Teacher adoption of substance abuse programs is highly variable. Principal involvement boosted implementation, but intensive training did not, highlighting the need for better strategies.

Area of Science:

  • Education
  • Public Health
  • Psychology

Background:

  • Investigating the diffusion of psychosocial substance abuse prevention programs in schools.
  • Examining teacher adoption, implementation, and maintenance of these programs.
  • Identifying factors influencing program fidelity and effectiveness.

Purpose of the Study:

  • To assess teacher adoption, implementation, and maintenance of a psychosocial substance abuse prevention program.
  • To identify teacher characteristics linked to successful program implementation.
  • To evaluate the impact of teacher training and principal involvement on program diffusion.

Main Methods:

  • A study involving 60 teachers, 25 principals, and 1147 fifth-grade students across four school districts.
  • Random assignment to intensive vs. brief teacher training and principal intervention vs. no intervention.

  • Data collection through self-reports, classroom observations, and outcome evaluations.

    • Main Results:

    • Initial implementation by 78% of teachers dropped to 25% in the second year.
    • Teachers who implemented the program had less experience but higher self-efficacy and perceived principal encouragement.
    • Principal intervention improved implementation rates; intensive teacher training did not.

    Conclusions:

    • Widespread teacher use of psychosocial prevention programs is not guaranteed due to variable implementation.
    • Effective strategies are needed to enhance program implementation and long-term maintenance in schools.
