Frozen shoulder and the Big Five personality traits
It is often speculated that a frozen shoulder is more common in patients demonstrating specific personality traits. However, the evidence on this subject is contradictory. This study further explored a possible relationship between frozen shoulder and the “Big Five” personality traits: Neuroticism, Extraversion, Openness, Altruism/ Agreeableness and Conscientiousness.
A frozen shoulder was established based on a general loss of shoulder ROM, particularly in external rotation, abduction and forward flexion. Patients in the frozen shoulder group were divided into primary (i.e. no cause) or secondary (clear cause can be identified) frozen shoulder. Secondary frozen shoulders were then subdivided in systemic (e.g. diabetes mellitus), nonsystemic intrinsic (e.g. rotator cuff disease) and nonsystemic extrinsic (e.g. cerebrovascular accidents). All patients completed the Dutch version of the Neuroticism-Extraversion-Openness to New Experience Five-Factor Inventory (NEO-FFI).
Although the authors suspected that patients with idiopathic frozen shoulder would score higher on Neuroticism than patients with secondary frozen shoulder and healthy controls, only a few minor differences were present between groups – this study does therefore not provide ground for the assumption of such thing as a frozen shoulder personality.
