Self-efficacy and self-management after stroke: a systematic review

Effects of a web-based stroke education program on recurrence prevention behaviors among stroke patients: a pilot study

The effectiveness of methods to prevent stroke recurrence and of education focusing on learners' needs has not been fully explored. The aims of this study were to assess the effects of such interventions among stroke patients and their primary caregivers and to evaluate the feasibility of a web-based stroke education program. The participants were 36 patients with a clinical diagnosis of ischemic stroke within 12 months post-stroke and their primary caregivers. The participants were randomly assigned to either an experimental or a control group. The primary measures included blood chemistry, self-reported health behaviors, sense of control, and health motivation for stroke patients, and caregiver mastery for caregivers. To test the feasibility of the intervention program, the rates of participation and occurrence of technical problems were calculated. The experimental group tended to improve significantly more than the control group in terms of exercise, diet, sense of control and health motivation for the stroke patients and in terms of caregiver mastery for the primary caregivers. The rate of participation in the web-based program was 63.1%. This program, which focuses on recurrence prevention in stroke patients and caregivers, has the potential to improve health behaviors for stroke patients.

Self-management in palliative medicine

PURPOSE OF REVIEW

Self-management in the palliative care domain means equipping patients and carers to manage medical aspects of illness, managing life roles and allowing adaptation to the changing dynamics brought on by illness and its progression. As well as dealing with the psychological consequences of living with a life-threatening illness in which the aim is to optimise living. This review will consider the rationale for developing and adopting self-management as a model of care.

RECENT FINDINGS

Health policy currently advocates de-investment in traditional approaches to patient management paralleled with a re-engineering of services towards approaches required to underpin self-management care. However, the literature suggests that patients lack a fundamental knowledge and more importantly an understanding of the progression of their illness or what palliative of hospice care is. As a first step, this issue must be addressed in any self-management intervention. In terms of outcomes evidence continues to emerge that when compared with care self-management imparts sustainable understanding in targeted areas and has the potential to create a preventive spend environment.

SUMMARY

The role of self-management in palliative care requires further elucidation yet based on the evidence which is predominately gleaned from long-term conditions it would seem sensible if not ethical to educate patients/carers to actively be involved in decision making.

From dictatorship to a reluctant democracy: stroke therapists talking about self-management

PURPOSE

Self-management is being increasingly promoted within chronic conditions including stroke. Concerns have been raised regarding professional ownership of some programmes, yet little is known of the professional's experience. This paper aims to present the views of trained therapists about the utility of a specific self-management approach in stroke rehabilitation.

METHOD

Eleven stroke therapists trained in the self-management approach participated in semi-structured interviews. These were audio recorded, transcribed verbatim and analysed thematically.

RESULTS

Two overriding themes emerged. The first was the sense that in normal practice therapists act as "benign dictators", committed to help their patients, but most comfortable when they, the professional, are in control. Following the adoption of the self-management approach therapists challenged themselves to empower stroke survivors to take control of their own recovery. However, therapists had to confront many internal and external challenges in this transition of power resulting in the promotion of a somewhat "reluctant democracy".

CONCLUSIONS

This study illustrates that stroke therapists desire a more participatory approach to rehabilitation. However, obstacles challenged the successful delivery of this goal. If self-management is an appropriate model to develop in post stroke pathways, then serious consideration must be given to how and if these obstacles can be overcome.

IMPLICATIONS FOR REHABILITATION

Stroke therapists perceive that self-management is appropriate for encouraging ownership of rehabilitation post stroke. Numerous obstacles were identified as challenging the implementation of self-management post stroke. These included: professional models, practices and expectations; institutional demands and perceived wishes of stroke survivors. For self-management to be effectively implemented by stroke therapists, these obstacles must be considered and overcome. This should be as part of an integrated therapy service, rather than as an add-on.

Self-management programmes for people post stroke: a systematic review

OBJECTIVE

To examine the evidence base underlying self-management programmes specific to stroke survivors.

DATA SOURCES

Eleven electronic databases were searched using combinations of keywords related to stroke and self-management.

REVIEW METHODS

Studies involving adults with a clinical diagnosis of stroke, which explored self-management interventions, were included. Study selection was verified by two reviewers who independently conducted methodological quality appraisal and data extraction using a tool developed by The American Academy for Cerebral Palsy and Developmental Medicine.

RESULTS

Fifteen studies were included in this review. Significant treatment effects in favour of the self-management intervention were found in six out of nine randomized controlled trials, and three out of six non-randomized trials in our review. Four randomized controlled trials involving more than 100 participants per trial reported statistically significant results in favour of the self-management group in relation to measures of disability, confidence in recovery, the stroke specific quality of life (sub-scales of family roles and fine motor tasks), and the physical component scale of the short form SF-36 Score. The wide range of outcome measures used prevented comparison across studies.

CONCLUSIONS

This review provides some preliminary support for the potential importance of self-management interventions after stroke. The most appropriate content and best approach for delivery of these interventions remains to be determined. Further high-quality randomized controlled trials are needed to test the feasibility, acceptability, and efficacy of stroke self-management programmes.

A short form of the General Self-Efficacy Scale (GSE-6): Development, psychometric properties and validity in an intercultural non-clinical sample and a sample of patients at risk for heart failure

OBJECTIVE

General self-efficacy has been found to be an influential variable related to the adaptation to stress and chronic illness, with the General Self-Efficacy (GSE) Scale by Jerusalem and Schwarzer being a reliable and valid instrument to assess this disposition. The aim of this study was to construct and test a short form of this scale to allow for a more economical assessment of the construct.

METHODS

The item characteristics of the original scale were assessed using an intercultural non-clinical sample (n=19,719). Six items with the highest coefficient of variation and good discrimination along the range of the trait were selected to build a short form of the instrument (GSE-6). Subsequently, the psychometric properties and the concurrent and predictive validity of the GSE-6 were tested in a longitudinal design with three measurements using a sample of patients with risk factors for heart failure (n=1,460).

RESULTS

Cronbach's alpha for the GSE-6 was between .79 and .88. We found negative associations with symptoms of depression (-.35 and -.45), anxiety (-.35), and vital exhaustion (-.38) and positive associations with social support (.30), and mental health (.36). In addition, the GSE-6 score was positively associated with active problem-focused coping (.26) and distraction/self-encouragement (.25) and negatively associated with depressive coping (-.34). The baseline GSE-6 score predicted mental health and physical health after 28 months, even after controlling for the respective baseline score. The relative stability over twelve and 28 months was r=.50 and r=.60, respectively, while the mean self-efficacy score did not change over time.

CONCLUSIONS

The six item short form of the GSE scale is a reliable and valid instrument that is useful for the economical assessment of general self-efficacy in large multivariate studies and for screening purposes.

Evaluation of an ICF-based patient education programme for stroke patients: a randomized, single-blinded, controlled, multicentre trial of the effects on self-efficacy, life satisfaction and functioning

OBJECTIVE

There is a current need for interventions that provide information to stroke survivors in a patient-centred, interactive, personalized and flexible manner. To this purpose, a standardized but content-flexible patient education programme based on the International Classification of Functioning, Disability and Health (ICF) was developed. This study evaluated the effect of this programme on perceived self-efficacy.

DESIGN

Single-blind, randomized, multi-centre controlled trial.

METHODS

Stroke patients undergoing neurological rehabilitation were enrolled. Perceived self-efficacy was measured with the Liverpool Self-Efficacy Scale. Secondary outcomes were life satisfaction and self-perception of the impact of the stroke on life, measured with the WHOQOL and the Stroke Impact Scale, respectively. Data obtained at baseline, post-intervention and 6-month follow-up were analysed using multi-level models of change.

RESULTS

Two hundred and thirteen patients received either the ICF-based patient education (n = 110) or an attention-placebo (n = 103) control intervention. Over time, patients' self-efficacy (p < .01) and participation (p < .01) improved, while emotional functioning (p < .01) deteriorated, although no significant between-group differences were observed. Explorative analyses showed that gender, loci of control, difficulty in accessing health services after discharge and life satisfaction were significant predictors of self-efficacy.

CONCLUSION

There was no significant benefit of the ICF-based patient education in comparison with an attention-placebo control group. Considering the importance of the programme for the further implementation of the ICF and the need of developing effective health education interventions for stroke, the methodology used was reviewed and an updated version proposed.

Self-management: a systematic review of outcome measures adopted in self-management interventions for stroke

Purpose

To systematically review the psychometric properties of outcome measures used in stroke self-management interventions (SMIs) to (1) inform researchers, clinicians and commissioners about the properties of the measures in use and (2) make recommendations for the future development of self-management measurement in stroke.

Methods

Electronic databases, government websites, generic internet search engines and hand searches of reference lists. Abstracts were selected against inclusion criteria and retrieved for appraisal and systematically scored, using the COSMIN checklist.

Results

Thirteen studies of stroke self-management originating from six countries were identified. Forty-three different measures (mean 5.08/study, SD 2.19) were adopted to evaluate self-SMIs. No studies measured self-management as a discreet concept. Six (46%) studies included untested measures. Eleven (85%) studies included at least one measure without reported reliability and validity in stroke populations.

Conclusions

The use of outcome measures which are related, indirect or proxy indicators of self-management and that have questionable reliability and validity, contributes to an inability to sensitively evaluate the effectiveness of stroke self-SMIs. Further enquiry into how the concept of self-management in stroke operates, would help to clarify the nature and range of specific self-management activities to be targeted and aid the selection of existing appropriate measures or the development of new measures.

Optimizing muscle power after stroke: a cross-sectional study

Background

Stroke remains a leading cause of disability worldwide and results in muscle performance deficits and limitations in activity performance. Rehabilitation aims to address muscle dysfunction in an effort to improve activity and participation. While muscle strength has an impact on activity performance, muscle power has recently been acknowledged as contributing significantly to activity performance in this population. Therefore, rehabilitation efforts should include training of muscle power. However, little is known about what training parameters, or load, optimize muscle power performance in people with stroke. The purpose of this study was to investigate lower limb muscle power performance at differing loads in people with and without stroke.

Methods

A cross-sectional study design investigated muscle power performance in 58 hemiplegic and age matched control participants. Lower limb muscle power was measured using a modified leg press machine at 30, 50 and 70% of one repetition maximum (1-RM) strength.

Results

There were significant differences in peak power between involved and uninvolved limbs of stroke participants and between uninvolved and control limbs. Peak power was greatest when pushing against a load of 30% of 1RM for involved, uninvolved and control limbs. Involved limb peak power irrespective of load (Mean:220 ± SD:134 W) was significantly lower (p < 0.05) than the uninvolved limb (Mean:466 ± SD:220 W). Both the involved and uninvolved limbs generated significantly lower peak power (p < 0.05) than the control limb (Mean:708 ± SD:289 W).

Conclusions

Significant power deficits were seen in both the involved and uninvolved limbs after stroke. Maximal muscle power was produced when pushing against lighter loads. Further intervention studies are needed to determine whether training of both limbs at lighter loads (and higher velocities) are preferable to improve both power and activity performance after stroke.

Assessment of additional endpoints for trials in acute stroke - what, when, where, in who?

Functional outcome in acute stroke trials among others is usually measured on the modified Rankin Scale. However, new onset of depression, cognitive decline, and communication deficits alone or in combination affect more than 25% of patients. This report summarizes the findings and conclusions of a workshop by the European Stroke Organization held in February 2011 We propose that assessment of mood disorders, cognitive impairment/dementia, language or communication dysfunction, and quality of life should supplement outcome measures after acute stroke.

Determining quality of life in stroke survivors

Post-stroke health-related quality of life (HRQoL) reflects a comprehensive view of subjective health and a measure of a person's perceived physical, mental and social health following stroke. Generic scales may enable comparisons between groups of patients with a diverse range of conditions, although they may underestimate the effect of stroke owing to its limited content validity. Stroke-specific HRQoL measures were designed to assess relevant domains that are important to stroke patients. The Stroke Impact Scale, the Stroke Specific Quality of Life scale and The Burden of Stroke Scale are specific HRQoL instruments developed in the last decade. Demographic factors, comorbidity, stroke severity, disability and psychosocial factors (e.g., post-stroke depression and social support) are significant predictors of HRQoL in stroke survivors. Stroke caregiver burden and HRQoL are inversely correlated. HRQoL measures are increasingly used to evaluate the effect of some therapeutic interventions in stroke survivors.

Balance and balance self-efficacy are associated with activity and participation after stroke: a cross-sectional study in people with chronic stroke

OBJECTIVES

To (1) examine the relationships between multiple poststroke mobility variables (gait speed, walking capacity, balance, balance self-efficacy, and falls self-efficacy) and activity and participation; and (2) determine which poststroke mobility variables are independently associated with activity and participation.

DESIGN

This is the primary analysis of a prospective cross-sectional study completed to understand the impact of mobility on activity and participation in people with chronic stroke.

SETTING

University-based research laboratory, hospitals, and stroke support groups.

PARTICIPANTS

People (N=77) with stroke greater than 6 months ago were included in the study if they were referred to occupational or physical therapy for physical deficits as a result of the stroke, completed all stroke related inpatient rehabilitation, had residual functional disability, scored a ≥4 out of 6 on the short, 6-item Mini-Mental State Examination, and were between the ages of 50 and 85.

INTERVENTIONS

Not applicable, this is a cross-sectional data collection of 1 timepoint.

MAIN OUTCOME MEASURES

We measured activity and participation with the validated International Classification of Functioning, Disability and Health Measure of Participation and Activities. Other variables included gait speed (10-meter walk), walking capacity (6-minute walk), balance (Berg Balance Scale), balance self-efficacy (Activities Specific Balance Confidence Scale), and falls self-efficacy (Modified Falls Efficacy Scale).

RESULTS

Only balance self-efficacy was found to be independently associated with poststroke activity (β=-.430, P<.022, 95% confidence interval [CI], -.247 to -.021) and participation (β=-.439, P<.032, 95% CI, -.210 to -.010).

CONCLUSIONS

Among people with chronic stroke, balance self-efficacy, not physical aspects of gait, was independently associated with activity and participation. While gait training continues to be important, this study indicates a need to further evaluate and address the psychological factors of balance and falls self-efficacy to obtain the best stroke recovery.

Self-Management of Upper Limb Recovery after Stroke: How Effectively Do Occupational Therapists and Physiotherapists Train Clients and Carers?

Aim:

A self-management approach to upper limb management following stroke has received little attention in the literature. The aim of the study was to investigate the impact of occupational therapists' and physiotherapists' standard practice on clients' and carers' self-management of upper limb recovery.

Method:

Fifteen clients, 7 carers, 11 occupational therapists and 7 physiotherapists were recruited. Therapists described five self-administered tasks they expected clients and carers were doing, using the Goal Attainment Scale (GAS). For each task, clients' and carers' performances were then evaluated using the GAS and their self-efficacy was rated on a 10-point Likert scale. A survey questionnaire investigated their perceptions of the training provided, with respect to a self-management approach.

Results:

At least a quarter of the self-administered tasks related to upper limb activity, strengthening and secondary prevention were performed below therapists' expectations. In contrast, mean self-efficacy ratings across these tasks were high (clients = 7.8–9.5, carers = 8.5–8.9). Seventy per cent of the self-management training strategies listed in the survey questionnaire were considered missing by more than 40% of carers.

Conclusion:

There is a need for therapy resources that enhance the content and delivery of self-management training related to upper limb management following stroke, particularly for carers.

A lifestyle intervention as supplement to a physical activity programme in rehabilitation after stroke: a randomized controlled trial

OBJECTIVE

To evaluate the effectiveness of lifestyle group intervention on well-being, occupation and social participation.

DESIGN

A randomized controlled trial.

SETTING

Senior centres in the community.

SUBJECTS

Of 204 stroke survivors screened, 99 (49%) were randomized three months after stroke whereby 86 (87%) participants (mean (SD) age 77.0 (7.1) years) completed all assessments (39 in the intervention group and 47 in the control group).

INTERVENTION

A lifestyle course in combination with physical activity (intervention group) compared with physical activity alone (control group). Both programmes were held once a week for nine months.

MAIN OUTCOME MEASURE

The Short Form Questionnaire (SF-36), addressing well-being and social participation. Assessments were performed at baseline and at nine months follow-up.

RESULTS

We found no statistically significant differences between the groups at the nine months follow-up in the SF-36. Adjusted mean differences in change scores in the eight subscales of SF-36 were; 'mental health' (+1.8, 95% confidence interval (CI) -4.0, +7.6), 'vitality' (-3.0, 95% CI -9.6, +3.6), 'bodily pain' (+3.3, 95% CI -7.8, +14.4), 'general health' (-1.6, 95% CI -8.4, +5.1), 'social functioning' (-2.5, 95% CI -12.8, +7.8), 'physical functioning' (+1.0, 95% CI -6.7, +8.6), 'role physical' (-7.1, 95% CI -22.7, +8.4), 'role emotional' (+11.8, 95% CI -4.4, +28.0).

CONCLUSIONS

Improvements were seen in both groups, but no statistically significant differences were found in the intervention group compared to controls. An intervention comprising regular group-based activity with peers may be sufficient in the long-term rehabilitation after stroke.

Negative illness perceptions are associated with impaired quality of life in patients after long-term remission of Cushing's syndrome

OBJECTIVE

Illness perceptions pertain to the pattern of beliefs patients develop about their illness. Illness perceptions are determinants of quality of life (QoL). Factors contributing to persisting impaired QoL after Cushing's syndrome (CS) remain largely unknown. Therefore, the objective of this study was to explore illness perceptions, as potentially modifiable psychological factors, in relation to QoL in patients with long-term remission of CS.

DESIGN

Cross-sectional study.

METHODS

We included patients with long-term remission of CS (n=52). Illness perceptions were evaluated using the Illness Perception Questionnaire (IPQ)-Revised, and QoL was measured using the physical symptom checklist, EuroQoL-5D (EQ-5D), and the CushingQoL. Reference data were derived from recent studies and included patients with vestibular schwannoma (n=80), acute (n=35) or chronic (n=63) pain, and chronic obstructive pulmonary disease (COPD; n=171).

RESULTS

Illness perceptions showed a strong correlation with QoL. Patients with CS scored distinctively more negative on the IPQ compared with patients with vestibular schwannoma and patients with acute pain, and also reported more illness-related complaints (all P<0.01). There were also some differences in illness perceptions between patients with CS and patients with chronic pain and patients with COPD, but there was no distinct pattern.

CONCLUSIONS

Patients after long-term remission of CS report more negative illness perceptions compared with patients with other acute or chronic conditions. Further research is needed to assess whether QoL in CS can be improved by addressing these illness perceptions, for example, by a self-management intervention program.
