Effect of Self-Efficacy on Quality of Life in People With Mild Cognitive Impairment and Mild Dementia: The Mediating Roles of Depression and Anxiety

Objectives: To examine the mediating effects of depression and anxiety in the relationship between self-efficacy and quality of life among people with mild cognitive impairment (MCI) or mild dementia. Method: A total of 196 patients diagnosed with MCI or dementia due to Alzheimer disease completed structured measures of self-efficacy, quality of life, and depressive and anxiety symptoms. We examined direct and mediated effects by fitting structural equation models to data. Results: Our analyses supported that the effects of self-efficacy on quality of life may be partially mediated by depression and anxiety. Both anxiety and depression had significant mediating effects, with depression showing a stronger effect. Conclusion: These results suggest that increased self-efficacy may have a positive effect on quality of life in people with MCI or dementia—partly by reducing depression and anxiety. These findings may have important practical implications for tailoring therapeutic interventions.

ABSTRACTBackground:Many people with mild cognitive impairment (MCI) or early dementia suffer from concomitant depression and anxiety disorders, which in some cases, may be related difficulties adjusting to their diagnosis and associated cognitive problems. Successful adjustment and alleviation of depression and anxiety symptoms in these people is of critical importance for quality of life and may also help prevent, or delay, further cognitive decline. A variety of psychosocial intervention approaches has been trialed with this group.Method:The literature was systematically searched for community-based intervention studies that aim to improve depression, anxiety, or adjustment. Studies were included or excluded using a priori criteria. Once included, the quality of studies was evaluated using pre-set criteria.Results:Seventeen of 925 studies identified through literature databases and manual searches met the inclusion criteria. Of these, 16 were considered to be of at least “adequate quality.” These included seven randomized controlled trials and eight pre–post studies. A diverse range of psychotherapeutic approaches, formats (individual or group), outcome measures, inclusion criteria, and cultural contexts were apparent, making comparisons between studies challenging.Conclusions:Several studies have demonstrated positive findings in the treatment of depression in older adults with early dementia using problem solving and modified cognitive behavior therapy (CBT) approaches. Amongst the large range of approaches trialed to improve adjustment and quality of life for patients with MCI and early dementia, some approaches, such as modified CBT, have shown promise. There is a need for replication studies using more rigorous methodology before clear clinical recommendations can be made.

The Relationship

Background and Objectives Multiple sclerosis (MS) has a broad spectrum of physical, social, psychological effects and significant impact on quality of life (QoL). Several studies has showed the importance of self-efficacy as a predictor of QoL in patients with MS.This study aims at evaluating the robustness of the relationship between self-efficacy and QoL. Specifically it aims to test whether such relation will vanish under the following conditions: using a general measure of self-efficacy and controlling for level of impairment defined as a broad construct dealing with physical, social and working changes due to the illness condition. Methods One hundred-fifty five participants responded to a questionnaire, including QoL and general self-efficacy measures, socio demographic and clinical variables. Two nested structural equation models that differ for the presence or absence of the path connecting self-efficacy and QoL was estimated.Results and Conclusions The hypothesis of the vanishing of the relationship between self-efficacy and QoL had to be rejected. These results support the genuineness of this relation and emphasize the importance of interventions promoting self-efficacy to improve QoL in chronic diseases such as MS. From a methodological perspective this study is an example of the usefulness of formative indicators in QoL studies.
