Treatment Integrity of School-Based Behavioral Intervention Studies: 1980-1990

Treatment integrity (the degree to which a treatment is implemented as planned) represents a key concept in school-based intervention and is considered to be a link between use and effectiveness of interventions. Its demonstration represents one of the most important aspects of both scientific as well as as practical applications of interventions in school settings. A total of 181 experimental studies published between 1980-90 in seven journals known for behaviorally based interventions was reviewed. Of primary interest was whether or not integrity was assessed, the degree of treatment integrity, operational definitions of treatments, and effect sizes produced by interventions. Only 14.4% (26 studies) systematically measured and reported integrity data; only 34% (65 studies) operationally defined treatments. Moderate positive correlations were found between degree of treatment integrity and level of treatment outcome. Recommendations for future research and practice centered on operational definition of treatments, measurement of treatment integrity, and alternative methods for assessing treatment integrity.
