Anxiety,depression, and health-related quality of life in aging people living with HIV compared to diabetes patients and patients with minor health conditions: a longitudinal study

HIV infection has evolved from a fatal to a treatable condition, leading to an increase in the rate of elderly People Living with HIV (PLWH). However, little is known about the psychosocial burden of elderly PLWH. Thus, the aim of this longitudinal multi-center cohort study was to investigate whether elderly PLWH experience more anxiety and depression and reduced health related quality of life (HRQOL) compared to elderly patients with other chronic conditions. PLWH were compared to diabetes patients (DM) and patients with minor health conditions (MHC), e.g. patients with hypertension or allergic conditions. All patients were over 50 years old. Anxiety and depression (HADS) as well as HRQOL (SF-36) were assessed at baseline and after 12 months. 218 PLWH, 249 DM and 254 MHC were included. At baseline, the study groups did not differ in anxiety, depression, and physical HRQOL. However, PLWH indicated lower mental HRQOL than DM and MHC patients (p = 0.001). We did not obtain any moderating effects showing a differential effect of patient characteristics on anxiety, depression, and HRQOL in the three patient groups. At follow-up, the level of anxiety, depression, and HRQOL did not change significantly. The prevalence of anxiety ranged between 27 and 35%, and that of depression between 17 and 28%. Thus, the results of our investigation tentatively suggest that the psychosocial adaptation to HIV among elderly PLWH resembles those of other chronic diseases. There may be some subtle impairments, though, as PLWH experienced lower mental HRQOL.     

“Behave like a responsible adult” – Relation between social identity and psychosocial skills at stake in self-management of a chronic disease

We show that the development of psychosocial skills promoting self-management of a chronic disease is associated with the acquisition of a social identity valued in the ideological context of reference. To do this, we focus on a skill that is important for people suffering from a chronic disease to acquire: Assuming responsibility for self-managing one’s own pathology. Because acting responsibly is also a skill socially attributed to the identity of adults in Western liberal societies, we studied the chronically ill’s sense of belonging to the adult social group. In Study 1 (N = 102 diabetics), we suggested that behaving like a “responsible adult” in the self-management of a chronic disease is socially valued. In Study 2 (N = 261 diabetics), we suggested that identification with this group is associated with a feeling of responsibility promoting improved self-management behaviors. The results obtained from the two studies are consistent with our hypotheses. They allow us to conceptualize psychosocial skills through the identity, ideological and normative issues that underpin their development.     

Developing human-machine trust: Impacts of prior instruction and automation failure on driver trust in partially automated vehicles

To prompt the use of driving automation in an appropriate and safe manner, system designers require knowledge about the dynamics of driver trust. To enhance this knowledge, this study manipulated prior information of a partial driving automation into two types (detailed and less) and investigated the effects of the information on the development of trust with respect to three trust attributions proposed by Muir (1994): predictability, dependability, and faith. Furthermore, a driving simulator generated two types of automation failures (limitation and malfunction), and at six instances during the study, 56 drivers completed questionnaires about their levels of trust in the automation. Statistical analysis found that trust ratings of automation steadily increased with the experience of simulation regardless of the drivers’ levels of knowledge. Automation failure led to a temporary decrease in trust ratings; however, the trust was rebuilt by a subsequent experience of flawless automation. Results showed that dependability was the most dominant belief of drivers’ trust throughout the whole experiment, regardless of their knowledge level. Interestingly, detailed analysis indicated that trust can be accounted by different attributions depending on the drivers’ circumstances: the subsequent experience of error-free automation after the exposure to automation failure led predictability to be a secondary predictive attribution of drivers’ trust in the detailed group whilst faith was consistently the secondary contributor to shaping trust in the less group throughout the experiment. These findings have implications for system design regarding transparency and for training methods and instruction aimed at improving driving safety in traffic environments with automated vehicles.

The influence of different dialysis modalities on the quality of life of patients with end-stage renal disease: A systematic literature review

Objectives: This study aims to generate evidence regarding the relationships of different dialysis modalities with HR-QOL.

Design: A systematic review was conducted to investigate the HR-QOL of patients treated with different dialysis modalities.

Methods: A literature search was conducted for English language articles in the CINAHL, Medline and PubMed databases published from January 1990 through May 2016. Specifically, we sought articles that would compare the HR-QOL of hemodialysis (HD) and peritoneal dialysis (PD) patients in terms of physiological, psychological and social functioning, as well as disease symptoms. Thirty-four articles met the study inclusion criteria and were included into the analysis.

Results: The research results indicated no significant differences in HR-QOL between HD and PD treatment. However, a higher percentage of patients who received PD had a better HR-QOL in terms of physiological, psychological, social and disease symptoms.

Conclusions: Despite the fact that the results of this study showed no difference in HR-QOL between HD and PD treatment, its review of relevant references can serve as a reference for health professionals. However, patients’ conditions must still be taken into account when making suggestions about which dialysis modality a patient should use.     

Psychological predictors for health-related quality of life and disability in persons with chronic obstructive pulmonary disease (COPD)

Objective: Individuals with chronic obstructive pulmonary disease (COPD) exhibit low physical and mental health-related quality of life (HRQL) and high susceptibility to disability. We investigated the influence of psychological factors on HRQL and disability in COPD individuals recruited from the general population. In line with Leventhal’s common sense model, we expected psychological factors to be associated with HRQL and disability even after controlling for medical status.

Methods: Individuals with COPD (n = 502; 59.7 years old; GOLD grades were I: 3%, II: 17%, III: 34%, IV: 46%) were assessed through an online survey administered via COPD patient organisations in Germany. Individuals filled in the Short Form Health Survey (SF-12), COPD Assessment Test, Patient Health Questionnaire (modules: GAD-2, PHQ-15, PHQ-9), Brief Illness Perception Questionnaire, a questionnaire that assesses causal illness attributions, and the internal illness-related locus of control scale of the ‘KKG questionnaire for the assessment of control beliefs about illness and health’. Multiple linear regressions were calculated.

Results: The investigated factors explained high variances (disability = 56%, physical HRQL = 28%, mental HRQL = 63%, p ≤ .001). Better mental health, more optimistic illness perceptions, attribution to psychological causes, and stronger internal locus of control were associated with lower disability and better HRQL. Comorbid somatic symptoms contributed to high disability and low quality of life.

Conclusion: Psychological factors, such as illness perception, attribution and internal locus of control, were associated with disability and HRQL. These factors should be considered when designing treatments for individuals with COPD, and adequate interventions should be provided to enhance illness understanding and self-management skills.     

Pathways maintaining physical health problems from childhood to young adulthood: The role of stress and mood

Objective: Poor physical health in childhood is associated with a variety of negative health-related outcomes in adulthood. Psychosocial pathways contributing to the maintenance of physical health problems from childhood to young adulthood remain largely unexamined, despite evidence that factors such as negative mood and stress impact physical health.

Design: The current study tested the direct and indirect effects of ongoing health, chronic stress, health-related chronic stress, and depressive symptoms at age 20 on the link between health problems in childhood and young adulthood (age 21) in a longitudinal sample (n = 384).

Main Outcome Measures: The hypotheses were tested using a multiple mediation path analysis framework; the primary outcome measure was a composite index of health status markers in young adulthood.

Results: The proposed model provided an adequate fit for the data, with significant total indirect effects of the four mediators and significant specific indirect effects of health-related chronic stress and depressive symptoms in maintaining health problems from childhood into young adulthood.

Conclusions: Health problems are maintained from early childhood into young adulthood in part through psychosocial mechanisms. Depressive symptoms and health-related chronic stress have significant, unique effects on the relationship between health problems in early childhood and young adulthood.     

Posttraumatic stress and depression: potential pathways to disease burden among heart failure patients

Background and Objectives: Posttraumatic stress disorder (PTSD) and Major Depressive Disorder (MDD) are associated with high disease burden. Pathways by which PTSD and MDD contribute to disease burden are not understood. Design: Path analysis was used to examine pathways between PTSD symptoms, MDD symptoms, and disease burden among 251 low-income heart failure patients. Methods: In Model 1, we explored the independent relationship between PTSD and MDD symptoms on disease burden. In Model 2, we examined the association of PTSD symptoms and disease burden on MDD symptoms. We also examined indirect associations of PTSD symptoms on MDD symptoms, mediated by disease burden, and of PTSD symptoms on disease burden mediated by MDD symptoms. Results: Disease burden correlated with PTSD symptoms (r = .41; p < .001) and MDD symptoms (r = .43; p < .001) symptoms. Both models fit the data well and displayed comparable fit. MDD symptoms did not mediate the association of PTSD symptoms with disease burden. Disease burden did mediate the relationship between PTSD symptoms and MDD symptoms. Conclusions: Results support the importance of detection of PTSD in individuals with disease. Results also provide preliminary models for testing longitudinal data in future studies.     

Coping strategies of mother carers of children living with chronic illness and disease in a rural South African community

The present study explored the coping strategies used by mother carers of children living with chronic illness and disease (CID) in a rural South African community. Ten mothers (age range = 30 to 56 years) were selected through snowball sampling to participate in the present study. They provided care to their children, a majority (50%) of whom had epilepsy, followed by asthma (20%) and other conditions. Data on the coping strategies used by mothers of children living with CID were collected using semi-structured interviews and analysed thematically. The results showed that mother carers tended to use three types of coping strategies, namely: appraisal-focused, problem-focused and emotion-focused strategies. Appraisal-focused was commonly used by mother carers whose children had epilepsy, whilst mother carers of children with asthma tended to use problem-focused coping strategies. All mother carers were found to use emotion-focused strategies to varying degrees in coping with the chronic diseases of their children.
