DEVELOPMENT OF A QUESTIONNAIRE TO ASSESS KNOWLEDGE, ATTITUDE AND PRACTICE OF PULMONARY REHABILITATION PROGRAM AMONG PHYSIOTHERAPISTS IN PUBLIC HEALTH CARE SETTING
Despite the benefits of Pulmonary Rehabilitation Program (PRP) on patients with chronic obstructive pulmonary disease (COPD), the implementation of the program remains low. An evaluation of knowledge, attitude and practice (KAP) particularly among physiotherapists as the PRP key players is therefore necessary. However, no KAP instrument for this practice area is available to date. This study intended to develop a KAP questionnaire which can be used to evaluate PRP implementation among physiotherapists working in the public health care settings. A questionnaire (KAP-PRP) was drafted based on findings of literature reviews and expert consultations. Content validation was performed with the involvement of six physiotherapy experts, while face validation involved 10 physiotherapists working in the medical discipline. The resulting 20-item questionnaire covering knowledge (10 items), attitudes (4 items), practice (5 items) and an open-ended item on possible barriers was then tested twice; initially on 152 physiotherapists, then on 70 physiotherapists from 16 Malaysian public hospitals to determine its construct validity and internal consistency, which were analyzed using factor analysis and Cronbach’s alpha. The questionnaire has high content validity index (CVI) score (Item-CVI between 0.83 and 1.00 and Scale level-CVI >0.96) and was rated well by the experienced physiotherapists. Cronbach’s alpha score of 0.58 for attitude, and 0.58 to 0.68 for practice domains, with average score of 0.68 were obtained, which indicate moderate, acceptable internal consistency. In conclusion, the KAP-PRP questionnaire is adequately valid and reliable, thus can be used to evaluate pulmonary rehabilitation program implementation among physiotherapists.
