B, unstandardized beta; SE B, standard error; DASS-21, Depression, Anxiety and Stress Scale; QoL, Quality of Life; NEO-FFI, NEO Five-Factor Inventory. For all predictors, positive B = positive predictive value (improvement related to increased values of the predictor) and negative B = negative predictive value (worsening related to increased values of the predictor). Categorical predictors codification: sex (male – 0; female - 1), employment status (unemployed – 0; studying – 1; working – 2), living with teenagers (no – 0; yes - 1), living with elderly (no – 0; yes - 1), having a diagnosis of a psychiatric disorder (no – 0; yes - 1), having a diagnosis of a physical disorder (no – 0; yes - 1), consumption of substances several times a week (no – 0; yes – 1).
