Background. Asthma is a complex disorder characterized by variable and recurring symptoms, airflow obstruction, bronchial hyperresponsiveness, and an underlying inflammation. Asthma is one of the most common chronic diseases in the world and its burden of disease is exceedingly high. According to current guidelines, the asthma action plan is a cornerstone in the management and control of asthma exacerbations. Written action plans are now recommended for all children with asthma as part of initial home management of acute wheezing episodes and exacerbations. Translating the written asthma action plan to Filipino and testing it for cultural content validity and reliability will make it useful on a wider scale in our country, help reduce morbidity, and improve asthma control in the Filipino pediatric population.

Objectives. To perform content and cultural validation and reliability testing of the Filipino Written Asthma Action Plan (FWAAP).

Methods. The Written Asthma Action Plan was translated to Filipino following conventional translational steps: 1) forward translation, 2) back translation, 3) pilot testing and validation, 4) final translated version. We conducted a cross-sectional study and administered the FWAAP during pilot testing among children and caregivers with asthma attending an asthma clinic.

Results. We included 31 patients. The participants considered the FWAAP to be relevant to their disease, understandable, concise and useful in the management of asthma. The tool was shown to be highly consistent (Cronbach's alpha coefficient = 0.9235 showing that the. Seigel and Castellan's Kappa (Inter-rater or Inter-observer consistency) showed inter-rater agreement of 0.9615 (kappa of 0.7787) and 0.923 (kappa of 0.8846) respectively showing adequate inter-rater agreement.

Conclusion. The Filipino asthma action plan is a reliable and valid tool for managing asthma in the home setting.
