Adolescents diagnosed with a chronic illness such as type 1 diabetes mellitus (T1DM) face the typical physical and psychosocial challenges associated with adolescence, as well as the additional challenges of having to cope with the daily stressors of living with a chronic illness. In order to explore coping strategies in this population of adolescents, and to compare the constructs with those identified by the Adolescent Coping Scale (ACS), four focus groups were conducted with 13 adolescents with T1DM. The qualitative data was analysed using content analysis and grouped according to the ACS. Prevalent nonproductive coping strategies included Tension Reduction (the use of maladaptive techniques to reduce tension/stress), Ignore the Problem and Keep to Self. Prevalent productive coping strategies included Seek Social Support, Physical Recreation and Seek Relaxing Diversions. The qualitative data not only affirmed the conceptual areas of the ACS for use with adolescents with T1DM, but also highlighted the need to teach coping strategies to adolescents with T1DM to give them an additional skill set to help them better manage the challenges of diabetes.
