Qualitative Research on Fatigue Associated with Depression: Content Validity of the Fatigue Associated with Depression Questionnaire (FAsD-V2)

Systematic Review of the Effect of a One-Day Versus Seven-Day Recall Duration on Patient Reported Outcome Measures (PROMs)

BACKGROUND

There is ongoing uncertainty around the most suitable recall period for patient-reported outcome measures (PROMs).

METHOD

This systematic review integrates quantitative and qualitative literature across health, economics, and psychology to explore the effect of a one-day (or '24-h') versus seven-day (or 'one week') recall period. The following databases were searched from database inception to 30 November 2021: MEDLINE, EMBASE, PsycINFO, Web of Science, EconLit, CINAHL Complete, Cochrane Library, and Sociological Abstracts. Studies were included that compared a one-day (or '24-h') versus seven-day (or weekly) recall period condition on patient-reported scores for PROM and Health-Related Quality-of-Life (HRQoL) instrument scores in adult populations (aged 18 and above) or combined paediatric and adult populations with a majority of respondents aged over 18 years. Studies were excluded if they assessed health behaviours only, used ecological momentary assessment to derive an index of daily recall, or incorporated clinician reports of patient symptoms. We extracted results relevant to six domains with generic health relevance: physical functioning, pain, cognition, psychosocial wellbeing, sleep-related symptoms and aggregated disease-specific signs and symptoms. Quantitative studies compared weekly recall scores with the mean or maximum score over the last seven days or with the same-day recall score.

RESULTS

Overall, across the 24 quantitative studies identified, 158 unique results were identified. Symptoms tended to be reported as more severe and HRQoL lower when assessed with a weekly recall than a one-day recall. A narrative synthesis of 33 qualitative studies integrated patient perspectives on the suitability of a one-day versus seven-day recall period for assessing health state or quality of life. Participants had mixed preferences, some noted the accuracy of recall for the one-day period but others preferred the seven-day recall for conditions characterised by high symptom variability, or where PROMs concepts required integration of infrequent experiences or functioning over time.

CONCLUSION

This review identified a clear trend toward higher symptom scores and worse quality of life being reported for a seven-day compared to a one-day recall. The review also identified anomalies in this pattern for some wellbeing items and a need for further research on positively framed items. A better understanding of the impact of using different recall periods within PROMs and HRQoL instruments will help contextualise future comparisons between instruments. Questionnaires ask patients about their health over different time periods (e.g., "what were your symptoms like over the last week?" versus "what were your symptoms like today?"). Studies find that people may report their symptoms as more severe when they are asked to think about their symptoms over the last week compared to the last day. Understanding how different time periods influence patient responses will allow researchers to compare and develop new questionnaires and may help clinicians to choose the best questionnaire to understand their patient's condition. We conducted a systematic literature review on studies which had looked at the impact of using different recall periods on patient responses. We found 24 studies that compared patient scores from questionnaires asking their health "over the last day" compared to "over the last week". Overall, symptoms tended to be reported as more severe and health as poorer when they were reported over the last week compared to the last day on average. We also found 33 studies that asked patients to describe which recall period they preferred. Patients had mixed preferences with more preferring a seven-day recall where symptoms and health impacts varied a lot.

Patient Expectations and Experiences of Antidepressant Therapy for Major Depressive Disorder: A Qualitative Study

PURPOSE

This qualitative study explored patient perceptions of the most burdensome symptoms of major depressive disorder (MDD), the impact of symptoms on patients' daily lives, and patient expectations and experiences regarding the timing of onset of antidepressant pharmacotherapy.

PATIENTS AND METHODS

Data were collected through facilitated, patient focus-group sessions in the USA between May and June 2019. Participants were adults with confirmed MDD who reported a major depressive episode within the past 2 years, for which they had received pharmacologic treatment for ≥6 weeks. The semi-structured discussion focused on the key topics of bothersome symptoms of MDD, the impact of symptoms on quality of life, and the effects of antidepressant treatment. Interviews were audio-recorded; findings were summarized using a content-analysis approach.

RESULTS

Five focus-group sessions were undertaken, involving a total of 29 patients (each attended one session; mean age, 43.4 years; 72.4% female). Mean time since confirmed diagnosis of MDD was 13.1 years. The most commonly prescribed antidepressants received were bupropion (41.4% of participants), escitalopram (34.5%), and sertraline (34.5%). The most frequently reported bothersome MDD symptoms were fatigue (mentioned by 58.6% of participants), lack of motivation/loss of interest (51.7%), anxiety/panic (44.8%), sadness (41.4%), and lack of concentration/brain fog (41.4%). Socialization, family life, and work were the areas in which quality of life was most impacted. Participants expressed dissatisfaction with their antidepressant treatment. Fast symptom resolution was mentioned as a priority (defined as <1 week by 38.5% of participants and ≤1 month by 65.4%). Most participants had not experienced fast relief from their symptoms with current or previous antidepressant medications.

CONCLUSION

Results of this qualitative study suggest that fatigue, anhedonia, cognitive symptoms, and anxiety are some of the most bothersome symptoms for patients with MDD and highlight the importance of obtaining rapid relief from these symptoms in order to improve outcomes and patient satisfaction with antidepressant medication.

Moxibustion at 'Danzhong' (RN17) and 'Guanyuan' (RN4) for fatigue symptom in patients with depression: Study protocol clinical trial (SPIRIT Compliant)

BACKGROUND

Fatigue is one of the most prevalent and debilitating symptoms of major depressive disorder (MDD). The effective management of depression-related fatigue has an important impact on the patient's abilities, functioning, and quality of life (QOL). Moxibustion has been widely used in Traditional Chinese Medicine to manage fatigue. Recent studies have also demonstrated that moxibustion is effective for treating cancer-related fatigue and chronic fatigue syndrome. However, there is not sufficient data supporting the effect of moxibustion for depression-related fatigue. Therefore, this randomized, assessor-blinded, wait-list controlled trial is designed to evaluate the effectiveness, safety, and feasibility of moxibustion treatment for depression-related fatigue.

METHODS

One hundred and seventy-six participants who meet the diagnostic criteria for depression in the International Classification of Diseases, tenth revision (ICD-10), and who also have a score of ≥1 on the 13 item of the Hamilton Depression Rating Scale-17 (HAMD-17), will be enrolled. At study entry, participants will undergo anti-depressant treatment for at least 1 month. Then those who still have a score of ≥1 on the 13 item of the HAMD-17 will be randomly allocated to either a moxibustion group or wait-list control group in a ratio of 1:1. Anti-depressants will be provided for both groups during the whole process of the study period. Participants in the moxibustion group will undergo 14 sessions of moxibustion (over 2 weeks) with anti-depressant treatment, and participants in the wait-list control group will receive only anti-depressant treatment. Subsequently, participants in the moxibustion group will be followed-up for 4 weeks. The primary outcome measure will be the Fatigue Severity Scale (FSS). The secondary outcome measure will be the HAMD-17. Safety will be assessed by monitoring adverse events during the study. Trial feasibility will also be assessed in this study.

DISCUSSION

The results of this study may provide evidence for the efficacy of moxibustion as an adjunct to antidepressants for depression-related fatigue, and promote a more widespread foundation for the selection of moxibustion in the clinical setting as well as for future research in moxibustion therapy.

TRIAL REGISTRATION

This study protocol was registered at the Chinese Clinical Trial Registry (ChiCTR1800016905).

Animal models of fatigue in major depressive disorder

Fatigue is common in a host of neurological and psychiatric disorders including depression and often continues unabated even after primary symptoms of disease are treated. Its high estimated prevalence combined with the lack of effective medicines has engaged the preclinical research community to search for fatigue models. The present review briefly summarizes the most common animal models that have been brought forward along with some of the associated pharmacological validation data. Like all preclinical models, these models have issues that need to be appreciated in the generation and interpretation of data for the purposes of translation to human disease; specifically, there are deficiencies in construct validity, a lack of medicines that effectively address residual fatigue symptoms, and difficulties in defining specificity with respect to drug effects on fatigue per se. Nonetheless, existing animal models of fatigue arguably serve the valuable purpose of encouraging research in this large area of unmet medical need. Data from these models are predicted to engender human experimentation and the further development of improved model systems.

Fatigue and Depression in Iranian Amyotrophic Lateral Sclerosis Patients in Tehran in 2012

Introduction

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with a progressive and rapid course. Fatigue and depression are common among ALS patients. The aim of this study was to determine the relationship between depression and fatigue in Iranian ALS patients.

Methods

In this 2012 cross-sectional study, 40 ALS patients, including 22 females and 18 males, were selected through consecutive relapsing-remitting, and 40 age- and gender-matched health controls (HCs) were recruited from Loghman Hakim Hospital in Tehran, Iran. The Persian version of the Fatigue Severity Scale (FSS-Per) questionnaire and depression substance of Hospital Anxiety and Depression Scale (HADS) were used to assess fatigue and depression. Data were analyzed using the Kolmogorov-Sminov Test, Levene’s test, Independent Samples t-test, and Pearson product-moment correlation coefficient.

Results

We identified a significant and positive relationship between fatigue and depression in patients with ALS (p=0.000). Furthermore, the scores of fatigue and depression in ALS patients were higher than in non-ALS patients.

Conclusion

The results indicated that there was a relationship between fatigue and depression in ALS patients and that early intervention services can improve these symptoms. Further studies are suggested to investigate the direction of such relationship.
