NCT05199415

Brief Summary

This study seeks to evaluate how work conditions affect workers' health and well-being, job attitudes and decisions on the job, and key organizational outcomes. This study is being carried out in partnership with a national retailer's e-commerce division. The study centers on a cluster randomized trial evaluation of changes in workplace policies and practices in order to understand their impact on workers, families, and the firm but also utilize multi-method data to gain a better understanding of the stressors and sources of resilience for this growing, but understudied population of low-wage workers.

Outcome Measures

Primary Outcomes (1)

  • Psychological Distress

    The frequency of non-specific psychological distress (e.g., feeling nervous, hopeless, restless or fidgety, depressed, worthless, and everything is an effort) experienced in the last 30 days. This outcome will be measured using the Kessler Distress Scale. Respondents report the frequency from 0 (none of the time) to 4 (all of the time). Items are summed to give a score between 0 and 24, with higher scores indicating higher levels of psychological distress.

    12 Months

Secondary Outcomes (5)

  • Psychological well-being

    12 Months

  • Self-reported general health

    12 Months

  • Injuries and injuries reported to management

    12 Months

  • Musculoskeletal pain

    12 months

  • Sleep duration

    12 months

Study Arms (2)

HaWC Intervention

EXPERIMENTAL

These are the buildings that are randomized to receive the intervention during the study period.

Behavioral: Health and Well-being Committee

Control

NO INTERVENTION

These are the buildings that are randomized to continue as normal (no intervention) during the study period.

Interventions

Health and Well-being Committees (HaWCs) will be introduced in treatment sites as a means to facilitate on-going problem identification and collaborative processes for developing action plans, implementing small-scale, site-based improvements. HaWCs will involve 10-14 workers and frontline supervisors, with a worker and manager co-chair. HaWCs will identify challenges to safety, health, and well-being spanning physical hazards, COVID-19 protocols as relevant, other conditions of work (e.g., schedules, pace of work), and policies (e.g., absenteeism, performance management). They will then design and implement mitigating solutions and track outcomes. As such, HaWCs have a broader scope than traditional safety committees and will actively solicit worker voice regarding policies and practices that are not labeled as health and safety policies.

HaWC Intervention

Data Sharing

IPD Sharing
Will share

For the Fulfillment Center Intervention Study, administrative data are made available through a data use agreement with the firm; therefore, the investigators will be unable to make these data publicly available. Additionally, qualitative data will not be made public as it may be impossible to adequately de-identify these elements because of site-specific details and reflections in the interviews and focus groups. To protect confidentiality of these nested data (with employee survey responses nested in work sites), de-identified survey data will be available to researchers through a restricted data access process.

Shared Documents
STUDY PROTOCOL, ANALYTIC CODE
Time Frame
It is expected that survey data for the Fulfillment Center Intervention Study will be available through the restricted access process described below no later than the acceptance for publication of the main findings from the final dataset.
Access Criteria
Those who wish to use the data will need to complete an application with their affiliate institution and Institutional Review Board and provide a brief description of their project. The data sharing agreement will state that a) the data access will last for one year, with the opportunity to extend on a case-by-case basis, b) those who use the datasets will do so only for research or statistical purposes and not for investigation of the research subjects, c) published data will include the appropriate acknowledgement as stated in the data documentation, and d) the data will not be distributed to anyone other than the approved researcher.
