Transfer of training for two ball-throwing tasks

The effects of training overhand ball throws to enhance underhand ball-throwing accuracy were studied with 921 Italian high school pupils (575 girls, M age = 16.5 yr., SD = 1.3; 346 boys, M = 16.5 yr., SD = 1.2) ages 14 to 18 years. A standardized test (10 underhand tennis-ball throws into the floor area delimited by an 80-cm radius wooden hoop lying on the floor 9 m from the standing pupil) was performed and scored. An Experimental group (435 girls, M age = 16.5 yr., SD = 1.3; 204 boys, M age = 16.5 yr., SD = 1.2) was randomly selected to participate in 10 weekly training periods. The set included 10 overhand throws of a rubber bouncing ball (14.5 cm diameter, weight 240 g) into a basketball hoop from 5 standardized positions (in front of the basketball hoop; at 45 degrees, 90 degrees on the right and on the left of the basketball hoop) at a distance of 4.40 m. The underhand test was repeated for both groups. On the average, boys obtained higher test scores than girls of the same age. Older adolescents had higher mean scores than younger adolescents. After 10 weeks, boys and girls of all ages improved. Mean differences between sessions were significant for the Experimental group (Student t test, p < .01). In Session 2, consistent differences between Experimental and Control groups were also found (Student t test, p < .05).     

Correlation between maternal stress and children's stress

Mothers (N = 168, M age = 37.0 yr., SD = 4.6) responded to a questionnaire of scales measuring sources of stress and symptoms of stress within themselves, and symptoms of stress in their 5-8-yr.-old children (61 girls, 98 boys; M age = 7.3 yr., SD = 1.0). Scores on all scales intercorrelated significantly, indicating a relationship between maternal stress and stress of the child. Both types of stress also correlated with the frequency of punishment of the child. Both maternal stress and frequency of punishment predicted stress symptoms in the children, maternal stress being a somewhat stronger predictor.     

Perceived relative importance of psychological and physical factors in successful athletic performance

Ratings of the perceived relative importance of psychological and physical factors for successful athletic performance were obtained from 29 men and 53 women in sports of track, swimming, soccer, volleyball, basketball, gymnastics, baseball or softball, tennis, diving, and golf, by level of competition (high school, college, and professional), and sex of athlete. The over-all rating of the relative importance of psychological factors was 39%. Significant differences in the ratings of the relative importance of psychological factors were found for sport, level, sex, sport x level, and level x sex. Ratings of the relative importance of psychological factors for successful performance in various sports increased in the order listed above. The significant effect for level and interaction of sport x level were accounted for primarily by the higher ratings given to professional golf. The significant effect of sex and the interaction of sex x level were attributable to higher ratings of the importance of psychological variables for high school women athletes as compared to high school men athletes.     

Body image and psychological well-being in adolescents: the relationship between gender and school type

Adolescents (N=1281; M age = 15.2 years, SD = 0.51 years) from a state-wide sample of schools provided information about their psychological well-being, family functioning, extraversion, and perceived physical attractiveness and weight, using a questionnaire completed at school. Consistent with previous research, girls were significantly more likely than boys to be dissatisfied with their weight and physical appearance, and these factors explained significantly more variation in self-esteem than in life satisfaction or other measures of psychological well-being. The strong relationship between body dissatisfaction and self-esteem for adolescent girls was not moderated by school type (single sex or educational). However, girls who were dissatisfied but psychologically well adjusted tended to be more extraverted, have more close friends and receive greater family support.     

Relative contributions of perceived mattering to parents and friends in predicting adolescents' psychological well-being

Perceived mattering is the psychological tendency to perceive the self as significant to specific other people. The central goal of this study was to examine whether adolescents' perceived mattering across social spheres (parents and friends) is addtive or compensatory in predicting adolescents' psychological well-being. Tests of the relative importance of adolescents' perceived mattering to parents and friends for psychological well-being were conducted using data from two convenience samples. Study 1 participants were, on the average, 17.5 yr. old and living in rural northwestern United States (N=128, 50% male, n=64; 50% female, n=64). Study 2 participants, on the average, were 16.9 yr. old, from a suburban western Canadian region (N=532, 51.4% male, n=273; 48.6% female, n=259). Hierarchical regression analysed with indicators of self-concept and behavioral misconduct as dependent variables used perceived mattering to parents and perceived mattering to friends and the interaction between these two variables as independent variables. Perceived mattering in both social spheres seemed the optimal condition for adolescents. Perceived mattering to friends "added" to perceived mattering to parents in explaining variance in assessments of psychological well-being in both studies.     

Minor psychiatric morbidity in South African secondary school pupils

This study investigated minor psychiatric morbidity ("neurotic": anxiety and depression symptoms) in rural (Black) South African secondary school pupils. The sample included 622 Grade 11 pupils (254 boys and 368 girls) in the age range of 17 to 24 years with a mean age of 19.3 yr. The inventories used were a questionnaire on the socioeconomic and family background, a Cultural Orientation Scale, a Student Stress Scale, a General Self-efficacy Scale, a Perceived Stress Scale, and the Self-reporting Questionnaire-20. The findings are that 12.6% of the pupils had a possible clinically significant psychological disorder. Contributing factors identified were interpersonal, study, finance, illness, perceived stress, low self-efficacy, and low religious orientation.     

Incremental associations between facets of anxiety sensitivity and posttraumatic stress and panic symptoms among trauma-exposed adults

The present investigation examined incremental associations between anxiety sensitivity (AS) subfactors (e.g. physical, psychological, and social concerns) and posttraumatic stress and panic symptoms among trauma-exposed adults. These effects were examined above and beyond other theoretically relevant factors, including negative affectivity and number of types of trauma exposures. The 239 participants were selected from a university- and community-based sample (129 women; mean age = 23.0 years; SD = 9.6, range = 18-65), all of whom endorsed exposure to traumatic life events. The AS psychological concerns and AS physical concerns lower order factors evidenced distinct associations with posttraumatic stress symptoms and panic-relevant symptoms, respectively. Specifically, the AS psychological concerns facet was significantly incrementally predictive of posttraumatic stress-relevant avoidance symptoms. The AS physical concerns facet was significantly incrementally predictive of panic-relevant symptoms, including anxious arousal, body vigilance, and perceived control over anxiety-related events. Results are discussed in the context of the relevant theoretical literature pertaining to shared vulnerability and comorbidity between posttraumatic stress and panic.     

Autonomous motivation: involvement in physical activity, and perceived sport competence: structural and mediator models

Students in upper secondary school (N = 231, M = 16.6 yr., SD = 1.6) were tested on involvement in physical activity, perceived sport competence, using the Perceived Competence Scale of Harter, and motivational regulation on the Self-regulation Questionnaire of Ryan and Connell. Correlations were positive among involvement in physical activity, autonomous motivation, and perceived sport competence. A hypothetical model indicated that autonomous motivation mediates the relation between perceived sport competence and involvement in physical activity. Although LISREL analysis supported this mediation, the best model fit of the data supported a structural model with involvement in physical activity (R2 = .63) to mediate between autonomous motivation and perceived competence (R2 = .47). Results are interpreted and discussed in terms of self-determination theory.     

认知评价、心理控制感、社会支持与高考压力关系的研究

采用问卷法,随机选取河北省三类中学(重点、普通、私立)324名高三考生为被试,考察了学生对高考的认知评价、心理控制感、社会支持与高考压力的关系.结果表明:(1)重点中学、普通中学学生心理控制感显著高于私立中学学生,女生在社会支持的寻求上显著高于男生;(2)积极认知评价、心理控制感和社会支持与高考压力有显著负相关,而消极认知评价与高考压力有显著的正相关;(3)消极认知评价、心理控制感和社会支持对高考压力有直接影响;而积极认知评价通过心理控制感和社会支持间接影响高考压力.     

留守儿童生活压力与孤独感、幸福感的关系:心理资本的中介与调节作用

采用问卷法对971名农村儿童进行入户调查,以考察生活压力与留守/非留守儿童孤独感、幸福感的关系以及心理资本在此关系中的作用。结果显示:与非留守儿童相比,留守儿童的生活压力与孤独感较高,心理资本与幸福感较低;生活压力对留守/非留守儿童的孤独感有正向预测性、幸福感有负向预测性,心理资本对此起部分中介作用,且在两群体中的中介过程一致;心理资本仅能有效缓冲生活压力对留守儿童孤独感、幸福感的不利影响。     

Perceived parental involvement and well-being among Ethiopian adolescents

This study examined the relationship between perceived parent academic socialisation of their children and the children’s well-being in four domains: depression, self-esteem, school adjustment, and substance use. The participants consisted of 809 Ethiopian high school students, mostly male (52.9%) (mean age = 16.8 years; SD = 1.58 years). Data were collected using self-report measures of perceived parental involvement in education support, depression, self-esteem, school adjustment, and substance use. Multiple regression analyses were used to predict aspects of child well-being from parent child academic socialisation. Generally, results showed that increased level of parental academic socialisation predicted lower depression symptoms, school adjustment problems, substance use, and also increased self-esteem among adolescents.     

The validity of using prior ratings of perceive exertion to regulate resistance exercise intensity

This investigation examined the validity of using ratings of perceived exertion (RPE) to regulate intensity during resistance exercise. 19 male (M age = 22.2 yr., SD = 2.7) and 19 female (M age = 21.4 yr., SD = 2.3) participants estimated exertion when performing the knee extension at 40% to 90% of one-repetition maximum. One week later, participants were asked to produce weights for the knee extension that elicited the feelings of exertion associated with 9, 13, and 17 on the Borg RPE scale. The weight produced at 9, 13, and 17 during the production session was compared to the weight lifted at each RPE during the estimation session. The effect sizes associated with the differences in weight lifted across sessions at each RPE were generally small in magnitude, especially at the higher intensities (ES = .40, -.09, .15, respectively). The results of this investigation support the use of RPE as a method of prescribing the intensity of resistance exercise.     

Self-determined motivation in physical education and its links to motivation for leisure-time physical activity, physical activity, and well-being in general

The present study tested a trans-contextual model based on self-determination theory of the relations between motivation in physical education, motivation in leisure-time physical activity, physical activity, and psychological well-being. Participants were 329 Norwegian upper secondary school students (M age = 16.5 yr., SD = 0.7). Students' perceptions of autonomy-supportive teachers in physical education were expected to be positively associated with students' psychological needs satisfaction in physical education, which was expected to be positively related to autonomous motivation for physical education participation. In turn, autonomous motivation for physical education was expected to be positively associated with perceived competence and autonomous motivation for leisure-time physical activity, which both were expected to be positively associated with leisure-time physical activity and psychological well-being in general. Structural equation models and bootstrapping supported the hypotheses and the indirect links between variables. Sex differences indicate that more research is needed on how to motivate girls to be more physically active in leisure time.     

Motivational profiles and flow in physical education lessons

The purpose of this study was to use cluster analysis to identify differences in goal orientation and motivational climate profiles among students in physical education classes as well as differences among the observed clusters on perceived flow experiences. 983 students of 14- to 15-yr.-olds (M = 14.8 yr., SD = 0.91) from a large Spanish metropolitan school district were participants and completed questionnaires assessing goal orientations, motivational climates, and perceived flow. Analysis showed three distinct clusters with 40.3% of the sample with a High Motivation cluster, 27.6% in a Low Motivation cluster, and 32.2% in a Mastery Motivation cluster. These three clusters differed significantly in ratings of perceived flow. Clusters also showed different composition by sex. Implications of these results with regard to instruction in physical education classes are discussed.     

Educational performance and psychological disengagement among ethnic-minority and Dutch adolescents

The authors used a questionnaire (N = 587) among ethnic-minority and majority group adolescents in The Netherlands to examine the idea that under certain conditions minority group members tend to psychologically disengage their self-evaluation from educational performance. The results showed that only among ethnic minorities, perceived discrimination in school was related to psychological disengagement. Furthermore, among both groups of participants, perceived diagnosticity of performance feedback was negatively related to disengagement. However, among the ethnic minority group this effect was found for only those participants with relatively high educational performance. The results showed that negative experiences in school can lead to psychological disengagement from the academic domain and that disengagement is not restricted to African American students.     

The role of coping, anxiety, and stress in depression post-acute coronary syndrome

Depressive symptoms are common and can affect prognosis following acute coronary syndromes (ACS). This study examined the psychological factors, coping, anxiety, and perceived stress associated with depression following ACS. Psychological variables were assessed in 15 females and 66 males (M = 57 years, SD = 12). Repeated measures at 2, 12, and 24 weeks post-ACS compared depression, anxiety, perceived stress, and coping resources as determined by the Cardiac Depression Scale, Beck Depression Inventory-II, State Trait Anxiety Inventory, Perceived Stress Scale, and Coping Resources Inventory. Depression, anxiety, and perceived stress remained high in the depressed group across time. Coping scores at 2 weeks post-ACS predicted depression scores at 24 weeks post-ACS. It appears that trait anxiety and coping resources are related to depressive symptoms post-ACS.     

Perceived parental warmth and adjustment among Ethiopian adolescents

This study aimed to investigate the relationship between adolescents’ perception of parental warmth and their self-esteem, school adjustment and depression symptoms. Data were collected from 809 adolescents (female=47%; mean age=16.8 years; SD=1.58) from four different high schools in Ethiopia. The data were analysed for differences in perceived parental warmth and adjustment by gender. Results suggest higher levels of parental warmth to be associated with comparatively lower school adjustment and depressive symptoms as well as higher self-esteem in girls rather than boys. A gendered effect seems to explain parent warmth influences of the personal and school adjustment of Ethiopian adolescents.     

Prediction of goal orientation and perceived competence on intensity and direction of precompetitive anxiety among adolescent handball players

This study explored the main and interactive effects of goal orientations and perceived competence on intensity and direction of the symptoms of precompetitive cognitive and somatic anxiety. 109 handball players from 16 high school teams (M = 16.2 yr., SD = 1.5) participated. All were asked to complete the Task and Ego Orientation in Sport Questionnaire, Perceived Competence Questionnaire, and a modified version of the Competitive State Anxiety Inventory-2. Using separated multiple hierarchical regression analyses, direction of the symptoms of precompetitive somatic anxiety was predicted by perceived competence and interaction of ego orientation x perceived competence. Perceived competence and the interaction of ego orientation x task orientation x perceived competence were significant predictors of direction of the symptoms of precompetitive cognitive anxiety. The results suggest that perceptions of competence and task orientation moderate the relationship between ego orientation and direction of the symptoms of precompetitive anxiety.     

Psychological stress-factors and concentrations of immunoglobulins and complement components in humans

Relationships between two types of occupational stress, one chronic and one acute, and plasma immunoglobulin and complement components were measured. The first group comprised female primary school teachers ( N =40) subjected to long-lasting work stress. The second group comprised male merchant navy students ( N =38) subjected to a series of short-lasting fear-inducing 20 meter drops in a life boat specially built for rescue operations from oil platforms. Significant correlations were found between personality factors, immunoglobulins and complement components in the teacher group, but not amongst the merchant navy students. For the teachers, personality traits correlated negatively with concentrations of IgA and IgG. IgM concentrations correlated with the more immediate work-related problems reported by the teachers. In a multiple regression analysis, psychological factors explained between 32% (IgM) and 15% (IgG) of the interindividual variance, when sex, age and job seniority and employment factors were controlled for. Psychological factors may therefore, at least on longlasting occupational stress groups, correlate with immune processes. The data support the concept of the importance for psychological factors in immunological function.     

Psychological Distress and Associated Factors Among a Sample of Pregnant Women in South Africa

We sought to identify the prevalence of psychological distress and associated factors among pregnant women who were patients at antenatal primary care clinics in a South Africa district. A cross-sectional study using systematic sampling was conducted among 1497 pregnant women (age range=18 to 47 years; mean age=26.6 years, SD=6.1; Black African=98%), with a mean gestational age of 6.5 months (SD=1.6). They completed the Kessler Psychological Distress Scale, a measure of psychological distress. Results showed high rates of severe psychological distress (26.5%). Increased distress was in multivariate analysis associated with having had an STI (other than HIV), being unhappy about current pregnancy, and HIV positive. Identification of pregnant women with psychological distress in public health clinics is crucial for effective and appropriate targeted interventions.
