Objective: To develop specific aphasia screener for adults in Urdu language.
Study Design: Comparative cross Sectional study.
Place and Duration of Study: Speech therapy clinic of National Institute of Rehabilitation Sciences, Islamabad Pakistan, from Nov 2016 to Apr 2017.
Methodology: A specific aphasia screener in Urdu was developed by an expert committee, relevant to local clinical and cultural setting, pilot tested, revised and used in main. Sample size was attained using consecutive sampling technique. Sample included 50 aphasic adults aged 40-70 of both genders, divided into 25 being allocated in Control Group and 25 in experimental group. Experimental group was subjected to the Urdu screener, while Control Group subjected to informal assessment.
Results: There was no significant difference in age and gender statistics between control and experimental group with p=0.765 and p=0.245 respectively, there was statistically significant difference in time of application between the two groups (p<0.001) assessment time of 36-40 minutes in majority and no assessment completed before 25 minutes while in the experimental group, majority of assessments were completed in 15-20- and 21-25-minutes group. Cronbach alpha value of 0.747 of Specific Aphasia Screener proved its internal consistency.
Conclusion: Specific Aphasia Screener in Urdu is simple, precise, reliable and applicable in short time to assess the language competence of patients with aphasia.
To develop a specific aphasia screener for adults in the Urdu language.
A comparative cross-sectional study was conducted. An expert committee developed the Specific Aphasia Screener in Urdu (SAS-U) based on local clinical and cultural settings, pilot tested, and revised it. The study involved 50 aphasic adults aged 40-70, divided into an experimental group (n=25) who received the SAS-U, and a control group (n=25) who received informal assessment. Data was analyzed using SPSS, with Cronbach's alpha for internal consistency and independent sample t-test for comparing groups.

The SAS-U is a simple, precise, and reliable tool for assessing language competence in Urdu-speaking patients with aphasia. Its short application time and culturally relevant items make it suitable for local populations, including the aged and illiterate. The study highlights the need for language-specific assessment tools.
- The SAS-U demonstrated good internal consistency with a Cronbach's alpha value of 0.747.
- The mean application time for the SAS-U was significantly shorter (1.68±0.690 minutes) compared to the informal assessment (4.60±0.645 minutes) (p<0.001).
- There were no significant differences in age (p=0.245) and gender (p=0.765) between the experimental and control groups.
The Specific Aphasia Screener in Urdu (SAS-U) is a simple, precise, reliable, and time-efficient tool for assessing language competence in Urdu-speaking patients with aphasia. It is culturally appropriate and can be used on aged and illiterate individuals.
- The study was conducted from November 2016 to April 2017.
- The sample size was 50 aphasic adults, divided into two groups of 25 each.
- The Cronbach's alpha value for the SAS-U was 0.747.
