Summary
Suicide deaths cluster into distinct groups based on demographics and clinical factors. Identifying these suicide subgroups can improve targeted prevention strategies.
Area of Science:
- Epidemiology
- Psychiatry
- Public Health
Background:
- Suicide is a complex public health issue.
- Understanding suicide heterogeneity is crucial for prevention.
Purpose of the Study:
- To identify distinct subgroups of suicide deaths.
- To analyze demographic, clinical, and psychosocial factors associated with suicide clusters.
Main Methods:
- Coroner's chart review of 2886 suicide deaths in Toronto (1998-2010).
- Cluster analysis using known suicide risk factors.
- Comparison of clusters based on person- and suicide-specific factors.
Main Results:
- Five distinct suicide clusters were identified.
- Clusters varied by gender, method, stressors, marital status, mental illness, and prior attempts.
- Examples include clusters with high female proportion, recent stressors, young age, or no prior attempts.
Conclusions:
- Suicide deaths exhibit varied patterns in characteristics.
- Subgroup identification aids understanding of suicide's heterogeneous nature.
- Findings can inform targeted suicide prevention strategies.

8.9K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

11.0K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.

01:21Cancer Survival Analysis
863
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

01:20Cluster Sampling Method
11.0K
Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...

02:16Surveys
14.3K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
