Parental perceptions about severity of a disease in their child are important to enhance the acceptance of disease and ensure compliance of interventions. However these perceptions, generally reliable, might not always correlate with more objective assessments. Severity of childhood Asthma is usually assessed as per Global initiative for Asthma (GINA) guidelines and studies have shown only a modest correlation between GINA based assessment and parental perceptions. Objectives: To assess perception of the parents regarding severity of asthma in their children and correlate it with objective assessment as per GINA Guidelines. Methods: In a cross-sectional observational study involving 77 children with Asthma, severity of the disease was assessed as per GINA guidelines, termed as Clinical Severity score (CSS-GINA). Then, one of the parents was interviewed for their perception about it, using a pre-validated questionnaire including fifteen questions in three fields - Day-time symptoms (DTSS), Night-time symptoms (NTSS) and Disability status (DDS). Results: There was a significant difference in PPSS between children with well-controlled asthma (08.52±5.17) versus those with partly-controlled (13.91±4.89) or uncontrolled disease (21.31±0.51). There was also a good correlation between CSS-GINA and PPSS as well as all of its sub-groups, being strongest with DTSS (r: 0.62) and weakest with DSS (r: 0.38). Both parents had excellent perception of their ward’s illness, though the mother’s perception had marginally stronger correlation than that of fathers. Perception of the severity was better among parents who themselves had disease (R-value 0.67 vs. 0.54). Conclusions: Parents have reasonably good perception of the disease status in their asthmatic children, though it might be inadequate regarding the disability or the impact of the disease on the quality of life. Reliability of this subjective perception also depends on certain
