Jaak Panksepp's primary emotions are associated with Diener's global life satisfaction: How low arousal of the SADNESS/separation distress system could form the core of life satisfaction?

We compared Ed Diener's (SWLS), which was designed as a purely cognitive measure of global life satisfaction, with the , which provides self-report measures of Panksepp's six primary emotions (excluding LUST), in two English-speaking samples: a main sample and a hold-out validation sample. Our data showed robust negative correlations between higher satisfaction with life and lower FEAR, lower SADNESS/Separation Distress, and positive associations (albeit less strong) between higher satisfaction with life and higher PLAY and SEEKING in both samples. The relationships between the SWLS and at least four of Panksepp's primary emotions suggest Diener's SWLS is not purely cognitive and includes a strong affective component. In addition, detailed analysis of the negative correlation between the SWLS and the ANPS 3.1 SADNESS scale provides insight into the importance of the low arousal end of the SADNESS/Separation Distress brain system and supports the idea of a continuum of psychological states from high SADNESS including loneliness and depression to low SADNESS psychological states characterized by social comfort, self-confidence, and social strength.
