This study investigated the impact of a building-resilience intervention on coping and posttraumatic growth (PTG) in a convenience sample of 94 breast cancer survivors. PTG was divided into constructive and illusory components, based on the two-sided Janus face model (Maercker & Zoellner, 2004). We operationalized constructive PTG as an improvement in both PTG and coping, and illusory PTG as an improvement in PTG only. An 8-session group intervention was delivered to 49 women (mean age = 51.5 years, SD = 10.7) who completed self-report questionnaires at baseline and at 6 months follow-up; a control group of 45 women only completed questionnaires. More than half the participants (n = 53; 56.38%) reported increased PTG at 6 months (mean change = 0.56, SD = 0.48, η(2) = .58). The increase in both PTG and positive coping was significantly greater in the intervention group than the control group (B = 0.23 for PTG, and B = 0.35 for positive coping). Further, a higher proportion of constructive PTG (vs. illusory PTG) was reported by the participants in the intervention group (89.3%), as compared to the control group (56.3%; z = 2.57). The distinction between constructive and illusory PTG has clinical implications for interventions promoting coping and growth among cancer survivors.

OBJECTIVES The objectives of the current study were to identify (a) different post cancer treatment adaptation profiles; (b) factors that predict these adaptation profiles; and (c) transitions in post cancer-treatment adaptation profiles and trajectories in a sample (N = 198) of female breast cancer patients over a 2-year period. METHOD Latent class analysis (LCA) was used to idenitfy profiles of post cancer treatment adaptation, based on a combined pattern of responses to observable indicators of distress, coping strategies, and posttraumatic growth. latent transition analysis (LTA) was used to track trajectories, based on the probabilities of transitions among latent classes. RESULTS Four postcancer treatment adaptation profiles were found: (a) distressed, (b) resistant, (c) constructive growth, and (d) struggling growth. CONCLUSIONS The majority of transitions between different adaptation profiles occurred between 6 and 12 months after treatment. These findings offer theoretical and practice implications regarding posttraumatic growth in breast-cancer patients by distinguishing between profiles of adaptation and highlights a previously unidentified profile-struggling growth. These results contribute to the theoretical understanding of the complex relationship between growth, distress, and coping. (PsycINFO Database Record

In situations of cumulative trauma, it is often unclear why some people remain resilient, whereas others experience distress, and how likely these responses are to change over time. To investigate the constancy of responses to cumulative trauma, stability and change in posttraumatic distress and resistance (as defined by no evidence of clinical symptoms) were assessed twice in 140 Israeli children and mothers exposed to continual rocket attacks over approximately 7 years, when the children were 2-4 (Time 1) and 9-11 years of age (Time 2). Measures included trauma exposure, posttraumatic and depressive symptoms, and child behavioral problems. We identified 4 longitudinal courses (LCs): resilient (resistance at Time 1 and Time 2), recovered (clinical distress at Time 1 and resistance at Time 2), developed symptoms (resistance at Time 1 and clinical distress at Time 2), and chronic distress (clinical distress at Time 1 and Time 2). Results showed more stability than change in the frequencies of resistance at both times of measurement. The resilient LC was the most common longitudinal course for both mothers and children. Multinomial regression models indicated that maternal posttraumatic symptoms predicted the recovered and chronic distress LCs of the children.

This study presents the first known randomized controlled study evaluating the effectiveness of somatic experiencing (SE), an integrative body‐focused therapy for treating people with posttraumatic stress disorder (PTSD). There were 63 participants meeting DSM‐IV‐TR full criteria for PTSD included. Baseline clinical interviews and self‐report measures were completed by all participants, who were then randomly assigned to study (n = 33) or waitlist (n = 30) groups. Study participants began 15 weekly SE sessions, whereas waitlist participants waited the same period, after which the second evaluation was conducted. All participants were evaluated a third time after an additional 15 weeks, during which time the waitlist group received SE therapy. Pretreatment evaluation showed no significant differences between groups. Mixed model linear regression analysis showed significant intervention effects for posttraumatic symptoms severity (Cohens d = 0.94 to 1.26) and depression (Cohens d = 0.7 to 1.08) both pre‐post and pre‐follow‐up. This randomized controlled study of SE shows positive results indicating SE may be an effective therapy method for PTSD. Further research is needed to understand who shall benefit most from this treatment modality.

Purpose. To evaluate the long-term effect of group intervention on enhancing cognitive emotion regulation (CER) strategies in female patients with early-stage breast cancer. Methods. The sample included 174 patients who were diagnosed with early-to-mid stage breast cancer, completed adjuvant therapy, and agreed to fill out demographic and cognitive emotion regulation questionnaires (CERQ). About half of the patients (86, 49.4%) chose to participate in an 8-session group intervention (intervention group) while the others (88, 50.6%) did not (comparison group). The structured intervention for enhancing coping strategies with special emphasis on emotion regulation was conducted at the oncology unit at Rabin Medical Center by 2 experienced therapists. Preliminary effects on CER evaluated 6, 12, and 24 months postintervention were compared to the CER of a group of patients that opted not to participate in the group intervention. Results. In the intervention group, the long-term effect (from baseline to 24 months) was assessed using the mix models module. Significant interaction effects were found for both the Negative CER scales (F(3, 268 ,404) = 3.66, P = .01) and for the Positive CER scales (F(3, 271 ,660) = 5.12, P = .002). No statistically significant differences in socio-demographic characteristics and medical variables were observed between the intervention and comparison groups. Conclusion. Our findings indicate that a group intervention aimed at empowerment of coping strategies had positive long-term outcomes that reinforce adaptive coping strategies and improve less effective strategies of cognitive emotion regulation.

This study examined whether maternal depression, mother–child relationships, and maternal perceived social support mediate the associations between child’s exposure to multiple traumatic events and behavioral problems. We recruited a representative sample of 904 Israeli (Jewish and Arab) mothers and their 2- to 6-year-old children. Data collection was conducted through structured face-to-face interviews with the mothers between July and November 2011. All measures were completed by the mothers. We used the child’s and mother’s exposure to political violence questionnaires, Child Behavior Checklist (CBCL), a short version of the Parental Acceptance–Rejection Questionnaire (PARQ), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Medical Outcomes Study (MOS) Social Support Survey. The research study model was tested using path analysis. The model showed a very good fit to the data, suggesting that maternal rejection, maternal depression, and social support play an important role in child’s behavioral problems in the context of multiple traumatic events. Higher levels of maternal rejection were significantly associated with greater children behavior problems. Maternal rejection mediated the associations between maternal depressive symptoms and child’s behavioral problems. Maternal perceived social support mediated the associations between child’s exposure to multiple traumatic events and child’s behavioral problems; child’s exposure to multiple traumatic events was associated with lower levels of maternal perceived social support. In turn, lower levels of perceived social support were associated with higher levels of behavioral problems. In conclusion, in accordance with the “social stress framework,” social support has a mediation role in the association between exposure to traumatic events and child’s behavioral problems. Thus, enhancing social support to mothers to young children in the context of multiple traumatic events is essential for children resiliency.
