A conceptual model of strong school-based interventions is presented.
Strong interventions are ecological in nature, naturalistic in scope,
contain elements from the research base that are predictive for succes
s, and incorporate the constructs of social validity in a practical ma
nner. The latter concept relates to the ideas of treatment acceptabili
ty and socially important outcomes, and is important for insuring trea
tment integrity. While there exists a robust research data base for ef
fective school interventions, generalization to regular school setting
s without the overriding influence of researcher/consultant is difficu
lt. Thus, all of these concepts must be practically utilized if strong
interventions are to be applied to school problems. Suggestions and i
mplications for school psychology practitioners are discussed.
