Health Protection and Promotion of Sign Language Interpreters Through Implementation of Total Worker Health®

Study Overview
=================
Brief Summary
-----------------
Using mixed-methods and a clinical efficacy trial design, the overall objective of this study will employ implementation strategies to adapt and evaluate a previous integrated Total Worker Health® (TWH®) program and pilot test its efficacy on sign language interpreter well-being. The central hypothesis is that interpreters in the health protection and promotion program (intervention) will demonstrate significantly improved well-being compared to those in a general health program (control).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Health Protection and Promotion Program<br> | Behavioral: Health Protection and Promotion<br>* An adaptive integrated Total Worker Health® program. Virtual 8-week program that's been contextualized to the physical and mental health needs of sign language interpreters. It will examine biomechanics, sleep hygiene, vicarious trauma and burnout, demand-control schema, physical activity, emotional management strategies, proper nutrition and examination of worksite.<br>|
| Active Comparator: General Health Program<br> | Behavioral: General Health Program<br>* Virtual 8-week program that addresses participant sleep hygiene, physical activity and proper nutrition.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| mean change in acceptability using the Training Acceptability Rating Scale-1 (TARS-1) | TARS-1 measures acceptability using six items (1=strongly disagree; 6=strongly agree) and demonstrates good test-retest reliability, internal consistency, and construct and concurrent validity. The scale ranges from 6 to 36 with higher scores indicating better acceptability. | 15 to 24 months | 
| mean change in acceptability using the Training Acceptability Rating Scale-2 (TARS-2) | TARS-2 assesses perceived impact with eight items (0=not at all; 3=a great deal) and demonstrates good face and concurrent validity. Of particular interest, TARS-2 also includes three qualitative items asking about the most helpful part of the program and any recommended changes and invites other comments. The scale ranges from 0-24 with higher scores indicating better outcomes. | 15 to 24 months | 
| mean change in Acceptability, Feasibility, and Appropriateness Scale | This acceptability (six items), feasibility (three items), and appropriateness (five items) instrument will be used to assess whether or not the intervention efforts were successful. The 14 total items across three subscales demonstrate good to excellent internal consistency and are rated on a five-point scale (1=not at all; 5=extremely). High scores of 30, 15, and 25 and low scores of 6, 3, and 5 indicate excellent and poor acceptability, feasibility, and appropriateness, respectively. | 15 to 24 months | 
| mean change in the National Institute of Occupational Safety and Health's Worker Well-Being Questionnaire- work evaluation and experience | Work evaluation and experience is the first of five domains in this comprehensive measure of worker well-being and has 16 total questions. Total summed scores within this section range from 23-128 with higher scores indicating better outcomes (accounting for inverse scoring on negative items). | baseline to post intervention (approximately 15-24 months) | 
| mean change in the National Institute of Occupational Safety and Health's Worker Well-Being Questionnaire- work evaluation and experience | Work evaluation and experience is the first of five domains in this comprehensive measure of worker well-being and has 16 total questions. Total scores within this section range from 23-128 with higher scores indicating better outcomes (accounting for inverse scoring on negative items). | baseline to 6 months post intervention (approximately 21-30 months) | 
| mean change in the National Institute of Occupational Safety and Health's Worker Well-Being Questionnaire- workplace policies and culture | Workplace policies and culture is the second of five domains in this comprehensive measure of worker well-being and has 14 total questions. Total scores within this section range from 12-75 with higher scores indicating better outcomes (accounting for inverse scoring on negative items). | baseline to post intervention (approximately 15-24 months) | 
| mean change in the National Institute of Occupational Safety and Health's Worker Well-Being Questionnaire- workplace policies and culture | Workplace policies and culture is the second of five domains in this comprehensive measure of worker well-being and has 14 total questions.

| mean change in the National Institute of Occupational Safety and Health's Worker Well-Being Questionnaire- workplace physical environment and safety climate | Workplace physical environment and safety climate is the third of five domains in this comprehensive measure of worker well-being and has 10 total questions. Total scores within this section range from 14-60 with higher scores indicating better outcomes (accounting for inverse scoring on negative items). | baseline to post intervention (approximately 15-24 months) |

| mean change in the National Institute of Occupational Safety and Health's Worker Well-Being Questionnaire- health status | Health status is the fourth of five domains in this comprehensive measure of worker well-being and has 23 total questions. There are five open text box items within this section (i.e. asking for the number of days the respondent gets high intensity physical activity). Otherwise, total scores of the Likert scale items within this section range from 24-146 with higher scores indicating better outcomes (accounting for inverse scoring on negative items). | baseline to post intervention (approximately 15-24 months) |

| mean change in the National Institute of Occupational Safety and Health's Worker Well-Being Questionnaire- home, community, and society | Home, community, and society is the final domain in this comprehensive measure of worker well-being and has 5 total questions. Total scores within this section range from 11-65 with higher scores indicating better outcomes (accounting for inverse scoring on negative items). | baseline to post intervention (approximately 15-24 months) |
