Surveys

17.0K
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.

Introduction to Surveying, Plane Surveying and Geodetic Surveys

1.1K
Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

Errors and Mistakes in Surveying01:19

Errors and Mistakes in Surveying

738
Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of...

Types of Surveys01:27

Types of Surveys

372
Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...

Survey Safety01:28

Survey Safety

418
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Topographic Surveying and Contours01:29

Topographic Surveying and Contours

1000
Topographic surveying is critical for documenting the Earth's surface, focusing on capturing elevations, slopes, and natural and man-made features. It is essential in construction planning, water resource management, and land-use analysis. The primary outcome of such surveys is a topographic map, which uses contour lines to visually represent the shape and slope of the terrain, providing valuable insights into the landscape's characteristics.Contour lines are fundamental to understanding the...

Area of Science:

  • Psychology
  • Sociology
  • Public Health

Background:

  • Transgender individuals experience disproportionately high rates of mental health challenges.
  • Understanding risk and protective factors is essential for developing targeted interventions.

Purpose of the Study:

  • To investigate associations between known risk/protective factors and suicidality in Swedish transgender individuals.
  • To identify specific factors contributing to suicide ideation and attempts within this population.

Main Methods:

  • Anonymous web-based survey conducted in 2014 with 796 transgender participants (ages 15-94) in Sweden.
  • Univariable and multivariable logistic regression analyses were used to assess contributing factors.

Main Results:

  • 37% reported suicide ideation in the past 12 months; 32% had a lifetime suicide attempt.
  • Offensive treatment and trans-related violence were significantly associated with suicidality.
  • Lower satisfaction with social contacts and psychological well-being correlated with suicide ideation; lack of practical support linked to lifetime attempts.

Conclusions:

  • Suicidality among transgender individuals is directly correlated with trans-related victimization.
  • Preventing targeted victimization is a key intervention strategy to reduce elevated suicidality in the transgender population.
