- Brief Summary
The primary purpose of this hybrid Type II comparative effectiveness and implementation study is to compare two self-management strategies in nursery and landscape workers. This randomized pragmatic study will compare interventions with different degrees of support to determine if self-management videos plus multimodal personalized support is more effective than self-management videos alone for improving LBP among horticulture workers. Both groups will review short self-management video modules to introduce general pain concepts and the importance of managing pain without medication, risks of opioid use, self-management of pain, and simple ergonomic strategies for both groups. Both groups will choose 1 self-management strategy to manage pain at home and 1 ergonomic workplace strategy to limit pain. The video+support group will receive 1) check-list guidance, 2) review videos of their work tasks, and 3) receive text reminders to support implementation. Surveys will include instruments reflecting low back pain disability, pain, work ability, and affective or cognitive characteristics (self-efficacy, pain anxiety, depression, coping), collected at baseline, pre- and post-intervention, with follow-ups at 3- and 6-months. Workers will be videoed pre- and post-intervention for calculation of work risk and to compare any changes after the intervention. Specific aim 2 will identify contextual factors impacting engagement, adoption, effectiveness, and implementation. Interviews, focus groups, and field notes will be used to explain results and establish patterns to inform future translation.
- Detailed Description
Primary dependent variables will be collected at all measurement points: pain severity, interference, and persistence, pain with specific work tasks, disability, work ability, and pain medication use. Affective or cognitive characteristics potentially impacting adoption and effectiveness (secondary dependent variables or confounders) such as coping, fear, anxiety, depression, will also be collected.The post- and follow-up survey questions will also reflect adoption, opinions of interventions, effectiveness, facilitators, and barriers.

Group Intervention Description Self-management videos + Multimodal personalized support Check lists for ergonomic options Participants will review short video modules on pain self-management without medication and ergonomic work adjustment and select 1 self-management option and 1 ergonomic option to use for 10 weeks. Participants will use 1) checklists to guided choices for strategies based on their self-identified most difficult work activities due to pain and options that they are not using regularly, 2) review video recordings of their own work movements to assist with ergonomic problem-solving and 3) receive text message reminders Self-management videos + Multimodal personalized support Text reminders Participants will review short video modules on pain self-management without medication and ergonomic work adjustment and select 1 self-management option and 1 ergonomic option to use for 10 weeks.

- Primary Outcome Measures
Name Time Method Pain Interference 1 year Extent of pain interference with work activities in the past week, 0=not at all, 100=prevented working at normal level, lower scores reflect less interference
Pain impact 1 year 2 items with 5 point scale recording impact on work activities and social activities ranging from never to always, with lower scores reflecting less impact
Pain frequency 1 year Number of days in the past week pain is experienced ranging from 0-7
Pain persistence 1 year Pain in the past 3 months reported on a 5 item scale ranging from not at all to pain every day without a break.
Adoption 1 year Use of the interventions reported for each work or self-management strategy selected (number of days used in the past week, how often used (never, occassionally, consistently) Higher scores and consistently are optimal
Numeric Pain Rating Severity 1 year Severity of pain reported for the past week and for the 3 most difficult work activities 0=no pain, 100=worst imaginable pain, lower scores reflect lower pain
Roland Morris Disability Index 1 year Disability Index for functional difficulties related to low back pain scored from 0-24 with low scores indicating lower disability
Difficulty with work tasks 1 year Patient Specific Functional Scale reported for 3 most difficult work activities with subscales reported on a scale of 0= no difficulty, 100=unable to perform with the average of the 3 items used for analysis.
Work ability 1 year Work Ability short form is reported on numeric rating scale from 0 (completely unable to work) to 10 able to work at your best
Use of medication and substances 1 yeat Frequency of pain medication and substances for pain in past 3 months reported on a 4 item scale (never, 1-2 days, 3-4 days, 5-7 days) never is optimal. Items for alcohol, cannabis, tobacco, herbal products, acetaminophen, anti-inflammatories, muscle relaxants, opioids). Frequency of use per day on average also reported for a total estimate.
