Objectives:
The aim of the study was to examine the relationship between psychosocial predictors, i.e. sense of coherence, self-esteem, self-perception, coping with problems, social support and quality of life in a sample of adults with physical disabilities.

Material and methods:
A diagnostic survey method and the following instruments were used: Orientation to Life Questionnaire by Antonovsky, Tennessee Self-Concept Scale by Fitts, The Ways of Coping Questionnaire by Folkman and Lazarus, Norbeck Social Support Questionnaire, Quality of Life Questionnaire by Schalock and Keith. It was hypothesized that higher levels of quality of life would be linked to higher levels of the predictors. A multiple regression analysis was employed for the hypothesis testing.

Results:
General social support, instrumental support and sense of coherence (SOC) may be considered the best psychosocial predictors of high quality of life (QOL). Higher general social support levels allowed a prediction of higher QOL in reference to independence and social integration. Higher levels of instrumental support were linked to higher general QOL, including productivity and independence. The strong, global SOC was predictive of higher QOL with regard to satisfaction. However, meaningfulness (SOC dimension) was a good predictor of higher QOL in terms of social belonging and community integration. The hypothesis was partially supported.

Conclusions:
Taking into account the practical implications of the results, perceived social support and sense of coherence are the most important factors. Rehabilitation programs aimed at raising the quality of life among people with disabilities could be enhanced by improving the social skills in establishing social network ties, recognizing an individual’s need for support and strengthening the sense of coherence.
