The differential mediating effects of pain and depression on the physical and mental dimension of quality of life in Hong Kong Chinese adults.

Wong WS, Chan ST, Fung VB, Fielding R - Health Qual Life Outcomes (2010)

Bottom Line: About 44% of the sample had 3-5 painful areas in the past 3 months.Shoulder pain (60%) and headache (53%) were common painful areas.As these findings were based on a Chinese teacher sample, future studies should employ more representative samples across cultures to verify the present data.

ABSTRACT

Objective: The impact of pain and depression on health-related quality of life (QoL) is widely investigated, yet the pain-depression interactions on QoL remain unclear. This study aims to examine the pain-depression-QoL mediation link.

Methods: Pain severity were assessed in a sample of Chinese professional teachers (n = 385). The subjects were also assessed on depressive symptoms and QoL. Regression models were fitted to evaluate the pain-depression-QoL relationships.

Results: About 44% of the sample had 3-5 painful areas in the past 3 months. Shoulder pain (60%) and headache (53%) were common painful areas. The results of regression analyses showed that pain mediated the effects of depression on the mental aspect of QoL (standardized beta = -0.111; Sobel test: z = -3.124, p < 0.005) whereas depression mediated the effects of pain on the physical aspect of QoL (standardized beta = -0.026; Sobel test: z = -4.045, p < 0.001).

Conclusions: Our study offered tentative evidence that pain and depression impacted differently on the mental and physical aspect of QoL. As these findings were based on a Chinese teacher sample, future studies should employ more representative samples across cultures to verify the present data.

Figure 1: Standardized beta coefficient in pain partially mediated pathway from depression to QoL (mental). ** p < 0.005; *** p < 0.001.

Mentions: The results of Model 1 (Table 2) showed a significant inverse relationship between depression scores and mental QoL (β = -0.154, p < 0.05), whereas depression was positively related to pain (β = 0.271, p < 0.001). Pain was significantly and inversely related to QoL (β = -0.201, p < 0.001). When mediation was controlled, depression remained inversely associated with QoL (β = -0.111, p < 0.005), demonstrating a partial mediation effect of pain between depression and QoL. Sobel's test indicated pain's role as a mediator the depression-QoL relationship (z = -3.124, p < 0.005) (Figure 1).
