Summary
Impulsiveness is linked to suicide attempts, but new research suggests attempters may not have higher trait impulsiveness than ideators. However, impulsiveness may increase in negative emotional states for attempters.
Area of Science:
- Psychology
- Psychiatry
- Behavioral Science
Background:
- Impulsiveness is a long-cited factor in suicide attempts.
- Previous research often treated impulsiveness as a single trait and lacked experimental groups.
Purpose of the Study:
- To investigate multiple dimensions of impulsiveness in suicide ideators versus attempters.
- To address limitations of prior studies by using comparative groups and multidimensional impulsiveness measures.
Main Methods:
- Study 1 compared inpatient suicide attempters, ideators, and controls on impulsiveness using self-report and behavioral measures.
- Study 2 compared similar groups based on lifetime and past-year suicidal behaviors using measures from Study 1.
Main Results:
- Study 1 indicated elevated negative urgency in attempters compared to ideators.
- Study 2 found no significant differences in any impulsiveness constructs, including negative urgency, between groups.
Conclusions:
- Suicide attempters may not exhibit significantly higher trait impulsiveness than ideators.
- Attempters might display increased impulsiveness specifically when experiencing negative emotional states.

21.7K
According to Newton’s second law of motion, the rate of change of the momentum of an object is the net external force acting on it. The total change in momentum between two timepoints thus depends on both the external force acting on it and the time over which it acts. Describing this mathematically, the total change of an object’s motion is proportional to the force vector and the time over which it is applied. This product is called impulse.

The impulse response is the system's reaction to an input impulse. In an RC circuit, the voltage source is the input, and the capacitor's voltage is the output. The system's state and output response before and after input excitation are distinctly defined.
Kirchhoff's law forms an input signal equation, with the capacitor's current and voltage providing the output. Substituting the current and dividing by RC yields a differential equation. The output for an impulse input is the impulse...

When one considers a rigid body undergoing a plane motion, which is essentially a blend of translational and rotational movement, the application of Newton's second law gives the formula for the translational movement of such a body. If this equation is multiplied by a time interval, dt, and then integrated over the limits of integration, it results in an equation that embodies the principle of linear impulse.

The total change in the motion of an object is proportional to the total force vector acting on it and the time over which it acts. This product is called impulse, a vector quantity with the same direction as the total force acting on the object.
By writing Newton's second law of motion in terms of the momentum of an object and the external force acting on it, and simultaneously using the definition of the impulse vector, it can be shown that the total impulse on an object is equal to its...

Consider a ball of mass m, attached to a massless rod of known length, subjected to a time-dependent torque. If the initial velocity of the mass is known, then the final velocity of the mass for time t can be determined using the principle of angular impulse and momentum.
Initially, a free-body diagram of the system is drawn to illustrate all the forces acting upon the system, providing a crucial understanding of the dynamics at play. Then, the principle of angular impulse and momentum is...

The angular impulse and momentum principle provides insights into how forces applied at a distance from an object's rotational axis influence its angular velocity. It builds upon the crucial relationship between the moment of force and angular momentum. By integrating this equation, substituting the limits for the initial and final times, a comprehensive expression representing the angular impulse and momentum principle is derived.
