Designed to address the concept of life satisfaction as a whole rather than to assess satisfaction with sub-dimensions of life (Diener et al. 1985).
Conceptually, the SWLS measures the ‘discrepancy or balance’ between one’s life achievements and expectations.
The SWLS is generic, in that it holds no bias due to particular disability (e.g. SCI). It has adequate psychometric properties across various populations and scores can be compared between these populations.
One item on the questionnaire “if I could live my life over, I would change nothing” is potentially sensitive.
