Treatment outcome in individuals with chronic pain: is the Pain Stages of Change Questionnaire (PSOCQ) a useful tool? Jenny StrongCorresponding Author Contact Information, E-mail The Corresponding Author, a, Kym Westburya, Glen Smithb, Ian McKenziec and William Ryan

The efficacy of psychological treatments emphasising a self-management approach to chronic pain has been demonstrated by substantial empirical research. Nevertheless, high drop-out and relapse rates and low or unsuccessful engagement in self-management pain rehabilitation programs have prompted the suggestion that people vary in their readiness to adopt a self-management approach to their pain. The Pain Stages of Change Questionnaire (PSOCQ) was developed to assess a patient's readiness to adopt a self-management approach to their chronic pain. Preliminary evidence has supported the PSOCQ's psychometric properties. The current study was designed to further examine the psychometric properties of the PSOCQ, including its reliability, factorial structure and predictive validity. A total of 107 patients with an average age of 36.2 years (SD = 10.63) attending a multi-disciplinary pain management program completed the PSOCQ, the Pain Self-Efficacy Questionnaire (PSEQ) and the West Haven-Yale Multidimensional Pain Inventory (WHYMPI) pre-admission and at discharge from the program. Initial data analysis found inadequate internal consistencies of the precontemplation and action scales of the PSOCQ and a high correlation (r = 0.66, P < 0.01) between the action and maintenance scales. Principal component analysis supported a two-factor structure: 'Contemplation' and 'Engagement'. Subsequent analyses revealed that the PSEQ was a better predictor of treatment outcome than the PSOCQ scales. Discussion centres upon the utility of the PSOCQ in a clinical pain setting in light of the above findings, and a need for further research. (C) 2002 International Association for the Study of Pain.

An evaluation of a family psychoeducation program in community mental health

The aim of the research project was to identify the efficacy of the family psychoeducation program as a strategy for reducing the hospital admissions of young people. It also aimed to determine if the family psychoeducation program had an impact on the experience of caregiving and knowledge and satisfaction of services provided by the mental health service. A retrospective chart audit compared readmission history of 27 clients whose families attended a psychoeducation program with readmission history of a matched group of young people whose families did not attend the program. A telephone survey was conducted for both groups of families to investigate knowledge and understanding of services and burden of care. The results indicated that family participation in a brief multiple family psychoeducation program did not reduce the number or duration of admissions of the young people. There was no impact on the level of care for families who attended the psychoeducation program, however, this group showed some evidence of increased knowledge and understanding of services as compared to the control group.

Synonymy of Boophilus Curtice, 1891 with Rhipicephalus Koch, 1844 (Acari : Ixodidae)

Recent molecular and morphological studies of the genera Rhipicephalus Koch, 1844 and Boophilus Curtice, 1891 revealed that the five species of Boophilus make the genus Rhipicephalus paraphyletic. Thus, Rhipicephalus Koch, 1844 is not a monophyletic ( natural) lineage and some species of Rhipicephalus are more closely related to the species of Boophilus than to other species of Rhipicephalus. Here, we revise these genera: Boophilus is synonymised with Rhipicephalus, and Rhipicephalus ( sensu lato) ( including Boophilus) is redefined. By synonymising Boophilus with Rhipicephalus, we have changed the nomenclature so that it reflects our understanding of the phylogeny of these ticks. Boophilus is retained as a subgenus of Rhipicephalus, so the synonymy of Boophilus with Rhipicephalus does not result in the loss of the name Boophilus. In addition, Rhipicephalus is a well- known genus and the change proposed is simple - all five species of Boophilus become members of Rhipicephalus ( Boophilus).

Independent contribution of plaque complexity to myocardial ischemia during Dobutamine stress echocardiography

The influence of complex plaque morphology on the extent of demand-induced ischemia in unselected patients is not well defined. We sought to investigate the functional significance of lesion morphology in patients who underwent coronary angiography and dobutamine stress echocardiography (DSE).,Angiography and DSE were performed within a 6-month period (mean 1 +/- 1 month) in 196 patients. Angiographic assessments involved quantification of stenosis severity, assessment of the extent of jeopardized myocardium, and categorization of plaque morphology according to the Ambrose classification. DSE was interpreted by separate investigators with respect to wall motion score index (WMSI) and number of coronary territories involved. A general linear model was constructed to assess,the independent contribution of patient characteristics and angiographic and DSE results with respect to extent of ischemic myocardium. Complex lesion morphology was seen in 62 patients (32%). Patients with complex lesions were more likely to have had prior myocardial infarction (p < 0.001) and be current smokers (p = 0.03). During angiography, they exhibited a trend toward a greater number of diseased vessels, had a greater coronary jeopardy score (p < 0.001) and more frequent collateral flow (p = 0.03). During echocardiography, patients had a higher stress WMSI (p < 0.001) and were more likely to show ischemia in all 3 arterial territories (p < 0.01). On multivariate regression, the coronary artery jeopardy score and the presence of complex plaque morphology were independent predictors of the extent of ischemic myocardium (R 2 = 34%, p < 0.001). Thus, patients with complex plaque morphology are older, more likely to smoke, and more likely to have had prior myocardial. infarction. They exhibit more extensive disease with higher coronary jeopardy scores and a higher resting and peak stress WMSI. Despite these differences, complex plaque morphology remains an independent predictor of the extent of ischemia during stress. (C) 2003 by Excerpta Medica, Inc.

Preferência de Cotesia flavipes (Cameron, 1891) (Hymenoptera: Braconidae) por lagartas de Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) alimentadas com diferentes cultivares de cana-de-açúcar

O objetivo desta pesquisa foi avaliar a preferência do parasitoide Cotesia flavipes (Hymenoptera: Braconidae) por lagartas de Diatraea saccharalis (Lepidoptera: Crambidae), alimentadas com diferentes cultivares de cana-de-açúcar. O experimento foi conduzido em laboratório, em duas condições de alimentação, uma envolvendo lagartas de D. saccharalis, alimentadas em dieta artificial, e, a outra, com lagartas alimentadas em dieta artificial e mantidas temporariamente nos toletes dos cultivares de cana-de-açúcar. Os cultivares utilizados foram: SP80-1842 e SP81-3250, resistentes, e RB855536, suscetível à D. saccharalis. A preferência para oviposição das fêmeas de C. flavipes foi avaliada em testes com e sem chance de escolha, em delineamento inteiramente casualizado, com quatro tratamentos e 15 repetições. Lagartas de D. saccharalis com 19 dias de idade foram oferecidas para fêmeas de C. flavipes, acasaladas e com 24 horas de idade, em ambos os testes. No teste com chance de escolha, utilizou-se um olfatômetro, o qual constou de quatro compartimentos, em cujo centro liberaram-se quatro fêmeas de C. flavipes, enquanto, no teste sem chance de escolha, foram utilizadas placas de Petri, no interior das quais se colocou uma lagarta de D. saccharalis, oriunda das duas condições de alimentação. Nestes testes, foi observada a percentagem de parasitismo e, continua-mente, o comportamento da primeira escolha de fêmeas de C. flavipes, em intervalos de zero a um, um a três, três a cinco, cinco a oito e de oito a dez minutos após as liberações. Lagartas de D. saccharalis, oriundas da alimentação em dieta artificial com colmos triturados dos cultivares, foram igualmente preferidas para atratividade de fêmeas do parasitoide C. flavipes. A percentagem de parasitismo de lagartas de D. saccharalis, criadas com dietas artificiais com colmos dos cultivares SP80-1042 e RB855536, foi igualmente parasitadas por C. flavipes.
