Abstract
This study examines whether the extent to which participants adopt the components of a multicomponent
health intervention influences its effectiveness. Although interventions are often
evaluated based on overall outcomes, less attention is given to differences in how participants
actually apply intervention components in daily life. This study therefore positions adoption as
a central explanatory construct and examines coping capacity as a moderator in this
relationship. Using a longitudinal, non-experimental design, secondary survey data were
collected at baseline and follow-up among 85 participants of Company X’s intervention.
Analyses were conducted to examine the relationship between adoption of seven intervention
components and stress level, physical and mental complaints, and well-being, while controlling
for demographic variables. The results show that stronger adoption of the AC-process and AT
components is associated with greater reductions in physical and mental complaints. However,
adoption did not significantly predict stress level or well-being. Coping capacity did not
moderate the relationship between adoption and the outcome variables. These findings suggest
that adoption plays a selective and component-specific role in intervention effectiveness.
