• Conditions: Mental Health Help-seeking

• Lead Sponsor: The Hong Kong Polytechnic University

Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Subjective norms toward mental health help-seeking	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	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.

Secondary Outcome Measures

Name	Time	Method
Perceived behavioural control	Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2)	Perceived behavioural control will be measured on a 3-item subscale of the C-TPB. Responses are rated on a 6-point Likert scale, with higher scores indicating higher levels of behavioural control.
Help-seeking attitude	Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2)	Help-seeking attitude will be measured on a 5-item subscale of C-TPB, items will be measured on a 6-point semantic differential scale, with higher scores indicating a more positive attitude towards help-seeking.
Perceived barriers to help-seeking	Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2)	Perceived barriers to help-seeking will be measured by a 6-item scale adapted from the Chinese American Psychiatric Epidemiological study (CAPES), responses are rated on a 6-point Likert scale, with higher scores indicating more significant perceived barriers to help-seeking.
Depressive symptoms	Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2)	Depressive symptoms will be measured with the Patient Health Questionnaire (PHQ-9). It is a 9-item instrument that incorporates depression diagnostic criteria with other leading major depressive symptoms and rates the frequency of the symptoms, factoring into the scoring severity index. PHQ-9 scores of 5-9, 10-14, 15-19, 20 and above represent mild, moderate, moderately severe, and severe depression, respectively.
Anxiety symptoms	Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2)	Anxiety will be measured with the Generalised Anxiety Disorder 7-item scale (GAD-7). It is a 7-item scale; responses to each item are rated on a 4-point Likert scale and range from 0 to 3. It taps on the most prominent diagnostic features for GAD, and scores of 5, 10, and 15 are taken as the cut-off points for mild, moderate, and severe anxiety, respectively.
Loneliness	Baseline (T0), post-intervention (T1, two weeks after T0), and to 12 weeks after the baseline (T2)	Loneliness will be measured with the UCLA Loneliness Scale (UCLA-3). It is a 3-item scale measuring an individual's perceived loneliness. Each item is evaluated with scores ranging from 0 (never) to 3 (often), the total score is the sum of all items, and a higher score indicates a higher level of perceived loneliness.
