The goal of this feasibility randomized controlled trial is to evaluate the effectiveness and acceptability of the Lighthouse Mentalization-Based Treatment Parenting Program (Lighthouse MBT-P) as an intervention for parents at risk of maltreating their children. The study focuses on parents with a history of childhood trauma, aiming to improve parent-child relationships, reduce parenting stress, and ultimately decrease the risk of child maltreatment.
The goal of this study is to test how well the Lighthouse Mentalization-Based Treatment Parenting Program (Lighthouse MBT-P) works for parents who may be at risk of harming their children. The program aims to help parents understand and manage their own and their children's emotions better. By improving these skills, the program hopes to reduce stress in parenting and lower the chances of child abuse or neglect.
The main questions this study will answer are:
Participants in this study will:
Researchers will compare the results of parents who take part in the Lighthouse MBT-P program with those who receive standard parenting support to see which approach works better.
This study is a feasibility randomized controlled trial designed to assess the Lighthouse Mentalization-Based Treatment Parenting Program (Lighthouse MBT-P) for parents who are at risk of maltreating their children. The Lighthouse MBT-P program is specifically tailored for parents with a history of trauma and aims to enhance their mentalizing abilities-helping them better understand and reflect on their own and their children's emotions and thoughts. By improving these skills, the program intends to strengthen parent-child relationships, reduce parenting stress, and ultimately decrease the risk of child maltreatment.
Study Design:
The study is being conducted at Diego Portales University in Santiago, Chile, with a total of 60 participants who will be randomly assigned to one of two groups: the intervention group receiving the Lighthouse MBT-P program and a control group receiving standard psychoeducational support. The intervention will consist of weekly 2-hour group sessions over 12 weeks, where participants will engage in psychoeducation and reflective discussions, facilitated by trained psychologists. These sessions aim to provide parents with the tools to improve their emotional regulation, understand their children's needs better, and develop healthier parenting practices.
Study Phases:
Cultural Adaptation: The Lighthouse MBT-P program has been culturally adapted to ensure its relevance and effectiveness within the Chilean context. This phase involved consultations with local experts, community stakeholders, and pilot testing with a small group of parents to refine the intervention content and delivery methods.
Clinician Training: Therapists who will deliver the Lighthouse MBT-P program have completed a comprehensive training program, including a three-day workshop and ongoing bi-weekly supervision by an MBT specialist. This training ensures that the intervention will be delivered consistently and effectively, adhering to the principles of mentalization-based treatment.
Intervention Delivery: The intervention group will participate in the Lighthouse MBT-P sessions, focusing on enhancing parental mentalizing abilities. The content will cover topics such as emotional regulation, understanding children's behaviors, and managing stress in parenting. Sessions will be conducted online, allowing for greater accessibility for participants.
Data Collection: Data will be collected at multiple time points, including baseline, post-intervention, and follow-up, to assess the feasibility and acceptability of the program, as well as preliminary indicators of its effectiveness in reducing parenting stress and improving parent-child relationships.
Analysis and Interpretation: The data collected will be analyzed using both quantitative and qualitative methods to determine the feasibility of the program and to identify any barriers or facilitators to its implementation. The results will inform decisions about whether to proceed with a full-scale randomized controlled trial and guide any necessary adjustments to the program.
Significance:
This study addresses a critical gap in the availability of trauma-informed, attachment-based interventions for parents at risk of child maltreatment in Chile. By evaluating the feasibility of the Lighthouse MBT-P program, this research aims to provide a foundation for larger-scale interventions that could significantly impact the prevention of child maltreatment and improve the well-being of vulnerable families.

| MBT Lighthouse Parenting Program | Behavioral | Lighthouse Parenting Programme, a 12-week intervention for parents, focusing on enhancing mentalizing abilities. It includes weekly group sessions (2hrs) led by 3 trained MBT psychotherapists for 8-12 parents, and fortnightly individual parenting sessions (1hr) with a practitioner. The programme, rooted in Mentalization-Based Treatment (MBT) skills, explores parents mentalizing and their childrens mentalizing and attachment styles through a variety of interactive methods, including multimedia resources and creative activities to stimulate mentalizing. Central to the programme is the metaphor of the parent as a lighthouse, guiding their child. Training for practitioners spanned 4 days, covering MBT and Lighthouse Parenting skills, with an emphasis on experiential learning and self-reflection. Ongoing weekly group supervision will ensure the quality and fidelity of the intervention. Delivered in person at University Diego Portales. |

| Feasibility of Conducting a Full-Scale Trial: Recruitment, Retention, and Protocol Acceptability Assessed Through Semi-Structured Interviews and Attendance Records | The feasibility of conducting a future full-scale trial will be assessed through the following measures: Participant Acceptability: Assessed via semi-structured interviews to capture participants' understanding, views, and experiences, including potential barriers or facilitators. Clinician Acceptability: Evaluated through in-depth interviews with clinicians, focusing on barriers, facilitators, and perceptions of the intervention. Adherence: Monitored through attendance records, with successful adherence defined as at least 65% of participants attending 40% or more of sessions. Recruitment and Retention: Recruitment tracked by the percentage of invited participants who consent to participate, with retention determined by the attrition rate, targeting no more than 20%. | Measured continuously from the start of recruitment through the end of the intervention period (12 weeks for control group, 26 weeks for intervention group). |

| Change in Parenting Stress from Baseline to 6-Month Follow-Up Using the Parenting Stress Index-Short Form (PSI-SF) | Parenting stress will be measured using the Parenting Stress Index-Short Form (PSI-SF), a 36-item self-report questionnaire. The PSI-SF includes three subscales: Parental Distress, Parent-Child Dysfunctional Interaction, and Difficult Child, with a Total Stress Score. The minimum score is 36, and the maximum score is 180, with higher scores indicating greater stress. The primary analysis will focus on changes from baseline to the 6-month follow-up after randomization. |
