简要总结
The present study aims to examine the effectiveness of descriptive social norm nudges and pictorial social norm nudges in improving mental health help-seeking intention compared to educational information.
详细描述
This study is a three-arm randomised controlled trial (RCT) in 540 older adults aged 60 years and above recruited through NGOs, testing the utility of revised TPB with baseline data, and the effectiveness of descriptive social norm-nudges (intervention group 1) and pictorial social norm- nudges (intervention group 2) comparing to traditional mental health education (control). Participants will be evenly randomised and receive 1 message/picture per day consecutively for 2 weeks. Researchers blind to group allocation will interview participants at baseline (T0), 2 weeks (post-intervention, T1), and 12 weeks (follow-up, T2). The primary outcomes are changes in subjective norms and help-seeking intention assessed using a revised Chinese version of the theory of planned behaviour questionnaire (C-TPB); secondary outcomes include perceived behavioural control, help-seeking attitude, perceived barriers to help-seeking (C-TPB subscales), and mental health assessed by PHQ-9, GAD-7 and UCLA-3.

结局指标
主要结局
Subjective norms toward mental health help-seeking
时间窗: Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2)
Subjective norms toward mental health help-seeking will be measured by six items adapted from the validated Chinese version of the TPB questionnaire (C-TPB) . The three items will measure descriptive norms describing what society, in general, does when facing mental health challenges, and the other three items will measure social norms describing what the significant others of the participant would do. Responses will be rated on a 6-point Likert scale, with higher scores indicating higher levels of subjective norms about mental health help-seeking.
Mental health help-seeking intention
时间窗: Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2)
Mental health help-seeking intention will be measured on a 3-item subscale of C-TPB. Responses will be rated on a 6-point Likert scale, with higher scores indicating higher levels of help-seeking intention.
次要结局
- Perceived behavioural control(Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2))
- Help-seeking attitude(Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2))
- Perceived barriers to help-seeking(Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2))
- Depressive symptoms(Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2))
- Anxiety symptoms(Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2))
- Loneliness(Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2))
