Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

574
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

CNS Depressants: Alcohol and Nicotine

1.7K
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Dosage Regimen: Individualization

373
Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

Determination of Expected Frequency01:08

Determination of Expected Frequency

2.8K
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...

Therapeutic Drug Monitoring: Affecting Factors01:29

Therapeutic Drug Monitoring: Affecting Factors

384
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Hypothesis Test for Test of Independence01:16

Hypothesis Test for Test of Independence

8.4K
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...

Area of Science:

  • Psychology
  • Behavioral Science
  • Addiction Research

Background:

  • Emotion dysregulation is linked to alcohol consumption.
  • Affect variability, or daily fluctuation in emotions, is a key aspect of emotion dysregulation.
  • Previous research often relies on traditional self-reports, potentially lacking objectivity in measuring affect variability.

Purpose of the Study:

  • To investigate the relationship between within-person variability in negative and positive affect and alcohol consumption.
  • To examine if affect variability predicts context-specific drinking (solitary vs. social).
  • To control for mean affect levels when assessing the impact of affect variability on alcohol consumption.

Main Methods:

  • A community sample of 47 moderate-to-heavy drinkers participated.
  • Participants used handheld electronic devices to report affect and alcohol consumption thrice daily for 30 days.
  • Within-person affect variability was quantified using daily standard deviations of positive and negative affect.

Main Results:

  • Higher within-person negative and positive affect variability were associated with increased solitary and social drinking.
  • Between-person analysis showed affect variabilities related to greater social consumption.
  • Aggregated negative affect variability was linked to less solitary consumption.

Conclusions:

  • Affect variability is a significant predictor of alcohol consumption, independent of average affect levels.
  • The social context of drinking and the type of affect variability (within- vs. between-person) are crucial distinctions.
  • Findings support the notion that both negative and positive affect variabilities are detrimental, reflecting difficulties in emotional regulation.
