Production of nouns and adjectives of children with cochlear implants and of children with typical hearing.

This analytical cross-sectional study aimed to investigate the production of nouns and adjectives in 62 children between the ages 5 and 7, with 31 children having Cochlear Implants (CIs) and 31 children having Typical Hearing (TH). The study compaired their performance in a picture naming test of nouns and adjectives. Poisson regression models were fitted to compare the responses of both groups of children, and intra-subject differences between responses to the noun and adjective naming tasks were also analyzed. The results showed that both groups of children produced the same number of non-responses of nouns and of adjectives and a higher number of correct productions of nouns than of adjectives. However, children with CIs produced more errors when naming adjectives than when naming nouns, while this difference is not observed in children with TH. The comparative analysis between both groups of children indicates that children with CIs produced a higher proportion of non-responses when naming nouns, but the same proportion as children with TH when naming adjectives. Children with CIs also produced fewer correct nouns and adjectives and more errors than children with TH. Vocabulary expansion and repair of production errors in children with CIs should be targeted by speech-language pathologists in intervention programs.

Effect of synchronous remote-based interventions on suicidal behaviours: protocol for a systematic review and meta-analysis.

INTRODUCTION: Suicide is among the leading causes of preventable death worldwide. The impact of suicide affects the personal, social and economic levels. Therefore, its prevention is a priority for public health systems. Previous studies seem to support the efficacy of providing active contact to people who have made a suicide attempt. The current systematic review and meta-analysis aims to investigate the efficacy of distance suicide prevention strategies implemented through synchronous technology-based interventions. METHODS AND ANALYSIS: This protocol is designed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. The bibliographical searches were conducted in the databases PubMed, PsycINFO, Scopus and Web of Science in April 2022, with no restrictions on the time of publication and limited to publications in English or Spanish. The search strategy was performed using free-text terms and Medical Subject Headings terms: suicide, follow-up, synchronous, remote, telehealth, telephone, hotline, video-conference and text message. Two reviewers will independently conduct study screening, selection process, data extraction and risk of bias assessment. The analysis and synthesis of the results will be both qualitative and quantitative. A narrative synthesis, presented in a comprehensive table, will be performed and meta-analysis will be conducted, as appropriate, if sufficient data are provided. ETHICS AND DISSEMINATION: The present review and meta-analysis will not require ethical approval, as it will use data collected from previously published primary studies. The findings of this review will be published in peer-reviewed journals and widely disseminated. PROSPERO REGISTRATION NUMBER: CRD42021275044.

Linguistic Intervention Strategies Speech-Language Pathologists Use With Children Using Cochlear Implants.

The aim of this study was to explore the strategies that speech-language pathologists (SLPs) use during their linguistic interventions on children with cochlear implants (CIs). The sample comprised 7 SLPs in interactions with 62 children, 31 with CIs and 31 with typical hearing (TH), from 5 to 7 years of age. Two linguistic activities were used: conversation and naming. With children with CIs, the SLPs used 3.8 times more adaptation strategies and 5 times more educational strategies in the conversation activity, and 1.4 times more educational strategies in the naming activity than with children with TH. Communication strategies were significantly more frequent in the conversation activity than in the naming activity while educational strategies were more frequent in the naming activity than in the conversation activity. The auditory age of children with CIs also influenced the use of these two types of strategies, increasing the use of communication strategies by 0.6% and decreasing the use of educational strategies by 1.2% for each month of increase in the auditory age. In order to foster linguistic development, the SLPs used a wide variety of strategies with the children with CIs, adjusting them to the activity and the auditory age.

Methods for Heart Rate Variability Biofeedback (HRVB): A Systematic Review and Guidelines.

Heart Rate Variability Biofeedback (HRVB) has been widely used to improve cardiovascular health and well-being. HRVB is based on breathing at an individual's resonance frequency, which stimulates respiratory sinus arrhythmia (RSA) and the baroreflex. There is, however, no methodological consensus on how to apply HRVB, while details about the protocol used are often not well reported. Thus, the objectives of this systematic review are to describe the different HRVB protocols and detect methodological concerns. PsycINFO, CINALH, Medline and Web of Science were searched between 2000 and April 2021. Data extraction and quality assessment were based on PRISMA guidelines. A total of 143 studies were finally included from any scientific field and any type of sample. Three protocols for HRVB were found: (i) "Optimal RF" (n = 37), each participant breathes at their previously detected RF; (ii) "Individual RF" (n = 48), each participant follows a biofeedback device that shows the optimal breathing rate based on cardiovascular data in real time, and (iii) "Preset-pace RF" (n = 51), all participants breathe at the same rate rate, usually 6 breaths/minute. In addition, we found several methodological differences for applying HRVB in terms of number of weeks, duration of breathing or combination of laboratory and home sessions. Remarkably, almost 2/3 of the studies did not report enough information to replicate the HRVB protocol in terms of breathing duration, inhalation/exhalation ratio, breathing control or body position. Methodological guidelines and a checklist are proposed to enhance the methodological quality of future HRVB studies and increase the information reported.

Central Sensitization and Chronic Pain Personality Profile: Is There New Evidence? A Case-Control Study.

BACKGROUND: Personality traits are relevant for pain perception in persistent pain disorders, although they have not been studied in depth in sensitized and nonsensitized patients with knee osteoarthritis (OA). OBJECTIVE: To explain and compare the personality profile of patients with OA, with and without central sensitization (CS), and fibromyalgia (FM). SETTING: Participants were selected at the Rheumatology Department in two major hospitals in Spain. PARTICIPANTS: Case-control study where the sample consists of 15 patients with OA and CS (OA-CS), 31 OA without CS (OA-noCS), 47 FM, and 22 controls. We used a rigorous and systematic process that ensured the sample strictly fulfilled all the inclusion/exclusion criteria, so the sample is very well delimited. PRIMARY OUTCOME MEASURES: Personality was assessed by the Temperament and Character Inventory of Cloninger. RESULTS: The percentile in harm-avoidance dimension for the FM group is higher compared to OA groups and controls. The most frequent temperamental profiles in patients are cautious, methodical, and explosive. Patients with FM are more likely to report larger scores in harm-avoidance, with an increase in logistic regression adjusted odds ratio (ORadj) between 4.2% and 70.2%. CONCLUSIONS: Harm-avoidance seems to be the most important dimension in personality patients with chronic pain, as previously found. We found no differences between OA groups and between sensitized groups, but there are differences between FM and OA-noCS, so harm-avoidance might be the key to describe personality in patients with CS rather than the presence of prolonged pain, as found in the literature before.

Co-viewing an Educational Video: A Pilot Study About Mother-DHH Child Interaction.

This study analyzes the mother-child interaction that takes place after co-viewing an educational video, comparing a group of 12 Spanish hearing mothers of deaf or hard of hearing (DHH) 7- to 9-year-olds and a group of 12 Spanish mothers of an age-matched cohort of children with typical hearing (TH). The results show that, in order to ascertain what the children have understood from the video, the mothers of the DHH children ask significantly more questions than the mothers of children with TH. Regarding the strategies that they use to prompt their children to explain the video, the mothers of the DHH children make reference most of all to shared experiences and focus their attention on contents of the video, whereas the mothers of children with TH tend to encourage their children to begin or continue the explanation of the video. The age of the hearing mothers was not found to have any effect on these results.

Pragmatic Competence of Children With Cochlear Implants in Linguistic Activities.

The objective of the study was to analyze the pragmatic competence of children with cochlear implants (CIs). The researchers explored whether children with CIs participated in communicative exchanges in a similar way to children with typical hearing (TH), as well as how the participation of children with CIs was regulated by the activity they performed. The sample consisted of 31 children with CIs (prelingually deaf, with a hearing age equal to or greater than 2 years) and 31 children with TH. The researchers used two activities to carry out the study: conversation and picture naming. The results showed that the children with CIs participated in longer communicative exchanges than their peers with TH and had greater difficulty providing adequate responses to their interlocutor. The type of linguistic activity and their hearing age influenced the responses of the children with CIs.

Could hand-eye laterality profiles affect sport performance? A systematic review.

Background: Laterality effects on sports performance have been a field of interest for the sports sciences, especially in asymmetrical sports, which require the preferential use of one side of the body. Some sports in particular involve the visual system and ocular laterality, due to the need to clearly focus on a dynamic object (ball, opponent, projectile, etc.). The relationship between manual and ocular laterality results in two perceptual-motor profiles, one where the dominant hand and eye are ipsilateral (uncrossed hand-eye laterality profile, UC-HELP), and the other where they are contralateral (crossed hand-eye laterality profile, C-HELP). Methodology: A systematic review of the literature was carried out to determine the prevalence of hand-eye laterality profiles in the different sports modalities and their relationship with psychological factors and sports performance. Searches of PsycInfo, Medline, Scopus and grey literature identified 14 studies (2,759 participants) regarding hand-eye laterality in sports that met the eligibility criteria. Results: Previous studies have estimated that between 10-30% of the general population exhibit a C-HELP, and 70-90% have an UC-HELP. The results of the reviewed studies indicate that in some sports the percentage of C-HELP is higher in regular and high-level athletes than in the normal population: golf (52.55%), soccer (53%), tennis (42%) and team sports (50.7%). In target sports (archery and shooting) athletes with an UC-HELP seem to have an advantage given the significant concentration of this profile in the highest performing populations (82.3%). In basketball, cricket and golf, the literature reviewed also reported biomechanical differences in the execution of some techniques between the two profiles. We did not find any study in our review that related hand-eye laterality with cognitive, tactical, or psychological aspects of athletes. Conclusions: These results should be taken with great caution due to the potential bias linked to the methodologies used in the investigations, the heterogeneity in the assessment of hand-eye laterality, the few studies available on the subject and the indirect nature of many of the observed relationships between performance and laterality. For further investigation, we propose a standardized terminology and protocol of hand-eye laterality assessment in sports. The advancement in knowledge about hand-eye laterality profiles, along with the study of the relationship with psychological or tactical-sports patterns, can contribute to more effective development plans for athletes and can be a complement to talent detection.

Prevalence of sending, receiving and forwarding sexts among youths: A three-level meta-analysis.

By systematic review with a three-level, mixed-effects meta-analysis, this paper examines the prevalence of sexting experiences among youths aimed at analyzing conceptual and methodological moderators that might explain its heterogeneity. A search was conducted of five bibliographic databases and grey literature up until February 2020. The risk of bias in primary studies was assessed. A total of seventy-nine articles met the set inclusion criteria. Mean prevalences for sending, receiving and forwarding sexts were .14 (95% CI: .12, .17), .31 (95% CI: .26, .36) and .07 (95% CI: .05, .09), respectively, expressed as fractions over one. Moderator analyses showed that all sexting experiences increased with age (e.g., the mean prevalence for sending sexts at the age of 12 was .04, whereas, at the age of 16, it was .21) and year of data collection (e.g., the mean prevalence for sending sexts in studies collecting data in 2009 was .07, whereas, in studies collecting data in 2018, it was .33). Subgroup analysis revealed that studies with probabilistic samples led to significantly lower mean prevalences for the sexting experiences of sending (.08, 95% CI: .06, .11), receiving (.19, 95% CI: .15, .24) and forwarding sexts (.04, 95% CI: .03, .07). Self-reported administration procedures also led to more homogeneous prevalence estimates than interviews. Prevalence estimates also varied according to the type of media content (e.g., the mean prevalence for sending sexual text messages was .22, whereas, for sending sexual images or videos, it was .12). Overall, our meta-analysis results suggest high and increasing prevalences of sending and receiving sexts among youths.

Development and Validation of the Adolescent Sexting Scale (A-SextS) with a Spanish Sample.

"Sexting" is generally defined as the exchange of sexual media content via the internet. However, research on this topic has underscored the need to seek greater consensus when considering different conceptual elements that make up this definition. The aim of this study was to develop and validate an instrument for measuring sexting among adolescents, in order to cover a gap identified in the previous literature. The Adolescent Sexting Scale (A-SextS for short) was developed for validation on a sample of 579 Spanish secondary school pupils between the ages of 11 and 18. Evidence for face, content, concurrent, and criterion validity were assessed. A comprehensive set of 64 items, covering six defining characteristics of sexting (e.g., actions, recipient, media format, degree of sexual explicitness), was constructed after conducting an extensive literature review, two discussion groups, and a pilot study. Sexting prevalence rates measured by A-SextS were mostly concurrent with those found in previous studies. A-SextS subscales produced statistically significant positive associations with pornography consumption and physical sexual intercourse. The study shows that A-SextS can be an integrating instrument that facilitates a rigorous and comprehensive assessment of adolescent sexting experiences, as well as the formulation of an operationalized definition of the practice of sexting.

Tools to assess the measurement properties of quality of life instruments: a meta-review.

OBJECTIVE: This meta-review aims to discuss the methodological, research and practical applications of tools that assess the measurement properties of instruments evaluating health-related quality of life (HRQoL) that have been reported in systematic reviews. DESIGN: Meta-review. METHODS: Electronic search from January 2008 to May 2020 was carried out on PubMed, CINAHL, PsycINFO, SCOPUS, WoS, Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) database, Google Scholar and ProQuest Dissertations and Theses. RESULTS: A total of 246 systematic reviews were assessed. Concerning the quality of the review process, some methodological shortcomings were found, such as poor compliance with reporting or methodological guidelines. Regarding the procedures to assess the quality of measurement properties, 164 (66.6%) of reviewers applied one tool at least. Tool format and structure differed across standards or scientific traditions (ie, psychology, medicine and economics), but most assess both measurement properties and the usability of instruments. As far as the results and conclusions of systematic reviews are concerned, only 68 (27.5%) linked the intended use of the instrument to specific measurement properties (eg, evaluative use to responsiveness). CONCLUSIONS: The reporting and methodological quality of reviews have increased over time, but there is still room for improvement regarding adherence to guidelines. The COSMIN would be the most widespread and comprehensive tool to assess both the risk of bias of primary studies, and the measurement properties of HRQoL instruments for evaluative purposes. Our analysis of other assessment tools and measurement standards can serve as a starting point for future lines of work on the COSMIN tool, such as considering a more comprehensive evaluation of feasibility, including burden and fairness; expanding its scope for measurement instruments with a different use than evaluative; and improving its assessment of the risk of bias of primary studies.

mHealth technology for ecological momentary assessment in physical activity research: a systematic review.

OBJECTIVE: To systematically review the publications on ecological momentary assessment (EMA) relating to physical activity (PA) behavior in order to classify the methodologies, and to identify the main mHealth technology-based tools and procedures that have been applied during the first 10 years since the emergence of smartphones. As a result of this review, we want to ask if there is enough evidence to propose the use of the term "mEMA" (mobile-based EMA). DESIGN: A systematic review according to PRISMA Statement (PROSPERO registration: CRD42018088136). METHOD: Four databases (PsycINFO, CINALH, Medline and Web of Science Core Collection) were searched electronically from 2008 to February 2018. RESULTS: A total of 76 studies from 297 potential articles on the use of EMA and PA were included in this review. It was found that 71% of studies specifically used "EMA" for assessing PA behaviors but the rest used other terminology that also adjusted to the inclusion criteria. Just over half (51.3%) of studies (39) used mHealth technology, mainly smartphones, for collecting EMA data. The majority (79.5%) of these studies (31 out of 39) were published during the last 4 years. On the other hand, 58.8% of studies that only used paper-and-pencil were published during the first 3 years of the 10-year period analyzed. An accelerometer was the main built-in sensor used for collecting PA behavior by means of mHealth (69%). Most of the studies were carried out on young-adult samples, with only three studies in older adults. Women were included in 60% of studies, and healthy people in 82%. The studies lasted between 1 and 7 days in 57.9%, and between three and seven assessments per day were carried out in 37%. The most popular topics evaluated together with PA were psychological state and social and environmental context. CONCLUSIONS: We have classified the EMA methodologies used for assessing PA behaviors. A total of 71% of studies used the term "EMA" and 51.3% used mHealth technology. Accelerometers have been the main built-in sensor used for collecting PA. The change of trend in the use of tools for EMA in PA coincides with the technological advances of the last decade due to the emergence of smartphones and mHealth technology. There is enough evidence to use the term mEMA when mHealth technology is being used for monitoring real-time lifestyle behaviors in natural situations. We define mEMA as the use of mobile computing and communication technologies for the EMA of health and lifestyle behaviors. It is clear that the use of mHealth is increasing, but there is still a lot to be gained from taking advantage of all the capabilities of this technology in order to apply EMA to PA behavior. Thus, mEMA methodology can help in the monitoring of healthy lifestyles under both subjective and objective perspectives. The tendency for future research should be the automatic recognition of the PA of the user without interrupting their behavior. The ecological information could be completed with voice messages, image captures or brief text selections on the touch screen made in real time, all managed through smartphone apps. This methodology could be extended when EMA combined with mHealth are used to evaluate other lifestyle behaviors.

Changes in the Association between European Workers' Employment Conditions and Employee Well-being in 2005, 2010 and 2015.

The aim of this paper is to study whether there is a change in the association between employment conditions and European employees' well-being at three different time points (the years 2005, 2010 and 2015), characterized by different socio-economic contexts. We based our study on the European Working Conditions Survey. Logistic regressions were performed by adjusting for gender, age, level of education, seniority, occupation, establishment size, activity sector and economic activity. Adjusted odds ratios (ORadj) and 95% confidence intervals (95% CI) are reported. In general, the association between employment conditions (type of employment contract, supervising, weekly working hours, long working hours, other paid jobs, working at weekends or doing shifts) and well-being indicators (anxiety, fatigue and dissatisfaction) seemed to continue being harmful, or had even changed for the worse since 2005. The paper briefly discusses the possible reasons for this situation and calls for future research on the relation between well-being and irregular type of contracts, self-employment, supervising others or hours worked per week. Some implications in public health policies are also discussed.

Central sensitization in knee osteoarthritis and fibromyalgia: Beyond depression and anxiety.

OBJECTIVES: To determine the psychopathological profile of patients with central sensitization (CS) in a sample of knee osteoarthritis, with and without CS, and fibromyalgia, and to compare their psychopathological profiles. METHODS: The final sample consists of 19 patients with osteoarthritis and CS (mean 66.37 years ± 8.77), 41 osteoarthritis patients without CS (mean 66.8 ± 7.39 years), 47 fibromyalgia patients (mean 46.47 years ± 7.92) and 26 control subjects (mean 51.56 years ± 11.41). The psychopathological profile was evaluated with the Millon Multiaxial Clinical Inventory. RESULTS: The average score of MCMI-III reflect higher scores in the fibromyalgia and osteoarthritis-CS groups. Patients with osteoarthritis-CS are more likely to report larger scores in Borderline and Major Depression scales. Fibromyalgia patients are more likely to report more increased scores in Somatoform and Major Depression, versus osteoarthritis-CS group. Fibromyalgia patients versus osteoarthritis without CS are more likely to report higher scores in Schizoid, Depression, Histrionic, Sadistic, Borderline, Somatoform, Posttraumatic Stress Disorder and Major Depression scales. DISCUSSION: Patients with CS have less differences in their psychopathological profiles as well as in both osteoarthritis groups and greatest differences are obtained between the fibromyalgia and osteoarthritis without CS, so perhaps presence of CS is the key to differentiate those groups and not chronic pain. An exhaustive assessment brings more accurate psychopathological profiles, thus better psychological treatment could be applied.

Method effects associated with negatively and positively worded items on the 12-item General Health Questionnaire (GHQ-12): results from a cross-sectional survey with a representative sample of Catalonian workers.

OBJECTIVE: Recent studies into the factorial structure of the 12-item version of the General Health Questionnaire (GHQ-12) have shown that it was best represented by a single substantive factor when method effects associated with negatively worded (NW) items are considered. The purpose of the present study was to examine the presence of method effects, and their relationships with demographic covariates, associated with positively worded (PW) and/or NW items. DESIGN: A cross-sectional, observational study to compare a comprehensive set of confirmatory factor models, including method effects associated with PW and/or NW items with GHQ-12 responses. SETTING: Representative sample of all employees living in Catalonia (Spain). PARTICIPANTS: 3050 participants (44.6% women) who responded the Second Catalonian Survey of Working Conditions. RESULTS: A confirmatory factor analysis showed that the best fitting model was a unidimensional model with two additional uncorrelated method factors associated with PW and NW items. Furthermore, structural equation modelling (SEM) revealed that method effects were differentially related to both the sex and age of the respondents. CONCLUSION: Individual differences related to sex and age can help to identify respondents who are prone to answering PW and NW items differently. Consequently, it is desirable that both the constructs of interest as well as the effects of method factors are considered in SEM models as a means of avoiding the drawing of inaccurate conclusions about the relationships between the substantive factors.

Tools to assess the measurement properties of quality of life instruments: a meta-review protocol.

INTRODUCTION: Using specific tools to assess the measurement properties of health status instruments is recommended both to standardise the review process and to improve the methodological quality of systematic reviews. However, depending on the measurement standards on which these tools are developed, the approach to appraise the measurement properties of instruments may vary. For this reason, the present meta-review aims to: (1) identify systematic reviews assessing the measurement properties of instruments evaluating health-related quality of life (HRQoL); (2) identify the tools applied to assess the measurement properties of HRQoL instruments; (3) describe the characteristics of the tools applied to assess the measurement properties of HRQoL instruments; (4) identify the measurement standards on which these tools were developed or conform to and (5) compare the similarities and differences among the identified measurement standards. METHODS AND ANALYSIS: A systematic review will be conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols Guidelines. Electronic search will be carried out on bibliographic databases, including PubMed, Cumulative Index to Nursing and Allied Health Literature, Psychological Information, SCOPUS, Web of Science, COSMIN database and ProQuest Dissertations & Theses Global, being limited by time (2008-2018) and language (English). Descriptive analyses of different aspects of tools applied to evaluate the measurement properties of HRQoL instruments will be presented; the different measurement standards will be described and some recommendations about the methodological and research applications will be made. ETHICS AND DISSEMINATION: Ethical approval is not necessary for systematic review protocols. The results will be disseminated by its publication in a peer-reviewed journal and presented at a relevant conference. PROSPERO REGISTRATION NUMBER: CRD42017065232.

Three risk of bias tools lead to opposite conclusions in observational research synthesis.

OBJECTIVES: The aim of this study was to assess the agreement and compare the performance of three different instruments in assessing risk of bias (RoB) of comparative cohort studies included in a health psychology meta-analysis. STUDY DESIGN AND SETTING: Three tools were applied to 28 primary studies included in the selected meta-analysis: the Newcastle-Ottawa Scale, quality of cohort studies (Q-Coh), and risk of bias in nonrandomized studies of interventions (ROBINS-I). RESULTS: Interrater agreement varied greatly from tool to tool. For overall RoB, 75% of the studies were rated as low RoB with the Newcastle-Ottawa Scale, 11% of the studies with Q-Coh, and no study was found to be at low RoB using ROBINS-I. No influence of quality ratings on the meta-analysis results was found for any of the tools. CONCLUSION: Assessing RoB using the three tools may lead to opposite conclusions, especially at low and high levels of RoB. Domain-based tools (Q-Coh and ROBINS-I) provide a more comprehensive framework for identifying potential sources of bias, which is essential to improving the quality of future research. Both further guidance on the application of RoB tools and improvements in the reporting of primary studies are necessary.

Benefits of the humidified low-flow oxygen therapy in infants with mild-moderate bronchiolitis.

AIMS AND OBJECTIVES: To investigate the clinical benefits of using humidification in low-flow oxygen therapy. Specific objectives were to investigate via an assessment of the number of nasal lavages whether humidification can help to decrease the nasal mucus viscosity, to determine whether it can relieve feeding difficulties by comparing the weight gain in infants, to ascertain whether it can relieve respiratory distress by assessing the heart and respiratory rates and contribute to improved clinical outcomes, measured by the length of stay and oxygen requirements. BACKGROUND: There is no evidence to support the use of humidification in low-flow oxygen therapy as a usual clinical practice in the management of bronchiolitis. DESIGN: A controlled quasi-experimental study. METHODS: A total of 97 infants were included, aged ≤6 months, with bronchiolitis, low-flow oxygen therapy and bronchodilators nebulised with hypertonic saline 3%. Data from the control group (nonhumidified) were gathered from 2010-2012 (49 infants), and data from the group with humidification from 2012-2014 (48 infants). Linear and Poisson regressions were performed adjusting for relevant characteristics of patients. RESULTS: Humidification was shown to be associated with significant reductions in the number of nasal lavages in infants with Sant Joan de Déu Bronchiolitis Scores of BROSJOD≤7, in the heart rate of infants with mixed bronchodilators treatment, and in the length of stay and oxygen requirements of infants with Score BROSJOD≤5. No differences in weight and respiratory rate were found. CONCLUSIONS: Humidification in low-flow oxygen therapy is an effective nursing intervention to improve the clinical outcomes of infants with mild-moderate bronchiolitis. RELEVANCE TO CLINICAL PRACTICE: Humidifying the nasal mucosa can help to reduce the need for professional procedures, oxygen requirements and hospitalisation length. Further research into the economic savings involved is recommended.

Instruments to assess patient comfort during hospitalization: A psychometric review.

AIM: To analyse the psychometric properties and the utility of instruments used to measure patient comfort, physical, social, psychospiritual and/or environmental, during hospitalization. BACKGROUND: There are no systematic reviews nor psychometric reviews of instruments used to measure comfort, which is considered an indicator of quality in health care associated with quicker discharges, increased patient satisfaction and better cost-benefit ratios for the institution. DESIGN: Psychometric review. DATA SOURCES: MEDLINE, CINAHL, PsycINFO, Web of Knowledge, ProQuest Thesis&Dissertations, Google. REVIEW METHODS: We limited our search to studies published between 1990-2015. The psychometric analysis was performed using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN), along with the Quality Criteria for Measurement Properties. The utility of the instruments was assessed according to their cost-efficiency, acceptability and educational impact. Protocol registration in PROSPERO, CRD42016036290. RESULTS: Instruments reviewed showed moderate methodological quality and their utility was poorly reported. Thus, we cannot recommend any questionnaire without reservations, but the Comfort Scale, the General Comfort Questionnaire and their adaptations in adults and older patients, the Psychosocial Comfort Scale and the Incomfort des Patients de Reanimation are the most recommendable instruments to measure comfort. CONCLUSIONS: The methodology of the studies should be more rigorous and authors should adequately report the utility of instruments. This review provides a strategy to select the most suitable instrument to assess patient comfort according to their psychometric properties and utility, which is crucial for nurses, clinicians, researchers and institutions.

Methodological quality is underrated in systematic reviews and meta-analyses in health psychology.

OBJECTIVES: In this paper, we compile and describe the main approaches proposed in the literature to include methodological quality (MQ) or risk of bias (RoB) into research synthesis. We also meta-review how the RoB of observational primary studies is being assessed and to what extent the results are incorporated in the conclusions of research synthesis. STUDY DESIGN AND SETTING: Electronic databases were searched for systematic reviews or meta-analyses related to health and clinical psychology. A random sample of 90 reviews published between January 2010 and May 2016 was examined. RESULTS: A total of 46 reviews (51%) performed a formal assessment of the RoB of primary studies. Only 17 reviews (19%) linked the outcomes of quality assessment with the results of the review. CONCLUSION: According to the previous literature, our results corroborate the lack of guidance to incorporate the RoB assessment in the results of systematic reviews and meta-analyses. Our recommendation is to appraise MQ according to domains of RoB to rate the degree of credibility of the results of a research synthesis, as well as subgroup analysis or meta-regression as analytical methods to incorporate the quality assessment.
