Abstract:
Background: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized 
by impairments in social interaction, communication and limited habitual activities and interests. 
Clinical characteristics of this disorder lead to barriers in managing individual, child health and 
their families. Psychological impact associated with caring is significant and the study field needs 
to be explored.  
Objective: To assess the psychological impact among primary caregivers of children with ASD at 
selected autism treatment centres in Colombo municipal area 
Methods: A descriptive cross-sectional study was conducted among consented primary caregivers 
(n=105) of children with ASD from three selected autism treatment centres in Colombo municipal 
area, Sri Lanka. Data were collected using a self -administered questionnaire. Psychological 
impact was assessed using validated Depression, Anxiety and Stress scale (DASS 21). Data 
analysis was carried out (descriptive and inferential statistics) using SPSS version 25.0.  
Results: The mean±SD age of the primary caregivers was 37.35±8.03 years. The majority of 
caregivers of children with ASD were mothers (85.7%, n=90). Majority of the participants were 
unemployed (86.6%, n=91) and lives in an urban area (90.5%, n=95).  The mean score for 
depression, anxiety and stress among participants were 17.87, 11.54 and 23.45 respectively. The 
highest percentage of primary caregivers had moderate level of depression (45.7%, n=48), anxiety 
(38.1%, n=40), and stress (48.6%, n=51). Severe depression, anxiety and stress were experienced 
by 5.7% (n=6), 24.8% (n=26) and 16.2% (n=17) of caregivers respectively. Depression was 
associated with age (p=0.000), nationality (p=0.049) and residential place (p=0.005). Anxiety was 
also associated with age (p=0.002), nationality (p=0.012) and residential place (p=0.045) while 
stress was also associated with age (p=0.000), nationality (p=0.002) and residential place 
(p=0.014) of the caregiver.  
Conclusions: A considerable proportion of primary caregivers experience depression, anxiety and 
stress associated with caring for children with ASD. Strategies need to be encouraged to enhance 
the psychological wellbeing of the primary caregivers.
