“…The AHI has already been frequently used in positive psychology intervention studies (e.g., Andrewes, Walker, & O'Neill, 2014;Gander, Proyer, Ruch, & Wyss, 2013;Mongrain & Anselmo-Matthews, 2012;Mongrain, Chin, & Shapira, 2011;Schueller, 2011Schueller, , 2012Senf & Liau, 2013;Sergeant & Mongrain, 2014;Shapira & Mongrain, 2010) and was also used in a broad range of other, non-intervention type studies (e.g., Ding, Mullan, & Xavier, 2014;Howell, Passmore, & Buro, 2013;Mullan & Xavier, 2013;Park, Monnot, Jacob, & Wagner, 2011;Parks, Della Porta, Pierce, Zilca, & Lyubomirsky, 2012;Proyer, 2014;Ruch, Proyer, Harzer, Park, Peterson, & Seligman, 2010;Schiffrin & Nelson, 2010;Toner, Haslam, Robinson, & Williams, 2012;Zabihi, Ketabi, Tavakoli, & Ghadiri, 2014). In a recent study, Kaczmarek, Bujacz, and Eid (2014) examined whether the AHI is more sensitive to situational changes than Diener et al's (1985) Satisfaction with Life Scale (SWLS) over three measurement periods within 15 months in a sample of young adults. The findings suggest that both instruments converge well and were similarly related to occasion-specific influences in their sample.…”
