Seventeen participants participated in the Quality of Life and Awareness Training (QLAT) and 19 participants did not participate in the QLAT.
The training goals of the QLAT were to increase self-esteem, belongingness, safety and perceptions of the physiological needs, and perceptions of self-actualization.
The dependent variables were the scores on the Wisconsin HSS Quality of Life Inventory and Awareness Questionnaire and the independent variable was the QLAT. The levels of the independent variable were participation and no participation in the QLAT.
So, it is possible that this study, that attempted to improve perceptions of quality of life through the QLAT, in fact, was influenced by the social interactions among participants in both the control and experimental groups.
