Sample Answer



  • Theory: A theory is a set of interrelated ideas that explain a phenomenon. Theories are based on evidence and are constantly being tested and refined.
  • Concept: A concept is a mental construct that represents an idea or object. Concepts can be concrete or abstract.
  • Hypothesis: A hypothesis is a tentative explanation for a phenomenon. Hypotheses are often based on theories and are tested through research.

In Widom and Kuhns’s (1996) study, the concept of childhood abuse was treated as multidimensional. This means that the researchers considered the different ways in which childhood abuse can manifest itself, such as physical abuse, emotional abuse, and neglect. They also considered the different effects that childhood abuse can have on children, such as psychological problems, substance abuse, and criminal behavior.

Here are some other independent and dependent variables that could have been considered in Widom and Kuhns’s research:

  • Independent variables:
    • Gender
    • Race/ethnicity
    • Socioeconomic status
    • Family structure
    • Parental mental health
  • Dependent variables:
    • Adult criminal behavior
    • Adult psychological problems
    • Adult substance abuse
    • Adult educational attainment

To operationalize these variables, the researchers would need to define them and develop ways to measure them. For example, the variable “gender” could be operationalized by asking participants to identify their gender. The variable “socioeconomic status” could be operationalized by using a measure such as income or education level.

The findings of Widom and Kuhns’s research showed that childhood abuse is a significant risk factor for adult criminal behavior, psychological problems, and substance abuse. The researchers also found that the effects of childhood abuse are more pronounced in women than in men.

The statistical data in Widom and Kuhns’s research were presented clearly and discussed in detail. The results were substantively important because they provide evidence of the long-term negative consequences of childhood abuse.

Here are some additional thoughts on the research:

  • The study was conducted with a relatively small sample size, so the findings may not be generalizable to the larger population.
  • The study did not control for other factors that could have influenced the results, such as parental substance abuse or mental health problems.
  • Future research should be conducted with a larger sample size and should control for other potential confounding variables.

Overall, Widom and Kuhns’s research provides important insights into the long-term effects of childhood abuse. The findings of this study should be considered by policymakers and practitioners who are working to prevent and address child maltreatment.
