant difference in GP consultation rate/diagnosis.

CONCLUSIONS

The majority with MADD improved, but individuals had an increased risk of significant distress at 3 months and a lower quality of life. As we cannot currently predict those with a poorer prognosis these patients should be actively monitored in primary care.

An empirical investigation of the structure of anxiety and depressive symptoms in late adolescence: cross-sectional study using the Greek version of the revised Clinical Interview Schedule

Several studies in the past have examined whether the hierarchical structure of anxiety and depressive symptoms can explain the high comorbidity between them but more studies are needed from other settings and with different methods. The present study aimed to examine the structure of common anxiety and depressive symptoms in adolescents 16-18 years old attending secondary schools using the Greek version of the revised Clinical Interview Schedule (CIS-R), a fully structured psychiatric interview. A total of 2431 adolescents were interviewed with the computerized version of the CIS-R. The hierarchical structure of 12 depressive and anxiety symptoms was examined with confirmatory factor analytical methods. Four alternative models of increasing complexity were tested. The best-fitting model included three first-order factors, representing the dimensions of anxiety, depression and non-specific distress respectively. A model with a higher-order factor representing the broader internalizing dimension was less supported by the data. The findings of this and other studies should be taken into account in future classifications of psychiatric disorders and may have clinical practical implications.

The association between bullying and early stages of suicidal ideation in late adolescents in Greece

BACKGROUND

Bullying in schools has been associated with suicidal ideation but the confounding effect of psychiatric morbidity has not always been taken into account. Our main aim was to test the association between bullying behavior and early stages of suicidal ideation in a sample of Greek adolescents and to examine whether this is independent of the presence of psychiatric morbidity, including sub-threshold symptoms.

METHODS

5614 pupils 16-18 years old and attending 25 senior high schools were screened in the first phase and a stratified random sample of 2431 were selected for a detailed interview at the second phase. Psychiatric morbidity and suicidal ideation were assessed with the revised Clinical Interview Schedule (CIS-R) while bullying was assessed with the revised Olweus bully/victim questionnaire.

RESULTS

Victims of bullying behavior were more likely to express suicidal ideation. This association was particularly strong for those who were bullied on a weekly basis and it was independent of the presence of psychiatric morbidity (Odds Ratio: 7.78; 95% Confidence Interval: 3.05 - 19.90). In contrast, being a perpetrator ("bullying others") was not associated with this type of ideation after adjustment. These findings were similar in both boys and girls, although the population impact of victimization in the prevalence of suicidal ideation was potentially higher for boys.

CONCLUSIONS

The strong cross-sectional association between frequent victimization and suicidal ideation in late adolescence offers an opportunity for identifying pupils in the school setting that are in a higher risk for exhibiting suicidal ideation.

A critical review of the empirical literature on the relation between anxiety and puberty

The current paper critically reviews the empirical literature focused on the association between puberty and anxiety. A detailed review of more than 45 empirical articles is provided. There is some evidence that among girls, but not boys, a more advanced pubertal status (controlling for age) is associated with higher reported anxiety symptoms. Also among girls, earlier pubertal timing is linked to higher anxiety scores. It is unclear whether early puberty may lead to increased anxiety or if high anxiety influences pubertal timing. With respect to hormones, there were relatively few significant associations for girls, although this literature is very small. Among boys, several studies reported positive associations between both gonadal and adrenal hormones and anxiety. The direction of effect for these finding is also unstudied. The primary limitation of the hormone-anxiety literature pertains to the absence of pubertal measures in samples of youth in which hormones are measured. The paper concludes with a comprehensive examination of the methodological strengths and weaknesses of the literature and recommendations for future work.

Poor social comparison and the tendency to submissive behavior in anorexia nervosa

OBJECTIVE

The aim of this study was to confirm an association between low social rank (SR) and anorexia nervosa (AN), and to test the hypotheses that low SR is (a) present after recovery from the illness, (b) mediates an association between increased childhood interpersonal adversity (CIA) and AN.

METHOD

Participants were 18 women with active AN, 13 recovered women, and 16 healthy controls. General and specific psychopathology, childhood adversity, and indices of SR were assessed using self-report measures.

RESULTS

Low SR was observed in both the active and the recovered AN groups and was a significant mediator in the relationship between CIA and AN status.

CONCLUSION

CIA may contribute to the risk of developing AN via its impact on the development of low SR. The latter may be a shared risk factor for AN and affective disorder, and could be a useful therapeutic target.

COMT Val158Met and 5HTTLPR functional loci interact to predict persistence of anxiety across adolescence: results from the Victorian Adolescent Health Cohort Study

We investigated whether a composite genetic factor, based on the combined actions of catechol-O-methyltransferase (COMT) (Val(158)Met) and serotonin transporter (5HTTLPR) (Long-Short) functional loci, has a greater capacity to predict persistence of anxiety across adolescence than either locus in isolation. Analyses were performed on DNA collected from 962 young Australians participating in an eight-wave longitudinal study of mental health and well-being (Victorian Adolescent Health Cohort Study). When the effects of each locus were examined separately, small dose-response reductions in the odds of reporting persisting generalized (free-floating) anxiety across adolescence were observed for the COMT Met(158) [odds ratio (OR) = 0.85, 95% confidence interval (CI) = 0.76-0.95, P = 0.004] and 5HTTLPR Short alleles (OR = 0.88, CI = 0.79-0.99, P = 0.033). There was no evidence for a dose-response interaction effect between loci. However, there was a double-recessive interaction effect in which the odds of reporting persisting generalized anxiety were more than twofold reduced (OR = 0.45, CI = 0.29-0.70, P < 0.001) among carriers homozygous for both the COMT Met(158) and the 5HTTLPR Short alleles (Met(158)Met + Short-Short) compared with the remaining cohort. The double-recessive effect remained after multivariate adjustment for a range of psychosocial predictors of anxiety. Exploratory stratified analyses suggested that genetic protection may be more pronounced under conditions of high stress (insecure attachments and sexual abuse), although strata differences did not reach statistical significance. By describing the interaction between genetic loci, it may be possible to describe composite genetic factors that have a more substantial impact on psychosocial development than individual loci alone, and in doing so, enhance understanding of the contribution of constitutional processes in mental health outcomes.

Social and school connectedness in early secondary school as predictors of late teenage substance use, mental health, and academic outcomes

PURPOSE

To examine associations between social relationships and school engagement in early secondary school and mental health, substance use, and educational achievement 2-4 years later.

METHODS

School-based longitudinal study of secondary school students, surveyed at school in Year 8 (13-14-years-old) and Year 10 (16-years-old), and 1-year post-secondary school. A total of 2678 Year 8 students (74%) participated in the first wave of data collection. For the school-based surveys, attrition was <10%. Seventy-one percent of the participating Year 8 students completed the post-secondary school survey.

RESULTS

Having both good school and social connectedness in Year 8 was associated with the best outcomes in later years. In contrast, participants with low school connectedness but good social connectedness were at elevated risk of anxiety/depressive symptoms (odds ratio [OR]: 1.3; 95% confidence interval [CI]: 1.0, 1.76), regular smoking (OR: 2.0; 95% CI: 1.4, 2.9), drinking (OR: 1.7; 95% CI: 1.3, 2.2), and using marijuana (OR: 2.0; 95% CI: 1.6, 2.5) in later years. The likelihood of completing school was reduced for those with either poor social connectedness, low school connectedness, or both.

CONCLUSIONS

Overall, young people's experiences of early secondary school and their relationships with others may continue to affect their moods, their substance use in later years, and their likelihood of completing secondary school. Having both good school connectedness and good social connectedness is associated with the best outcomes. The challenge is how to promote both school and social connectedness to best achieve these health and learning outcomes.

A randomized controlled trial of the effect of real-time telemedicine support on glycemic control in young adults with type 1 diabetes (ISRCTN 46889446)

OBJECTIVE

To determine whether a system of telemedicine support can improve glycemic control in type 1 diabetes.

RESEARCH DESIGN AND METHODS

A 9-month randomized trial compared glucose self-monitoring real-time result transmission and feedback of results for the previous 24 h in the control group with real-time graphical phone-based feedback for the previous 2 weeks together with nurse-initiated support using a web-based graphical analysis of glucose self-monitoring results in the intervention group. All patients aged 18-30 years with HbA(1c) (A1C) levels of 8-11% were eligible for inclusion.

RESULTS

A total of 93 patients (55 men) with mean diabetes duration (means +/- SD) 12.1 +/- 6.7 years were recruited from a young adult clinic. In total, the intervention and control groups transmitted 29,765 and 21,400 results, respectively. The corresponding median blood glucose levels were 8.9 mmol/l (interquartile range 5.4-13.5) and 10.3 mmol/l (6.5-14.4) (P < 0.0001). There was a reduction in A1C in the intervention group after 9 months from 9.2 +/- 1.1 to 8.6 +/- 1.4% (difference 0.6% [95% CI 0.3-1.0]) and a reduction in A1C in the control group from 9.3 +/- 1.5 to 8.9 +/- 1.4% (difference 0.4% [0.03-0.7]). This difference in change in A1C between groups was not statistically significant (0.2% [-0.2 to 0.7, P = 0.3).

CONCLUSIONS

Real-time telemedicine transmission and feedback of information about blood glucose results with nurse support is feasible and acceptable to patients, but to significantly improve glycemic control, access to real-time decision support for medication dosing and changes in diet and exercise may be required.

Association between 5-HTTLPR genotypes and persisting patterns of anxiety and alcohol use: results from a 10-year longitudinal study of adolescent mental health

The serotonin transporter gene (5-HTT) encodes a transmembrane protein that plays an important role in regulating serotonergic neurotransmission and related aspects of mood and behaviour. The short allele of a 44 bp insertion/deletion polymorphism (S-allele) within the promoter region of the 5-HTT gene (5-HTTLPR) confers lower transcriptional activity relative to the long allele (L-allele) and may act to modify the risk of serotonin-mediated outcomes such as anxiety and substance use behaviours. The purpose of this study was to determine whether (or not) 5-HTTLPR genotypes moderate known associations between attachment style and adolescent anxiety and alcohol use outcomes. Participants were drawn from an eight-wave study of the mental and behavioural health of a cohort of young Australians followed from 14 to 24 years of age (Victorian Adolescent Health Cohort Study, 1992 - present). No association was observed within low-risk attachment settings. However, within risk settings for heightened anxiety (ie, insecurely attached young people), the odds of persisting ruminative anxiety (worry) decreased with each additional copy of the S-allele (approximately 30% per allele: OR 0.77, 95% CI 0.62-0.97, P=0.029). Within risk settings for binge drinking (ie, securely attached young people), the odds of reporting persisting high-dose alcohol consumption (bingeing) decreased with each additional copy of the S-allele (approximately 35% per allele: OR 0.74, 95% CI 0.64-0.86, P<0.001). Our data suggest that the S-allele is likely to be important in psychosocial development, particularly in those settings that increase risk of anxiety and alcohol use problems.

Rates and predictors of mental illness in gay men, lesbians and bisexual men and women: Results from a survey based in England and Wales

BACKGROUND

There is a dearth of research into the mental health of gay men, lesbians and bisexual men and women in the UK.

AIMS

To assess rates and possible predictors of mental illness in these groups.

METHOD

A comprehensive assessment was made of the psychological and social well-being of a sample of gay men, lesbians and bisexual men and women, identified using 'snowball' sampling.

RESULTS

Of the 1285 gay, lesbian and bisexual respondents who took part, 556 (43%) had mental disorder as defined by the revised Clinical Interview Schedule (CIS - R). Out of the whole sample, 361 (31%) had attempted suicide. This was associated with markers of discrimination such as recent physical attack (OR=1.7, 95% CI 1.3-2.3) and school bullying (OR=1.4, 95% CI 1.1-2.0), but not with higher scores on the CIS-R.

CONCLUSIONS

Gay, lesbian and bisexual men and women have high levels of mental disorder, possibly linked with discrimination.

Teenage drinking and the onset of alcohol dependence: a cohort study over seven years

AIM

To determine whether adolescent alcohol use and/or other adolescent health risk behaviour predisposes to alcohol dependence in young adulthood.

DESIGN

Seven-wave cohort study over 6 years.

PARTICIPANT

A community sample of almost two thousand individuals followed from ages 14-15 to 20-21 years.

OUTCOME MEASURE

Diagnostic and Statistical Manual volume IV (DSM-IV) alcohol dependence in participants aged 20-21 years and drinking three or more times a week.

FINDINGS

Approximately 90% of participants consumed alcohol by age 20 years, 4.7% fulfilling DSM-IV alcohol dependence criteria. Alcohol dependence in young adults was preceded by higher persisting teenage rates of frequent drinking [odds ratio (OR) 8.1, 95% confidence interval (CI) 4.2, 16], binge drinking (OR 6.7, 95% CI 3.6, 12), alcohol-related injuries (OR 4.5 95% CI 1.9, 11), intense drinking (OR 4.8, 95% CI 2.6, 8.7), high dose tobacco use (OR 5.5, 95% CI 2.3, 13) and antisocial behaviour (OR 5.9, 95% CI 3.3, 11). After adjustment for other teenage predictors frequent drinking (OR 3.1, 95% CI 1.2, 7.7) and antisocial behaviour (OR 2.4, 95% CI 1.2, 5.1) held persisting independent associations with later alcohol dependence. There were no prospective associations found with emotional disturbance in adolescence.

CONCLUSION

Teenage drinking patterns and other health risk behaviours in adolescence predicted alcohol dependence in adulthood. Prevention and early intervention initiatives to reduce longer-term alcohol-related harm therefore need to address the factors, including alcohol supply, that influence teenage consumption and in particular high-risk drinking patterns.

The role of information technology in evidenced-based practice

Clinical Computing is a natural tool for evidence-based practice. Automated self-report produces accurate clinical assessments both in research and clinical settings, thus assuring that patients in each satisfy the same symptom criteria. The Electronic Medical Record (EMR) eventually will form a real-time Information bridge between research and clinical settings. Despite substantial literature demonstrating the efficacy of clinical computing in psychiatric care and research, however, psychiatrists have been slow to adopt computers, and research has dwindled. The steady emergence of system-wide EMRs, will spark a resurgence.

Mental health and quality of life of gay men and lesbians in England and Wales: controlled, cross-sectional study

BACKGROUND

Little is known about the mental health of gay men and lesbians living in Europe.

AIMS

To compare psychological status, quality of life and use of mental health services by lesbians and gay men with heterosexual people.

METHOD

Cross-sectional study in England and Wales using 'snowball' sampling.

PARTICIPANTS

656 gay men, 505 heterosexual men, 430 lesbians and 588 heterosexual women. Gay men were more likely than heterosexual men to score above threshold on the Clinical Interview Schedule, indicating greater levels of psychological distress (RR 1.24, 95% CI 1.07-1.43), as were lesbians compared with heterosexual women (RR 1.30, 95% CI 1.11-1.52). Gay men and lesbians were more likely than heterosexuals to have consulted a mental health professional in the past, deliberately harmed themselves and used recreational drugs. Lesbians were more likely to have experienced verbal and physical intimidation and to consume more alcohol than heterosexual women.

CONCLUSIONS

Awareness of mental health issues for gay men and lesbians should become a standard part of training for mental health professionals, who need to be aware of the potential for substance misuse and self-harm in this group and of the discrimination experienced by many lesbians.

Measures of short-term test-retest reliability of computerized neurobehavioral tests

Neurobehavioral test batteries are often administered repeatedly to evaluate changes over time or effects of clinical interventions or neurotoxic exposures. Time intervals between test sessions range from very short (hours) to very long (decades). The aim of this study was to compare the impact of two brief time intervals on the test-retest reliability of frequently used neurobehavioral tests. Fifty healthy adults were recruited through newspaper advertisements in Portland, Oregon. Participants were divided into either a 6h (same-day) or 1-week retest group. All participants completed a battery of tests from the computerized Behavioral Assessment and Research System (BARS). Reliability was assessed by Pearson product-moment correlation and by intraclass correlation coefficient (ICC). The test battery generally showed adequate reliability in the short-term (week) and very short-term (day) and stability in performance over repeated administration when examined by multiple measures. Intraclass correlation coefficient ranged from 0.35 to 0.85. The magnitude of variation of performance in the administered tests was equally distributed around zero (i.e. no difference). The findings suggest that neurobehavioral tests such as BARS may be a useful tool for the assessment of acute exposures and clinical status where short-term evaluation is required (e.g. in the same-day or within 1 week).

Mental health of British farmers

AIMS

To estimate the prevalence of neurotic symptoms in a sample of British farmers, to investigate whether farming characteristics are associated with psychiatric morbidity, and to test the hypothesis that British farmers have a higher prevalence of depression and thoughts of life not worth living than the British household population.

METHODS

A total of 425 farmers from Hereford, Norwich, and Preston completed the Revised Clinical Interview Schedule (CIS-R) by computer between March and July 1999. The comparison cohort consisted of 9830 private householders aged 16-64 from the Office of Population Censuses and Surveys National Psychiatric Morbidity Surveys of Great Britain carried out in 1993 in which the CIS-R was administered. All analyses used the commands developed specifically for survey data available in Stata version 6.0.

RESULTS

Taking a threshold of an overall score of 12 or more on the CIS-R, only 6% of farmers reported clinically relevant psychiatric morbidity. Psychiatric morbidity was not significantly associated with farm type or size in this study. Farmers reported a lower prevalence of psychiatric morbidity than the general population but were more likely to report thinking that life is not worth living, particularly after the low prevalence of psychiatric morbidity had been taken into account (odds ratio 2.56, 95% CI 1.39 to 4.69). When restricting the comparison to only rural or semirural householders, this increased risk was even more pronounced (odds ratio 3.26, 95% CI 1.51 to 7.02).

CONCLUSIONS

The relation between depression and suicidal ideation seems to be quite different among farmers and the general population and warrants further investigation. We have shown it is possible to measure mental health systematically in a sample of British farmers. This study should be repeated in the aftermath of the foot and mouth crisis.

An examination of perceptual and cognitive set shifting tasks in acute anorexia nervosa and following recovery

OBJECTIVES

People with anorexia nervosa have a broad spread of symptoms including disturbances in perception, cognition, emotions and behaviour. The aim of this study was to examine tests of executive function (in particular, perceptual and cognitive set shifting tasks) in patients with a current or past diagnosis of anorexia nervosa (AN).

METHOD

30 AN patients, 16 subjects recovered from anorexia nervosa (ANR) and 23 healthy controls were examined using tests of executive function (initiation tasks and perceptual and cognitive set shifting).

RESULTS

The AN and ANR subjects had significantly higher perceptual and cognitive set shifting scores than the controls.

CONCLUSIONS

Impaired executive function in terms of set shifting tasks could represent a vulnerability factor for AN.

Does bullying cause emotional problems? A prospective study of young teenagers

OBJECTIVES

To establish the relation between recurrent peer victimisation and onset of self reported symptoms of anxiety or depression in the early teen years.

DESIGN

Cohort study over two years.

SETTING

Secondary schools in Victoria, Australia.

PARTICIPANTS

2680 students surveyed twice in year 8 (aged 13 years) and once in year 9.

MAIN OUTCOME MEASURES

Self reported symptoms of anxiety or depression were assessed by using the computerised version of the revised clinical interview schedule. Incident cases were students scoring >/=12 in year 9 but not previously. Prior victimisation was defined as having been bullied at either or both survey times in year 8.

RESULTS

Prevalence of victimisation at the second survey point in year 8 was 51% (95% confidence interval 49% to 54%), and prevalence of self reported symptoms of anxiety or depression was 18% (16% to 20%). The incidence of self reported symptoms of anxiety or depression in year 9 (7%) was significantly associated with victimisation reported either once (odds ratio 1.94, 1.1 to 3.3) or twice (2.30, 1.2 to 4.3) in year 8. After adjustment for availability of social relations and for sociodemographic factors, recurrent victimisation remained predictive of self reported symptoms of anxiety or depression for girls (2.60, 1.2 to 5.5) but not for boys (1.36, 0.6 to 3.0). Newly reported victimisation in year 9 was not significantly associated with prior self report of symptoms of anxiety or depression (1.48, 0.4 to 6.0).

CONCLUSION

A history of victimisation and poor social relationships predicts the onset of emotional problems in adolescents. Previous recurrent emotional problems are not significantly related to future victimisation. These findings have implications for how seriously the occurrence of victimisation is treated and for the focus of interventions aimed at addressing mental health issues in adolescents.

Randomised controlled trial of non-directive counselling, cognitive-behaviour therapy, and usual general practitioner care for patients with depression. I: clinical effectiveness

OBJECTIVE

To compare the clinical effectiveness of general practitioner care and two general practice based psychological therapies for depressed patients.

DESIGN

Prospective, controlled trial with randomised and patient preference allocation arms.

SETTING

General practices in London and greater Manchester.

PARTICIPANTS

464 of 627 patients presenting with depression or mixed anxiety and depression were suitable for inclusion.

INTERVENTIONS

Usual general practitioner care or up to 12 sessions of non-directive counselling or cognitive-behaviour therapy provided by therapists.

MAIN OUTCOME MEASURES

Beck depression inventory scores, other psychiatric symptoms, social functioning, and satisfaction with treatment measured at baseline and at 4 and 12 months.

RESULTS

197 patients were randomly assigned to treatment, 137 chose their treatment, and 130 were randomised only between the two psychological therapies. All groups improved significantly over time. At four months, patients randomised to non-directive counselling or cognitive-behaviour therapy improved more in terms of the Beck depression inventory (mean (SD) scores 12.9 (9.3) and 14.3 (10.8) respectively) than those randomised to usual general practitioner care (18.3 (12.4)). However, there was no significant difference between the two therapies. There were no significant differences between the three treatment groups at 12 months (Beck depression scores 11.8 (9.6), 11.4 (10.8), and 12.1 (10.3) for non-directive counselling, cognitive-behaviour therapy, and general practitioner care).

CONCLUSIONS

Psychological therapy was a more effective treatment for depression than usual general practitioner care in the short term, but after one year there was no difference in outcome.

Onset of adolescent eating disorders: population based cohort study over 3 years

OBJECTIVE

To study the predictors of new eating disorders in an adolescent cohort.

DESIGN

Cohort study over 3 years with six waves.

SUBJECTS

Students, initially aged 14-15 years, from 44 secondary schools in the state of Victoria, Australia.

OUTCOME MEASURES

Weight (kg), height (cm), dieting (adolescent dieting scale), psychiatric morbidity (revised clinical interview schedule), and eating disorder (branched eating disorders test). Eating disorder (partial syndrome) was defined when a subject met two criteria for either anorexia nervosa or bulimia nervosa according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV).

RESULTS

At the start of the study, 3.3% (29/888) of female subjects and 0.3% (2/811) of male subjects had partial syndromes of eating disorders. The rate of development of new eating disorder per 1000 person years of observation was 21.8 in female subjects and 6.0 in male subjects. Female subjects who dieted at a severe level were 18 times more likely to develop an eating disorder than those who did not diet, and female subjects who dieted at a moderate level were five times more likely to develop an eating disorder than those who did not diet. Psychiatric morbidity predicted the onset of eating disorder independently of dieting status so that those subjects in the highest morbidity category had an almost sevenfold increased risk of developing an eating disorder. After adjustment for earlier dieting and psychiatric morbidity, body mass index, extent of exercise, and sex were not predictive of new eating disorders.

CONCLUSIONS

Dieting is the most important predictor of new eating disorders. Differences in the incidence of eating disorders between sexes were largely accounted for by the high rates of earlier dieting and psychiatric morbidity in the female subjects. In adolescents, controlling weight by exercise rather than diet restriction seems to carry less risk of development of eating disorders.
