Evaluation of a Gatekeeper Training Program

Study Overview
=================
Brief Summary
-----------------
The main objective of the proposed study is to evaluate the efficacy of a gatekeeper training suicide intervention program, Applied Suicide Intervention Skills Training (ASIST), in improving medical students' knowledge about suicide intervention, impact of attitudes on someone at risk for suicide and competent use of intervention skills to recognize risk and intervene effectively compared to medical education as usual. This research project will be undertaken using a randomized-controlled trial design. Questionnaires and objective structured clinical examinations using simulated patients will be completed at three time points: 1) before training, 2) after training, and 3) at one year following the training. Medical students' clinical skills in recognizing risk and intervening with simulated patients, as well as knowledge about suicide intervention and the impact of attitudes on someone at risk for suicide will be evaluated.

Detailed Description
-----------------
The current proposal plans to implement and evaluate a secondary suicide intervention skills training program (gatekeeper training) in medical school students in Winnipeg, Manitoba, Canada. The main objective of the current proposal is to evaluate the effectiveness of a gatekeeper training program, Applied Suicide Intervention Skills Training (ASIST), in improving medical students' intervention skills with suicidal patients compared to training as usual. Secondary aims include comparisons of changes in knowledge, perceived competence and attitudes around suicide. Findings from previous studies have demonstrated a significant positive effect of gatekeeper training on suicide prevention attitudes, skills and knowledge. As well, general studies in medical education reveal that students who have been able to practice, observe, and receive feedback in small groups showed an improvement in skills and confidence over those who were given didactic teaching only. Therefore, the investigators anticipate that the ASIST training program will significantly improve medical students' knowledge about suicide intervention, and will increase their recognition and response to suicide risk compared to education as usual. The investigators also expect that ASIST training will help them to understand the impact of attitudes on suicide prevention, and will increase their perceived competence and ability to recognize and treat a suicidal individual compare over training as usual. It is hypothesized that medical students trained in ASIST will differ significantly in their ability to correctly recognize and intervene with suicidal individuals based on their use of a standardized suicide intervention model and objective assessment using standardized patients.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: ASIST intervention<br>The gatekeeper training intervention group received the Applied Suicide Intervention Skills Training (ASIST) 10.0 in addition to TAU. ASIST is a two-day (fourteen hour), intensive, interactive and practice-dominated course aimed at enabling people to recognize risk and learn how to intervene immediately to prevent suicide. The intervention was offered to students on a weekend and was conducted by three senior ASIST trainers and one junior trainer, with two trainers assigned to each training group. | Other: ASIST<br>* The gatekeeper training intervention group will receive the Applied Suicide Intervention Skills Training (ASIST) workshop in addition to training as usual. ASIST is a 2-day intensive, interactive and practice-dominated course aimed at enabling people to recognize risk and learn how to intervene immediately to prevent suicide.<br>|
| No Intervention: Control group: training as usual<br>Training as usual consisted of didactic teaching and a tutorial with case-based examples around suicide risk factors in their first year of medical school. Third- and fourth-year students may also have the opportunity to practice their skills with real patients during their clerkship rotations or in the emergency department. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| OSCE checklist total score | Four Objective Structured Clinical Examinations (OSCEs) stations were developed for each time point in the study. All student-patient interactions were videotaped. Raters blind to the student's group assignment rated the videos according to a checklist of desired gatekeeper behaviors based on the key components of the ASIST program. A total score was the sum of all behaviours performed. | 1 week before training, 1 week following training, and 4 years following training | 
| SIRI-2 score | The Suicide Intervention Response Inventory (SIRI-2) is a self-administered questionnaire designed to measure competence in choosing appropriate responses to a series of clinical scenarios with suicidal individuals. It contains 25 items, each of which consists of a client remark and two helper responses. Respondents were instructed to evaluate the appropriateness of each of the two helper responses on a 7-point Likert scale, ranging from +3 (highly appropriate response) through 0 (neither appropriate nor inappropriate response) to -3 (highly inappropriate response). Ratings by a group of expert suicidologists and crisis interventionists provided a mean expert response criterion against which individual respondents are compared. The sum of the absolute value of the differences between the students' rating and the mean response from experts was calculated to obtain an overall score of how well the student performed with respect to expert responses. | 1 week before training, 1 week following training, and 4 years following training | 
| OSCE global rating total score | Four Objective Structured Clinical Examinations (OSCEs) stations were developed for each time point in the study. All student-patient interactions were videotaped. Raters blind to the student's group assignment rated the videos. Raters were asked to give a global rating score according to the performance of each student in each of the 3 key areas trained by the ASIST program, and a global rating of the student's performance on the station in general. The sum of all global ratings was used to determine a total score. | 1 week before training, 1 week following training, and 4 years following training | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| self-perceived knowledge about suicide | A single question measured the level of knowledge about suicide that the individual believes they have. Response options were on a 4-point Likert scale from very to not at all. | 1 week before training, 1 week following training, and 4 years following training | 
| self-perceived skill in helping a suicidal individual | A single question measured the level of ability that the individual believes they have in helping a suicidal person. Response options were on a 4-point Likert scale from very to not at all. | 1 week before training, 1 week following training, and 4 years following training | 
| self-perceived confidence in helping a suicidal individual | A single question measured the level of confidence that the individual believes they have in helping a suicidal person. Response options were on a 4-point Likert scale from very to not at all. | 1 week before training, 1 week following training, and 4 years following training | 
| Attitudes towards suicide total score | The Attitudes Towards Suicide Questionnaire (ATTS) was used to measure attitudes toward suicide. This scale is comprised of 37 items. Each item is rated on a 5-point Likert scale ranging from Strongly Disagree (1) to Strongly Agree (5). The total score of all 37 items was used for evaluation. | 1 week before training, 1 week following training, and 4 years following training | 
| self-perceived preparedness | A single question measured the level of preparedness that the individual believes they have in dealing with a suicidal individual. Response options were on a 4-point Likert scale from very to not at all. | 1 week before training, 1 week following training, and 4 years following training | 
| Total score on Interpersonal Skills Rating Scale | Interpersonal skills as rated by standardized patients in the OSCE setting according to the Interpersonal Skills Rating Scale. The IPS Rating Scale used 13 items to evaluate communication skills in the OSCE setting between patient and student from the patient's perspective, and included concepts such as empathy, respect, sensitivity, and listening skills. Each item was scored on a 7-point Likert scale from strongly agree to strongly disagree. The sum score of all 13 items was used for analysis. | 1 week before training, 1 week following training, and 4 years following training |
