1 Correlational Design Emma VanderPan Master of Forensic Psychology, Walden University FPSY 6115-4: Underst Foren Psyc Resrch Dr. Latifses April 4, 2024
2 Correlational Design Correlational design refers to when two variables are related linearly. They have a direct effect on the other whether positive or negative. It is able to determine the strength of the relationship. However, it cannot speak to the cause and effect, nor can it accurately describe curvilinear relationships. The Stability of Psychopathy Across Adolescence Diagnosing juveniles with psychopathy is a strong debate among clinicians in the psychology/psychiatry fields due to expected developmental changes throughout time (Lynam et al., 2009). The study in this article examines the stability of psychopathy across childhood and adolescence. They are able to use a variety of instruments including the Childhood Psychopathy Scale (CPS) and other mixed models. They examined reliability, individual stability, mean-level stability, and predictive utility of juvenile psychopathy of age in over 1500 boys ages 7 to 17 (Lynam et al., 2009). Many clinicians believe that psychopathy would reduce as these children age. However, the results that this negative correlation would be incorrect. Psychopathy increased at a very small amount which showed a low positive correlation between psychopathy and age maturity (Lynam et al., 2009). They used several intraclass correlations to compare the results across a 5-year period. This allowed them to see a fitted trend for each risk group. There were some limitations to this study. By using parents as the reporters at each age, there could be signs of negative or positive bias (Lynman et al., 2009). Another limitation is the focus solely on boys and did not include any girls. Intelligence and Psychopathy: a correlational study on insane female offenders There is debate surrounding the relationship between psychopathic traits and intelligence levels. The majority of studies on psychopathic traits are from primarily male offenders. This
3 study looks to investigate the correlation between these traits on a female inmate population. They selected 56 female offenders (Spironelli, 2013). To assess psychopathic traits, they utilized the Hare Psychopathy Checklist Revised (PCL-R) (Spironelli, 2013). In order to measure fluid intelligence, they used Raven’s Progressive Matrices (RPM). They showed a negative correlation between psychopathic traits and intelligence scores (Spironelli, 2013). Due to the correlational approach, the researchers were able to investigate the correlations between the intelligence scores and each of the four PCL-R subscales. They all showed equal distribution. However, due to the small sample size, the study is limited.
