Summary
An online intervention combining cannabis use feedback with negative affect management strategies (PFI-NAC) helped reduce cannabis use in undergraduates with moderate to high social anxiety. This approach shows promise for individuals struggling to quit cannabis due to emotional distress.
Area of Science:
- Psychology
- Public Health
- Addiction Medicine
Background:
- Cannabis is the most frequently used illicit substance, with many users experiencing difficulties in cessation attempts, particularly under stress.
- Elevated social anxiety is linked to greater cannabis-related impairment, and negative affect exacerbates challenges during quit attempts.
- Most individuals with cannabis use problems desire to quit but do not seek traditional in-person treatment, highlighting the need for accessible alternatives.
Purpose of the Study:
- To evaluate the effectiveness of a novel online personalized feedback intervention (PFI) integrating cannabis feedback with negative affect management strategies (PFI-NAC).
- To determine if PFI-NAC can reduce cannabis use among undergraduate students, particularly those with social anxiety.
- To explore the interaction between social anxiety levels and the intervention's impact on cannabis use frequency.
Main Methods:
- Undergraduate students with weekly cannabis use were recruited and randomly assigned to either a one-session PFI-NAC or an assessment-only control group.
- A 2-week follow-up assessment was conducted to measure changes in cannabis use frequency.
- Statistical analyses controlled for baseline negative affect and cannabis use, examining the interaction between social anxiety and treatment condition.
Main Results:
- A significant interaction was found between social anxiety levels and the intervention condition.
- Participants with moderate to high social anxiety in the PFI-NAC group reported significantly lower cannabis use at follow-up compared to controls.
- No significant difference in cannabis use was observed between conditions for individuals with lower social anxiety.
Conclusions:
- A single-session online intervention (PFI-NAC) integrating cannabis feedback and negative affect management skills shows potential benefits for specific cannabis users.
- The intervention appears particularly effective for undergraduate cannabis users experiencing moderate to high levels of social anxiety.
- Further research with larger, diverse samples and longer follow-up periods is warranted to confirm these pilot findings.

Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires maintaining an internal dynamic equilibrium:

Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

485
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

01:24Role of Affect in Interpersonal Attraction

Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.
