Description of intervention(s) / exposure
This is an observational, cross-sectional study utilising an online survey methodology to collect quantitative data. The once-off survey will be available to participants for a 30 day period.
The study will be conducted across various emergency responder organisations in Australia, including:
• NSW Ambulance Service (NSWAS) & Tasmanian Ambulance Service
• Australasian College of Paramedicine
• Other relevant emergency service organisations willing to participate
The online survey will be accessible via a secure web-based platform (Qualtrics) over a specified data collection period. The survey will take approximately 12 minutes to complete.
The survey will be available to participants for a 30 day period.
Observations will include participant levels of depression, PTSD, anxiety, insomnia, stress, resilience, and psychological well-being. In addition, they will also be asked demographic questions such as marital status, ethnicity, age, gender and current well-being practices.

Statistical methods / analysis
Sample size was calculated using the G*Power software. It was determined that 323 paramedics would provide a good balance of precision for a nationwide survey with a 5% margin of error at a 95% confidence level. Adjusted for 70% response rate would be 462.
Data Preparation:
• Data Cleaning: Post-collection, data will be reviewed for completeness, consistency, and accuracy. Missing data patterns will be assessed, and appropriate imputation methods will be applied if necessary.
• Data Coding: Responses will be coded according to standardised coding schemes for each measurement instrument.
Descriptive Statistics:
• Summary Measures: Calculation of means, medians, standard deviations, and ranges for continuous variables; frequencies and percentages for categorical variables.
• Normality Assessment: Distribution of continuous variables will be assessed using skewness and kurtosis measures, as well as visual methods (e.g., histograms, Q-Q plots).
Inferential Statistics:
1. Comparative Analysis:
o t-Tests: One-sample and independent samples t-tests will be used to compare mean scores between emergency responders and general population norms.
o ANOVA: Analysis of variance will be conducted to compare means where applicable.
2. Correlation Analysis:
o Pearson Correlation Coefficient: To assess the strength and direction of relationships between continuous variables (e.g., resilience and stress levels).
o Spearman's Rank Correlation: Used when data do not meet parametric assumptions.
3. Regression Analysis:
o Multiple Linear Regression: To identify predictors of mental health outcomes, adjusting for potential confounders (e.g., age, gender, employment status).
o Logistic Regression: For dichotomous outcomes, assessing the odds ratios of developing specific mental health conditions based on predictor variables.

Summary
Brief summary
This study aims to quantitatively assess the prevalence of mental health conditions and positive psychological factors among emergency responders in Australian Paramedics. The findings will inform the development of targeted interventions to improve mental health support and outcomes within these critical workforce sectors.
