Tele-wound monitoring service requires the willingness of patient to perform self-wound care. In a qualitative study, personal attributes and wound-related factors were found to be barriers in accepting the self-wound care concept. However, these findings were not validated in a wider population thus the aim of the study was to develop and validate a local survey to identify the barriers in performing self-wound care at home.

Development and validation of this questionnaire was conducted in three phases. The questionnaire was evaluated by 6 content experts followed by piloting the questionnaire in 10 patients for relevancy and clarity. In the last phase, the questionnaire was evaluated for psychometric properties in 165 patients. Content validity index, internal consistency and exploratory factor analysis using principal components extraction and varimax rotation were utilised to validate the questionnaire.

The expert panel and pilot group participants evaluated the relevancy and clarity to be acceptable (expert agreement CVR=0.6, pilot group S-CVI/Ave=0.7). Cronbach alpha was 0.67, indicating a moderate level of internal consistency. Sampling adequacy was confirmed by Kaiser-Meyer-Olkin at 0.898. Exploratory factor analysis identified a four-factor solution including 15 items, accounting for 63% of the total variance. Benefits of self-wound care accounted for 39% of the variance; environmental factors and support 11%; wound procedure 6%; and wound condition 6%.

This study indicates that this is a valid and reliable instrument in assessing barriers in performing wound care at home. Health care professionals could use the questionnaire to address the patient’s concerns and promote self-wound care procedure.
