“…The studies were conducted in Turkey (Akinci & Olgun, 2011), Australia (Cooke, Moyle, Griffiths, & Shields, 2010;Wood-Baker, Reid, Robinson, & Walters, 2012), Iceland (Ingadottir & Jonsdottir, 2010), China (Liu et al, 2013), Japan (Moriyama, Takeshita, Haruta, Hattori, & Ezenwaka, 2015), Korea (Oh, 2003) In this category, one RCT was identified (Liu et al, 2013) and two studies with a two-group pre-post design (Akinci & Olgun, 2011;Moriyama et al, 2015). These three studies used the SGRQ and included an online video-based breathing programme (Liu et al, 2013), education about COPD and performance of breathing exercises and physical training (Akinci & Olgun, 2011), or a nurse-led self-management educational programme that included an interactive workbook, learning materials and journal for self-monitoring (Moriyama et al, 2015). One study reported a positive effect in favour of the experimental group (MD = 15.6-18.2, p < 0.05) for all of the SGRQ scores (Liu et al, 2013).…”
