Abstract: This study translated and validated the Substance Use Risk Profile Scale (SURPS) among 13 to 18 year old Sri Lankan adolescents attending school. A standard systematic translation procedure was followed to translate the original SURPS into Sinhala language. A Delphi process was conducted to determine judgmental validity of Sinhala SURPS. Confirmatory factor analysis was performed to test the translated version against the original theoretical model of the SURPS. Test-retest and internal consistency were used to ensure reliability. A few terms in one of the items posed some difficulty in translating into Sinhala. Adequate judgmental validity was determined except for one item, which was modified to suit the Sri Lankan setting. The four subscales introversion/ hopelessness, impulsivity, sensation seeking and anxiety sensitivity showed satisfactory test-retest reliability estimates of .74, .68, .76, and .88, respectively. The Sinhala SURPS is applicable in Sri Lankan context. Several implications based on the results are discussed.
