“…Further, a number of risk factors classified by Worling and Långström as unlikely were found to be predictive in the meta-analysis by McCann and Lussier. Similar inconsistencies are reflected in the findings of individual studies (e.g., Rasmussen, 1999;Smith & Monastersky, 1986), which, as noted above, are also characterized by problems such as brief follow-up periods (e.g., Kahn & Chambers, 1991;Prentky et al, 2000), small sample sizes (e.g., Boyd, 1994;Miner, 2002), unclear reliability (e.g., Allan et al, 2003;Smith & Monastersky, 1986), and the absence of a systematic, theoretically and empirically-based framework to inform the selection of risk factors (e.g., Nisbet et al, 2004;Rasmussen, 1999).…”
