Differential associations between perceived and objective measurement of distress tolerance in relation to antiretroviral treatment adherence and response among HIV-positive individuals

Psychological predictors of treatment adherence among patients with diabetes (types I and II): Modified information-motivation-behavioural skills model

Non-adherence to medical regimens among patients with diabetes is a well-recognized concern in health care. Modified information, motivation, behavioural skills (IMB) model by adding an emotion component to it was tested to explore predictors of treatment adherence among 1,125 Iranian patients with diabetes type I (T1D) and type II (T2D) and due to other medical conditions. The modified IMB model explained 35% of the treatment adherence with large effect-sizes f²  = 0.56 to 0.69. Self-compassion and interpersonal communication between staff and patients (ICSP) were significant predictors of treatment adherence among patients with T1D, T2D and diabetes due to other medical conditions, while both outperformed the other significant predictors of treatment adherence, i.e., illness perception and social support in all groups. Distress intolerance was a significant predictor of treatment adherence only in patients with T2D. In addition, patients, based on their type of diabetes, exhibited different patterns of illness perception in predicting treatment adherence. Among T2D patients and those with diabetes due to other medical conditions, gender (male; only in T2D) and being single were significant predictors of treatment adherence, while age and diabetes duration were not. Finally, the model demonstrated that above and beyond demographic features, self-compassion, interpersonal communication between patients and health care staff, distress intolerance, perceived social support and illness perception were significant predictors of treatment adherence among patients with diabetes.

Exploring Distress Tolerance as an Underlying Mechanism in the Relation Between Negative Affectivity and Anxiety/Depression Among Persons Living with HIV/AIDS

Persons living with HIV/AIDS (PLHIV) suffer disproportionately from a variety of mood disorders relative to the general population, yet, there is little understanding of the underlying nature behind this. The present study explored the indirect effect of perceived distress tolerance in relation between negative affectivity and anxiety/depressive symptoms and disorders among PLHIV. Participants included 97 PLHIV (60.8% male; 66% Minority; M _age = 48.5 years, SE = 7.7). Results revealed indirect effects of negative affectivity via perceived distress tolerance in relation to social anxiety, depression symptoms, as well as the existence of any anxiety disorder; findings were evident after controlling for covariates. Perceived distress tolerance may serve as a construct to aid understanding in the relation between negative affectivity and the expression of anxiety/depressive symptoms and disorders among PLHIV. Future work may consider addressing distress tolerance in efforts to offset the severity of the expression of anxiety/depressive symptoms among PLHIV.

Distress Tolerance Intervention for Improving Self-Management of Chronic Conditions: A Systematic Review

BACKGROUND

The inability to tolerate distress can negatively influence effective self-management (SM) of chronic conditions by interfering with the ability to focus on illness needs and impairing problem-solving and prioritizing capabilities, as well as engagement in SM activities. Interventions to increase distress tolerance offer a holistic approach to chronic disease SM and may enhance the individual's ability to apply SM skills and resources to improve quality of life and overall health. The purpose of this systematic review was to deepen understanding of the relationships among distress tolerance and goal-oriented problem-solving as an aspect of chronic disease SM.

METHOD

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations were used to develop a search strategy, selection criteria, screening, and identification and extraction procedures. PubMed, CINAHL, PsychInfo, and Scopus were searched from 2006 to December 2017 using the following search terms: distress tolerance, chronic conditions, self-management.

RESULTS

Across the 11 studies included in the literature review, there was a high level of heterogeneity in the use of subjective and objective measures to assess distress tolerance, and only one study included instruments to measure goal-oriented problem-solving, the target of distress tolerance interventions that are assumed to influence the selected health outcome.

CONCLUSION

Further research is needed on the efficacy of distress tolerance interventions for improving SM of chronic conditions. Theory-driven interventions that explicate the precise goal-oriented problem-solving and SM behaviors that are expected to change as a result of the distress tolerance intervention will provide insight on the efficacy of the intervention and help close the theory-practice gap.

Psychological model of ART adherence behaviors in persons living with HIV/AIDS in Mexico: a structural equation analysis

OBJECTIVE

The objective of this study has been to test the ability of variables of a psychological model to predict antiretroviral therapy medication adherence behavior.

METHODS

We have conducted a cross-sectional study among 172 persons living with HIV/AIDS (PLWHA), who completed four self-administered assessments: 1) the Psychological Variables and Adherence Behaviors Questionnaire, 2) the Stress-Related Situation Scale to assess the variable of Personality, 3) The Zung Depression Scale, and 4) the Duke-UNC Functional Social Support Questionnaire. Structural equation modeling was used to construct a model to predict medication adherence behaviors.

RESULTS

Out of all the participants, 141 (82%) have been considered 100% adherent to antiretroviral therapy. Structural equation modeling has confirmed the direct effect that personality (decision-making and tolerance of frustration) has on motives to behave, or act accordingly, which was in turn directly related to medication adherence behaviors. In addition, these behaviors have had a direct and significant effect on viral load, as well as an indirect effect on CD4 cell count. The final model demonstrates the congruence between theory and data (x²/df. = 1.480, goodness of fit index = 0.97, adjusted goodness of fit index = 0.94, comparative fit index = 0.98, root mean square error of approximation = 0.05), accounting for 55.7% of the variance.

CONCLUSIONS

The results of this study support our theoretical model as a conceptual framework for the prediction of medication adherence behaviors in persons living with HIV/AIDS. Implications for designing, implementing, and evaluating intervention programs based on the model are to be discussed.

Meeting the complex needs of individuals living with HIV: a case study approach

This article critically discusses the nursing care and management of a person living with the human immunodeficiency virus (HIV) infection as a long-term condition, requiring highly complex HIV care. Complex HIV care is managed in the secondary care setting. However, recent legislation has motivated shifts in HIV care to the community care setting. This article aims to enhance health professionals' understanding in order to equip practice and district nurses to deliver HIV care provision. Antiretroviral adherence is a prerequisite for disease survival as well as an essential component of complete HIV self-care management. It is therefore imperative that nurses tailor adherence strategies according to each patient's requirements. Case management strategies such as the use of cognitive behavioural therapy to alleviate depressive symptoms will be considered. Furthermore, the use of motivational interviewing for antiretroviral adherence is highlighted as a potential intervention to help patients overcome the physical, psychological and physiological challenges of living with HIV-associated comorbidities. The delivery of integrated HIV care is pivotal for the management of the person living with HIV, as is the facilitation of a self-caring behaviour.

Antiretroviral treatment adherence as a mediating factor between psychosocial variables and HIV viral load

Psychosocial factors may directly impact HIV health measures such as viral load (VL) whether or not patients are taking antiretroviral treatment (ART) consistently. Structural equation modeling plus Baron and Kenny's (1986) four-step approach were used to test a mediated model predicting VL among 246 HIV-infected adults who were on ART. Exogenous variables were social support, barriers to adherence, and stress. Moderators were alcohol use, marijuana use, and neurocognitive impairment. A small positive association between marijuana use and ART adherence approached significance. Only barriers to adherence predicted a decrease in adherence rates and an increase in VL. No other factors were significantly associated with either VL or adherence, and no interaction effects between exogenous variables and moderators were identified. The association between barriers to adherence and VL was partially mediated by ART adherence. Findings provide modest support for a direct link between psychosocial variables and a virologic response to ART.
