Work-related musculoskeletal disorders are some of the most prevalent diseases in the world. They have a multifactorial aetiology encompassing ergonomic and psychosocial risk factors. The aim of this study is to analyse the way job insecurity and physical workload are linked to musculoskeletal disorders, as well as the mediating role other psychosocial work risks can have on this potential relationship. A parallel mediation path regression analysis was designed using a sample of 457 nursing aides. The influence job insecurity and physical workload has on the onset of musculoskeletal symptoms together with the variables which mediate this relationship were examined. The results prove that both independent variables explain the onset of musculoskeletal symptoms in these professionals. The influence exerted by job insecurity is mediated by the social support received at work and the demands of the job. However, when analysing the physical workload, the social support received at work is not relevant as a mediator in this relationship. Job insecurity and physical workload are significant variables on the occurrence of musculoskeletal symptoms. The data obtained supports the need to focus on physical and psychosocial factors in order to prevent these disorders.

The aim of this study is to translate, culturally adapt, and validate a Spanish version of the Nordic Musculoskeletal Questionnaire for a sample of nursing assistant aides. The questionnaire was translated and culturally adapted. Next, it was included in a battery of tests that was completed by 526 nursing assistants working in residential care homes in the Principality of Asturias (Spain). To assess its validity, the Exploratory Factor Analysis and the Confirmatory Factor Analysis were used. The internal consistency was estimated with McDonald's Omega coefficient (?), complemented by the test-retest reliability analysis through the intraclass correlation coefficient. The validity of the criteria was established by the correlation between total score on the test and quality of life measures, job insecurity and psychological demand, and social support at work. The Exploratory Factor Analysis and Confirmatory Factor Analysis adjustment indices confirmed it is a unidimensional test. The internal consistency values indicated very high reliability (? = 0.81). Similarly, the intraclass correlation coefficient showed statistically significant values and an excellent correlation coefficient (r = 0.95). The validity of the criteria showed a statistically significant correlation with all the constructs studied, particularly with quality of life. This Spanish version of the Nordic Musculoskeletal Questionnaire has good psychometric qualities for a population of nursing aides and therefore may be a valid and reliable tool for assessing musculoskeletal disorders.

A number of studies analyze the link between the presence of psychosocial risk factors and work‐related musculoskeletal disorders. The increase in job insecurity (JI) has resulted in a growing focus on its likely role as a risk factor within occupational health. Accordingly, the aim of this research was to carry out a systematic review of studies that include JI among the relevant risk factors, specifically drawing data from this variable to observe the significance of its association with musculoskeletal disorders (MSDs). For this purpose, a literature search was carried out: from a sample of 859 studies found and 23 were selected after applying the eligibility criteria. Fifteen studies (65.2% of the selection) presented statistically significant results regarding the link between JI and MSDs: the upper limbs and back were the body areas most affected by this association. In sum, JI should be considered a potential precursor of MSDs. Therefore, further study on this psychosocial risk and its association with these types of pathologies is necessary.

Aim: To analyse the effectiveness of an active ageing intervention modality through peer mentoring.Design: A quasi‐experimental research study is carried out through three groups, one control (educational workshops on active ageing given by professionals) and two experimental (workshops given by peers with digital or face‐to‐face exposure).Methods: All groups share duration (7 weeks) and content, modifying the route of exposure. The effectiveness of the model is measured through the variables of physical health, mental health and social support. Loneliness and the need for care are also controlled for.Results: The total sample consists of n = 209 people aged over 60 living in a rural context, of which n = 12 form the volunteer/mentor group. Active ageing interventions show an improvement in the perception of physical and mental health among people in need of some form of care, with all three modalities being equally effective. The impact on social support is analysed by controlling for the loneliness and social participation variable; in these cases, the face‐to‐face experimental group of peers is more effective than the others.Conclusions: The peer‐to‐peer methodology is as effective as the traditional methodology with a practitioner in maintaining and improving health perception, and the face‐to‐face methodology with peers is more useful in fostering social support among people experiencing loneliness.Implications for the Profession and/or Patient Care: Peer mentoring is presented as a good strategy to improve social support for older people and to combat loneliness.Impact: To address the prevention of dependency through the promotion of active ageing. Peer mentoring is confirmed to have a significant impact on social support and could be a socio‐educational tool applicable to older people experiencing loneliness.Reporting Method: This study has adhered to JBI guidelines. JBI critical appraisal checklist for quasi‐experimental studies has been used.Patient or Public Contribution: Volunteer mentors contributed to the design and delivery of the workshops.

To analyse the link between Musculoskeletal Disorders (MSDs) and certain psychosocial risk factors in the context of geriatric nursing aides. To explore social support at work as a mediating variable between other psychosocial risks and the onset of musculoskeletal symptoms. A cross-sectional observational study was carried out. Data from a sample of 526 nursing aides working in 35 residential centres for the elderly of a Spanish region were collected. Validated scales such as the Nordic Musculoskeletal Questionnaire and Job Content Questionnaire were used to measure prevalence of musculoskeletal disorders and different psychosocial risks (psychological demand, social support from supervisors and peers, control over work). A parallel mediation analysis was carried out to determine the mediating role of social support at work on the relationship between the psychological job demands and MSDs. Psychological demand and social support at work were significantly linked (U = 17,792; U = 18,766, p < .001) to musculoskeletal health.The results from the parallel mediation analysis showed that the indirect effect of the psychological demand on MSDs via social support form supervisors was also statistically significant (β = 0.079; CI = 0.034; 0.137) but not so in the case of social support from peers (β= - 0.008; CI= - 0.041; 0.010). Psychological demand and social support are risks significantly associated with musculoskeletal health. Social support received from supervisors acts as a protective factor against MSDs in workers with high-demand jobs. However, social support from peers does not have a significant effect on the model proposed.
