Variations in therapeutic interventions for Cambodian and Chilean refugee survivors of torture and trauma: a pilot study.

The treatment of refugee survivors of torture and trauma has attracted increasing clinical attention. The present study surveyed therapists concerning the emphasis that was placed on disclosure of previous traumatic experiences in therapy with refugees from Chile and Cambodia. Significant differences were found between the two groups with trauma story discussion being judged by therapists to be more important to treatment outcome in Chilean patients. The problem of potential therapist bias limits definitive conclusions, however we suggest that differences in cultural preparedness for psychotherapy aimed at uncovering previous traumatic experiences may be the main reason for variations in styles of therapy offered to these distinctive ethnic groups. Other possible explanations are differences in diagnostic profiles and types of previous traumatic experiences.

The development of the Separation Anxiety Symptom Inventory (SASI).

Separation anxiety continues to be implicated as an early risk factor to adult emotional disorder but recent research findings are somewhat contradictory. Inconsistencies in approaches to measuring memories of early separation anxiety may have contributed to this lack of clarity. We report the development of a brief self-report instrument, the Separation Anxiety Symptom Inventory (SASI), which was designed to overcome some of these deficiencies in measurement. The SASI was shown to have a coherent factorial structure, high internal consistency (Cronbach's Alpha > .80) and test-retest reliability over an average of 24 months (Intraclass Correlation Coefficient = .89), with serial scores not being affected by changes in contemporaneous anxiety levels. Some index of the validity of the measure was achieved by (a) comparing SASI scores of index twins with descriptors of their "insecure" behaviours in early life provided by corresponding co-twins; (b) comparing SASI scores with retrospective DSM III-R diagnoses of early anxiety disorders obtained by structured interviews; and (c) examining SASI scores in subjects with histories of school refusal. The SASI provides a useful standardised measure which will aid in the further testing of the separation anxiety hypothesis of adult emotional disorder.

Reported early separation anxiety symptoms in patients with panic and generalised anxiety disorders.

Attachment theory has proposed that early separation anxiety is a risk factor for adult anxiety disorder, with the recent focus being particularly on panic disorder. The results of empirical studies examining this link are, however, contradictory, possibly because of inconsistencies across studies in measuring memories of early separation anxiety. In the present study, a psychometrically sound measure, the Separation Anxiety Symptom Inventory (SASI) was used to compare memories of such early symptoms in panic disorder (including those with mild phobic-avoidance), generalised anxiety disorder and control subjects. Anxiety patients as a group returned higher SASI scores (p < 0.001) with a non-significant trend for panic disorder patients to score higher than those with generalised anxiety. These results suggest that early separation anxiety may be a harbinger of adult anxiety and that risk of panic disorder may be higher in the most severely affected youngsters. As a risk factor, early separation anxiety does not however appear to be uniquely related to adult panic disorder.

Risk of retraumatisation of asylum-seekers in Australia.

Australia has a long legacy of providing asylum to refugees who, it is now well established, suffer high rates of psychological and psychiatric problems requiring specialised treatment. In this paper we outline the special stressors faced by asylum-seekers who have not obtained formal refugee status and who are at risk of being forcibly repatriated. We suggest that the experiences they undergo in Australia, particularly that of prolonged detention, risk retraumatising an already vulnerable group. The implications for policy formulation are considered.

Do sex-linked behaviors in children influence relationships with their parents?

When relationships are found between parents' and children's behaviors it is usually assumed the parents' behaviors produced those of the children. Forty-four young adult males and 36 young adult females reported the degree to which they showed various sex-linked behaviors and feelings of same versus opposite sex identity in childhood, and adolescence, and currently. These behaviors accounted for up to 57% of the variance of measures of the quality of relationships with parents. In men, opposite-sex-linked behaviors and identity correlated most strongly with current negative parental and particularly paternal relationships. They also correlated strongly with negative paternal relationships in childhood. Some sex-linked behaviors and sex identity items in men correlated positively with maternal overprotection in childhood and adolescence. Correlations between women's sex-linked behaviors and sexual identity items and their parental relationships were weaker but more consistently negative. As in men, opposite-sex-linked behaviors and identity in women correlated most strongly with current negative paternal relationships. The pattern of the associations and the finding that many opposite-sex-linked behaviors in subjects' childhood correlated most strongly with negative parental relationships in early adult life suggest that the parents' feelings could be partly a response to, rather than totally causal of, the subjects' sex-linked behaviors.

Cultural influences in psychotherapy with refugee survivors of torture and trauma.

A selective review of the literature describing treatment of refugee survivors of torture and trauma revealed that approaches to psychotherapy used in treating South American patients differed from those used in treating Indochinese patients. South American patients were receptive to psychodynamic psychotherapeutic approaches that focused on detailed recollection of past trauma. Indochinese patients responded to a broader-based rehabilitation approach that could include psychotropic medication, supportive psychotherapy, and assistance in meeting practical needs. The authors suggest that many of the differences in treatment of the two groups may be attributed to cultural factors, with South American patients reflecting an affinity for the Western philosophical assumptions in which psychodynamic therapy is rooted and Indochinese patients reflecting a cultural background that values responsibility to the group, deference to authority, and restrained modes of emotional expression.

Parental representations of patients with panic disorder and generalised anxiety disorder.

Previous studies using the Parental Bonding Instrument have shown a general trend for neurotic subjects to score their parents as less caring and more protective. Such a finding was broadly replicated in a study of 80 clinically anxious subjects and age- and sex-matched controls. Although direct comparisons of PBI scores failed to reveal clear-cut differences between generalised anxiety (GA) and panic disorder (PD) subgroups, logistic regression analyses revealed higher odds ratios for parental assignment to aberrant categories in the GA group, with PD patients reporting a more limited pattern of overprotective parenting only. Our findings suggest that adverse parental behaviour may be relevant to the pathogenesis of GA, while parental 'affectionate constraint' may be a parental response to early manifestations of PD.

Psychosocial needs of torture survivors.

Growing recognition that the world faces a modern epidemic of torture has stimulated widespread interest amongst mental health professionals in strategies for the treatment of survivors. In this article we outline the distinctive experiences of torture survivors who present for treatment in western countries. These survivors are usually refugees who, in addition to torture, have suffered a sequence of traumatic experiences and face ongoing linguistic, occupational, financial, educational and cultural obstacles in their country of resettlement. Their multiple needs call into question whether "working through" their trauma stories in psychotherapy will on its own ensure successful psychosocial rehabilitation. Drawing on our experience at a recently established service, we propose a broader therapeutic aim.

Opposite sex behaviours correlate with degree of homosexual feelings in the predominantly heterosexual.

There is extensive evidence that subjects who identify as homosexual show opposite sex-linked behaviours. However no attempt has been made to investigate whether a similar association exists between such behaviours and the presence of homosexual feelings in the predominantly heterosexual. Eighty medical students completed an anonymous questionnaire reporting the ratio of their heterosexual to homosexual feelings and the presence of sex-linked behaviours in their earlier life and currently. As in previous studies correlations between opposite sex behaviours and subjects' degree of homosexual feelings were found in the male subjects. Correlations remained present, though mainly at a weaker level, in the predominantly heterosexual students. It is suggested this evidence of a dimensional relationship between opposite sex-linked behaviours in childhood and degree of homosexual feeling in adulthood renders irrational the classification of such behaviours as a gender identity disorder of childhood when homosexuality in adults is not regarded as a disorder.

Doctors and the state: lessons from the Biko case.

The death of the well-known black leader, Steve Biko, in detention in South Africa in 1977 has continued to generate debate in the international medical literature. The three doctors who examined him during his terminal illness made a diagnosis of malingering in spite of overwhelming evidence suggesting that he had suffered extensive traumatic brain injury while in detention. The inquest into his death provided a rare insight into the manner in which state doctors function in relation to the police of a repressive regime. This article documents the relevant testimony from the inquest and explores the reasons for the doctor's mismanagement of Biko. It is suggested that failures in the doctors' judgement were a result of complex influences including the effects of their own social conditioning, the risk of habituation by state doctors to degrading prison conditions, the inroads that Apartheid has made into medical practice, the possibility of reprisal if state doctors oppose the wishes of the police, and, more speculatively, the possibility that the doctors' obedience and passivity were exploited by the Security Police who wished to absolve themselves from responsibility of Biko's injuries. Most importantly, it is argued that the repeated failure of the major medical organizations in South Africa to provide clear guidance and leadership to state-employed doctors increases the risk that individual doctors will continue to succumb to hierarchical pressures to condone acts of state-sanctioned violence against detainees.

Perceptions of general and specific therapist behaviors.

In the process of developing a two-part therapist rating scale, we obtained questionnaire responses from a large sample of subjects who had undergone one of a variety of psychotherapies. Our data support the importance of perceived therapist care as a strong correlate of patient satisfaction, and patients seemed able to discriminate clearly between psychodynamic and cognitive-behavioral therapies. In the first (nonspecific) questionnaire, we derived five dimensions (Care-Concern, Directive-Control, Critical-Confronting, Understanding, and Charisma) from principal-components analyses, with the first two dimensions being relatively independent of each other. A multiple-regression analysis revealed that combined scale scores accounted for 50% of the variance of patient satisfaction ratings, with the Care dimension accounting for most of this effect. In the second questionnaire, data were analyzed from respondents who had undergone therapy with known cognitive-behavioral or psychodynamic therapists; but, in a minority of subjects who were recruited through the media, we depended on detailed descriptive vignettes to allocate them to one or another of these "specific" types of psychotherapy. Six scales emerged, three characterizing cognitive-behavioral therapies (Behavioral Task Orientation, Organization, and Cognitive Focus) and three representing psychodynamic therapies (Transference, Inner Conflict, and Relationship). Subjects' ratings on all scales strongly discriminated between the two broad modalities of therapy, suggesting that patient reports may provide valid measures of therapist styles. We conclude that questionnaires such as the one we are developing may provide economical measures for assessing therapist consistency when comparing different modalities of psychotherapy.

Biologism in psychiatry.

A recent study visit to North America impressed on me the seriousness with which Australian psychiatry should consider the recent ideological shift in the USA to an extreme biological model of mental disorders. There is increasing evidence that proponents of this model are not simply promoting the value of biological research (with which few psychiatrists would quibble), but that the field is at risk of being overwhelmed by a reductionistic "biologism" which assumes an organic causation for all abnormal human behaviour.

The development of the New South Wales Service for the Treatment and Rehabilitation of Torture and Trauma Survivors (STARTTS): the first year.

Many immigrants to Australia are refugees, some of whom have experienced acute stress and trauma, including torture, prior to or during their escape from their home countries. In response to a growing recognition that the health care services may not be meeting the needs of these people the NSW Department of Health funded the establishment of a community-based rehabilitation service for traumatised refugees. This paper provides an overview of the recent history of the service, some of the organisational and staffing issues faced during its first year, some characteristics of the first 200 clients, principles of treatment, clinical, nosological and therapeutic issues and relationships with other agencies.

Counselling survivors of torture and refugee trauma.

A substantial number of refugees arriving in Australia are the victims of torture and other forms of organised violence. In this article, the authors provide an overview of the broad range of physical and emotional disabilities that arise from these experiences, examine the special difficulties in identifying and assessing patients at the primary health care level, and offer an approach to counselling for survivors and their families.

Behaviour completion mechanisms, anxiety and agoraphobia.

Little attention has been paid to the situations which provoke the initial attack of anxiety in agoraphobia. According to the behaviour completion hypothesis many normal subjects experience increased tension in such situations when there is a delay in the completion of a behaviour. One hundred and eight medical students completed a questionnaire designed to investigate this hypothesis. They reported experiencing increased tension or anxiety significantly more frequently in situations provoking agoraphobia when the situations contained a component of delay, as compared to such situations without this component, or to situations not commonly provoking agoraphobia. It is proposed that tension, anxiety and panic form a continuum of increasing levels of arousal, but are associated with different cognitions. It is further proposed that the arousal level of agoraphobics is sensitized, so that delay which provokes mild increases of arousal in the healthy, provokes high arousal in agoraphobics. This finding supports the hypothesis that delay in behaviour completion is a mechanism in the generation of tension and anxiety.

A family panics.

We report the treatment of a family in which both spouses developed panic disorder, and their son, school phobia, soon after the death of a close relative. The interactional style observed within this family suggested that interpersonal factors were important in the generation of anxiety in each member. Detailed case histories such as the one we report underscore the importance of a systemic perspective when assessing individuals who present with anxiety disorders.

Lifestyle factors in monozygotic and dizygotic twins.

In examining genetic influences on biological variables using twins, it may be important to examine the distribution between and within twin pairs of demographic and lifestyle factors that may themselves affect the biological variable being studied. We explored the distribution of demographic and lifestyle factors that may affect blood lipid levels or ischaemic heart disease (IHD) risk among a sample of 106 monozygotic (MZ) and 94 like-sex dizygotic (DZ) twin pairs. In our sample, MZ twins were statistically significantly different from DZ twins only in marital status, cigarette smoking habits, and the ratio of polyunsaturated to saturated fat (P:S ratio) in their dietary intake. The latter variable was among many dietary variables examined (using 4-day weighed food diaries), and the size of the difference in intake was small. When comparisons were made of the similarities within twin pairs, we found members of MZ twin pairs to be statistically significantly closer than DZ twins in educational achievement, occupation, cigarette smoking, and exercise habits, and the number of days a week on which alcohol was consumed. These last three variables were consistently closer among twins with closer contact than among those with a smaller degree of current shared environment. For 12 of the 13 nutrients examined, the within-pair correlations were higher for MZ than for DZ twins, although our test for significant genetic variance showed statistical significance only for intake of complex carbohydrates. We conclude that MZ twins share demographic and lifestyle factors that might influence the risk of IHD and blood lipid levels to a greater degree than do DZ twins, although it is difficult to say if these similarities in lifestyle result from genetic influences or not. Nevertheless, ascribing differences between correlations in MZ and DZ twin pairs for lipid levels as being purely "genetic"--as implicit in conventional measures of heritability--is likely to overestimate the influence of genetic factors.
