VALIDATION OF PAKISTANI VERSION OF REYNOLDS ADOLESCENT DEPRESSION SCALE –SECOND EDITION

Abstract

Objective: The present study aims to estimate the convergent and concurrent validity of Pakistani version of Reynolds Adolescent Depression Scale –Second Edition (RADS-2U)[1] originally developed by Reynolds[2].

Place and Duration of study: Karachi, Year 2012

Sample and Method: A sample of adolescent students between the age range of 12-20 years from different educational organizations in Karachi, Pakistan were taken in this study through using convenience sampling method. In order to estimate the convergent and concurrent validity, the Pakistani version of Reynolds Adolescent Depression Scale-2 (RADS-2U)¹ along with the Pakistani versions of Rosenberg self-esteem scale[3], originally developed by Rosenberg[4], Social Support Questionnaire[5] originally developed by Sarason et al.[6], and Index of Family Relation[7] originally developed by Hudson[8], were administered on 216 adolescent students. The RADS-2U¹ and Siddiqui-Shah Depression Scale (SSDS)[9] was also administered on 100 student adolescents (age 17-20). Pearson product moment correlation coefficients were calculated in order to examine the convergent and concurrent validity of the Scale (RADS-2U¹).

Results: The convergent and concurrent validity of the RADS-2U¹ was demonstrated via significant correlation (.738 at the .01) with Siddiqui-Shah Depression Scale⁹, with RSES³   (-.503 at the .01), with SSQ-6⁵(-.366 at the .01)   and with IFR⁷ (.317 at the .01). 

Conclusion: The Pakistani version of RADS-2² shows acceptable psychometric properties and appears to be a valid measure for cross cultural use.
