“…However, the results correspond with previous findings which showed an influence of contextual variables on the perception of dyspnea [34]. In this regard, de Peuter et al [35] coupled dyspnea, induced by inhalation of CO 2 , with specifically labelled aerosols during training trials. In the following presentation of the labelled aerosols, which were then completely free of CO 2 , healthy and asthmatic participants reported more respiratory symptoms than during presentation of aerosols which have not been coupled with CO 2 inhalation during the preceding training trials.…”

Background:Recent research has shown that distinct dimensions in the perception of dyspnea can be differentiated; however, most studies to date have only used a global rating scale for the measurement of this sensation. Objectives: This study examined the different influence of sensory and affective aspects of perceived dyspnea on the commonly used Borg scale, which measures the global perception of dyspnea. Methods: Dyspnea was induced in 16 healthy volunteers (mean age 26.2 ± 6.3 years) by breathing through an inspiratory resistive load (3.57 kPa/l/s) in two experimental conditions (attention and distraction). After each of the two conditions the experienced intensity (i.e., sensory dimension) and unpleasantness (i.e., affective dimension) of dyspnea were rated on separate visual analog scales (VAS), followed by a global rating of dyspnea on the Borg scale. Hierarchical multiple linear regression models were calculated to analyze the predictive validity of VAS ratings of intensity and unpleasantness on the Borg scale ratings. Results: When subjects attended to their breathing, only VAS intensity scores showed a significant influence on Borg scale ratings (p < 0.05). In contrast, only the VAS unpleasantness scores showed a significant influence on Borg scale ratings (p < 0.05) when subjects were distracted. Conclusions: These findings show that sensory and affective aspects of perceived dyspnea differentially influence the global measure of dyspnea as determined by the Borg scale. A differentiation between these aspects in future studies through the use of separate rating scales could yield more detailed information on the perception and report of dyspnea.

“…In 2005, De Peuter et al (25) stated that overestimation of symptoms is associated with excessive use of medication and need for hospitalization. In 2008, Chapman et al (22) reported that patients who did not require urgent or specialist care were more likely to report shortterm symptom control of asthma than were those who required one or more emergency room visits.…”

Objective: To compare the subjective perception of asthma control reported by the patient with that measured by the score obtained on the Asthma Control Questionnaire 6-item version (ACQ-6) in patients with severe asthma and to determine whether asthma control is associated with the number of emergency room visits in the previous month. Methods: This was a cross-sectional study involving 528 patients treated at the Bahia State Asthma and Allergic Rhinitis Control Program Central Referral Clinic between August of 2008 and March of 2010, in the city of Salvador, Brazil. The patients completed the ACQ-6 and answered a specific additional question in order to evaluate their own perception of asthma control in the previous week. Results: We evaluated 423 patients who met the inclusion criteria. The sample was predominantly female (81.3%), and 64.3% had an income lower than two times the national minimum wage. The mean age was 49.85 ± 13.71 years, and the duration of asthma symptoms was 32.11 ± 16.35 years. The patients had been regularly treated via the program for 36.65 ± 18.10 months. Based on the subjective perception of asthma control, only 8% of the patients considered their asthma to be uncontrolled, whereas 38.8% had an ACQ-6 score ≥ 1.5, which indicates poor control. The kappa statistic revealed poor concordance between the two methods. There was a direct association between uncontrolled asthma and the number of emergency room visits in the previous month (p < 0.001). Conclusions: In this sample of patients, the subjective perception of asthma control differed from that measured by the ACQ-6 score, and the patients overestimated their own level of asthma control, which puts them at risk of being undertreated.Keywords: Asthma; Health services; Questionnaires. ResumoObjetivo: Comparar a percepção subjetiva do controle da asma informada pelo paciente com aquela obtida por meio do escore do Asthma Control Questionnaire com seis questões (ACQ-6) em pacientes com asma grave e verificar se o controle da asma está associado ao número de visitas a salas de emergência no mês anterior. Métodos: Estudo transversal de 528 pacientes acompanhados na Central de Referência do Programa para Controle da Asma e Rinite Alérgica na Bahia, entre agosto de 2008 e março de 2010, em Salvador (BA). Os pacientes responderam ao ACQ-6 e a uma questão adicional específica para avaliar sua percepção do controle da doença na semana prévia. Resultados: Foram avaliados 423 pacientes, que preencheram os critérios de inclusão. A maioria era do gênero feminino (81,3%) e possuía renda familiar menor que dois salários mínimos (64,3%). A média de idade foi de 49,85 ± 13,71 anos, e a duração dos sintomas de asma foi de 32,11 ± 16,35 anos. Os pacientes eram regularmente tratados no programa há 36,65 ± 18,10 meses. Baseados na percepção subjetiva do controle, 8% dos pacientes consideraram a sua asma não controlada, enquanto 38,8% obtiveram escore do ACQ ≥ 1,5, indicando falta de controle. O coeficiente kappa revelou fraca concordância entre os ...

“…This perception is modulated by past experience: the brain seems to memorize the level and the characteristics/quality of dyspnea induced by a previous activity, effort, or situation, to set the expectations accordingly, and ultimately compare the current input with that in the past [52,53]. It has been shown that, following conditioning, even harmless cues per se may trigger dyspnea with varying susceptibilities in different groups of individuals [54]. This reference is subject to changes at the conscious level using cognitive processes such as experience, learning, and interpretation [16,39,51].…”

“…Previous experience and learning are two of the key factors influencing dyspnea [51,54]. Another one is negative affectivity, i.e., the general tendency to experience negative emotions and self-image, introversion, and dwelling on failures and shortcomings.…”
