Predictors of Health-Related Quality of Life of Pregnant Women Based on Pender’s Model Constructs

This study aimed to investigate the predictors of health-related quality of life in pregnant women based on Pender’s health promotion model.

In this descriptive correlational study, 300 pregnant women in the second and third trimesters of pregnancy were selected by simple random sampling from one of the community health centers of Yazd province. Data were collected through a demographic information questionnaire, a short-form health survey v.1, and a questionnaire based on Pender's model constructs. Finally, the obtained data were analyzed descriptively using SPSS 18 software.

The psychological dimension of quality of life was significantly correlated with perceived effects, perceived self-efficacy, and perceived benefits (p<0.05). Also, the physical dimension of quality of life had a significant correlation with perceived barriers, social support, affect, and benefits (p<0.05). The regression analysis results showed that the variables of perceived barriers, social support, positive and negative effect, and perceived benefits had significant effects on the physical dimension of health-related quality of life (p<0.002). Moreover, the variables of positive and negative affect, self-efficacy, and perceived benefits influenced the psychological dimension of health-related quality of life (p<0.001).

According to the results, perceived effect, perceived self-efficacy, and perceived benefits constructs are suitable for the psychological dimension of health-related quality of life, perceived barrier constructs, and social support effects. The perceived benefits are appropriate for predicting the physical dimension of quality of life.
