The concept of social validity emerged in the 1970s with seminal articles by Wolf (1978), Kazdin (1977), andVan Houten (1979). They urged scholars in the field of behavioral sciences to ensure interventions were important to clients' lives and could be sustained in community settings. Since the 1970s, the importance of social validity has been accepted widely and is now considered an imperative aspect of intervention research in special education (Horner et al., 2005). This is in part because experts posit a relationship between social validity and intervention fidelity (Heckaman, Conroy, Fox, & Chait, 2000;McDuffie & Scruggs, 2008). When the social validity of an intervention is low, teachers are less likely to implement it as it was intended, if at all. The importance of social validity has also entered conversations about the longstanding research-to-practice gap. When teachers do not consider interventions to be feasible, acceptable, or relevant to their work, they may be less likely to adopt and sustain them over time (Greenwood & Abbott, 2001).
The Use of Qualitative Methods in Social Validity ResearchTypically, social validity is examined using questionnaires, rating scales, or direct observations by trained raters (Finn 524002R SEXXX10.
