Abstract:The number of people suffering from type 2 diabetes has been growing recently. This chronic disease is connected with lower perceived quality of life and experiencing a lot of stressful situations. Some of these situations can be anticipated. Thus, it is possible to prepare oneself for future difficult situations by using proactive coping strategies. Polish Psychological Bulletin 2015, vol. 46(3) 362-375 DOI -10.1515/ppb-2015 According to the World Health Organization (1993) quality of life is defined as an individual's perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns.
The aim of this research was to verify the level of satisfaction with various areas of life, the frequency of use of proactive coping strategies in the case of type 2 diabetes patients and healthy individuals, as well as mediation role of these strategies in the relationship between positive emotionality, cognitive curiosity and perceived quality of life.

Current statistics show that three million people in Poland suffer from diabetes, whereas only 2/3 of this group has been diagnosed (Novo Nordisk, 2014). This disease was described by the UN at the end of 2006 as the first among the epidemics of the 21st century (Silink, 2007). Diabetes is considered to be one of the main health care problems these days, both from a medical and socioeconomic point of view (Tatoń, Czech, & Bernas, 2008). It affects people regardless of their race or the place they live.

This indicates that the significance of this parameter is related, among other things, to finding its determining factors.

The quality of life among people suffering from diabetes deteriorates with age ...
