Self-appraisals and episodic memory: Different psychological factors related to patient versus informant reports of apathy in severe traumatic brain injury

ABSTRACT

Introduction: Apathy is a core feature in patients with traumatic brain injury (TBI). The psychological processes underlying apathy are still unclear, and the few studies conducted on this subject have essentially focused on cognitive processes and informant reports of apathetic manifestations. The aims of the present study were to examine self-reports versus informant reports of diminished initiative/interest, as well as their relationship with different cognitive factors (attention/executive mechanisms, episodic memory, and multitasking) and personal identity factors (self-esteem and self-efficacy beliefs). Method: To this end, 74 participants (38 patients with severe TBI matched with 36 control participants) were given three questionnaires to assess self-esteem, general self-efficacy beliefs, and anxio-depressive symptoms and five tasks to assess cognitive processes, including real-life multitasking. In addition, a questionnaire that assessed self-awareness of functional competencies and a questionnaire that assessed lack of initiative/interest were administered to each participant and their relatives. Results: The main results showed that patients demonstrated an awareness of their lack of initiative/interest and that self-reported lack of initiative/interest was best predicted by low general self-efficacy beliefs and self-esteem, whereas informant-reported lack of initiative/interest was predicted by episodic memory difficulties. Conclusions: These results shed new light on the psychological processes related to apathetic manifestations, as well as the differing perspectives and lived experiences of patients and external observers in the TBI population, which opens interesting prospects for psychological interventions.
