Key: ALSFRS = Amyotrophic Lateral Sclerosis Functional Rating Scale — revised; HADS = Hospital Anxiety and Depression Scale — Depression; D = Depression; A = Anxiety; NFI-MND = Neurological Fatigue Index-Motor Neurone Disease; SWS = Social Withdrawal Scale.
Spearman's rank correlations all significant at p < 0.05. Effect sizes below .3 suppressed.
