Zagar, R. J., Busch, K. G., Grove, W. M., Hughes, J. R., & Arbit, J. (2009) Looking forward in records of youth abused as infants: risks of homicidal, violent, and delinquent offenses. Psychological Reports, 104, 47–75.

On page 47, line 7 of the Summary should read: “Youth tracked through records 12 years (to M age = 15.17 yr., SD = 1.89)….”

In Table 2, page 54:

For χ² comparisons of Population, Sample, and Combined Abused Infants+Controls, df = 3. The χ² of Groups for Family is 35.7*.

For χ² comparisons of Population, Sample, and Combined Abused Later Homicidal+Controls, df = 3.

For χ² comparisons of Population, Sample, and Combined Abused Later Homicidal+ Abused Later Nondelinquent, df = 3. The χ² of Groups for Family in this section is 8.89f.

In Table 3, page 60, there are 136 Low Socioeconomic Status Abused Infants, and for the two-tailed t-tests, df = 382.

Only values of comparison statistics that are statistically significant are shown in Tables 2, 3, 5, 7, and 8.

In Appendix C on page 75, and in the References, MacDonald (1970) should be McDonald (1970).

In Table 1, page 112:

For χ² comparisons of Population, Sample, and Combined Homicidal+Nonviolent Delinquents, df= 3 for Family and Illnesses, df = 1 for Race subcategories (none significant).

For χ² comparisons of Population, Sample, and Combined Homicidal+Controls, df = 3 for Family and Illnesses, df = 1 for Race subcategories. The χ² of Population and Groups for Family is 21.63*

For χ² comparisons of Population, Sample, and Combined Homicidal+Nonviolent Delinquents, df = 3 for Family (χ² = 20.76*) and Illnesses, df = 1 for Race subcategories.

In Table 2, page 113:

For all two-tailed t-tests, df = 50.

Only statistically significant values of comparison statistics are shown in Tables 1, 2, and 3.

On page 127, in Appendix A and in the References, MacDonald (1970) should be McDonald (1970).
