Clinical Trial Summary

The study aims to evaluate if enhancing the mental health of refugee mothers can make them better able to implement new farming methods that are meant to improve food security in the face of climate change. It is a cluster-randomized controlled trial involving 900 pairs consisting of refugee mothers and their children aged 36-59 months, living in Nakivale refugee settlement in Uganda. The mothers will be randomly assigned to one of three groups:

• Control group: Mothers will receive Enhanced Usual Care (EUC).

• HGI group: Mothers will receive the Home Gardening Intervention, consisting of training and supplies for home gardening.

• HGI/SH+ group: Mothers will receive both the Home Gardening Intervention and the Self-Help Plus mental health intervention.

The main goal is to see if the gardening program alone can reduce food insecurity after 12 months compared to the EUC control group. It also aims to see if reducing psychological distress by adding the mental health component boosts the effects of the gardening intervention.

Secondary goals are to look at impacts on dietary diversity, child malnutrition, and mothers' mental health levels across all three groups.

The study also gathers survey data on participant mothers' migration history, social capital, exposure to potentially traumatic events, exposure to natural hazards and environmental stressors, mental health, and parenting style. Both mothers and their children will furthermore play incentivized economic games to measure their economic preferences (time, risk, social preferences). Additionally, the study will assess childrens' wellbeing and functioning. Children will also be asked to carry out gamified tasks designed to measure their cognitive development.

Intervention

Behavioral:
• Home Gardening Intervention (HGI)
The Home Gardening Intervention (HGI) provides refugee participants with agricultural inputs and training (field prep., sowing, water management, pest control, weeding, etc.) through a participatory field school approach with a curriculum derived from best practices in agro-ecology. The program includes active monitoring during a 12-month period. The training involves nutrition education on cooking methods and the importance of dietary diversity using garden produce as well as guidance on surplus management and market support. The overall goal of the intervention is to enable climate-resilient farming for improved food security and dietary diversity that is sustainable long-term.
• Self-Help Plus (SH+)
Self-Help Plus (SH+) is a 5-session group intervention developed by the WHO and based on Acceptance and Commitment Therapy, delivered by trained local facilitators. It provides tools to manage stress and adversity through pre-recorded audio lessons and a self-help book. Sessions include individual exercises and group discussions. SH+ aims to decrease psychological distress. It has shown effectiveness among refugees in Uganda and elsewhere.
• Enhanced Usual Care (EUC)
The Enhanced Usual Care (EUC) control condition involves a single 15-minute psychoeducation session providing information on managing overthinking and utilizing available mental health services in the settlement. These services include psychosocial support from community health workers and clinical mental health services (counseling and medications) provided weekly at local primary care centers by a visiting team.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Economic preferences	Both mothers and their children will play a set of incentivized economic games to measure economic preferences. Risk-taking will be measured using a "bomb-task." Time preferences will be measured using an investment task. Prosociality will be assessed using a series of dictator games.	12 months
Other	Cognitive skills	Children's cognitive skills will be assessed using a battery of gamified tasks. Spatial cognition will be measured using 3d blocks and 2d shapes. Mathematics ability will be assessed using free counting, give-n, number comparison, and addition/subtraction tasks. Theory of mind will be measured using surprise content and surprise outcome tasks. Gaze following will be measured using TANGO. Language skills will be assessed using TIFALDI.	12 months
Other	Social capital	Social capital will be measured using survey items asking about group membership, involvement in citizenship activities, and trust.	12 months
Other	Positive parenting	Positive parenting will be assessed using the 6-item Positive Parenting Subscale of the Alabama Parenting Questionnaire (APQ). This subscale focuses on the frequency of positive interactions between parents and children. Each item is rated on a scale from 1 (never) to 5 (always), with higher scores indicating more frequent use of positive parenting practices.	12 months
Other	Maltreatment	Child maltreatment will be measured using the 11-Item Discipline Module of the Multiple Indicator Cluster Survey (MICS). MICS is a household survey developed by UNICEF. It consists of eleven Yes/No questions that inquire about the different disciplinary actions taken by the caregiver in the past month. The total score can range from 0 to 11, with higher scores indicating the use of more types of disciplinary actions.	12 months
Other	Posttraumatic stress	Posttraumatic stress will be measured using the Post-Traumatic Checklist 6-item Civilian Version (PCL-C). It has 6 items rated from 1 to 5, measuring key PTSD symptoms. Total score ranges from 6 to 30, with scores above 14 indicating potential PTSD.	12 months
Other	Stress	Stress will be assessed with the Perceived Stress Scale 4-item version (PSS-4). The PSS-4 is a brief self-report measure of perceived stress. It consists of four questions that ask about feelings and thoughts during the last month. Each item is rated on a scale from 0 (Never) to 4 (Very often), with items 2 and 3 reverse scored. The total score, ranging from 0 to 16, is obtained by adding the scores of all items. Higher scores indicate higher perceived stress.	12 months
Other	Depression	Depression will be measured using the Patient Health Questionnaire-9 (PHQ-9). The PHQ-9 is a widely-utilized questionnaire that gauges the severity of depression in individuals. It consists of nine items, each corresponding to a symptom of depression. The responses are scored on a scale ranging from 0 (not at all) to 3 (nearly every day), with the total score indicating the depression level. The scale's range is 0-27, reflecting varying degrees of depression severity from mild to severe.	12 months
Other	Anxiety	Anxiety will be assessed using the Generalized Anxiety Disorder 7-item scale (GAD-7). The GAD-7 is a brief measure designed to assess the severity of generalized anxiety disorder symptoms. It includes seven items that evaluate key symptoms such as nervousness, excessive worry, and fear. Respondents rate how often they have been bothered by each symptom over the past two weeks on a scale from 0 (not at all) to 3 (nearly every day). The total score ranges from 0 to 21, with higher scores indicating more severe anxiety.	12 months
Other	Psychological flexibility	Psychological flexibility will be measured using the Acceptance and Action Questionnaire - version 2 (AAQ-2). The AAQ-2 consists of seven items scored on a 7-point Likert scale ranging from 1 (never true) to 7 (always true). The total score can range from 7 to 49, with higher scores indicating greater psychological inflexibility.	12 months
Other	Functional impairment	Functional impairment will be assessed using a 15-item verion of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS-II). The WHODAS-II is a standardized instrument for measuring health and disability across various domains of functioning. It covers six domains: cognition, mobility, self-care, getting along, life activities, and participation. Each item is rated for difficulty over the past 30 days on a 5-point scale from 0 (none) to 4 (extreme or cannot do). The scores can be summed to provide a profile of functioning and disability.	12 months
Other	Subjective wellbeing	Subjective wellbeing will be measured using the WHO-5 Well-Being Index. the WHO-5 is a concise self-report tool that measures an individual's subjective well-being. It contains five questions that assess positive mood, vitality, and general interests. The responses are scored on a scale from 0 (at no time) to 5 (all of the time), and the total score is then multiplied by 4 to give a final score ranging from 0 to 100. A score of 0 indicates very poor well-being, while 100 represents excellent well-being.	12 months
Other	Child wellbeing and functioning	Child wellbeing and functioning will be assessed using one of two versions of the Kiddy-KINDL questionnaire, depending on the child's age. For children aged 3 to 4 years, the parent version consists of 24 items that cover six subscales: physical well-being, psychological well-being, self-worth, family, friends, and functioning in everyday life (school or preschool/kindergarten). The items are scored on a 5-point Likert scale from 1 (never) to 5 (all the time), and a total score is calculated to reflect overall health-related quality of life. For children aged 4 years and above, there is a self-report version of the Kiddy-KINDL which contains 12 items. This version also uses a 5-point Likert scale for responses, and it similarly assesses various dimensions of a child's well-being.	12 months
Primary	Food insecurity	Food insecurity will be assessed using the Food Insecurity Experience Scale (FIES). The FIES was developed by the FAO, and consists of 8 questions regarding the availability of sufficient food in the past thirty days. The questions form a scale calibrated against a global reference from the 2014-2016 Gallup World Poll for comparability across countries. Responses are analyzed as a scale using Item Response Theory (IRT) models, ensuring comparability of food insecurity prevalence rates.	12 months
Secondary	Dietary diversity	Dietary diversity will be assessed using the Household Dietary Diversity Score (HDDS). The HDDS is a measure of food consumption that reflects a household's access to a variety of foods. It's based on households' self-reporting of the 12 food groups consumed in the previous 24 hours.	12 months
Secondary	Child malnutrition	Child malnutrition will be assessed using the Height-for-Age Z-score (HAZ). The HAZ is a standard statistical measurement that represents how a child's height compares to a reference population of the same age and sex. It's used to assess long-term nutritional status and can indicate chronic malnutrition or stunting. A HAZ score below -2 is considered stunted, indicating that the child is significantly shorter than the average height for their age. A score above +2 would suggest the child is taller than the average height for their age.	12 months
Secondary	Psychological distress	Psychological distress will be measured using the Kessler Psychological Distress Scale (K6). The K6 is a concise tool used to screen for psychological distress. It assesses general psychological distress through six questions that inquire about symptoms of depression and anxiety experienced in the past month. Each of the six questions is scored from 0 (none of the time) to 4 (all of the time), providing a total score range from 0 to 24. Higher scores indicate greater psychological distress.	12 months
