RESUMO
OBJECTIVE: Older adults are at increased risk for depression and poor asthma outcomes. We examined whether depressive symptoms are associated with overperception of airflow obstruction and a pattern of worse asthma control, but not pulmonary function. METHODS: We recruited a cohort of adults with asthma 60 years and older in East Harlem and the Bronx, New York. Baseline measures included the Geriatric Depression Scale, Asthma Control Questionnaire, and Mini Asthma Quality of Life Questionnaire. Spirometry was conducted at baseline to assess pulmonary function. Perception of airflow obstruction was assessed for 6 weeks following baseline by participants entering estimates of peak expiratory flow (PEF) into a programmable peak flow meter followed by PEF blows. Participants were blinded to actual PEF values. The percentage of time that participants were in the overperception zone was calculated as an average. RESULTS: Among the 334 participants (51% Hispanic, 25% Black), depressive symptoms were associated with overperception of airflow obstruction (ß = 0.14, p = .029), worse self-reported asthma control (ß = 0.17, p = .003), and lower asthma-related quality of life (ß = -0.33, p < .001), but not with lung function (ß = -0.01, p = .82). Overperception was also associated with worse self-reported asthma control (ß = 0.14, p = .021), but not lung function (ß = -0.05, p = .41). CONCLUSIONS: Depressive symptoms were associated with greater perceived impairment from asthma, but not pulmonary function. Overperception of asthma symptoms may play a key role in the relationship between depression and asthma outcomes in older adults.

El propósito de esta investigación fue describir y establecer la relación que hay entre las creencias y normas subjetivas con la intención de conducta proambiental en una institución universitaria privada de la ciudad de Bogotá (Colombia). Se contó con la participación de 346 estudiantes seleccionados mediante un muestreo no probabilístico según la proporción de programas de pregrado y posgrado. Se administró la Escala de Comportamiento Proambiental (67 ítems), que evalúa creencias, normas subjetivas e intención de conducta proambiental. Se identificó que las normas subjetivas pro y antiambientales pueden ser predictores consistentes de la intención de conducta pro y antiambiental.
The purpose of this study was to describe and establish the relationship between beliefs and subjective norms with the pro-environmental intention of a private university in the city of Bogota (Colombia). A total of 346 students participated in the study, and they were selected using non-probability sampling according to the proportion of undergraduate and graduate programs. The pro-environmental behaviour scale (67 items) was administered in order to evaluate beliefs, subjective norms, and intention of pro-environmental behaviour. It was found that pro-and anti-environmental subjective rules may be consistent predictors of pro-and anti-environmental intent.
