The present study aims to test the hypothesis that a multi-component 6-week PPI programme will lead to a significant decrease in depression, anxiety, stress, and negative emotions, as well as to a significant increase of well-being, life satisfaction and positive emotions. To conduct the study, participants were recruited online and formed the experimental (N = 13) and control (N = 13) groups. Each participant completed a battery of self-reported questionnaires before, after and 3-month following the completion of the programme. The self-reported questionnaires completed were the Depression, Anxiety, Stress Scale, DASS-21, the Mental Health Continuum Short Form, MHC-SF, the Scale of Positive and Negative Experience, SPANE and the Satisfaction with Life Scale, SWLS. The results support our hypothesis that PPIs could be considered as a successful alternative intervention to people with symptoms of depression, anxiety, or stress.
