Summary
Suicide prevention efforts are hindered by a lack of predictive models. The integrated motivational-volitional (IMV) model explains suicidal ideation through defeat and entrapment, and its transition to behavior via volitional moderators.
Area of Science:
- Psychology
- Public Health
- Neuroscience
Background:
- Suicide is a significant global public health issue with high mortality rates.
- Despite advances, predicting suicide risk remains a persistent challenge.
- Lack of comprehensive theoretical models for suicidal ideation and behavior transition is a key limitation.
Purpose of the Study:
- To present the integrated motivational-volitional (IMV) model of suicidal behavior.
- To elucidate the factors driving suicidal ideation and the transition to suicidal acts.
- To outline the theoretical basis, empirical support, and future research for the IMV model.
Main Methods:
- Theoretical model development.
- Review of existing literature on suicide risk factors.
- Conceptualization of motivational and volitional components of suicidal behavior.
Main Results:
- The IMV model proposes that defeat and entrapment precipitate suicidal ideation.
- Volitional moderators (VMs) including access to means, capability for suicide, and impulsivity, govern the transition from ideation to action.
- The model integrates psychological, social, and individual factors influencing suicidal behavior.
Conclusions:
- The IMV model offers a framework for understanding the complex pathways to suicidal behavior.
- Identifying and addressing volitional moderators can inform suicide prevention strategies.
- Further empirical testing is crucial to validate and refine the IMV model.

01:27Secondary Motives: Power Motivation and Achievement Motivation
582
Power motivation and achievement motivation are two essential social motives identified by psychologist David McClelland. These motives influence behavior in various personal and professional contexts, shaping how individuals interact with others and pursue their goals.
Power motivation is characterized by the desire to influence, control, or have an impact on others. It is shaped by an individual's experiences, social environment, and cultural context. People with high power motivation are...

01:21Secondary Motives: Affiliation Motivation and Aggression Motivation
722
Affiliation motivation is the intrinsic desire to connect with others and belong to a social group, which plays a crucial role in forming and maintaining personal relationships. This type of motivation is essential for psychological well-being, as it provides individuals with a sense of community and support. An example of this is a student who joins a study group in order to feel a sense of connection. People with high affiliation motivation actively seek social approval, take satisfaction in...

01:25Motivational Bias
368
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...

01:20Motivational Cycle
1.2K
The motivational cycle is a key concept that explains how individuals are motivated to meet their needs. At its core, the cycle revolves around four distinct stages: need, drive, goal-directed behavior, and goal achievement. These stages respond to imbalances in the body or mind, prompting actions that restore balance.
The cycle begins with a need. This need can arise from various conditions, such as hunger, thirst, or temperature changes. For instance, when an individual feels cold, their body...

01:29Introduction to Motivation and Emotion
1.3K
Motivation is a multifaceted process that drives behavior toward fulfilling various physiological or psychological needs. This process involves initiating, guiding, and maintaining specific actions influenced by internal and external factors. For example, when someone feels hungry while watching television, hunger is a motivator, prompting the individual to get up, walk to the kitchen, and find something to eat. In this instance, hunger initiates and sustains the behavior necessary to meet the...

In population modeling, integration provides a systematic way to determine accumulated quantities from known rates of change. One such application arises in ecology, where the total weight of a fish population in a body of water is referred to as its biomass. When the rate of growth of this biomass is known as a function of time, calculus can be used to determine the total biomass at a future date.Growth Rate and Biomass FunctionLet the growth rate of the fish population be represented by a...
