Life event stress and chronic obstructive pulmonary disease (COPD): associations with mental well-being and quality of life in a population-based study.

ABSTRACT:

Objectives

To investigate whether life event stress was associated with greater psychological distress and poorer quality of life in older individuals with chronic obstructive pulmonary disease (COPD), in comparison with their counterparts without COPD.

Design

Cross-sectional study.

Participants

A population-based sample (N=497) of individuals aged 65 and above with COPD (postbronchodilatation FEV1/FVC<0.70, N=136) and without COPD (N=277).

Measurements

We measured life event stress, depressive symptoms (GDS, Geriatric Depression Scale), cognitive symptoms and function (CFQ, Cognitive Failures Questionnaire and MMSE, Mini-Mental State Examination), and physical and mental health functional status (SF36-PCS, Physical Health Component Summary and SF36-MCS, Mental Health Component Summary) in participants with and without COPD.

Results

In two-way analysis of variance controlling for potential confounders, life event stress was associated with significant main effects of worse GDS (p<0.001), SF36-PCS (p=0.008) and SF36-MCS scores (p<0.001), and with significant interaction effects on GDS score (p<0.001), SF36-PCS (p=0.045) and SF36-MCS (p=0.034) in participants with COPD, more than in non-COPD participants. The main effect of COPD was found for postbronchodilator FEV1 (p<0.001) and cognitive symptoms (p=0.02).

Conclusions

Our findings indicate that life event stress was associated with more depressive symptoms and worse quality of life in individuals with COPD, much more than in those without COPD. Further studies should explore the role of cognitive appraisal of stress, coping resources and psycho-social support in this relationship.

Project description:BackgroundConversational user interfaces, or chatbots, are becoming more popular in the realm of digital health and well-being. While many studies focus on measuring the cause or effect of a digital intervention on people's health and well-being (outcomes), there is a need to understand how users really engage and use a digital intervention in the real world.ObjectiveIn this study, we examine the user logs of a mental well-being chatbot called ChatPal, which is based on the concept of positive psychology. The aim of this research is to analyze the log data from the chatbot to provide insight into usage patterns, the different types of users using clustering, and associations between the usage of the app's features.MethodsLog data from ChatPal was analyzed to explore usage. A number of user characteristics including user tenure, unique days, mood logs recorded, conversations accessed, and total number of interactions were used with k-means clustering to identify user archetypes. Association rule mining was used to explore links between conversations.ResultsChatPal log data revealed 579 individuals older than 18 years used the app with most users being female (n=387, 67%). User interactions peaked around breakfast, lunchtime, and early evening. Clustering revealed 3 groups including "abandoning users" (n=473), "sporadic users" (n=93), and "frequent transient users" (n=13). Each cluster had distinct usage characteristics, and the features were significantly different (P<.001) across each group. While all conversations within the chatbot were accessed at least once by users, the "treat yourself like a friend" conversation was the most popular, which was accessed by 29% (n=168) of users. However, only 11.7% (n=68) of users repeated this exercise more than once. Analysis of transitions between conversations revealed strong links between "treat yourself like a friend," "soothing touch," and "thoughts diary" among others. Association rule mining confirmed these 3 conversations as having the strongest linkages and suggested other associations between the co-use of chatbot features.ConclusionsThis study has provided insight into the types of people using the ChatPal chatbot, patterns of use, and associations between the usage of the app's features, which can be used to further develop the app by considering the features most accessed by users.

Project description:BackgroundSexual function is often affected in patients suffering from chronic diseases especially chronic obstructive pulmonary disease (COPD). However, the effect of COPD on sexual satisfaction is underappreciated in clinical practice. The aim of this study is to evaluate the impact of COPD on patient's sexuality and the explanatory variables of sexual dissatisfaction.MethodsQuestionnaires were emailed to participants and they submitted their responses on the Santé Respiratoire France website. Data about sexual well-being (Arizona Sexual Experience Scale, ASEX), Quality of life (VQ11), anxiety, depression (Hospitalized anxiety and depression, HAD) and self-declared COPD grade were collected.ResultsSeven hundred and fifty one subjects were included and were characterized as follows: women-51%, mean age-61 years, in a couple-62% and 70%-retired. Every grade of COPD was represented. Out of 751 participants, 301 participants (40%) had no sexual activity and 450 (60%) had sexual activity. From the 450 participants, 60% needed to change their sexual life because of their disease (rhythm, frequency and position). Subjects often used medications to improve sexual performance (43% used short-acting bronchodilator and 13% -specific erectile dysfunction drugs). ASEX questionnaire confirmed patients' dissatisfaction (diminution of sexual appetite for 68% and sexual desire for 60%) because of breathlessness and fatigue. Eighty one percent of the responders had an altered quality of life (VQ11 mean score 35) and frequent suspected anxiety or depression (HAD mean score 10.8). Ninety percent declared that sexual dysfunction had never been discussed by their doctors, while 36% of patients would have preferred to undergo a specialized consultation.ConclusionSexual dysfunction is frequent among COPD patients and leads to an altered well-being, however being a cultural taboo, it remains frequently neglected. Sexual guidance should be a part of patient's consultations improve quality of sexual life.

Project description:IntroductionChronic obstructive pulmonary disease (COPD) is responsible for 2.9 million deaths annually in Europe. Symptom burden and functional decline rise as patients reach advanced stages of the disease enhancing risk of vulnerability and dependency on informal caregivers (ICs).Evidence shows that hope is an important psycho-social-spiritual construct that humans use to cope with symptom burden and adversity. Hope is associated with increased quality of life (QoL) comfort and well-being for patients and ICs. A better understanding of the meaning and experience of hope over time as patients transition through chronic illness may help healthcare professionals to plan and deliver care more appropriately.Methods and analysisThis is a longitudinal multicentre mixed-methods study with a convergent design. Quantitative and qualitative data will be collected from dyads of advanced COPD patients and their ICs in two university hospitals at two points in time. The Herth Hope Index, WHO Quality of Life BREF, Functional Assessment of Chronic Illness Therapy-Spiritual Well-being and the French version of the Edmonton Symptom Assessment Scale will be used to collect data. Dyadic interviews will be conducted using a semi-structured interview guide with five questions about hope and their relationship with QoL.Statistical analysis of data will be carried out using R V.4.1.0. To test whether our theoretical model as a whole is supported by the data, structural equation modelling will be used. The comparison between T1 and T2 for level of hope, symptom burden, QoL and spiritual well-being, will be carried out using paired t-tests. The association between symptom burden, QoL, spiritual well-being and hope will be tested using Pearson correlation.Ethics and disseminationThis study protocol received ethical approval on 24 May 2022 from the Commission cantonale d'éthique de la recherche sur l'être humain-Canton of Vaud. The identification number is 2021-02477.
