Social validity
Definition
The extent to which the people affected by services, such as clients, caregivers, teachers, and the community, find the goals, procedures, and results acceptable, important, and worthwhile.
In plain words
A behavior plan can produce change on a graph and still fail if the family does not value the goal, cannot stand the procedure, or does not notice any difference in daily life. Social validity asks three questions: are the goals important, are the procedures acceptable, and do the results matter to the people involved? Plans with strong social validity are more likely to be carried out consistently and to produce lasting change.
Example from a session
After a month of a toileting program, the BCBA asks the family to rate how worthwhile the goal was, how easy the steps are to do at home, and how much daily life has changed. The parents rate the goal highly but say the 30-minute sit schedule is hard to follow on school mornings. The RBT, who sees the routine firsthand, shares objective observations with the BCBA, who adjusts the schedule with the family.
For BCBA candidates and supervisors
Analysts assess social validity with questionnaires and interviews, by comparing the client's performance with that of typical peers (normative comparison), by having consumers choose among procedures (treatment preference), and by asking whether the change is noticed by others. Social validity should be assessed before and during intervention, not only at the end, and should include the client's own perspective wherever possible, including assent. Cultural responsiveness and contextual fit are closely tied to it: a socially valid plan fits the family's values, routines, and resources.
Often confused with social significance, contextual fit
Social significance is a property of the behavior or outcome: whether changing it improves the person's life. Social validity is how the people affected judge the goals, procedures, and results, which is how social significance is usually assessed. Contextual fit is whether a plan matches the setting's values, skills, and resources, which strongly affects acceptability.
Exam tip
If a stem asks how to find out whether a family thinks the goals and procedures are acceptable, the answer is a social validity assessment. Remember the three levels: goals, procedures, and outcomes.
