Undercounting of suicides: Where suicide data lie hidden

|August 4, 2020
Summary
Official suicide rates often underestimate actual numbers due to inaccurate death registration and misclassification. This review highlights
Area of Science:
- Public Health
- Epidemiology
- Mortality Statistics
Background:
- Official suicide rates are widely considered underestimates.
- Inaccurate death registration and cause-of-death misclassification contribute to under-counting.
- International mortality data quality varies significantly.
Purpose of the Study:
- To review the issue of under-counting deaths and suicides.
- To identify ICD-10 categories potentially concealing suicides.
- To emphasize the need for accurate suicide reporting for prevention.
Main Methods:
- Review of international research on mortality data quality.
- Analysis of ICD-10 categories: ill-defined/unknown causes, events of undetermined intent (EUI), and accidental deaths.
- Illustration using 2017 Australian mortality statistics.
Main Results:
- World Health Organization (WHO) data from Member States are often of questionable quality and not timely.
- Significant international variations exist in reported rates of suicide, ill-defined deaths, EUIs, and accidental deaths (especially poisoning).
Conclusions:
- Accurate suicide reporting is crucial for advancing suicide prevention research and programs.
- Nations must improve the collection, publication, and analysis of data on deaths coded as ill-defined/unknown, EUI, and accidental poisoning.

01:09Censoring Survival Data
422
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...

02:16Surveys

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.

01:20Actuarial Approach
223
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.

454
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

01:29Introspection

Introspection, long upheld as a reliable route to self-knowledge, involves examining one's thoughts, emotions, and mental processes. It underpins many psychological practices, from mindfulness meditation to psychotherapy and self-help strategies. However, empirical evidence challenges the accuracy of introspection as a means of understanding oneself.Limitations of Introspective InsightSeminal work by Nisbett and Wilson demonstrated that individuals are frequently unaware of the true causes...
