Psychometric properties of the generalized anxiety disorder-7 (GAD-7) in a sample of workers

Fourteen-item perceived stress scale assessment using item response theory among pregnant women

The current study aimed to assess the psychometric properties of the Spanish language version of the 14-item Perceived Stress Scale (PSS-S) in a population of pregnant women who speak Spanish in Peru using item response theory (IRT). Our study consisted of 5,435 pregnant women who participated in the Pregnancy Outcomes Maternal and Infant Study (PrOMIS) cohort in Peru. Exploratory and confirmatory factor analyses were conducted to determine dimensionality of the scale in this population, and item response theory was conducted to determine the applicability of the PSS. The PSS consisted of a 2-factor questionnaire measuring perceived stress and coping capacity accounting for 77% of variability. The IRT analysis showed differences in item difficulty and discrimination. Item difficulty represents the level of the latent construct where 50% of respondents endorse a particular response, and item discrimination determines the rate of change of the probability of endorsing an item for differing ability levels. For the first factor, perceived stress, item 12 was the least difficult and item 2 was the most difficult. For the second factor, coping capacity, item 9 was the least difficult and item 6 was the most difficult. The Spanish version of the 14-item PSS can be a useful assessment tool for perceived stress, but more IRT should be done to delve further into the psychometric properties of the questionnaire to inform clinicians and policy makers more appropriately.

The Web-Based Pain-at-Work Toolkit With Telephone Support for Employees With Chronic or Persistent Pain: Protocol for a Cluster Randomized Feasibility Trial

BACKGROUND

Chronic or persistent pain affects one's ability to work or be productive at work, generating high societal and economic burden. However, the provision of work-related advice and support for people with chronic pain is variable or lacking. The Pain-at-Work (PAW) Toolkit was cocreated with people who live with pain, health care professionals, and employers. It aims to increase knowledge about employee rights and how to access support for managing a painful chronic condition in the workplace and provides advice on lifestyle behaviors that facilitate the management of chronic pain.

OBJECTIVE

We aimed to establish the feasibility of conducting a definitive cluster randomized controlled trial comparing access to the PAW Toolkit and telephone support calls from an occupational therapist (PAW) with treatment as usual (ie, standard support from their employer). Our primary outcomes are establishing parameters of feasibility, acceptability, usability, and safety of this digital workplace health intervention. We will assess the candidate primary and secondary outcomes' feasibility and test research processes for a definitive trial.

METHODS

This is an open-label, parallel 2-arm pragmatic feasibility cluster randomized controlled trial with exploratory health economics analysis and a nested qualitative interview study. We aim to recruit 120 participants from at least 8 workplace clusters (any type, >10 employees) in England. The recruitment of workplaces occurs via personal approach, and the recruitment of individual participants is web based. Eligible participants are vocationally active adults aged ≥18 years with internet access and self-reporting chronic pain interfering with their ability to undertake or enjoy productive work. A restricted 1:1 cluster-level randomization is used to allocate employment settings to PAW or treatment as usual; participants are unblinded to group allocation. Following site- and individual-level consent, participants complete a web-based baseline survey (time 0), including measures of work capacity, health and well-being, and health care resource use. Follow-up is performed at 3 months (time 1) and 6 months (time 2). Feasibility outcomes relate to recruitment; intervention fidelity (eg, delivery, reach, uptake, and engagement); retention; and follow-up. Qualitative evaluation (time 2) is mapped to the Capability, Opportunity, Motivation-Behavior model and will explore intervention acceptability to employees and employers, along with individual and contextual factors influencing the delivery and uptake of the intervention.

RESULTS

Ethics approval was obtained in March 2023. Trial recruitment began in June 2023.

CONCLUSIONS

The PAW Toolkit is the first evidence-based digital health intervention aimed at supporting the self-management of chronic or persistent pain at work. This study will inform the design of a definitive trial, including sample size estimation, approaches to cluster site identification, primary and secondary outcomes' selection, and the final health economic model. Findings will inform approaches for the future delivery of this digital health intervention.

ietanti-flamatoria or DAIN: A Crohn's disease management strategy tailored for Puerto Ricans

Diet has been increasingly shown to be of therapeutic benefit for patients with inflammatory bowel diseases (IBD), especially Crohn's disease (CD). Yet dietary guidelines are nonexistent. Moreover, diets tailored to Puerto Ricans with IBD living on the island, have not been developed and tested. The rising prevalence of IBD in Puerto Rico warrants exploring the use of diet as part of the treatment strategies for these patients [1]. Here, we describe the study design of "Dieta Anti-Inflamatoria" or DAIN, a parallel two-arm randomized pilot trial aiming at testing the efficacy of IBD-Anti-inflammatory diet (IBD-AID) adapted for adults with CD living in Puerto Rico (clinical trial registration number: NCT05627128). We tailored the IBD-AID to the local cuisine preferences and food availability by creating and adapting recipes consistent with the IBD-AID principles [2,3]. In focus groups with a Community Research Advisory Panel and one-on-one consultations with implementation experts, we identified several aspects of the intervention to adapt before the implementation. The objectives of the stakeholder/expert-informed adaptation were to improve feasibility and compliance while developing the culturally tailored dietary intervention. DAIN was designed for adults living in Puerto Rico with CD and geared to be affordable, appropriate, and acceptable for patients with mild-to-moderate CD. The significance of this work is the validation of culturally appropriate nutritional guidelines to help manage CD symptoms. DAIN provides a blueprint for a comprehensive nutritional program that can be adapted to regional preferences and local food availability allowing wider implementation of diet as an adjunct treatment in diverse clinical settings.
