Assessment, Statistics, and Research

The chart based on data from CDC 2015 provides an example of tracking three trends over time. The bars indicate the percentage of births to unmarried women. The upper teal line represents the median age at first marriage and the orange broken line indicates median age at first birth. Notice the "crossover" of the two lines referring to first birth and first marriage. Note also the stabalized trend for births to unmarried women easily visible on the bar portion of the chart. About 40% of women are unmarried when their children are born.

The Adult Hope Scale The Adult Hope Scale developed by C. R. Snyder of the University of Kansas is an easy to use measure of hope. The original scale has 12-items, which measure two dimensions of hope based on hope theory. Four measure agency and four measure pathways--the other four are distractors. The agency concept measures the capacity to focus energy on a goal. The pathways concept assesses plans to achieve goals. In recent studies, the four distraction items are often dropped leaving 8-items. Researchers often use the total score for the 8-items as a measure of trait (aka dispositional) hope. Find Snyder's The Psychology of Hope I have also included a Spanish language measure of hope in this post. Here's the text we (Sutton et al., 2018) used to refer to the scale along with our findings. The items used a response format of 1 =  definitely false  to 8 =  definitely true . A sample item is, “I meet the goals I set for myself.” Snyder et al. (1991)...

When counselors and psychologists report test scores, they often report one of the scores found in the table below. When several tests are used, it is helpful to know how the scores compare from one test to another. A good place to begin is to locate the average score-- that's the row where z = 0. Then look at the broad middle range between z = -1 and z = 1. About 68% of people score between z = -1 and z = 1. Intelligence Tests use Standard Scores abbreviated as SS. These scores take the place of the old IQ score. An average IQ is 100 -- about 68% of people score between 85 and 115. Here's a table from Appendix B of Applied Statistics: Concepts for Counselors Each row contains the equivalent score on a different scoring system. For example, a z -score of 1 equals a T score of 60, and a standard score of 115. The score is at the 84 th percentile. z T Standard Percentile Ra...

Intelligence tests (IQ tests) are in the news lately as people banter about terms from many decades ago. IQ tests are widely used because they measure the ability of people to solve various problems, predict academic achievement, and help with job placement in some settings. The tests also help neuropsychologists assess functioning in people with impairments due to head injuries and brain diseases. During part of my childhood, I passed a facility where American IQ testing began. I saw people on swings and on the grounds of the Vineland Training school in Vineland NJ. It turns out that a little over 100 years ago, American psychologist, Henry Goddard, brought a test by French scientist, Alfred Binet , to the New Jersey Training School for Feeble-Minded Girls and Boys in Vineland, NJ. The test was modified and widely used in the U.S. What tests are used today? Today, a number of tests are available in the US and elsewhere. Popular American tests are the Wechsler Intelligenc...

Can you answer these questions that every counselor ought to know? Choose the BEST available answer. I'll post the answers below. 1. If the correlation between a test of intelligence and a test of achievement is usually between .88 and .92, how well can you use the intelligence test results to predict achievement test results? A. Very well B. Moderately well C. Not well at all D. None of the above 2. A personality test score was high on a scale of Extraversion. The validity of the Extraversion scale was reported as .52 to .57 compared to similar tests. How much confidence should the person have that their score is "valid?" A. A high degree B. A moderate degree C. A low degree D. None of the above 3. School counselors administered a questionnaire to 1,000 students. They calculated results for answers about four school improvements rated on a scale of 1 to 5. Most of the scores were in the range of 18 to 20. The counselors reported a mean rating o...
