Summary
Polysubstance-use disorder (PSUD) is linked to higher shame, guilt, and relapse rates compared to single-substance-use disorder (SSUD). Enhancing self-efficacy is crucial for reducing relapse risk in individuals with PSUD.
Area of Science:
- Psychiatry
- Addiction Medicine
- Clinical Psychology
Background:
- Most drug abuse research focuses on single-substance-use disorder (SSUD), neglecting polysubstance-use disorder (PSUD).
- Limited research compares relapse risk, emotional factors, and personality traits between individuals with PSUD and SSUD.
Purpose of the Study:
- To investigate differences in relapse risk, shame, guilt, and self-efficacy between males with PSUD and SSUD.
- To examine the mediating role of guilt and the moderating role of self-efficacy in the relationship between shame and relapse.
Main Methods:
- A comparative study involving 402 males with PSUD and 410 males with SSUD from rehab facilities in Lahore, Pakistan.
- Utilized demographic forms, the State Shame and Guilt Scale, and the General Self-Efficacy Scale.
- Employed mediated moderation analysis to assess relationships between variables.
Main Results:
- Shame-proneness positively correlated with relapse rate; guilt-proneness mediated this association.
- Self-efficacy moderated the impact of shame-proneness on relapse.
- These effects were significantly stronger in the PSUD group, who also reported higher shame, guilt, and relapse rates, but lower self-efficacy.
Conclusions:
- Individuals with PSUD exhibit greater vulnerability to relapse due to higher shame and guilt, and lower self-efficacy.
- Interventions aimed at increasing self-efficacy are recommended for drug rehabilitation facilities to mitigate relapse risk, particularly for those with PSUD.

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

01:29Psychological 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...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.

01:15Drug Abuse and Addiction: Pharmacological Phenomena

Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...
