Illness Perceptions and Illness Identity in Adolescents and Emerging Adults With Neuromuscular Disorders.

BACKGROUND

Neuromuscular disorders (NMD) are intrusive medical conditions with implications for psychosocial development.

OBJECTIVES

This paper explores illness perceptions and illness identity dimensions of youth with NMD. First, we compare illness identity outcomes and illness perceptions of NMD patients with a comparison group of adolescents with type 1 diabetes mellitus (DM). Second, we report about the relationships between NMD-related variables and illness perceptions and illness identity.

METHODS

Scores on the Brief Illness Perception Questionnaire and the Illness Identity Questionnaire were compared between a group of NMD patients (N = 59; 12-22 years) and an age- and gender-matched group of DM patients (N = 118). NMD-related variables included time since diagnosis, prognosis, wheelchair use, and physical limitations.

RESULTS

Youth with NMD scored significantly higher on two of the four illness identity dimensions than youth with DM. NMD patients reported significantly less positive illness perceptions, experienced more physical symptoms, and had a lower score on understanding of their illness. Within the NMD group, wheelchair-users have a better understanding of their disease than those who are not wheelchair-bound.

CONCLUSIONS

The present study is the first to investigate illness identity and illness perceptions in NMD. More research is needed to provide insight in the identity formation process of the growing group of adolescents with NMDs.
