Observational Design

Observational design refers to a research method in which the researcher observes and records behavior without directly interfering. This approach allows for the study of natural behavior in real-world settings. Observational design is commonly used in psychology to gather data on human behavior, providing valuable insights into social interactions, developmental processes, and other aspects of human psychology.

    As the name suggests, in the use of the systematic observation method for studying clinical aspects of behavior, attempts are made to observe the target aspect of the behavior in a systematic way, along with its careful recording for deriving the needed conclusion in view of the objectives of the research study. The nature of such observation thus differs a lot from our routine observation in daily life. It is quite systematic as well as objective in its processing and outcomes. Because it entails the observation and recording of the clinical aspects of one’s behavior in its natural setting, it is termed the naturalistic observation method.
    Systematic or Naturalistic Observation Method
    The research method in which the investigator tries to observe and record the occurrence of people’s behavior in its natural setting in a systematic way for deriving the needed conclusion in view of the objectives of the research study.
    In its use and application, this observation method is regarded as one of the most convenient and appropriate methods for investigation employed in clinical psychology. We can get valuable quantitative as well as qualitative information about aspects of peoples’ clinical behavior by the systematic and careful observation of their behavioral activities going on in their natural, day-to-day living. A clinical psychologist or researcher may collect valuable data or information regarding the causation, symptoms and syndromes, characteristic features, assessment and diagnosis, and the effectiveness of preventive and treatment measures related to mental illness and disorders of individuals in various physical and social situations of real-life contexts.

    Styles and Ways of Carrying Out Observation

    The task of observation carried out in the use of the systematic or naturalistic observation method for investigation in clinical psychology may usually take one of the forms and styles known as participant and non-participant observation. Let us examine them.
    • Participant Observation:

    Computer-aided interviewing is one particular form of interview that is used for telephone surveys. Here the computer assists interviewers by telling them which question to ask next. Computer-aided interviewing also allows researchers to conduct split-ballot surveys. That is, they can help to turn surveys into experiments by introducing manipulations. The computer achieves this because it is programmed either to produce different questions depending on previous responses or to ask different people different questions (randomly assigning them to different conditions).
    Observational studies are widely used in both human and animal research and involve the observation of behaviour. Naturalistic observational studies do this without any attempt to interfere with that behaviour. As an example, comparative psychologists might study the behaviour of animals by observing them in the wild, or environmental psychologists might study the movement of people through a shopping centre or the flow of traffic through an intersection. In all of these cases there is no attempt to change behaviour through intervention (e.g., in the form of an experimental manipulation).
    Observational studies can take many forms. One possibility is direct public observation, where the participants are fully aware that they are being observed. This is normally true in case studies (as discussed in Chapter 3 ). For example, organizational psychologists might want to know how corporate boardrooms really work. Suppose they want to examine the hypothesis that male board members have more power than female members. The psychologists might obtain permission to attend a company’s boardroom meetings for a few months in order to get a picture of what is going on. While attending meetings they would attempt to measure the amount of control over decisions that was exerted by males and females. To do this they might record the amount of time male and female board members spent talking during meetings, the number of times their suggestions were agreed to by other members, or the number of times males and females were interrupted. However, if the board members know they are participating in research, their behaviour might clearly change. For example, men may want to appear more reasonable and so restrain from engaging in dominant behaviour. Here, then, observation raises the possibility of reactivity that we discussed in the previous chapter. This is one reason why researchers will often try to conduct non-obtrusive observational studies,

  • Kasper, Garber, and Walsdorf (2007) studied young women's knowledge of and beliefs about osteoporosis. Kasper et al. used a predeveloped survey, The Multiple Osteoporosis Prevention Survey, to determine college-age women's knowledge of and beliefs about osteoporosis. The Survey used Likert-based responses and dichotomous or categorical responses. Because bone health is a major health concern as a woman ages, the researchers wanted to determine whether younger woman were knowledgeable about the issues that surround osteoporosis. These results could help health educators in developing appropriate materials to better educate younger women about the risk factors of osteoporosis.
Behavioral Observation Research Design
Behavioral observation research design deals with using direct observation of behaviors in a natural setting, rather than relying on self-report data such as questionnaires. It is also known as systematic observation and analysis, by which objective information is collected on the instructional process and analyzed in a meaningful way.
Behavioral observation design: includes the process of collecting objective information by a live observer or through the use of audio or video recording
Behavioral Observational Design techniques are used most frequently in education, when researchers are attempting to understand defined characteristics within a classroom. Usually simple observation behaviors are identified that are easy to record, such as type and quality of teacher feedback, amount of instructional time spent organizing a class or how is it done, amount of practice time students actually get, progressive sequences of the teacher's task, amount of decision making permitted, and student off-task behaviors. When deciding to use behavioral observation techniques as a research method, the researcher should consider the following steps:

    not right by the entrance. Despite every customer passing this area, it is almost always ignored; customers do not actually begin shopping or looking for items until they are a minimum of several feet inside the door. This type of insight is easily and clearly established by waiting, watching, and recording.
    The rest of this chapter will be devoted to: (1) defining observational research and when it is appropriate for use, (2) describing general approaches and specific methods for observation (along with their ethical considerations), and (3) discussing the intricacies of coding and inter-observer reliability.

    What is Observational Research and Why do it?

    In its simplest form, observation can be defined as receiving information through one of the five human senses. By this definition, however, nearly every study of behavior within an environment involves observation. Certainly, watching people explore a space or use a recycling bin is a form of observation, but so too would be viewing the results of cortisol tests or listening to answers from an interview. Given that topics such as interviewing, participant observation, and surveying will be covered elsewhere in this book (mainly Chapter 5 ), this chapter will focus solely on research methods pertaining to direct observation.
    Indirect observation, another important tool for the study of environment–behavior relationships, involves methods such as personal diaries, informants, or trace measures. These will not be examined in depth here, only to say that they can be quite effective. For example, the Rochester Interaction Record (Wheeler & Nezlek, 1977), and related Social Behavior Inventory (Moskowitz, 1994), standardized event-contingent reporting methods (diary methods) are reliable and valid ways to learn about participants’ daily interactions from their own notes. In addition, trace measures (or a lack thereof) caused by erosion, leftovers, adaptations, repairs, or personalizations to a space (Zeisel, 1984) can also be “observed” for information about how the physical environment is used. For example, the wear on a door can be a good indication of where a handle should be situated (Chang & Drury, 2007). This type of indirect measure will also not be elaborated upon in this chapter given that it is particularly useful in the programming and post-occupancy evaluations of buildings (see Chapters 12 and 13

    Definition of Observational Studies
    An observational study design is one in which people are observed to see whether a relationship exists between a risk factor and a disease. The observational study design is the most commonly used design in epidemiology. Its major characteristic is that the study design does not affect the outcome, it only observes what happens. In other words, people are not given any treatment or drug; they are simply observed.
    During the observation, people are grouped by whether or not they have been exposed to the risk factor. The exposure to the risk factor is not affected by the study but is a personal characteristic. For example, current smokers and nonsmokers are categorized into two groups, and what is observed is whether the disease occurs in both groups. No one is encouraged to smoke or to stop smoking.
    Framework and Types of Observational Studies
    The framework of observational study designs is presented in Figure 6.1 . Descriptive studies collect information that describes disease according to person, place, and time; they are used to determine rates of health and disease. Descriptive studies include ecological studies, case studies, and cross-sectional studies. Ecological studies collect information in distinct populations living in specific geographical areas. Cross-sectional studies measure the prevalence rate and are concerned with the presence or absence of disease at the present time. Analytical studies support hypotheses that exposure to a risk factor is related to the development of a disease. Analytical studies include prospective and retrospective designs. Retrospective studies, also known as case-control studies, look at the presence or absence of disease in the past. Prospective studies,
  • How to Design and Report Experiments
    Observational and quasi-experimental methods don’t allow us to unequivocally establish cause and effect in the same way that true experimental designs do, but they are still very useful. Also, a discussion of their limitations helps to demonstrate the strengths of the experimental approach.
    Observational Methods
    One way to find out about a phenomenon is simply to look at it in a systematic and scientifically rigorous way. Personally, I think that psychologists have often jumped in at the deep end, running experiments to find out about some phenomenon before they have collected sufficient observational data on it. Historically, most sciences (biology, physics and chemistry) were preceded by a phase of naturalistic observation, during which phenomena were simply watched in a systematic and rigorous way. Experimentation came later. Psychology has tended to skip the observational phase and tried to go straight into doing experiments. This isn’t always a good thing, since experimentation without prior careful observation can sometimes lead to a distorted or incomplete picture being developed.
    Lessons could be learnt from the way in which biology supplanted comparative psychology as a means of finding out about animal behaviour. In the first half of the 20th century, behaviourism was the dominant method of studying animal behaviour. Innumerable experiments were performed to investigate learning, using a few species (mainly rats and pigeons) and highly artificial tasks (such as lever pressing) performed in very unnatural environments (such as mazes and Skinner Boxes). A lot of useful information has been obtained by using these experimental methods. However, after about 1960, most of the really interesting stuff on how animals behave has come from ethology and sociobiology, movements which have their roots in biology, not psychology.
    One factor in the demise of comparative psychology as a discipline was that its attempts to produce universal laws of learning, that applied to all species including humans, were shown to be flawed. The observational data on a wide range of species that were produced by ethologists drew attention to this by demonstrating that many species show species-specific behaviour patterns as a result of natural selection having adapted their learning abilities to their particular environmental niche. While the study of learning was confined to experiments on a few species under highly constrained conditions, these problems were not apparent and could be overlooked. The ethologists and their observational data showed that the experimental methods used by the psychologists produced data that were highly reliable (in the sense of reproducible) but not necessarily valid (in the sense of providing an accurate picture of what animals can learn in their natural environments).
