Burden of Alzheimer's Disease: Population-Based Estimates and Projections for New Zealand, 2006–2031
Authors: Tobias Martin , Yeh Li-Chia , Johnson Elizabeth 
Published: December 2009

Objective: To estimate the burden of Alzheimer's disease (AD, including ‘mixed’ dementia) in New Zealand in 2006, and project this burden out to 2031. Method: An incidence to prevalence methodology was utilized, the foundation of which is a discrete time Markov model allowing for multiple stages of disease (early vs late). Population estimates and projections, and all-cause mortality rates, were obtained from Statistics New Zealand. In the absence of usable New Zealand data, data on disease incidence and progression were obtained from systematic reviews of the international (mainly European, Australian and North American) literature. Projection scenarios included a demographic scenario in which change resulted only from increases in population size and ageing; a prevention scenario in which incidence rates were reduced by 25% from 2011; a treatment scenario in which disease progression rates were likewise reduced by 25% from 2011; and a combined scenario capturing both interventions. Results: The model estimated that approximately 28000 people are currently living with AD (whether formally diagnosed or not), approximately 55% in the early and 45% in the late stage of the disease; approximately 6600 people newly develop AD each year; and approximately 2300 people die from (as opposed to with) this condition. The model projected that the prevalence of AD will increase approximately 2.5-fold (to approx. 70000 people) by 2031, if demographic drivers are unopposed. Plausible improvements in prevention and treatment, however, acting together, could reduce this growth by up to 50%, so that the prevalence of AD only doubles. Conclusion: Even this more optimistic projection has profound implications for the funding and provision of dementia care services, as well as for patients, their families, informal carers and the psychogeriatric workforce. New service configurations and models of care will be necessary. Access, quality and coordination standards for home care, day care, respite care, residential care and specialist services (including memory clinics) will need to respond accordingly.

Authors: Torr Jennifer , Lennox Nicholas , Cooper Sally-Ann , Rey-Conde Therese , Ware Robert S. , Galea Jennifer , Taylor Miriam 
Published: December 2009

Objective: In light of developments in training and service provision, the aim of the present study was to compare two state-wide surveys, undertaken in 1994 and in 2004, of psychiatrists about their perceptions of their training and psychiatric treatment of adults with intellectual disabilities who also have mental health needs. Methods: A 50-item self-administered questionnaire was developed for the 2004 survey, based on the 1994 study. This was sent to all 624 Fellows of the Royal Australian and New Zealand College of Psychiatry registered in Victoria at the time. A series of questions was asked based on workload, training, the role of psychiatry in intellectual disabilities, opinions on assessment and management, improving services, and the demographics of participant psychiatrists. Results of the 2004 survey are compared with the 1994 study. Results: There has been some change in psychiatrists’ opinions about acute admission wards, believing strongly that they do not meet the needs of the adults with severe intellectual disabilities, leaving them vulnerable to exploitation. There has been some improvement in their ability to adequately manage adults with intellectual disabilities who have mental health needs and/or problem behaviours. Conclusions: Mainstream mental health services fail to meet the needs of adults with intellectual disabilities. Improved specialist clinical services and more clinical training opportunities are required.
Prevalence of Transsexualism Among New Zealand Passport Holders
Authors: Veale Jaimie F. 
Published: December 2009

Objective: Most previous studies of the prevalence of transsexualism have used data from individuals seeking sex reassignment surgery. New Zealand is unique in that transsexual people can apply to have an ‘X’ for the sex on their passport if they have a name on their birth certificate that is congruent with the sex opposite to their birth assigned sex, and provide a statutory declaration stating they have lived as a member of that sex. Method: From information provided by the New Zealand Passports Office, it was ascertained that the prevalence of transsexualism among New Zealand passport holders was at least 1:6364. Results: The prevalence of male-to-female transsexualism was estimated at 1:3639, and the corresponding figure for female-to-male transsexualism was 1:22 714. Conclusions: These estimates were higher than most previous estimates of transsexualism prevalence. There was also a larger than expected ratio of male-to-female transsexual people to female-to-male transsexual people (6:1), which could in part be due to female-to-male transsexual people being relatively overrepresented among those transsexual people for whom we did not have data on the direction of sex change, or this may be indicative of the demography of transsexualism in Australasia.

Published: December 2009

Objective: The aim of the present study was to examine the reliability and validity of the short form of the Reynolds Adolescent Depression Scale (RADS-SF). Method: A sample of 9567 randomly selected New Zealand secondary school students participated in the Youth2000 Health and Wellbeing Survey that included the full-length version of the RADS. The reliability and validity of the subset of items that make up the RADS-SF and its comparability to the original version were assessed using Cronbach's alpha, kappa statistics, correlations between the two versions of the instrument, confirmatory factor analysis and correlation to other questions in the survey considered likely to be associated with depression. Results: The RADS-SF had Cronbach's alpha of 0.88, was strongly correlated (0.95) to the RADS, had acceptable fit for the data (χ2=2823.27, df=35, comparative fit index=0.96, root mean square error of approximation=0.092, 90% confidence interval=0.089–0.095, standardized root mean square residual=0.042), showed configural invariance across gender, age and ethnic groups, and was strongly correlated with other depression-related questions, such as suicidal ideation (r=0.48). While the overall agreement for classification of depression by the two scores was good (κ=0.75), a higher percentage of students were classified as having depressive symptoms using the recommended RADS-SF cut-off point of 26 compared with the RADS criteria. Conclusions: The RADS-SF was found to have acceptable reliability and validity and to have psychometric properties comparable to the RADS in a large population of New Zealand adolescents.
Temperament, Substance Use and Psychopathology in a Prisoner Population: Implications for Treatment
Authors: Allnutt Stephen , Wedgwood Lucinda , Wilhelm Kay , Butler Tony 
Published: December 2009

Objective: The association between temperament and drug use or temperament and psychopathology has previously been restricted to community clinical or non-clinical samples. The aim of the present study was therefore to examine these associations in a large cohort of Australian offenders using Cloninger's Temperament and Character Inventory (TCI). Methods: A total of 1322 prisoners from New South Wales (NSW) who completed all dimensions of the TCI and were screened for mental illness using the Australian National Survey of Mental Health and Wellbeing were included in the study. Results: A total of 15% of the sample fulfilled the criteria for a diagnosis for depression, 36% for anxiety disorders and 54% for a substance abuse disorder. Using logistic regression analysis, the TCI dimensions of harm-avoidance and low self-direction predicted depression. Being female, a poly-substance user and having high harm-avoidance, persistence, self-direction and self-transcendence predicted anxiety disorders. Significant stepped trends across age, gender, and type of drug use were found for all TCI dimensions. Conclusions: The TCI is useful in identifying prisoners with a history of psychopathology and substance misuse. This tool also provides clinically relevant information about at-risk individuals and has the potential to guide the development of intervention programmes for inmates.
Reasons for Cannabis Use: Patients with Schizophrenia Versus Matched Healthy Controls
Authors: Schaub Michael , Fanghaenel Kyra , Stohler Rudolf 
Published: December 2009

Objective: The aim of the present study was to compare self-reported reasons for cannabis use in patients with schizophrenia with those of matched healthy controls. Methods: Thirty-six stable outpatients with schizophrenia treated with atypical antipsychotics and 36 matched controls were included. They completed a questionnaire exploring 15 common reasons for use, established in other studies. Results: Overall, patients more frequently agreed with the proposed reasons for use than controls. More specifically, patients with schizophrenia more often stated that they consumed cannabis to fight boredom and to ease social contacts. Conclusions: Stable schizophrenia outpatients treated with atypicals do not use cannabis in order to reduce side-effects of medication or symptoms of their disorder. Rather, they used cannabis to overcome a feeling of social exclusion. Therefore, enhancing social participation of cannabis-using patients might be an effective strategy for reducing consumption.
Evaluation of a Resilience-Based Intervention for Children of Parents With Mental Illness
Authors: Fraser Eliza , Pakenham Kenneth I. 
Published: December 2009

Objective: The purpose of the present study was to evaluate the effectiveness of a group psychosocial intervention for children (aged 12–18) of a parent with mental illness (copmi). Method: A treatment and waitlist-control design study with pre- and post-treatment, and 8 week follow up, was carried out. The treatment (n = 27) and control (n=17) groups were compared on three groups of dependent variables: intervention targets (mental health literacy, connectedness, coping strategies), adjustment (depression, life satisfaction, prosocial behaviour, emotional/behavioural difficulties), and caregiving experiences. Results: Group comparisons failed to show statistically significant intervention effects, but reliable clinical change analyses suggested that compared to the control group, more intervention participants had clinically significant improvements in mental health literacy, depression, and life satisfaction. These treatment gains were maintained 8 weeks after treatment. Participant satisfaction data supported these treatment gains. Conclusions: Given study limitations and the modest support for intervention effectiveness it is important that this and other similar interventions should continue to be revised and undergo rigorous evaluation.
Psychological Distress and Its Demographic Associations in an Immigrant Population: Findings from the Israeli National Health Survey
Authors: Ponizovsky Alexander M. , Radomislensky Ira , Grinshpoon Alexander 
Published: December 2009

Objective: This study compared psychological distress and its sociodemographic correlates in immigrant and veteran Israeli populations using data from the Israel National Mental Health Survey, the first nationwide study designed to estimate the prevalence rates of psychological distress and mental disorders in the Israeli adult population, which was carried out in 2003–2004, in conjunction with the World Mental Health survey initiative. Method: Personal interviews were held with 3906 veteran Israelis, 845 immigrants from the former Soviet Union (FSU) and 107 immigrants from other countries (all the immigrants immigrated after 1989). Psychological distress was measured on the General Health Questionnaire-12. Results: Psychological distress among FSU immigrants was significantly higher than among veteran Israelis and immigrants from elsewhere. FSU immigrants were almost twice as likely to report severe psychological distress. Factors associated with psychological distress were female gender, age above 50, being divorced/widowed, being secular, having higher education and being either unemployed or ‘not in workforce’. Conclusion: The results support the acculturation stress hypothesis as an explanation for psychological distress in immigrants only in immigrants from the FSU, indicating that policymakers should plan services and prevention programmes differentially for different immigrant populations.
Growth in Young Adults Who Screen Positive for Non-Affective Psychosis: Birth Cohort Study
Authors: Welham Joy , Scott James , Williams Gail , Najman Jake , O'Callaghan Michael , McGrath John 
Published: December 2009

Objective: While birth cohort studies have shown that individuals who develop non-affective psychosis show subtle deviations in cognitive and behavioural developmental trajectories, there is less evidence about deviations in physical growth in these individuals. The purpose of the present study was to examine the association between behaviour and growth and maturation from infancy, through childhood and adolescence to early adulthood and the development of non-affective psychosis in young adults. Method: Based on a birth cohort of 3801 young adults, weight and length/height were examined at birth and at years 5, 14 and 21, together with pubertal maturation at year 14. Behavioural measures taken at years 5 and 14 were also examined. Screen-positive non-affective psychosis (SP-NAP) was assessed at year 21 using Composite International Diagnostic Interview, or a self-report checklist. The association between the behavioural and growth measures at birth and at years 5, 14 and 21, and SP-NAP at year 21 was examined using logistic regression. Results: There were 60 subjects in the cohort who were classified as having SP-NAP. In female subjects SP-NAP was significantly associated with being longer with a larger head circumference at birth, and less likely to be associated with being shorter at 21 years, with consistent trend associations for height between. There were no differences for weight. There was no significant association between the variables of interest in male subjects or for the total group. There was also no significant association between pubertal development at age 14 and risk of SP-NAP in either sex. Conclusions: Unlike developmental behavioural problems, which showed continuity from childhood through adolescence, SP-NAP was not associated with marked deviations in growth trajectory for male subjects, but the present data suggests that female subjects with SP-NAP had an altered skeletal growth trajectory.

Published: December 2009

Objective: Given the association between severe childhood trauma, adult somatization and complex post-traumatic stress disorder (cPTSD), the purpose of the present paper was to assess this syndrome and its clinical correlates in patients with somatization disorder (SD). Methods: A total of 28 patients (82% women, mean age = 41.7±10.1 years) meeting DSM-IV criteria for SD as confirmed by the Structured Clinical Interview for DSM-IV, Axis I were compared to 28 age- and gender-matched patients with major depression, but without a lifetime diagnosis of SD. They completed the Structured Interview for Disorders of Extreme Stress, the Brief Symptom Inventory, the Inventory of Interpersonal Problems–Circumplex Scales, and the SF-36 Health Survey. Results: Compared to the control group, SD patients had higher risks for current and lifetime diagnoses of cPTSD (odds ratio (OR) = 15.0, 95% confidence interval (CI) = 1.76–127.54; and OR = 8.33, 95%CI = 2.04–34.07, respectively). SD subjects with cPTSD had more psychological distress, more interpersonal problems and worse psychosocial functioning than those without the syndrome. Conclusion: The concept of complex PTSD may hold clinical utility when applied to SD patients because it identifies a distinct subgroup characterized by severe psychosocial impairment. The diagnostic and therapeutic implications of the present findings are discussed.
Preliminary Data on the Efficacy of the Incredible Years Basic Parent Programme in New Zealand
Authors: Fergusson David , Stanley Lesley , Horwood L. John 
Published: December 2009

Objective: The aim of the present study was to conduct a preliminary examination of the efficacy and cultural acceptability of the Incredible Years Basic Parent Programme (IYBPP Au: (abstract objective) please confirm change of IYBPP definition to ‘Incredible Years Basic) using data provided by the New Zealand Ministry of Education. Methods: Data were gathered on a series of 214 parents attending IYBPP for at least nine sessions. These data included (i) pre-test and post-test T scores on the Eyberg intensity and problem scales; (ii) pre-test and post-test scores on the parent version of the child Social Competence Scale; and (iii) parent satisfaction ratings. Results: Pre-test–post-test comparisons indicated significant improvements in behaviour and social competence scores (p<0.001). Effect sizes ranged from 0.50 to 0.77. Effects were similar for Maori and non-Maori subjects. Parental satisfaction with the programme was high, with Maori and non-Maori parents reporting similar levels of satisfaction. Conclusions: These preliminary data are consistent with the view that IYBPP is an effective and culturally appropriate programme. There is a need for a more comprehensive evaluation using pilot research to assess the fidelity of programme delivery and randomized trials to assess programme efficacy.
Association Between Magnesium Intake and Depression and Anxiety in Community-Dwelling Adults: The Hordaland Health Study
Authors: Jacka Felice N. , Overland Simon , Stewart Robert , Tell Grethe S. , Bjelland Ingvar , Mykletun Arnstein 
Published: December 2009

Objective: Systemic inflammation is associated with both the dietary intake of magnesium, and depression. Limited experimental and clinical data suggest an association between magnesium and depression. Thus, there are reasons to consider dietary magnesium as a variable of interest in depressive disorders. The aim of the present study was to examine the association between magnesium intake and depression and anxiety in a large sample of community-dwelling men and women. This sample consisted of 5708 individuals aged 46–49 or 70–74 years who participated in the Hordaland Health Study in Western Norway. Methods: Symptoms of depression and anxiety were self-reported using the Hospital Anxiety and Depression Scale, and magnesium intake was assessed using a comprehensive food frequency questionnaire. Results: There was an inverse association between standardized energy-adjusted magnesium intake and standardized depression scores that was not confounded by age, gender, body habitus or blood pressure (β=−0.16, 95% confidence interval (CI)=−0.22 to −0.11). The association was attenuated after adjustment for socioeconomic and lifestyle variables, but remained statistically significant (β=−0.11, 95%CI=−0.16 to −0.05). Standardized magnesium intake was also related to case-level depression (odds ratio (OR)=0.70, 95%CI=0.56–0.88), although the association was attenuated when adjusted for socioeconomic and lifestyle factors (OR=0.86, 95%CI=0.69–1.08). The inverse relationship between magnesium intake and score and case-level anxiety was weaker and not statistically significant in the fully adjusted models. Conclusion: The hypothesis that magnesium intake is related to depression in the community is supported by the present findings. These findings may have public health and treatment implications.

Published: December 2009

Objective: The validity of the diagnosis of chronic fatigue syndrome and related chronic fatigue states remains controversial, particularly in psychiatry. This project utilized international epidemiological and clinical research data to test construct validity across diagnostic categories, health-care settings and countries. Relevant demographic, symptom and diagnostic data were obtained from 33 studies in 21 countries. The subjects had fatigue lasting 1–6 months (prolonged fatigue), or >6 months (chronic fatigue), or met diagnostic criteria for chronic fatigue syndrome. Method: Common symptom domains were derived by factor analytic techniques. Mean scores on each symptom factor were compared across diagnostic categories, health-care settings and countries. Results: Data were obtained on 37 724 subjects (n = 20 845 female, 57%), including from population-based studies (n = 15 749, 42%), studies in primary care (n = 19 472, 52%), and secondary or specialist tertiary referral clinics (n = 2503, 7%). The sample included 2013 subjects with chronic fatigue, and 1958 with chronic fatigue syndrome. A five-factor model of the key symptom domains was preferred (‘musculoskeletal pain/fatigue’, ‘neurocognitive difficulties’, ‘inflammation’, ‘sleep disturbance/fatigue’ and ‘mood disturbance’) and was comparable across subject groups and settings. Although the core symptom profiles were similar, some differences in symptoms were observed across diagnostic categories, health-care settings and between countries. Conclusions: The construct validity of chronic fatigue and chronic fatigue syndrome is supported by an empirically derived factor structure from existing international datasets.
Adult Attachment Styles in Panic Disorder with and Without Comorbid Adult Separation Anxiety Disorder
Authors: Manicavasagar Vijaya , Silove Derrick , Marnane Claire , Wagner Renate 
Published: December 2009

Objective: Attachment theory suggests that anxious attachment styles are associated with risk to psychiatric disorder, especially anxiety disorders. Separation anxiety would appear to be a core form of anxiety that is associated with anxious attachment. Nevertheless, as yet no research has examined the relationship of attachment styles to adult separation anxiety disorder, a condition that has only recently been fully recognized. Method: The Attachment Style Questionnaire was used to examine attachment styles among 83 consecutive anxiety clinic patients diagnosed with panic disorder with agoraphobia and those re-assigned from that category to adult separation anxiety disorder. Results: Dimensional associations showed strong correlations with scales measuring anxious attachment and separation anxiety. Patients assigned to the separation anxiety group scored significantly higher than those in the panic disorder group on the scales of Need for Approval and Preoccupation with Relationships. Conclusions: The findings finally dispel the notion that separation anxiety and anxious attachment are relevant to panic disorder with agoraphobia, suggesting instead that that constellation is confined to a separate group, namely that of adult separation anxiety disorder. Possible implications for treatment are considered.
