Two from the bank, answered.

Real items, with the answer marked and the reason written out — the same format as all 123.

Ethical, Legal, and Professional Issues

A psychologist ended therapy with a client 18 months ago. The former client now proposes a romantic relationship. Under APA Ethics Code Standard 10.08, what applies?

  1. AIt is permitted after one year with peer consultation
  2. BIt is permitted because the former client initiated it
  3. CIt is prohibited because fewer than two years have passedCorrect
  4. DIt is permitted because therapy has formally ended

Why: APA Standard 10.08(a) sets a minimum of two years after therapy ends before any sexual intimacy with a former client could even be considered. Formal termination, who initiates the contact, and consultation do not shorten that period.

Assessment and Diagnosis

A test has a standard deviation of 15 and a reliability coefficient of .91. What is its standard error of measurement?

  1. A13.65
  2. B9.0
  3. C1.35
  4. D4.5Correct

Why: SEM = SD x the square root of (1 - reliability) = 15 x sqrt(1 - .91) = 15 x sqrt(.09) = 15 x .30 = 4.5. Multiplying 15 by .09 gives 1.35 and 15 by .91 gives 13.65, both of which skip the square root; 9.0 doubles the correct value.
