Improving Family Communication in Older Adults: A Pilot Randomized Controlled Trial (ReFrame-P)

March 19, 2026 updated by: YU Yee Man Branda, The University of Hong Kong

Pilot Evaluation of ReFrame-R: A Communication Training to Reframe Older Adults' Family Roles and Promote Active Aging

This study evaluates the effectiveness of "ReFrame-R," a communication training program designed to help older adults in Hong Kong navigate intergenerational challenges. By focusing on enhancing communication competence and clarifying role boundaries within parent-child relationships, the research seeks to determine if this specialized intervention can improve the mental well-being of both older and younger generations. The study asks whether participating in the "ReFrame-R" curriculum leads to measurable improvements in how families interact, hypothesizing that older adults in the training group will demonstrate significantly better communication quality and a stronger sense of meaning compared to those in a control group. This study also aims to evaluate the program's overall feasibility and acceptability.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: ReFrame-R training
The ReFrame-R comprises four weekly 90-minute group sessions (total 6 hours), supplemented by brief weekly individual consultations to troubleshoot barriers and reinforce home practice. Adapted from an existing MI protocol for lay people (Kline et al., 2022), the program is grounded in Family Systems Theory to address over-/underfunctioning dynamics in older parent-adult child relationships, while also emphasizing empathic listening and autonomy-supportive communication. An MI skills booklet will be distributed to support and record home practice.
Behavioral: ReFrame-R
The ReFrame-R program is adapted from an established Motivational Interviewing (MI) protocol for laypersons (Kline et al., 2022). Grounded in Family Systems Theory, the curriculum specifically addresses over-functioning and under-functioning dynamics often found in older parent-adult child dyads and the cultural specific context of Hong Kong. Unlike general communication workshops, this program emphasizes role boundaries within parent-adult child relationship.
No Intervention: Control group
Participants in the control group will not receive active training during the study period. They will be provided with the same MI skills booklet for reference and self-directed practice.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Perceived communication competence
Time Frame: Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
Participants' self-perceived communication competence is assessed using an 11-item scale adapted from the Family Communication Scale (FCS). The scale consists of 10 items adapted from the original FCS to measure perceived ability to engage in positive communication with adult children, plus an additional item regarding overall communicagtion competence. Each item is rated on a 5-point scale (1-5), with a total score ranging from 11 to 55. Higher scores indicate a higher level of perceived communication competence.
Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
Meaning in life
Time Frame: Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
The 10-item Meaning in Life Questionnaire (MLQ; Steger et al., 2006) is used. It consists of two subscales: presence of meaning (5 items) and search of meaning (5 items). Each subscale is rated on a 7-point scale, with summed scores are calculated (ranged 5-35 for each). Higher scores indicate stronger sense of purpose and motivation to find meaning, respectively.
Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Self-efficacy
Time Frame: Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
Participants' self-efficacy will be assessed using the 6-item General Self-Efficacy Scale (GSE-6; Romppel et al., 2013). It is typically rated on a 4-point scale from 1 to 4. Total scores range from 6 to 24, with higher scores reflecting greater perceived self-efficacy.
Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
Well-being
Time Frame: Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
The 5-item WHO Well-Being Index will be adopted for measuring participants' subjective well-being (Bech, 1998; Kong et al., 2016), rated on a 7-point scale. The WHO-5 score ranges from 0 to 25, zero representing worst possible mental well-being and 25 representing best possible mental well-being.
Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
Role boundaries
Time Frame: Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
We used a 5-item scale adapted from the Control subscale of the Parent-Adult Child Relationship Questionnaire's Relationship with Father component (PACQF; Peisah et al., 1999). While the original scale assess children's perceptions of parental conrtol, this adapted version is a self-report measure for parent to assess their attempt to maintain power, influence, or dominance over their adult children. Each item is rated on a 5-point scale, with a total score ranging 5-25. Higher scores indicater higher levels of parent control, reflecting weaker awareness of role boundaries in parent-adult children relationship.
Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
Family functioning
Time Frame: Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
The 5-item Family Adaption, Partnership, Growth, Affection, Resolve questionnaire (Family APGAR; Chan et al., 1988; Smilkstein, 1978) is used. This scale assesses participants' satisfaction with five aspects of family function. Each item is rated on a 3-point scale (0-2), with a total score ranged from 0 to 10. Higher scores indicate better family functioning.
Baseline, Week 4 (end of training), Week 6 (2 weeks follow-up)
Training appropriateness
Time Frame: Week 4 (end of training)
We used the 4-item Intervention Appropriateness Measure (IAM) from Weiner et al (2017) to access training appropriateness. All items are rated on a 5-point scale (1-5), with an average score being calculated. Higher scores indicate greater perceived appropriateness of training.
Week 4 (end of training)
Training acceptability
Time Frame: Week 4 (end of training)
The 4-item Acceptability of Intervention Measure (AIM) from Weiner et al (2017) is adopted to access training appropriateness. All items are rated on a 5-point scale (1-5), with an average score being calculated. Higher scores indicate greater perceived acceptability of training.
Week 4 (end of training)
Training feasibility
Time Frame: Week 6 (2 week follow-up)
This study used the 4-item Intervention Appropriateness Measure (IAM) from Weiner et al (2017) to access training feasibility. All items are rated on a 5-point scale (1-5), with an average score being calculated. Higher scores indicate greater perceived feasibility of training.
Week 6 (2 week follow-up)
