Psychological and Sociocultural Causes of Schizophrenia

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Depressive Disorders: Etiology

Depressive Disorders: Etiology

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Longitudinal Research

Longitudinal Research

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...

Theoretical Approaches to Psychological Disorder

Theoretical Approaches to Psychological Disorder

The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Borderline Personality Disorder

Borderline Personality Disorder

Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

Self-Evaluation Maintenance Model

Self-Evaluation Maintenance Model

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Summary

This summary is machine-generated.

Entrapment and past suicide attempts significantly predict repeat suicidal behavior. Targeting these individual risk factors may reduce future suicide attempts in high-risk individuals.

Area of Science:

Psychiatry
Psychology
Public Health

Background:

Suicidal behavior is a significant public health issue.
Understanding individual risk mechanisms for suicide is limited.
New predictive models for suicidal behavior are needed.

Purpose of the Study:

To investigate the predictive utility of defeat and entrapment for repeat suicidal behavior.
To examine the role of psychological factors in predicting future suicide attempts.

Main Methods:

Seventy suicide attempters completed psychological measures during hospitalization.
A national database tracked hospital readmissions for suicide attempts over four years.
Univariate and multivariate logistic regression analyses were used.

Main Results:

24.6% of participants were readmitted for suicide attempts within four years.
Univariate analysis showed defeat, entrapment, depression, hopelessness, past attempts, and ideation predicted behavior.
Multivariate analysis identified entrapment and past attempt frequency as significant predictors.

Conclusions:

The study supports a new theoretical model for predicting suicidal behavior.
Entrapment is a key individual risk factor for repeat suicidal behavior.
Targeting entrapment in interventions may reduce future suicide attempts.
