Family Functioning in Adolescents with Type 1 Diabetes: Comparisons with Healthy Peers and Associations with Metabolic Control

Objectives: Families play a pivotal role in the care of adolescents with chronic illnesses, such as type 1 diabetes (T1D). This study’s aim was to evaluate family functioning in families of adolescents with T1D and to assess its relationship with metabolic control. Methods: Fifty-eight adolescents and young adults diagnosed with T1D, aged 14–21 years, and 116 healthy adolescents (controls) matched for age, gender and socioeconomic status were included in this study. The participants’ mean age was 15.9 years (±1.6 years). The demographics and family functioning were reported by the participants. The McMaster Family Assessment Device (FAD) measured family functioning across six dimensions. Results: In problem-solving and behavioral involvement, T1D adolescents self-reported similar scores to healthy controls. On the contrary, in the domains of communication (p = 0.048), family roles (p = 0.045), affective responsiveness (p = 0.048), affective involvement (p = 0.043) and general functioning (p = 0.044), the T1D group scored lower than the controls, indicating better family functioning. Furthermore, within the T1D group, better metabolic control, assessed by glycated hemoglobin (HbA1c), was associated with a trend toward improved affective responsiveness, although this did not reach statistical significance (p = 0.091). Conclusions: Our findings highlight the importance of family functioning among adolescents with T1D and point toward distinct family processes that can be addressed in the context of routine care to enhance wellbeing and facilitate T1D management.
