The regulation cluster will be involved in an online intervention without any intimate fitness info.

Participants in both teams should be provided endless accessibility their unique allocated articles during the 6-month study cycle, but that content are going to be available simply to members just who log on with an authorized email address and code. Following study duration, the content accessed by intervention class shall be distributed around the control party subject areas at the same time.

Learn outcome

The research results are going to be determined in both communities at baseline (T0) as well as a few months (T1) and six months (T2) after standard. The primary consequence is the regularity of condomless anal sex in the past a couple of months, in line with the suggestion of a systematic post on 56 reports [42]. The second outcomes are definitely the volume of group intercourse and chemsex, self-efficacy and perceptions toward condom incorporate, and regularity of HIV alongside STI testing.

Facts on these outcome would be collected and evaluated the following.

Volume of condomless rectal intercourse in past times three months was calculated by a self-reported items at baseline, 3-month follow-up and 6-month follow-up.

Frequency of class gender previously 3 months is calculated by a self-reported items at standard, 3-month follow-up and 6-month follow-up.

Frequency of chemsex previously three months are calculated by a self-reported object at standard, 3-month follow-up and 6-month followup.

Self-efficacy in condom use are measured by validated traditional Chinese form of the Condom Self-Efficacy Scale at baseline, 3-month follow-up and 6-month follow-up [43].

Thinking towards condom use was sized of the UCLA Multidimensional Condom Attitudes size at standard, 3-month follow-up and 6-month follow-up [44].

Volume of HIV evaluating before 3 months are measured by a self-reported object at baseline, 3-month follow-up and 6-month followup.

Regularity of STI testing in earlier times 3 months is calculated by a self-reported item at baseline, 3-month follow-up and 6-month follow-up.

Ultimately, players’ sociodemographic characteristics (example. get older and knowledge degree), intimate histories (e.g. ages of sexual initiation), reported usage of pre-exposure prophylaxis and their activities of matchmaking app practices are going to be gathered.

At 6-month follow-up (T2), individuals will likely be asked if they select the internet ideas of use and therefore are satisfied with the online records.

Facts review

The steady outcome for the intervention and controls groups on 3- and 6-month follow-ups will likely be evaluated using an impartial t-test, following in comparison utilizing a linear mixed-effects design utilizing the intervention class once the covariate. Matter as random effects are going to be contained in the model if considerable. In the event of set up a baseline instability, additional investigations is going to be carried out, with modification of this variables discovered to be imbalanced. The intention-to-treat concept should be used, as well as study subjects are part of the analysis as randomised. The baseline-observation-carried-forward approach should be utilized for lost principles during the 3- and 6-month follow-ups. Product adequacy should be validated by examining the standardised residuals for normality and continual variance.


The study is big. Given the popularity of matchmaking app usage, as well as its associated intimate risks, interventions promoting secure intercourse procedures among matchmaking application consumers become urgently necessary. Besides, HIV problems can be alarming in Hong Kong. HIV circumstances in Hong-Kong hit the record extreme lately, with additional men contaminated. The amount of brand-new HIV covers improved from 513 in 2012 to 725 in 2015 and 681 in 2017. Homosexual communications could be the major route of indication. In 2017, more than 60percent caught the HIV through intercourse between males, in contrast to an average of 40percent from 1984 to 2015. These local facts delineate that HIV problems as a result of intercourse between males is the reason almost all of acquired HIV diagnoses in Hong-Kong.

a books review and meta-analysis claim that peer involvement in internet intimate fitness interventions gets better insights, attitudes and, to some degree, safe gender behaviours [45]. Towards the good our expertise, this can be initial interactive internet intervention to particularly desired MSM matchmaking app consumers. Unlike most health treatments, that are created solely by healthcare service providers, the recommended intervention shall be manufactured by both medical providers and learn members (dating app customers) utilizing a participatory design means. The acceptability and feasibility with this client-oriented intervention tend to be therefore assured. Fundamentally, the intervention is expected to boost the sexual wellness of MSM. Ultimately, although great effort currently expended internationally to stop HIV and STIs among MSM, this people remains disproportionately impacted by both. The proposed intervention will donate to global HIV and STI prevention ways.
