Suppose an ABCD design obtains the following results regarding level of social adjustment with a chronically mentally ill client discharged to live with his family.
$$\begin{array} { l l l l l l }
\text { A (Baseline): } & 10 & 10 & 10 & 10 & 10 \
\text { B (Social skills training): } & 10 & 10 & 10 & 10 & 10 \
\text { C (Occupational Rehabilitation): } & 10 & 10 & 10 & 10 & 10 \
\text { D (Family education): } & 15 & 20 & 25 & 30 & 35
\end{array}$$
What is the most appropriate inference for future interventions with similar clients?
A)Just provide the family education.
B)Provide all three interventions in the same order.
C)Replicate the study to assess possible order effects.
D)none of these.

The results suggest a clear improvement in social adjustment only after the introduction of the family education intervention. However, it is uncertain if this outcome is due to the intervention itself or to a possible order effect (i.e., the combination of training and rehabilitation interventions may have prepared the client and family for the final family education intervention). Therefore, it is recommended to replicate the study with different orders of interventions to assess possible order effects and confirm the efficacy of family education as a standalone intervention. Providing all three interventions together may also be effective, but it is unclear from the current data.
