“…Six articles used multiple
case study designs with baseline, post-treatment, and follow-up assessments
(Craig et al, 2006; Lindsay, Marshall, Neilson, Quinn, &
Smith, 1998; Lindsay, Neilson,
Morrison, & Smith, 1998; Lindsay, Olley, Baillie, & Smith, 1999; Rose, Jenkins, O’Connor, Jones,
& Felce, 2002; Sakdalan
& Collier, 2012), and one multiple case study design was
included with no follow-up assessment (Singh
et al, 2011). Finally, three studies employed quasi-experimental
designs (Keeling, Rose, & Beech,
2007; Lindsay, Michie, Steptoe,
Moore, & Haut, 2011; Michie & Lindsay, 2012). Michie and Lindsay (2012) designed a study consisting of two
groups of sex offenders with IDD.…”
