Smoking behaviors across anxiety disorders.

The purpose of this study was to test the theory put forth by Zvolensky et al. [Clin. Psychol. Sci. Pract. 10 (2003) 29] that smoking is specifically associated with panic disorder (PD) and not more generally associated with other anxiety disorders. Smoking behaviors were examined across three anxiety disorders: panic disorder with or without agoraphobia, social phobia (SP), and obsessive-compulsive disorder (OCD). A greater proportion of the PD group (40.4%) reported smoking compared to the SP (20%) and OCD (22.4%) groups. Those in the PD group were also more likely than those in the other groups to report being a heavy smoker (greater than 10 cigarettes daily). No significant interaction between diagnosis and smoking status was found for any of the symptom measures. However, participants who smoked had significantly higher scores than nonsmokers on a number of scales, including measures of depression, general anxiety, and distress. Differences in anxiety sensitivity between smokers and nonsmokers approached significance. These findings provide support for Zvolensky et al.'s [Clin. Psychol. Sci. Pract. 10 (2003) 29] theoretical conceptualization and suggest a specific link between smoking and panic disorder. Further investigation is warranted to determine the causal direction of this association.

Obsessive-compulsive spectrum conditions in obsessive-compulsive disorder and other anxiety disorders.

In light of current interest in an obsessive-compulsive spectrum of disorders, this study sought to determine whether comorbidity patterns support the unique relationship hypothesized between these conditions and obsessive-compulsive disorder (OCD). Comparisons were made of lifetime rates of several proposed spectrum conditions in individuals with one of three anxiety disorder principal diagnoses (OCD, social phobia, or panic disorder [PD], N=277). Spectrum conditions examined included tic-related disorders, trichotillomania, skin picking, and eating disorders, with analyses performed on rates both of clinical disorder alone, and clinical and subclinical manifestations jointly. The OCD group was found to differ from both other groups in showing 1) a greater proportion of individuals affected with any lifetime spectrum condition, 2) a greater number of lifetime spectrum conditions affecting each individual, and 3) a greater proportion of individuals having a lifetime history of multiple spectrum conditions. Analyses for specific spectrum conditions indicated differences among the anxiety disorder groups for all spectrum categories except eating disorders, though only in the case of tic-related conditions did OCD differ significantly from both comparison groups. For the other conditions, dissimilar patterns of differences were observed among the three groups, particularly when subclinical manifestations were included. These findings have conceptual and clinical implications, including 1) the salience of tic-related disorders in the OC spectrum, 2) the possibility that the relationship between spectrum conditions and anxiety disorders may take several different forms, and 3) the need for refinement of the hypothesized spectrum.

Measuring outcomes in aesthetic surgery: a comprehensive review of the literature.

Outcomes research examines the end results of medical interventions, taking into account patients' experiences, preferences, and values. The purpose of assessing outcomes is to provide evidence on which to base clinical decisions. The assessment of outcomes in aesthetic surgery is especially pertinent because patient satisfaction is the predominant factor in determining success. In cosmetic surgery, various scales have been used to assess outcomes. Unfortunately, none of these methods has achieved widespread use. The adoption of broadly accepted, relevant scales to measure outcomes would be advantageous, because this would allow the comparison of techniques, quantification of positive effects, and identification of patients unlikely to benefit from surgery. The purpose of this study was to critically review the present literature to identify the appropriate instruments to assess outcomes in aesthetic surgery. After a comprehensive review of aesthetic surgery outcome instruments, the authors identified body-image and quality-of-life measures to be of the greatest value in determining aesthetic surgery outcomes. These conclusions were based on a critical evaluation of the feasibility, validity, reliability, and sensitivity to change of these measures. The Multidimensional Body-States Relations Questionnaire (MBSRQ), a psychological assessment of body image, was selected as a potential candidate for further study. Two additional body-image assessment instruments, the Facial Appearance Sorting Test (FAST) and the Breast Chest Ratings Scale (BCRS), may be useful in the assessment of rhinoplasty and breast surgery, respectively. The Derriford Scale (DAS59), an instrument that assesses appearance-related quality of life, was also selected. In addition, the authors recommend the use of a generic, utility-based quality-of-life instrument, such as the Health Utilities Index (HUI) or the EuroQol (EQ-5D).

Competency assessment in the McMaster Psychotherapy Program.

In January 2001 the Residency Review Committee (RRC) mandated that all psychiatric training programs must demonstrate competency in five forms of psychotherapy. Assessing competency in psychotherapy is a complex and difficult task, with many conceptual and practical issues needing consideration before programs are implemented. Existing competency-based programs can offer some assistance to institutions struggling with this issue. This paper discusses competency assessment in the McMaster Psychotherapy Program, paying special attention to instruments used in the evaluation process. Preliminary results with respect to resident satisfaction with the Program and resident competency in certain therapies are also discussed.

Responses to panic induction procedures in subjects with multiple chemical sensitivity/idiopathic environmental intolerance: understanding the relationship with panic disorder.

Idiopathic environmental intolerance (IEI), also known as multiple chemical sensitivity, is a clinical description for a cluster of symptoms of unknown etiology that have been attributed by patients to multiple environmental exposures when other medical explanations have been excluded. Because allergy has not been clearly demonstrated and current toxicological paradigms for exposure-symptom relationships do not readily accommodate IEI, psychogenic theories have been the focus of a number of investigations. A significantly higher lifetime prevalence of major depression, mood disorders, anxiety disorders, and somatization disorder has been reported among patients with environmental illness compared with that in controls. Symptoms often include anxiety, lightheadedness, impaired mentation, poor coordination, breathlessness (without wheezing), tremor, and abdominal discomfort. Responses to intravenous sodium lactate challenge or single-breath inhalation of 35% carbon dioxide versus a similar breath inhalation of clean air have shown a greater frequency of panic responses in subjects with IEI than in control subjects, although such responses did not occur in all subjects. Preliminary genetic findings suggest an increased frequency of a common genotype with panic disorder patients. The panic responses in a significant proportion of IEI patients opens a therapeutic window of opportunity. Patients in whom panic responses may at least be a contributing factor to their symptoms might be responsive to intervention with psychotherapy to enable their desensitization or deconditioning of responses to odors and other triggers, and/or may be helped by anxiolytic medications, relaxation training, and counseling for stress management.
