Through the tunnel, to the light: Why sense of coherence covers and exceeds resilience, optimism, and self-compassion

Sense of coherence (SOC), resilience, dispositional optimism, and self-compassion are highly related aspects of personality that promote health and well-being. We systematically compared these constructs and explored their criterion validity when predicting psychological distress. With the help of structural equation modeling, we examined SOC's factor structure and incremental validity over resilience (N1 = 208) as well as over optimism and self-compassion (N2 = 308) in two studies. Despite strong overlap (shared variance) SOC clearly outperformed its competitors. Neither resilience, nor optimism, nor self-compassion had significant incremental validity over SOC on a latent level. A two-factor model for SOC explained most variance in psychological distress. Results highlight the importance of salutogenic factors even in a neck-to-neck comparison with other potentially health-benefitting personality variables. Meaningfulness appears to contribute to SOC's uniqueness.
