Predictive Model of Psychological Distress in Patients With Lung Cancer: A Cross-sectional Study

Association between personality traits and psychological distress among postmenopausal women with coronary heart disease: A cross-sectional survey and mediation analysis

Postmenopausal women with negative personality characteristics are at an increased risk of psychological disorders, yet little is known about the mechanism underlying the relationship between type D personality and psychological distress in postmenopausal women with coronary disease. This study assessed the mediating roles of perceived social support and self-perceived burden in the relationship between type D and psychological distress based on the equity theory and stress-buffering model. Demographic characteristics, type D, psychological distress, perceived social support, and self-perceived burden were completed by 335 participants with self-reported questionnaires using a cross-sectional design in Southeast China. The results revealed that perceived social support and self-perceived burden both separately and serially mediated the relationship between type D personality and psychological distress. Effective intervention strategies aimed at improving perceived social support or reducing self-perceived burden may be beneficial in reducing psychological distress.

Influence of initial check, information exchange, final accuracy check, reaction information nursing on the psychology of elderly with lung cancer

BACKGROUND

As one of the fatal diseases with high incidence, lung cancer has seriously endangered public health and safety. Elderly patients usually have poor self-care and are more likely to show a series of psychological problems.

AIM

To investigate the effectiveness of the initial check, information exchange, final accuracy check, reaction (IIFAR) information care model on the mental health status of elderly patients with lung cancer.

METHODS

This study is a single-centre study. We randomly recruited 60 elderly patients with lung cancer who attended our hospital from January 2021 to January 2022. These elderly patients with lung cancer were randomly divided into two groups, with the control group taking the conventional propaganda and education and the observation group taking the IIFAR information care model based on the conventional care protocol. The differences in psychological distress, anxiety and depression, life quality, fatigue, and the locus of control in psychology were compared between these two groups, and the causes of psychological distress were analyzed.

RESULTS

After the intervention, Distress Thermometer, Hospital Anxiety and Depression Scale (HADS) for anxiety and the HADS for depression, Revised Piper's Fatigue Scale, and Chance Health Locus of Control scores were lower in the observation group compared to the pre-intervention period in the same group and were significantly lower in the observation group compared to those of the control group (P < 0.05). After the intervention, Quality of Life Questionnaire Core 30 (QLQ-C30), Internal Health Locus of Control, and Powerful Others Health Locus of Control scores were significantly higher in the observation and the control groups compared to the pre-intervention period in their same group, and QLQ-C30 scores were significantly higher in the observation group compared to those of the control group (P < 0.05).

CONCLUSION

The IIFAR information care model can help elderly patients with lung cancer by reducing their anxiety and depression, psychological distress, and fatigue, improving their tendencies on the locus of control in psychology, and enhancing their life qualities.

Psychological distress as risk factor for the efficacy of whole-brain radiotherapy in brain metastasis patients

Aim: To evaluate the relationship between psychological distress and the efficacy of whole-brain radiotherapy (WBRT) in advanced brain metastasis patients. Methods: Brain metastasis patients (40 with psychological distress and 47 without psychological distress) completed distress thermometer tests before WBRT, and progression-free survival (PFS) was acquired during the follow-up period. Results: Psychological distress was a risk factor for poorer PFS in patients treated with WBRT (p < 0.01). The PFS of survivors who underwent WBRT was superior for those without psychological distress (hazard ratio: 0.295; 95% CI: 0.173-0.500; p < 0.01). Conclusion: The survival of brain metastasis patients receiving WBRT was influenced by psychological distress, which negatively affected the treatment outcome and is likely to be a potential risk indicator in advanced cancer patients receiving WBRT.

Efficacy and mechanisms of four-week MBSR on psychological distress in lung cancer patients: a single-center, single-blind, longitudinal, randomized controlled trial

Objective

This study aimed to evaluate the efficacy of a 4-week mindfulness-based stress reduction (MBSR) program on psychological distress in patients with lung cancer and elucidate its mechanisms.

Methods

This single-center, single-blinded, longitudinal, randomized controlled trial was conducted on 175 patients with lung cancer randomly allocated to a 4-week MBSR or a waiting-list group. The efficacy and mechanisms of the 4-week MBSR program were evaluated by outcome measures at preintervention (T0), the immediate postintervention (T1), 1 month (T2), and 3 months (T3). We analyzed the collected data using the per-protocol set principle, independent sample t-test, repeated measure analysis of variance, and structural equation modeling.

Results

The 4-week MBSR program significantly alleviated psychological distress (F ​= ​15.05, P ​< ​0.001), decreased perceived stigma (F ​= ​8.260, P ​= ​0.005), improved social support (F ​= ​16.465, P ​< ​0.001), and enhanced mindfulness (F ​= ​17.207, P ​< ​0.001) compared with usual care at T1, T2, and T3. All variables significantly changed over time except for copying style (P ​= ​0.250). The changes in social support, mindfulness, and perceived stigma mediated the efficacy of the 4-week MBSR program on psychological distress (β ​= ​−0.292, P ​= ​0.005; β ​= ​−0.358, P ​= ​0.005).

Conclusions

This study shows the benefits of the MBSR program for psychological distress, social support, mindfulness, and perceived stigma in patients with lung cancer. Also, it elucidates the mechanisms by which the MBSR program alleviates psychological distress by improving social support, enhancing mindfulness, and decreasing perceived stigma. The findings provide insights into applying the MBSR program to reduce psychological distress among patients with lung cancer.

Social Support and Meaning of Life in Women with Breast Cancer

Background

Social support is known as an affection-oriented coping mechanism when a person is involved with cancer. Therefore, this study was conducted to investigate the relationship between family social support and the meaning of life in women with breast cancer.

Methods

In this cross-sectional study, 84 women with a mean age of 60 (SD = 5.7) years with breast cancer who were admitted to a teaching hospital participated. Data were collected using social support and meaning of life questionnaires. After collecting the completed questionnaires and entering the data into the computer, the analysis was performed using SPSS software and using t-test, ANOVA, and Pearson correlation test at a significant level of 0.01.

Results

The mean score of their social support was 39.35 ± 9.51, respectively and the meaning of life was 29.5 ± 7.49. ANOVA results indicated that the social support score and meaning of life had no significant relationship with any of the demographic variables. Also, the findings suggest that there is a statistically significant correlation between social support and the meaning of life (r = 0.773, P < 0.001).

Conclusion

It is proposed to increase the level of social support from the family to help improve the meaning of life in cancer patients.

Association between Type-D Personality and Affective (Anxiety, Depression, Post-traumatic Stress) Symptoms and Maladaptive Coping in Breast Cancer Patients: A Longitudinal Study

Background:

Type-D (distressed) personality has not been prospectively explored for its association with psychosocial distress symptoms in breast cancer patients.

Objective:

The objective of the study was to test the hypothesis that Type-D personality can be associated with psychosocial distress variables in cancer over a 2-point period (6 month-follow-up).

Aims:

The aim of the study was to analyze the role of Type-D personality in relation to anxiety, depression, post-traumatic stress symptoms, general distress, and maladaptive coping among cancer patients.

Methods:

145 breast cancer patients were assessed within 6 months from diagnosis (T0) and again 6 months later (T1). The Type-D personality Scale, the Hospital Anxiety and Depression Scale, Depression subscale (HAD-D), the Brief Symptom Inventory (BSI-18) Anxiety subscale, the Distress Thermometer (DT), the Post-traumatic Symptoms (PTS) Impact of Event Scale (IES), and the Mini Mental Adjustment to Cancer (Mini-MAC) Anxious Preoccupation and Hopelessness scales were individually administered at T0 and T1.

Results:

One-quarter of cancer patients met the criteria for Type-D personality, which was stable over the follow-up time. The two main constructs of Type-D personality, namely social inhibition (SI) and negative affectivity (NA), were related to anxiety, depression, PTS, BSI-general distress and maladaptive coping (Mini-MAC anxious preoccupation and hopelessness). In regression analysis, Type-D SI was the most significant factor associated with the above-mentioned psychosocial variables, both at T0 and T1.

Conclusion:

Likewise other medical disorders (especially cardiology), Type-D personality has been confirmed to be a construct significantly related to psychosocial distress conditions and maladaptive coping that are usually part of assessment and intervention in cancer care. More attention to personality issues is important in oncology.

Predicting the Risk of Psychological Distress among Lung Cancer Patients: Development and Validation of a Predictive Algorithm Based on Sociodemographic and Clinical Factors

Objective

Lung cancer patients reported the highest incidence of psychological distress. It is extremely important to identify which patients at high risk for psychological distress. The study aims to develop and validate a predictive algorithm to identify lung cancer patients at high risk for psychological distress.

Methods

This cross-sectional study identified the risk factors of psychological distress in lung cancer patients. Data on sociodemographic and clinical variables were collected from September 2018 to August 2019. Structural equation model (SEM) was conducted to determine the associations between all factors and psychological distress, and then construct a predictive algorithm. Coincidence rate was also calculated to validate this predictive algorithm.

Results

Total 441 participants sent back validated questionnaires. After performing SEM analysis, educational level (β = 0.151, P = 0.004), residence (β = 0.146, P = 0.016), metastasis (β = 0.136, P = 0.023), pain degree (β = 0.133, P = 0.005), family history (β = -0.107, P = 0.021), and tumor, node, and metastasis stage (β = -0.236, P < 0.001) were independent predictors for psychological distress. The model built with these predictors showed an area under the curve of 0.693. A cutoff of 66 predicted clinically significant psychological distress with a sensitivity, specificity, positive predictive value, and negative predictive value of 65.41%, 66.90%, 28.33%, and 89.67%, respectively. The coincidence rate between predictive algorithm and distress thermometer was 64.63%.

Conclusions

A validated, easy-to-use predictive algorithm was developed in this study, which can be used to identify patients at high risk of psychological distress with moderate accuracy.

The positive effect of social support on psychological distress among Chinese lung cancer patients: The mediating role of self-esteem

AIM

To investigate the effect of social support on psychological distress among Chinese lung cancer patients and clarify the mediating role of self-esteem.

DESIGN

A cross-sectional descriptive correlational survey of 441 Chinese lung cancer patients was designed.

METHODS

Self-esteem was supposed to play a mediating role in the association between social support and psychological distress. We collected demographic information, the Distress Thermometer, Multidimensional Scale of Perceived Social Support and Rosenberg Self-Esteem Scale.

RESULTS

Our revised model demonstrated an acceptable fit to the data (χ²  = 37.489, comparative fit index (CFI) = 0.965, Tucker-Lewis index (TLI) = 0.926, root mean square error of approximation [RMSEA] = 0.099). Social support had a direct effect on self-esteem and psychological distress, and self-esteem had also a direct effect on psychological distress. Meanwhile, self-esteem also partially mediated the relationship between social support and psychological distress among Chinese lung cancer patients.
