Correlations versus causation?

       Person‐centered designs

      Person‐centered research designs are used to examine the effects of risk/protective factors on subgroups of a sample, such as genotypes, personality, neighborhood, or other grouping factors and their developmental trajectories (Bergman & Magnusson, 1997). Advanced statistical strategies (growth mixture modeling, group‐based trajectory modeling) are used to study continuities and trajectories of behaviors as well as examine subgroups and how they change over time.

      RESEARCH METHODOLOGIES

      In this chapter, we have discussed how developmental psychopathology encompasses a wide range of disciplines and methods to answer our big questions. Improvements in brain imaging techniques and genetics have advanced research in these areas and development of psychopathology as a result. This section will briefly explain some of the methods discussed in later chapters.

       Examining genetic factors

      There are three main types of genetic studies that have increased our understanding of relationships between genes and behavior. The first is behavioral genetics, which separates variability in behavioral traits (e.g., aggression, anxiety) into heritability, environment, and Gene × Environment mechanisms. The second method of studying genetics is molecular genetics, which examines specific alleles, genetic markers, and gene expression patterns that are associated with psychopathology. Lastly, epigenetics refers to changes in gene expression due to environmental influences.

       Neuroimaging

      This chapter provided an introduction to the developmental psychopathology framework. We first discussed the history of the developmental psychopathology model and discussed how it provided a new model for better understanding changes and individual differences in psychopathology across the lifespan. We provided an overview of several key tenets of the framework. Finally, we outlined various research designs and methodologies that have been employed to shed light on DP questions. An emphasis of this chapter is how the application of this framework to the study of psychopathology can be leveraged to support improved detection, diagnosis, prevention, and treatment.

      1 How does studying normal and abnormal behavior inform understanding of developmental psychopathology?

      2 Discuss how risk/resilience factors relate to psychopathology and provide an example of each.

      3 Explain at least three levels of analyses that researchers study and how you would research a psychological disorder/concept at each level.

      4 Discuss three research methods and at least one advantage and limitation of each method.

      5 Discuss the nature vs. nurture debate and provide evidence for each side.

      Behavioral genetics separates variability in behavioral traits (e.g., aggression, anxiety) into heritability, environment.

      Cross‐sectional design occurs when researchers do not sample variables over time. Data are collected at one time point.

      Developmental milestones are indicators for how an individual has adapted and is functioning in their environmental context.

      Developmental psychopathology is the study of the origins and course of individual patterns of behavior.

      Epigenetics refers to changes in gene expression due to environmental influences.

      Equifinality refers to the idea that many different pathways or early experiences may lead to the same outcome or condition.

      Gene–environment interactions occur when both genes and the environment predict behavior or other outcomes. In a statistical model, GxE refers to when the effect of a gene depends on an environmental factor or the effect of the environment depends on genotype.

      Heterotypic continuity is defined as stability of an underlying construct that is exhibited differentially across development; that is, different disorders predict one another over time (e.g., anxiety predicting later depression).

      Homotypic continuity is defined as stability in the same or similar behavioral responses over time; that is, the same disorder predicts itself over time (e.g., earlier depression predicting later depression).

      Macro factors such as family environment, school, peer interactions, community, and cultural context.

      Magnetic resonance imaging (MRI) is a neuroimaging technique that is widely used because it is non‐invasive and can capture properties about brain structure and
