Quality of Life in Depression: Predictive Models

Abstract

The purpose of this study was to examine the predictive factors of quality of life for inpatients with depressive disorders. Eighty-three patients (mean age 44; 73% female) with depressive disorders were recruited from the psychosomatic ward of a medical center in the northern part of Taiwan. The predictive models of this study were established by encompassing three constructs: clinical variables, demographics, and perceived competence. The outcome variables of this study included an overall quality of life score and four domains' scores of the World Health Organization Quality of Life-brief version (WHOQOL-BREF). Stepwise regression analysis was used to identify significant factors related to the outcome variables. The results showed that there were five distinct models for the various domains of the quality of life. The predictive variables of the final model for overall quality of life included: the Beck Anxiety Inventory, the Canadian Occupational Performance Measure-satisfaction, and the Occupational Self Assessment-self. For the physical domain of the quality of life model, the adjusted Beck Depression Inventory-II, the Beck Anxiety Inventory, and the Activity of Daily Living Inventory were the significant predictors. In the psychological domain, the adjusted Beck Depression Inventory-II and age were the predictive factors. The adjusted Beck Depression Inventory-II, the Beck Anxiety Inventory and the Occupational Self Assessment-environment were the predictors for the social domain of quality of life. Finally, the adjusted Beck Depression Inventory-II, age, and the Occupational Self Assessment-environment were the predictors for the environmental domain of quality of life. The significance of the perceived competence variables in the quality of life of patients with depression indicates that occupational therapy intervention is warranted.

Differential effects of anxiety and depression on interoceptive accuracy

“…Though several studies [36,[44][45][46][47][48][49][50] have shown that low scores in depression as measured by the BDI in healthy participants are valid assessments of depressive symptoms, which can be interpreted meaningful Figure 1. Scatter plots depicting the distribution between heartbeat perception and depression as well as between heartbeat perception and anxiety.…”

“…[43] The inventory has been shown to be valid and reliable for both subjects with and without depressive disorders. [36,[44][45][46][47][48][49][50] Trait anxiety and depression scores were used for correlation and regression analyses between these variables and interoceptive awareness.…”

Is parental rearing an associated factor of quality of life in adulthood?

“…Assuming that upbringing determines coping strategies utilized by the subject facing stressful situations, which in turn impact onto quality of life, we conjectured that parental care could be associated with adult quality of life through the kind of coping strategies used. Current depressive symptoms and recent life events are included in this hypothesis as mediator variables [19,20].…”
