Surveys

17.1K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Drug Concentrations: Measurements

1.2K
Drug concentration is the quantity of a drug present in a biological sample. Measuring drug amounts in biological samples allows the clinician to understand how a drug is absorbed, distributed, metabolized, and excreted. Samples can be obtained through invasive or non-invasive methods. Invasive techniques involve surgical or parenteral interventions to gather blood, cerebrospinal fluid, or tissue biopsy. Conversely, non-invasive approaches provide samples like urine, feces, and saliva.

Drug Concentration Versus Time Correlation

2.4K
The plasma drug concentration-time curve is a crucial tool in pharmacokinetics, representing the drug's concentration in plasma at different time intervals post-administration. This curve illustrates the drug's journey from absorption into the systemic circulation, distribution to body tissues, and eventual elimination through excretion or biotransformation.
Two pivotal parameters are the minimum effective concentration (MEC) and the minimum toxic concentration (MTC). The MEC is the...

Data Collection by Survey

9.3K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

Dose-Response Relationship: Potency and Efficacy

6.8K
The potency of a drug is the measure of its ability to produce a biological response and can be compared by looking at the half-maximum effective concentration or EC50 values of different drugs. A lower EC50 value indicates higher potency of the drug. In the dose–response curve of two antihypertensive drugs, candesartan and irbesartan, a significant difference is observed in their EC50 values. A lower EC50 value for candesartan indicates that it is more potent than irbesartan, as it...

Convenience Sampling Method00:55

Convenience Sampling Method

11.8K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

Area of Science:

  • Cannabis research
  • Substance use studies
  • Public health

Background:

  • Marijuana concentrate use is increasing, necessitating characterization of its users and usage patterns.
  • Understanding the perceived risks and predictors of frequent use is crucial for public health initiatives.

Purpose of the Study:

  • To characterize marijuana concentrate users, including demographics, reasons for use, and patterns of consumption.
  • To identify factors associated with daily or near-daily marijuana concentrate use.
  • To explore the perceived risks associated with marijuana concentrate versus flower cannabis use.

Main Methods:

  • An anonymous, web-based survey was administered to 673 US-based cannabis users recruited from Bluelight.org.
  • Data collected included marijuana concentrate use, other substance use, socio-demographics, and perceived risks.
  • Multivariable logistic regression analyses identified predictors of lifetime and daily marijuana concentrate use.

Main Results:

  • Approximately 66% of respondents reported marijuana concentrate use, with the sample predominantly male (76%) and white (87%).
  • Factors associated with increased odds of marijuana concentrate use included male gender, younger age, use of other drugs, daily herbal cannabis use, lower perceived cannabis risk, and residing in states with liberal marijuana policies.
  • Daily/near-daily concentrate use was predicted by male gender, therapeutic use, vape pen administration, and lower perceived risk of concentrate use.

Conclusions:

  • Marijuana concentrate use is prevalent among males, younger individuals, and those in states with liberal cannabis policies.
  • Daily users often employ concentrates for therapeutic reasons and utilize vaporization devices, suggesting these aspects warrant further investigation.
  • Future research should focus on community-recruited samples to further elucidate the characteristics and patterns of daily marijuana concentrate users.
