This systematic review assessed the psychometric properties and the cross-cultural adaptation of the University of California and Los Angeles Loneliness scale (UCLA-LS) in adults. A systematic search of four electronic databases (PubMed, EMBASE, Scopus, and PsycINFO) was conducted from inception until March 2021. We followed the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines for data extraction and evidence synthesis. Eighty-one studies assessed the validity and reliability of the UCLA-LS, translated into many languages, and applied across several countries/societies. Three versions of the 20-item and nine short versions of the UCLA-LS with 3 to 20 questions were identified. High-quality evidence supported the internal structure of the UCLAs: 4, 6, 7 and 10, while low-to moderate-quality evidence supported the construct validity of the UCLAs: 3, 4, 6, 8, 16 and 20. Moderate-quality evidence supported the test-retest reliability of version 3 UCLA-20 with excellent interclass coefficients values of 0.76-0.93. The UCLAs: 4, 6, 7 and 10 had the most robust internal structure and may therefore be the most useful for informing clinicians and social psychologists engaged in assisting those with loneliness., Author(s): Sanaa A.

The Hospital Anxiety and Depression Scale (HADS) is used to assess anxiety and depression in individuals with chronic obstructive pulmonary disease (COPD); however, its measurement properties lack critical appraisal. We aimed to summarize and critically appraise the validity, reliability, and responsiveness of the HADS in COPD. Five electronic databases were searched. The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines were used to assess the methodological and evidence quality in the selected studies. Twelve studies assessed the psychometric properties of the HADS-Total and its subscales HADS-Anxiety and HADS-Depression in COPD. High-quality evidence supported the structural and criterion validity of the HADS-A, the internal consistency of the HADS-T, HADS-A, and HADS-D with Cronbach's alpha values of 0.73–0.87, and before–after treatment responsiveness of HADS-T and its subscales (minimal clinically important difference = 1.4–2; effect size = 0.45–1.40). Moderate-quality evidence supported the test–retest reliability of the HADS-A and HADS-D with excellent coefficient values of 0.86–0.90. The HADS-A is recommended for use in individuals with stable COPD. The lack of high-quality evidence on the validity of the HADS-D and HADS-T prevented drawing robust conclusions about their clinical utility in COPD. Anxiety and depression are common in individuals with chronic obstructive pulmonary disease (COPD). Anxiety and depression can negatively impact the physical and mental health of individuals with COPD. The HADS can be used to assess anxiety and depression in COPD in rehabilitation settings.

Introduction: Inspiratory muscle training (IMT) is one possible strategy to ameliorate respiratory muscle weakness due to invasive mechanical ventilation. Recent systematic reviews have focused on respiratory outcomes with minimal attention to physical function. The newest systematic review searched the literature until September 2017 and a recent preliminary search identified 5 new randomized controlled trials focusing on IMT in critical care. As such, a new systematic review is warranted to summarize the current body of evidence and to investigate the effect of IMT on physical function in critical care. Materials and methods: We will search for three main concepts ("critical illness", "inspiratory muscle training", "RCT") across six databases from their inception (MEDLINE, EMBASE, Emcare, AMED, CINAHL, CENTRAL) and ClinicalTrials.gov. Two reviewers will independently screen titles, abstracts, and full texts for eligibility using the Covidence web-based software. Eligible studies must include: (1) adult (≥18 years) patients admitted to the intensive care unit (ICU) who required invasive mechanical ventilation for ≥24 hours, (2) an IMT intervention using a threshold device with the goal of improving inspiratory muscle strength, with or without usual care, and (3) randomized controlled trial design. The primary outcome of interest will be physical function. We will use the Cochrane Risk of Bias Tools (ROB2) and will assess the quality of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tool. This protocol has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA- P) guidelines and is registered with the International Prospective Register of Systematic Reviews (PROSPERO). Conclusion: Results will summarize the body of evidence of the effect of IMT on physical function in critically ill patients. We will submit our findings to a peer-reviewed journal and share our results at conferences. [ABSTRACT FROM AUTHOR]

BACKGROUND: People with interstitial lung disease (ILD) want to actively manage their condition; however, the effects of self-management interventions (SMIs) in this population have not been synthesized. This review summarizes the effects of SMIs on health-related quality of life (HRQOL), functional status, psychological and social factors, symptoms, exacerbations, health care utilization, and survival in people with ILD. METHODS: The protocol of this systematic review was registered (PROSPERO ID: CRD42022329199). Six digital databases were searched in May 2022 with monthly updates until August 2023. Studies implementing SMIs in people with any type of ILD were included. Risk of bias (RoB) and quality of evidence were assessed with the Cochrane tool for RoB assessment and the grading of recommendations, assessment, development, and evaluations. Meta-analysis was used to summarize the results. RESULTS: Four studies that examined 217 participants (81% male, 71 y old, 91% idiopathic pulmonary fibrosis) were included. SMIs were highly heterogeneous. Meta-analysis showed no difference in HRQOL (standardized mean difference: 0.08 [95% CI 20.21 to 0.37], P .58) nor in the secondary outcomes. No evidence for the effects of SMIs on functional capacity, exacerbations, and survival was found. The quality of evidence ranged from low to very low. CONCLUSIONS: There is low to very low-quality evidence that SMIs have no effect in people with ILD. However, this conclusion is limited by high methodological heterogeneity. A consensus definition of SMIs is needed to implement more comparable interventions and strengthen results. [ABSTRACT FROM AUTHOR]

Informal caregivers play an important role in chronic disease management but their experience is often neglected. The objective of this study was to explore the content validity of the Zarit Burden Interview (ZBI) in caregivers of individuals with COPD in Canada and Portugal. Cognitive debriefing interviews were conducted with informal caregivers of individuals with moderate to very severe COPD. Participants completed the ZBI and verbalised their thinking process to assess the adequacy of the questionnaire's content and instructions. Content validity was assessed using deductive content analysis of interviews and descriptive statistics of questionnaire responses. Nine caregivers from Canada (age = 67 ± 8 years) and 13 from Portugal (age = 69 ± 7 years) participated. For Canadian caregivers, 3/22 items were not understood, and 8/22 items were not relevant to at least 1/3 of them. For Portuguese caregivers, 1/22 items were not understood, and 20/22 items were not relevant to at least 1/3 of them. The distribution of response choices was approximately symmetrical for 17/22 items in the Canadian sample. The response option "no/never" was selected by at least 75% of Portuguese participants for 18/22 items. The instrument was well understood by caregivers of people with COPD, but its relevance is uncertain. Informal caregivers provide essential care for people living with disability and chronic disease, but their experience is often neglected. The Zarit Burden Interview assesses caregiver burden but has not been validated in caregivers of people with chronic obstructive pulmonary disease. In its current form, the Zarit Burden Interview does not adequately represent the experience of COPD caregivers. We recommend selecting tools that assess caregiver burden that have been validated in the caregiver population of interest. [ABSTRACT FROM AUTHOR]
