This research aims to investigate the rate and nature of anxiety symptoms in a group of children and adolescents living with chronic illnesses in Jordan, and their relation to social desirability in a cultural sample not previously researched. Using the Revised Children's Manifest Anxiety Scale (R-CMAS), anxiety and social desirability data were obtained from 114 children diagnosed with chronic illnesses and 162 healthy control participants. Based on children's self-report, participants were categorized according to their adaptive style paradigm as either high anxious, low anxious, or repressor. It was proposed that children who score high on social desirability and low on anxiety are repressors. The prevalence of these categories was compared across the two groups. Anxiety was reported in 9.64 percent of the chronic illnesses and 12.34 percent of the healthy peers. Using the data obtained in the present study, the rate and nature of anxiety in children with chronic illnesses were lower for children in Jordan when compared to previous studies. However, social desirability values were similar to those established in Western societies suggesting a significantly higher percentage of children identified as repressors in children with long-term illnesses. These results supported the hypothesis regarding the relationship between social desirability and expressed anxiety symptoms
