The Treatment of Missing Data
Comparing an Individual's Test Score Against Norms Derived from Small Samples
The standard method for comparing an individual's test score with a normative sample involves converting the score to a z score and evaluating it using a table of the area under the normal curve. When the normative sample is small, a more appropriate method is to treat the individual as a sample of N = 1 and use a modified t test described by Sokal and Rohlf (1995). The use of this t test is illustrated with examples and its results compared to t…
When Mom or Dad has cancer
This study assessed anxiety/depression and stress response symptoms in adult cancer patients (n = 117), spouses (n = 76), and their children (n = 110, ages 6 to 30 years old) near the patients' diagnoses to identify family members at risk for psychological maladjustment. Patients' and family members' distress was related to appraisals of the seriousness and stressfulness of the cancer but not related to objective characteristics of the disease. P…
Parent and child stress and symptoms
This study assessed major and daily stressful life events and psychological symptoms in a sample of young adolescents and their parents. The relation between major life events and symptoms was mediated by daily stressors for parents and their young adolescent children. Children's emotional and behavioral problems were associated with fathers' psychological symptoms but not with mothers' symptoms. Both mothers' and fathers' symptoms were associate…
Daily and major life events
The hypothesis that negative daily events mediate the relationship between major negative events and psychological symptomatology was tested using a three-wave, three-variable panel design. Measures of major and daily life events and psychological symptomatology were administered to 58 older adolescents at three time points during the transition from high school to college. The results indicated that the pathways from major life events to daily e…
Nonorthogonal Analysis of Variance
There has been considerable debate in the literature concerning the "appropriate" method for calculating least squares analysis of variance with unequal sample sizes. It is argued here that the choice of the appropriate method depends upon the question the experimenter wants to answer about the data. The different questions reflect different null hypotheses. An example is presented to demonstrate the practical effects of using two alternative met…
Association rules in the prediction of recall from free-association matrices
Correlations within methods (SR or FR) between criteria 28 days apart are substantially higher than correlations between methods at 2 min. or at 28 days. Stimulation, then, imposes its own particular alignment of items during recall. A substantial number of associative predictors can be computed by reference to free-association norms, many of which, but not all, are interrelated. These predictors suggest processes which may be responsible for rec…
