The role of social support and self-esteem in the presence and course of depressive symptoms: a comparison of cancer patients and individuals from the general population

The key focus of this longitudinal study in the Netherlands was to determine the role of social support (i.e. perceived availability of emotional support, lack of received problem-focused emotional support, and negative interactions) and positive and negative self-esteem in depressive symptoms in 475 recently diagnosed cancer patients and 255 individuals without cancer from the general population. Patients and the comparison group were interviewed and filled in a questionnaire at two points in time: 3 months (T1) and 15 months (T2) after diagnosis. The results indicated that social support and self-esteem were weakly to moderately related to each other. Negative self-esteem was more strongly related to all three types of social support, compared to positive self-esteem. Regression analyses showed that social support and self-esteem were independently related to depressive symptoms (concurrently), such that lower levels of social support and self-esteem were strongly associated with higher levels of depressive symptoms. This finding suggests that these two resources supplement each other additively. A longitudinal analysis showed that social support and self-esteem also predicted future levels of depressive symptoms, although the explained variance was much lower than in a cross-sectional analysis. Comparisons between cancer patients and the comparison group generally revealed no significant differences between the two groups in the associations of social support and self-esteem with depressive symptoms. The only exception was a lack of problem-focused emotional support. At three months after diagnosis, a lack of this type of support, characterised by reassuring, comforting, problem-solving, and advice, was more strongly related to depressive symptoms in patients than in the comparison group.

Depressive symptoms in cancer patients compared with people from the general population: the role of sociodemographic and medical factors

This study examined depressive symptoms in 475 patients with cancer and in a reference group of 255 individuals without cancer from the general population and the associations of those symptoms with sociodemographic and medical factors. Depressive symptoms were measured at 3 months (Time 1) and 15 months (Time 2) after diagnosis. Patients reported more depressive symptoms than the reference group did at Times 1 and 2. Younger age, especially, was related to the onset of depressive symptoms after a cancer diagnosis. Better-educated patients and those with a lower stage of disease reported a greater decrease in depressive symptoms over time. The authors conclude that certain sociodemographic factors may primarily reflect general dysfunction or vulnerability rather than risk factors for developing depressive symptoms after a diagnosis of cancer. < copyright > 2003 by The Haworth Press, Inc.

The evaluation of the Center for Epidemiologic Studies Depression (CES-D) scale: depressed and positive affect in cancer patients and healthy reference subjects

This study examined the reliability and validity of a two-factor structure of the Center for Epidemiologic Studies Depression (CES-D) scale. The study was conducted in a large group of cancer patients (n = 475) and a matched reference group (n = 255). Both groups filled in a questionnaire at two points in time: patients 3 and 15 months after diagnosis. Factor analysis confirmed our hypothesis that the 16 negatively and four positively formulated items measure two relatively independent factors, i.e. Depressed Affect and Positive Affect. Therefore, these items should not be combined into an overall sumscore. In both groups, Depressed Affect proved to be a reliable and valid measure of depressive symptomatology, as indicated by its good internal consistency, its strong correlations with other measures of psychological distress and neuroticism, and its effectiveness in discriminating patients from the reference group on depressive symptomatology. In contrast, the validity of the Positive Affect factor could not be confirmed, since it was only weakly related to other measures of psychological distress and extraversion. Depressed and Positive Affect were about equally related to self-esteem, life satisfaction, and quality of life. These findings support the use of a sumscore based on the 16 negatively formulated CES-D items as a more valid measure of depressive symptomatology, in cancer patients and in healthy individuals from the general population
