A questionnaire to evaluate the knowledge and attitudes of health care providers on pain.
The aims of this study were to survey the knowledge and attitudes of Italian health care professionals toward pain and develop a valid instrument to assess pain knowledge of physicians and nurses. A 21-item questionnaire on a Likert scale was given to 4,961 health professionals in 20 hospitals in Italy who volunteered to participate in the study. The results were analyzed psychometrically in three phases: the Principal Component Analysis phase identified two components, of which only the one that had 10 items about pain knowledge and attitudes (PAK) was studied; the Homogeneity Analysis revealed its acceptable internal reliability (Cronbach's alpha=0.72) and confirmed the Likert equidistance of the item options response; and the Confirmatory Factor Analysis proved that it had a very good construct validity. A standardized score was calculated on the PAK questionnaire using the final 10 selected items, considering 100% as the best level of knowledge of pain management and 0% as the worst. The standardized mean score on the whole sample was equal to 52.6% (95% Confidence Interval: 52.3%-53.0%). There was a statistically significant difference (P<0.001) in percentage score between physicians (56.5%) and nurses (51.3%). Knowledge was best among physicians in Anesthesiology and Emergency; this was followed by doctors in Medicine and then surgeons. The knowledge of nurses was almost constant. This scale fills a void by providing a validated instrument for testing the general knowledge about pain treatment of hospital staff. It is brief and can easily be administered to a considerable number of people.
