Student summary
Why This Research Matters
Parents of children with special health care needs often experience heavy psychological distress, and nurses frequently meet these families in practice. This study is a completed randomized controlled trial, meaning it reports real results, that tested whether a brief form of psychological therapy delivered by video call could reduce parents' stress and improve their mental health. The therapy was Focused Acceptance and Commitment Therapy, often shortened to ACT, which helps people accept difficult thoughts and feelings while taking actions that fit their personal values. A key idea in this trial was task-shifting, meaning the therapy was delivered not by specialist therapists but by trained paraprofessionals, that is, non-specialist helpers who received training. The researchers wanted to know whether this more affordable and scalable approach could still work. The trial was assessor-blinded, multicentre, and used repeated measures, and it took place at six non-governmental organisation centres in Hong Kong. A total of 254 parents took part. Their average age was 39.0 years, the average age of their children was 6.0 years, and about 92.9 percent of participants were mothers. Parents were randomly assigned in a one-to-one ratio to one of two groups. Both groups received standard parenting advice, which was the usual care and consisted of six weekly e-learning modules on positive parenting plus a video review session at week six. The intervention group also received an extra 4 to 6 weekly sessions of Focused ACT, each lasting 45 to 60 minutes, delivered individually by trained paraprofessionals over video. The main outcome the researchers measured was parenting stress, using the Parental Stress Scale. They also measured depressive symptoms, anxiety symptoms, and psychological flexibility, which is the ability to stay open and adaptable while pursuing what matters. Outcomes were assessed three times: at the start (baseline), right after the program at six weeks, and again six months later. The analysis followed the intention-to-treat principle, which means participants were analyzed in the groups they were assigned to, giving a more realistic and less biased picture of effect. At the six-month follow-up, the group that received Focused ACT plus standard advice had greater reductions in parenting stress than the group that received standard advice alone, with an adjusted mean difference of -4.88 and a small effect size (Cohen d of -0.30). Depressive symptoms also fell more in the ACT group (adjusted mean difference -4.35; Cohen d -0.64, a moderate effect), and anxiety symptoms dropped more as well (adjusted mean difference -4.89; Cohen d -0.87, a large effect). Psychological flexibility improved (adjusted mean difference 3.61; Cohen d 0.67, a moderate effect). In plain terms, adding the video-delivered therapy helped parents feel less stressed, less anxious, and less depressed, and helped them cope more flexibly, with the strongest effects seen for anxiety. The authors concluded that a brief, paraprofessional-led Focused ACT program delivered by video is effective and scalable, and that it supports a model where nurses coordinate paraprofessional-delivered support to bring evidence-based care into routine paediatric and community pathways. For nursing students, this points to nurses' potential role in screening families for distress, coordinating care, and connecting parents to accessible services. A few cautions are important. This trial was carried out in Hong Kong at NGO centres, so results may not transfer directly to every culture or health system. The effect on the main outcome, parenting stress, was statistically favorable but small, so expectations should be realistic. Video-based mental health care depends on reliable internet access and privacy at home, which not all families have. Finally, paraprofessionals delivered the therapy after training and within a structured program, so this does not mean untrained people should attempt therapy; supervision, training, and clear referral pathways for parents in crisis remain essential. Overall, this is encouraging evidence that accessible, scalable mental health support can help stressed caregivers.

Study Overview
Parents of children with special health care needs endure substantial psychological distress, a challenge frequently encountered in nursing practice. While nurses are ideally positioned to identify and support these families, they require access to effective, scalable interventions that can be integrated into care pathways. This study investigated a task-shifting model, testing whether a brief, videoconferencing-delivered Focused Acceptance and Commitment Therapy programme is effective when delivered by trained paraprofessionals. To determine the efficacy of a paraprofessional-led, videoconferencing-delivered Focused Acceptance and Commitment Therapy plus standard parenting advice versus standard parenting advice alone for reducing parenting stress and improving mental health outcomes among parents of children with special health care needs. Assessor-blinded, multicentre randomised controlled trial with repeated measures. The trial was conducted at six non-governmental organisation centres in Hong Kong. Eligible parents were randomised 1:1 to (i) Focused Acceptance and Commitment Therapy plus standard parenting advice or (ii) standard parenting advice alone. Standard parenting advice (usual care for both groups) comprised six weekly e-learning modules on positive parenting plus a videoconferencing review session at week 6. The intervention group additionally received 4-6 weekly, 45-60-minute individual Focused Acceptance and Commitment Therapy sessions delivered by trained paraprofessionals via videoconferencing. The primary outcome was parenting stress (Parental Stress Scale). Secondary outcomes were depressive symptoms, anxiety symptoms, and psychological flexibility. Outcomes were assessed at baseline (T0), postintervention (6 weeks post-baseline; T1), and 6 months postintervention (30 weeks post-baseline; T2). Analyses followed the intention-to-treat principle. Among 254 parents (mean [SD] age, 39.0 [6.7] years; child age, 6.0 [2.3] years; 92.9% mothers), at T2, Focused Acceptance and Commitment Therapy plus standard parenting advice reduced parenting stress more than standard parenting advice alone (adjusted means difference, [aMD]; -4.88; 95% CI, -7.15 to -2.62; Cohen d, -0.30; 95% CI, -0.57 to -0.03). Depressive symptoms (aMD, -4.35; 95% CI, -5.43 to -3.27; Cohen d, -0.64; 95% CI, -0.91 to -0.37) and anxiety symptoms (aMD, -4.89; 95% CI, -6.00 to -3.78; Cohen d, -0.87; 95% CI, -1.14 to -0.59) decreased, while psychological flexibility improved (aMD, 3.61, 95% CI, 2.36 to 4.85; Cohen d, 0.67; 95% CI, 0.39 to 0.94). A brief, paraprofessional-led Focused Acceptance and Commitment Therapy programme delivered via videoconferencing is effective and scalable for reducing parenting stress and improving caregiver mental health. These findings support a task-shifting model where nurses coordinate paraprofessional-delivered support to integrate evidence-based care into routine paediatric and community pathways.

Practice transfer
Clinical Relevance
- Nurses are well positioned to screen parents of children with special health care needs for stress, anxiety, and depression, and to connect them with accessible, evidence-based support.
- Task-shifting, where nurses coordinate trained paraprofessionals delivering structured programs, may expand access to mental health support, though it requires proper training, supervision, and referral safeguards.
- Videoconferencing delivery can improve reach for families facing travel, time, or geographic barriers, but nurses should confirm patients have private space and reliable connectivity.
- Because effects on parenting stress were small while anxiety effects were larger, nurses should set realistic expectations and continue monitoring caregiver mental health over time.
- Any remote mental health program needs a clear plan for parents in crisis or with severe symptoms, including escalation to specialist care; brief ACT is not a substitute for treatment of acute risk.
Faculty notes
Educational Relevance
This completed, assessor-blinded, multicentre RCT (N=254; NCT06262646) is a strong teaching case for appraising a well-reported trial. It tests a task-shifting model in which trained paraprofessionals, not specialists, deliver brief videoconferencing Focused ACT to parents of children with special health care needs, against standard parenting advice alone. Use it to review intention-to-treat analysis, assessor blinding, repeated measures across three time points, and the distinction between statistical significance and clinical magnitude. The results let students interpret adjusted mean differences alongside Cohen d effect sizes: a small effect on the primary outcome of parenting stress (d -0.30), moderate on depression (d -0.64) and psychological flexibility (d 0.67), and large on anxiety (d -0.87). This invites discussion of why the primary outcome showed the smallest effect while secondary outcomes were stronger, and how to weigh that. The task-shifting framing supports conversation about nursing's coordinating role, scalability, health equity, and access. Prompt students to critique generalizability from a single-region NGO setting, the absence of an active attention-matched therapy control, potential digital-access barriers, and the need for crisis referral pathways when delivering remote mental health support.
Critical appraisal
Limitations
- The trial was conducted at six NGO centres in one region (Hong Kong), so cultural and health-system differences may limit generalizability to other settings.
- The effect on the primary outcome, parenting stress, was statistically favorable but small (Cohen d -0.30), so clinical impact on that outcome may be modest.
- The comparison group received standard parenting advice rather than an active, attention-matched therapy, so part of the benefit could reflect additional contact and attention.

Frequently asked questions
Does this trial show that video-delivered therapy works?
Yes, to a degree. This completed RCT found that adding brief videoconferencing Focused ACT reduced parenting stress, anxiety, and depression and improved psychological flexibility compared with standard advice alone, with the largest effect on anxiety.
How big were the effects?
The effect on the primary outcome, parenting stress, was small (Cohen d -0.30). Effects were moderate for depression (-0.64) and psychological flexibility (0.67) and large for anxiety (-0.87).
What is task-shifting and why does it matter here?
Task-shifting means trained non-specialists deliver care that specialists might otherwise provide. It can expand access and lower cost, and this trial suggests it can be effective when the program is structured and supervised.
Who can deliver this kind of therapy?
In the trial, trained paraprofessionals delivered it within a structured program. This does not mean untrained people should provide therapy; training, supervision, and referral pathways are essential.
Could these results apply anywhere?
Not automatically. The trial was done at NGO centres in Hong Kong, so cultural context and health-system differences mean results should be applied cautiously elsewhere.
What is psychological flexibility?
It is the ability to stay open and adaptable in the face of difficult thoughts and feelings while continuing to act on personal values. It improved in the ACT group.
What role could a nurse play?
Nurses can screen caregivers for distress, coordinate paraprofessional-delivered support, and link families to accessible services within paediatric and community pathways.
Is video therapy suitable for everyone?
Not necessarily. It requires reliable internet and private space, and it is not appropriate as the sole response for parents in crisis or with severe symptoms, who need specialist care.
Why is the primary outcome effect smaller than the anxiety effect?
The abstract does not explain why, but it is a useful reminder that a program can help some symptoms more than others, and that the primary outcome should be interpreted alongside the secondary ones.
What should families in crisis do?
Brief ACT is not emergency care. Families experiencing crisis, severe distress, or safety concerns should contact local emergency or crisis services and their healthcare provider immediately.
