NCT05337761

Brief Summary

A cluster randomized trial will be conducted for six months. To avoid covariate imbalance at baseline, stratified permuted block randomization with a 1:1 allocation ratio will be done. At least 387 boaters across 7 clusters per arm will be interviewed post baseline to give a 90% power to detect the effect of the intervention if such effect exists. A mixed effects multi-level modeling at 5% alpha level will be done using logical model building procedures

Outcome Measures

Primary Outcomes (1)

  • Change in prevalence of lifejacket wear among the boaters

    The intention to treat analysis will be used to assess the change in prevalence of lifejacket wear among the boaters. Multilevel modeling (cluster level model and boater level model) with a focus on the individual as the unit of analysis while accounting for clustering will be conducted. The generalized estimating equation (GEE) will be used to account for within-cluster variations. The goodness of fit of the model will be tested using the Hosmer Lemeshow test. Comparison between the baseline and end-line will be done and the difference in differences (Diff in Diff) will be reported to show the change of effect in the intervention and control arm.

    Six months

Study Arms (2)

Intervention

EXPERIMENTAL

The peers will be trained to train their colleagues (fellow boaters) on proper lifejacket use. A training manual has been developed for this.

Behavioral: Peer-led training on lifejacket wear

Control

PLACEBO COMPARATOR

The Marine Police will be encouraged to continue conducting their community policing on water safety and emphasize lifejacket wear.

Behavioral: Peer-led training on lifejacket wear

Interventions

Training on proper lifejacket wear will be given to peers who will be the change agents amongst their fellow boaters

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The landing sites (clusters) should not be flooded, should not be receiving any known educational/behavior related intervention except the routine marine police messages

You may not qualify if:

  • Landing sites that are inaccessible because of the bad terrain and poor security
