Abstract

Objective: the aim of the present study was the estimation of validation and reliability test of ASSIST instrument in Iran. Method: our research populations were Iranian alcohol and drugs users and abusers in the year 1390 that had referred to rehabilitation camps and addiction treatment centers for self-improving. Sample sizes of 2600, average age 36/5, were selected by cluster random sampling in eight provinces. The ASSIST and demographic form exercised for all of sample group. Also in order to validity estimation, 300 number of main sample we interviewed by ASI, SDS, DAST and DSM-IV criteria. Findings: ASSIST reliability estimated by Cronbach’s alpha for all of domains was between %79 to %95. Data analyses showed fair criteria, construct, discriminate and multi dimension validity. These types of validity for other domains were Discriminative validity of the ASSIST was investigated by comparison of ASSIST scores as groupes of dependence, abuser and user. There were significant confirmation between this scores and DSM-IV scores. Construct validity of the ASSIST was investigated by statistical comparison with health scores. ASSIST's cut off points classify clients in 3 categories in term of intensity of addiction. Conclusion: we surely recommend researchers to use this instrument in research and screening purposes or other situations in Iran.

Abstract

Background: Bender Gestalt Test is one of the most famous neuropsychological tests, simple and easy to perform, and is used to evaluate brain injuries. This study aimed at determining the rate of sensitivity, characteristic and cut-off point of this test in patients with traumatic brain injury (TBI). Methods and Materials: Overall, 120 TBI patients with mean age of 31.25± 13.60 years old in a descriptive-analytical research design entered the study using nonprobability and consecutive sampling method. All patients underwent Bender Visual-Motor Gestalt Test after neurological evaluations by CT scan. Roc curve test was utilized to analyze the data. Results: In this study, cut-off point was calculated as 6.5%, sensitivity as 55.8%, characteristic as 81.2%, and the area under the Roc curve as 0.69. Moreover, positive predictive value, negative predictive value and efficiency were 95.08%, 22.03%, and 59.17%, respectively. Conclusion: Results of this study revealed that Bender Gestalt Test is relatively weak in diagnosis of mild TBI. Hence, its characteristic is high and it was successful in diagnosing healthy individuals.
