Summary
This study found that an online intervention for problem gambling did not significantly improve outcomes compared to no intervention. Further research with larger samples is recommended.
Area of Science:
- Behavioral Psychology
- Digital Health Interventions
- Addiction Research
Background:
- Problem gambling is a significant public health concern.
- Online interventions offer a scalable approach to address gambling behaviors.
- Previous research on online interventions for problem gambling shows mixed results.
Purpose of the Study:
- To evaluate the efficacy of an online intervention for problem gambling.
- To compare outcomes of an online intervention against a no-intervention control group.
- To assess the feasibility of recruiting participants via crowdsourcing platforms.
Main Methods:
- A pilot randomized controlled trial was conducted.
- Participants were recruited through a crowdsourcing platform (Mechanical Turk).
- Eligible participants were randomized to an online intervention or a control group, with 6-week and 6-month follow-ups.
Main Results:
- A total of 321 participants were recruited with high follow-up rates (87-88%).
- Reductions in gambling were observed from baseline across both groups.
- No significant difference in gambling outcomes was found between the intervention and control groups.
Conclusions:
- The online intervention did not demonstrate a significant impact on problem gambling outcomes in this pilot study.
- Replication with larger sample sizes is warranted.
- Future studies should consider alternative recruitment strategies beyond crowdsourcing platforms.

01:21Pilot and Numeric Relaying
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:

01:03Nursing Interventions I: Taxonomy of Nursing Interventions
3.6K
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

10.2K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

4.7K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

01:12Trial and Error and Algorithm
403
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

3.1K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:
