Abstract

Background:

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.

Aims:

This pilot study aimed at examining the effectiveness of LiCBT in Hong Kong.

Method:

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.

Results:

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: d = 0.87; anxiety: d = 0.95). For those participants reaching the clinical level of either depression and/or anxiety at pre-treatment (n = 229, 80.4%), they reported even larger effect sizes (depression: d = 1.00; anxiety: d = 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.

Conclusions:

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.
