To cope with the rising demand for psychological treatment, evidence-based low-intensity cognitive behavioural therapy (LiCBT) delivered by trained para-professionals was introduced internationally.
This pilot study aimed at examining the effectiveness of LiCBT in Hong Kong.
This study was of an uncontrolled pre- and post-treatment design, testing LiCBT at a local community mental health centre in Hong Kong. Two hundred and eighty-five Chinese adult help-seekers to the centre attended two or more sessions of LiCBT delivered by trained para-professionals. These participants also rated their depression and anxiety on the Patient Health Questionnaire-9 (PHQ-9) and Generalised Anxiety Disorder Scale-7 (GAD-7), respectively, at pre- and post-treatment.
Comparison of the pre- and post-treatment PHQ-9 and GAD-7 scores of 285 participants indicated significant improvements in depression and anxiety with large effect sizes (depression: = 0.87; anxiety: = 0.95). For those participants reaching the clinical level of either depression and/or anxiety at pre-treatment ( = 229, 80.4%), they reported even larger effect sizes (depression: = 1.00; anxiety: = 1.15). The recovery rate was 55.9% with a reliable improvement rate of 63.9%. An average of 5.6 sessions was offered to the participants with each session spanning a mean of 42 minutes. The baseline clinical conditions and participants' educational level were predictive of post-treatment recovery.
The results supported the effectiveness and cost-efficiency of LiCBT for depression and anxiety at a Hong Kong community mental health centre. The effect sizes and the recovery and reliable improvement rates achieved were comparable to those reported from countries such as the UK and Australia.
为应对对心理治疗日益增长的需求，由经过培训的准专业人员提供的循证低强度认知行为疗法（LiCBT）在国际上被引入。
本试点研究旨在检验LiCBT在香港的有效性。
本研究采用非对照治疗前和治疗后设计，在香港当地一家社区心理健康中心对LiCBT进行测试。285名到该中心寻求帮助的中国成年求助者参加了由经过培训的准专业人员提供的两节或更多节LiCBT课程。这些参与者还分别在治疗前和治疗后，根据患者健康问卷-9（PHQ-9）和广泛性焦虑障碍量表-7（GAD-7）对自己的抑郁和焦虑程度进行评分。
对285名参与者治疗前和治疗后的PHQ-9和GAD-7评分进行比较，结果表明抑郁和焦虑症状有显著改善，效应量较大（抑郁：=0.87；焦虑：=0.95）。对于那些在治疗前达到抑郁和/或焦虑临床水平的参与者（=229，80.4%），他们报告的效应量更大（抑郁：=1.00；焦虑：=1.15）。康复率为55.9%，可靠改善率为63.9%。参与者平均接受了5.6节课程，每节课程平均时长为42分钟。基线临床状况和参与者的教育水平可预测治疗后的康复情况。
研究结果支持LiCBT在香港社区心理健康中心治疗抑郁和焦虑方面的有效性和成本效益。所取得的效应量以及康复率和可靠改善率与英国和澳大利亚等国家报告的结果相当。
