Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Contact&Connect is a multimedia-based package of brief contact interventions (BCIs). These will be delivered to participants as rich text messages with embedded hyperlinks to microsites, videos, electronic passbooks, and digital wallet cards that provide basic information to improve mental health literacy and encouragement to connect socially with others through the use of “reward tokens”. Participants will also be provided with an electronic passbook containing information on emergency contacts.

Although content will be developed through qualitative focus group sessions with members of the construction industry and in collaboration with our partner organisation, Incolink, to ensure the resources are appropriate and acceptable to participants, BCIs will be delivered as structured contacts that seek to provide support, education and maintain long-term contact with individuals. The intervention will largely be educational with content flowing across three main themes: de-bunking myths and stereotypes, normalisation, and empowerment.

The Contact&Connect intervention will be delivered over six weeks. Participants receive two BCIs in the first week, then receive one a week for five weeks. Monitored usage of the embedded hyperlinks will be used to monitor adherence throughout the intervention.

Eligibility
Key inclusion criteria
Construction workers who are currently unemployed and own a smart phone with enabled internet connectivity and adequate data download capacity are eligible. Those who are eligible are registered with Incolink (a social welfare trustee company that provides support to unemployed members of the construction industry). The intervention is primarily aimed at males. However, because of strong interest from females, these participants are also included and analyzed separately in sensitivity analysis.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Those excluded from the study were people not in possession of a smart phone with enabled internet connectivity with adequate data download capacity, and those with insufficient English language ability. We will analyse females as a sensitivity analyses, as we found number of them were interested in taking part in the study. We did not exclude any construction worker on the basis of age
