Abstract
This study examines whether structured community dialogue can help rebuild trust, cooperation, and social cohesion in a context affected by violent conflict. The research focuses on residents of the town of Palma, in Cabo Delgado, Mozambique, who were displaced by the conflict and have since returned to their communities.
Participants are randomly assigned to one of three groups. One group does not take part in any dialogue activity (control group). A second group participates in a community dialogue facilitated by a respected religious leader. A third group participates in a similar dialogue facilitated by a government official. The dialogues are designed to encourage respectful discussion about everyday community life, experiences of displacement and return, mutual perceptions, and ways to coexist peacefully after violence.
The study collects survey data before and after the intervention to measure outcomes related to trust, social cohesion, perceptions of leaders and institutions, willingness to cooperate with others in the community, and attitudes toward conflict and peace. The project aims to understand whether the identity of the dialogue facilitator—religious or governmental—matters for rebuilding social ties and improving relations between citizens and local institutions in fragile and post-conflict settings.
Findings from this study will contribute to evidence on low-cost, community-based approaches to social reconstruction and peacebuilding, and may help inform policies and programs in regions affected by displacement and armed conflict.

Interventions

Intervention(s)
The intervention consists of a one-time, in-person community dialogue held with small groups of local residents. The dialogue is structured and moderated, and focuses on everyday community life, experiences related to displacement and return, and peaceful coexistence after conflict.
Participants are randomly assigned to one of two dialogue formats. In one format, the discussion is facilitated by a respected religious leader from the local area. In the other format, the discussion is facilitated by a government official. The content and structure of the dialogue are the same across formats; only the identity of the facilitator differs.
A third group of participants does not take part in any dialogue and serves as a comparison group.

Primary Outcomes

Primary Outcomes (end points)
The primary outcomes of interest measure social cohesion, trust, and attitudes toward community members, leaders, and institutions in a post-conflict setting. These outcomes are designed to capture both explicit and implicit dimensions of beliefs and preferences, as well as behavioral intentions related to cooperation and peaceful coexistence.

The main primary outcomes are:
1. Social cohesion and willingness to cooperate
- Willingness to cooperate with neighbors and other community members.
- Acceptance of shared decision-making and participation in community activities.
- Willingness to interact, work with, or accept leadership from individuals with whom respondents may have had conflicts in the past.
2. Trust
- Trust in other community members.
- Trust in religious leaders.
- Trust in government officials and public institutions.
- Trust in people associated (directly or indirectly) with the conflict.
3. Attitudes toward conflict, violence, and coexistence
- Acceptance or rejection of violence as a means to address grievances.
- Attitudes toward insurgents or former combatants, including forgiveness, punishment, or reintegration.
- Perceived prevalence of violent or “malfeitor” behavior within the community.
4. Perceptions of legitimacy and moral authority
- Perceived fairness, integrity, and appropriateness of leaders (religious or governmental) as community representatives.
- Beliefs about whether leaders act in the interest of the community or selectively favor certain groups.
5. Implicit and sensitive attitudes
- Implicit associations between authorities, insurgents, and positive or negative attributes.
- Sensitive attitudes related to violence, trust, and social norms measured through indirect elicitation methods.
6. Emotional responses to community narratives
Emotional reactions expressed during open-ended responses about the community, the state, and the conflict, measured through multiple modalities.
Primary Outcomes (explanation)
Several primary outcomes are constructed indices or latent measures that combine information from multiple survey instruments and measurement modes. These outcomes are constructed as follows:
1. Social Cohesion Index
This index aggregates standardized responses from multiple survey items capturing:
Willingness to cooperate with others in the neighborhood.
Acceptance of shared community decision-making.
Comfort interacting with individuals linked to past conflict.
Beliefs about whether community members generally cooperate or exploit one another.
Items are standardized and combined into an index using either simple averaging or inverse-covariance weighting, depending on robustness checks.
2. Trust Indices
Separate trust indices are constructed for:
Interpersonal trust (neighbors, community members).
Religious authority trust (religious leaders).
State trust (local, provincial, and national government officials).
Each index combines Likert-scale responses measuring confidence, perceived honesty, and perceived fairness of the relevant group.
3. Attitudes Toward Violence and Reintegration
This outcome combines:
Explicit survey questions on acceptance of violence.
Preferences regarding punishment versus forgiveness of insurgents.
Willingness to accept former insurgents back into the community.
To reduce social desirability bias, this outcome is complemented by indirect measures (see below).
4. Implicit Association Test (IAT) Outcome
Implicit attitudes are measured using an Implicit Association Test that captures the strength of automatic associations between:
Authorities vs. insurgents, and
Positive vs. negative emotional attributes.
The primary IAT outcome is the standardized D-score, computed using response latencies and error rates following established IAT scoring procedures. Higher values indicate stronger implicit associations favoring authorities over insurgents.
5. List Experiment and Graphical List Experiment Outcomes
Sensitive attitudes related to violence, trust, and social norms are measured using:
A standard list experiment with neutral control items and a sensitive item.
A graphical list experiment using images instead of text to reduce literacy constraints.
The primary outcome is the estimated prevalence of agreement with the sensitive item, inferred from differences in mean item counts between treatment and control lists.
6. Vignette-Based Evaluation Outcomes
Respondents evaluate fictional characters presented in vignettes that vary by role (e.g. authority figure or insurgent) and behavior. Outcomes include:
Trust in the character.
Perceived moral character and fairness.
Willingness to interact with or follow the character.
These measures capture normative judgments and moral evaluations in a controlled narrative setting.
7. Emotional Response Measures (Multimodal)
For a subset of open-ended questions, responses are captured using:
Video (facial expressions),
Audio (voice and speech patterns), and/or
Text (verbatim responses), depending on participant consent.
Primary emotional outcomes are constructed by extracting indicators of emotional valence and intensity from:
Facial emotion analysis (e.g. positive vs. negative affect),
Audio-based emotion and sentiment features,
Text-based sentiment and thematic analysis.
These measures are used to complement self-reported attitudes and capture affective responses that may not be fully expressed in survey scales.
8. Composite Primary Outcome
For some analyses, a pre-specified composite index combines standardized measures of:
Social cohesion,
Trust,
Attitudes toward violence and coexistence,
Implicit and indirect attitude measures.
This composite outcome is designed to capture overall changes in social relations and conflict-related attitudes resulting from the intervention.

Secondary Outcomes

Secondary Outcomes (end points)
In addition to the primary social cohesion / trust / conflict-attitudes endpoints, we will analyze the following secondary outcomes:
1. Economic well-being and expectations
- Current income bracket and expected income in 5 years.
- Occupational expectations for self and aspirations for children/youth in the household.
2. Perceived safety and fear
- Self-reported neighborhood and town security.
- Avoidance behavior (places the respondent fears going).
- Sleep disruption due to fear and ability to “rest mentally” at night.
3. Rumors, information environment, and perceived uncertainty
- Frequency of hearing security-related rumors.
- Behavioral responses to rumors (e.g., avoiding places due to rumors).
- Beliefs about whether rumors are usually true, and perceived ability to identify false information.

4. Community governance and dispute resolution
- Perceptions of how decisions are made in the neighborhood (leader-driven vs deliberative).
- Perceived participation of men/women/youth in decisions.
- Perceived fairness and transparency of dispute resolution.

5. Treatment experience and perceived quality of dialogue
- For participants who attended a dialogue session: perceptions of facilitator neutrality, respect, balance, and whether the dialogue increased willingness to cooperate.

Experimental Design

Experimental Design
The study uses a randomized controlled design with three groups. Eligible participants are randomly assigned at the individual level to one of the following conditions: (i) a control group that does not participate in any dialogue activity, (ii) a group invited to participate in a community dialogue facilitated by a religious leader, or (iii) a group invited to participate in a community dialogue facilitated by a government official.
Random assignment is conducted prior to the intervention. Participants in all groups are surveyed using the same instruments before and after the intervention. The comparison across groups allows the study to estimate the causal effects of participating in a community dialogue, as well as whether the type of facilitator influences outcomes.
The study is implemented in the town of Palma, Cabo Delgado, Mozambique.
