A short form of the Posttraumatic Growth Inventory

Abstract A short form of the Posttraumatic Growth Inventory (PTGI-SF) is described. A sample of 1351 adults who had completed the Posttraumatic Growth Inventory (PTGI) in previous studies provided the basis for item selection. The resulting 10-item form includes two items from each of the five subscales of the original PTGI, selected on the basis of loadings on the original factors and breadth of item content. A separate sample of 186 completed the short form of the scale (PTGI-SF). Confirmatory factor analyses on both data sets demonstrated a five-factor structure for the PTGI-short form (PTGI-SF) equivalent to that of the PTGI. Three studies of homogenous clinical samples (bereaved parents, intimate partner violence victims, and acute leukemia patients) demonstrated that the PTGI-SF yields relationships with other variables of interest that are equivalent to those found using the original form of the PTGI. A final study demonstrated that administering the 10 short-form items in a random order, rather than in the fixed context of the original scale, did not impact the performance of the PTGI-SF. Overall, these results indicate that the PTGI-SF could be substituted for the PTGI with little loss of information.

GENDER DIFFERENCES IN SELF-REPORTED POSTTRAUMATIC GROWTH: A META-ANALYSIS

A meta-analysis was conducted to examine the direction and magnitude of gender differences in self-reported post-traumatic growth. Results from 70 studies (N = 16,076) revealed a small to moderate gender difference (g = .27, 95% CI = .21 -.32), with women reporting more posttraumatic growth than men. Moderator analyses were then conducted to identify possible sources of these differences. The following moderators were examined: mean age of sample, measure used, nature of the stressful event, language of the measure, and type of sample (i.e., community samples, college students, or mixed). The only significant moderator was age, with women reporting incrementally more posttraumatic growth as the mean age of the sample increased (B = .004, p < .01, SE = .001, Q = 9.13). To check for publication bias, effect sizes were compared across published and unpublished research. The size of the gender difference was not significantly different between published (g = .30, 95% CI = .23 -.38) and unpublished (g = .22, 95% CI = .12 -.31) studies. The present findings indicate that modest, but reliable gender differences exist in posttraumatic growth even when unpublished data are included in the analyses. Possible explanations for these findings and suggestions for future research are discussed.

Assessing posttraumatic cognitive processes: the Event Related Rumination Inventory

Abstract Cognitive processes in the aftermath of experiencing a major life stressor play an important role in the impact of the event on the person. Intrusive thoughts about the event are likely to be associated with continued distress, while deliberate rumination, aimed at understanding and problem-solving, should be predictive of posttraumatic growth (PTG). The Event Related Rumination Inventory (ERRI), designed to measure these two styles of rumination, is described and validation information is provided. Using a college student sample screened for having experienced highly stressful life events, data were obtained (N=323) to conduct an exploratory factor analysis that supported the two factors of the ERRI. Separate confirmatory factor analyses (CFA) on two additional samples (Ns=186 and 400) supported a two-factor model. The two ERRI factors were validated by comparison with related variables and by assessing their contributions to predicting distress and PTG in two samples (Ns=198 and 202) that had been combined to conduct the second CFA. Data indicate the ERRI has solid psychometric properties, captures variance not measured by stable differences in cognitive styles, and the separate factors are related to posttraumatic distress and growth as predicted by existing models of PTG.

The Core Beliefs Inventory: a brief measure of disruption in the assumptive world

Abstract Stressful events that disrupt the assumptive world can force people to make cognitive changes to accommodate these highly stressful experiences. As fundamental assumptions are reestablished, many people report changes and experiences that reflect posttraumatic growth (PTG). The present research describes the development of the Core Beliefs Inventory (CBI), a brief measure of disruption of the assumptive world developed for use in applied research and clinical settings. Three studies, two using college samples (Study 1, n=181 and Study 2, n=297 time 1; 85 time 2) and the third using leukemia patients (Study 3, n=70 time 1; 43 time 2), assessed the utility of the CBI to predict PTG in both cross-sectional and longitudinal designs. Relationships between the CBI and measures of self-reported PTG and well-being indicate that the CBI has construct validity, acceptable test-retest reliability, and very good internal consistency. The CBI may be a useful tool in investigating predictions about the effects of stressful experiences on an individuals assumptive world, PTG, and successful adaptation.

Predictors of posttraumatic growth in women with breast cancer

Posttraumatic growth (PTG) is defined as ‘positive psychological change experienced as a result of a struggle with highly challenging life circumstances’. The current study examined change in PTG over 2 years following breast cancer diagnosis and variables associated with PTG over time.

A Longitudinal Investigation of Posttraumatic Growth in Adult Patients Undergoing Treatment for Acute Leukemia

An acute leukemia diagnosis can be an extremely stressful experience for most patients. Posttraumatic growth (PTG) is positive psychological change experienced following a struggle with highly challenging life circumstances. The current study is the first longitudinal investigation of predictors of PTG and distress in adult acute leukemia patients undergoing induction chemotherapy. Findings suggest that these patients report PTG, and levels of PTG appear to increase over the weeks following leukemia diagnosis and induction chemotherapy. Variables associated with higher total PTG scores over time included greater number of days from baseline, younger age, and greater challenge to core beliefs. Variables associated with higher distress included greater number of days from baseline, greater perceived cancer threat, higher symptom severity, and lower spiritual well-being. Results underscore the critical role that examination of one’s core beliefs may play in the development of PTG over time.

Educational Outcomes in a System of Care for Children With Emotional Disturbance

In North Carolina, only 69% of high school students graduate in 4 years; however, recent data suggest that only 42% of students with mental and emotional disabilities graduate. MeckCARES, a system of care (SOC) in Mecklenburg County, North Carolina, is designed to serve youth with severe emotional disturbances and their families. The SOC philosophy is a prominent family-focused approach intended to provide comprehensive, coordinated networks of services, tailored to the needs of the child and family, while emphasizing the strengthening of natural community supports. In addition to other mental health objectives, a particular goal of MeckCARES is to address specific school-based needs of system-identified youth to improve educational outcomes and reduce the risk of dropping out. This study sought to assess empirically the impact that enrollment in MeckCARES has on graduation precursors; namely, grades, suspensions, and absences. This study found that, on average, enrollment in MeckCARES is not associated with positive changes in educational variables. Implications of these findings are discussed, as are future directions. For example, additional research is needed with more sensitive measurement and data collection procedures (i.e., access to graduation rates and Medicaid information) to adequately assess the impact of enrollment in MeckCARES on educational outcomes.

“The Keepers of Stories”: Personal Growth and Wisdom Among Oncology Nurses

This study examined whether oncology nurses experience personal growth and wisdom as a result of caring for patients. Using a grounded theory approach, 30 nurses were interviewed regarding their experiences caring for cancer patients. Every nurse in this sample cited at least one example of growth and wisdom. Subthemes of personal growth were largely consistent with the documented domains of posttraumatic growth and included appreciation of life, new perspective on life, relating to others, spiritual/religious growth, and personal strength. Subthemes of wisdom were more varied, reflecting the diversity of this construct in the context of nursing. Benevolence arose as a unifying theme between personal growth and wisdom, with subthemes centering on altruistic attitudes and behavior toward patients and the greater community. Findings suggest that nurses develop personal growth, wisdom, and benevolence as a result of the emotional connections formed with patients and the subsequent struggle to cope with their loss. This process accords well with findings in other populations experiencing trauma and adversity directly.

Using Latent Growth Curve Modeling to Examine Changes in Mental Health Outcomes for Children Enrolled in a System of Care

MeckCARES, a system of care (SOC) in Mecklenburg County, North Carolina, is designed to serve youth with severe emotional disturbances and their families. This study employed latent growth curve (LGC) modeling to examine (a) the degree to which youth improved on indicators of adjustment over the course of the first year of enrollment in MeckCARES, and (b) the services or demographic variables associated with individual differences in the rate of change over time. Participant caregivers (N = 121) reported on 3 major indicators of youth adjustment at baseline, 6-month follow-up, and 12-month follow-up. Primary analyses indicated that there was a modest yet significant improvement in all 3 outcome measures over the first year of enrollment in MeckCARES. Additional analyses revealed that caregiver reports of receiving case management at any point in the first year were associated with improvement in behavioral and emotional strengths as well as a reduction in psychological and behavioral symptoms. No significant differences in rate of change were observed based on caregiver-reported receipt of individual or family therapy nor any demographic variables. These findings suggest that MeckCARES may be particularly effective when youth are receiving case management services. Additional implications for practice are discussed.
