The Transition From Victim to Victor: Application of the Theory of Mastery

The impact of life stress, psychological resources, and proactive behaviors on quality of life among people living with HIV

OBJECTIVES

Quality of life (QoL) is an important consideration for people living with HIV (PWH). We investigated the relationship between stress, psychological resources, and proactive behaviors, on QoL (conceptualized as life satisfaction, successful aging, and depressive symptoms) by testing the hypotheses: (1) greater life stress (stress and functional impairment) is associated with poorer QoL; (2) resources (mastery, resilience, and social support) are associated with better QoL, beyond the influence of stress; and (3) proactive behaviors (medication management and leisure activities) mediate the relationship between resources and QoL.

METHODS

Secondary analyses were performed (N = 128 PWH). Participants' mean age was 52.3, 83.6% were male, and 53.9 identified as white. Multivariate regressions were performed within the context of path analyses.

RESULTS

In series 1, greater stress was associated with poorer life satisfaction (p < 0.001), lower self-rated successful aging (p < 0.001), and greater depression (p < 0.001). Functional impairment was associated with lower successful aging (p = 0.017) and greater depression (p = 0.001). In series 2, which accounted for mastery, resilience, social support, as well as demographic covariates, mastery was associated with greater life satisfaction (p = 0.038). In series 3, stress, functional impairment, leisure activities, and ART management were added to the model and social support was associated with engagement in leisure activities (p < 0.001), which was associated with better successful aging (p = 0.006). Fit indices suggested adequate relative fit. In bootstrapped analyses of indirect effects, social support was indirectly associated with successful aging through leisure activities (p = 0.020).

CONCLUSIONS

QoL, as captured by self-rated successful aging, is threatened by stress but positively influenced by social support and engaging in leisure activities. Findings support a model of proactive successful aging for PWH.

A Middle-Range Theory for Diabetes Self-management Mastery

Diabetes mellitus is the seventh leading cause of death in America and affects 382 million people worldwide. Individuals with diabetes must manage the complexity of the disease, its treatment, and complications to avert deleterious consequences associated with the illness. However, not all patients with diabetes successfully gain mastery to positively impact self-management. A new middle-range theory is proposed that merges 2 extant theories, theory of mastery and organismic integration theory, to better understand this human response. The theories' philosophical, theoretical, and conceptual perspectives were examined and relational properties synthesized to provide a conceptual representation of the phenomenon of interest.

Community-based services for homeless adults experiencing concurrent mental health and substance use disorders: a realist approach to synthesizing evidence

Consultations with community-based service providers in Toronto identified a lack of strong research evidence about successful community-based interventions that address the needs of homeless clients experiencing concurrent mental health and substance use disorders. We undertook a collaborative research effort between academic-based and community-based partners to conduct a systematic evidence synthesis drawing heavily from Pawson's realist review methodology to focus on both whether programs are successful and why and how they lead to improved outcomes. We examined scholarly and nonscholarly literature to explore program approaches and program elements that lead to improvements in mental health and substance use disorders among homeless individuals with concurrent disorders (CD). Information related to program contexts, elements, and successes and failures were extracted and further supplemented by key informant interviews and author communication regarding reviewed published studies. From the ten programs that we reviewed, we identified six important and promising program strategies that reduce mental health and, to a far lesser degree, substance use problems: client choice in treatment decision-making, positive interpersonal relationships between client and provider, assertive community treatment approaches, providing supportive housing, providing supports for instrumental needs, and nonrestrictive program approaches. These promising program strategies function, in part, by promoting and supporting autonomy among homeless adults experiencing CD. Our realist informed review is a useful methodology for synthesizing complex programming information on community-based interventions.

Maintaining hope in transition: a theoretical framework to guide interventions for people with heart failure

Theoretical frameworks provide a structure for the planning and delivery of nursing care and for research. Heart failure (HF), a condition of increasing prevalence in communities internationally, is responsible for high rates of morbidity, mortality, and great societal burden. The HF illness trajectory can be unpredictable and uncertain. Markers of transition, such as functional decline and increasing dependence, can signal the need for transition to a more palliative approach. This transition challenges clinicians to deliver information and interventions and to support patients and their families not only in relation to their physical status but also in the social, psychological, and existential dimensions. This article describes a theoretical framework, Maintaining Hope in Transition, informed by transition theory, to assist patients to cope with a diagnosis of HF and to guide development of nursing interventions. Transition theory provides a useful context to assist clinicians, patients, and their families adjust to the challenges inherent in a diagnosis of HF and negotiating the illness trajectory. Key factors acknowledged in the Maintaining Hope in Transition framework that determine its utility in models of care for HF patients are (1) acknowledging the changing of life circumstances, (2) restructuring reality, (3) dealing with vulnerability, (4) achieving normalization, and (5) resolving uncertainty. It is likely that incorporation of these factors in care planning, information, and interventions can facilitate patients' and their families' abilities to negotiate the HF illness trajectory, particularly in the advanced stages.

Transition: a literature review

AIM

This paper reports a comprehensive literature review exploring how the term 'transition' has been used in the health literature.

BACKGROUND

The meaning of transition has varied with the context in which the term has been used. The last 3 decades have seen altered understandings in the concept of transition in the social science and health disciplines, with nurses contributing to more recent understandings of the transition process as it relates to life and health.

METHOD

The CINAHL, Medline, Sociofile and Psychlit databases were accessed and papers published between 1994 and 2004 were retrieved to answer the questions 'How is the word transition used?' and 'What is the concept of transition informing?' Transition theoretical frameworks were also explored.

FINDINGS

Widespread use of the word 'transition' suggests that it is an important concept. Transitional definitions alter according to the disciplinary focus, but most agree that transition involves people's responses during a passage of change. Transition occurs over time and entails change and adaptation, for example developmental, personal, relational, situational, societal or environmental change, but not all change engages transition. Reconstruction of a valued self-identity is essential to transition. Time is an essential element in transition and therefore longitudinal studies are required to explore the initial phase, midcourse experience and outcome of the transition experience.

CONCLUSION

Transition is the way people respond to change over time. People undergo transition when they need to adapt to new situations or circumstances in order to incorporate the change event into their lives. Transition is a concept that is important to nursing; however, to further develop understandings, research must extend beyond single events or single responses. Longitudinal comparative and longitudinal cross-sectional inquiries are required to further develop the concept.
