Interpretation of "Treatment"

Hi~ In the sentence underlined, what could be the best interpretation of the word "Treatment"?

A medical care OR some method to address the current problem?

Thank you for your comments in advance.

The most difficult part of this approach is that educators are conditioned
to focus on the negative behavior and are not trained to design
replacement behaviors that can be practiced consistently while the student
is calm. Treatment determined a long time ago that recovery is not
linear. For example, resiliency research indicates that promoting specific
protective factors will diminish presenting problems even if there is no
direct correlation. In this case, protective factors are the skills identified in
resiliency research that help students overcome presenting issues. This
seems counterintuitive to most educators. If a student displays anger as
an issue, teachers believe that the replacement behavior must be an anger
management strategy the student is to do in times of crisis. However,
research does not support that position. This approach allows educators
to embed protective factors into daily class rituals, allowing students
increased opportunities to master the skill and the brain to reinforce it.
The key is to design the protective factors in a manner that the brain will
reinforce the practice.
