Summary
Understanding the transition from suicidal ideation to suicide attempts or recovery is crucial for prevention. This longitudinal study tracks psychological, behavioral, and social factors in adults with suicidal ideation to identify modifiable targets.
Area of Science:
- Psychiatry and Mental Health Research
- Epidemiology
- Longitudinal Cohort Studies
Background:
- Factors influencing the transition from suicidal ideation to suicide attempts or remission are poorly understood.
- Lack of large-scale longitudinal studies specifically recruiting individuals with suicidal ideation hinders understanding of critical transition mechanisms.
- Gains in suicide prevention are unlikely without longitudinal data on determinants of suicide attempts and ideation remission.
Purpose of the Study:
- To identify key modifiable risk and protective factors predicting transitions in suicidal ideation.
- To understand distinct trajectories of suicidal ideation severity and transitions to suicide attempts over three years.
- To inform novel, tailored therapies and improve suicide prevention program targeting.
Main Methods:
- A three-year prospective, population-based longitudinal cohort study of 842 Australian adults reporting recent suicidal ideation.
- Online assessments every six months covering psychopathology, cognition, psychological, social factors, treatment, and environmental exposures.
- Yearly ecological momentary assessments to capture short-term fluctuations in suicidal ideation and related constructs.
Main Results:
- This section is to be filled once the study is completed and results are available.
Conclusions:
- The study aims to identify potential targets for novel therapies for individuals experiencing suicidal ideation.
- Findings are expected to improve the targeting and effectiveness of suicide prevention programs.
- Even modest treatment improvements could significantly reduce suicide attempts and deaths.

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

01:15Assumptions of Survival Analysis
136
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

01:18Introduction To Survival Analysis
250
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.

01:20Actuarial Approach

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.

Elisabeth Kübler-Ross significantly advanced psychology's understanding of the process of dying with her influential book, On Death and Dying (1969). She focused on studying terminally ill individuals and outlined five stages commonly experienced when coping with death: denial, anger, bargaining, depression, and acceptance.
In denial, individuals reject the reality of their condition, often thinking, "This isn't true; I feel fine," as a way to protect themselves from...
