Summary

This is a randomized controlled trial (RCT) to test the effectiveness of nonviolent communication (NVC) intervention for reducing parenting stress to parents with children in primary schools and mild to moderate depression. A pilot RCT on 50 participants (25 in NVC vs. 25 in control group, 2 small groups for each arm) will be conducted in late June to September 2022 to test the procedure and preliminary results. A RCT (1:1 allocation ratio) on 200 parents who have children of Grade 1-6 and mild to moderate depressive symptoms assessed by Patient Health Questionnaire (PHQ)-9. Outcomes will be measured at baseline, immediately after completion of intervention and three months after the intervention. This study will provide evidence on the effectiveness of NVC to reduce parenting stress and enhance parents' mental well-being.

Detailed description

Objectives: To test the effectiveness of nonviolent communication (NVC) intervention for reducing parenting stress in parents with mild to moderate depression and children in primary schools. Hypothesis: Our intervention group will show more improvements in parents' NVC skills, parenting stress, depression and anxiety symptoms, and well-being than the control group. Design and subjects: An RCT (1:1 allocation ratio) on 200 parents who have mild to moderate depressive symptoms assessed by Patient Health Questionnaire (PHQ)-9 and children of Grade 1-6. Instruments: Parental Stress Scale; self-developed NVC scale; PHQ-9; Generalized Anxiety Disorder-7; Short Warwick-Edinburgh Mental Well-being Scale. Interventions: Six 1.5-hour weekly online group sessions (10-14 participants in each group) will be delivered by NVC professionals to the intervention group, including (1) introduction to four key principles of NVC, communication that blocks compassion, and distinguishing observations from evaluations, (2) identifying and expressing feelings, providing a list of words to express feelings and four steps to express anger, (3) taking responsibility for feelings (needs), distinguishing between an outside event and the met or unmet needs behind the feelings, (4) using positive action language to make requests, (5) review and summary, and (6) experience sharing and suggestions for further practice. Group discussion will be used to sustain the participants' engagement. The waitlist control group will receive simple messages through the same media on physical activity and will be provided with the training sessions afterwards. A pilot study on 50 participants (25 in NVC vs. 25 in control group, 2 small groups for each arm) will be conducted in late June to September 2022 to test the procedure and preliminary results. Only T1 and T2 will be conducted to obtain the immediate effect of the intervention. Outcome measures: Outcomes will be measured at baseline, immediately after completion of intervention and three months after the intervention. The primary outcome is parenting stress at 3-month after the intervention. Secondary outcomes include NVC skills, parental depression and anxiety symptoms, and well-being at 3-month after the intervention. Process evaluation will be conducted after the intervention. In-depth interviews will be conducted on 30 parents in the intervention group to explore participants' experiences. Data analysis: Intention-to-treat approach. A multilevel mixed model will be used to evaluate the between-group mean differences in the outcomes of the two groups, after adjusting for baseline outcomes and demographics. Per-protocol sensitivity analyses will be conducted by only including the adherent participants who complete at least four sessions and all assessments. Mediation analysis will be conducted following AGReMA guideline. Cost analysis will be conducted. Expected results: The intervention group will show greater improvements in the measured outcomes than the control group, offering strong evidence of effectiveness.

Interventions

Type	Name	Description
BEHAVIORAL	Online group nonviolent communication (NVC) interventions	The primary purpose of NVC as defined by Dr. Marshall Rosenberg is to resolve interpersonal conflict using empathic communication skills. Nonviolence does not refer to the mere absence of physical harm. It is a way of life that helps us to transform old patterns of defensiveness and aggressiveness into compassion and empathy and to improve the quality of all types of relationships. The basic model of NVC consists of four key principles: the separation of observation from evaluation (observation), exploring and expressing the feelings that emerge from observations (feeling), taking responsibility for one's feelings (need), and telling others the need to enrich lives (request). A book on NVC specifically targets parents to improve communication and connection with their children. The NVC model emphasizes the importance of observation and has similarities with the concept of "mindful parenting", which refers to a non-judgmental and open parenting style.
OTHER	Waitlist control group	Waitlist control, but included a short active intervention during the 2nd and 3rd assessments.
