Web-based Single-session Growth Mindset Intervention for Allied Health Practicum Trainees to Reduce Anxiety

Anxiety related to practicum will be measured by four items, including "level of anxiety about starting the practicum", "how much your anxiety will interfere with their learning", "how prepared you are for the practicum" and "how excited you are to participate in the practicum". Each statement will be rated on a 10-point Likert scale, ranging from 1=completely not anxious, very small, completely unprepared, and completely unexcited to 10=extremely anxious, very great, perfectly prepared, and extremely excited.

Psychological states will be assessed by the Depression, Anxiety and Stress Scale-8 Items (DASS-8) is a set of three self-report scales designed to measure the psychological states of depression, anxiety and stress. Each of the depression and anxiety sub-scales of the DASS-8 contain 3 items while the stress sub-scale contains 2 items. Each item can be scored from 0 (Did not apply to me at all) to 3 (Applied to me very much, or most of the time).

Performance anxiety will be examined by the sub-scale of cognitive anxiety from the Performance Test Anxiety questionnaire (PTA). Respondents indicated how they were thinking and feeling about their practicum (using a 5-point scale on which 1=totally disagree and 5=totally agree) in response to the items.

Learning orientation will be assessed by five items (e.g., "I like to learn new knowledge in practicums."). Each item will be rated by a five-point Likert scale from 1=strongly disagree to 5=strongly agree.

Confidence will be assessed by a six-item self-developed scale. Items generated from interviews with practicum students, such as "I am confident that I can listen to comments from supervisors/colleagues/service users with an open mind." and "I am confident that I can manage my time well and cope with my practicum work and schoolwork at the same time.". Each item needs to be rated from 1=strongly disagree to 5=strongly agree.

Resilient Coping will be measured by a self-report four-item Brief Resilient Coping Scale (BRCS). Items will be scored from 1 (Does not describe me at all) to 5 (Describe me very well). A sample item is "I look for creative ways to alter difficult situations".

Stress will be examined by the Perceived Stress Scale-4 items (PSS-4). It measures the degree to which situations in one's life over the past month are appraised as stressful. Each item will be scored from 0 (Never) to 4 (Very often). Total score is determined by adding together the scores of each of the four items. Questions 2 and 3 are reverse coded.

Practicum-related concerns will be assessed using a self-developed six-item scale designed to reflect the concerns of allied health students.

Time management will be assessed using the 'Setting Goals and Priorities' sub scale of the Time Management Behavior (TMB) Scale, which includes ten items. Each item is rated on a 5-point Likert scale ranging from 1 (seldom true) to 5 (very often true).
