Life-threatening illness now qualifies as a precipitating stessor for posttraumatic stress disorder (PTSD). We examined the validity of the PTSD Checklist-Civilian Version (PCL-C; Weathers, Litz, Herman, Juska, & Keane, 1993), a brief 17-item inventory of PTSD-like symptoms, in a sample of 111 adults who had undergone bone marrow transplantation an average of 4.04 years previously. Exploratory factor analysis of the PCL-C identified four distinct patterns of symptom responses: Numbing-Hyperarousal, Dreams-Memories of the Cancer Treatment, General Hyperarousal, Responses to Cancer-Related Reminders and Avoidance-Numbing. Respondents meeting PTSD symptom criteria on the PCL-C had significantly lower physical, role, and social functioning, greater distress and anxiety, and significantly more intrusive and avoidant responses than individuals who did not meet PTSD symptom criteria.

The authors tested a mediational model of temperament dimensions and substance use with a sample of 1,826 urban adolescents, M age 12.3 years. Five scales from the Revised Dimensions of Temperament Survey (DOTS-R) were administered together with measures of substance (tobacco, alcohol, marijuana) use and measures of related variables derived from a self-regulation model. Unique contributions to substance use were found for DOTS-R dimensions of high activity level (positively related) and positive mood (inversely related). High activity level and low positive mood were also related to lower levels of parental support. Analyses, including multiple regression and structural modeling, identified generalized self-control, maladaptive coping (anger and helplessness), novelty seeking, and affiliation with peer substance users as mediating the effect of temperament on substance use, with control for effects of parental support. Parental support was inversely related to substance use through several pathways. Implications for the theory of vulnerability are discussed.

We studied 32 coronary bypass patients to examine the effect of hypnosis on recovery from surgery. The patients were assessed for hypnotizability with the Hypnotic Induction Profile (HIP) and assigned to experimental groups with a random stratification procedure to equate for differences in hypnotizability, age, and severity of illness. We taught patients in groups one and two formal hypnosis with different treatment strategies; patients in group three were not taught formal hypnosis or a treatment strategy. Scores on the HIP were significant predictors of recovery, independent of experimental treatment with formal hypnosis. Patients who scored "Midrange" stabilized more quickly in the intensive care unit (ICU) than those who scored "High" or "Low" (p = < .05). Patients who scored "High" had more labile blood pressure in the ICU compared to the "Midrange" and "Lows" (p = < .05). Measured hypnotizability was associated with the recovery sequence from surgery.
