Case Study Summary Corporal Colby King is a veteran of an Afghanistan campaign that took place for eight months in 2012. He was honorably discharged six months ago and is having trouble readjusting to his new life. His mother and his girlfriend brought him to the ED after a threat of ending his own life. Cpl. King suffers from a psychological trauma associated with the loss of friends and comrades during the Afghanistan campaign of 2012. He is hesitant to open up to anyone and spends time in the company of his marine friends. Three months ago, Cpl. King suffered a back injury from a motorcycle accident, which leaves him in a condition of constant pain. Additional symptoms include aggressive mood swings, a lack of interest in continuing relationships, and general apathy towards anyone besides his few marine friends. Engaging Cpl. King Merrill (2013) states that the clinician strategy for patients such as Cpl. King, who demonstrate clear signs of suicidal and self-harming behavior, should be based on three principles:   * Friendliness. The clinician is expected to demonstrate a supportive, caring, concerned, and compassionate attitude towards the patient.   * Frankness. The clinician must be direct and candid when talking to the patient about the risks of their behavior. Must not be afraid to ask difficult questions.   * Firmness. The clinician must hold a confident tone and apply pressure when necessary, in order to facilitate a therapeutic process. These behaviors, combined together, will help create a healthy relationship between the patient and the healthcare provider, based on respect, mutual trust, and relational honesty. Establishing rapport with Cpl. King is essential, as he shows signs of aversion towards psychologists. It is recommended to present oneself as a social worker, as the word “psychologist” is a loaded term that often has a negative connotation. Interviewing Strategy The interviewing strategy will implement a normalization process, which would enable extracting important information out of the patient (Rubin, Weiss, & Coll, 2012). The primary sources of information would include interviews of the patient, his family, his marine friends, as well as medical logs and reports of the primary healthcare providers. Some of the critical information to be accessed must include the following (Merrill, 2013):   * Suicidal ideation – determining what triggers suicidal thoughts in a patient.   * Suicidal planning – determining what plans the patient had about his own suicide.   * Means – what means of suicide are immediately accessible to the patient.   * Protective factors – means of suicide prevention.   * Past experiences – the patient’s history of suicide attempts.   * Future expectations – determining the patient’s expectations towards life, the possibility of suicide, and perceived reactions to it. Psychometric Assessment Tools The primary assessment tool for social workers and clinicians dealing with suicide is the Suicide Affect Behavior Cognition Scale (SABCS). It is a six-item scale that assesses the patient based on suicidal affect, behaviors, and cognition (Scott, Whitworth, & Herzog, 2016). It was constructed using the classic test theory and item response theory as primary psychome
