Participants completed validated instruments with established psychometric properties, namely the Brief Illness Perception Questionnaire, the Medical Coping Modes Questionnaire, the Perceived Social Support Scale, and the Self\u2010Regulatory Fatigue Scale.

Serial mediation analysis revealed that illness perception was associated with SRF through indirect pathways involving resignation coping and social support.

This observed correlation is additionally linked to indirect pathways involving resignation coping and lower social support.
