Utilizing this principle, exposure in vivo seems an effective treatment for many, but not all, obsessional patients. The role of tricyclic drugs is at present being investigated. Nurse therapists have been found to be very competent in delivering treatment. Similar results, using an exposure in vivo model, have been obtained in the managment of phobias. Some reasons why patients do not comply with, or adhere to, treatment recommendations are put foward. Finally, the vexed question of the cost-effectiveness of treatment is considered.

There are good grounds for including these cases within the diagnostic concepts of OCD, with significant implications for clinical management. Aims To present cases with unusual OCD, in order to re-evaluate the issue of delusions and OCD. Method The cases of five subjects with delusions in the course of obsessive–compulsive disorder are presented to illustrate ‘delusional’ OCD. The management and outcome of these cases are discussed. Results Fixity and bizarreness of beliefs in OCD occur on a continuum from ‘none’ to ‘delusional intensity’ and may fluctuate within subjects. Conclusions The idea that these cases may represent a form of OCD has implications for management, as, if this is correct, they should be able to respond to appropriat...

No comparison has previously been made of specialist versus general psychiatric in-patient care. METHOD During a randomised study of cue exposure, 186 opiate addicts were also randomised to either specialist in-patient (DDU; n = 115) or general psychiatric (GEN; n = 71) wards in the same hospital. RESULTS From pre-treatment (post-randomisation) onwards, patient outcomes differed across the two in-patient settings. Of the original randomised sample, significantly more DDU than GEN subjects accepted their randomisation (100 v. 77%), were subsequently admitted (60 v. 42%), and completed in-patient detoxification (45 v. 18%). Of patients admitted, more DDU than GEN patients completed detoxification (75 v. 43%). During seven-month follow-up, of those 43 patients who reached the end of treatment, significantly more ex-DDU than ex-GEN subjects were opi...

Normal anxiety is an emotion that helps organisms defend against a wide variety of threats. There is a general capacity for normal defensive arousal, and subtypes of normal anxiety protect against particular kinds of threats. These normal subtypes correspond somewhat to mild forms of various anxiety disorders. Anxiety disorders arise from dysregulation of normal defensive responses, raising the possibility of a hypophobic disorder (too little anxiety). If a drug were discovered that abolished all defensive anxiety, it could do harm as well as good. Factors that have shaped anxiety-regulation mechanisms can explain prepotent and prepared tendencies to associate anxiety more quickly with certain cues than with others. These tendencies lead to excess fear of largely archaic dangers, like snakes, and too little fear of new threats, like cars. An understanding of the evolutionary origins, functions, and mechanisms of anxiety suggests new questions about anxiety disorders.

It is therefore important to examine what factors influence treatment outcome. However, other than type of treatment received, relatively little is known about what predicts outcome. 2-4 Meta-analyses of the natural development of PTSD following trauma identify poorer social support as the predictor with the greatest weighted effect size. 5,6 However, no research has directly examined whether social support also predicts treatment response. Social support as a putative predictor of treatment outcome merits research attention as it is directly amenable to social and (or) clinical intervention.

Patients with SMI were randomised to have hospital care or be looked after by a community psychiatric care team in a Daily Living Programme (DIP). The day-to-day work of a clinical team with the difficulties encountered in delivering community psychiatric care in an inner city is described. There were seven deaths from self-harm during the 45-month study. One DIP patient committed homicide. An ordeal by media following this and the suicides are described. Lessons learnt include the need for the community care team to be responsible for discharge from any in-patient phases and for attention to team morale, especially during adversity, and to time spent working under pressure.

The objective of this study was to examine whether trained lay counselors can carry out effective treatment of posttraumatic stress disorder (PTSD) in a refugee settlement. In a randomized controlled dissemination trial in Uganda with 277 Rwandan and Somalian refugees who were diagnosed with PTSD the authors investigated the effectiveness of psychotherapy administered by lay counselors. Strictly manualized narrative exposure therapy (NET) was compared with more flexible trauma counseling (TC) and a no-treatment monitoring group (MG). Fewer participants (4%) dropped out of NET treatment than TC (21%). Both active treatment groups were statistically and clinically superior to MG on PTSD symptoms and physical health but did not differ from each other. At follow-up, a PTSD diagnosis could not be established anymore in 70% of NET and 65% TC participants, whereas only 37% in MG did not meet PTSD criteria anymore. Short-term psychotherapy carried out by lay counselors with limited training can be effective to treat war-related PTSD in a refugee settlement.

Two patients had cervical spondylosis. The mean age at onset of the fear was 54-thirty years later than that for agoraphobia. Fear of public places and of heights was not prominent, nor was depersonalisation or depression. These "space phobias" might be a hitherto unrecognised syndrome or an unusual variant of agoraphobia. The visuospatial reflexes involved might illuminate the pathogenesis of certain fears.

Three out of four patients treated by implosion (flooding) became almost symptom-free after a mean of 14 sessions and remained so over six-and-a-half months' follow-up. The mechanism of action of the method is not yet clear.

Our study investigated relations between predictor variables and outcome (on the Clinician Administered Posttraumatic Stress Disorder [PTSD] Scale [CAPS]) at posttreatment for 77 treatment completers in a randomized controlled trial of exposure therapy and (or) cognitive restructuring, compared with relaxation, for chronic PTSD in adults. More social support on the Significant Others Scale significantly predicted better outcome on the CAPS, even after controlling for the effects of treatment group and of pretreatment severity. Importantly, social support was only a significant predictor of outcome for participants receiving cognitive restructuring and (or) exposure therapy and not for participants in the relaxation condition. Better social support is associated with significantly greater gain following cognitive restructuring and (or) exposure therapy for PTSD. Future i...

Clinical training programmes have the ultimate aim of improving patients' health, but rarely measure their success in attaining it. This paper provides an analysis of the results of clinical outcome for 2,032 patients treated during eight consecutive English National Board 650 courses, in which 68 nurse behaviour therapist trainees were trained at the Maudsley Hospital from 1978-91. The outcome of 668 patients treated in three recent courses (1987-91) is compared with that of 1,384 patients treated in five earlier courses (1978-86). Measures and diagnostic categories were similar over the whole study period. The trainees in 1987-91 achieved a similar health gain for most of their patients as did their counterparts in 1979-86, but this was achieved over a shorter time spent with each patient, and with great...
