Parent-child concordance for separation anxiety: a clinical study.

There is tentative evidence supporting a familial basis for separation anxiety. The present study aimed to examine parent-child concordance for that subtype of anxiety. Fifty-four children diagnosed with anxiety disorders and their parents (54 mothers and 29 fathers) were recruited from two juvenile anxiety clinics. Sixty-three percent of children diagnosed with juvenile separation anxiety disorder had at least one parent who suffered from the putative adult variant of the disorder (odds ratio = 11.1) (P < 0.001). Affected parents reported high levels of separation anxiety in their own childhoods. Juvenile separation anxiety disorder in children was not associated with any other parental diagnosis. The small sample size and other potential biases caution against definitive conclusions being drawn, but the present data add to existing evidence that separation anxiety may aggregate in families.

Agreement in symptoms of anxiety and depression between patients and GPs: the influence of ethnicity.

BACKGROUND: Few studies have focused specifically on the role of ethnicity in the identification and treatment of anxiety and depressive symptoms among patients consulting GPs. METHODS: A survey was conducted of 4753 patients aged 18-90 years attending general practices in Sydney, Australia. Three methods of case detection were used: a GHQ-12 score (> or = 3), self-report symptoms (using a checklist) and GP detection of symptoms. Four regional groupings based on country of birth [other English speaking countries (ESB), European, Asian (predominantly south east Asian) and other non-English speaking (other NESB)] were compared with Australian (AB) patients. RESULTS: Compared with AB patients, Asian patients had a lower mean GHQ-12 score (2.04 versus 2.54) and a lower rate of GP detection (10.4% versus 20.5%) but they recorded a similar rate of self-report symptoms (16.7% versus 20.1%). For Asian patients, 24.6% of all cases identified by self-report or by GP detection were identified by both methods, compared with 44% for AB patients. Similar patterns of treatment and referral were observed for detected cases. Compared with AB patients, Asian and other NESB patients were more likely to desire more time to discuss their problems with their GP (18.5% versus 42.0%, 37.3%) and receive an explanation of medications prescribed (18.9% versus 46%, 40.0%). CONCLUSION: These results suggest that there are substantial variations in the rates of detection of anxiety and depressive symptoms in GP patients depending on the screening methods used and the broad ethnic background of patients. Such symptoms may be under-diagnosed in Asian patients in particular.

Prevalence, detection and management of anxiety and depressive symptoms in unemployed patients attending general practitioners.

INTRODUCTION: This study examined the detection and management of anxiety and depressive symptoms among unemployed patients attending general practitioners (GPs). METHOD: A cross-sectional study was undertaken of anxiety and depressive symptoms in general practice using measures completed by patients and GPs. Eligible patients were adults aged 18 to 64 years either working (n = 2273) or unemployed (n = 392). RESULTS: Eighty per cent of patients were attending their regular GP at the time of the study. Unemployed patients were found to have a higher mean general health questionnaire (GHQ-12) score than employed patients (3.8 compared with 2.4, p < 0.001); were more likely to report symptoms of anxiety and depression which required medical treatment during the previous 4weeks (30.9% compared with 14.6%, p < 0.001); and were more likely to have been treated for anxiety and depression by the GP (27.8% compared with 15.7%, p < 0.001). Among patients who the GPs reported treating for anxiety and depression, unemployed patients were 3.3 times (95% CI: 2.0-5.4) more likely to be prescribed medication than employed patients when severity was controlled but were no more likely to be referred to other health services. Unemployed patients identified increased use of services and were less satisfied with the care that they had received. CONCLUSIONS: Unemployed patients attending GPs have an increased risk of anxiety and depressive symptoms. Increased prescription of medication as opposed to referral suggests that GPs may treat their unemployed patients differently to employed patients. GPs need to be aware of the higher risk and severity of anxiety and depressive symptoms among unemployed patients and their desire to be more actively involved in their treatment. General practice is an important setting for addressing the health needs of unemployed people.

Parental representations associated with adult separation anxiety and panic disorder--agoraphobia.

OBJECTIVE: Early bonding abnormalities have been associated with a range of anxiety and depressive disorders in adulthood, but no specific parental patterns have emerged for particular disorders. The present study investigated the possibility that parental overprotectiveness may be linked to a risk of separation anxiety (SA) in adulthood. METHOD: Two samples were recruited: volunteers (n = 34) whose major anxieties focused on separation concerns, and adult anxiety clinic patients (n = 37) who were diagnosed with panic disorder. Parental characteristics and early SA were assessed by dichotomising the combined sample first according to adult SA categorisation and then by panic disorder status. RESULTS: Subjects assigned to the adult SA category reported high levels of juvenile SA and exposure to maternal overprotectiveness, whereas patients diagnosed with panic disorder reported few differences in their bonding histories compared to residual anxious patients. CONCLUSIONS: The findings of this study suggest that early SA and parental overprotectiveness may not be associated with panic disorder per se, but rather with persisting SA symptoms in adulthood. The overlapping samples and retrospectivity of some measures are important limitations of the study.

Subpopulations of early separation anxiety: relevance to risk of adult anxiety disorders.

BACKGROUND: The present study aims to examine whether discrete subpopulations can be identified according to their levels of early separation anxiety (SA), and if so, whether such a typology of SA influences risk to particular adult anxiety disorders. METHODS: Mixture analysis was applied to early SA scores provided retrospectively by a composite group (n=1800) of adult community and patient samples. The distribution of adult anxiety diagnoses across the SA categories was assessed in a community (n=136) and a clinic (n=74) sample. RESULTS: The mixture analysis yielded two subpopulations according to SA scores. Odds ratios for assignment to the high SA category for the various anxiety disorders ranged from 3.6 to 6.7. A logistic regression analysis revealed that when comorbidity was taken into account, the panic disorder-agoraphobia (PD-Ag) group was the only anxiety disorder to be associated with the high SA category. CONCLUSION: Assignment to a high early SA category appears to increase risk to adult anxiety disorders, particularly PD-Ag. Several possible pathways may account for such a risk including the persistence of separation anxiety disorder into adulthood. LIMITATIONS: Assessment of early SA was made using a retrospective measure and the samples included groups which were known to have high SA scores. CLINICAL RELEVANCE: Only a subpopulation of anxiety sufferers may have elevated levels of SA. Identification of this group may be important for early detection and intervention.

The Family Attitude Scale: reliability and validity of a new scale for measuring the emotional climate of families.

Research on outcomes from psychiatric disorders has highlighted the importance of expressed emotion (EE), but its cost-effective measurement remains a challenge. This article describes development of the Family Attitude Scale (FAS), a 30-item instrument that can be completed by any informant. Its psychometric characteristics are reported in parents of undergraduate students and in 70 families with a schizophrenic member. The total FAS had high internal consistency in all samples, and reports of angry behaviour in FAS items showed acceptable inter-rater agreement. The FAS was associated with the reported anger, anger expression and anxiety of respondents. Substantial associations between the parents' FAS and the anger and anger expression of students was also observed. Parents of schizophrenic patients had higher FAS scores than parents of students, and the FAS was higher if disorder duration was longer or patient functioning was poorer. Hostility, high criticism and low warmth on the Camberwell Family Interview (CFI) were associated with a more negative FAS. The highest FAS in the family was a good predictor of a highly critical environment on the CFI. The FAS is a reliable and valid indicator of relationship stress and expressed anger that has wide applicability.

Compounding of premigration trauma and postmigration stress in asylum seekers.

Unauthorized immigrants arriving in Western countries increasingly are being subjected to stringent restrictions while their residency claims are assessed. The present study was a investigation of premigration exposure to organized violence and postmigration stressors in 40 individuals seeking asylum who were attending a community welfare center in Sydney, Australia. Almost 80% reported exposure to premigration trauma such as witnessing murders, having their lives threatened, being separated from family members, and brainwashing; 25% had been tortured. Asylum seekers reported a marked decline in socioeconomic status. Common ongoing sources of severe stress included fears of being repatriated, barriers to work and social services, separation from family, and issues related to the process of pursuing refugee claims. More than one third had problems obtaining health services in Australia--the same number who reported similar difficulties in their home countries. Although based on a selective and culturally heterogeneous sample, the results suggest that salient aspects of the asylum-seeking process may compound the stressors suffered by an already traumatized group.

Satisfaction of Vietnamese patients and their families with refugee and mainstream mental health services.

OBJECTIVE: The study examined levels of satisfaction with mainstream mental health services and specialized mental health services for refugees among Vietnamese psychiatric patients and their relatives. Demographic, diagnostic, symptomatic, and service-related issues that might influence satisfaction were investigated. METHODS: Eighty-six Vietnamese patients were identified from case notes of mainstream inpatient services (N = 31), mainstream community services (N = 7), and a specialized refugee treatment unit (N = 48). During an interview, a scale measuring satisfaction with treatment as well as measures of anxiety, depression, and posttraumatic stress disorder was administered to them. A modified satisfaction scale was administered to 56 relatives. RESULTS: Patients and relatives were, on average, moderately satisfied with treatment. Patients expressed greater satisfaction with the specialized treatment unit for refugees than with mainstream services, a finding that was not influenced by diagnostic differences or symptom levels at the time patients responded. Further analyses controlling for multiple comparisons revealed that the extent of the information provided and the ease of negotiating changes in treatment were the most salient variables in distinguishing satisfaction levels across the two types of treatment centers. Patients' fluency in English and their relatives' level of education were inversely associated with satisfaction scores, tentatively suggesting that the greater the ability of patients and their families to evaluate services, the less likely they were to express satisfaction with treatment. CONCLUSIONS: Specialized mental health services for refugees may be more acceptable to refugee populations than their mainstream counterparts, perhaps because better communication with patients and their families is possible in the specialized services. Patients and families who are in a position to evaluate services fully are more likely to be critical of treatments offered.

Anxiety, depression and PTSD in asylum-seekers: assocations with pre-migration trauma and post-migration stressors.

BACKGROUND: Research into the mental health of refugees has burgeoned in recent times, but there is a dearth of studies focusing specifically on the factors associated with psychiatric distress in asylum-seekers who have not been accorded residency status. METHOD: Forty consecutive asylum-seekers attending a community resource centre in Sydney, Australia, were interviewed using structured instruments and questionnaires. RESULTS: Anxiety scores were associated with female gender, poverty, and conflict with immigration officials, while loneliness and boredom were linked with both anxiety and depression. Thirty subjects (79%) had experienced a traumatic event such as witnessing killings, being assaulted, or suffering torture and captivity, and 14 subjects (37%) met full criteria for PTSD. A diagnosis of PTSD was associated with greater exposure to pre-migration trauma, delays in processing refugee applications, difficulties in dealing with immigration officials, obstacles to employment, racial discrimination, and loneliness and boredom. CONCLUSIONS: Although based on correlational data derived from'a convenient' sample, our findings raise the possibility that current procedures for dealing with asylum-seekers may contribute to high levels of stress and psychiatric symptoms in those who have been previously traumatised.

Is there an adult form of separation anxiety disorder? A brief clinical report.

OBJECTIVE: The aim of this clinical report is to investigate whether symptoms of separation anxiety disorder can occur in adulthood. CLINICAL PICTURE: Three cases are described to illustrate that adults may experience: wide-ranging separation anxiety symptoms, such as extreme anxiety and fear, when separated from major attachment figures; avoidance of being alone; and fears that harm will befall those close to them. Symptoms of panic appeared to be secondary to separation anxiety, and none of the patients fulfilled criteria for dependent personality disorder. TREATMENT: Group cognitive behavioural treatment focusing on preventing panic attacks and generalised anxiety did not appear to have an impact on core separation anxiety symptoms. OUTCOME: Exacerbations of separation anxiety appeared to be closely linked to actual or threatened ruptures to primary bonds. CONCLUSIONS: Separation anxiety disorder may be a neglected diagnosis in adulthood. Formal nosological systems such as the DSM may need to be revised to incorporate adult manifestations of the disorder.

Anxiety and depression in general practice patients: prevalence and management.

OBJECTIVE: To determine the prevalence of anxiety and depression in general practice patients and assess management of these conditions by general practitioners (GPs). METHOD: A random sample of 212 GPs were approached to be interviewed and to conduct a patient survey and audit on 50 consecutive patient consultations during 1993. PARTICIPANTS: 117 GPs (55% response rate) and 4867 patients (85%) who completed questionnaires suitable for analysis. SETTING: General practices in two areas (divisions of general practice) in Sydney, New South Wales. RESULTS: Thirty-six per cent of patients had abnormal scores on a General Health Questionnaire (GHQ-12); they were more likely to be women or to be unemployed. Twenty per cent of these patients had been treated for depression or anxiety in the previous 12 months; 52% were prescribed drug therapy, and were more likely to be older, male or unemployed. Seventy per cent of patients reported having been offered therapy by their GP that did not involve drugs. Twenty-four per cent had been referred to another health professional; they were more likely to be younger, or men, or patients attending their usual doctor. CONCLUSIONS: A brief screening instrument may improve GPs' detection rate of patients with anxiety or depression. The high prevalence of these conditions in unemployed people deserves particular attention by GPs. Both drug and non-drug therapies are being more appropriately applied in general practice than previously.

Is early separation anxiety a specific precursor of panic disorder-agoraphobia? A community study.

The present study aimed to examine memories of early separation anxiety symptoms in a community sample of women at heightened risk to neurotic disorder. The chief finding was that subjects with a lifetime history of panic disorder-agoraphobia (PD-Ag) returned statistically higher scores on a retrospective measure of early separation anxiety compared to subjects with either generalized anxiety or other phobic disorders, a result which was not accounted for by differences in neuroticism or General Health Questionnaire scores. Although limited by its retrospective design and the problem of co-morbidity in subclassifying the anxiety disorders, the present study does provide added support for the hypothesis--endorsed by DSM-III-R--that there is a developmental link between early separation anxiety and panic disorder.

Genetic factors in early separation anxiety: implications for the genesis of adult anxiety disorders.

An important contemporary conceptualization of anxiety has suggested that heightened early separation anxiety is specifically associated with the risk of adult panic disorder, with hereditary factors underlying that cluster of anxiety disorders. Yet there is a dearth of studies examining whether early separation anxiety is inherited. The present twin study, based on a retrospective approach, revealed a substantial genetic contribution to separation anxiety in females but not in males, with unique environmental influences being important in both gender groups. Although speculative, an evolutionary explanation is offered to account for the apparent gender difference in the inheritance of early separation anxiety. It is hypothesized that, in some women, phylogenetic vestiges of separation anxiety may conflict with their need to compete in an individualistic manner in the modern workplace. Whether such an attachment-autonomy conflict accounts for the increased rate of panic disorder and agoraphobia in women is worthy of further study.

Impact of recounting trauma stories on the emotional state of Cambodian refugees.

Twenty Cambodian refugees with premigration histories of trauma received an average of 16 sessions of individual therapy from a Cambodian bicultural counselor at a trauma treatment center in Sydney, Australia. Nineteen of the 20 patients reported that during treatment they had been willing to talk about their trauma histories, a finding that raises doubts about the commonly held belief that Asians are not psychologically minded and avoid disclosing emotionally sensitive information to health care workers. However, self-disclosing therapy alone did not appear to benefit these patients. Only four patients found talking about their trauma story directly helpful in improving their emotional state, and three of the four found the relief to be transitory.

Type A personality in Australian twins.

We examined the genetic and environmental determinants of Type A behavior in 200 pairs of same-sex twins as measured by the structured interview (SI) of Rosenman and Friedman and by the Bortner questionnaire (BARS). As noted previously, these measures are poorly correlated (r = .30). Quite different heritabilities were found for the two measures (63% for SI, 23% for BARS), and the correlation between the two was found to be largely genetic. Although the sample size meant that differences in correlation between MZ and DZ twins on the BARS were not significant in univariate analyses, they were suggestive of twin competition effects, as other twin studies have found. We conclude that further genetic analyses should concentrate on component behaviors rather than the overall Type A construct.

Mood disorders among mothers of infants admitted to a mothercraft hospital.

The mothers (n = 100) of consecutive infants admitted to a mothercraft residential facility were asked to complete the Edinburgh Postnatal Depression Scale (EPDS). Only one of the women had been identified prior to the infant's admission as having postnatal depression, but 39% scored above the cut-off point for likely major depressive disorder. No specific infant problem correlated significantly with a higher depression score. The extent of serious mood disorders in the post-partum population has remained generally unacknowledged despite an upsurge of recent research activity in the field. Nevertheless, this problem has considerable public health significance, impinging as it does on the health of all members of the family. Possible screening and intervention strategies are discussed.

Adults who feared school: is early separation anxiety specific to the pathogenesis of panic disorder?

Although juvenile separation anxiety disorder is maintained to be a predisposing factor to adult panic disorder in DSM-III-R, past research has failed to clarify (a) whether it is separation anxiety per se or school refusal that is the pathogenic risk factor and (b) whether affected youngsters are specifically at risk of developing panic disorder rather than symptoms of general anxiety or phobias in later life. The present study of 74 adults who responded to media publicity found that a measure of early separation anxiety but not a history of school refusal was associated with risk of adult panic disorder according to DSM-III-R criteria. In contrast, separation anxiety scores were not associated with the presence or absence of general anxiety symptoms or phobic-avoidance in adulthood. Subjects with higher separation anxiety scores were more likely to have either a sibling or child with school refusal. Although the present study is limited in its method to mailed survey responses and, in part, to retrospective data, the results do provide additional support for Klein's influential separation anxiety theory of panic disorder.
