Assignment 2: LASA 1 – Applying Theory to a Case Study

  1. Select one of the two available video clips to the right. 
    • The video will begin playing immediately.
    • Pause the video and notice under the Clips heading to the right, either you will see the "Case Study of Carol (30:38) or Case Study of Paul (26:40) depending on which video you have selected.
    • Move the video play head to the timestamp of the video. This will be the number in parentheses. 
    • Watch the Case Study 
  2. Choose one of the following theories and use your chosen theory and chosen video clip to complete all of the questions in this assignment.
    • Psychoanalytic
    • Adlerian
    • Client-centered
    • Existential
    • Gestalt
    • Reality
  3. Watch the video clip of a supervisor and therapist discussing the case you have selected.  The information from the video will supplement the information in the write-up. 
  4. Assess the client being described in the video and that client’s related issues using the questions provided.

Directions:

Using only one case study and one counseling theory throughout your paper, provide a detailed response to each of the following questions.  For example, if you chose Carol and Psychoanalytic Theory, you would answer all of the following questions about Carol using the psychoanalytic theory.

  1. Based upon all that you know about your client, identify and describe what in your opinion is your client’s most significant problem? This may or may not be the stated “Reason for referral” that is written at the start of each profile. Give a detailed rationale for your assessment and provide supporting evidence from the profile and/or counseling session video clip.
  2. Identify at least two secondary problems from the client’s profile or video that should be addressed at some point in the counseling process. Explain your rationale in some detail for choosing each of these with supporting evidence from the written profile and/or the video.
  3. Using your chosen counseling theory, describe what your theory says about the possible cause or origin of the primary problem discussed in question 1 above. Here, you are trying to explain the assumptions your chosen theory makes about problems that might be seen in a counseling situation. For example if you assessed your client’s primary problem as low self-esteem, a psychoanalytic therapist would delve into the unconscious whereas an Adlerian would explore family history and a reality therapist would look at choices the person has previously made. Explain in detail by including concepts and terms from your chosen counseling theory to support your perspective.
  4. Explain at least three counseling techniques or core principles from your chosen counseling theory that could be used to address the primary and secondary problems of your client. Explain how each of these techniques or principles would be applied in the counseling session and the expected outcome of each.
  5. Given what you know about your client’s situation, identify one cultural issue that is significant in the client’s life outside of therapy or could become an issue between the client and therapist in the therapy session. After explaining the issue, explain two ways the therapist could sensitively address this cultural issue with the client in a way that that avoids stereotyping or bias. Remember to integrate your chosen theory into the discussion.
  6. If you were to see this client on an ongoing basis, describe the types of change or outcomes you could realistically expect to see in your client, in light of the primary and secondary problems mentioned earlier using your identified approach in therapy. Be specific and show how the process of therapy with this counseling approach would lead to the outcomes you discuss. 

Your paper should be double-spaced and in 12 point, Times New Roman font with normal one-inch margins, written in APA style, and free of typographical and grammatical errors.  It should include a title page with a running head, an abstract and a reference page. The body of the paper should be 6 - 8 pages in length. Submit your response to the M3: Assignment 2 Dropbox byWednesday, May 11, 2016.

Discussion Question: Comparing Three Theories

For this week’s discussion you will consider the scenario below and respond in detail to each of the questions below. Here is the scenario you will use:

Roberta has come to counseling because she is contemplating a divorce from her husband of 12 years. She has been unhappy in her marriage for several years and doesn’t think that she and her husband can rekindle the interest necessary in their relationship to make it work. To complicate the situation, she has been seeing a married co-worker for several months on the sly and is sexually involved. Roberta thinks she loves the man she is having an affair with and would like to marry him. Though he wants to continue seeing her he has made it clear that he is unwilling to end his marriage or break up his family to be with her. Roberta and her husband have three young children and she knows a divorce would be crushing to the children. She’s come to you for counseling to sort through these issues.

1. In your opinion, which of the following counseling theories would you prefer to use to try and help her: Person-centered, Gestalt or Reality? Choose only one and explain your reasoning in detail.

2. Using your chosen theory from question 1, would you go about helping her sort through her confusion? Be sure to bring in concepts from your chosen counseling theory to show how you would specifically work with her.

3. Roberta is looking for answers to questions she feels unable to answer herself because she is so emotionally involved. After she tells you her story she asks you to give your perspective and advice on what she should do. How would you respond to this request? What potential problems might arise if you do give her direct advice? What potential problems might arise if you don’t give your perspective? Be specific and detailed in your response.  What would your chosen counseling theory have to say about giving direct advice?

4. At the end of the session, Roberta is very distraught and asks if you would be available to meet her for coffee later that day to continue the conversation in a more casual environment. Under what circumstances might this be appropriate, if at all? What potential conflicts might this create? Be specific and draw upon information from your text and lecture materials to support your points.
