“…The sample is not representative of the target population in four studies (McCabe & Somers, 2009;Monay et al, 2010;Thompson, 2010;Tormoehlen, 2009) and insufficiently reported to determine sample representativeness in two studies (King & Tessaro, 2009;Ziebarth, 2018). Measures are insufficiently described to determine appropriateness in 11 studies (Bokinskie & Kloster, 2008;King & Pappas-Rogich, 2011;King & Tessaro, 2009;McCabe & Somers, 2009;McGinnis & Zoske, 2008;Monay et al, 2010;Pappas-Rogich & King, 2014;Reilly et al, 2011;Thompson, 2010;Tormoehlen, 2009;Ziebarth, 2018). Non-response bias is not low in six studies (McCabe & Somers, 2009;McGinnis & Zoske, 2008;Monay et al, 2010;Thompson, 2010;Tormoehlen, 2009;Ziebarth, 2018) and indeterminate in four studies (Bokinskie & Kloster, 2008;Hixson & Loeb, 2018;King & Pappas-Rogich, 2011;King & Tessaro, 2009).…”
