Project Description

Summary: There is a high prevalence of stress in the logistics sector owing to very demanding, fast-paced and unpredictable tasks. Mindfulness-based programmes may reduce stress but require considerable practice. Our aim was to evaluate the feasibility and effectiveness of a shortened, workplace-adapted, mindfulness-based programme for the logistics sector (WA-MBP-LS) for the purpose of reducing stress. A non-randomized, two-arm, controlled trial was conducted. The WA-MBP-LS (n=32) consisted of 6 weekly 90-minute mindfulness sessions. The control group (n=36) attended a psycho-educational seminar. The Perceived Stress Scale (PSS) and Five Facets of Mindfulness Questionnaire (FFMQ) were measured at pre-test, post-test and 6-month follow-up. Differences between groups were evaluated using mixed-effects models. Qualitative methods were used to analyse implementation issues. A 64.2% reduction was observed between initial volunteers and actual participants. Attrition at 6-month follow-up was 45.6%. Participants attended a median of 5 sessions. Decreases in PSS favoured the WA-MBP-LS group at post-test and follow-up. FFMQ played a mediating role in reductions in PSS. Barriers were disinterest, lack of programming, work overload and job unattended. Facilitators were curiosity, timing, company facilities and audio recordings. The WA-MBP-LS was feasible and effective to reduce stress but more efforts to improve the practicalities of implementation would be desirable.

Scope of Project

Subject Terms: Mindfulness; feasibility; stress; workplace; WA-MBP-LS; logistics sector

Geographic Coverage: Spain

Universe: People who were working in the central delegation of a Spanish transport company in February 2018

Data Type(s): clinical data

Methodology

Response Rate: The study was integrated into a voluntarily training course to reduce stress that was offered by the human resources section to the 300 people who were working in the central delegation of a Spanish transport company in February 2018. A total of 190 workers agreed to participate in the study on the condition of being able to choose the group in which they would participate; thus, randomization was not viable.
From all of the volunteers who initially agreed to participate, a total of 122 workers did not complete the baseline assessment and were therefore excluded from the study. The participants were allowed to choose the group in which they wished to participate, with 32 of them included in the experimental group and 36 in the wait-list control group, for a total of 68 participants at baseline.

Sampling: Non-randomized, two-arm, waitlist-controlled feasibility trial.

Collection Mode(s): web-based survey

Scales: Psychological scales:
-Perceived Stress Scale (PSS): The scale is composed of 10 items asking about the frequency of thoughts and feelings experienced during the last month with a Likert-type scale with 5 response options, from 0 (‘never’) to 4 (‘very often’).

-Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS): It is a self-report questionnaire that is composed of 7 items that are ranked by a Likert-type scale from 1 (‘never’) to 5 (‘always’).

-Work Satisfaction Scale (WSS): It asks about 5 topics: the relationship with the superior, relationships with other workers, the level of assigned responsibility, acknowledgement obtained for work well done and attention to suggestions. The degree of satisfaction for each of these items is assessed using a Likert-type scale with 7 response options, from 1 (‘very unsatisfied’) to 7 (‘very satisfied’).

- Five Facet Mindfulness Questionnaire (FFMQ): Respondents indicate on a 5-point Likert-type scale the degree to which each item is true for them, from 1 (‘never true’) to 5 (‘always true’).

Socio-demographic variables: age, sex, relationship (yes, no), number of children, residence (urban, non-urban), level of education (primary, secondary, university), years of service, sick leave in the last year (yes, no), type of contract (temporary, permanent), income satisfaction (not satisfied, slightly satisfied, moderately satisfied, very satisfied), minutes of vigorous weekly physical activity, and mindfulness practice during the previous six months (yes, no).

Adaption of the ‘Credibility/Expectancy Questionnaire (CEQ): This scale comprises 6 items rated between 0 (‘not at all’) and 10 (‘very much’) and assesses how logical, successful, recommendable, useful, helpful and non-aversive the intervention is. The internal consistency for the total score (that ranges between 0 and 10).
