Abstract
We pilot a stress management intervention based on Cognitive Behavioral Therapy (CBT) to understand whether building skills to cope with psychological strain raises productivity and well-being levels among female workers in an urban manufacturing context. The setting is the Bangladesh ready-made garment (RMG) sector, the country’s largest employer of low-skilled workers living in urban slums and squatter settlements. Residing in these areas exposes them to high levels of noise, waste accumulation, air pollution and other distressing environmental conditions. In addition, the majority migrate from rural areas, losing access to family support and social networks. This study will use a randomized placebo-controlled trial to ascertain whether a stress reduction intervention can pay for itself through increased productivity and reduced absenteeism in factories. We will also measure its effects on the levels of stress hormone cortisol and on self-reported symptoms of anxiety and depression.

Interventions
Intervention(s)
We evaluate the impact of a widely recognized stress reduction intervention (Cognitive Behavioral Therapy, CBT) on workers’ mental health and job performance in the garment industry in Bangladesh. CBT is one of the most extensively researched and empirically supported forms of psychotherapy and has proven highly effective for treating anxiety disorders, stress and depression when compared to placebo therapies (Farrand and Woodford, 2013; Hofmann and Smits 2008, Butler at al., 2006). This form of psychotherapy is intended to build life skills and break self-reinforcing cognitive and behavioral biases that maintain worrying and stress. It relies on highly standardized cognitive exercises (handouts, worksheets etc.) and behavioral exercises (e.g. muscular relaxation training) to teach individuals how to develop adequate coping strategies. Both treated and control individuals will receive one-hour of therapy, once per week, over a 10 week period.

Primary Outcomes
Primary Outcomes (end points)
We will collect data on individual productivity, absenteeism and turnover continuously for a period of 5 months, in order to span the whole intervention period (3 months) and the 4 weeks preceding and following each wave. We will also measure the levels of stress, anxiety and depression two times (baseline and immediately after the intervention finishes) using two self-assessment scales. The first is a version of the State-Trait Anxiety Inventory that has already being adapted to the local context in a previous pilot study. The second is a combination of the GAD-7 and PHQ-9 questionnaires. All these instruments have been extensively used to monitor anxiety and depressive symptoms by mental health services and general practitioners in different countries. In addition, we will apply a Daily Hassle Scale that will allow us to identify the type and frequency of problems causing stress. Finally, with the aim of validating the self-reported data, we will measure the levels of cortisol, a widely used biomarker for stress, by collecting two rounds of saliva samples (before and after receiving the treatment).

Experimental Design
Experimental Design
We will use a randomized placebo-controlled trial. We will use a sample of 300 female workers from 3 garment factories (i.e. 100 workers per factory) in Dhaka. In each factory, 50 workers will be randomly selected to receive Cognitive Behavioral Therapy and the other 50 will receive a placebo intervention.
