According to classical test theory, if the observed variance of a test is 50 and the true variance is 40, what is the estimated reliability of the test?
a. 0.40
b. 0.50
c. 0.80
d. 0.90
I selected C for my answer 40/50 is the .80
If the correlation between one’s interest in statistics and being a “fun date” was –0.70, it would mean that:
a. The higher someone’s interest was in statistics, the more likely it would be that he or she is a fun date
b. The higher someone’s interest was in statistics, the less likely it would be that he or she is a fun date
c. There is a 70% chance that someone with an interest in statistics is a fun date
d. There is a 30% chance that someone with an interest in statistics is a fun date
I selected C for this question because correlations or possibility of this occurring is 70 %
Joe had a score of 72 on the Counseling Aptitude Scale, and the standard error of measurement of the scale is 3. Where would we expect Tom’s true score to fall 99.5 percent of the time?
a. 71 to 73
b. 69 to 75
c. 66 to 78
d. 63 to 81
I selected A because of error is 3
Which of the following would be the most appropriate method of identifying and selecting psychometrically sound assessment instruments?
a. Using only assessments with which you have been trained during graduate school
b. Consulting the Mental Measurements Yearbook or Tests in Print
c. Visiting the American Psychological Association website for a review of recently published tests
d. Consulting with your professional mentor
I selected B because this allows one to look at reliability and client population
Whenever possible, the interpretation of assessment results should involve the use of:
a. Precise psychometric terms exclusively in order to present the results in a professional manner
b. Vague terms so that the client does not think the results are infallible
c. Descriptive terms that accompany the numerical scores to aid in the understanding
d. Only the numerical scores, as other information may confuse the client
I selected C because clinical talk can be confusing to the client and must be interpret in an universal manner
In conducting an interview with a client from another culture, the counselor should:
a. Conduct the interview using closed-ended questions
b. Consider the degree to which self-disclosure is encouraged in that culture
c. Use a multiple-choice format in the interviewing
d. Use checklists or rating scales rather than interviews
I selected B because some clients from different cultures may avoid sharing personal information
An introverted client who uses senses to perceive information, uses feelings to process information, and whose orientation to the outer world is judgment would have which of the following Myers-Briggs personality types?
a. ISFJ
b. INTJ
c. ISTP
d. ENFJ
I selected a since I=introvert S= person who uses senses to perceive information F= individual primarily uses personal or social values in making judgments J= using either thinking or feeling or is it B just introvert
Projective techniques, as distinguished from other personality instruments, have usually been designed to measure the:
a. Level of aggression in terms of psychodynamic theory
b. More typical and superficial aspects of personality
c. Client’s level of repression and hostility
d. Covert and underlying aspects of personality
I select D because this method will eventually disclose individuals personal as the get more comfortable with counselor
In order to use a projective technique to make a clinical decision, the counselor should be:
a. Trained extensively in using and interpreting the technique
b. Knowledgeable of the five factors of personality
c. Trained extensively in personality disorders
d. Knowledgeable of psychoanalytic theory
I selected A
If a client has a personality disorder, it:
a. Will be readily apparent in the first session
b. Can be readily assessed with the NEO-PI-3
c. Will become slowly evident through recurrent themes (e.g., relationship difficulties) and through the client’s interactions with the counselor
d. Is typically associated with legal difficulties and counselors should ask clients about their legal record in the first session
I selected c because counselor will begin to see patterns of abnormal behaviors
For the first question about classical test theory, to calculate the estimated reliability of the test, you need to use the formula:
Estimated reliability = (True variance) / (Observed variance)
In this case, the true variance is 40 and the observed variance is 50. Plugging these values into the formula, you get:
Estimated reliability = 40 / 50 = 0.80
So the correct answer is C, 0.80.
For the second question about correlation, a correlation coefficient of -0.70 means that there is a negative relationship between interest in statistics and being a "fun date". It indicates that as interest in statistics increases, the likelihood of being a "fun date" decreases. So the correct answer is B, "The higher someone’s interest was in statistics, the less likely it would be that he or she is a fun date."
For the third question about the standard error of measurement, to determine where Tom's true score would fall 99.5 percent of the time, you need to use the standard error of measurement (SEM). The SEM represents the average amount of error in a test score.
To calculate the range, you can use the formula:
Range = Tom's score ± (2.58 * SEM), where 2.58 is the z-score corresponding to a 99.5% confidence level.
In this case, Tom's score is 72 and the SEM is 3. Plugging these values into the formula, you get:
Range = 72 ± (2.58 * 3) = 72 ± 7.74 = 64.26 to 79.74
So the correct answer is D, "63 to 81".
For the fourth question about identifying and selecting psychometrically sound assessment instruments, the most appropriate method would be to consult the Mental Measurements Yearbook or Tests in Print. These resources provide comprehensive information on a wide range of assessments, including their psychometric properties. So the correct answer is B.
For the fifth question about the interpretation of assessment results, it is important to use descriptive terms that accompany the numerical scores to aid in understanding. Using only precise psychometric terms may not be easily understood by clients, and using vague terms may lead to misinterpretations. So the correct answer is C.
For the sixth question about conducting an interview with a client from another culture, it is important to consider the degree to which self-disclosure is encouraged in that culture. Some cultures may value privacy and avoid sharing personal information, while others may encourage more openness. So the correct answer is B.
For the seventh question about the Myers-Briggs personality types, an introverted client who uses senses to perceive information, uses feelings to process information, and whose orientation to the outer world is judgment would have the ISFJ type. ISFJ stands for Introversion, Sensing, Feeling, and Judging. So the correct answer is A.
For the eighth question about projective techniques, they are designed to measure the covert and underlying aspects of personality. They aim to reveal unconscious or subconscious thoughts, feelings, and conflicts. So the correct answer is D.
For the ninth question about using a projective technique, the counselor should be trained extensively in using and interpreting the technique. Projective techniques require specialized knowledge and skill to administer and interpret accurately. So the correct answer is A.
For the tenth question about personality disorders, they will become slowly evident through recurrent themes, such as relationship difficulties, and through the client's interactions with the counselor. They are not typically associated with legal difficulties, and it may take time for patterns of abnormal behavior to emerge. So the correct answer is C.
