Descriptions of quantitative instruments used within the study to assess quality of life, generalized anxiety and depressive symptoms

Instrument	Description and Cronbach’s alpha Score
Lymphedema Quality of Life (LYMQOL-leg) Tool	This 27-question survey evaluates the impact of LEL on QOL. Question domains included symptoms, appearance, function and mood. Overall QOL scores are reported in this paper, where higher scores indicate greater QOL (α = 0.83–0.88) [15].
Functional Assessment of Cancer Therapy-General (FACT-G)	The FACT-G is a 27-item questionnaire, which evaluates QOL of those experiencing chronic illness [16]. The FACT-G is segmented into four domains: physical, social/family, emotional, and functional well-being, and there is a total score. Higher scores indicate better QOL (α = 0.89) [17].
Generalized Anxiety Disorder (GAD-7)	This 7-item questionnaire assesses the level of generalized anxiety experienced by patients. Higher scores indicate increased anxiety (α = 0.89) [18].
Patient Health Questionnaire (PHQ-8)	This 8-item questionnaire evaluates severity of depression. Higher values indicate increased frequency of depressive symptoms. A score of ≥ 10 is indicative of a high level of depressive symptomatology (α = 0.87) [19].
