Construct validity of the adolescent resilience scale

The aim of this study was to assess the construct validity of the Adolescent Resilience Scale which measures the psychological features of resilient individuals. Research involving this scale, the Negative Life Events Scale, and the General Health Questionnaire was conducted with a group of 207 Japanese undergraduate students (104 men and 103 women; M age = 20.2 yr., SD =.9). A cluster analysis for the Negative Life Events Scale and General Health Questionnaire yielded three clusters: (1) mentally healthy with little experience of Negative Life Events, (2) poorer mental health with many experiences of Negative Life Events, (3) mentally healthy despite many experiences of Negative Life Events. These three groups were defined as (1) Well Adjusted, (2) Vulnerable, and (3) Resilient, respectively. Mean differences in scores on the Adolescent Resilience Scale among the three groups were subjected to one-way analysis of variance. The mean scores of both the Well Adjusted and Resilient groups were higher than that of the Vulnerable group, and therefore support the construct validity of the Adolescent Resilience Scale.

Characteristics and clinical relevance of postgastrectomy syndrome assessment scale (PGSAS)-45: newly developed integrated questionnaires for assessment of living status and quality of life in postgastrectomy patients.

BackgroundLack of a suitable instrument to comprehensively assess symptoms, living status, and quality of life in postgastrectomy patients prompted the authors to develop postgastrectomy syndrome assessment scale (PGSAS)-45.MethodsPGSAS-45 consists of 45 items in total: 8 items from SF-8, 15 items from GSRS, and an additional 22 items selected by 47 gastric surgeons. Using the PGSAS-45, a multi-institutional survey was conducted to determine the prevalence of postgastrectomy syndrome and its impact on everyday life among patients who underwent various types of gastrectomy. Eligible data were obtained from 2,368 patients operated and followed at 52 institutions in Japan. Of these, data from 1,777 patients were used in the current study in which symptom subscales of the PGSAS-45 were determined. We also considered the characteristics of the postgastrectomy syndrome and to what extent these symptoms influence patients’ living status and quality of life (QOL).ResultsBy factor analysis, 23 symptom-related items of PGSAS-45 were successfully clustered into seven symptom subscales that represent esophageal reflux, abdominal pain, meal-related distress, indigestion, diarrhea, constipation, and dumping. These seven symptom subscales and two other subscales measuring quality of ingestion and dissatisfaction for daily life, respectively, had good internal consistency in terms of Cronbach′s α (0.65–0.88).ConclusionPGSAS-45 provides a valid and reliable integrated index for evaluation of symptoms, living status, and QOL in gastrectomized patients.

Cross-Cultural Differences in a Global “Survey of World Views”

We know that there are cross-cultural differences in psychological variables, such as individualism/collectivism. But it has not been clear which of these variables show relatively the greatest differences. The Survey of World Views project operated from the premise that such issues are best addressed in a diverse sampling of countries representing a majority of the world’s population, with a very large range of item-content. Data were collected online from 8,883 individuals (almost entirely college students based on local publicizing efforts) in 33 countries that constitute more than two third of the world’s population, using items drawn from measures of nearly 50 variables. This report focuses on the broadest patterns evident in item data. The largest differences were not in those contents most frequently emphasized in cross-cultural psychology (e.g., values, social axioms, cultural tightness), but instead in contents involving religion, regularity-norm behaviors, family roles and living arrangements, and ethnonationalism. Content not often studied cross-culturally (e.g., materialism, Machiavellianism, isms dimensions, moral foundations) demonstrated moderate-magnitude differences. Further studies are needed to refine such conclusions, but indications are that cross-cultural psychology may benefit from casting a wider net in terms of the psychological variables of focus.

The five-factor model of personality and physical inactivity: A meta-analysis of 16 samples

A sedentary lifestyle is harmful for health; personality traits may contribute to physical (in)activity. With participant-level data from 16 samples (N>125,000), we examined the personality correlates of physical inactivity, frequency of physical activity, and sedentary behavior (in a subset of samples). Lower Neuroticism and higher Conscientiousness were associated with more physical activity and less inactivity and sedentary behavior. Extraversion and Openness were also associated with more physical activity and less inactivity, but these traits were mostly unrelated to specific sedentary behaviors (e.g., TV watching). The results generally did not vary by age or sex. The findings support the notion that the interest, motivational, emotional, and interpersonal processes assessed by five-factor model traits partly shape the individuals engagement in physical activity.

CORRELATIONS FOR ADOLESCENT RESILIENCE SCALE WITH BIG FIVE PERSONALITY TRAITS

Currently, individuals tend to encounter many unavoidable, painful events and hardships in the process of growth and development. To lead ones life adapting to these social conditions, it is necessary to maintain ones mental health even while experiencing challenging events; in other words, resilience is required. This study of 130 undergraduates focused on the Adolescent Resilience Scale which assesses capacity for successful adaptation despite challenging or threatening circumstances and examined correlations with scores on the Big Five Personality Inventory. A significant negative correlation of –.59 (p <.001) was noted for scores on the Adolescent Resilience Scale and the Neuroticism dimension of the Big Five Personality Inventory, accounting for 35% of the variance, and positive values with the Extraversion, Openness, and Conscientiousness dimensions (rs = .37, .40, .48, accounting for 14, 16, and 18% of the variance, respectively. Personalities of adolescents who have psychological traits leading to resilience may be partially predicted using these results.

The Dark Triad Traits from a Life History Perspective in Six Countries

Work on the Dark Triad traits has benefited from the use of a life history framework but it has been limited to primarily Western samples and indirect assessments of life history strategies. Here, we examine how the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) relate to two measures of individual differences in life history strategies. In Study 1 (N = 937), we replicated prior observed links between life history strategies, as measured by the Mini-K, and the Dark Triad traits using samples recruited from three countries. In Study 2 (N = 1032), we measured life history strategies using the Consideration of Future Consequences Scale and correlated it with the Dark Triad traits in samples recruited from three additional countries. While there was some variability across participants’ sex and country, the results were generally consistent in that psychopathy and (to a lesser extent) Machiavellianism were related to faster life history strategies and narcissism was related to slower life history strategies. These results add cross-cultural data and the use of two measures of life history speed to understand the Dark Triad traits from a life history perspective.

Self-construals, anger regulation, and life satisfaction in the United States and Japan

Previous studies have reported evidence that indicates differences between Western and East Asian cultures in anger regulation and its psychological consequences. However, many of these studies have focused on a specific anger regulation strategy and its relation with a psychological consequence. Here, we developed an integrated model that can comprehensively examine three different anger regulation strategies (anger suppression, expression, and control), independent and interdependent self-construals as the psychological antecedent, and life satisfaction as the psychological consequence. We estimated the model using large samples of American and Japanese adults to examine the associations between the two self-construals, three anger regulation strategies, and life satisfaction. We compared the difference in the patterns of relationships among the key constructs between the American and Japanese samples. The results confirmed previously suggested cultural differences while also discovering new culturally different paths. The results generally suggest that individual-level self-construals matter more when anger is a culturally condoned emotion (vs. condemned). The implications and limitations of the integrated model are discussed.

Specific Features of Dumping Syndrome after Various Types of Gastrectomy as Assessed by a Newly Developed Integrated Questionnaire, the PGSAS-45

Aim: Dumping syndrome is a well-known adverse outcome after gastrectomy, but the precise clinical features have not been described. The aim of this study was to examine global aspects of dumping syndrome and to explore factors affecting the intensity of dumping syndrome in a large cohort using a newly developed integrated questionnaire, the Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45. Methods: Eligible questionnaires retrieved from 2,368 patients after 6 types of gastrectomy were analyzed. The incidence, intensity and number of symptoms of early general, early abdominal and late dumping syndrome were examined across various types of gastrectomy, and clinical factors affecting the intensity of each category of dumping syndrome were identified by multiple regression analysis. Results: Dumping syndromes occurred most frequently and strongly in patients who underwent total gastrectomy with Roux-en-Y (TGRY), followed by proximal gastrectomy (PG), distal gastrectomy with Billroth-I, distal gastrectomy with Roux-en-Y, pylorus-preserving gastrectomy (PPG) and local resection (LR), in that order. Significant positive correlations among different categories of dumping syndromes were observed. TGRY, female sex, younger age, division of the celiac branch of the vagus nerve, PG and shorter postoperative period were independently related to worse dumping syndrome. Conclusions: Dumping syndromes were most common after TGRY and least common after PPG and LR among the various gastrectomy procedures. Type of gastrectomy and several clinical factors were related to the intensity of dumping syndrome. PGSAS-45 could offer a useful tool for evaluating dumping syndrome after gastrectomy.

Mo1767 Development and Validation of Pgsas-45, an Integrated Questionnaire to Assess Postgastrectomy Syndrome

Background: Gastrectomy with lymph node (LN) dissection was considered as the gold standard for early gastric cancer (EGC) in the past. However, expansion of the criteria for endoscopic treatment has been currently proposed. This study aims to investigate the histopathologic determinants and outcomes of EGC in order to redefine the current treatment strategy. Methods: The gastric cancer tumor registry at our institution was reviewed. Sixtyseven patients were identified who underwent either endoscopic mucosal resection (EMR) or gastrectomy for EGC or high grade dysplasia between 2006 and 2011. A retrospective analysis was performed on the medical records of these patients. Mean follow-up period was 21+/-18 (1-73) months. Results: The study population consisted of 25 (37.9%) Asians, 24 (36.4%) Caucasians, 11 (16.7%) Hispanics, 7 (10.6%) African-Americans. The incidence of lymph node metastasis was 3.1% in Asians and 17.1% in non-Asians, respectively. Nine patients underwent EMR and 58 patients underwent gastrectomy with LN dissection. Among the latter group, eight (13.8%) patients had LN metastasis. Subgroup analysis comparing the histopathologic characteristics of T1b with T1a EGC was performed; nine (36.0%) patients with T1a and 11 (40.7%) patients with T1b had diffuse type histology (p=0.26). The incidence of lymph node metastasis was 4.0% with T1a in comparison to 25.9% with T1b (p=0.03). The survival rate for the T1b group (92.6%) did not differ significantly from that of the T1a group (93.5%) during the follow-up period. Conclusions: EGC in Asian Americans is less likely to be associated with LN metastases than non-Asian EGC regardless of depth or histotype. In our small series with ethnic diversity, patients with T1b EGC had significantly higher LN metastasis rate but did not have a significantly different survival rate from those with T1a, indicating that gastrectomy with LN dissection should remain the standard strategy for T1b EGC.

Factors affecting the quality of life of patients after gastrectomy as assessed using the newly developed PGSAS-45 scale: A nationwide multi-institutional study

AIM To identify certain clinical factors other than the type of gastrectomy which affect the postoperative quality of life (QOL) of patients after gastrectomy. METHODS The postgastrectomy syndrome assessment scale (PGSAS)-45 was designed to assess the severity of symptoms, the living status and the QOL of gastrectomized patients. It consists of 45 items, of which 22 are original items while 23 were retrieved from the SF-8 and Gastrointestinal Symptoms Rating Scale questionnaires with permission. A nationwide surveillance study to validate PGSAS was conducted and 2368 gastric cancer patients who underwent various types of gastrectomy at 52 medical institutions were enrolled. Of these, 1777 patients who underwent total gastrectomy (TG) reconstructed with Roux-Y (n = 393), distal gastrectomy (DG) reconstructed with Billroth-I (n = 909), or DG reconstructed with Roux-Y (n = 475) were evaluated in the current study. The influence of the type of gastrectomy and other clinical factors such as age, sex, duration after surgery, the symptom severity, the degree of weight loss, dietary intake, and the ability for working on the postoperative QOL (i.e., dissatisfaction for daily life subscale, physical component summary and mental component summary of the SF-8) were examined by multiple regression analysis (MRA). In addition, importance of various symptoms such as esophageal reflux, abdominal pain, meal-related distress, indigestion, diarrhea, constipation and dumping on the postoperative living status and QOL were also appraised by MRA. RESULTS The postoperative QOL were significantly deteriorated in patients who underwent TG compared to those after DG. However, the extent of gastrectomy was not an influential factor on patients’ QOL when adjusted by the MRA. Among various clinical factors, the symptom severity, ability for working, and necessity for additional meals were the most influential factors to the postoperative QOL. As for the individual symptoms, meal-related distress, dumping, abdominal pain, and esophageal reflux significantly affected the postoperative QOL in that order, while the influence of indigestion, diarrhea and constipation was insignificant. CONCLUSION Several clinical factors such as the symptom severity (especially in meal-related distress and dumping), ability for working and necessity for additional meals were the main factors which affected the patients’ well-being after gastrectomy.
