Question 1

Which of the following is a procedure for statistically combining the results of many different studies?

Accepted Answer

Meta-analysis is the procedure for statistically combining the results of many different studies. Factor analysis is a statistical method used to identify relationships among a large number of variables and regression toward the mean is a phenomenon where extreme values tend to move closer to the mean on subsequent measurements. rTMS is a non-invasive brain stimulation technique that involves the use of magnetic fields to stimulate nerve cells in the brain.

Question 2

Therapists' perceptions of the effectiveness of psychotherapy are likely to be misleading because

Accepted Answer

This is known as the "rosy retrospective bias," where clients tend to recall their improvement more positively after therapy has ended. Therapists may also be biased by this phenomenon since they are often reliant on client feedback to judge the effectiveness of therapy. Additionally, research has shown that therapists' perceptions of their clients' progress often do not match up with objective measures of improvement.

Question 3

Hans Eysenck's summary of 24 early psychotherapy outcome studies suggested that patient improvement was not necessarily the result of

Accepted Answer

Eysenck's summary suggested that patient improvement was not necessarily due to psychotherapy, as he argued that the rates of improvement were similar to those who did not receive therapy, implying other factors like spontaneous recovery might be responsible.

Question 4

A trained therapist who uses psychological techniques to assist someone to overcome excessive anxiety would generally be best described as a

Accepted Answer

A psychotherapist is a trained professional who uses psychological techniques to help individuals overcome their emotional and mental health issues, such as anxiety. Psychoanalysts and psychodynamic therapists focus on unconscious desires and drives as the root cause of mental health issues, while a psychopharmacologist prescribes medication for psychological disorders.

Accepted Answer

The answer of Cognitive therapies have achieved especially favorable results...

Question 6

Clients' perceptions of the effectiveness of psychotherapy are often misleading because clients

Accepted Answer

The answer of Clients' perceptions of the effectiveness of psychotherapy...

Question 7

Which of the following is most likely to contribute to inflated perceptions of the effectiveness of psychotherapy?

Accepted Answer

Regression toward the mean is a statistical phenomenon where extreme scores on a measure tend to move closer to the average on subsequent measurements. If individuals seek psychotherapy during a particularly low point in their lives, they may naturally experience some improvement simply due to regression toward the mean, leading them to believe that the therapy was more effective than it actually was.

Question 8

Psychotherapy is MOST likely to be effective in freeing

Accepted Answer

The answer of Psychotherapy is MOST likely to be effective...

Question 9

The best psychotherapy outcome studies are randomized clinical trials comparing treatment groups with ________ groups.

Accepted Answer

Control groups are essential in order to establish whether or not a particular form of intervention is effective. By comparing treatment groups with control groups, researchers are able to establish whether observed improvements in the treatment groups are due to the intervention or to other factors such as the passage of time, the placebo effect, or natural improvement.

Question 10

The most convincing evidence for the effectiveness of psychotherapy comes from

Accepted Answer

Meta-analyses are considered the gold standard for evaluating the effectiveness of interventions because they statistically analyze the results of multiple studies to determine whether the intervention has a significant, consistent effect. In the case of psychotherapy, meta-analyses have consistently shown that it is an effective treatment for a variety of mental health conditions. Client satisfaction and therapist perceptions of improvement are important factors but are subject to biases and limitations in their assessment. The reactions of family and friends are also useful to consider but are not a reliable or objective measure of the effectiveness of psychotherapy.

Question 11

Which of the following treatment approaches has received little or no scientific support?

Accepted Answer

While ECT, exposure therapies, and aversive conditioning have some degree of scientific evidence supporting their effectiveness, energy therapies (such as Reiki or therapeutic touch) have little to no scientific support for their use in treating mental health concerns.

Question 12

Increasingly, insurer and government support for mental health services requires

Accepted Answer

Insurer and government support for mental health services often require the use of evidence-based practices, meaning therapeutic interventions that have been shown through research to be effective for specific mental health conditions. Client-centered therapy and stress inoculation training are specific types of therapies and may not be appropriate for every individual or condition. Token economy is a type of behavioral intervention used primarily in institutional settings and may not be relevant for all mental health services.

Question 13

Research on the effectiveness of psychotherapy indicates that

Accepted Answer

Research consistently shows that clients are generally satisfied with the effectiveness of therapy. However, this does not necessarily mean that therapy is always effective or that clients' perceptions are the best evidence available for its effectiveness. Additionally, research has shown that therapy is generally more effective than simply talking to a friend, so option D is incorrect. Finally, while some clients may underestimate their progress in therapy, this is not a universal finding and does not represent the overall effectiveness of therapy.

Question 14

Although Soren once scored 37 points during a single high school basketball game, he was subsequently unable to beat or match this record no matter how hard he tried. His experience may be at least partially explained in terms of

Accepted Answer

Regression toward the mean refers to the tendency for extreme scores or outcomes to be followed by scores or outcomes that are closer to the mean or average. In this case, Soren's initial score of 37 points was an extreme outcome, and it is likely that subsequent performances would be closer to his typical level of performance, rather than repeating such an exceptional performance.

Question 15

The beneficial consequence of a person's expecting that a treatment will be therapeutic is known as

Accepted Answer

The beneficial consequence of a person's expecting that a treatment will be therapeutic is known as the placebo effect. This refers to the psychological phenomenon where people experience positive effects from a treatment, even when the treatment itself has no actual therapeutic value. It is often attributed to the person's belief or expectation that the treatment will work. This effect is commonly used in medical research as a way to control for the influence of expectation and other psychological factors on treatment outcomes.

Question 16

Klaus is a psychology graduate student who wants to determine whether electroconvulsive therapy is an effective treatment for schizophrenia. To combine the results of numerous published studies on this issue, Klaus should use a technique called

Accepted Answer

Meta-analysis is the technique used to combine the results of numerous published studies on a particular topic, allowing for a more comprehensive and reliable understanding of the effectiveness of a treatment or intervention. A meta-analysis involves analyzing and synthesizing data from multiple studies to draw overall conclusions and identify patterns or trends across a broader range of data. Therefore, Klaus should use meta-analysis to determine if electroconvulsive therapy is an effective treatment for schizophrenia.

Question 17

Which phenomenon refers to the tendency for extraordinary or unusual events to be followed by more ordinary events?

Accepted Answer

Regression toward the mean refers to the statistical phenomenon where an extreme score or event is likely to be followed by a less extreme score or event. This can happen for natural fluctuations or due to regression to an individual's average performance.

Question 18

Because Gretchen is afraid of contracting infectious diseases, she compulsively avoids shaking people's hands or touching doorknobs. Research suggests that an especially effective treatment for her difficulty would involve

Accepted Answer

Gretchen's fear involves specific behaviors (avoiding handshakes and touching doorknobs), which can be addressed through behavior therapy. Specifically, exposure therapy and response prevention have been found to be effective in treating OCD and related disorders involving germophobia.

Question 19

A Consumer Reports survey found that the level of satisfaction with psychotherapy among clients

Accepted Answer

The survey found that satisfaction levels were not significantly affected by whether therapy was conducted in a group or individual setting.

Question 20

Statistical summaries of psychotherapy outcome studies indicate that

Accepted Answer

Statistical summaries of psychotherapy outcome studies consistently show that there is no single form of therapy that proves consistently superior to the others. However, this does not mean that psychotherapy is no more effective than talking to a friend or that it harms just as many people as it helps. In fact, the majority of studies show that psychotherapy is effective in treating many different mental health conditions. It is also possible to measure the effectiveness of psychotherapy, although this can sometimes be challenging due to the complexity of the therapeutic process and the individual differences between clients.
