Abstract Background: Although comprehensive knowledge of suicide risk assessment is fundamental, training
programs for such an essential skill often include passive and didactic methods that may not facilitate recall.
Objectives: To examine the efficacy of a recently published novel visual metaphor (VM) for teaching suicide risk
factors as an adjunct to traditional teaching methods in a group of novice learners. Methods: A pilot non-blinded
randomized controlled trial (RCT) was conducted. 22 first-year undergraduate psychology students were randomly
assigned to either a control group, where they received traditional teaching (TT) or an intervention group, where they
received traditional teaching and the visual metaphor (TT+VM). Participants then completed post-learning
assessment including immediate free recall of suicide risk factors and knowledge application based on a clinical
vignette. Cognitive load and participants’ satisfaction were also assessed. Descriptive statistics and the Mann-
Whitney U test were used to analyse the data. Results: The TT+VM group demonstrated significantly better
immediate free recall of suicide risk factors (mean= 14.56, SD= 3.2, p=.026), and superior application in the clinical
vignette (mean= 14.33, SD= 1.00, p= .036). Furthermore, the TT+VM group also reported significantly less
cognitive loading while learning suicide risk factors (mean= 3.44, SD= .88, p=.001) and significantly higher
satisfaction levels (mean= 26.44, SD= 3.6, p=.001). The differences between the two groups on these domains
ranged between medium and large effect sizes. Conclusions: Preliminary findings show that the use of TT+VM
enhanced the learning of suicide risk factors. The VM could be a useful learning tool for novice learners but future
large-scale studies are warranted to replicate this positive preliminary effect.

1. Introduction
There are gaps in suicide risk assessment training [1,2,3]
and recently published work has suggested visual
metaphor (VM) as a potential way of addressing these
gaps [4]. For example, several studies have shown that
only half of psychological trainees [5,6] and community
nurses [7] received adequate risk assessment training.
Similarly, a recent study indicates that 88% of surveyed
health professionals reported having received no official
training in suicide risk assessment or management [8].
Moreover, in non-mental health nurses dealing with
high-risk groups such as oncology patients, only 1.1 %
had very good knowledge about suicide and suicide
assessment skills [9].
Available training programs rely heavily on didactic
teaching methods which might not be the most effective
way of converting knowledge about suicide risk factors
into an applied clinical skill [3]. A review of the effects of
didactic programs and interactive education on improving
clinical practice concluded that didactic programs
exhibited no-to-low effects; whereas, interactive programs
demonstrated moderate-to-high effects [10]. VM has been
proposed to help learn suicide risk factors (‘the what’),
rather than how to conduct comprehensive suicide risk
assessment (‘the how’) [4]. VM is proposed as a means to
reduce cognitive load and optimize working memory
(WM) utilization, which in turn will enhance long-term
memory processing [11,12].
The purpose of this study was to assess the efficacy of
VM as an adjunct to traditional methods in teaching
suicide risk factors to first-year undergraduate psychology
