Norwegian translation and validation of a routine outcomes monitoring measure: The treatment outcome package

To evaluate the factor structure and clinical validity of a Norwegian translation of the treatment outcome package (TOP). Exploratory factor analysis was used to confirm the factor structure of the TOP (n = 334). Samples collected from university students (n = 137) were used to evaluate 1-week test–retest reliability. Concurrent validity was examined using data collected from a hospital sample (n = 197), who completed several referent measures. Logistic regression (n = 293) was applied to determine the translated TOP's ability to differentiate between clinical and non-clinical samples. A 12-factor solution was the best-fit for the data, largely supporting the US TOP structure. One-week test–retest reliability ranged from ICC = 0.56 to ICC = 1.00. Internal validity ranged from α = 0.49 to α = 0.93. The TOP subscales correlated most highly with referent measures or appropriate subscales. Logistic regressions correctly identified 77% of subjects as clinical or non-clinical. Conclusions: While larger and more...
