The present study examined the associations between a high-K (slow) life history strategy and depressive symptomatology. The participants were a sample of 494 male utility workers who underwent psychological evaluations. It was hypothesised that high-K will correlate negatively with, and will be a negative predictor of, depressive symptomatology. The results confirmed the predictions, showing that high-K accounts for 15% of the variance in depressive symptomatology after controlling for risk factors for depression such as demographics, prior traumatic experiences, past depression, and recent negative life events. Implications of the results are discussed.
